Comprehensive Storm Water Management Planning
Our Water Resources Group is familiar with a wide variety of accepted storm water management models as well as many of the local methodologies adopted by municipalities and watershed districts. We routinely customize both design methods and documentation to address specific client needs, such as traditional Rational Methodology and U.S. Corps of Engineers, Soil Conservation Service or Environmental Protection Agency models.
Our team works closely with you to identify the expected level of flood protection and potential project and regulatory constraints. Using extensive computer analysis, our designers review various alternatives including traditional storm sewer piping, surface drainage channels, detention basins, inlet and culvert control structures, sedimentation basins, low impact development, rain gardens and similar facilities to assist the client in selecting a storm water management system that effectively addresses the project objectives.
Bolton & Menk has experience in preparing comprehensive Storm Water Management Plans (SWMP) in the seven county metropolitan area where it is mandatory for communities to include approved SWMPs in their comprehensive plans. The success of these plans is based on early and ongoing communication with the various review agencies and water management organizations having jurisdiction in the area. The final document often includes recommended ordinance revisions, construction details, and best management practices that are intended to facilitate the improvement of the city’s runoff quality.
Although Greater Minnesota cities are not required to develop a SWMP, many cities have opted to have them. This is because SWMP are excellent planning tools used to find ways to accommodate growth, addressing existing flooding problems, in addressing NPDES Phase II storm water permitting requirements and in preparation for Total Maximum Daily Load (TMDL) limits associated with downstream impaired waters. Based on the rapidly growing list of impaired waters in Minnesota, it is likely that most Greater Minnesota cities will need to implement a TMDL as a means of addressing pollutants causing a downstream impairment. The storm water modeling information generated in our SWMPs can be used to address all of these real and pending issues.
Our involvement in storm water planning includes experience with the administration and public input process for several common storm water project financing methods: assessments, storm water utilities, tax districts, county and judicial drainage systems, highway/state aid system funding, and emergency grant/loan programs.
