Please note the <br />following conditions imposed by the Managers, which are also listed on the back of the permit. <br />1. The applicant shall obtain approval from the City of Lake Elmo Engineer for the proposed <br />increase in peak stormwater runoff rates to the storm sewer in 39th St. N. east of Wildflower <br />Drive. <br />2. Updated plans shall be submitted to the VBWD Engineer for approval with a note or detail to <br />state that if soils that are not conducive to infiltration are discovered within the infiltration <br />basin during construction, these soils need to be removed and replaced with soil material that <br />will infiltrate at the design rate. The permit is not valid until the VBWD Engineer has approved <br />the submittal. <br />3. This permit is not valid until a maintenance agreement in the general format of Appendix A of <br />the VBWD Rules is submitted to and approved by the VBWD Attorney. The maintenance <br />agreement must include a monitoring plan and details on maintaining the stormwater <br />management facility. <br />4. Prior to permit closeout, a plan for post-project management of chloride use shall be <br />submitted. At a minimum, the plan shall include the following: <br />a. Designation of an individual authorized to implement the chloride-use plan <br />b. Designation of an MPCA-certified salt applicator to implement the chloride-use plan for <br />the site <br />5. Updated plans shall be submitted to the VBWD Engineer for approval to revise the discharge <br />elevation of FES-300 to be at the bottom of the infiltration basin rather than up the slope to <br />mitigate potential erosion issues. The permit is not valid until the VBWD Engineer has <br />approved the submittal.
