Long-Term Stormwater Management Plan

(Long-Term Stormwater Maintenance Agreement)

A LTSMP (Long-Term Stormwater Management Plan) is a post-construction agreement that is designed to provide long-term, effective stormwater management. It ensures that stormwater infrastructure is maintained and operated in accordance with regulatory requirements and best management practices. It also provides ongoing monitoring and inspection of stormwater systems to ensure proper functioning.

What is a LTSMP

Completing and submitting a Utah Long-Term Stormwater Management Plan (LTSWMP) is being enforced more and more by the EPA, Utah State, and local Utah cities.

The LTSWMP is a plan that details long-term stormwater controls and what inspections and maintenance are required after construction is complete and must be recorded at the County and maintained by the property owner.


It is required for all HOAs, commercial buildings, multi-family projects, and private units constructed after 2011 that include stormwater drains or mitigations on-site that haven't been turned over to the municipality.


Among a variety of items, these might include the inspection and maintenance of:

  • parking lot drainage,

  • on-site storm drains

  • dumpster and trash areas 

  • landscaping

  • permeable pavers

  • underground low-impact development (LID) devices

The LTSWMP is recorded with the County and will be the responsibility of the property owner for the life of the property, even when it was provided by the initial developer or builder.

If the City or State is requiring a LTSWMP, Accena SWPPP Services can make this a quick, easy, and painless process.
