What is a Utah LTSMP?
What is a LTSMP in Utah?
A LTSMP is a Long Term Stormwater Management Plan, which is a document that describes how post-construction stormwater runoff from a regulated site will be managed and controlled to prevent or minimize potential impacts to water quality and quantity. It is sometimes referred to as a LTSWMP. A LTSMP is required for certain types of development projects in Utah that have the potential of polluting stormwater after construction is complete. A LTSMP is also required for projects that are located within a sensitive area, such as a watershed, a wetland, or a floodplain.
A LTSMP is different from a SWPPP, which is a Stormwater Pollution Prevention Plan. A SWPPP is a document that describes how construction activities will be conducted to prevent or minimize erosion and sedimentation, and to prevent or reduce the discharge of pollutants from the construction site.
A LTSMP is a post-construction plan, while a SWPPP is a pre-construction and during-construction plan. A LTSMP is designed to provide long-term management of stormwater runoff, while a SWPPP is designed to provide short-term protection of stormwater runoff. A LTSMP is submitted to the local jurisdiction for approval, while a SWPPP is submitted to the Utah Division of Water Quality (DWQ) for authorization.
A LTSMP typically includes the following elements:
A site map that shows the location and boundaries of the site, the drainage areas, the stormwater conveyance systems, the stormwater management facilities, and the receiving waters.
A description of the site conditions, such as the land use, the soil type, the topography, the vegetation, the hydrology, and the climate.
A description of the stormwater management objectives, such as the design storm, the peak discharge, the runoff volume, the water quality, and the maintenance requirements.
A description of the stormwater management practices, such as the structural and non-structural controls, the best management practices (BMPs), the low impact development (LID) techniques, and the green infrastructure (GI) strategies.
A description of the operation and maintenance procedures, such as the inspection, monitoring, reporting, and recordkeeping activities, the responsible parties, the schedules, and the costs.
A description of the legal and institutional arrangements, such as the ownership, the easements, the agreements, the permits, and the enforcement mechanisms.
A LTSMP is a comprehensive and customized plan that is tailored to the specific site and its stormwater management needs. A LTSMP is intended to optimize the stormwater runoff and reduce the potential impacts to the environment and the public health and safety. A LTSMP is a collaborative and cooperative effort between the developer, the designer, the contractor, the local jurisdiction, the DWQ, and the public.
