Traffic An Environmental Impact Report (EIR) dated August 2001 was prepared for the Downtown Specific Plan in which it was anticipated that the project site would be developed as a high- density residential use. Impacts and mitigations were addressed in this EIR. The use and proposed site layout are not anticipated to create any unique traffic or circulation circumstances. The applicants would be required to pay the City traffic fee and Tri- Valley Transportation fee as part of the project. Per the 2003 Annual Baseline Traffic Report, the a.m. and p.m. trip rates for multi-family residential units are .47 and .58, respectively. The a.m. and p.m. trip rates for single-family homes are .75 and 1.0 respectively. Thus, given the trip rates listed above, the proposed project would have a total of3.94 a.m. trips and a total of 5.16 p.m. trips. Residential projects with less than 10 trips in the a.m. and p.m. peak are considered small projects, not requiring a traffic study. There is an existing bus stop one block away from the project at the comer of Peters Avenue and St. Mary Street and numerous fixed route bus lines serve the Downtown area. Grading and Drainage The proposed project would result in an increase in paved surfaces on the site. Only minimal grading, for drainage purposes, is proposed. The rear yards of the single-family detached residences would be raised approximately .5 to I foot in elevation for drainage reasons. The applicants are proposing to grade the site such that storm water would filter into grass at the rear and front of the site. In the event of a large storm, excess storm water which does not filter into the grass would be collected in area drains which would take the water to the front yards in a bubble up system. Once the bubbler system is full, water would be piped to the gutter. Turf block is also proposed in the center of four driveways and for two of the uncovered parking spaces to help retain water on site. Staff believes that concrete pavers or turf block would be acceptable for the two uncovered parking spaces by unit B-2. Staff has added a condition of approval to address this. Power Lines There is an underground electrical line in Peters Avenue. The project will connect into this line. All power lines will be underground. Case No. PUD-37 Planning Commission Page-16-
