Stormwater Technical Resources

The following documents are provided to aid the development community in preparing stormwater designs:

• Declaration of Covenant and Grant of Easement for Inspection and Maintenance of Stormwater Facilities and BMPs (PDF)
  All development projects which construct stormwater facilities are required to record a Declaration of Covenant which obligates the property owner(s) to maintain their stormwater facilities. Use this template for projects which do not qualify as Small Projects.
  
  
• Small Project Site Plan/Report Template (PDF)
  Preparation of Stormwater Site Plan, also called a drainage report, can be a daunting task and usually requires the services of a professional to prepare. This template may be used to address the Stormwater Site Plan requirements for small projects which do not require a full stormwater design. The template may be filled out by the property owner or project proponent, although some elements may still require professional qualifications to prepare. When fully completed this template addresses all of the requirements of Minimum Requirement 1 in the Stormwater Management Manual for a Stormwater Site Plan, and may be submitted as the Stormwater Site Plan for the proposed project.
  
  
• Small Project Declaration of Covenant for Inspection and Maintenance of Onsite Stormwater BMPs (PDF)
  Projects that must address only Minimum Requirements 1-5 in the Stormwater Management Manual, and are eligible to submit the Small Project Site Plan Template, should use this Declaration of Covenant template instead of the standard facility version above.

Infiltration Infeasibility Map

The Infiltration Infeasibility Map identifies areas within the City where infiltration best management practices (BMPs) can be deemed infeasible for the purposes of complying with stormwater regulations. This information is also available on the Map Everett Interactive Map.

Interactive Utility Mapping

The Map Everett Interactive Map includes mapping of the City's storm drainage system. This map can be used to identify downstream flow routes from a site and identify existing stormwater infrastructure.

Construction Stormwater General Permit

Projects which disturb one or more acres of land and discharge to surface waters must obtain coverage under the Ecology's Construction Stormwater General Permit.

Industrial Stormwater General Permit

Some industrial operations must obtain coverage under the Industrial Stormwater General Permit, which regulates stormwater discharges from certain types of industrial sites.

Sand and Gravel Stormwater General Permit 

Businesses involved in the production, hauling, or storage of sand or gravel materials may require coverage under the Sand and Gravel General Permit.

Boatyard General Permit

Facilities which store, maintain, or transport water craft may require coverage under the Boatyard Stormwater General Permit.

Underground Injection Wells

Stormwater facilities which infiltrate stormwater by means of an underground facility such as an infiltration trench or vault may need to be registered as an underground injection well (UIC). Surface facilities, such as ponds or rain gardens generally do not require registration.
