RE: Oak Park Heights—St. Croix Valley Wastewater Treatment Plant—
Upgrades to Aeration Piping and Outfall Piping —Conditional Use
Permit
FILE NO: 236.02— 15.02
BACKGROUND
Kyle Colvin, of the Metropolitan Council has made application for a Conditional Use
Permit (CUP) to allow for upgrades to the aeration and outfall piping at the St. Croix
Valley Wastewater Treatment Plant at 6163 St. Croix Trail North. The project will
consist of demolition of the existing piping and installation of new piping and related
facilities for aeration and the outfall to the St Croix River. Trees will be removed as part
of the outfall improvements.
The property is zoned I, Industrial District. The wastewater treatment plant is a
permitted use within this district. The property is also in a River Impact District which
requires a CUP for significant exterior changes to the facility.

ISSUES ANALYSIS
Project Description. The description of the projects and timelines for the construction
is found in detail in Exhibits 1 and 2. A summary of the project is as follows:
Aeration Piping:
1. Demolition and abandonment of existing above ground and below ground
aeration piping and appurtenances.
2. Air pipe penetration through the roof of the existing blower building.
3. The installation of new above ground welded stainless steel aeration
piping, fittings, valves and structural supports.
4. The installation of three new air flow meters and three new actuated
valves including conduit, wiring and connections to the existing control
system.
The update to the aeration system was completed in December of 2014.
Outfall Repairs:
1. Demolition of existing below ground outfall piping and appurtenances.
2. Installation of new RCP outfall piping, manhole and riprap.
3. Restoration of vegetated areas, asphalt, concrete surfaces and other
areas affected by the work.
4. Conformance with requirements set forth by permitting agencies.
The update to the outfall is expected to be completed by the middle of April, 2015.
Comprehensive Plan. The Comprehensive Plan designates this area as industrial
land use. The use of the property for a waste water treatment plant is recognized as
industrial land use consistent with the maps and policies of the plan.
Zoning Ordinance. The site is zoned I, Industrial District in which facilities such as the
St. Croix Valley Wastewater Treatment Plant are a permitted use. The CUP is required
to allow for the construction in the River Impact District.
Trees/Screening. The Demolition Plan and Profile (Exhibit 6) indicates the trees that
have been removed as part of the improvements to the outfall piping. Kathy Widin, the
City Arborist has calculated a tree replacement requirement for the project at 96 inches
which is the equivalent of 48, 2 inch caliper trees. The Metropolitan Council will be
required to provide a tree replacement plan that will satisfy the requirement.
2
Lighting. City Staff has recognized that lighting at the wastewater treatment plant is
not compliant with the standard for full cut off fixtures. The Metropolitan Council has
agreed to do an inventory of their light fixtures and identify those that are not full cut off.
The existing fixtures could be shielded to meet the requirements or replaced with higher
efficiency fixtures that will be a cost savings. An inventory of the fixtures will be required
with a plan for replacement or retrofit.
Grading and Drainage. Any grading and drainage issues shall be addressed subject
to review and approval of the City Engineer and the Middle St. Croix Watershed
Management Organization.
Department of Natural Resources. The Department of Natural Resources (DNR) has
been notified of the request. The City has received no comment from the DNR on this
project.
Design Guidelines. There are no new buildings proposed as part of this project. The
Design Guidelines do not apply with this application.
Conditional Use Permit — River Impact District. The upgrades to the aeration
systems and outfall piping at the wastewater treatment plant are subject to a CUP under
the River Impact District. The Planning Commission should consider the environmental
issues and impacts of the proposed project in making its recommendation. The
conditional use permit criteria, found in Section 401.03.A.7 of the Zoning Ordinance, are
found as follows:
1. Relationship to the specific policies and provisions of the municipal comprehensive plan.
2. The conformity with present and future land uses in the area.
3. The environmental issues and geographic area involved.
4. Whether the use will tend to or actually depreciate the area in which it is proposed.
5. The impact on character of the surrounding area.
6. The demonstrated need for such use.
7. Traffic generation by the use in relation to capabilities of streets serving the property.
8. The impact upon existing public services and facilities including parks, schools, streets,
and utilities, and the City's service capacity.
9. The proposed use's conformity with all performance standards contained herein (Le.,
parking, loading, noise, etc.).
Due to the location of the improvements in an industrial area, and the fact that the
facilities have been in place for a number of years and are now just being upgraded,
City Staff recognizes no issue with the improvements outlined with this project.
CONCLUSION AND RECOMMENDATION
Based upon the preceding review, City staff recommends approval of the CUP for
upgrades to the aeration and outfall piping at the St. Croix Valley Wastewater Treatment
Plant at 6163 St. Croix Trail North in the River Impact District subject to the following
conditions:
3
1. The Metropolitan Council shall be required to provide and implement a plan
that will satisfy the requirement for tree replacement subject to review and
approval of the City Arborist.
2. An inventory of building and site lighting shall be required with a plan for
replacement or retrofit to comply with Zoning Ordinance standards. The
freestanding and building lighting shall be brought into compliance with the
Zoning Ordinance and subject to review and approval of City staff within one year
of CUP approval.
3. Any changes to the grade or drainage associated with the project shall be subject
to review and approval of the City Engineer and the Middle St. Croix Watershed
Management Organization.
4. The City will not require conformance with the Design Guidelines for the project.
5. The plans are subject to review and approval of the Department of Natural
Resources and any other state or federal regulating agency, if applicable.
