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. Attached for reference: Exhibit 1: Aeration Piping Modifications—Construction Narrative, Timeline and Pictures Exhibit 2: Outfall Repairs—Construction Narrative, Timeline and Pictures Exhibit 3: Summary of Work Exhibit 4: Air Photo with Property Lines Exhibit 5: Title Sheet— Project Areas(GI1) Exhibit 6: Demolition Plan and Profile (CD1) Exhibit 7: Site Plan and Profile (CU1) Exhibit 8: Piping Sections—Aeration Piping Elevations (MP2) Exhibit 9: Tree Survey Exhibit 10: Tree Replacement Report—Kathy Widin, April 6, 2015 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 (L e., 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 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.

Resumed placing coffer dam and the plume was contained by BMP's. However,when the Plant outfall was resumed at 12:50,so did the plume and work was suspended by MCES. A third silt curtain was installed at the conveyance discharge. Isensee and Adams were on site to observe. BMP's were maintained. 3/16/15 Set up sediment capture area (STA 4+40)with sediment sock,staked silt fence, and hay bales around the perimeter. A sump pump was installed within the trench box. Temporary road construction continued. Johnson and Isensee were on site to deliver a stop work order to take effect the next day. BMP's were maintained.
