related parking expansion and site improvements, in accordance with the plans received by
the city on August 11, 2011, except as may be amended by this resolution.
2. Approval of the site plan amendment is contingent upon separate City Council approval of a

3) Identify the wetland boundaries on the grading plan.
4) Indicate normal water levels (NWL) and high water levels (HWL) for existing
wetlands. Indicate NWL, HWL, and emergency overflow elevations (EOF) for
storm water treatment areas.
5) Identify location of the Bio -Retention Area — Filtration Facility detail shown on
Sheet C403.
6) Identify limits and scope of ditch grading for the culvert along 36t1i Avenue.
7) Clarify the extent of wetland impacts for the project. Identify impacts to wetland 43
associated with fire lane constriction. Cumulative impacts for the project must be
less than 1,000 square feet to qualify for a de minimus exemption. If wetland
impacts exceed 1,000 square feet, a wetland replacement plan is required.
8) Retaining walls that exceed four feet in height require a fence and also require a
building permit. Indicate top and bottom of wall elevations on the plans.
9) City Standard Plate STRT-8 shall be used for the entrance to 36t1i Avenue.
10) Provide spot elevations for the service delivery drive on the north side of the
building.
11) The lowest floor elevations for the building must be at least 2 feet above the HWL
for adjacent storm water treatment facilities and at least 18 inches above the EOF on
the west side of the building.
b. Utility plan:
1) Identify the outlet for the trench drain at the delivery entrance to the building.
Connections to the sanitary sewer system are prohibited.
2) Move drain tile from under the building along the service delivery driveway.
3) Provide a video inspection report for all new storm sewer lines.
4) Identify stricture dimensions and casting numbers for each stricture shown on the
storm sewer stricture schedule.
5) Identify invert elevations, pipe size, pipe length, aprons, and rip rap size and quantity
for the culvert under the 36t11 Avenue entrance, as well as for the culvert under the
fire lane.
6) Identify top of casting and invert elevations for sanitary sewer manholes.
7) Confirm fire flow requirements are met by using the existing 8 -inch water main in
36t1i Avenue. If fire flow requirements cannot be met, a secondary connection to the
existing 12 -inch main in East Medicine Lake Boulevard may be required.
8) Replacement of existing water main will require a temporary water plan to provide
continuous service to the building during constriction, since there is only one feed
point on 36'11 Avenue. Consider adding a second service connection on 36t1i Avenue
west of the existing hydrant labeled as (BM41).
9) A pressure test and bacteriological test is required for the new water main before
placing it into service.

2) Demonstrate that post -development rates of runoff are less than pre -development
rates for the 10 -year and 100 -year frequency rainfall events.

and storm sewer as-builts for the site prior to the release of any financial guarantees.
