Hydrology and Water Quality. The Project will have less than significant impact with mitigation on Hydrology and Water Quality. The land at or near the proposed MPDCP site have been previously graded and leveled for agricultural use, and no major grading or earth-moving activities would occur. Before and during construction, the project would disturb more than one acre, the awardee will be required to obtain a General Construction Activity Storm Water Permit from the State Water Resources Control Board (SWRCB) for storm water discharges associated with construction activities. Applicant is required to execute a stormwater pollution prevention plan (SWPPP). Implementation of the Mitigation Measure HYD-1 of the MMRP would reduce impacts of Water Quality to less than significant. The project site is located within a Flood Zone, following construction of the biogas upgrading facility but prior to plant operations, applicant will implement Mitigation Measure HYD-2, to reduce potential impacts of Hydrology to less than significant.
Hydrology and Water Quality. In addition, before and during construction, the project may disturb more than one acre at or near the MPDCP site, which would impact Hydrology and Water Quality. Mitigation measures for Hydrology and Water Quality, the Applicant shall implement the SWPPP and complete flood proofing will reduce impacts to hydrology.
Hydrology and Water Quality. Issues The Project site lies within the Xxxxxx Creek watershed on the eastern side of Marin County between the Novato and Gallinas watersheds. The Xxxxxx Creek watershed covers 12 square miles with 30 miles of channels. Xxxxxx Creek flows eastward from open space and private ranches on Big Rock Ridge through multiple unincorporated housing developments running just south of the Project site before goes under Highway 101 and enters the baylands at the Northwest Pacific Railroad Bridge. According to a preliminary review of site hazards, the Project site is located near a high flood hazard area but appears to be outside the limits of the 100 year flood zone. The analysis in the Housing Element DSEIR determined that the site was not within a flood hazard area as mapped by FEMA. In addition, the proposed Project may affect stormwater flows and water quality of offsite discharges through changes to existing drainage patterns. The Project may have to comply with the C.3 regulations of the NPDES (National Pollution Discharge Elimination System) based on the proposed size of Marinwood Plaza Project EIR 1-27

Hydrology and Water Quality. As stated above, the Project site is mostly covered in impervious surfaces with paved surface parking lots and buildings. Therefore, the demolition of the existing buildings and the construction of new buildings would likely result in minimal changes to impervious surfaces and would have less-than-significant impacts on stormwater runoff quality or quantity, flooding, or drainage. The analysis will consider how the change in building footprints and impervious surfaces compare to existing conditions would potentially affect peak flow rates. It is expected that the same hydrology impacts as analyzed in the ConnectMenlo EIR would occur. To analyze impacts specific to the Project site, ICF will review technical information received from the Project Sponsor, such as hydrology or drainage reports.
Hydrology and Water Quality. The February 2007 IS/MND requires the project to implement Mitigation Measures HYDRO-1 through HYDRO-5, which requires the preparation of a Storm Water Pollution Prevention Plan prior to site grading activities in order to protect surface water quality in the project area. The Storm Water Prevention Plan shall comply with the most current standards established by the Regional Water Quality Control Board. Additionally, a Water Quality Management Plan and detailed hydrology analysis must be prepared subject to the standards of the City of Perris and the Riverside County Flood control and Water Conservation District. Implementation of these Mitigation Measures would reduce potential impacts on hydrology and water quality to a less than significant level. Noise The February 2007 IS/MND requires the project to implement Mitigation Measures NO-1 though NO-10, which includes the building of block walls and noise barriers, as well as the enclosed dumping of solids waste and maintenance of onsite equipment. Onsite equipment, transfer trucks, and construction equipment should also be provided with approved muffler systems. Outdoor rock crushing and construction activities are limited to specific times as permitted under the City of Perris Noise Ordinance. Implementation of these Mitigation Measures would reduce potential impacts on noise to a less than significant level Public Services The February 2007 IS/MND requires the project to implement Mitigation Measures PUB-1 though PUB-8, which includes review of onsite fire protection systems by the Riverside County Fire Department, updating the facility’s Fire Control Plan, connection to a domestic water system, installation of security detection systems and fire hydrants, and preparing a wall and fencing plan and lighting plan. Implementation of these Mitigation Measures would reduce potential impacts on public services to a less than significant level Traffic and Circulation The February 2007 IS/MND requires the project to implement Mitigation Measures CIRC-1 through CIRC-5 which require the construction of a dedicated primary arterial road, including off street parking, onsite traffic striping, and offsite traffic signals. Implementation of these Mitigation Measures would reduce potential impacts on traffic and circulation to a less than significant level.
