Attachment E RSI*SFaC+E Storm Water Management Standards 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 Surface Water Management Plan (SWMP) 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. These standards do not replace or supersede City ordinances, watershed district regulations, state and federal rules or permits required for the project. For a more detailed listing of requirements see the specific policies of the City's SWMP and the applicable City ordinances, or consult with City staff on your specific project. To accomplish the goals of the SWMP, it is important to the City to have consistent approaches to evaluating proposed development and redevelopment projects. Therefore, all hydrologic, hydraulic and water quality analysis must be prepared and submitted in a format that will allow for a timely and efficient review by City staff. Project designers and/or developers are encouraged to schedule and complete a pre-design meeting with the City before any data will be accepted. The purpose of the meeting is to specifically address approvals and permits, pond requirements, trunk storm drain analysis, wetland impacts, water quality treatment, erosion control and discharge to lakes and sensitive wetland resources. 1) General a) Erosion control standards apply to all land disturbance activity unless specifically exempted by the definition of the term "land disturbance activity" in the City's Erosion and Sedimentation Control Ordinance(Roseville City Code Chapter 803.04). b) The City's water quality treatment requirements apply to projects which result in twenty-one thousand, seven hundred eighty (21,780) square feet or more of disturbed area or five thousand (5,000) square feet or more of new or reconstructed impervious surface, and c) The City's rate/volume control requirements apply to all projects, and d) Projects conducting mill and overlay or other surface pavement treatments, where aggregate base is left undisturbed, on existing impervious areas are exempt from the City's water quality treatment and rate control requirements. However, requirements must be met if the project impacts the base and/or sub-base materials for 21,780 square feet or more of disturbed area. e) Projects in a Shoreland, Wetland Protection or Storm Water Management Overlay District may have additional requirements which are defined in Roseville City Code Chapter 1017. f) Any work within a wetland, surface water, or Federal Emergency Management Agency (FEMA) designated floodplain may require permits to be obtained from, but not limited to the City, watershed district, Department of Natural Resources (DNR) and Army Corps of Engineers. All applicable permits for the specific project must be obtained prior to commencing land disturbance, construction, grading, clearing, or filling activities. g) The Applicant shall submit the information listed in Section 8 of these Standards to the City for review. 12/11/14
