RE: Business Park Grading
Background:
The City works in conjunction with WAG Trust to create buildable lots within the Business Park.
This partnership has enabled many businesses to locate in Cottage Grove through the utilization
of TIF to provide for the necessary infrastructure (grading, streets, and utilities) for the park. The
latest business to take advantage of this partnership was AGCO with the expansion of their
facility in 2015. As part of the mass site grading for AGCO additional material was generated;
the intended excess was to be used on the adjacent property to create pad-ready sites.

Discussion:
As part of the Council's goal of "Positioning for Growth," there is a need to create more pad-
ready sites in the Business Park that can be cost effectively served with sanitary sewer and
water. In order to compete in the marketplace for new business park companies, it is important
to have various sizes of lots available for the end user. The area shown below is planned to be
graded to create those pad sites.

As part of the grading, clearing of the trees in the center of the site will be done, a regional
stormwater basin will be created, and marketable sites from 3 to 17 acres will be created. Staff
will also be pursuing shovel-ready status for the site.

All requirements listed in Part III of the Permit for the design of the permanent stormwater management system and discharge
have been included in the preparation of this SWPPP.These include but are not limited to::
1. The expected amount,frequency,intensity,and duration of precipitation.
2. The nature of stormwater runoff and run-on at the site
3. Peak flow rates and stormwater volumes to minimize erosion at outlets and downstream channel and stream bank erosion.
4. The range of soil particle sizes expected to be present on the site.
