The existing substation is deemed to be at capacity which will require a second transformer, switchgear and a new electric feeder line. The equipment upgrades include a new electrical equipment enclosure. The fenced area will be expanded to accommodate the additional equipment. The property is zoned B-4, Limited Business District in which electrical substations with open and outdoor equipment is a listed conditional use. The original Conditional Use Permit was approved by the City in 1990, and the fence for the facility was approved in 2007. Attached for reference: Exhibit 1: Project Narrative from Xcel Energy— Brian Sullivan Exhibit 2: Proposed Plan Exhibit 3: Topography Layout Exhibit 4: Contour and Grading Layout Plan Exhibit 5: Contour and Grading Layout Sections Exhibit 6: Contour and Grading Layout Sections Exhibit 7: Contour and Grading Layout Details Exhibit 8: Contour and Grading Layout Details Exhibit 9: Contour and Grading Layout SWPPP Plan Exhibit 10: Electrical Layout, 115KV Sections Exhibit 11: Electrical Equipment Enclosure Plan Exhibit 12: Tree Inventory Exhibit 13: Report of the City Arborist Exhibit 14: Report of the City Engineer ISSUES ANALYSIS Project Description. Excerpts from the project narrative are as follows: Project Summary: Xcel Energy is proposing to expand the existing Baytown electrical substation. The expansion will provide reliable electric service to the businesses and residential customers in Oak Park Heights and the surrounding communities in Washington County. The existing substation as configured is at capacity and the customers it serves could be subject to prolonged outages if the upgrades are not made. Xcel is requesting an amendment to the CUP to allow the proposed improvements. Site: The substation property is approximately 1.5 acres in size and is currently used as a distribution electric substation. Xcel is proposing to upgrade the existing equipment and add additional equipment. The property includes a depression behind (east) the substation that will be used for storm water management purposes. A wetland investigation verified that there are no wetlands on the property. The surrounding land uses are commercial in nature. Goodwill has a retail facility to the east of the substation with an access drive and a monument sign to the south. Also to the south are existing electric transmission power lines that provide the power for the substation. Project Overview: Xcel Energy has recently conducted a study of the electrical system in Oak Park Heights. The study identified several areas in the electric grid that need to be upgraded. The study identified that there is a risk of an overload of the system and power may not be restored immediately during periods of peak load activity. To reduce the risk of a major outage a second transformer, switchgear, and a new electric feeder line will be installed. Equipment upgrades include a new electrical equipment enclosure which has among other things enhanced monitoring capabilities. Landscape Plan: The proposed landscape plan is attached. The plan includes a mix of deciduous and evergreen trees that will provide screening from surrounding uses. Because of clearance requirements below power lines, plant material below the power lines has been limited to species that grow to a height of 15 feet. Xcel Energy is proposing to 2 enclose the expanded facility with the same wood privacy fence used to screen the original substation. Security and Design Issues: Per the National Electric Safety Code, the substation will have an 8-foot-tall wood security fence surrounding the facilities. The substation is also equipped with alarms that are continually monitored by our operations center. Security lighting is provided and is not activated unless for emergency repairs. Access and Parking: Access will be via an existing drive off of Nova Scotia Avenue North. As noted earlier this is an unmanned facility. Parking will be provided within the substation facility and the access drive to the substation. Comprehensive Plan. The Comprehensive Plan designates this area as commercial land use. The substation is consistent with this designation. Zoning Ordinance. The site is zoned B-4, Limited Business District in which electrical substations with open and outdoor equipment is a listed conditional use. The original Conditional Use Permit was approved by the City in 1990, and the fence for the facility was approved in 2007. The fence is compliant with setback requirements. The criteria for review of the amended Conditional Use Permit are found later in this report. Parking and Traffic. The substation does not have employees. Parking is available within the substation facility and on the access drive to the substation. Lighting. The facility is not proposed to be lit. Security lighting is provided but is not activated unless needed for emergency repairs. Any non-security lighting, if installed, shall be full cut off and comply with the Zoning Ordinance requirements. Trees/Screening. Trees will be removed to accommodate the larger area required for the substation upgrades. A landscape plan has been provided indicating the locations of new plantings. The tree removal and landscape plan is subject to review and approval of the City Arborist. Fence. The expanded area shall be enclosed with the same solid wall wood privacy fence used currently at the substation. 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. 3 Design Guidelines. An electric equipment enclosure will be located at the south side of the substation and within the fence enclosure. It will be 24 feet by 40 feet and 12 feet in height. Utility structures are not subject to Design Guideline review. Bayport Substation. It has been observed that the Bayport Substation in Oak Park Heights has nuisance issues that must be addressed. There is peeling paint on the primary building structure and lighting fixtures that are not full cut off. These issues will need to be addressed prior to allowing work on the Baytown Substation on Nova Scotia. Amended Conditional Use Permit. Electrical substations with open and outdoor equipment is a listed conditional use. The Planning Commission should consider the conformity, 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.). The expansion of the substation is consistent with the Comprehensive Plan and with present land uses. Due to the location of the substation in a commercial area, and the fencing and landscaping that has been provided, City Staff does not recognize any impact on the surrounding area. Electric distribution is important to the community residents and businesses. There will be not impacts to public services or the City's service capacity. CONCLUSION AND RECOMMENDATION Based upon the preceding review, City staff recommends approval of the application for an amended Conditional Use Permit to allow expansion of the Xcel Energy Substation on Nova Scotia Avenue, subject to the following conditions: 1. Any non-security lighting, if installed, shall be full cut off and comply with the Zoning Ordinance requirements. 2. The tree removal and landscape plan is subject to review and approval of the City Arborist. 4 3. The expanded area shall be enclosed with the same solid wall wood privacy fence used currently at the substation. 4. The City will not require conformance with the Design Guidelines for the project. 5. 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. 6. The Applicant shall address and correct the nuisance building conditions (peeling paint) as found on the primary building structure at the Bayport Substation. 7. The Applicant shall replace all building lighting fixtures on the primary building structure at the Bayport Substation with full cut off lighting. 8. No work is permitted nor shall commence at the Baytown Substation on Nova Scotia until the Bayport Substation is brought into compliance with the building conditions and lighting at the Bayport Substation.

The following includes my comments and/or recommendations: TREE INVENTORY The tree inventory provided is incomplete. A spreadsheet/table should also be included to correspond with the tree inventory provided. Attributes to include are as follows for each tree: Tree ID, species, size (in caliper inches), Remove/Protect, Notes. This information is needed to complete the tree replacement calculation. 1. Please clarify on the tree inventory provided the quantity of birch TBR. (The plan states TW 6" BIRCH TBR) 2. Specify the species for each of the pines. 3. Include the trunk size in caliper inches for all Amur maples. 4. Specify the quantity of Mugo pines included in the hedge. 5. Please reference the City of Oak Park Heights Landscape Guidelines for Developers in the Development Application Packet (Pages 11-15) and City Ordinance 1307. TREE CITY U.S.A. Once a completed tree inventory is submitted to the City, the tree replacement calculation can be computed and trees included in the landscape schedule will be figured into the tree replacement calculation (Number of Caliper Inches). TREE PRESERVATION PLAN 1. A tree preservation plan and diagram must be included to protect the trees listed in the inventory to be preserved which are in close proximity to the construction zone. 2. "No significant trees shall be removed until a tree preservation plan is approved by the City of Oak Park Heights," this must be included in the plans. LANDSCAPE PLAN Overall Landscape Plan The design includes a satisfactory selection of tree and shrub species to be planted on site. Two (2) evergreen tree species, an ornamental deciduous tree species, and five (5) shrub species, ((29) shrubs total). Plant species included in the plans are acceptable and will complement the site well. Landscape Schedule (Plant Schedule) 1. The planting list includes a variety of native or improved native cultivars, species that are hardy under local growing conditions, those that are relatively insect/disease free and fairly low maintenance. 2. The sizes of all replacement evergreen tree species, ornamental tree species, and shrubs are of minimum size requirements for replacement trees. Landscape Notes (Planting Specifications) 1. The plans must include the top two rungs of wire baskets on all B&B planting stock shall be removed once tree is in the planting hole, prior to backfilling. The landscape contractor for the project is required to plant all trees and shrubs according to the approved landscape plan. This will be inspected by the City Arborist after planting and any deviations from the detail will need to be corrected before the landscaping will be approved by the City. This needs to be included in the final submitted landscaping plans. 2. Trees proposed to be planted around buildings and high use common areas of the site should be nursery stock of high quality with straight central leaders and not "park-grade" trees. Please contact me if you have any questions regarding this landscape plan review. Please forward my comments to the development team for this project. 2 TREE CITY U.S.A.
