Building:

must be obtained prior to construction.
4. Drainage water collected from (any portion of) the building, or mechanical equipment
may not flow across a public walking surface (sidewalk).
5. Detailed occupancy related requirements will be addressed when complete building plans
are submitted.

along the existing parking spaces
Engineering:
1. An access agreement with the adjacent property is required for the shared driveway on
the east side of the subject property.
2. A hydrant is required. The location of the fire hydrant must be approved by the Fire
Chief.

must be removed or abandoned.
Planning:
1. The applicant shall enter into a site plan agreement prior to receiving a building permit.

sign installation.
Water Resources:
1. The applicant shall apply for and receive a General Permit Authorization to Discharge
Stormwater Associated with Construction Activity Under the National Pollution
Discharge Elimination/State Disposal System (NPDES Construction Permit) prior to the
issuance of a building permit or any earth disturbing activities.
The plan submittal must also include a detail of the infiltration basin consistent with the
Minnesota Stormwater Manual prior to issuance of a building permit. This detail must
include any soils corrections, basin protections and planting plans and schedules in
addition to other necessary design elements.
3. After construction, the infiltration basin shall be tested by a third party for permeability to
ensure that it is functioning per the stormwater modeling submitted by the applicant. The
infiltration basin must pass the permeability testing prior to an issuance of a permanent
certificate of occupancy. Or if agreed to by both parties, the city may confirm rates in-
house with their Modified Phillip -Dunn infiltrometer.

4. The applicant shall prepare an operations and maintenance manual specific to the
infiltration feature including anticipated inspection schedule, routine maintenance and
frequency of said maintenance and supply a copy to the city prior to issuance of a
building permit.
5. All erosion control shall be installed and inspected prior to initiation of site grading
activities.
6. The site plan must comply with Riley -Purgatory -Bluff Creek Watershed District,
RPBCWD, rules for erosion prevention and sediment control and storm water

dewatering), Riley -Purgatory -Bluff Creek Watershed District) and comply with their
conditions of approval.
I have requested from you an engineer's estimate of the costs for the infiltration basin and site
drainage and erosion control measures as well as site landscaping. Once I have these estimates, I
will be able to complete the site plan agreement, which must be executed and required securities
submitted prior to any development of the site.
If you have any questions or need additional information, please contact me at (952) 227-1131 or
