Long-Term Stormwater Management Plan Documents
The Clean Water Act resulted in the inaction of laws and local regulations that require property owners to be environmentally responsible, whether the property is owned by the government or private owners. Riverton City’s Municipal Separate Storm Sewer System (MS4) Permit, identifies specific regulations requiring regulatory mechanisms that protect our water resources from the impacts of development.
A City ordinance (13.20) was passed, to satisfy the MS4 regulation, requiring new development to create a Long-Term Stormwater Management Plan and enter into an Agreement (LTSWMP). To comply with this ordinance, Riverton City has also created an LTSWMP for the new public works facility located at 12526 South 4150 West. The LTSWMP explains how the design and standard operating procedures (SOPs) will reduce pollutants inherent with this site. It is expected to be dynamic and allowed to be modified when SOPs and facility systems do not function properly. The LTSWMP includes an inspection element that is required to show performance, but it is also designed to collect the information necessary to warrant updates and improvements. An inspection log for this site will be posted on the City’s Stormwater page.
City staff does not expect development to do more than the City itself is doing; therefore, the Riverton Public Works Facility LTSWMP should stand as a model for development. City staff will use this LTSWMP as a benchmark when reviewing new LTSWMPs created for proposed developments. However, the City also encourages innovation in designs, SOPs, and best management practices (BMP) that are more efficient at reducing pollutants specific to your property. But staff must require the use of the LTSWMP template to create an environment of manageability and equality among all property owners. The LTSWMP includes an agreement that is recorded on the property. When changes to the LTSWMP are desired and warranted and the agreement remains unchanged, the revision may occur at staff level and amended at the Salt Lake County recorder’s office by the City.Please understand that the future may bring new EPA regulation and subsequent City ordinances, which might translate to LTSWMP template updates. The City is committed to operating in an environmentally-responsible manner and hopes that you see the vision also.
