Initial Study and Negative Declaration DISCUSSION a -f. No streams, rivers, drainage channels, etc. run through the site and, therefore, the project would not alter the course of any body of water. The northern portion of the site is sloped, and the proposed preliminary drainage plan for the project indicates that the existing CalTrans stormwater drainage system would be relocated within the project site to continue to handle the runoff from the freeway. The proposed preliminary drainage plan also includes a drainage system that would handle the on -site runoff for the proposed development. As a portion of the site is undeveloped, the proposed development would increase impervious area by approximately 90 %. As proposed, site drainage will be directed towards bio- retention planters located in various areas of the site before draining into the City's storm drain system. The project would be required to incorporate best management practices (BMP's) during construction to minimize erosion and stormwater pollution. The project would be required to comply with all applicable stormwater runoff requirements. The project would not use a well to pump ground water. The coverage of impervious surfaces on the site would change with implementation of the project. However, groundwater recharge would not be substantially affected because the site would include stormwater management features that would allow stormwater to percolate into the aquifer. Therefore, these would be Tess- than- significant impacts or no- impact. g-j The project site is not located within the 100 -year flood zone6 and the proposed project does not include any housing units. The project would not impede or redirect flood flows or expose people or structures to a significant risk of flooding. The project site is not in a location where the project would be subject to a seiche, tsunami, or mudflow. Therefore, these would be no- impact. 5.10. LAND USE PLANNING ENVIRONMENTAL SETTING The project site comprises vacant land, a parking lot, and a portion of a shopping center. It is bordered on the west by Pleasanton Square II Shopping Center and commercial uses west of Johnson Court; on the north by the 1 -580 EB Hopyard Road Off -Ramp; on the east by Hopyard Road and commercial uses on the east side of Hopyard Road; and on the south by Owens Drive. STANDARDS OF SIGNIFICANCE For purposes of this environmental document, an impact is considered significant if the proposed project would: 33
