D D D [Xl Discussion a,e,t) The landscape areas adjoining the project's intema1100p street will be designed and graded to function as a bio-retention swa1e. The individual lots will be graded to drain towards the reten- tion swales and then to catch basins within the swales before entering the City's storm drain sys- tem. The project will be required through the building permit and construction process to incor- porate best management practices for discharges resulting from this development. The City has adopted the most recent Regional Water Quality Control Board stormwater discharge require- ments related to design, construction and implementation of the subject site. Therefore, this would be a less-than-signijicant-impact. b) The project will not use ground water for this project. Any existing wells will be required to be abandoned pursuant to the Alameda County Department of Environmental Health. The devel- opment of this project does not anticipate a loss of groundwater recharge potential. Therefore, this would be categorized as no-impact. c-d) Site development will alter the existing drainage pattem from its existing condition. The im- provements will not alter the alignment or stability of any Arroyo within Pleasanton's jurisdic- tion. Therefore, this would be categorized as a less-than-signijicant-impact. g-i) Housing will not be placed within a 100-year flood hazard. The development will not expose people or structures to a significant risk of loss, injury or death involving flooding. Therefore, this would be categorized as no-impact. j) The City of Pleasanton is not at risk from seiche, tsunami, or mudflow. Therefore, this would be categorized as no-impact. 9.
