Stormwater Requirements Applicability Checklist

Use the Stormwater Requirements Applicability Checklist to determine your project's permanent and construction stormwater best management practices requirements. 

Questions regarding this checklist may be directed to Melissa Dailey, Environmental Protection, at 619.686.8088.


Permits and Guidance Documents

Regional Water Quality Control Board Order No. R9-2013-0001, National Pollutant Discharge Elimination System (NPDES) Permit No. CAS0109266, (Municipal Permit)

This permit was adopted in May of 2013 and replaces the previous permit Order No. R9-2007-0001.

Construction Phase Stormwater Document Templates

The Port requires projects that involve construction activity on Port tidelands to prepare and submit a document that identifies the project's construction-related activities that may affect stormwater quality and describes how pollution prevention measures will be utilized accordingly. The Port also requires minimum best management practices (BMPs) for all construction projects on Port tidelands. These minimum BMPs are listed in the Port Jurisdictional Runoff Management Plan (JRMP) document, Chapter 5. For projects that will disturb less than one acre area of soil, a Construction Best Management Practice (BMP) Plan is required. For projects that disturb greater than one acre area of soil, a Construction Stormwater Pollution Prevention Plan (SWPPP) is required. The use of the Port's Construction BMP Plan and SWPPP templates are required.

For projects less than one acre:

For projects greater than one acre:

Stormwater Quality Management Plan (SWQMP) Templates for Standard (Minor) Development and Priority Development Projects (PDPs)

Pursuant to Regional Order No. R9-2013-0001 as amended by Nos. R9-2015-0001 and R9-2015-0100, the Port Standard Urban Stormwater Mitigation Plan (SUSMP) is to be replaced with a Best Management Practice (BMP) Design Manual that provides updated procedures for planning, selecting, and designing permanent structural stormwater BMPs based on specific performance standards. In place of a project USMP submittal, all new development and redevelopment projects are required to complete and submit to the District a Stormwater Quality Management Plan (SWQMP) accurately describing how the project will meet applicable stormwater requirements. Projects categorized as Priority Development Projects (PDPs) must incorporate structural treatment controls into the site design and, where applicable, address potential hydromodification impacts from changes in flow and sediment supply. Refer to the Port's Stormwater Requirements Applicability Checklist (included in the Tenant Project Application) to determine if your project is a Standard Project or a PDP.

Following the adoption of Order No. R9-2015-0100 on November 18, 2015, the Port is to begin implementing the BMP Design Manual February 16, 2016. To qualify as a “grandfathered” project under Order No. R9-2013-0001, a project must both obtain project approval prior to the close of business on February 16, 2016 and commence grading activities within 180 days of February 16, 2016.

Please note: Environmental Protection requires a two week window for stormwater submittal review. Any project that intends to qualify as a “grandfathered” project must submit the necessary stormwater document(s) in their entirety by no later than close of business February 2, 2016.

Port Best Management Practice (BMP) Design Manual

 

As directed under the new MS4 permit (Order No. R9-2015-0100), the Port SUSMP is to be replaced with a BMP Design Manual. The Port BMP Design Manual provides updated procedures for planning, selecting, and designing permanent structural stormwater BMPs based on specific performance standards outlined in the permit. The Port’s BMP Design Manual is consistent with the Model BMP Design Manual developed collectively by the San Diego County copermittees.

Project Priority Level for Storm Water Pollution Prevention Plans (SWPPPs)

The San Diego Regional Municipal Permit (Permit) (Order No. R9-2007-0001) requires that construction sites are assessed on their potential threat to water quality.  Every construction project on Port tidelands must be assessed and prioritized based on the project’s threat level during the project approval process.

The Port has developed guidelines for prioritizing Port construction sites.  The highest priority category under which a project falls will be the priority classification. Each construction project will be categorized into low, medium, high, and exceptional priority levels.

Use the following tables to determine the project’s priority level.  First, determine how many wet seasons will the project activities will occur during (none, one, or more).  Once this has been determined, then use the appropriate table to find the project’s priority level.

For projects where construction activities will occur during no wet season or one wet season:

 

 

Project Size

Less than 1 acre

1-5 acres

5-50 acres

Greater than 50 acres

Not in or over a receiving water

Low Priority

Medium Priority

High Priority

Exceptional Priority

In or over a receiving water

High Priority

High Priority

High Priority

Exceptional Priority

For projects where construction activities will occur during more than one wet season:

 

 

Project Size

Less than 1 acre

1-5 acres

5-50 acres

Greater than 50 acres

Not in or over a receiving water

Medium Priority

High Priority

High Priority

Exceptional Priority

In or over a receiving water

High Priority

High Priority

High Priority

Exceptional Priority

The priority level must be noted in the project SWPPP and on the SWPPP inspection checklist.  The outcome of this assessment dictates construction inspection frequencies, temporary BMP requirements, and the need for advanced treatment systems discussed in The Port’s JURMP. It should be noted, that the Port may reconsider and reassign a higher priority level of a construction site if a violation occurs during the course of the project or if the factors of the project change.
