Communication No. 2019-09 (i) provides increased emergency evacuation opportunities. New development that is not well - connected with existing neighborhoods contri butes more cars and creates greater traffic congestion on collector roads. When new development is integrated into existing street patterns, providing additional choices for movement in and out of the neighborhood, new developments can actually increase co nnectivity within the region. Policy T RAN - 2. 1 : Connectivity Standards . Connectivity refers to the directness of links and the density of connections that make up the transportation network. Within the Kona Urban Area (UA) new development shall contribu te to this interconnected transportation network of streets, pedestrian, and bicycle access that work to disperse traffic and connect and integrate new development with the existing fabric of the community. Proposals for new development or redevelopment w shall should meet the following connectivity standards: 1. Maximum Block Size. In lieu of Hawai i County Code (HCC) Section 23 - 29(c), the maximum length of blocks for predominantly residential subdivisions shall be 800 feet, unless unfeasibl e due to natural topography, protected resources, or surrounding development patterns. 2. Connection to Adjoining Development. The road system for new development shall contribute to the local transportation network. To supplement HCC Section 23 - 40, at a m inimum, new subdivisions shall incorporate and continue all collector streets, and selected local streets to adjoining property. If a portion of the stub - out is not improved, the current developer shall improve the stub - out portion , where practicable . Co nnection to adjoining properties may not be required if seriously constrained by topography or other physical hindrances, or in cases where through travel cannot occur because the property is bounded by development with private streets previously allowed. 3. Gated Entry. In the Kona UA outside of General Plan Resort or Resort Node , gates will be prohibited across new roadways identified to service connect to the local transportation network , as identified in Figure 4 - 2a . 4. Cul - de - sacs Discouraged. Cul - de - s acs are discouraged based on Policy T RAN - 2. 1 (1) Maximum Block Size and Policy T RAN - 2. 1 (2) Connection to Adjoining Property unless construction of a through street is found to be impracticable. Where cul - de - sacs or dead - end streets are allowed, they shal l meet the prevailing standards in the Chapter 23 Subdivision Code. 5. Future Extensions. Roads serving future transportation interconnectivity will be identified for any proposed subdivision located adjacent to a vacant parcel. Alignment and placement of f uture extensions and stub - outs shall take into account realignments to proposed transit routes as a result of resource preservation or other unforeseen obstacles to original road alignments. In the case that impact studies performed for adjacent parcels r esult in realignment to the proposed transit routes (Figures 4 - 2a to 4 - 2d), future extensions and stub - outs between subdivisions and or parcels shall be collaboratively agreed upon by the developers and appropriate governmental agencies. To supplement HCC Section 23 - 44, where necessary to give access to or permit a satisfactory future subdivision of adjoining land, or to conform with the Official Transportation Network Map (Figures 4 - 2a to 4 - 2d), a street stub - out or pedestrian path improved to the boundary is required unless financially guaranteed to enable the County to coordinate the stub - out construction as a regional project or in coordination with the development of the adjoining property. Applicants submitting preliminary development plans shall prov ide for feasible extension of 8
