Storm Water Review & Approval for Development / Construction Projects

The Public Services and Engineering Department is responsible for implementing the State of California storm water pollution prevention mandates per National Pollutant Discharge Elimination System (NPDES) Order Number R9-2013-0001 (Order) and subsequent amendments. The City's enforcement authority is found in Coronado Municipal Code Title 61: Storm Water and Urban Runoff Management and Discharge Control.

The Order requires the development and construction community to comply with minimum land development standards for the permanent treatment of storm water runoff that are verified and approved during the planning review and approval phase. In addition, the construction phase requires the implementation of Best Management Practices (BMPs) to minimize erosion, sediment, and storm water runoff pollutants. 

The Public Services and Engineering Department reviews and approves storm water requirements relevant to land development and construction projects. Applicants are encouraged to contact City staff early in the project planning process and prior to permit application submittal to streamline and expedite the project review and approval process. All land development and construction projects shall meet the minimum storm water requirements prior to receiving building permits. 

Storm water staff counter support at City Hall is offered Monday and Wednesday from 10 am to 2 pm, and by appointment at 619-522-2653 or email the Storm Water Review team at [email protected].

Each project phase, as noted below, shall meet the minimum requirements based on the project’s risk assessment assigned by the City. Project categories are determined by completing the Storm Water Assessment Forms I-1 and I-2, and submitting to Community Development (Building Department). Incomplete or inaccurate entries may result in permit approval delays.

Project phases and key steps: 

Development Planning and Design Phase 

The land development project design team disciplines (planner, architect, civil engineer, landscape architect, etc.) involved in the planning and design should coordinate to incorporate site design features and treatment controls for storm water runoff to meet the City's requirements. It is highly recommended that the design team and owner meet with the City's Storm Water Program staff to review the storm water design features to help expedites the formal review and approval of the project's building permits. Pre-submittal appointments can be arranged by email at [email protected]

Construction Phase 

The following activities are included under the construction phase: 

  • Demolition (partial or full) 
  • Land clearing, grubbing, and grading
  • Excavation, including excavation for below grade construction with or without shoring
  • Groundwater dewatering
  • Construction of all structures, impervious area (e.g., driveways, parking), and landscaping.

The construction phase includes partial or full demolition of existing structures and impervious areas, and any land disturbance or grading activities. A demolition permit shall be obtained from the City and shall include a storm water best management practices (BMPs) exhibit to mitigate debris, trash, erosion, and sediment from demolition, clearing, and grading activities. All phases of construction are subject to City inspection to assess compliance with permit approvals and regulatory requirements. 

Other permits may apply to a project site, and each phase of construction must include specific BMPs to manage pollutants and sediment generated from the activity. The City may require construction BMP maps or exhibits for each phase of construction. 

When the construction phase of the project is complete, to obtain final approval, please contact the storm water construction inspection group at (619) 522-6304 or by email at [email protected] at least two days in advance. The following checklist is available to verify that all minimum requirements are complete prior to scheduling the final inspection.
