4.8 Hydrology and Water Quality Context: The Project could would after existing drainage patterns andpotentially increase the amount of impervious surfaces in the plan area. Thus it could potentially increase stone water runoff volumes and affect surface water quality without appropriate mitigation. Storm water pollution from surfaice- bome contaminants such as oils, fuels, dust, can degrade water quality m the San Francisco Bay. Also, temporary water quality degradation could be an issue during construction of the project. Given the low elevation and relief of the plan area, there is a possibility of flooding during 100 -and 5X0 -year stone events. 4.9 Land Use and Planning Context: The Project will introduce new and different land uses to the plan area. 4.10 Noise Context: Construction and operation of the Project would temporarily affect short- term ambient noise levels in the Vicinity of construction sites, as well as long-term noise levels. The Project area includes existing noise generating uses, including nearby highways, active railroad tracks, and the San Carlos Airport. • 11111 prulecr-revei mmgauun measures to aauress nazares ane hazardous materials, specifically from project and site-specific Assumption: requirements or recommendations in a Protect -specific Phase Minimal change is 1 report prepared by a qualified consultant of the project anticipated to the Setting sponsor.
