WHEREAS, the Landowner is the owner of certain real property located in Dakota
County, Minnesota legally described in Exhibit A attached hereto ("Property"); and
WHEREAS, the Landowner has applied to the City for an amendment of the
Landowner’s conditional use permit to expand the building and parking area locate on the
Property;
WHEREAS, as a condition of the CUP Amendment, the City requires that the
Landowner provide for detention/retention of stormwater within the confines of the Property
pursuant to the plan attached hereto as Exhibit B (the “Plan”) which are necessary for the health,
safety, and welfare of the residents of the City of Lakeville, Minnesota and enter into this
Agreement; and
WHEREAS, the City requires that on-site stormwater management/BMP facilities
(“Stormwater Facilities”) be constructed and adequately maintained by the Landowner, its
successors and assigns; and
WHEREAS, the Landowner shall grant to the City an easement for access, drainage and
utility over a portion of the Property (the “Easement Area”) legally described on Exhibit C
attached hereto and depicted on Exhibit D attached hereto to comply with work required under
the terms of this Agreement.
NOW, THEREFORE, in consideration of the foregoing premises, the mutual covenants
contained herein, and the following terms and conditions, the parties hereto agree as follows:

Therefore, it is critical to maintain or enhance the infiltrating properties of the soils within these areas.Options to accomplish include the following:(1)Limit construction traffic within these areas as much as possible to avoid compacting the soils in these areas.(2)Use a toothed bucket backhoe to excavate soils. Use off road trucks to haul and dump soils to other parts of the site.(3)Use a bucket and backhoe to place soils (where fill is required).(4)Use a toothed bucket for rough grading.(5)Use manual labor for finish grading.(6)Do not use equipment on the surface of the areas as this will compact the soils. Minimize smearing of the soils with mechanical equipment.(7)No stockpiling of soils or other materials shall occur within the areas.b.Rough grade the infiltration area to specified tolerances and in accordance with the procedures listed in Section 31 00 00 Earthwork.(1)Access the area at a single location to minimize disturbance to the surrounding areas.(2)Use of self propelled equipment shall be limited within the Infiltration Area. Self propelled equipment will compact the soils and adversely affectinfiltration. As much as possible, access work in the infiltration ares from the edges, outside of the infiltration area limits.(3)Use a backhoe with long reach ability for final excavation that reaches from outside the areas).(4)Remove all debris by hand.(5)Scarify the existing underlying soils as specified in Section 31 00 00 Earthwork.c.Provide final grading and final restoration at the Infiltration Area, including:(1)Access the areas at a single location to minimize disturbance to the surrounding areas.(2)Use of self propelled equipment shall be as described above.
