City of Santa Ana Proposal for the Bender Ready -Mix Concrete Manufacturing Project W; Initial Study and Mitigated Negative Declaration 3.3 DRAINAGE AND WATER QUALITY RBF's Stormwater Management Department will prepare the water quality impact review for the EIR. Based on the project description provided by the City of Santa Ana in the RFP, the project does not involve any grading or construction._ so no impacts to hydrology, floodplain, and/or groundwater would result from a CEQA perspective. Additionally, there are no requirements for stormwater quality BMPs unless there is "redevelopment" of the property. However, RBF has noted that the facility is located in the Santa Ana -Delhi Channel Watershed, which is tributary to Newport Bay. Newport Bay has several Total Maximum Daily Loads (TMDLs) that may require structural BMPs, therefore, this scope of work focuses on the water quality impacts associated with the proposed land use. Field Investigation/Data Collection. RBF will conduct a site visit to verify onsite land uses and existing structural BMPs. The review will include investigation of the general operations and drainage facilities. RBF will research available water quality data. This task includes one kick-off meeting with City drainage and water quality staff. The results of the investigation shall identify any additional data requirements to be provided by the City. Water Quality Review. RBF will prepare a preliminary assessment of the stormwater quality impacts from the proposed land use. The assessment will discuss the TMDLs for the Newport Bay and whether or not BMPs will be required. The decision to required BMPs will be made jointly between the City of Santa Ana water quality staff and RBF. Should the review identify that BMPs are required, a list of a acceptable facilities will be identified which can provide mitigation of water quality concerns as part of a conceptual water quality program for the land use and a adopted solution can be selected from the recommended list. Technical Memorandum. RBF will prepare a written memorandum summarizing the "no impact" finding for the hydrology, floodplain, and groundwater impacts. 4.0 CEQA INITIAL STUDYIASSESSMENT RBF will prepare an Initial Study in accordance with the CEQA Guidelines. The Initial Study will include detailed explanations of all checklist determinations and discussions of potential environmental impacts. The analysis shall be in accordance with Sections 15063, 15162, 15167 and 15168 of the CEQA statutes. The Initial Study report will be presented as follows: 4.1 INTRODUCTION This section will cite the environmental review requirements of the Project, pursuant to the CEQA Guidelines. The Introduction will include the Project location, environmental setting, existing uses on -site and in the vicinity, the Project description (confirmed by the City in Task 1.0), Project phasing, relevant background/history information, and zoning considerations. 4.2 ENVIRONMENTAL CHECKLIST This section will include a summary page of Project information followed by an explanation of factors considered for potential impacts. The Initial Study Checklist will be presented in a four column JN 00-000300.10P • 4 • August 27, 2009
