The Committee presented concerns regarding traffic issues and requested that these items be addressed with the developer. As a response,the developer provided an amendment to the Traffic Impact Analysis Report;the summary of the data is included as"Exhibit A". The Department of Public Works(DPW) is actively working with the developer to address the traffic issues presented through Planning Committee. DPW has provided a letter to the developer to address the needs for mitigation measures, attached as "Exhibit B". Should you have any questions, contact Cristina Pineda at(808)323-4304.

This addendum projects the additional traffic that is anticipated with the opening of this school. Key points are: • There are no changes in the Level of Service (LOS) of any of the intersections when adding traffic from the proposed Honua'Ula Housing project. • The LOS calculations indicate an increase in delays at the study intersections, but no additional deficiencies. • The ITE Trip Generation Manual, loth Edition was referenced to determine the estimated AM and PM peak hour trips. • Travel patterns were based on the existing patterns measured in our previous traffic counts. • Adding the estimated school traffic changes the LOS at two conditions: Uluaoa Street & Palani Road, AM East Bound, changes from a LOS of C to a LOS of D. Still within County standards. Kealaka'a Street & Palani Road, Overall LOS, changes from LOS B to LOS C. Still within County standards. Date: September3. 2O21 Sub'ect: Honua'U|mTK\Addenda INTENT The intent of this memo serves to provide an updated evaluation for the Honua'Ula TIA to account for additional background traffic occurring at the nearby Makua Lani Christian Academy School. The school ielocated atthe terminus ofKea|ahaoStreet,justnorthwest ofthe subject property. Field counts were taken in early August 2021 while this school was not in session. Therefore, traffic volumes have been adjusted to account for the additional estimated vehicular activity during the study periods, TRIP GENERATION Mohua Lani Christian Academy serves grades 5-12 with u student enrollment ofapproximately 190-etudento. To account for estimated trips aawocjmbad with AM and PM peak school activity, |l[E Trip Generation Manual, 1Oth Edition was referenced. In review ofthe manual, the most comparable Land Use Code (LUC)was debanninmj to be LL8C 536—Private School. Estimated AM and PM peak hour trips are summarized in the table below based on student population. Table 1: School Trip Generation Ips In in Private School 190 94 60 154 46 64 110 The nearby school is estimated to increase background volumes by an additional 154 vehicles in the AM peak hour and 110 additional vehicles in the PM peak hour. Figures 1 &2 on the following page illustrate the estimated AM and PM peak hour trip distribution at the study intersections. Percentages are primarily based on existing travel patterns and proximity to nearby residential ` areas. INTERSECTION VOLUME ADJUSTMENTS All counts used in the original analysis have been adjusted to account for the additional school- related traffic shown in the preceding figures. Figures 3 &4 identify existing baseline peak hour counts. Figures 5&6 illustrate forecast 2026 peak hour volumes without the proposed Honua'Ula housing development. Figures 7 &8 illustrate forecast 2026 peak hour volumes with the proposed development. LEVEL OF SERVICE Existing Level of Service (LOS) The table below was taken from the Honua'Ula TIA which documented existing LOS at the study intersections. Presented in Table 3 are the adjusted LOS calculations after adding in the additional school-related traffic volumes.

However,no additional deficiency was noted other than the known deficiency at Uluaoa Street&Palani Road.The AM peak hour is estimated to operate at LOS E with or without the proposed housing development. The PM peak hour is estimated to operate at LOS F with or without the project. No new recommendations or mitigations apart from the original are identified with the adjusted analysis.The presence of the school activity at the deficient intersection is shown to cause high delays for motorists intending on departing from Uluaoa Street onto Palani Road.The signal to the south at Kealaka'a Street is shown to have sufficient capacity to accommodate a potential reroute in traffic patterns.
