PUD-6~ Environmental Checklist <br />e) Create or contribute runoff water which would ~ ~ ^X <br />exceed the capacity of existing or planned <br />stormwater drainage systems or provide <br />substantial additional sources of polluted runoff? <br />f) Otherwise substantially degrade water quality? ~ ~ Y <br />g) Place housing within a 100-year flood hazard ~ ~ ~ ~X <br />area as mapped on a federal Flood Hazard <br />Boundary or Flood Insurance Rate Map or other <br />flood hazard delineation map? <br />h) Place within a 100-year flood hazard area ~ ~ ~ ^X <br />structures that would impede or redirect flood <br />flows? <br />i) Expose people or structures to a significant risk of <br />loss, injury or death involving flooding, <br />including flooding as a result of the failure of a <br />levee or dam? <br />j) Inundation by seiche, tsunami, or mudflow? <br />Discussion <br />a,e,f) The project will be required through the building permit and construction process to <br />incorporate best management practices (BMP's) for discharges resulting from this <br />development. The City has adopted the most recent Regional Water Quality Control <br />Board stormwater discharge requirements related to design, construction, and <br />implementation of the subject site. A design feature incorporating the BMP's is the <br />provision of bio-swales used as on-site treatment prior to discharge into the storm water <br />system. Therefore, this would be a less-than-significant-impact. <br />b) The project will not use a well to pump ground water for this project. Any existing wells <br />will be required to be abandoned pursuant to the Alameda County Department of <br />Environmental Health. The development of this project does not anticipate a loss of <br />groundwater recharge potential. Therefore, this would be categorized as no-impact. <br />c,d) Site development will slightly alter the existing drainage pattern from its existing <br />condition. The improvements will not alter the alignment or stability of the existing <br />creek. Therefore, this would be categorized as rao-impact. <br />g-i) Housing will not be placed within a 100-year flood hazard. The development will not <br />expose people or structures to a significant risk of loss, injury or death involving <br />flooding. Therefore, this would be categorized as no-impact. <br />21 <br />
