Roseville Public Works, Environment and Transportation Commission Agenda Item Date: January 24, 2017 Item No: 7 Item Description: Stormwater Management Standards: Parking Lots Background: The City of Roseville has developed specific requirements that apply to development and redevelopment projects. These standards are intended to help achieve the water resource goals of the City's Comprehensive Surface Water Management Plan (CSWMP) and help the City maintain compliance with the National Pollutant Discharge Elimination System (NPDES) municipal permit program. These standards highlight important aspects of the requirements for storm water quality, discharge rate and volume control, erosion control, and illicit discharge. To accomplish the goals of the CSWMP, it is important that the City have consistent approaches to evaluating proposed development and redevelopment projects. Currently the City has a different requirement for when a permit is needed for parking lot pavement projects than the watershed districts. There is also some area for interpretation within our requirement of when a permit is required. As language within the Stormwater Management Standards is revisited, staff would also like to take the time to have a discussion and get feedback about how parking lot projects are viewed going forward. Parking lots within the City produce a large amount of stormwater and contribute to local flooding, general drainage, and water quality problems. General drainage issues arise from the City's storm sewer network being undersized for the stormwater created during rain events. When parking lots are resurfaced (all pavement removed and replaced), different stormwater bmp's could be installed to positively affect the problems listed above. However these BMP's will have to be paid for and maintained by the City, the private entity, or a combination of the two. Staff prepared a presentation to highlight the goals, problems within the City in regards to drainage, and different scenarios that our Stormwater Management Standards could be adapted to (with pro's and con's for each). Recommended Action: Receive presentation and provide feedback. Attachments: A. PDF of the PowerPoint that will be presented at the meeting.
