7. The developer must prepare plans depicting an agreed-upon trail alignment and details for a
required bridge crossing and typical construction cross section for a lO-foot wide trail prior
to recording the final plat.
8. A wetland buffer with a minimum width of 16.5 feet shall be maintained around all
AglUrban wetlands. Wetland buffer areas shall be preserved, surveyed and staked in
accordance with the City's wetland ordinance. The applicant shall install wetland buffer edge
signs, under the direction of City staff, before construction begins and shall pay the City $20 per
sign. All structures shall maintain a setback of at least 40 feet from the wetland buffer edge.
The wetland buffer setback shall be shown on the plans.
9. All structures shall be set back at least 40 feet from the Bluff Creek primary zone. The first
20 feet of the setback from the primary zone cannot be disturbed. The plans shall be revised
to show the primary zone boundary, the 40-foot setback from the primary zone and the 20-
foot buffer area adjacent to the primary zone. If alteration is proposed within the 20-foot
buffer area adjacent to the primary zone, a variance will be required.
10. Signage for the Bluff Creek Overlay District should be posted at least every 300 feet along the
primary zone boundary.
11. The general notes on erosion and sediment controls are incomplete. A new SWPPP shall be
developed by the engineer for the site. The SWPPP shall be in place prior to applying for the
NPDES permit. Additional information regarding SWPPP requirements can be obtained
through the MPCA Storm Water Web Site. The SWPPP shall include all details, sequencing
of the project and seeding and mulching specifications.
12. Temporary and permanent erosion control plans and details shall be included in the plans.
Temporary erosion control may consist of type 1 mulch, as well as temporary and permanent
seed mixes. Erosion control blanket shall be installed on all slopes greater than or equal to
3:1. All exposed soil areas shall have temporary erosion protection or permanent cover year
round, according to the following table of slopes and time frames:
Type of Slope
Steeper than 3:1
10:1 t03:1
Flatter than 10: 1
Time
7 days
14 days
21 days
(Maximum time an area can
remain open when the area
is not actively being worked.)
These areas include constructed storm water management pond side slopes, and any exposed
soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter
system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man
made systems that discharge to a surface water.
13. Inlet controls are needed for all inlets throughout the project and shall be installed within 24
hours of inlet installation prior to casting. Filter fabric held down by steel plates with 12" of
%-inch rock over each cover may be used. Once casting of inlets takes place, inlet controls

16. The existing stormwater pond and areas downstream of the pond shall be protected from
sediment produced by the construction site. For example, if turbid water is found in the
stormwater pond, a plug could be placed in the flared-end section (PES) of the outlet
structure so sediment does not go off-site. Once settling of the sediment occurs, the water
could be slowly released.
17. Street cleaning of soil tracked onto public streets shall include daily street scraping and street
sweeping as-needed. Provisions for street cleaning shall be included in the SWPPP.

verifying that the proposed design meets the pond design assumptions and meets other
agency requirements (e.g. NPDES Phase 2 permit).

repair required for the utility service extension.

primary zone boundary.
