Memorandum Date: March 20, 2017 To: Mr. Jonathan Hayes, Greystar From: Kai-Ling Kuo, Michelle Hunt Subject: Mixed-Use Development and Transit Trip Reduction Evaluation for the 1409 El Camino Real Traffic Study The memorandum summarizes the evaluation of the mixed-use development and transit trip reduction percentages assumed in the 1409 El Camino Real Traffic Study, which were based on the reductions used in the transportation and circulation chapter of the Redwood City Downtown Precise Plan (DPP) EIR adopted in 2011. The DPP EIR used the Environmental Protection Agency (EPA) mixed-use development (MXD) model to derive a 21 percent daily trip reduction with 12.3 percent and 19.1 percent reductions in the AM and PM peak hours, respectively. The model results were based on the adopted DPP land uses, projected employment within one mile of the DPP area, average household size, and vehicles owned per household. The MXD model was used to estimate the internal trip capture associated with mixed-use development and the bicycle and walking trips. In addition, a 5.6 percent daily transit trip reduction with 7.3 percent and 6.0 percent in the AM and PM peak hours, respectively, was applied in the DPP EIR based on the information produced by MTC. To evaluate whether the reduction percentages used in the DPP EIR are appropriate for the 1409 El Camino Real traffic study, the MXD model was used to re-estimate the trip reduction based on the most recent US Census American Community Survey (ACS) data and the Association of Bay Area Governments (ABAG) land use projections. The mode choice information produced by Metropolitan Transportation Commission (MTC) was used to evaluate the transit trip reduction. Mixed-Use Development Trip Reduction The MXD model is designed to estimate trip reduction from the ITE trip generation rates to account for the effect of mixed-use development. The input variables used in the calculations include: development area, number of intersections in the area, employment within one mile of the area, average number of vehicles owned per household in the area, average household size in the area, and proposed land uses in the area. Because the project is located within the DPP area and will contribute to and benefit from the proposed mixed-use setting in the DPP area, the trip reductions for the 1409 El Camino Real project were estimated using the projected DPP land uses to reflect the trip reduction under DPP buildout conditions. Table 1 summarizes the inputs used for the calculations and the resulting MXD trip reductions. Based on current ACS data and ABAG land use projections, the mixed-use development in the DPP is expected to result in a 22.2 percent daily trip reduction, with 16.2 percent and 21.9 percent reductions in the AM and PM peak hours, respectively. The results show that the MXD trip reduction estimates prepared using the updated ACS data and ABAG projections are greater than the trip reductions assumed in the DPP EIR and the 1409 El Camino Real Traffic Study. Therefore, the mixed-use trip reductions applied in the 1409 El Camino Real Traffic Study are considered to be conservative (low) based on the trip reductions estimated using current data. 8.A. - Page 125
