Stormwater Management
no. 17

Minimize the volume of and pollutants in rainwater runoff by maximizing green infrastructure.
  Best Practice Action 3      [ 1 2 3 4 5 6 ]       [all actions]

Adopt by ordinance one or more of the following stormwater infiltration/management strategies:

a.  A narrower streets provision that permits construction of 22-foot roads for public, residential access and subcollector streets (with fewer than 400 average daily trips).
b.  For sites less than one acre, retain the water quality volume of 1.1 inches of runoff from all impervious surfaces for new and fully-redeveloped construction sites.
c.  For non-MS4 permittees, adopt an illicit discharge prohibition rule or ordinance and an erosion and sediment control ordinance.
  • North St. Paul, working with the Ramsey-Washington Metro Watershed District and Barr Engineering, identifies 22-foot streets with parking allowed on one side as workable in its 2011 Living Streets Plan. The National Association of City Transportation Officials Street Design Guide states: "Lane widths of 10 feet are appropriate in urban areas and have a positive impact on a street’s safety without impacting traffic operations. For designated truck or transit routes, one travel lane of 11 feet may be used in each direction. In select cases, narrower travel lanes (9–9.5 feet) can be effective as through lanes in conjunction with a turn lane." Cost-savings of 3.4% ($170,000) were projected for a 2015 Brooklyn Park street repaving and narrowing of 32' streets to 30' streets.
  • The Urban Street Stormwater Guide (National Association of City Transportation Officials: 2017) provides cities with national best practices for sustainable storm water management in the public right-of-way. See also the related Light Imprint approach to stormwater management and low-impact development that is rooted in the New Urbanism, which promotes traditional neighborhood design and is scaled for the different density zones of the urban-to-rural transect. A city-sponsored Adopt-a-Drain program may be one useful management effort.
  • Stormwater and Erosion and Sediment Control Ordinance in Minnesota's 2009 Model Ordinances for Sustainable Development.
At least one ordinance in place (MS4s must achieve a 2- or 3-star rating). Report a "skinny street" project that decreases imperious street surface as a part of routine street reconstruction under action 11.2
Two ordinances in place.
Three or more ordinances in place.

Golden Valley

Date action report first entered:   04/25/2017
Date of last report update:   11/16/2018
Year action initially completed:   2015
Action completed after joining GreenStep?   No

Implementation details:
Golden Valley code (chapter 107) requires stormwater runoff rates be limited to pre-project rates for the 2-year, 10-year and 100-year, 24-hour precipitation events. It additionally prohibits anyone from causing illegal discharge into the stormwater system unless they get authorization from a National Pollutant Discharge Elimination System (NPDES) point source permit obtained from the Minnesota Pollution Control Agency. Public and private street width proposals between 24- and 26-feet are consistently approved by Golden Valley staff, and some as narrow as 18-feet have been approved. Non-residential development and redevelopment projects between one-half acre and one acre where stormwater is being discharged to a surface water without being routed first through a stormwater management facility or best management practice (BMP) must include stormwater management BMPs to protect and improve water quality. Developers are required to meet the erosion and sediment control requirements specified by current regulatory rules in the Stormwater Management ordinance, consistent with MPCA’s Construction Stormwater Permit.

Action completed after joining GreenStep?   No

Implementation details:
Under state and federal rules, the City of La Crescent has been classified as a Municipal Separate Storm Sewer System (MS4) community. As such, the City has developed a Storm Water Pollution Prevention Plan (SWPPP) designed to develop, implement and enforce a Storm Water Pollution Prevention Plan (SWPPP) that is intended to minimize the discharge of pollutants from its storm sewer system in order to protect the water quality of the receiving waters in accordance with the Federal Clean Water Act (CWA) and its amendments. This Storm Water Pollution Prevention Plan is a local plan that has been prepared with the purpose of meeting the requirements of the Federal National Pollutant Discharge Elimination System (NPDES) Phase II permit. Best Management Practices (BMPs), including education, maintenance, pollution control techniques, system designs and engineering methods as well as local provisions deemed appropriate, are to be used to meet the minimum requirements of the NPDES Phase II permit. The La Crescent SWPPP is a plan to meet each of the six Minimum Control Measures (MCM) described by the permit. The tasks described are not one-time efforts; they will continue throughout the permit period and beyond to maintain water quality. They are: Public education and outreach Public participation/involvement Illicit discharge, detection and elimination Construction site runoff control Post-construction site runoff control Pollution prevention/good housekeeping

Shoreview

Date action report first entered:   05/01/2013

Implementation details:
Yes, street width construction is considered on a case by case basis during planning and reconstruction of streets. Shoreview has one pervious concrete neighborhood with a street not wider than 20 feet, due to mature trees and small right of way challenges. The City is usually not interested in building roads wider, as they are more expensive to both build and maintain (plow, sweep, patch, etc). Construction of streets is outlined in Municipal Code Section 402. Watersheds have volume reduction and infiltration requirements which the City meets in our projects. Shoreview's illicit discharge ordinance is found in Section 209.060 of the Municipal Code.

Bloomington pending

Date action report first entered:   01/31/2018
Date of last report update:   01/31/2018
Action completed after joining GreenStep?   No

Implementation details:
a) The standard city street width is 32-feet. However it is common practice within the city that when conditions allow (low ADT, no parking issues, bike lanes, etc) street reconstruction projects will reduce street width to the extent practical. There is nothing in city code that prevents the city from reducing street widths from the standard 32-foot design to 22- or 24-foot widths. C)City code section 11.31 has language regarding the use of sewers and section 12.03 has language regarding Public Nuisances and prohibiting the discharge of specific items into a street, storm sewer, or water resource. Updated ordinances in 2015 to more clearly prohibit non-stormwater discharges, define additional terms, and more clearly outline exemptions to the discharge prohibition. In developing the updated language staff reviewed the EPA model ordinance to prepare an ordinance properly prohibiting non-stormwater discharges.
