<br />CITY OF Ramsey
<br />Anoka COUNTY, MINNESOTA
<br />PROJECT LOCATION
<br />RESPONSIBLE PARTIES:
<br />The Contractor and Owner will be joint applicants under the MPCA's General Stormwater Permit for Construction Activity as required
<br />by the National Pollutant Discharge Elimination System (NPDES) Phase II program.
<br />The Contractor shall provide one or more trained Construction SWPPP Manager(s) knowledgeable and experienced in the application
<br />of erosion prevention and sediment control BMPs that will oversee the implementation of the SWPPP, and the installation, inspection

<br />The SWPPP Designer, Construction SWPPP Manager, and BMP Installer must have appropriate training. Documentation showing
<br />training commensurate with the job duties and responsibilities is required to be included in the SWPPP prior to any work beginning on
<br />the site. Training documentation for the SWPPP Designer is included on the Narrative sheet. The Contractor shall attach training
<br />documentation to this SWPPP for the Construction SWPPP Manager and BMP Installer prior to the start of construction. This
<br />information shall be kept up to date until the project NOT is filed.
<br />ADDITIONAL COMPENSATION
<br />Payment for all work associated with Erosion and Sediment Control shall be as described in the Project Manual. Unless otherwise
<br />authorized by the Owner no additional payment shall be made for any work required to administer and maintain the site erosion and
<br />sediment control in compliance with the Minnesota Pollution Control Agency (MPCA) - General Stormwater Permit for Construction
<br />Activity (MN R100001) including but not limited to inspection, maintenance, and removal of BMPs or addition of BMPs to
<br />accommodate Contractor phasing.
<br />DOCUMENT RETENTION
<br />Permittees must make the SWPPP, including all inspection reports, maintenance records, training records and other information
<br />required by this permit, available to federal, state, and local officials within three (3) days upon request for the duration of the permit
<br />and for three (3) years following the NOT.
<br />GENERAL STORMWATER DISCHARGE REQUIREMENTS
<br />All requirements listed in Section 5.1 of the Permit for the design of the permanent stormwater management system and discharge
<br />have been included in the preparation of this SWPPP. These include but are not limited to:
<br />1. The expected amount, frequency, intensity, and duration of precipitation.
<br />2. The nature of stormwater runoff and run-on at the site
<br />3. Peak flow rates and stormwater volumes to minimize erosion at outlets and downstream channel and stream bank erosion.
<br />4. The range of soil particle sizes expected to be present on the site.
<br />Permanent stormwater treatment systems for this project have been designed in accordance with the guidance in the MN Stormwater
<br />Manual in place at the time of bidding. Copies of the design information and calculations are part of this SWPPP and will be provided in
<br />digital format upon written request to the Engineer.

<br />DESCRIPTION OF CONSTRUCTION ACTIVITIES AND STORMWATER MANAGEMENT:
<br />Construction activities include: Site grading, sanitary sewer and water main extensions, temporary
<br />erosion and sediment control, and permanent stabilization.
<br />Storm water currently from the urbanized and undeveloped area is currently being routed to catch basins
<br />located along 142nd Ave NW and Xkimo St. NW and flow through storm drains into an existing pond
<br />located within Rivers Band park. The existing pond is located south of 142nd Ave NW and Waco st. NW
<br />intersection. The outlet of the pond is Rum River. The current pond size is in adequate to treat the current
<br />impervious area.
<br />After construction is complete storm water will be managed in a different pond area. The water will be
<br />routed through the catch basins located on 142nnd Ave. NW and Xkimo ST. NW and then routed through
<br />storm drains to the new biofiltration pond. First entering a wet sedimentation basin with a capacity of
<br />74,000 cubic feet, 5 feet deep, then entering the biofiltration basin. The pond will have a treatment
<br />capacity of 148,795 cubic feet.
<br />This project includes the following stormwater management BMPs: Biofiltration and wet sedimentation.

<br />3) Complete Site Grading.
<br />4) Add additional temporary BMPs as necessary during construction based on inspection reports.
<br />5) Ensure final stabilization measures are complete.
<br />6) Provide digital copy of all Field SWPPP Documentation including Inspection Reports and SWPPP Revisions to the Owner.
<br />7) Submit Notice of Termination (NOT) to MPCA. NOTE: The NOT must be submitted to MPCA before Final Stabilization is
<br />considered complete.
