Report Prepared By: Benjamin J. Quaas, P.E. Registration Number: 59732 Report Reviewed By: Nicholas P. Adam, P.E. Registration Number: 43856 REHDER & ASSOCIATES, INC. Civil Engineers & Land Surveyors 3440 Federal Drive, Suite 110 Eagan, MN 55122  651-452-5051  www.rehder.com NARRATIVE Project Summary The proposed plan is the construction of 2 office/warehouse buildings and associated site improvements on an undeveloped lot located at the southwest corner of Hwy 5 and Audubon Road in Chanhassen. The site area is 28.34 acres with a post construction impervious area of 18.25 acres (64.4% coverage) and a disturbed area of approximately 27.9 acres (98%). Requirements City of Chanhassen and Riley-Purgatory-Bluff Creek Watershed District Requirements: • Volume control for 1.1-inch of runoff from the new and reconstructed impervious areas. 0.55-inch for restricted sites. • Water quality to meet 60% phosphorous (TP) and 90% total suspended solids (TSS) removal as well as no net increase in TSS or TP loading. • Rate control matching the existing rates the 2, 10 and 100-year events as well as the 100-year, 10-day snowmelt event. Existing Conditions The existing site is undeveloped and consists of meadow grass and trees including 6 delineated wetlands. There is an existing right-of-way that is platted through the site with McGlynn Road stubbed into the middle of the site. Runoff from the site drains in all directions off of the site with a majority of it draining to the west/northwest. Proposed Conditions The proposed improvements consist of 2 office/warehouse buildings and associated parking areas and loading dock areas. As part of the development, McGlynn road will be removed back towards the east and a cul-de-sac constructed per City standards. The development will remove 4 of the 6 wetlands on the site with one of the wetlands being an incidental wetland and thus the purchase of wetland banking credits will only be required for 3 of the 4 wetlands. Per the geotechnical report, soils on the site are Type ‘D’. REHDER & ASSOCIATES, INC.

The proposed infiltration basins are sized for 1.1-inch of runoff from the new and reconstructed impervious areas. Pre-treatment to the basins consist of sump structures with “THE PRESERVER” device installed and a Rain Guardian device at the curb opening to Infiltration Basin 4. The storm water management system is capturing and treating 99.8% of the 18.51 acres of impervious area from the site. There is 0.2 acres of reconstructed impervious area in the Right-of-Way that is not being treated due to the relocation of the cul-de-sac. We are unable to capture this area and direct it to one of the infiltration basins. There are also complications of directing runoff from the Right-of-Way into a private storm water treatment basin. However, with the removal of the existing street and cul-de-sac to the west we are reducing the amount of impervious area to the City’s storm sewer system by 0.23 acres and thus reducing the volume and quantity of pollutants. Rate Control The existing and proposed 2-, 10-, and 100-yr frequency discharges from the site are summarized in the table below.

Restricted sites shall provide volume control in accordance with the following sequence: (a) Abstraction of at least 0.55 inches of runoff from the site impervious areas or (b) Abstraction of runoff onsite to the maximum extent practicable or (c) Off-site abstraction in the watershed. However, additional infiltrometer testing was performed at the proposed grades of the basins which produced infiltration rates ranging from 0.06 in/hr to 1.8 in/hr (see attached testing results). Thus the proposed infiltration basins have been designed to provide abstraction for 1.1 inches of runoff from the impervious areas draining to the basins. The designed abstraction performance for the site is summarized in the table below. Basin 1.1" Vol. Required Volume Provided (cu.ft.) (cu.ft.)

There are 4 wetlands and 1 watercourse being filled as part of the development and the table below summarizes the compensatory storage provided. Due to the wetlands being filled/removed, compensatory storage cannot be provided within the floodplain of the wetlands and thus we are requesting a variance.
