The document is divided into sections describing the master plan, the affected environment, alternatives considered during the planning stages of the master plan and impacts that may result from the proposed development. Additionally, separate studies of traffic, air quality, flora and fauna, archaeology, and the market, conducted by technical consultants, are provided as appendices. Consulted agencies and organizations were requested to submit their comments, jcorrections, and/or clarifications on the draft environmental impact statement to the County of Hawaii Planning Department. 1 1 1 1 i t t 1 j ANb'WWnSONVN011oncioa1 1 F 1 LN01103S SECTION 1 INTRODUCTION AND SUMMARY 1.1 INTRODUCTION AND BACKGROUND The Office of Housing and Community Development (OHCD) of the County of Hawaii is proposing a unique, quality affordable residential development in Waikoloa Village, in the South Kohala district of West Hawaii. This master planned development is proposed to contain approximately 1,200 single- and multi-family housing units all of which will be available for rent or sale in the affordable price ranges, as defined by federal, state and county standards. The project site is currently undeveloped and is located at the north end of the existing Waikoloa Village. Ownership of 279 acres of the 340-acre site is being conveyed from the present land owner, Waikoloa Land Company, to the County of Hawaii through an agreement between the two parties. Development of the remainder parcel will be undertaken by Waikoloa Land Company in conjunction with other developers. Master planning of the Waikoloa Affordable Housing project began in summer 1989 when the Office of Housing and Community Development issued a request for proposals to develop a conceptual master plan including preliminary infrastructure development plans. In September 1989, R. M. Towill Corporation was selected to prepare the Master Plan. A land use plan, backbone infrastructure plans, and development costs have been completed. This Final Environmental Impact Statement (FEIS) will evaluate the Master Plan 1 components — i.e., the land use plan and backbone infrastructure plans. While the developer of this project may have a somewhat different plan, it will not be substantively different from the current Master Plan. Thus, the impacts, analysis, and applicable mitigation measures as discussed in this environmental impact statement will apply to the overall development project. r 1.2 INTENDED USES OF THIS DOCUMENT This environmental impact statement has been prepared in accordance with Chapter 343, Page 1-1 r INTRODUCTION AND SUMMARY SECTION 1 Hawaii Revised Statutes and the rules and regulations of the Office of Environmental Quality Control. It has been determined that an envi nmental impact statement is required pursuant to Chapter 200 of Title 11, Administra Jve Rules, Subchapter 5(b). r The purpose of the environmental impact statement is W provide information to public officials and members of the community on the nature of the subject action; to assess existing environmental conditions of the property and surrounding areas; to evaluate potential impacts that may result from development of the project and to propose 1 mitigating measures for those impacts; and to consider alternatives to the proposed action. r 1.3 DEVELOPMENT SUMMARY Applicant: Office of Housing and Community Development Accepting Authority: Mayor of the County cf Hawaii Approving Agency: Planning Department r Tax Map Keys: 6-8-02:31 and por. 26 Third Division Area: 279 acres r Location: South Kohala District, at the north end of the existing Waikoloa Village; bour ded to the west by conservation r lands and to the north east and south by vacant lands that are planned for fl.ture Waikoloa development.

Southeast of the project area are residential ur its nestled in the rolling hills of Waikoloa Village. The south slope of Haleakala Crater or Maui is visible on a clear day. Paniolo Drive, an 80-foot wide public right-of-way, curre tly provides access to the site from Waikoloa Road. The completed or improved porti n of Paniolo Drive terminates near the eastern border of the site. Extension of Paniolo Drive over an existing dirt road is expected to be completed no later than March 1993 wt en development in the eastern section of Waikoloa Village occurs. Ownership of this parcel is currently being conveyed by aikoloa Land Company to the County of Hawaii for the purpose of enabling the County to develop affordable housing units on this site. Surrounding parcels are owned by Waikoloa Land Company/Waikoloa Development Company and several other development ompanies. 1.5 SUMMARY OF PROBABLE IMPACTS AND MITIGA1 ION MEASURES 1.5.1 Traffic The proposed project will increase traffic on the existing and proposed roadways in the area of the project. Projected traffic volumes resulting fro rn development of the Waikoloa Affordable Housing project include the following: PROJECT TRAFFIC A.M. Peak Ho ir P.M. Peak Hour ail nter x nter xRt Land Use (Parameter) v v h v v h v h Single-family (560 d.u.) 3644 104 283 346 203 Multi-family (840 d.u.) 5024 76 343 263 124 Park (9.2 acres) 336 6 If 8 23 Commercial (5,000 s.f.) 4435 169 1 182 174 Church (75,000 s.f.)577 4 1 21 18 Total: 14,016 359 817 820 542 NOTE: vpd = vehicles per day vph = vehicles per hour Page 1-6 i SECTION 1 INTRODUCTION AND SUMMARY t t The Waikoloa Affordable Housing project proposes a loop road system in which two 60- foot wide rights-of-way will intersect the improved extension of 80-foot wide Paniolo Drive. 1 The total estimated project traffic volumes at full development will impact the existing regional transportation network, however, at or near over capacity conditions will exist at peak periods even without the affordable housing project. t 1.5.2 Air Quail tThe major short-term air quality impact will be the potential emission of significant quantities of fugitive dust during project construction phases. Uncontrolled fugitive dust emissions from construction activities are estimated to amount to about 1.2 tons per acre per month. During the period of construction, emissions from engine exhausts (primarily consisting of carbon monoxide and nitrogen oxides) will also occur both from on-site construction equipment and from vehicles used by construction workers and from trucks travelling to and from the project. Mitigation measures will include the establishment of a regular dust-watering program and covering of dirt-hauling trucks in compliance with State of Hawaii Air Pollution Control Regulations. The primary long-term air pollution impact from the project will arise from the increased motor vehicle traffic associated with the project. Potential increased levels of carbon tmonoxide concentrations along roadways leading to and from the proposed development will be the primary concern. The"with the project"carbon monoxide concentrations along troadways in the project vicinity will unavoidably be higher at several locations compared Page 1-7 INTRODUCTION AND SUMMARY SECTION 1 to the"without project" case, but worst-case concentraticii is will remain within the national standards. With or without the project, the more stri gent State standards may be exceeded near traffic-congested areas. The highest concentrations will occur in the vicinity of Queen Kaahumanu Highway at Waikoloa Road. Mitigation measures available to minimize traffic-related air pollution include the improvement of roadways, reduction of traffic or reduction of individual vehicular emissions. Roadway improvements recommended in the traffic study will be implemented to move traffic efficiently through the project area. Traffic will be reduced to the extent possible by encouraging bus use, car pooling, and/or the adjustment of local school and business hours to begin and end during off-peak times. Reduction of individual vehicular emissions is beyond the control of the project. Some long-term impacts on air quality also could occur due to indirect emissions from power generating facilities supplying the project with ele ricity and from the disposal of waste materials generated by the project. Impacts will be small, however, due to the magnitude of the project electrical and solid waste demands compared to the present and future County demands. Indirect emissions from project electrical demand could be reduced somewhat by utilizing solar energy design features to the maximum extent possible. This would include installing solar water heaters, designing homes and building spaces so that window positions maximize indoor light without unduly increasing indoor heat, and using landscaping where feasible to provide afternoon shade to cut down on the use of air conditioning. 1.5.3 Socio-Economic Conditions The Waikoloa Affordable Housing project will increase the population in the area by an estimated 3,600 persons, assuming average persons per household of 3.0 to 3.3. This total represents approximately 15 percent of the South Kohala district's population per DBED's M-K Series B and County Planning Departmen 's population projections by the Page 1-8 SECTION 1 INTRODUCTION AND SUMMARY year 2005. The Waikoloa Affordable Housing project is expected to provide a wide range of housing opportunities, all in the affordable range, for varied levels of family incomes. Total housing units are estimated at approximately 1,200 to 1,400 units for the development. This development will provide badly needed affordable housing in the West Hawaii region; and by increasing the supply of affordable housing units, the project will facilitate an expanded labor force for the area's resorts. 1.5.4 Topoaraphy and Soils Slopes in the project area range from 0 percent to over 20 percent. The northern portion of the site has an average slope of 6 to 10 percent and the southern portion has an average slope between 11 percent and 20 percent. Elevations range from 550 feet above sea level near the makai boundary to 900 feet near the mauka boundary of the site. Two soil types are found on the project site: Kawaihae (KNC) and Very Stony Land rVS). Hard pahoehoe lava bedrock can be found at a depth of about 33 inches in the areas where Kawaihae soils occur. Bedrock occurs at a depth of 5 to 20 inches in areas where Very Stony lands occur. The varying topography and elevations of the project site will necessitate careful siting of roadway and other utility systems as well as residential lots, in order to minimize construction costs for this affordable housing project. 1.5.5 Flora and Fauna According to the Botanical Survey Report written by Char & Associates, the proposed project is not expected to have a significant impact on flora as the site consists primarily of cultivated lands. According to the Survey of Avifauna and Feral Mammals undertaken by Phillip L. Bruner, there are no rare, threatened or endangered vertebrate animal species known to exist on the project site. Page 1-9 INTRODUCTION AND SUMMARY SECTION 1 1.5.6 Water The Waikoloa Water Company owns the wells, reservoirs, and primary transmission mains 1 that supply potable water to Waikoloa Village. The Waik loa Water Company's potable water wells draw from the Waikoloa aquifer. It has been determined that the project will require a 12-inch water line laid along the entire length cif backbone roadways. The proposed project will require approximately 560,OOD gallons per day at build-out. The Waikoloa water system has adequate capacity to provide for these needs. 1.5.7 Sewer At present, there is no sewer system in the immediate icinity of the project area. The nearest sewer system is located approximately 7,000 fe it southwest of the project site, and serves the commercial and multi-family areas of Waik loa Village. This existing sewer system is not available for use by the proposed project Preliminary analysis of the sewer system needs for the project indicates that the project will generate a total average flow of 0.5 million gallons per day (mgd). The proposed on- site improvements will primarily include 8-inch and 2-inch gravity lines. Sewage treatment facilities are to be provided off-site by Waikoloa Sanitary Sewer Company. The plans for these new facilities are still at a very early stage. The new sewage treatment plant and its associated effluent disposal syste will be designed, constructed, and operated in accordance with applicable Federal, State and County rules and regulations. 1.5.8 Drainage A new drainage system consisting of a ten-foot concrete channel running along Paniolo Drive, and two mauka-makai concrete channels to divert runoff to offsite drainageways will be constructed as part of the project. Other major improvements will include 2-foot and 5-foot channels to be built on the project site. Among the necessary infrastructure improvements and associated costs to be borne by the project, drainage improvement Page 1-10 SECTION 1 INTRODUCTION AND SUMMARY costs are the highest -- approximately $12 million. Unlined channels may be possible under certain conditions. Other offsite mitigation measures are being evaluated and may further reduce direct project costs. A mitigation measure will be to attribute the cost of constructing the ten-foot channel along Paniolo Drive to Transcontinental Development Company, based on the Agreement dated February 25, 1988. In this scenario, cost of this item would be attributed to the original landowner, thereby reducing the drainage improvement costs to $8.6 million. 1.5.9 Solid Waste aSolid waste generated by the project when fully completed is expected to amount to about 10 tons of refuse (approximately one 12-ton truckload) per day. At present, the refuse district handles about 100 tons daily. The nearest existing solid waste transfer station is located at Puako, however, a new transfer station is being planned near a former quarry site immediately adjacent of Waikoloa Village. This transfer station should be operational before this project breaks ground. Currently, solid waste is disposed of at the Kailua-Kona landfill located at Kealakehe. The Kealakehe Landfill is scheduled to close within the next 24 months and is not expected to continue to function as the refuse disposal site for the West Hawaii region. A new sanitary landfill site has been selected, and plans are being put together for its development. This facility will accommodate the proposed project's solid waste disposal needs. 1.5.10 Power and Communications At present power and communications are provided by an existing underground duct bank containing a 750 MCM cable (14.47 KVY) which originates from a substation located mauka of the Waikoloa Village general store and runs along Paniolo Avenue to the project area. A new substation will be necessary to provide power to the project. The Hawaii Electric Light Company (HELCO) is developing additional electrical energy generating capacity, and therefore it is expected that HELCO will be able to provide the required Page 1-11 INTRODUCTION AND SUMMARY SECTION 1 electricity to meet this additional demand. 1.6 ALTERNATIVES CONSIDERED The economic mix of housing units was reviewed and ane lyzed to preliminarily determine financially feasible scenarios. Numerous cash flow analyses were conducted, each containing different sets of assumptions, such as varVing per square foot building construction costs, and dwelling unit sizes. One scenario indicates that total revenues from the sale of 1,000 units are $129.4 million, while tou I development costs (including building construction, subdivision or on-site development, backbone infrastructure, sales/processing fees, indirect costs for design, management, loan points, contingencies at 15%, and developer's profit at 5% of revenues) are $131.7 million. At an annual deficit financing rate of 12%, the deficit after financing will be $17 million. Achieving a balance between the project's social objectives of providing all housing units at affordable rent and sales price levels while maintaining the project's overall economic feasibility will have a significant influence on the final mi of unit types and sizes. It is recognized that the modification of certain subdivision standards may result in t significant cost savings, and may result in more affordab a housing. These modifications need, however, to ensure that such cost-saving method , (1) will not result in health and safety risks; (2) will not result in significant added post- onstruction maintenance costs for the County and/or for the residents; (3) will not have n adverse visual impact; (4) will clearly result in a greater number of affordable houses and/or lower prices for some or all of the homes. 1.7 NECESSARY PERMITS AND APPROVALS A.

Envisioned is a 1,200 to 1,400 dwelling unit mix of single family and multi-family homes on finished lots (see Figure 2-1). Master planned as a 100 percent affordable residential community, the project will offer unique rental and homeownership opportunities to families whose incomes fall within the 50 percent to Hula Mae Program financing limits. The project will also include a parcel for churches and a small commercial area near the Paniolo Drive entrance. A community park will be located next to the commercial/churches area at the entrance to the project at Paniolo Drive. A public school site is planned near the southeastern edge of the project site near the Ho'oko Street and Paniolo Drive intersection. 2.2 THE MASTER PLAN Single family detached dwellings are proposed in the Master Plan to have lots averaging 7,500 square feet in size, depending on the topography and location of the lot. Some of these lots will have dramatic views of the ocean and mountains. The selected developer may ultimately provide smaller lots in order to achieve a greater number of house lots for project feasibility. In response to the topographic conditions, steep slopes will be utilized as buffers between clusters of houses. Other open spaces will be created by the preservation of drainageways. The use of unbuildable lands for open space creates a more pleasant, natural environment. Multi-family units will vary from duplex units with lot sizes of 3,750 square feet per unit, to other multi-family housing types such as row houses, six-plex or eight-plex units. Gross project density for multi-family projects will be no more than 15 units per acre. To maintain the low density nature of the overall development, multi-family projects will not be more than 15 acres in size.

Honok*.MewaN n Jo ep-na hose Page 2-2 SECTION 2 PROJECT DESCRIPTION An overall sense of neighborhood identity will be created by physically identifiable villages" or neighborhoods within the 279 acre project. This will be achieved through the creative use of roads, drainageways, topography, views and vistas, as well as through varying site layouts and architectural design. The Land Use Plan identifies a total of 14 development clusters. A 9-acre community park has been located at the Paniolo Drive entrance to serve the wider Waikoloa Village community. This recreational facility will also function as an entry feature/statement to the overall development. A drainage retention parcel of 7 acres has been located at the makai or western end of the project site. This parcel will be grassed over and will serve a dual function as a second recreational field for this family-oriented project. An 8.6-acre parcel has been set aside for churches and a small convenience commercial area adjacent to the community park at the Paniolo Drive entrance. This grouping of uses is proposed for the optimum use of parking facilities at this site. Near the southeastern boundary of the project site is a future 36-acre public school and recreation complex located near the Ho'oko Street and Paniolo Drive intersection. Waikoloa Land Company is in the process of conveying this land to the State Department of Education for this purpose. The major roadway network consists of 50-foot and 60-foot wide rights-of-way, with curbs, gutters and sidewalks, and dry wells for drainage. Roadway grades were maintained at a maximum slope of eight-percent,with a few exceptions where ten or twelve-percent was used because of the steep character of the area. The Land Use Plan shows a 60-foot right-of-way to be reserved in the mid-section of the site. This right-of-way would be a part of a collector roadway that would be constructed to provide the project site and other area developments with a second route to Waikoloa Road. Page 2-3 PROJECT DESCRIPTION SECTION 2 Off-site infrastructure systems, including access roadway, potable water, and sewage treatment and disposal will be provided by the Waikoloa Land Company at no cost to the County or to the prospective developer.

Preliminary backbone infrastructure requirements and associated costs were documented in a report prepared by R. M. Towill Corporation in June, 1990. These findings are subject to further in-depth study. The following infrastructure system requirements were discussed in the report: 2.3.1 Wastewater System At present, there is no sewer system in the immediate vicinity of the project area. The nearest sewer system is located approximately 7,000 feet southwest of the study area and serves the commercial and multi-family areas of Waikoloa Village. This existing sewer system is not available for use by the proposed project. A preliminary analysis of the sewer system needs for the project indicates that the project will generate a total average flow of 0.5 million gallons per day (mgd). The proposed on-site improvements will consist primarily of 8-inch and 12-inch gravity lines. A new sewage treatment and disposal facility will be provided by the Waikoloa Land Company, through its subsidiary, the Waikoloa Sanitary Sewer Company. This new facility is presently in the early stages of planning. Thus, the capacity and general mechanical characteristics of the plant, as well as its service area, location, and effluent disposal method have yet to be determined. Preliminary concepts for this new facility suggest an off-site location near the makai boundary of the County's land. The new sewage treatment and disposal system will be designed and constructed in accordance with applicable Federal, State, and County rules and regulations. 2.3.2 Water System The Waikoloa Water Company owns the wells, reservoirs and primary transmission mains that supply potable water to Waikoloa Village. The Waikoloa Water Company's potable water wells draw from the Waikoloa aquifer. These wells, known as Parker wells No. 4 Page 2-5 PROJECT DESCRIPTION SECTION 2 and No. 5, and Waikoloa Wells No. 1 and 2 (under constr ction), are located at the 1,200- foot level nearly five miles inland from Puako Bay. These wells tap high quality water (25 ppm chloride content) from the Waikoloa aquifer. The point of connection to the water system from the project area is an 8-inch main at Paniolo Drive and Ho'oko Street. It has been determined that the project will require a 12-inch water line laid along the entire length of main roadway. Fire hydrants were assumed to be spaced every 300 feet. 2.3.3 Drainage System The approximately 58,000-acre watershed located mauka of the site produces about 12,000 cubic feet per second (cfs) of runoff during a "1 0-year" storm, which naturally collects in Kamakoa Gulch. Kamakoa Gulch is a natural Major drainageway which forms the northern boundary of the project site. Under existing conditions, a portion of this mauka-generated runoff runs through the project site b fore entering Kamakoa Gulch. The preliminary analysis, using the 100-year, 24-hour storm, indicates that the project will generate an on-site increase in peak runoff of approximately 380 cts. Based on the County of Hawaii's Standards of 5 cfs per well of 20 foot depth, 76 dry wells are required to control the increase in runoff. Because a portion of lhe runoff runs through the site before entering Kamakoa, a ten-foot concrete channel rur ining along Paniolo Drive will be used to divert this runoff to Kamakoa before it can enter Me site. Alternatively, a channel could be considered along the mauka boundary of othei developments that are located mauka of the County's project site. A subdivision drainage plan provided by Imata and Pssociates shows over 750 cfs entering the project site from future developments located mauka of the site. Two concrete channels are needed to divert runoff to off ite drainageways. A trapezoidal channel, with a ten-foot bottom width and 1:1 side slopes, will run along the lower, or west side of Paniolo Avenue to collect approximately 1,600 cfs of runoff from the 1,500 acre drainage area directly above the site and divert it irito Kamakoa Gulch, which runs Page 2-6 SECTION 2 PROJECT DESCRIPTION along the north side of the project site. A second similar channel, with a 5-foot bottom width, running from Paniolo Drive to the lower end of the project site is needed to carry approximately 550 cfs to an off-site drainageway that eventually empties into Kamakoa Gulch. Unlined channels may be possible, provided that erosion can be controlled and that maintenance does not become a major problem. Swale and dry well systems will be used to collect runoff from roads and road rights-of- way. Dry wells are to be spaced every 250 feet along both sides of all roadways. The swales, drywells, and related drainage facilities will need to be properly maintained. 2.3.4 Electrical/Telephone An existing underground duct bank which contains a 750 MCM cable (14.47 KVI) originates from a substation located mauka of the Waikoloa Village's general store and runs along Paniolo Avenue to the project site. Conduits to accommodate cable and telephone lines are also located within this same duct bank. The project's electrical and telephone utilities will be located underground. In general, underground electrical and telephone lines within dedicable roadways will be concrete jacketed. 2.3.5 Infrastructure Costs Preliminary infrastructure cost estimates were prepared in June, 1990 by R. M. Towill Corporation. The following is a summary of the estimates: Roadway System and Landscaping. This cost includes the construction of the backbone roadways with curbs, gutters, and sidewalks, and of 2 major and 5 minor intersections. 2,996,000.00 Sewer System. The system will include 8" and 12" gravity sewers and manholes. 836,000.00 Page 2-7 PROJECT DESCRIPTION SECTION 2 Water System. This will involve a 12" water line, f re hydrants and fittings. 988,000.00 Drainage System. These major infrastructure improvements assume 2-foot, 5-foot, and 10-foot channels, catch basins, dry wells, 1 841ch drains, and culverts. There is also an assumption that the cost to construct the 10-foot channel will be assumed by Transcontinental Development Corporation per the Memorandum of Agreement dated February 25, 1988. 8,614,000.00 Power and Telephone. It is assumed that these itilities will be underground. 1,461,000.00 Site Work. This cost involves excavation for roadways and drainage channels. 1,442,000.00 A drainage study for Kamakoa Gulch is needed and is currently underway. The cost of any required drainage improvements to Kamakoa Gulch will depend on what is designed and any cost sharing agreement that can be worked oi it with other affected parties. The total cost estimate for these infrastructure im rovements (including a 15% construction contingency, and 10% for survey and desic n work) is $20,665,000. This will be approximately $17,221 per dwelling unit if the total r umber of units is 1,200. 2.4 MIX/TYPES OF UNITS The Waikoloa Affordable Housing development will ha/e units for rent and for sale to families whose incomes are between 50% of the Coun 's median income ($16,000) to Hula Mae program limits ($45,800). Page 2-8 SECTION 2 PROJECT DESCRIPTION In order to achieve the County's objectives relative to affordable housing, the distribution of the types of units will be focused on providing as many units as possible for families at the lower end of the income scale. The overall project size will be approximately 1,200 to 1,400 units. A recommended mix of unit types and prices is provided below: 200 Multi-Family rental units -- possibly developed by the State; a 1,000 Multi-Family and Single Family For Sale units. The multi-family rental units could be developed under the State's Rental Housing System RHS). Under this program, rental projects are financed with the proceeds of tax-exempt trevenue bonds issued by the State's Housing Finance and Development Corporation HFDC). The RHS could be used in conjunction with HFDC's Rental Assistance Program which provides rent subsidies to lower the rent for eligible tenants. Consideration will also be given to Policy C(7) of the State Housing Functional Plan which strives to integrate special needs housing into new and existing neighborhoods. The suggested mix of for-sale homes is as follows: Sale Price of Units Income Group Per Unit Type of Unit 400 100% of Median 95,952 Duplex/Fourplex 200 120% of Median 117,876 Single Family 200 140% of Median 140,160 Single Family 200 Hula Mae Limit*167,000 Single Family Numbers are currently being updated in the Hula Mae program. The $167,000 sales price may be feasible for families within the Hula Mae income limits; however, new mortgage limits have not yet been made official. Page 2-9 PROJECT DESCRIPTION SECTION 2 1 2.5 PROJECT CASHFLOW SUMMARY As part of the master planning process, a projection of project development costs including financing) and revenues from home sales w s prepared, assuming project build out within six years. The Cash Flow Analysis model has been summarized and is shown below as Table 2-2. The following assumptions were made in the preparation of this cash flow analysis: 1) Sales price limits for homes targeted for each of the income groups are: Price Income Group 95,952 100% of Median 117,876 120% of Median 140,160 140% of Median 167,000 Hula Mae Limit* (see above) 2) The assumed mix of the units will be 40% or 4 0 units for the 100% of median income group, 20% or 200 units for the 120% oi median income group, 20% or 200 units for the 140% of median income grc up, and 20% or 200 units for households whose incomes are up to the Hula Mae program limit. 3) Cost of construction for the multi-family units is assumed to be $75 per square foot, while for single family units it is $70 per square foot. 4) Dwelling unit sizes are assumed as: up to 800 square feet for duplex/fourplex 1 units; 1,000 square feet for units built for the 120° of median income group; 1,200 square feet for the 140% of median income gro p; and 1,250 square feet for the Hula Mae limit group. t 5) The project will be developed in 6 years, with the dwelling units being constructed starting with year 2; 77 units constructed in Year 2; 311 units constructed in Year Page 2-10 SECTION 2 PROJECT DESCRIPTION 3; 272 units constructed in Year 4; 119 units constructed in Year 5; and 221 units constructed in Year 6. Unit counts for each year were derived from the Land Use Plan. Several iterations of the cash flow analysis were conducted, each containing different sets of assumptions, such as varying per square foot building construction costs, and dwelling unit sizes. The rental units were not included in the analysis as these will be developed either by the State or private developer(s). The total number of units for sale was 1,000 in this analysis.

Total revenues from the sale of the 1000 units are $129.4 million, while total development costs (including building construction, subdivision or on-site development, backbone infrastructure, sales/processing fees, indirect costs for d sign, management, loan points, contingencies at 15%, and developer's profit at 5% of venues) are $131.7 million. At an annual deficit financing rate of 12%, the deficit after financing will be $17 million. Project backbone infrastructure requirements are assumed to conform to County subdivision standards, and to the requirements of the County Department of Public tWorks. However, it is recognized that the modification of certain standards may result in significant cost savings, and may result in more affordable housing opportunities. These modifications need, however, to ensure that such cost-saving methods, (1) will not result in health and safety risks; (2) will not result in sig ificant added post-construction maintenance costs for the County and/or for the residents; (3) will not have an adverse visual impact; and (4) will clearly result in a greater number of affordable houses and/or lower prices for some or all of the homes. Page 2-12 1 SECTION 2 PROJECT DESCRIPTION Any substantive cost-savings methods in infrastructure and subdivision design will help to reduce the project deficit that is indicated in Table 2-2. Further, if the construction cost per square foot-- i.e., $75 per square foot for multi-family units, and $70 per square foot for single family units -- can be reduced, additional reduction of the project deficit can be realized. 2.6 PROJECT SCHEDULE Construction of the model units in the Phase 1 development is expected to begin in the first quarter of 1991, while construction of the rest of the homes is projected to begin during the third quarter of 1991. Construction of the County's portion of the project will commence with the construction of the initial infrastructure -- this is expected to begin in early 1992. Construction of homes can be expected to begin in mid-1992. 1 1 Page 2-13 1 1 1 t 1 1 1 1 r r SECTION 3 r r r r r r r r r r r r r r r PHYSICAL ENVIRONMENT r r t SECTION 3 PHYSICAL ENVIRONMENT 3.1 TOPOGRAPHY AND SOILS r3.1.1 Topooraphv Slopes in the project area range from 0 percent to over 20 percent. Gently rolling hills, 1 low-lying grasslands with scattered kiawe trees and rock outcroppings characterize the terrain of the project site. The northern portion of the site has an average slope of 6 to 10 percent and the southern portion has an average slope between 11 percent and 20 percent. Approximately 40 percent of the site consists of slopes of 0 to 5 percent; 33 percent consists of slopes of 6 to 10 percent; 17 percent consists of slopes of 11 to 20 percent; and 10 percent of the site consists of slopes greater than 20 percent (see Figure 3-1). Elevations range from 550 feet above sea level near the northwest boundary of the project site to 900 feet near the southeast boundary. Kamakoa Gulch and an unnamed gulch border the northern and southern boundaries, respectively. Impacts and Mitiaation The site's varying topography with its gradually increasing elevation in the makai to mauka direction will necessitate some excavation and grading of the ground for construction of the homes. This natural topographic variation also offers creative site planning opportunities in that houses of varying architectural styles including split-level and pole designs can be incorporated to adapt to these conditions. Design adaptation to the existing topography offers the potential to develop more interesting and attractive residential structures. However, the disadvantages of working with a site that has a varying topography are that excavation, infrastructure systems design, and multiple architectural designs add to overall development costs. Such additional costs may affect the financial feasibility of any development, but this is particularly so for a project whose homes are all targeted to fall within the "affordable" range. Page 3-1 t r s r r r r a r r r r ri r r r r r CO W w y,. iAj liil' W Z SECTION 3 PHYSICAL ENVIRONMENT Costs can be contained through careful siting of residential lots, roadways, and 1 utility systems. 3.1.2 Soils The U. S. Department of Agriculture, Soil Conservation Service (SCS) identified and mapped two soil types within the project site: Kawaihae (KNC) and Very Stony Land rVS). The Kawaihae soil type characterizes the major portion of the project area. This I series consists of somewhat excessively drained extremely stony soils that formed in volcanic ash. A representative profile contains a surface layer of dark reddish brown extremely stony very fine sandy loam about two inches thick. Below this is dark reddish Ibrown and dusky red stony silt loam and loam. Hard pahoehoe lava bedrock is at a depth of about 33 inches. Kawaihae land is commonly used for pasture, wildlife habitat and recreation areas (see Figure 3-2). The southeastern sector is characterized by the Very stony land (rVS) soil type. This soil consists of very shallow soil material and a high proportion of Aa lava outcrops. Between the lava outcrops and in the cracks of the lava, the soil material extends to a depth of 5 to 20 inches. The typical vegetation is a sparse cover of grass and kiawe trees in dry areas. The erosion hazard is slight. Very Stony Land is commonly used for pasture, watershed and wildlife habitat. Impacts and Mitigation No significant impacts are expected with regard to existing soils and soil conditions on the project site. Standard grading procedures, in accordance with State and County public works requirements will be adhered to in the design and 1 site preparation stages of development. Any specific considerations in the grading plan(s) will be adhered to during the engineering design phase of the project. Page 3-3 T7 CY 0 CI) CL nf cc CD 0 CL i W. m N, 2 LL co 6V JLL caw fill CAICL SECTION 3 PHYSICAL ENVIRONMENT The ash-soil in the northeastern section of the site appears to be subject to rapid erosion. It should be landscaped as soon as possible after disturbance. This would also mitigate problems with dust. 3.2 SEISMOLOGY AND VOLCANIC ZONES The Island of Hawaii is classified as Seismic Risk Zone 3 on a scale of 1 to 4 (4 being higher). The earthquake of 1868 was estimated to have had a magnitude of 7.25 to 7.75 on the Richter scale at its epicenter along the Kau District Coast; and at the Waikoloa Beach Resort, located 5.5 miles west of the study area, intensities were only slightly less. The 1951 and 1975 earthquakes were estimated to have had intensities of about 5 at the iWaikoloa Beach Resort. The study area location on the flanks of Mauna Kea places the property in Lava Flow Risk Zone 8 for Mauna Kea and close to the edge of the boundary of Lava Flow Risk Zone 3 for Mauna Loa. Lava Flow Risk Zones 1 to 9 - 1 being highest risk - are based upon the probability of coverage by lava flows. The risk of damage from new lava flows from 1 either volcano within the next 100 years is remote. Impacts and Mitigation Site development standards and criteria applicable to areas classified as Risk Zone 3 for seismologic risks shall be adhered to by the developer(s) of this site. Although the risk of direct damage from new lava flows within the next 100 years is reportedly remote, the possibility of a lava flow from Mauna Loa crossing and blocking one or more of the major area roadways should be considered. 3.3 CLIMATE Regional and local climatology significantly affect the air quality of a given location. Wind, temperature, atmospheric turbulence, mixing height and rainfall all influence air quality. Although the climate of Hawaii is relatively moderate throughout most of the state and most of the year, significant differences in these parameters may occur from one location to another. Most differences in regional and local climates within the state are caused by the mountainous topography. Page 3-5 1 PHYSICAL ENVIRONMENT SECTION 3 South Kohala, the district in which the project site iE located, is situated on the northwestern side of the island of Hawaii. The topography of this island is dominated by t the great volcanic masses of Mauna Loa (13,653 feet), Mauna Kea (13,796 feet), and of Hualalai, the Kohala Mountains and Kilauea. The island consists entirely of the slopes of these mountains and of the broad saddles between them. Mauna Loa and Kilauea, located on the southern half of the island, are still acti a volcanoes. The site of the proposed project occupies a portion of the lower northvvestern slope of Mauna Kea, extending from an elevation of about 550 feet near the northwest boundary up to an elevation of about 900 feet near the southeast boundary. Hawaii lies well within the belt of northeasterly trade Winds generated by the semi- permanent Pacific high pressure cell to the north and east. Nearly the entire western coast of the island of Hawaii, however, is sheltered from the trade winds by high mountains, except when unusually strong trade winds sweep through the saddle between the Kohala Mountains and Mauna Kea and reach the are as to the leeward side. Due to wind shadow effects caused by the terrain, winds ir the South Kohala area are predominantly light and variable. Local winds such as land/sea breezes and/or upslope/downslope winds tend to dominate the wind pattern for the area. During the daytime, winds typically move onshore because of seabr eze and/or upslope effects. At night and during the early morning hours, winds generally are land breezes and/or drainage winds which move downslope from the east arid out to sea; oftentimes, early morning drainage winds are quite strong for a few hotirs just near sunrise and then subside. Calms occur about 9 percent of the time at nearby Kawaihae. In Hawaii, the annual and daily variation of temperature depends to a large degree on elevation above sea level, distance inland and exposur to the trade winds. Average temperatures at locations near sea level generally are warmer than those at higher elevations. Areas exposed to the trade winds tend to have the least temperature variation, while inland and leeward areas often have the most. The project site's leeward location and low-level elevation result in a relatively moderate temperature profile compared to windward locations near sea level. At Kam ela, located to the northeast of Page 3-6 SECTION 3 PHYSICAL ENVIRONMENT the project and at an elevation on about 2,700 feet, average daily minimum and maximum temperatures are 55 degrees Fahrenheit and 73 degrees Fahrenheit, respectively. The extreme minimum temperature on record at this location is 34 degrees Fahrenheit, and the extreme maximum is 90 degrees Fahrenheit. Temperatures at the project site are estimated to be about 5 to 10 degrees warmer on the average than those at Kamuela due to the lower elevation. Rainfall in Hawaii is highly variable depending on elevation and on location with respect to the trade winds. The lower elevations of South Kohala are some of the driest areas in the state. Some of the rainfall occurs in conjunction with winter storms, and some occurs during summer afternoons and evenings as a result of the onshore and upslope movement of moisture laden marine air. Annual rainfall reported for Waikoloa Village during 1988 was about 18 inches. This may vary substantially from one year to the next. Humidity at the project site is relatively constant year round. It is generally below 40 percent during the late morning and afternoon hours. Impacts and Mitigation The project will have no significant impacts on the existing climatic conditions. The dwelling units and other project buildings are expected to be constructed to take advantage of the natural ventilation that the prevailing winds can provide in this area. 3.4 HYDROLOGY AND DRAINAGE The project area is bordered on the northern side by a major drainage way, Kamakoa Gulch, which originates in the upper slopes of Mauna Kea and terminates in the coastal plain above the Puako shoreline. A large portion of the site is part of the Kamakoa Gulch drainage area. Branch tributaries, which vary in size, enter the site on the east side, traverse through the site and join the main branch located downstream of the site. It appears from field observations, that these branch tributaries are partially diverted toward Page 3-7 PHYSICAL ENVIRONMENT SECTION 3 of the project site (Figure 3-3). The approximately 58,000 acre watershed located maul,a of the site produces about 12,000 cubic feet per second (cfs) of runoff during a "10 year" storm," which naturally runs through Kamakoa Gulch. Bordering the site to the south is an unnamed gulch with a tributary area that originates in the existing subdivision to the southeast. Only a small r ortion of the study area drains to this gulch. As indicated on the drainage map and through field obSE rvations, it is evident that over the years, the project site has been subjected to significar t drainage impacts from areas mauka. The proposed project is situated above the Underground Injection Control line (UIC line) as established by the State Department of Health. According to the Map Index and Street Index of the Federal Emergency Management Agency's latest Flood Insurance Rate Map (FIRM), dated July 16, 1990, the project area lies within the borders of Panel 283C, which has not yet been printed. However, all areas covered by this panel have been designated Zone X, areE s determined to be outside the 500-year flood plain (U.S. Army Engineer District, Sept., 990). 1 Low-lying areas adjacent to Kamakoa Gulch, however, appear to be prone to minor flooding based on field observations conducted during the master planning process September 1989 to March 1990). A detailed analysis of the project's drainage system and floodway boundaries will be conducted for the design and development phases. The detailed study is intended to verify and refine the preliminary engineering analysis, aid to set floodway boundaries along the northern border which is defined by Kamakoa Gulch.

Page 3-8 r r r r a f r r r r r r r r rr r r r r CV) a LV coLU T o ; J g S LLIL l i l a•• Z J Qca3aLL m PHYSICAL ENVIRONMENT SECTION 3 Impacts and Mitigation Preliminary backbone infrastructure requirements and associated costs were projected by R. M. Towill Corporation in June, 1990. The following describes and summarizes the necessary system improvements and assessment of the impacts: County of Hawaii subdivision standards which will apply to the affordable housing project require that surface runoff levels shall be no more than the levels prior to development. Because a portion of the mauka-generated runoff flows through the County site before entering Kamakoa Gulch, a ten-foot concrete channel running along Paniolo Drive will be constructed to divert this runoff to Kamakoa before it can enter the project site. This will be a trapezoidal channel with a ten-foot bottom width and 1:1 side slopes, and will collect approximately 1,600 cfs of runoff from the 1,500 acre drainage area directly mauka of the project site and divert it into Kamakoa Gulch. The Preliminary Engineering Report shows this channel located on the lower, or west side of Paniolo Drive. However, further study indicated that the preferred location for this channel would be the upper, or east side of Paniolo Drive. This issue will have to be resolved through further discussions with Transcontinental Development Corporation. The cost to construct this channel has been estimated at $3.36 million. Other offsite mitigation measures are being evaluated and may alter the drainage improvements that will be required. As a mitigation measure to minimize project infrastructure costs, the $3.36 million cost to construct this channel should not be incurred by the Waikoloa Affordable Housing project due to the fact that the origin of the mauka flows are other developments off-site. I To control project-generated surface flows, a second similar channel, with a 5-foot bottom width, running from Paniolo Drive to the lower or makai end of the project site, is needed to carry approximately 550 cfs to an off-site drainageway that eventually empties into Kamakoa Gulch. Other onsite improvements include swale Page 3-10 SECTION 3 HYSICAL ENVIRONMENT and dry well systems which will be used to collect runoff from roads and road rights-of-way. Dry wells and catch basins are to a spaced every 250 feet along both sides of all roadways. Total estimated cclst for these improvements is approximately $8.6 million. Given the project's location above the UIC line care must be taken to avoid contamination of groundwater resources. Among other measures, UIC permits will be required for all proposed drywells, and disposal of sewage effluent by means of injection wells will not be permitted. 3.5 FLORA AND FAUNA 3.5.1 Flora Char and Associates conducted a botanical survey on tie project site in August, 1988. This report is included in its entirety as Appendix A in this Final Environmental Impact Statement. The survey was conducted with the use of a walk-throw h method with plants identified by sight. Plants that could not be positively iden ified were collected for later determination by comparison with known specimens in he herbarium and reference to standard taxonomic literature. Taxonomy of ferns is k ased on Wagner and Wagner 1987). Taxonomy and nomenclature of the flowering lants follows Wagner et al. (in press). The entire site is a prehistoric lava field, though the substrate was of two distinct types. In the northeast portion of the site, the soil was a fine yel owish ash, with occasional rock outcroppings. Erosional features revealed that the ash was, at least in some places, more than three feet thick and divided into two soil zones marked by a change in color. The upper layer was approximately one foot deep. A herd of approximately 50 goats was found in a large cave in the south bank of Kamakoa Gulch. Such evidence as tracks and droppings indicated that they travel widely through the site, and may contribute to the composition of the vegetation. Page 3-11 PHYSICAL ENVIRONMENT SECTION 3 In general, vegetation in the northeast portion of the site consists of rolling grasslands with widely scattered trees. The soil is a deep, yellow ash with occasional rock outcroppings. In the southwest section, vegetation consists of savannah-scrubland. This substrate is overlain by a thick, weathered a'a. The soil is thinner and rock outcroppings predominate. For the most part, the species composition is the same throughout the site. In specific areas,fountain grass (Pennisetum setaceum) predominates along the dirt road I and Paniolo Avenue, and in the bottom of Kamakoa Gulch. Away from the road the predominant grass is native hard-stemmed love grass (Eragrostis atropiodes). Where erosion or disturbance by animals was heaviest, the exotic buffel grass (Cenchrus cillaris) has replaced the native grass. The only tree species on the site is kiawe Proso is allida . This tree is found in increasing density toward the southwest section of the property. A total of 46 plant species were found, an extremely low number for an area of this size. Of these, 40 (87 percent) were identified as exotic weeds or introduced plants, and 6 (13 percent) native, or presumed native plants. Impacts and Mitigation No listed, proposed, or candidate threatened and endangered species, as designated by the Federal and/or State governments (U.S. Fish and Wildlife 1 Service 1985; Herbst 1987) were found on the site. The Eragrostis grassland appears to be a remnant native plant community, but is so disturbed that essentially only the grass remains. Most other native plants associated with this grassland community are either so uncommon on the site as to have all but disappeared, or like wiliwili (Erythrina sandwicensis) and a'ali'i (Dodonaea viscose , were observed a short distance outside of the site, but were not found on the site itself. Native plants should be used in future landscaping of the site. A number are both attractive and adapted to the present climate, while others would thrive with Page 3-12 SECTION 3 FHYSICAL ENVIRONMENT common landscape practices. Some control should be exercised in bringing in exotic species. A number of undesirable weedy species (toxic, invasive, or both) could potentially escape from cultivation and become serious problems in the future. Examples are a cactoid euphorbia Eu h rbia lactea and Aloe, both of which were found on or near the site. The presence of exploded ordnance on the site suggests that unexploded ordnance may be present, though none was seen during the survey. Another problem is that the ash-soil in the northeastern ialf of the site appears to be subject to rapid and severe erosion. It should be Iz ndscaped as soon as possible after disturbance. This would also mitigate problE ms with dust. 3.5.2 Fauna A three-day field survey of the avifauna and feral marnmals at the study area was conducted by Phillip L. Bruner in August, 1988. This report in its entirety is included as Appendix B in this document. The objectives of the field survey were to: Document what bird and mammal species occur on the property or may likely occur given the range of habitats available. Provide some baseline data on the relative densitV of each species. Determine the presence or likely occurrence of any native fauna particularly any that are considered "endangered" or "threatened.' If such occur or are likely to occur on the property identify what features of the habitat may be essential for these species and suggest how those resources may be protected. No endemic or native birds were recorded during the course of the field survey. The Short-eared Owl or Pueo Asio flammeus sandwichens s is relatively common on the Island of Hawaii and potentially could occur on the site (Berger 1972, Hawaii Audubon Society 1984, Pratt et al. 1987). This endemic subspecies is listed as endangered on Page 3-13 1 PHYSICAL ENVIRONMENT SECTION 3 Oahu by the State of Hawaii Department of Land and Natural Resources Division of Forestry and Wildlife, but not elsewhere in Hawaii. No other endemic birds would be expected given the location and type of habitat. Migratory shorebirds migrate to Hawaii between the months of August and May. Some juveniles will stay through the summer months (Johnson et al. 1981, in press). Of all the shorebird species that winter in Hawaii the Pacific Golden Plover (Pluvialis fulva) is the most abundant. Plovers prefer open areas such as mud flats, lawns and grazed pasture land. They arrive in Hawaii in early August and depart to their arctic breeding grounds during the last week of April (Johnson et al. 1981). A total of only two plover were counted during the survey. These plover were seen flying over the property. No plover were actually seen on the ground. Both plover observed had some remaining breeding plumage which would indicate they had recently returned from the arctic. No resident indigenous or native birds were recorded or expected in this habitat at this project site. Further, no resident indigenous or native seabirds were observed on the property. A total of nine species of exotic or introduced birds were recorded during the field survey. No species were abundant. Populations of all species were smaller than expected. Given the type of habitat and its location and based on earlier studies (Bruner 1979, I1980, 1984a, 1984b, 1984c, 1985a, 1985b), and information provided in Berger (1972), Hawaii Audubon Society (1984) and Pratt et al. (1987) the following exotic species might also be expected to occur on the property: Ring-necked Pheasant (Phasianus colchicus , Erckel's Francolin (Francolinus erckelii , California Quail (Callipepla californical, Japanese Quail Coturnix iaponica), Barn owl T to alba), Yellow-billed Cardinal (Paroaria ca itata), Northern Mockingbird Mimus polvalottos), Saffron Finch Sicalis flaveola), Lavender Waxbill Estrilda caerulescens), House Finch (Caroodacus mexicanus) and House Sparrow Passer domesticus). Page 3-14 SECTION 3 PHYSICAL ENVIRONMENT The feral mammals observed during the survey werE the Small Indian Mongoose Herpestes auropunctatus), dogs and goats. No rats, mice or cats were recorded but it would be highly unusual if these ubiquitous mammals did not occur on the property. Without a trapping program it is difficult to draw conclusio s about the relative abundance of rats, mice, mongooses, dogs, cats and goats. However, it is likely that their numbers are typical of what one would find elsewhere in similar habitat on the island. Records of the endemic and endangered Hawaiian Hoary Bat Lasiurus cinerus semotus are sketchy but the species has been reported from Hawaii (Tomich 1986). However, none were observed on this field survey. Bats were found at locations makai of the project site (Bruner 1984d). Overall, results of the survey indicated that the study a ea provides a limited range of habitats which are utilized by the typical array of exoti bird species expected at this elevation and in this type of environment. Some species typically found on the island in this habitat were not recorded during the survey. This may be due to the very dry conditions found at the study area. No endemic birds or seabirds were recorded nor were they expected. Also, no threatened or endangered species were encountered and there waE no evidence suggesting such species being in the project area. Impacts and Mitigation The proposed development would create a more diversified habitat than presently exists and would likely result in the following &anges in the avifauna and feral mammals on this site: 1.Some species might experience a dec ine in numbers of individuals. Species in this situation could be Gray Francolin, and perhaps Spotted Dove. Page 3-15 PHYSICAL ENVIRONMENT SECTION 3 2.Populations of all exotic species, with the exception of Gray Francolin and Spotted Dove, will likely increase dramatically following the proposed development. Residential property to the east of the site clearly demonstrates this effect. A drive/walk through census of birds in the residential area revealed more total species and greater numbers of individuals of all species. 3.6 NOISE 3.6.1 Existing Conditions The project site is undeveloped. The closest development to the project site are single- family homes mauka of Paniolo Avenue. The houses nearest to the project site are about 2,000 feet from the project boundary. The site is not near any major highways and is not in the flight path of any airports. Impacts and Mitigation Construction-related (grading and infrastructure development) noise may impact on the neighboring homes located near the project site due to the general wind pattern during the day. Certain construction equipment may be required to be muffled to minimize the higher noise levels. These higher noise levels will, however, be short-term impacts. Also, since the nearest houses are about 2,000 feet from the project boundary, significant noise impacts are not expected. Once the project has been developed, there will be some noise impact from vehicular traffic on Paniolo Drive and on project roadways. However, the relatively low volume of traffic, coupled with speed limits of 35 mph or lower, will be mitigating factors. Noise impacts from roadways are therefore not expected to be a significant problem. Page 3-16 1 SECTION 3 PHYSICAL ENVIRONMENT 3.7 AIR QUALITY A report on the air quality was prepared in October 1990 and is included in this document as Appendix C. Present air quality in the proj ct area is mostly affected by air pollutants from natural, agricultural and/or vehicular s urces. Natural sources of air pollution emissions which may affect the project area but cannot be quantified very accurately include ocean, plants, wind-blown dust anc volcanoes. Of these natural sources of air pollution, volcanoes are the most significz nt. Volcanic emissions have chronically plagued the project area since the latest eruption phase of Kilauea Volcano began in 1983. Air pollution emissions from Kilauea consist primarily of sulfur dioxide. After entering the atmosphere, these sulfur dioxide emissions are carried away by the wind and either washed out as a id rain or gradually transformed into particulate sulfates. Although emissions from Kilaue are vented more than 60 miles southeast of the project site, the prevailing wind patterns eventually carry the emissions into the Kona and South Kohala areas. These emissions can be seen in the form of volcanic haze (vog) which persistently hangs over the area. The American Lung Association is currently studying the character and concentrations of volcanic air pollution in the Kona area, but to date no results of the study are available. Although the project is located between two major regional arterial roadways, Queen Kaahumanu Highway and Mamalahoa Highway, it is several miles from either and unlikely to be significantly affected by the exhausts of motor veh cles traversing these roadways. Any air pollution from motor vehicles is likely confined to limited areas near intersections where and when traffic congestion occurs during poor dispersion conditions. The State Department of Health operates a network of air quality monitoring stations at various locations around the state. Unfortunately, verf little data are available for the Island of Hawaii, and none are available for the South Kohala area specifically. As is indicated in Table 3-1, the only existing monitoring dati anywhere near the project site consist of sulfur dioxide and particulate measurements that were made about 30 miles to the south at Kealakekua during 1985 and 1986. During this two-year period, Page 3-17 PHYSICAL ENVIRONMENT SECTION 3 1 measurements of 24-hour average sulfur dioxide concentration at this location were consistently low with daily mean values ranging from less than 5 to 12 milligrams per cubic meter (mg/m3). No exceedances of the state/national 24-hour AAQS for sulfur dioxide were recorded. Twenty-four hour average particulate concentrations ranged from 4 to 28 milligrams per cubic meter. Hence, no violations of the state AAQS were measured.

These are primarily motor vehicle related air pollutants. Lead, ozone, and nitrogen dioxide typically are regional scale problems; concentrations of these contaminants generally have not been found to exceed AAQS elsewhere in the state. Carbon monoxide air pollution, on the other hand, typically is a microscale problem caused by congested motor vehicular traffic. In traffic congested areas such as urban Honolulu, carbon monoxide concentrations have been found to Page 3-18 SECTION 3 PHYSICAL ENVIRONMENT occasionally exceed the state AAQS. Present concentrat ons of carbon monoxide in the project area are estimated later in this study based on athematical modeling of motor vehicle emissions. Impacts and Mitigation 1. Short-Term Construction-Related Impacts and Miticiation Short-term direct and indirect impacts on air quality could occur due to project construction. There are two potential types of air pollution emissions which could directly result during construction: (1) fugitive dust from vehicle movement and site excavation; and (2) exhaust emissions from on-site construction equipment. State of Hawaii Air Pollution Control Regulations stipulate that emissions of fugitive dust from construction activities cannot be visible beyond the property line. Thus, an effective dust control plan for the construction phases will be necessary to mitigate these impacts. In dust-prone areas like South Kohala, limiting the area that can be disturbed at any given time, regular watering of exposed soil areas, applying chemical soil stabilizers, use of mulches and erosion control fabrics and/or using wind screens may be necessary. Control regulations also specify that open-bodied trucks be covered when in motion. Paving of parking areas and roads and establishing landscaping as early in the construction process as possible can also lower the potential for fugitive dust emissions. On-site mobile and stationary constructior equipment will also emit some air pollutants in the form of engine exhausts. The largest of this equipment is usually diesel-powered. Nitrogen oxides emissions from diesel engines can be relatively high compared to gasoli e-powered equipment, but the standard for nitrogen dioxide is set on an annual basis and is not likely to be violated by short-term construction oquipment emissions. Carbon monoxide emissions from diesel engines, however, are low and should be Page 3-19 PHYSICAL ENVIRONMENT SECTION 3 insignificant compared to vehicular emissions on roadways. Indirectly, slow-moving construction vehicles could obstruct normal traffic flow to the extent of increasing overall vehicular emissions. However, this can be mitigated by moving heavy construction equipment during periods of low traffic volume. Likewise, the schedules of commuting construction workers can be adjusted to avoid peak hours in the project vicinity. 2.Long-Term Roadway and Vehicular Movement Impacts and Mitigation The primary long-term air pollution impact from the project will arise from the increased motor vehicle traffic associated with the project. Potential increased levels of carbon monoxide concentrations along roadways leading to and from the proposed development will be the primary concern. Based on mathematical modeling of projected vehicular traffic and on atmospheric dispersion estimates of vehicular emissions (CALINE4), the proposed project carbon monoxide concentrations along roadways in the project vicinity will unavoidably be higher at several locations compared to the without project case, but worst-case concentrations will remain within the national standards. The highest concentrations will occur in the vicinity of Queen Kaahumanu Highway at Waikoloa Road. In 1997 with the project, the estimated maximum worst-case 8-hour concentration was 7.6 mg/m3 near Queen Kaahumanu Highway and Waikoloa Road; other locations studied ranged from 3.1 mg/m3 at Mamalahoa Highway and Waikoloa Road to 6.6 mg/m3 at the intersection of Paniolo Drive and Waikoloa Road. Either with or without the project, 1997 concentrations will be higher than existing concentrations at most locations. Comparing the projected values for the existing case to the AAQS, it appears that both the State and National 8-hour standards will be met during 1990. The same is true without the project in 1997 except at the intersection of Queen Kaahumanu Highway and Waikoloa Road. With the Page 3-20 SECTION 3 PHYSICAL ENVIRONMENT project, worst-case 8-hour concentrations will meet the national standard but may occasionally exceed the more atringent state standard along Waikoloa Road at Queen Kaahumanu Highway and at Paniolo Drive. Roadway improvements, reduction of traffic or reduction of individual vehicular emissions will help mitigate increased air pollution levels. Roadway improvements such as a grade-separated interchange at Queen Kaahumanu Highway and Waikoloa Road will help lower future air pollution concentrations. Also, air quality impacts near the intersection of Paniolo Drive and Waikoloa Road will be diminishec if the north-south collector road west of and parallel to Paniolo Drive is built in 1995 as planned. Air pollution impacts from vehicular emis ions can also be mitigated by reducing traffic through the use of buss s and car pooling, and/or by adjusting local school and business hours begin and end during off-peak times. It is also possible that at some point in the future, the State may adopt either a motor vehicle inspection a d maintenance program, which ensures that emission control devices are properly maintained and thereby reduces emissions, or more restrictive em ssion control standards. 3.Long-Term Pro'ect Electrical and Solid Waste Generated Impacts and Mitigation The proposed project will generate indirect emissions from power generating facilities as a consequence of electrical power usage. Peak power demand at project completion Is not expected to exceed 3 megawatts. Present generating capacity on the Big Island is 161 megawatts with most of this power provide by oil-burning generating units. Island-wide, peak power demand is curren ly 120 megawatts. Based on the ratio of peak project power demand to to al present peak power demand on Hawaii, the project power demand Will result in about a 3 percent increase in emissions from the electric utility if all project power is derived Page 3-21 PHYSICAL ENVIRONMENT SECTION 3 from fuel oil. Indirect emissions from project electrical demand could be reduced by the use of solar energy design features to the maximum extent possible. This would include installing solar water heaters, designing homes and building space so that window positions maximize indoor light without unduly increasing indoor heat, and using landscaping where feasible to provide afternoon shade to cut down on the use of air conditioning. Use of wind power generating unit, solar energy, geothermal energy, ocean thermal energy conversion and/or other alternative energy sources by the utility tinstead of fuel-burning facilities also would minimize indirect emissions from project electrical demand. Solid waste generated by the project is expected to amount to about 10 tons of refuse (about one 12-ton truckload) per day. At present, the refuse district handles about 100 tons per day. Most, if not all project refuse will likely be hauled and either landfilled or burned at another location. Most solid waste from the project will be buried at the West Hawaii Sanitary landfill, and any air pollution impacts will be minimal if the landfill is operated properly. If project refuse is burned instead at a municipal incinerator, air pollution impacts could be reduced substantially if the incinerator is fitted with pollution control equipment; i.e., electrostatic precipitators or fabric filters. Conservation and recycling programs will also reduce solid waste which would reduce any related air pollution emissions proportionately. 3.8 VIEWS The project area is located at the 700-foot elevation of the Kohala region, approximately four miles from the coastline. The predominant views from the project area are the peaks of Mauna Kea to the east, the Kohala Mountains to the north, and the Kohala coastline to the west. Southeast of the project area are residential units nestled in the rolling hills Page 3-22 SECTION 3 11 HYSICAL ENVIRONMENT of Waikoloa Village. The south slope of Haleakala Crater on Maui is visible on a clear day. Views onto the project site are of an undisturbec environment, as it is currently undeveloped. Residents of neighboring mauka houses have clear views of the Kohala coast. Impacts The project will have no significant adverse impa s on existing views. Due to the relative low-density and mix of single-family and multi-family units planned for the project, views will be enhanced rather than impedE d. The varying topography and elevations will allow the developer(s) to site buildings and homes in areas within the site to minimize significant alterations to the xisting views and view planes. The views of the project site from existing neighborhoods will be somewhat impacted due to the introduction of this residentiec I development. To mitigate this potentially adverse impact, a 50-foot planting easement which will consist of trees is proposed to run along the length of Paniolo Drive. 3.9 HISTORIC AND ARCHAEOLOGICAL RESOURCES An archaeological reconnaissance survey was conducted for the project area by William J. Bonk in August, 1988. The archaeological report in its entirety, is included as Appendix D in this document. Literature research, aerial photographs, and field reconnaissance survey methods were used to conduct the historic and archaeological resource study for the project site. The prehistoric land use pattern in the Waimea-Waikoloa area was originally subsistence horticulture and subsistence marine exploitation. By th a latter half of the 16th century, changes in this pattern occurred as the economy expanded. This trend reached its peak in the late prehistoric period of the second half of the 1 8th century (Bonk, 1985:6). As foreign ships increased in numbers at Kawaihae in the early historic period, further development of a "subsistence-trade" economy occurred. Through the 19th century, as Page 3-23 PHYSICAL ENVIRONMENT SECTION 3 1 cattle became a more important part of the economic base, the transporting of products and a money-based economic system gradually evolved. These cultural changes occurred simultaneously with the related environmental evolution in the form of botanical and zoological changes. Subsequently, this had an effect on the land surface. Exotic animals and plants began to replace endemic varieties, and these changes transformed the physical as well as cultural environment. At the Mahele of 1848, the land, Waikoloa, was awarded to George Huen Davis, son of Isaac Davis, the English companion and advisor to Kamehameha I (Soehren, 1980)." Waikoloa was regarded as "an 'ili'aina of Waimea" as Waimea developed as the "food basket' of South Kohala. In aboriginal times, before cattle, Soehren (1984) says, these lands (Waikoloa) were marginal to the Hawaiian economy, serving as a reservoir of material products such as pili grass and birds. Without an assured source of water, the midlands of Waikoloa were not able to support horticulture. Marine exploitation was more readily available for the coastal inhabitants of Waikoloa and its neighboring ahupua'a. Starting with Reinecke in 1930 and extending to the present, there is an increasing number of reports covering the lowland regions. The summarization and analysis of these data show the use of these coastal, inland and offshore areas as of economic importance in the prehistoric period. If the midlands were tmarginal, the coastal regions were of importance. This produced an attraction for people and cultural development within the coastal region, but not in the midlands. Here, only off and on incursions were made for the gathering of pili grass for the thatching of homes and other structures, and the passage through these lands on travels elsewhere, hardly a reason for settlement, or even lingering long enough to leave their cultural marks on the surface of the ground. Prior to the development of the village of Waikoloa in the early 1970's only the military left their mark on the project site. Evidence of the presence of the military (from World War II) were the remains of field communication wire as well as a number of examples of Page 3-24 SECTION 3 PHYSICAL ENVIRONMENT shrapnel fragments. Impacts and Mitigation The study reported that no sites of prehistoric or istoric significance were found on the project site. Thus, any land transformation would not be "archaeologically detrimental'. In conclusion, Bonk indicated that n further archaeological work is recommended for the project site. Notwithstanding the negative survey results, it is always possible that archaeological artifacts or human burials could be uncovered during construction. In the event of such discoveries, construction in the immediate vicinity should be halted, and the State Historic Preservation Divisioi should be contacted as soon as possible. A staff person from the Division will then assess the situation and recommend appropriate mitigation measures.

The findings of this report are summarized below. The report reviewed and addressed the anticipated housing demands created by the resort development at Waikoloa, outlined the affordable housing alternatives for the County's designated property for this purpose, and identifies the market for such housing. The report, in its entirety, is included as Appendix E in this FEIS. The demographics of consumers for the affordable housing market at Waikoloa include: I Construction workers for continued resort development along the North Kona/South Kohala coast; Permanent work force at completed hotels; General population growth resulting from continued economic growth. While housing opportunities for employees of the developments in Waikoloa cannot be reserved for these consumers exclusively, primary emphasis should be placed on their needs. 4.2 POPULATION TRENDS The County of Hawaii is the southernmost and largest island of the Hawaiian Archipelago. The land area of the County is approximately twice that of all the other islands of the State combined. Within the past twenty-five years, tourism has emerged as the primary economic activity on the island. Much of the economic growth experienced during this period can be linked with the expansion of the visitor industry. Page 4-1 SOCIO-ECONOMIC ENVIRONMENT SECTION 4 In 1970, just prior to the adoption of the County Gene ral Plan, the population in the County of Hawaii numbered 63,468. The 1970 census ount was the first to show an increase since 1930. Population peaked at 73,325, large ly as a result of the importation of labor for the sugar industry. Since 1970, the county's population has continued to grow. The 1980 census registered an island-wide population of 92,053 people representing a growth of 28,585 residents for a 45°/* increase over the 1970 census. Estimates prepare d in the 1989 Hawaii State Data Book suggest a population of 117,500 in 1988. Three sets of population projections were developed for the County's comprehensive planning review program, series A, B, and C. The rrajor variable in each of these projections is the rate of growth of the visitor industry. Series A is the most conservative projection. It assumes the demise of the sugar industry and modest expansion in the visitor industry. The overall 1985-2005 rate of growth for series A of 2.0% per annum is less than the 2.9% rate of employment growth in the County during the last five years. Series B projections were developed as a medium series. Sugar employment is maintained and the overall per annum employment grovith rate is 3.7%. Series C reflects an optimistic outlook of the County's future. It is assumed that 17,800 hotel rooms plus additional condominium units will be built in the County by 2005. The average annual growth rate of employment is 4.7%. The above described population projections are summarized below: 1 Page 4-2 SECTION 4 SOCIO-ECONOMIC ENVIRONMENT TABLE 4-1 District Distribution Year 2005 Projections) District Series A Series B Series C Puna 39,790 49,910 58,340 S.

County projections for the year 2005 indicate a shift in population from East Hawaii to West Hawaii. The county projects that by the year 2005, 45.5% of the residential population will be living in West Hawaii. Patterns and population settlement and growth are defined for the most part by an area's economic opportunities and its energy resources. The West Hawaii region has many opportunities to sustain a stable and diversified economy supported by energy resources, high technology research and development, aquaculture, diversified agriculture, commercial and sport fishing, seafood marketing and ocean research. Expansion in these areas will increase job choice and the availability of higher paying jobs. 4.3 AFFORDABLE HOUSING NEEDS/DEMAND Unpublished population estimates from a Department of Transportation study show that, within Waikoloa Village, 334 single family units, 226 multi-family units and 69 resort condos existed in 1987. Projections for 2010 show an additional 2,430 single family and 1,000 multi-family units coming on line. Projected total dwelling units by 2010 are 3,921 with a population of 11,760. Page 4-3 SOCIO-ECONOMIC ENVIRONMENT SECTION 4 The housing needs of the County of Hawaii's West Hawaii region have been documented in HUD's Housing Market Analysis report, the State's Re ional Plan for West Hawaii, the County's Infrastructure Needs Assessment report, Ouee 's Medical study, Peat Marwick and Mitchell's preliminary Kealakehe plan for the Hou ing Finance and Development Corporation, and studies done for Puako Mauka, Signal Puako and Parker 2020. Based on these studies, the projected housing demand n the West Hawaii area ranges between 1,000 units and over 2,000 units per year. Not only is there a significant pent-up demand in the area, the situation will be impacted by the thousands of construction and permanent full- and part-time hotel workers at the Ritz Carlton Mauna Lani, the soon to be completed Four Seasons at Kaupulehu, South Kohala Resort at Mauna Kea Resort, the Regent Beach-Kona at Kukio, Kohanaiki, and the Princess Hotel at Kaupulehu. This demand will be complemented with the necessary SL pport community that will come along with this hotel construction. This housing de nand can be accommodated throughout the coast, in Kona, Waikoloa, and other parts of the coast. It is reasonable to estimate that the housing demand (at prices in the 'affordable' range) at a level of 1,500 to 2,000 units per year exists in the West Hawaii area for the foreseeable future.l Definition of Affordable It has been customary to separate affordable uni s into family income categories as follows*: VERY LOW: families earning less than 0% of median income (under 16,000). LOW: families earning between 50% and 80% of median income 1 between $16,000 and $25,600). Page 4-4 SECTION 4 SOCIO-ECONOMIC ENVIRONMENT LOW/MODERATE: families earning between 80% and 120% of median income between $25,600 and $38,400). MODERATE: families earning between 120% and 140% of median income between $38,400 and $44,800). I According to the Office of Housing and Community Development (OHCD), the 1990 HUD median income estimate for Hawaii County is $32,000, assuming a household size of 4 persons. These income limits can be converted to selling price ranges. A bank and savings and 1 loan were contacted for current loan underwriting policies and they are as follows: Loan underwriting for typical bank: gross monthly income/mortgage payment 3.6 to 1 gross monthly income/mortgage and all debt 2.8 to 1 Current 30 year loans (amortization and term) have rates at approximately 10.58% per annum. I Loan to value ratios are typically 80% to 90%. Loan underwriting for typical savings and loan: Housing debt = 28% of gross monthly income Total debt = 36% of gross monthly income Page 4-5 SOCIO-ECONOMIC ENVIRONMENT SECTION 4 Current 30 year fixed loans have rates at 10.50% Loan to value ratios are typically 80% to 90%. Sales Price Ranges The various selling prices for houses within the in me groups (i.e., low, low/mod, and mod) can be computed based on the underw iting policies of the lenders and the current home mortgage terms. Category Sales Pri a Ran e Very Low Income (up to 50%) (Assume Rentals only) 1 Low Income (50% to 80%) up to $7 ,800 Low/Moderate (80% to 120%) $77,800 $117,900 Moderate (120% to 140%) 117,90 - $140,200 Rental Ranges Based on HUD evaluation standards, a projectec rent to income ratio of 30% is used. Based on this policy, the following are i dicated rental ranges for each income group. Assume: Rent is 30% of gross monthly income Annual Income Monthly ncome Rent Range Very Low up to $16,000 up to $ 1,330 up to $ 400 Low 16,000-$25,600 $1,33042,130 400 - $640 Low/Mod $25,600-$38,400 $2,13043,200 645 - $960 Moderate $38,400-$44,800 $3,20043,730 960 - $1120 NOTE: The above projections are based strictly on a family of four people. r For varying family sizes the estimated median income is adjusted; therefore the selling price and rental ranges must bD adjusted. Page 4-6 SECTION 4 SOCIO-ECONOMIC ENVIRONMENT 4.4 PROJECT IMPACTS The Waikoloa Affordable Housing Project is proposed to provide approximately 1,200 dwelling units which will all be targeted to West Hawaii households whose incomes fall within the below 50% of median to Hula Mae income ranges. Based on the analysis above, the project will provide the equivalent of about one year's demand for affordable housing in this region. While the recommended rental rates and sales prices of these units are not yet firm, the County's policy will be to provide the greatest possible opportunity to each of the groups defined and described in these categories. A major concern in West Hawaii is the affordability of housing: the cost of housing is comparatively high, while wages in the visitor industry are regarded as low. The problem is expected to become worse, given the outlook for substantial growth driven by the visitor industry. West Hawaii has experienced cycles of rapid and slow housing appreciation, and will experience similar cycles in the future. These cycles reflect both local conditions (such as rapid employment growth) and national economic conditions, such as dramatic changes in inflation and interest rates. Population and housing impacts of economic development shift over time, in ways that are not always easy to predict. For example, four recently hired new resort workers might be young singles sharing one housing unit. A generation later, these four young people might each be supporting a family of five or six, living now in four different housing units. Alternatively, the original four young workers might have left, only to be replaced by four other people sharing the same unit. Entry level employees can seldom afford to solve their housing needs in ways which are considered to be conventional; i.e., by purchase or rental of single-family homes or condominiums in an improved neighborhood for a nuclear family. Instead, most find less expensive solutions, including staying with their parents or other relatives until they can Page 4-7 SOCIO-ECONOMIC ENVIRONMENT SECTION 4 afford their own place; finding a roommate to share the i ent; commuting long distances from non-conforming subdivisions where housing is less expensive; and renting units often illegal) from owners of single-family homes, and thereby supplementing the income of these house owners.

The report findings, analysis, and recommendations are summarized in this section. The traffic study in its entirety can be found in this Final Environmental Impact Statement as Appendix F. 5.1.1 Existing Roadways Located in the South Kohala district on the island of Hawaii, the site is located just north of the existing Waikoloa Village. Vehicular access to the site will be provided by the northerly extension of Paniolo Drive (see Figure 5-1). A. Local Roadway System Paniolo Drive serves as a collector road for Waikoloa Village. Paniolo Drive has an 80-foot right-of-way and its southern terminus intersects Waikoloa Road and Pua Melia Street forming a cross intersection. The posted speed limit of Paniolo Drive is 35 miles per hour. B. Regional Roadway System Queen Kaahumanu Highway is a two-lane arterial road with unpaved shoulders. The posted speed limit for Queen Kaahumanu Highway is 55 mph. Left turn bays for southbound traffic and right turn acceleration and deceleration lanes are provided for northbound traffic at the intersection with Waikoloa Road. Mamalahoa Highway is a narrow two-lane major collector road with sharp vertical and horizontal curves. The posted speed limit for Mamalahoa Highway is 55 miles per hour. Waikoloa Road is a two- lane east-west collector road that widens to four lanes in the vicinity of Waikoloa Village. The posted speed limit is 55 miles per hour, which decreases to 35 miles per hour near Waikoloa Village. 1 Page 5-1 N PRC JECT SITE AN ISUND OF HAWAl Not to Scale c 0 0o 4Yoimea I Pacific Ocean WAIKOLOA kFFORDABLE HOUSING P OJECT ill r o 2 o ly anioloo; u rJ kO/ o rive Pua Melia R ro IIQJee Street Od aK c°o iu o Marnalahaa1A0 Source: Parsor s Brinckerhoff Quade & Douglas, 1990 ' WAIKOLOA AFFORDABLE HOUSING Figure 5-1: PROJECT MASTER PLAN Existing Roadways , For.

Existina Traffic Conditions Manual traffic counts were taken on August 7 and 8, 1990, at the intersections of Queen Kaahumanu Highway/Waikoloa Road, Waikoloa Road/Pua Melia Street/Paniolo Drive, and Mamalahoa Highway/Waikoloa Road. The morning peak hour occurs from 6:30 to 7:30 a.m., and the afternoon peak was from 3:30 to 4:30 p.m. The unsignalized intersection methodology specified in the 1985 Highway Capacity Manual evaluates gaps in the major street traffic flow and calculates capacities available for left turns from the major street to cross oncoming traffic. It also calculates capacities available for left turns from the minor street onto the major street and for right turns from the minor street onto the major street. Operating conditions at unsignalized intersections are expressed in terms of levels of service (LOS), which are designated from A to F, with LOS A representing the best operating conditions and LOS F the worst. LOS of D or better is considered to be adequate operating conditions. At present, all turning movements within the project vicinity's regional troadway system operate at LOS D or better. 5.1.2 Future Conditions Without Project Future conditions refer to the year 1997 --the projected completion period of the project. The Draft Report of Island of Hawaii Long-Range Highway Plan (Parsons Brinckerhoff, September, 1990) and a traffic study for Mauna Lani Cove (Belt Collins & Associates, October, 1989) project a 15 percent annual increase in traffic in the vicinity of Waikoloa. A. Impacts Overcapacity conditions on the regional roadway intersections as described below will occur even without the proposed affordable housing project: Page 5-3 INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 The Queen Kaahumanu Highway/Waikol a Road intersection would experience overcapacity, or LOS F, condit ons for southbound left turns from Waikoloa Road because of the incr ase in traffic volumes. The Mamalahoa Highway/Waikoloa Road intersf ction would experience LOS E conditions for the northbound left turn movements from Waikoloa Road during the p.m. peak hour. At the Waikoloa Road/Paniolo Drive/Pua Melia Street intersection, near-capacity, or LOS E, conditions would result for the northbound approach during the a.m. and p.m. peak hours. The southbound left turn movements from Pani to Drive will function at LOS E during the p.m. peak hour. Two-lane highway analysis reveals that traffic conditions on Queen Kaahumanu Highway would increase to LOS E during the a.m. and p.m. peak hours. Traffic on Mamalahoa Highway north of Waikoloa Road would increase to LOS E conditions during both peak hours. 5.1.3 Future Conditions with Project Traffic Trip generation for the proposed project is based on the following assumed land uses and square footages: 560 single-family and 840 multi-family dwelling units, a 9.2-acre park, a 5,000 square foot commercial building, and sevet al churches with a total area of 75,000 square feet. (Note: The higher total of 1,400 units was used on the traffic study to ensure a conservative analysis of traffic impacts.)

Trip Distribution/Traffic Assignment Various land uses would encourage internal trips within Waikoloa Village. Internal trips include trips between residential areas and nonresidential areas such as industrial/shopping centers, parks, and churches. The internal trips ranged from 25 percent for residential generated trips to 90 percent for trips generated by the park, commercial and church land uses. These internal trips were deducted from the total project trips to determine the number of external trips that would take place on the regional roadway system. Table 5-2 shows the external trips generated by the affordable housing project. The project traffic was distributed to and from two directions: north and south via Mamalahoa Highway and Queen Kaahumanu Highway. Table 5-2 shows the trip distribution of the generated trips for the affordable housing project. Figure 5-2 shows the traffic assignment for the generated trips for the affordable housing project.

Project Impacts 1.Local Roadway System It is assumed that Paniolo Drive will be four lanes wide and will terminate south of the project. The proposed collector roads will form the stem of a T-intersection with Paniolo Drive. At these intersections, the proposed project collector roads will be striped to provide a dedicated left-turn and a dedicated right-turn lane. Dedicated left-turn lanes will also be provided on Paniolo Drive at these collector roads. Roadway cross sections and striping will conform to the County of Hawaii Standard Details R-32, T-9 and T-10 dated September 1984. Preliminary analysis indicates that signalization will not be warranted. The total estimated project traffic volumes at full development will contribute to the existing regional transportation network, however, at or near overcapacity conditions will exist at peak periods even without the affordable housing project. Page 5-7 INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 Project generated traffic volumes for the affordable housing project were added to the 1997 future traffic volumes (without project), and the assignment is shown in Figu a 5-3. Tables 5-3 and 5-4 summarize the levels of service for future traffic conditions with and without the project.

Mitigation Measures for Regional Roadway System r For 1997 the capacity of the westbound left turn storage lane at the unsignalized intersection of Queen Kaah manu Highway and Waikoloa Road would be exceeded even without tie affordable housing project traffic. There are two alternatives that could improve operating conditions at this intersection: Alternative A: Signalization of this ir tersection would be warranted based on the Peak-Hour Volume criteria in the Federal Highway rAdministration's Manual on Uniform Traffic Control Devices (1988) even without the project traffic. Reconstruction of the Queen Kaahumanu Highway and Waikoloa Road intersection would be needed with project traffic to include double left turn bays and a single right turn lane for westbound t affic on Waikoloa Road. A two- r phase traffic signal at the Queen aahumanu Highway/Waikoloa Road intersection, with these improvements is projected to operate ratLOSDorbetterduringthea.m. and p.m. peak hours for 1997 with the proposed project. Note that this alternative is not consistent rwithcurrentStateDepartmentofTrELnsportationPolicy. r Page 5-10 r r SECTION 5 INFRASTRUCTURE SYSTEMS AND SERVICES Alternative B: Realignment of Waikoloa Road to intersect Queen Kaahumanu at the intersection of Queen Kaahumanu Highway with the Waikoloa Resort access road and construction of a grade- separated interchange at this new cross intersection. This alternative involves constructing Waikoloa Road over or under Queen Kaahumanu Highway with on-ramps and off-ramps. The State Department of Transportation prefers this alternative. The intersection of Queen Kaahumanu with Waikoloa Road will experience LOS F conditions for southbound left turns from Waikoloa Road as early as 1991; however, completion of a grade-separated interchange is not anticipated before 1995. Interim improvements,such as signalization, would provide additional capacity until an interchange is constructed. The Mamalahoa Highway/Waikoloa Road intersection may not need to be signalized with the project traffic if the grade-separated interchange is constructed. Construction of the grade separated interchange at Queen Kaahumanu Highway may divert traffic away from the Mamalahoa Highway/Waikoloa Road intersection and lower volumes by providing easier access to Queen Kaahumanu Highway. The Waikoloa Road/Paniolo Drive/Pua Melia Street intersection will experience over capacity conditions in 1997 with the project traffic. Signalization would also be warranted under Peak-Hour Volume criteria. Reconstruction and signalization of this intersection will be needed to provide sufficient capacity at this intersection. The provision of a separate eastbound left turn lane and use of a westbound through lane for traffic on Waikoloa Road would be adequate to serve the projected volumes. A three-phase traffic signal, with improvements, at this intersection would operate at LOS D or better for both a.m. and p.m. peak hours. However, a north/south collector road mauka or west of and parallel to Paniolo Drive Page 5-11 INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 is proposed. This road which will connect Paniolo Drive with Waikoloa Road west of Paniolo Drive should dive some traffic away from the Waikoloa Drive/Pua Melia Street intersection; completion of the intersection is estimated to be in 1995. With the proposed improvements describ d above, the roadway system would have sufficient capacity to serve the project traffic. The County will need to coordinate with other developers who are active in the area so that a coordinated program for regional roadway improvements can be implemented. 5.2 WATER SYSTEM The Waikoloa Water Company owns the wells, reservoirs 3nd primary transmission mains that supply potable water to Waikoloa Village. The Waikoloa Water Company's potable water wells d aw from the Waikoloa aquifer. These wells, known as Parker wells No. 4 and No. 5, ar 1 located at the 1,200 foot level nearly five miles inland from Puako Bay. Both of these Nells tap high quality water (25 ppm chloride content). In addition, a new well, Waikoloa Well No. 1, with a capE.city of 2 million gallons per day has recently been completed, and a fourth well, Waikoloa Well No. 2, is under construction. A new 1-million gallon storage tank will al o be constructed together with the fourth well. The combined pumping capacity of the three wells currently in use is 3,000 gallons per minute, or 4.3 million gallons per day and a sustained yield of 2.3 million gallons per day. The fourth well will increase the sustainable yield to 3.4 million gallons per day. Page 5-12 SECTION 5 INFRASTRUCTURE SYSTEMS AND SERVICES In addition to these potable water wells, the existing water system includes a one million gallon (mg) capacity reservoir near the wells, a transmission main connecting to a second reservoir of 1.0 mg capacity located at the 300 foot elevation above the Queen Kaahumanu Highway and the beach resort. The point of connection to the water system from the project area is an 8-inch main at Paniolo Avenue and Ho'oko Street. Impacts If as many as 1,400 units are developed, the project will have an average daily demand of approximately 560,000 gallons. The Waikoloa water system has sufficient capacity to satisfy these demands. On-site system development costs are estimated to be about $988,000. Pursuant to Section 23-84 of the Hawaii County Code regulating subdivisions, the following minimum requirements will be complied with for subdivision design and approval: Provide a water system designed to deliver water at adequate pressure and volume under peak flow and fire-flow conditions in accordance with the Water System Standards, State of Hawaii, and the Rules and Regulations of the Department of Water Supply. The water system shall include, but not be limited to, the installation of the necessary distribution pipeline, fire hydrants, and service laterals. A fee requirement of four-tenths of one percent of the estimated cost for the construction of the water system, but not less than $25.00, to cover the costs for plan review,testing, and inspection, shall be applied to the overall development costs of the project. All construction plans for on-site water system improvements are subject to review and approval by Waikoloa Water Company (the Water Company) pursuant to the Water Company's Rules and Regulations. The Water Company shall inspect and approve on-site water improvements as they Page 5-13 1 INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 are completed. 5.3 WASTEWATER At present, there is no sewer system in the immediate vicinity of the project area. The nearest sewer system is located approximately 7,000 feet southwest of the project site, and serves the commercial and multi-family areas of Wai oloa Village. The development of the subject project, as well as the development of other sites in the vicinity, will result in the need for a new sewage treatment and disposals stem. Impacts and Mitigation The existing sewer system is not available for ase by the proposed project. Preliminary analysis of the sewer system needs for the project indicates that the project will generate a total average flow of 0.5 mill on gallons per day (mgd). The proposed on-site improvements will consist primai ily of 8-inch and 12-inch gravity lines. Sewage treatment facilities will be provide off-site by Waikoloa Sanitary Sewer Company. As noted in the Project Description, the new sewage treatment plant is still in the early planning stages. One of the critical environmental issues that will require thorough analysis is the issue of effluent disposal methods and possible adverse impacts on area groundwater resources. This anc other issues will be addressed during the detailed planning work for the new ewage treatment plant. This analysis, however is beyond the scope of the present EIS. All materials and construction of on-site sewer syst m facilities and appurtenances shall be in accordance with the Department of Public Works of the County of Hawaii's"Standard Specifications for Public Work Construction," dated 1986, and the "Standard Details for Roads, Storm Drains a d Sewers," dated 1984, and all subsequent amendments and additions. Page 5-14 SECTION 5 INFRASTRUCTURE SYSTEMS AND SERVICES All construction plans for wastewater system improvements are subject to review and approval by the Waikoloa Sanitary Sewer Co. (the Sewer Company) prior to construction in accordance with the Sewer Company's rules and regulations. The Sewer Company shall inspect and approve the complete on-site improvements. 5.4 POWER AND COMMUNICATIONS An existing underground duct bank which contains a 750 MCM cable (14.47 KVY) originates from a substation located mauka of the Waikoloa Village's general store and runs along Paniolo Drive to the project site. Conduits to accommodate cable and telephone lines are also located within this same duct bank. Impacts and Mitigation A new electrical substation will be required to service the proposed and other future projects. The cost of a new electrical substation will be in the range of $1 million. Project power and communications development costs are estimated at approximately $1.46 million, assuming that these utility systems will be located underground. The increased demand for electrical power will probably be met by oil-fired generating facilities. Geothermal produced electricity may also be a source of energy for the project. Energy conservation measures should be utilized to help reduce the project's energy requirements. These measures should include: (1) engineering and architectural designs that stress energy conservation, (2) the installation of energy- saving devices such as solar water heating systems, energy efficient refrigeration, and energy efficient lighting. 5.5 SOLID WASTE The proposed project will generate in the range of 10 tons of solid waste per day at build- out, assuming 1,200 to 1,400 units and 3+ people per unit. Page 5-15 INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 Currently,the solid waste disposal system for West Hawaii has some significant problems. At best, the existing landfill at Kealakehe can be utilized for another two years. The County is currently developing plans on an expedited basis for a new sanitary landfill project, to be located some miles south of the project s te. Existing solid waste transfer stations at Puako and at Kot ala are currently operating near capacity. A new solid waste transfer station is being planned at Waikoloa. Impacts and Mitigation The proposed project at build-out will generate a significant volume of solid waste which will add to the volumes of refuse being pr duced by other residential and resort developments in West Hawaii. A new solid waste transfer station will probably be needed to service the project and oth gr area developments. Families living in the County's "affordable housing" project at Waikoloa should be encouraged to participate in waste recycling anc other waste volume reduction programs. 5.6 POLICE AND FIRE PROTECTION 5.6.1 Police Protection The Waimea Police Station provides police protection to a 680 square mile area which includes South Kohala. There are, at present, 4 patrolmen assigned to each 8-hour shift. According to current staffing expansion plans at the Wai ea Station, an additional 10 to 12 more people are expected to help meet the district's immediate needs. Impacts and Mitigation In order to meet the proposed project's police protection requirements as well as those of the growing regional population, byte year 2000, a new Waikoloa Substation has been recommended to be in sery ce (Captain Lawrence Mahuna, October 31, 1990). Page 5-16 SECTION 5 INFRASTRUCTURE SYSTEMS AND SERVICES 5.6.2 Fire Protection The Mauna Lani Fire Substation, located 10 miles from Waikoloa, provides fire protection services to an area that stretches from Mahukona to Kona Village, including the project area. Currently, 5 firefighters are assigned to each of three weekly shifts. Impacts and Mitigation In order to respond to the proposed project's fire protection requirements as well as those of the growing regional population, the County of Hawaii is planning a new fire station in the Waikoloa area (telecon with Mauna Lani Fire Station representative, October 1990). The schedule for this new facility has not yet been set. In the interim, the project will be served by the Mauna Lani fire substation. 5.7 MEDICAL FACILITIES The State's Kona Hospital located in Kealakekua, provides medical and health care services to the Waikoloa area. This hospital's service area covers Kohala to Hawaiian Oceanview Estates. It is a 75-bed acute care facility which provides a range of services including long-term care, skilled and interim nursing care, obstetrical, pediatrics, laboratory, cat scan, physio- and occupational therapy, chemotherapy, and a 24-hour emergency room. Kona Hospital in currently in the process of expanding its facilities and services to include a surgical suite and new recovery room. Two other facilities, Kohala Hospital in Kapaau and Lucy Enriquez out-patient services in Kamuela, also provide medical services to the project area. Impacts and Mitigation The proposed development will result in an increased population in Waikoloa Village that will require the full range of medical and health care services. The expansion of the Kona Hospital will help meet some of the health care needs of this new residential community. A West Hawaii Regional Health Center is currently being planned in the Kailua-Kona area. North Hawaii Hospital in Kamuela which is a joint-venture between government and private enterprise, is in the process of Page 5-17 t i INFRASTRUCTURE SYSTEMS AND SERVICES SECTION 5 i development as a full-service, primary care facility i 5.8 SCHOOLS At present, Waimea Elementary, Waimea Intermediate and Honokaa High Schools iincludeWaikoloaVillageintheireducationalservicesareaBothWaimeaElementaryand Intermediate Schools, and Honokaa High School are oper ting beyond capacity and have severe shortages of classrooms, according to the State's Superintendent of Education August, 1990). i Impacts and Mitigation The DOE schools cannot accommodate the large additional enrollment growth i which will result from the Waikoloa Affordable How ing project and other Waikoloa projects until additional classrooms are built. Projected enrollment demand by the project is summarized as follows: Projected School Grades Students Waimea Elementary K thru 5 425-475 Waimea Intermediate 6 thru 8 175-225 i Honokaa High 9 thru 12 275-325 NOTE: Projections are based on a total Of 1,400 dwelling units. i The Department of Education is evaluating the offer of approximately 36 acres of ilandfromtheWaikoloalandCompanyforuseasaschoolsiteandcombined community recreation center.

The park, which is under construction, is scheduled to be open to the public in September 1991. It is planned to include a soccer field, softball diamond, and playground equipment. Impacts and Mitigation The proposed affordable housing development will provide a variety of recreational facilities on the project site: a community park of approximately 9 acres located at the entrance of the development, and a neighborhood park of 7 acres at the makai end of the development. The proposed 36-acre public school site adjacent to the southeast boundary of the proposed project may also offer additional community recreational facilities, such as ballfields. 1 Page 5-19 1 1 1 SECTION 6 1 1 1 1 1 1 1 1 1 1 1 1 1 ALTERNATIVES TO THE PROPOSED ACTION 1 1 SECTION 6 ALTERNATIVES TO THE PROPOSED ACTION 6.0 OVERVIEW The alternatives considered for this evaluation include the "no project" alternative, income mix alternatives and economic range of housing units, and alternative land use concepts. Because the original transfer of this property from Transcontinental Development Company to the County of Hawaii was intended specifically for the purpose of increasing the badly needed affordable housing supply in West Hawaii, there was no doubt that the focus of the County's use of this property was for the development of housing. i6.1 NO ACTION The "no action" alternative would result in continuation of existing conditions for the Waikoloa project site. The site would most likely continue in its undeveloped condition. However, as surrounding development occurs as part of the overall Waikoloa Village expansion, other uses of this site could occur. Advantages of the "no action" alternative are few. These advantages include: no further expenditures of resources by public and private agencies; continued non-use of the site; and no adverse impacts on the project site generated by development. The primary disadvantage of this no-project alternative would be the absence of a planned residential community with a unique mix of affordable housing opportunities to suit lower and low-to-moderate income families. Additionally, losses resulting from this alternative would include lost housing and employment opportunities, as well as lost tax revenues for County and State governments. 6.2 SITE SELECTION The initial site selection process conducted by Transcontinental Development Company TDC, the original land owner of the site), involved initially identifying a general area of approximately 580 acres for evaluation and analysis to determine suitability for residential development. The purpose of this site study was to help Transcontinental locate a large enough land area to accommodate a planned affordable residential community. Page 6-1 1 ALTERNATIVES TO THE PROPOSED ACTION SECTION 6 To determine the best possible location for the affordable housing project site, the 580-acre study area's physical characteristics were asse ed--topography, soils, climate, flora, fauna, archaeological sites, natural hazards, and existing infrastructure. As part of the analysis, site constraints were generally identified and developable areas were delineated. The result of the analysis provided for the selection of the northern portion or most developable area of the property for the Coun 's housing project. Even in this selected area, some development constrai is exist. Thus, additional land was allocated for the recommended site. A total of 340 acres was set aside, of which 25 acres encompass potential flood plains, 10 acres are steep lands, and 5 acres are for a sewage treatment site. The total net area for the recommended site was thus 300 acres. 6.3 ECONOMIC MIX OF HOUSING UNITS Maintaining the project's overall economic feasibility whilE truly providing all of the housing units at affordable rent and sales price levels has been one of the project's major objectives. To theoretically achieve this balance betweE n the County's social objectives and economic viability, numerous cash flow analyses were conducted to reflect different scenarios of economic mixes of types of housing units. Each of the cash flow analyses contained different sets of assumptions regarding varying per square foot building construction costs, dwelling unit sizes, and numbers of units assigned to each intended target group of buyers. One scenario indicated that total revenues from the sale of 1,000 units would be $129 million, while total development costs (including buildinc construction, subdivision or on- site development, backbone infrastructure, sales/processing fees, indirect costs for design, management, loan points, contingencies at 150A, and developer's profit at 5% of revenues) are $132 million. At an annual deficit financing rate of 12%, the deficit after financing will be $17 million. The conclusion to this series of analyses and evaluations was that, to a certain extent, modification of certain subdivision standards may result in significant cost savings, and Page 6-2 SECTION 6 ALTERNATIVES TO THE PROPOSED ACTION may further result in more affordable housing. These modifications need, however, to 1 ensure that such cost-saving methods, (1) will not result in health and safety risks; (2) will not result in significant added post-construction maintenance costs for the County and/or for the residents; (3) will not have an adverse visual impact; and, (4) will clearly result in a greater number of affordable houses and/or lower prices for some or all of the homes. 6.4 LAND USES WITHIN THE AFFORDABLE HOUSING PROJECT Various alternative development concepts were explored during the master plan preparation process. This process involved identification of the opportunities and constraints, which provided the basis for the environmental concept (Figure 6-1). Developable areas excluded steep slopes, primary ridgeline, and major drainageways. These constraints added a new dimension to the overall development concept. The analysis revealed opportunities to enhance the development pattern by incorporating unbuildable areas as buffer areas. Constraints were thus turned into amenities. The developable areas were grouped into four different general types: A) Land type characterized by having soils and vegetation which provide high visual and drainage absorption. B) Lands that may be characterized as well-drained sloping uplands. IC) Enclaves, or valley-like topographic features. ID) Areas found in the western or makai end of the site -- these are areas of concentrated drainage. The different site types presented land use planning and development opportunities in the general siting within the project site of the internal collector roadway system, housing sites, neighborhood and community parks, and church/commercial areas.

Provide at least one community park located near Paniolo Drive so that it would be utilized by not only the County project residents, but by adjacent neighborhoods as well. Provide an area for "church/convenience commercial' uses that will service the project as well as adjacent neighborhoods. The Master Land Use Plan was developed based on these guidelines and criteria. Page 6-5 SECTION 7 1 1 RELATIONSHIP TO LAND USE PLANS AND POLICIES 1 SECTION 7 RELATIONSHIP TO LAND USE PLANS AND POLICIES 7.1 THE HAWAII STATE PLAN The Hawaii State Plan represents a guide for the future of Hawaii. The State Plan sets forth a broad range of goals, objectives, and policies to serve as guidelines for growth and development of the State and establishes a coordination system between the State and County agencies. Chapter 226, Hawaii Revised Statutes, as amended, 1986, states the following purpose of the State Plan: it) shall serve as a guide for the future long-range development of the State; identify the goals, objectives, policies, and priorities for the State of Hawaii; provide the basis for determining priorities and allocating limited resources, such as public funds, services, manpower, land, energy, water, and other resources; improve coordination of state and county plans, policies, programs, projects, and regulatory activities; and to establish a system for a plan formulation and program coordination to provide for an integration of all major state and county activities." Chapter 226-1: Findings and Purpose, FIRS) The proposed project is generally consistent with objectives and policies of the Hawaii State Plan. The following sections analyze relevant goals, objectives, policies and guidelines of the State Plan relative to the proposed project. A. Section 226-5 Objectives and Policies for Population The Waikoloa Affordable Housing Project will contribute to the distribution of future growth expectations of the West Hawaii region by providing a well managed community offering a mix of housing types and community support facilities. B. Section 226-6 Objectives and Policies for the Economy In General Development of this project will directly benefit the economy in terms of construction, commercial/retail, public institutional, and real estate opportunities. Page 7-1 1 RELATIONSHIP TO LAND USE PLANS AND POLICIES SECTION 7 C. Section 226-12 Ob'ectives and Policies fc r the Physical Environment - Scenic Natural Beauty, and Historic Resou ces The project will be designed to promote vie s of the surrounding peaks of Mauna Kea to the east, the Kohala Mountai s to the north, and the Kohala coastline to the west. Southeast of the project site are the rolling hills of Waikoloa Village. The south slope of Halea ala Crater on Maui is visible on a clear day. D. Section 226-13 Ob'ectives and Policies fortthe Ph sical Environment- Land,, Air and Water Quality Air quality of the Waikoloa Village area will be impacted by traffic generated from the proposed project and surrounding neighborhoods. Water quality impacts will be minimal due to implementation of an effective potable water system and drainage system. In some areas of the project site, grading of the land will be needed for roadways and subdivision development. This action will change some of the natural slopes of the site. E. Section 226-15 Obiectives and Policies fo Facility Systems - Solid and Liquid Wastes Wastewater generated from this project will utilize a new sewage treatment plant which will be provided off-site by the Waikoloa Sanitary Sewer Company. Solid waste will be disposed f at the proposed new West Hawaii Sanitary Landfill. F. Section 226-16 Ob'ectives and Policies for Facilitv S stems - Water The proposed project is located within the 3ervice area of Waikoloa Water Company, and will utilize the potable water upplied by the wells tapped by this Company. Page 7-2 SECTION 7 RELATIONSHIP TO LAND USE PLANS AND POLICIES G. Section 226-17 Objectives and Policies for Facility Systems - Transportation The proposed project will add to traffic volumes around the project site. Measures to mitigate the increased traffic include roadway improvements to off-site roadways and intersections. H. Section 226-18 Objectives and Policies for Facility Systems - Energy/Telecommunications Energy and telecommunication facilities necessary for the development of the Waikoloa Affordable Housing Project will be planned and coordinated with the appropriate agencies and public utilities. Energy conservation and the utilization of energy-saving devices will be encouraged through guidelines for designers and developers as well as through homeowner information and orientation programs provided by the County. I. Section 226-19 Objectives and Policies for Socio-Cultural Advancement - Housing The proposed project is designed to accommodate a variety of housing types suited to families with incomes ranging from below 50% of the median income to the Hula Mae qualifying levels. This income range is representative of the general worker population in West Hawaii. The Waikoloa Affordable Housing Project will be consistent with this section by offering a mix of housing types (including gap-group and assisted housing), and costs to suit the needs of a large portion of the housing market. Integral planning of the overall development will provide necessary support facilities for these housing areas. J.Section 226-20 Objectives and Policies for Socio-Cultural Advancement - Health Medical and health care facilities are currently located in Kapaau (North Kohala), Kealakekua (Kona), and Kamuela, with emergency services provided by the Kohala Hospital and the Kona Hospital. There are Page 7-3 RELATIONSHIP TO LAND USE PLANS AND POLICIES SECTION 7 anticipated increases of medical and health care services and facilities for West Hawaii as the development of the re ion continues. In the planning stages is a North Hawaii Hospital located in Kamuela. This new 50-60 bed hospital will be a joint venture project be een government and private enterprise, and is planned as a full-se ice facility. Additionally, the abundance of recreational facilities anticipated within the project area will promote "wellness" through physical and r iental health. K. Section 226-21 Obiectives and Policies foi Socio-Cultural Advancement - Education The Waikoloa Land Company is in the process of donating a parcel of land to the State Department of Education fortthe development of a school site to service the Waikoloa Affordable Housing project and the surrounding community. The site is adjacent to the southeastern boundary of the project site. Close cooperation with the E epartment of Education will be maintained to ensure adequate provision f educational services. L.Section 226-23 Ob'ectives and Policies foi Socio-Cultural Advancement - Leisure Recreational facilities will be provided wit iin the development offering a variety of activities including a neighborhood park, ballfields, and recreation centers. These facilities, as well as the adjacent school site provide an abundant amount of open space within the project site. M. Section 226-104 Population Growth and Larid Resources Priority Guidelines Development of the Waikoloa Affordable F ousing project will result in the permanent loss of open space as it exists, iowever, the master plan of the project is designed with open space areas including parks. The proposed urban use of the land is consistent with 1he State and County land use policies for this site. Page 7-4 SECTION 7 RELATIONSHIP TO LAND USE PLANS AND POLICIES The project site was not determined to be environmentally critical in the areas of archaeology,flora, and fauna. Any environmental impacts resulting from development will be mitigated where possible. N. Section 226-106 Affordable Housing Priority Guidelines for the Provision of Affordable Housing The proposed project will incorporate a mix of housing types to include gap group and assisted housing. While other residential development projects attempt to offer a mix of market rate and affordable housing units, the Waikoloa Affordable Housing project is intended to offer all of its units at rental and sales price levels that will be affordable to families in West Hawaii that would otherwise be priced out of the housing market. 7.2 STATE FUNCTIONAL PLAN The Hawaii State Plan is used as the primary tool for directing the planning process for Hawaii's long-term and short-term goals. Functional plans, created as extensions of the State Plan, are prepared by the appropriate State agencies to specify objectives, policies, and implementation actions of their respective concerns. These plans were reviewed and evaluated with regard to the proposed project. The following are descriptions of functional plans applicable to the proposed project. 7.2.1 Education Plan This functional plan relates to educational functions, school systems, goals and growth. Topics within the plan are organized under four categories: personal skills and knowledge; employability and economy; social and natural resources; and educational support services. Development of the Waikoloa Affordable Housing project, as well as neighboring communities, will result in an increased demand for educational facilities for the West Hawaii region. The school site adjacent to the proposed project may include a facility that will accommodate grades K through 8. Page 7-5 RELATIONSHIP TO LAND USE PLANS AND POLICIES SECTION 7 7.2.2 Housing Plan This functional plan, managed by the Housing Finance nd Development Corporation, deals with orderly development of housing and expanded housing opportunities for Hawaii's people. Objectives of the functional plan are to: develop greater opportunities for Hawaii's peopla to secure reasonably priced, safe, sanitary, liveable homes located in suitable environments that satisfactorily accommodate the needs and desires of families and individuals'; assist the orderly development of residential area 3 sensitive to community needs and other land uses." An innovative concept of the proposed project is to offer a wide range of housing types with varying costs. The Waikoloa Affordable Housing p oject will address the need for affordable housing by providing homeownership and re tal opportunities to families and individuals with varied income levels. For-sale units will be available to families whose income levels are too low for conventional home buying methods. Housing within the development will include approximately 1,200 units. 7.2.3 Health Plan The primary purpose of the State Health Plan is to servo as a guide for State and County agencies and the private sector in outlining environment related objectives and health care objectives for Hawaii. This plan, undei the jurisdiction of the State Department of Health (DOH), focuses on: "preventing disease and promoting healthful life styles and environmental conditions; ensuring and promoting appropriate provisions and access to health care; protecting society from poten ial dangers; and enhancing the quality of air, land and water resources and preventing 3nvironmental degradation." Currently, the State's Kona Hospital, located in Kealakek ia, provides medical and health care services to the Waikoloa area. Two other facilities, Kohala Hospital in Kapaau and the Lucy Enriquez out-patient services in Kamuela, curr ntly provide additional medical Page 7-6 now M MMA M r mom larnlne P.

Your comments on the archaeological survey have been noted. However, please refer to the comment letter from the Department of Land and Natural Resources DLNR), dated January 10, 1991. DLNR states that " we agree that construction of this planned housing development is likely to have " no effect" on historic sites." On the subject of the " Kamakoa Gulch iloodplain drainage study," we agree that such a study is an important element in the planning process. However, the detailed drainage study that is needed for Kamakoa Gulch cannot be undertaken until detailed topographic data are available, and until an overall strategy for drainage management has been resolved for the several developments that are being planned in this area of Waikoloa. At this time, both the topographic data and the drainage management discussion are in process. Thus, conclusions cannot yet be documented in the Final EIS.

We must emphasize that the schools cannot accommodate the additional enrollment until additional classrooms are built. Honoksa High already has limited apace for expansion and also requires the replacement of old wooden buildings.

The proposed development is situated above the Department' s Underground Injection Control( UIC) line. Land areas located above the UIC line are generally considered to contain underground sources of drinking water These areas should therefore be protected against all sources of groundwater contamination. 3. According to the DEIS, drywells will be used for the disposal of surface water runoff. Since these drywalls would be classified as Injection wells, they must comply with the Department' s Administrative Rules, Title 11, Chapter 23,' Underground Injection Control' Chapter 23 requires UIC permits for the construction and operation of all Injection wells. 7 r Lorraine R.

We have reviewed the materiels submitted by the State of Hawaii- Office of Environmental Quality Control and have the following comments. We concur that the archaeological survey adequately demonstrates the probable absence of historic site@ in the 279 acre planned housing development and that the historic literature review depicts the area an having been marginal for major subsistence and residential activities. These results are also adequately addressed within the main text of the EIS. We agree that construction of this planned housing development is likely to have no effect" on historic mites. We would, however, ask that one addition be made to the main text of the EIS where Historic and Archaeological Resources are discussed. Despite negative survey results and an overall low probability of finding historic remains, it is always possible that some, including human burials, could be uncovered during construction. Please ask the Applicant to add a statement which acknowledges thin possibility and Commits then to halting construction in the immediate vicinity of an inadvertent discovery. r Laraine R.

The principal reviewer was Mark Underwood. Please contact him at 808) 541- 2657 if you have any questions. Section 2. 7. 1. A description of the wastewater treatment was not given, nor is a reference given where this can be looked up within the report. Where is the treatment and sewerage discharge? What will the addition of this new development be on the wastewater treatment? Will the addition of this proposed increase in sewerage affect the treatment facility? Doe. this comply to EPA standards, both currently and with the additional development?Section 2. 7. 2. Several unsubstantiated facts were given. It was stated that 100, 000 million gallons of ground water lies stored in the aquifer that supplies the water for Waikoloa Village. Is this water stagnant? Is this ell freshwater or brackish water' What is its source? The other troublesome star emenr is that 7 0 to 5. 0 Mgal/ d is flowing through the aquifer In the vicinity of the well. Do these figures refer to flow per unit width ( i a per mile) of aquifer? Section 2 7. 7, 7 7 and 7 9 It is stated that 58, 000 acres produces about 2, 000 f. of runoff I. trl, ft. b.. through Kaneko. e. teh. When does this occur? During a typical day, or during a small shower, a large rainstorm? Is it only the 58, 000 acne that produces 12, 000 eta of runoff, or is this the amount that the whole watershed produces? A flow of 12, 000 efs is very substantial.Section 9. The basic fundamental, of streamflew, as relevant to this specific area, appear to be poorly understood.

Only 46 species of vascular plants were found growing on the site, an extremely low number for an area of this size. Of these, 40 ( 87%) were exotic weeds or deliberately introduced plants, and 6 ( 13%) native, or presumed- native plants. None of the species found on the site are officially listed as endangered or threatened; nor are any species proposed or candidate for such status. SURVEY METHODS A walk- through method was used for this survey, with plants identified on sight. Plants that could not be positively identified were collected for later determination by comparison with known specimens in the herbarium and reference to standard taxonomic literature. Taxonomy of ferns is based on Wagner and Wagner ( 1987). Taxonomy and nomenclature of the flowering plants follows Wagner et al. ( in press).

RECOMMENDATIONS It is suggested that native plants be used in future landscaping of the site. A number are both attractive and adapted to the present climate, while others would thrive with common landscape practices. Some control should be exercised in bringing in exotic species. A number of undesirable weedy spe- cies ( toxic, invasive, or both) could potentially escape from cultivation and become serious problems in the future. Examples are a cactoid euphorbia perhaps Euphorbia lactea) and Aloe, both of which were seen in rubbish piles along the roadside. The presence of exploded ordnance on the site suggests that unexploded ordnance may be present, though none was seen during the survey. Another problem is that the ash- soil in the northeastern half of the site appears to be subject to rapid and severe erosion. It should be landscaped as soon as possible after disturbance. This would also mitigate problems with dust. 4 5 MM mom rr r r err r i r SPECIES LIST d A list of all the vascular plants found on the site follows.

Measures to mitigate these impacts are suggested where possible and appropriate.1. 0 AMBIENT AIR QUALITY STANDARDS Ambient concentrations of air pollution are regulated by both national and state ambient air quality standards ( AAQS). National AAQS are specified in Section 40, Part 50 of the Code of Federal Regulations ( CFR), while State of Hawaii Chapter 11- 59 of the Hawaii Administrative Rules. Table 1 summarizes both the national and the state AAQS that are specified In the cited documents. As indicated In the table, AAQS have been established for six air pollutants. These regulated air pollutants include: particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone and lead. National AAQS are stated in terms Si 1 We IM M M NNW WAR ow M so IM A a* low of primary and secondary standards.

As indicated in Table 2, the only existing monitoring data emissions which could directly result in short- term air quality anywhere near the project site consist of sulfur dioxide and impacts during the construction phase: ( 1) fugitive dust from particulate measurements that were made about 70 miles to the south vehicle movement and site excavation; and ( 2) exhaust emissions at Realakekua during 1985 and 1986.

Twenty- four hour average particulate concentrations ranged from 4 to 28 pg/ ml; no violations of the state AAQS were measured.

Worst- case emission and meteorological dispersion conditions typically occur during the morning hours at many locations. Thus, For this project, three scenarios were selected for the carbon even though traffic volumes may be higher in the afternoon than in monoxide modeling study: year 1990 with present conditions, year the morning, worst- case air pollution concentrations may occur 1997 without the project, and year 1997 assuming the project is during the morning. To ensure that worst- case concentrations were built and complete. To begin the modeling study, critical receptor identified, both morning and afternoon peak traffic periods were areas in the vicinity of the project were identified for analysis. studied. Generally speaking, roadway intersections are the primary concern because of traffic congestion and because of the increase in vehicular emissions associated with traffic queuing. For this The EPA computer model MOBILE4 [ 8) was used to calculate vehicular study, the key intersections identified in the traffic study [ 7] carbon monoxide emissions were also selected for air quality analysis. These include: Queen the key inputs to MOBILE4 is vehicle mix.

If all refuse is landfilled, the only air pollution emissions associated with solid waste disposal ( assuming problems similar to 6. 2 Electrical Demand those which currently exist at the Kailua Landfill are avoided) will be due to exhaust fumes and fugitive dust from trucks and The proposed project will also cause indirect emissions from power heavy equipment used to place the refuse in the landfill.

BONK UNIVERSITY OF HAWAII AT HILO prepared for BELT , COLLINS ASSOCIATES i i r Hilo , Hawaii December, 1988 _ r 1 INTRODUCTION During the early part of I,ay , 1903 this writer was contacted and asked to submit a proposal for an archaeological reconnaissance survey and report for a parcel of land in the Waikoloa area of Hawaii . After examining the particulars re- garding area , access , etc . a proposal was drafted and sent to Belt , Collins and Associates of Ilonolulu . Early in July I re- ceived authorization to proceed with the project and the fol - lowing pages of this report provide the results of the inves- t tigation and the recommendations that result from that re- search . Prior to completion of this report a Preliminary letter statement of my findings was communicated to Belt , Collins and associates , to pertinent State and County offices , and to the Director of Planning at llaikoloa . r r 1 r r r 1 r 1 r r AREA The area surveyed and reported on in this report is in the ahupua 'a of Waikoloa , South Kohala D strict, on the island of Hawaii . It consists of a 580 acre par el of land at the north end of Waikoloa Village (See Figur 1 . ) In addition , it may be further identified through its Ta 11ap Key : 6-8-02 : 26 , which places its location to the north aid west of Paniolo Drive (See Figure 2 . ) The general shape of the project rea is slightly long- er in its north-south axis than in its a st-west direction al - though there is a slight bulge in the ce ter of its eastern margin . A rough dirt road extends northw rd from the end of Paniolo Drive and so forms the 60001 fee eastern boundary of the plot. The northern border follows th center of Kamakoa Gulch for approximately 4600 feet , where s a smaller , unnamed gulch is at the southern perimeter . Here the study area is at its narrowest , with only about 4000 feet separating the south- east corner of the parcel from that of t e southwest. The 5000 feet of the western borderline curves slightly in a northwest direction thereby allowing for a greater width in the northern portion of the parcel in comparison to tat of the southern portion of the plot . The surface gradient within the tract exhibits a gener- al downward slope toward the west. In the north the terrain drops some 213 feet from east to west , with the lowest eleva- tion , some 567 feet above sea level , recorded in the northwest corner of the project area . In contrast, a drop of only 135± feet was noted for the southern margin . lhe highest points within the tract are usually along or jus t within the eastern border. In the northeast we recorded 780 feet above sea lev- el , in the southeast approximately 785 feet, and at a point roughly one-third of the distance north cf the southeast cor- ner we recorded the highest elevation in the parcel at 893 feet above sea level . The region in and around Waikoloa Village is noted for Its savanna-like quality of the physical environment. Rainfall is light , probably no more than 35 to 40 inches a year. As a result course grasses with scattered scr b tree growth , most often keawe , dominate within the ecosystem. In addition , there are numerous days during the year when t e wind is quite strong and sometimes gusty. The project area is very typical of that just described for the broader region (See Title Page illus- tration and Figures 3-6. ) The ground surface varies somewhal from place to place 2 wnoHAWI- a1.V.V aV. iMahukona Harbor -- ISLAND OF H...H Lapakahl Slate Historic Park s n i Kohals Mountains OffHO Ka.alhae Harborer KAWAIHAE- awr.ss '• WAIMEN H,P n Beach Stale Park —) Walmaa-KoMla Airport If WAIKOLOA VILLAGE o 2 a r a Maws Kea. 1I r It Keshole Airport—= a••e Honokohsu Harbor KAILUA-KONA 1 CEAUHOU — I 1j`i l I KEALAKEKUA X I I Mau a Loa I 7 1 fff{{{ Flynn I REGIONAL MAP 3 Kohala and Kona, Hawaii Scale: 1 inch 900 feet v. f. r' 1 - _ r ' •'• ;.{' PROJECT AREA 580 Acres) L. a - w: may 1 Figure 2 f1 ' j ,:- .,/ l` I . \ Waikoloa Village and Project Area III Il p IXIItliir 111 II II IINN' II I INIINI1I II,RIiqU.!.IIII MIIIH III IIIIV II I iIM IIUIII!'

The southern half of the p oject area includes places where the ground surface drops mo a precipitously as well as where rock outcroppings hinder s eady novement. Fur- thermore , localized tracts covered with a 'a resulted in dif- ficulty of movement and a reasonable tim for examination . More difficult yet were the 'a 'a tracts overed by grass . Here both footing as well as sight were limit d. One result was the sharp increase in time required to exam ne a particular sec- tion of the study area . On numerous occa ions while in the field this writer struggled and eventual y fell or stumbled because of the terrain . 7 r METHODOLOGY This report is the end product of a field investiga- tion commonly referred to as a reconnaissance survey . Visual observation and record keeping while walking through an area to be investigated is normally part of the methodology used in the field for this type of survey . In this case notes were recorded in a field book and photographs were taken in both black and white and color film. luny times when cultural data or material is encountered the survey leads to addition- 1 al stages of investigation . When this takes place it usually is the result of recommendations included as part of the re- connaissance survey. For this investigation the field survey was carried out by myself with the aid of my son , Ken , who quite often accompanies me in the field . Approximately 115 hours went into the field portion of this survey . Eight transects in an east-west/west-east direction were first carried out, followed by four transects in a south-north/north-south direction . With this amount of detailed coverage of the area we feel quite confident that no portion of the study area was overlooked. i 1 1 r r FINDINGS AND RECOMMENDATIONS r Throughout the field examination we found nothing to indicate past use of the project area of er than some scat- rteredshrapnelfragmentsindicativeofuseasamilitary target area in the recent past. However, these fragments were quite limited and therefore it is surmised that this rusewasofanaccidentalorsporadicnatureratherthan one of a regular occurrence . Perhaps the event that led to the presence of these metal fragments in this area dates to the period of World War II when large nu bers of U . S . serv- icemen were based and trained at Waimea and used the sur- rounding region for training purposes . In conclusion , and as a result that we found noth- ing of prehistoric or historic significance within the area investigated , we therefore nust recommenc that no further archaeological work be required . In adds ion , it is further recommended that, based on the above , an land transforma- tion would not be archaeologically detri ental and there- fore can proceed . r r r r r r 9 1 i ADDENDUM The following additional remarks to my report of December 1988 should be viewed as a form of clarification and addition . This is so as to add to what has originally been set down as well as to illuminate that which may have been questionable. The first two figures (maps ) are both descriptive and interrelated , in that the study area is to be found north of Waikoloa Village and west of the northernmost end of Paniolo Drive. This road is paved and completed for somewhat less than one-third the distance along the east border of the study area . Beyond that an unpaved "jeep" trail extends along the east border and beyond the northern limits of the study area . An additional map , originally drafted by Engineers Surveyors Hawaii , Inc. is included in this supplement so as to illustrate the lay of the land. As one can see from a perusal of this map only two gullies are found and these deli - neate the southern and northern ends of the area examined . Nowhere were we restricted from examining the ground surface although the banks of the gullies are somewhat more difficult to view , as was a region in the south- west where thin slabs of clinker 'a 'a , partially covered by grass , produced unsure foot- ing . This portion of the area examined also has the greatest Incidence of surface declivity , hence the need for more time in coverage . No recorded lava flows are within the area- examined. A brownish patination on the rock surface also supports a mini - mal age of more than 200 years for the flow. How much beyond this time , however, is fathomless . The northern half of the tract was walked over more readily and with less difficulty, for all but the immediate locale of Kamakoa gulch . The north- ern portion of the area examined exhibits no steep slopes and very little rough ground surface. In terms of climate and vegetat8on th8 land is quite arid .Mean annual temperature is about 24 C ( 75 F ) and mean annual rainfall is a little over 250 m (about 10 in . ) If we use the Koeppen classification system we have to refer to this area as Hot Desert (BWh . ) The Waikoloa Village area is noted for its windy conditions .' Land .breezes tend to sweep across this open region , predomi - nantly from the northeast, but occasionally during the winter months there is a shift an-d they then blow from the southwest. 1 With this reversal of wind pattern com s most of the moistureduringthewintermonths . The subject area falls within McE downey ' s VegetationZoneIII (1983 : 410) . Grasses form th dominant vegetationinterspersedwithscatteredstandsofiawe. Buffelgrass and pili predominate over other grasses , a d shrubs are seen moreoftenthaninlowerelevations . Fount in grass is seen here and there and seems to be gaining in s gnificance over time . In the northern half of the study area , soils are shallowaridsolsoftheKawaihaeseries ( KYC) . Well drained , gritty,and stony , they tend to be moderately eroded by wind and water.Formation is from aeolian fine sand anc silt , although weather- ing of volcanic ash is also part of the formative process . An upper horizon of very fine sandy loam overlays loam or silt loams with a weak medium and/or coarse prismatic structure. Calcium carbonate collections are seen as coatings on rocksUSDASoilConservationService ; 1973 : 26 . ) Hard pahoehoe bed-rock is at a depth of between 20 to 40 inches , permeability ismoderateandrunoffismedium. Roots usually penetrate to bed- rock. This soil is used mostly for pasture although no cattle were seen in the area during the field investigation .

Slope in- creases here with a range of between 10 and 15 percent . Betweenlavaoutcropsandinthecracksofthelava , the soil extends to a depth of 5 to 20 inches . Erosion here is slight .USDA Soil Conservation Service, 1973 : 52 . ) The prehistoric land use pattern in the Waimea-Waikoloa area was originally subsistence horticulture and a subsistence marine exploitation . By the later half of the 16th century ,we see changes in this pattern with an Increase , through time , of what I have called a "subsistence-su port" economy . This reaches its peak in the late prehistori of the second half ofthe13thcentury ( Bonk , 1985 : 6 . ) As fo eign ships increasedinnumbersatKawaihae , in the early hi toric period , we see a further development to a "subsistence trade" economy for theenvironsof 'Waimea . Through the 19th c ntury , cattle becameagreaterandmoreimportantpartoftheconomicbase,the transporting of products , and a money-based economic system gradually substituted for that of a subsistence base. As was mentioned previously ( Bonk , 1985 : 6 ) these cultural changes went hand in hand with a relate4i environmental evolu-tion in the form of botanical and zoolo 1cal change. Subse- quently , this had an effect on the land surface. Exotic animals 2 and plants substituted for endemic varieties , which furthermore set off a new ecological movement that changed the physical as well as the cultural environment. The above cultural -ecological overview, although origi - nally written with respect to the Waimea area , has implica- tions as well for Waikoloa . It was Soehren (1980) who pointed out that: At the Mahele of 1848, the land, Waikoloa , was awarded to George Huen Davis , son of Isaac Davis , the English companion and advisor to Kamehameha I . " The viewing of a present day tax map tends to over state this award to Davis by the king . Because of the nature of the land many "commonly regarded" Waikoloa not "as an ahupua 'a but as "an 'ili 'aina of Waimea. " Soehren goes on to say that Waikoloa ' gargantuan size is in inverse proportion to its value to the ancient Hawaiian economy. " Because of the availability of water and the productive soils of the Waimea area , the development depicted previously (Bonk , 1985 ) allowed Waimea to become the "food-basket" of South Kohala . It became more significant as time passed and the surrounding areas became more subordinate to its power. This could well account for the interpretation of Waikoloa as an 'ili 'aina. It could also be the reason for its large size, for value is not necessarily based upon size alone , nor size of great value. In fact we might better evaluate on the basis of other criteria , such as the effectiveness of cultural and population support criteria. This discussion leads one to sum up by quoting Soehren (1984) who says , " In aboriginal times , before cattle, these lands (Waikoloa ) were marginal to the Hawaiian economy , serving as a reservoir of material products such as pili grass and birds . " Certainly, without an assured source of water, as the people of Waimea provided through the building of their extensive irrigation system, the midlands of Waikoloa were not able to support horticulture. A yearly rainfall of 10 inches and a soil base inherent with limitations of a cultural nature would not allow permanent settlement at the time. This can account for the paucity of archaeological remains in the mid- lands of Waikoloa and explains as well why we found nothing of prehistoric cultural significance in the region that we scru- tinized. As cultural evolution proceeds , however. cultural transformation can substitute for the lack of use in the past. Today, the village of Waikoloa , is fast growing . However, only the cultural "umbilical cords" of piped water, financial support from elsewhere, speedy transportation , and a national -interna- tional economic/cultural base is this possible at this time . Marine exploitation was more readily available for the coastal inhabitants of Waikoloa and its neighboring ahupua 'a. 1 3 r This is readily noted by a examination of the archaeological and historical literature. Starting with Reinecke in 1930 and extending to the present , we see an increasing number of rreportscoveringthelowlandregions . The summarization and analysis of this data shows the use of these coastal , inshore and offshore areas as of economic importance in the prehistoric period . If the midlands were marginal , the coastal regions rwereofimport. This produced a drawl g attraction for people and cultural development within the coastal region , but not in the midlands . Here , only off and on incursions were made for rthegatheringofpiligrassforthethatchingofhomesand other structures, and the passage through these lands on travels elsewhere, hardly a reason for settlement, or even lingering rlongenoughtoleavetheirculturalmarksonthesurfaceofthe ground . Only in recent years do we see the accumulation of c cultural debris . Prior to the development of the village of Waii:oloa in the early 1970 ' s only the military left their mark on the study area . There is no question that some military personnel were in the region , perhaps during WW II , for we found the remains of field communication wire as well as a fair number of examples of schrapnel fragments . The latter showed clumping about centers of dispersal , just what would be expected if shells were fired into the area Finally , and with regard to methodology , we made use of r aerial photos and walked the length of the gullies to examine for the presence of cultural transformation , but to no avail .rNothingofaculturalnature , other than recent fence- lines , showed on the aerials . As my son was with me in the field and aided in the tran- sects , we were able to make eight passages each in a north- south , south-north direction. With these 1E north-south cross- ings combined with a larger number of east-west, west-east transects we were able to pass a given point on the landscape at no greater distance than approximately 60 to 90 feet. Even with this rather close proximity to previous passages we often rtimesdivertedifsomethingcaughtoureye . In all cases what caught our attention proved to be nothing more than at best, an outcropping of rock . r 4 r r REFERENCES CITED 1 Bonk, William J . 1985 "An Archaeological Survey in the Waimea-Pa auilo 1 Watershed Area of Portions of the Districts of South Kohala and Hamakua , County of Hawaii , Hawaii " With Addendum . ) Papers in Ethnic and Cultural Studies , 85-3 , University of Hawaii at Hilo .

The ratio is consistent with the ex istinq varied demographics and needs of the potential consumer market, mix of South Kohala employees. and to the maximum efficiency ofconstructionand land use It should be noted that survey results show a higher while incorporating traditional with innovative housing alternatives. percentage of management positions are in rentals rather than owned units. As such, it is reasonable to provide single family rental housing in addition to the single family sales. Many of these management positions involve transient personnel " climbing the corporate ladder" who are relatively mobile and not tied down with home ownership. 8) Lot Size - Lot sizes for the single family property should be varied with a minimum of approximately 4, 000 square feet ( in a formation similar to the Pines project in North Kona) to approximately 7, 500 square feet. A typical multiplex and shared housing is recommended to have a combined land area of 4, 000 to 10, 000 square feet. g) Buy- Back - To maintain the " affordability" of housinq developed on the County' s site, it is rea sonable to consider a " buy- back" condition similar to NFDC' s buy- back. A 10- year buy- back term appears reasonable to help eliminatespeculation, maintain an affordable housing stock and it does not unreasonably restrict the homeowner. 10) Financing Alternatives - Two alternatives to the buy- back' Include a ' sleeping second mortgage' or the shared equity' approach. These alternatives offer the opportunity to reduce selling prices cost recovej- y to the County. 11) Projected Market - The demographics of consumers for affordable housing market at Waikoloa include: development along r the North Kona/ South Kohala coast;Permanent work force at completed hotels; General population growth resulting from continued economic growth. 6 5 This report incorporates data from existing public documents POPULATION ESTIMATES - STATE AND COUNTY was well as studies, surveys and prospectus done by the private sector.

Population in modern history peaked at 73, 725 by Belt Collins ( and Peat Marwick Mitchell Progress during that year, largely as a result as the importation of Presentation for Kealakehe Planned Community labor for the sugar industry. The population decline between Development Housing Market Assessment) 1930 and the 19605 was primarily due to the increasing La' itani Housing Project Environmental Assessment mechanization of the sugar plantation, limited job Bank of Hawaii " Construction in Hawaii 1989" and a 1988 opportunities in other economic sectors, and the out migration report prepared by Donnelly Demographics of New York of residents.

Placing the improvements in the corner of the lot leaves more 1 3 than three quarters of the lot available for a variety of uses including retreat- tonal, open space. The compactness of the " house" and lot allows for a higher actual density while being perceived as having wide open spaces.The configuration of the " houses" should vary. Some would contain all two- bedroom units, others are a combination of two- and three- bedroom units, and some, three- bedrooms. This variability provides more desirability while giving an overall neighborhood appearance of diversity. The individual L- shaped configuration economizes space, particularly through the absence of interior hallways. Economy of construction has been considered in back- to- back placement of kitchens and bathrooms. The following illustrates some varieties of the zero lot line house.
