DocuSign Envelope ID: BE74E31 B-F73A-4A43--98D4E6CBC6F5 Watershed. Dublin Creek and Devany Canyon Creek do not have listed impairments, however, Dublin Creek and its tributaries have existing beneficial uses of warm freshwater habitat, wildlife habitat, water contact recreation, and water non -contact recreation. Temporary best management practices (BMPs), such as temporary erosion and sediment control, delineation of natural and/or sensitive areas, and site management, will be required to reduce sediment and pollutants to the creeks during construction. Site design measures include directing runoff from roofs and sidewalks to vegetated areas, minimizing land disturbance and impervious surface, maximizing permeability, using micro -detention areas, protecting sensitive areas, implementing self -treating areas, and implementing self -retaining areas. Source control measures would be provided for storm drains, landscaping, outdoor equipment/materials storage, fire sprinklers, and miscellaneous drain/wash water. Applicable low impact development (LID) measures for the Project to treat the new impervious surfaces include bioretention areas. The Project creates and/or replaces more than 1 acre of impervious surface and is within a white area with natural creeks designated by the Alameda County Clean Water Program's (ACCWP) as susceptible to hydromodification. Therefore, the Project is required to implement hydromodification management measures. The LID measures can also be used as hydromodification management measures and will adhere to the stormwater treatment and hydromodification management design criteria in the ACCWP's C.3 Stormwater Technical Guidance and applicable requirements from the City of Pleasanton. WRECO will perform a peer review of the documents for the Municipal Regional Permit (MRP) C.3 stormwater treatment best management practices (BMP) compliance and risk level assessment for compliance with the Construction General NPDES Permit. This includes review of BMPs sizing and any hydromodification analysis performed. Land Use FCS will evaluate the project for consistency with the City of Pleasanton General Plan, including Measures PP, QQ, and open space policies identified in the Land Use and Open Space Elements. FCS will also evaluate the proposed conversion of lands currently designated Public Health and Safety to confirm whether the proposed conversion would be consistent with the intent of relevant policies. Noise The proposed project contemplates construction and operational activities that could potentially expose surrounding land uses to excessive noise and vibration levels. Of particular concern are temporary increases in ambient noise levels during construction and permanent increases in ambient noise levels for operational activities (e.g., vehicle trips, truck deliveries, mobile and stationary equipment, etc.). FCS will prepare a Noise Analysis to evaluate the impacts of project -related construction and operational noise on surrounding land uses. The analysis will be wholly contained in the EIR and the supporting technical data will be appended. To perform this analysis, the following tasks are required. Background Information The general characteristics of sound and the categories of audible noise will be described. The regulatory framework related to noise, including applicable City and County plans, policies, and standards will be WRT" Ae4MCA I RMOt J "W-A I nir;rea rn I AMA FIRSTCAR80NSOLUTIONS.COM
