Stormwater Management Action Planning

Current Phase:

The City will develop a Stormwater Management Action Plan (SMAP) for the Schell Creek planning unit no later than March 31, 2023.

The final Receiving Water Assessment and Prioritization can be found here: Receiving Water Assessment and Prioritization

The comment period for the Receiving Water Assessment and Prioritization process was April 28 to May 28, 2022.

Receiving Water Conditions Assessment

S5.C.1.d.i Phase II Permit requirement: 

Permittees shall document and assess existing information related to their local receiving waters and contributing area conditions to identify which receiving waters are most likely to benefit from stormwater management planning.

By March 31, 2022, Permittees shall submit a watershed inventory and include a brief description of the relative conditions of the receiving waters and the contributing areas. The watershed inventory shall be submitted as a table with each receiving water name, its total watershed area, the percent of the total watershed area that is in the Permittee’s jurisdiction, and the findings of the stormwater management influence assessment for each basin. Indicate which receiving waters will be included in the S5.C.1.d.ii prioritization process. Attach a map of the delineated basins with references to the watershed inventory table. 

Receiving Water Prioritization

Phase II S5.C.1.d.iii Permit requirement: 

No later than June 30, 2022, staff shall document a prioritized and ranked list of receiving waters. Staff shall document the priority ranking process used to identify high priority receiving waters and shall identify at least one high priority catchment area of focus for the Stormwater Management Action Plan (SMAP).

Stormwater Management Action Plan

Phase II S5.C.1.d.iii Permit requirement: 

No later than March 31, 2023, Permittees shall develop a SMAP for at least one high priority catchment area from (ii) above that identifies all of the following:

(a) A description of the stormwater facility retrofits needed for the area, including the BMP types and preferred locations.

(b) Land management/development strategies identified for water quality management.

(c) Targeted, enhanced, or customized implementation of stormwater management actions related to permit sections within S5, including:

  • IDDE field screening,
  • Prioritization of Source Control inspections,
  • O&M inspections or enhanced maintenance, or
  • Public Education and Outreach behavior change programs

Identified actions shall support other specifically identified stormwater management strategies and actions for the basin overall, or for the catchment area in particular.

(d)Identification of needed changes to local long-range plans to address SMAP priorities, if applicable.

(e) A proposed implementation schedule and budget sources for:

  • Short-term actions (i.e., actions to be accomplished within six years), and
  • Long-term actions (i.e., actions to be accomplished within seven to 20 years).

(f) A process and schedule to provide future assessment and feedback to improve the planning process and implementation of procedures or projects.

 

Stormwater Comprehensive Plan Update

This project will include a review of previous plans and studies, current information, and regulatory requirements to develop a stormwater comprehensive plan to address: regulatory compliance; watershed and basin delineation; stormwater system modeling/analysis; maintenance and replacement of existing stormwater infrastructure; potential water quality and flood control projects; and a gap analysis to identify resources required to meet current and future needs.

The comprehensive plan will inform the Capital Improvement Program by identifying surface and stormwater projects to meet operational and regulatory requirements.

The Stormwater Comprehensive Plan will be informed by the City of Ferndale Comprehensive Plan which can be found here.

Current Phase

Northwest Hydraulic Consultants has been selected to update the Stormwater Comprehensive Plan and develop a Stormwater Management Action Plan. Work will begin in 2021 and is anticipated to finish in late 2022.
