The area has experienced rapid growth in recent years. Completion of the St. Highway 312 project is anticipated to significantly drive more new growth until land use saturates. Technical analysis of the system targeted the need for a new electrical substation site within the target area while accounting for the presence of existing distribution feeders and transmission lines as well as existing and future load projections. The proposed site selected is a portion of unused property owned by M. A. Gedney and zoned Industrial Office Park District (lOP). The site is located north of an existing Xcel Energy switching station, east of the M. A. Gedney plant, west ofa St. John's Lutheran Cemetery and south of additional industrial office park property owned by MA Gedney. The specific legal description of the location under consideration is: Beginning in the Northwestern Quarter of Section 3, Township 115N, Range 23W which lies South 88 degrees 23 minutes 19 seconds East a distance of 2313 .94 feet from NW 3 monument located NW 3 in the Northwest Quarter of Section 3, Township 115N, Range 23W; Thence South 2 degrees 43 minutes 26 seconds West a distance of 193.29 feet. Thence South 0 degrees 18 minutes 10 seconds West a distance of 418.76 feet Thence South 57 degrees 57 minutes 21 seconds West a distance of 149.63 feet. Thence South 0 degrees 38 minutes 38 seconds West a distance of 171.50 feet. Thence South 62 degrees 53 minutes 44 seconds West a distance of35.77 feet. Thence North 1 degrees 5 minutes 52 seconds East a distance of 171.62 feet. Thence North 35 degrees 27 minutes 12 seconds West a distance of306.61 feet. Thence North 53 degrees 13 minutes 52 seconds East a distance of 427.59 feet to point of termination. The property consist of approximately 116,600 sq ft or about 2 .~ acres. Currently, a large portion ofMVEC's service area within Chanhassen and Eden Prairie is serviced by the Bluff Creek Substation or the Chaska Substation. Bluff Creek is a joint facility with Xcel Energy and the City of Chaska Public Utilities with MVEC having a secondary ownership position. Further expansion capabilities are extremely limited for MVEC within the facility and technical limitations also come into play. The Chaska Sub is a facility owned by Chaska Public Utilities, also offers limited space rented for MVEC's use. The new proposed installation will provide considerably more system growth potential, improve MVEC system reliability and also provide some backup capabilities to both the Bluff Creek and Chaska Substations under emergency conditions. 1~ A major benefit ofthis site is that existing Xcel Energy 115KV transmission line crosses the property and eliminates the need to extend new transmission lines to the site. MVEC is working jointly with Great River Energy (GRE) and Xcel Energy to tap into this location. The presence of existing MVEC distribution feeder lines also contributes to economical construction, maintenance, and lower costs. to electric customers. Additional underground distribution feeder lines will need to be installed to tie into other parts of the system. The proposed location provides adequate system capacity for the foreseeable future, and enhances system reliability for the area. MVEC is pursuing a Conditional Use Permit (CUP) for a Public Utility Structure as an essential service permitted by Article IV, Conditional Uses within standards set forth within Division 4, Section 20.313 with some special consideration.. The facility proposed would be a modern design, low profile Distribution substation with a modular switching unit surrounded by a 10 foot pillar and walled concrete fence enclosure on three sides replacing the standard 8 foot high chain link fence and barbed wire enclosure that is typical for this type of facility. The enclosure measures 160 X 185. The remaining code required fencing will be 8 feet high for safety and security, and access gates will be locked at all times or under the direct supervision of authorized personnel. MVEC proposes additional conifers and shrubs strategically placed on the perimeter of the property to break up and screen the site per the plan. All new vegetation will be warranted for at least two years. Naturally existing trees and dense vegetation exist along the east side of the property will remain to screen to the east side. Exit corridors for both overhead and underground electrical feeders will be required to remain clear of tall screening to assure system reliability. MVEC will install and maintain screening in the form of shrubbery to the extent that they will not interfere with the reliability of the substation operation. The substation will be maintained in a neat and orderly fashion. Storm water drainage will be controlled on site to meet or exceed the City and watershed requirements. The fenced in area will be maintained as a gravel surface. The driveway and parking area will be blacktopped. Field inspection and available records indicate significant wetlands will not be disturbed. MVEC is providing the new substation site plan as part of the application. A purchase option with M. A. Gedney, Inc. provides property interest to MVEC. MVEC is making application to the Watershed District to review the specific conditions of the Conditional Use Permit. Signage will be limited to an identification sign on the fence of the substation, and warning signs to the public as required by the current National Electrical Safety Code. Within the fenced in area, a minimal quantity of transformers may be stored to accommodate the prompt response to local outage situations. , 7c. Additional information: The proposed substation will reduce the electric transmission line voltage from 115 KV down to 12.47 KV for distribution to the local service area. A Local Distribution Substation of this variety will contain transformation, regulation, metering and switching capabilities. A modular, self contained control unit will be incorporated within the fenced in area to monitor and regulate the functions ofthe facility. Many functions are monitored remotely and access is most prevalent to respond to outage conditions or to maintain the grounds. Most access is during daylight hours however 24/7 access is required. Site visits typically are only for duration of a few minutes. Once constructed, trips generated per day will vary but typically would average only a few trips per week. Vehicles accessing the facility typically are pickup type trucks or utility bucket truck type vehicles and not normally more than two at a time. Short term parking will be provided which will accommodate parking for up to 4 utility vehicles in front of the fence. Some units may occasionally pull trailers. No water or sewer will be utilized as part ofthe operations of the electrical substation. The substation design will comply with the State Building and Fire Code. In addition, the design will comply with the current National Electrical Safety Code. MVEC's application includes provisions for variances and subdivision as noted. This project enhances the electrical distribution system capabilities and reliability for the customers in the immediate area. MVEC would intend to start construction as soon as possible with the facility placed in service in late spring of2006.

Electrical distribution and undereround electric distribution substations. Electrical distribution and underground electric distribution substations are subject to the following conditions: (1) The distribution and underground electric distribution substations must be served by a collector or major arterial street as designated in the comprehensive plan. · The site is served by Stoughton Avenue. The current street provides access to the Gedney plant as well as other industrial facilities within the general area. (2) The distribution and underground electric distribution substations will not have sanitary facilities and will not be used for habitation. · MVEC's on site operations short term require no habitation or extended presence and has no need for sewer. (3) The distribution and underground electric distribution substations will be located on at least five acres of property. . Actual area within the fenced premises is less than 3/4 acre. An over all area of 2.5 acres generously provides setbacks, parking and any landscaping. Highest and best use of the property would not support the need for additional property for this facility which would remain underutilized. (4) A security fence as specified in the National Electric Safety Code shall surround the distribution and underground electric distribution substations. · Normally an 8 foot chain link fence with two strands of barbed wire would be utilized for the entire enclosure. MVEC proposes alO foot modular concrete wall type enclosure for the most visible areas as noted on the plans with the standard chain link fencing for the remainder as noted on the plan. (5) A landscaping plan shall be submitted for city approval. . Due to the addition of walled screening, landscaping is confined to the parking areas, the remainder of the chain link portions and strategically located along walled sections.. (6) Distribution and underground electric distribution substations shall be a minimum of500 feet from single-family residences. · The facility is positioned approximately 400 feet away from the closest mobile homes however the existing Xcel switch station is located closer and across the street from the same homes and existing transmission lines cross above those homes. These homes would experience no increased impact from the proposed substation facility. (7) A summary of current research regarding the health effects of EMF levels, conducted by health and scientific professionals, including those who do and do not receive utility sponsorship. . A study by The National Institute of Environmental Health Sciences, The Environmental Protection Agency (EP A) and the US Department of Labor Occupational Safety and Health Administration has been provided along with references to various other web sites. In summary, EMF levels generated within ~6 the substation facility are projected to be reduced to near normal background levels at the fence perimeter (8) Provide EMF levels under maximum and average anticipated loading at the base of the utility poles, underneath the wires between the poles, at ground level above underground wires, at the edge of the property line, at the edge of the closest habitable building, and at the point above ground where there would be the greatest EMF level. . See diagram provided. (9) Reasonable and prudent measures to minimize EMF levels along all alternative electric line routes. . Per EMF-Rapid study, the EMF levels within a substation drop off dramatically as distance from equipment is increased. At the substation fence, EMF levels are indistinguishable from background levels. MVEC has verified this to be true by taking our own measurements. Distribution voltage lines, both overhead and underground, have very low EMF levels and also are indistinguishable from background levels at a short distance. (10) Depictions of the views of the proposed facility, if above ground, from at least two directions selected by city staff. . Please reference plan views provided. (11) The site is guided office/industrial on the City ofChanhassen Land Use Plan. . The "Gedney" site is so designated per staff and the current zoning map.
