Planning Office, Bill Kane RE: Site 4, City Electric Building DATE: January 23, 1978 The City's search for a site for a new electric switch gear building commenced roughly in the fall of 1976. In February of 1977, detailed plans for a City electric switch gear building were proposed to the Board of Adjustment for a location at Cemetery Lane and Highway 82. As you may know, it is necessary to locate this facility in a reasonable proximity to a feeder line which will come from the Colorado Ute Sub- station at the Airport Business Center to the City of Aspen to provide addi ti ona 1 switching ci rcui ts to take) full advantage of the hundred and fifteen (115 kv) increase into the valley. A variety of locations were studied in the fall of 1976 with a decision being made for the location of Cemetery Lane in January of 1977. The Board of Adjustment found that they could not provide a variance to allow the building to be constructed in that location and staff was directed to consider alter- native locations. Subsequent to that exercise, additional planning has been conducted by Holy Cross who will construct the feeder line with the County Planning and Zoning Commission and County Commissioners. The up shot of this process was to locate the feeder line in the Rio Grande right of way which will provide power .' into the City along the old railroad right of way will come into the City roughly along the alignment of Lot 3 of the Trueman Subdivision. Subsequent to the turn down on the Cemetery Lane locati on, four additi ona 1 sites in that location were considered. One invol ved.a site on City property further down the bank towards Castle Creek. The second was on the City's Shop property and two sites were considered on. the south side of the Hi.ghway 82 bridge along Castle Creek including a site on land owned by Opal Marolt. For both financial and engineering reasons, sites in the area of Castle Creek were eventually abandoned. With the final decision having been made for the alignment of the feeder line to use the Rio Grande right of way, is incumbent upon the City of Aspen Electric Department to find the site in a reasonable proximity to the terminus of that line which again is Lot 3 of the Trueman Subdivision. In looking at this area of town, 12 sites have been investigated to varying degrees of detail. I would like to briefly discuss each of these with you at Monday night's meeting and will hopefully pursuade you, as we have been, that the Craig site on Puppy Smith Street within the Lakeview Subdivision appears most appropriate and cost effective at this point. Site One - Pitkin County No. 2 -- This area is located between the hospital and Silver King apartments and is that broad open lot that leads to the trail head to Hunter Creek; This site, from an engineering standpoint would be expensive to construct because it would require river crossings and extensive heavy construction to embed the line across the riverbed to get to this site. In addition, Pitkin County has considered, on several occasions, the possibility of using this landfor additional housing in the area under some form of public sponsorship. Construction would be expensive and the location of even this 900 square foot building would preclude potentially much higher uses for the site. In short, this would be a . squanderi ng of val uab Ie ground. . ~ ~ , . Aspen City Council Page.. Two January 23, 1978 Site Two - City Storm Ponds -- The engineers have rejected thi S a lternati ve due to its proximity to the Roaring Fork River and seasonally high water in. the area which wOuld present serious maintenance problems to the delicate nature of the electrical equipment envisioned here. . Site Three - This is a site study area within'the Aspen Sanitation District property. Specifically, the site being considered is on the north side of the existing plant and is in immediate proximity to the flood plain of the river and again is a low piece of property with seasonally high water and is not acceptable from an engineering standpoint. Site Four - Pitkin County No. 1 -- This is a tract of ground immediately north of Mill Street and the proximity of the river. It is covered by a 1 Birge grove of trees and in order to minimize disruption and cutting in the area a site has been identified on the north side of this tract of ground and the objections from the engineers here are the same; that while it may technically be outside the flood plain, the site is extremely low and is subject to flooding and seasonally high Water. , Site Five - Holy Cross Property -~ This site may well stand within the 100 year flood plain due to the channel alter- ations that have taken place in thi s part of the City. From a planning standpoint it is highly questionable as to the wisdom of constructing a building of this nature; immediate proximity to the Holy Cross Building for which $300,000 has been budgeted for purposes of renovation of the building for a visual arts center. We have worked long and hard for removing the e.lectric utility function from this site to be supplanted by an art aesthetic function and a decision to locate an electric building on this site would be difficult to justify from a planning standpoint. Sites Six and Seven are Andrews and Cap's respectively. Both of these consist of existing buildings and both present engine- ering and planning problems. From the engineering standpoint, both buildings would have to be so thoroughly renovated to accommodate the electrical gear that any building on these sites would have to include complete removal and replacement of the buildings. In both cases, tremendous costs would be involved. Mr. Andrews presented to us last year, and as of a year ago, has paid over $400,000 for both buildings and land in the location of the Andrews' site. We have not completed an appraisal nor do we know what Cap's would want for their property; but you can well imagine that it would be an expensive property to acquire and it should be balanced against the needs sought. Site Nine - The Aspen One Property -- As you know, from the staff level we have made repeated attempts to discuss planning on this property with the owner and have recommended that the City acquire this land for purposes of restoring the original channel of the river and locating the Roaring Fork Greenway, a pedestrian-oriented highly landscaped river front park. Needless.to say, an electric building would be totally con- trary to the goals as they are established in the adopted S.P.A. plan for the Rio Grande property. ,-., .~ Aspen City Council Page Three January 23, 1978 Site Ten - Land north of the Obermeyer Building within City ownership along Spring Street. WhHe this site would be expensive from the standpoint of,engineering, in that itwou]d ,r,). require extension of the feeder line for an additional two thousand to twenty-five hundred feet; it is one that could feasibly be developed from a planning point of view. However,.,' it would seem an unfortunate decision from the standpoint of setting a circulation pattern and land use pattern on a two million dollar piece of property to satisfy the needs of one 900 square foot building. Site Eleven - Baker site -- which is land zoned R-6 within Lakeview Subdivision in an immediate proximity to the Trueman Lot 3 and the alignment of the feeder line. Though we have found this site to be initially acceptable and we are pursuing the idea of acquiring this for purposes of the building; several complications have arisen with respect to this site. First of all , the site is small and is going to create space problems regardless of various City required Board of Adjustment processes! So there is some question about the utility of the site from an engineering standpoint. Secondly, there are numerous variances that wi 11 be required by the bui 1 ding and this will require a fairly lengthy review by both the Board of Adjustment and the Planning and Zoning Commission. Complaint has already been received by the immediately adjacent neighbors and it looks like ,to feasibly develop this site, would require the acquisition of the entire Baker. property to include the Caparella house to the immediate west. This would result in a land cost of $150,000 for this facility. Site Twelve - Our recommended, site is the Craig property which is south of Puppy Smith Street and immeidately behind Lot 2 of the future site for the Post Office behind the Rio Grande property. The plan consists of almost 15,000 square feet. It would be an adequate area to carefully design the building and screen it, landscape it so that it could be bought off in a totally compatible residential design leaving a,large balance of the tract and open spa.ce. Cost for this land would be $119,000. Of the sites investigated, we feel this would be superior due to: l) engineering costs and ease of construction; 2) size and location of land from a land use planning standpoint; 3) the time'consuming City reviews that would be required with each of the alternative sites. From the point of view of all three of these, the Craig site is clearly superior. Conclusion The decision for the location of the switch gear building is becoming critical. Feeder line construction will be completed in the summer of 1978. This building is the critical completing link to the overall distribution network for the City of Aspen which will be necessary to take advantage of the 115 kv line which is nearing completion now. We will appear at Monday night's meeting, have the engineers available to discuss each of these sites, solicite any comments from the Council and hopefully receive your approval for the purchase of the Craig site with authorization to proceed. ,."..., ~ (.C, -G. C'i"\ MEMORANDUM TO: Aspen Planning and Zoning Commission FROM: Planning Office (BK) DATE: February 16, 1978 RE: Conditional Use Hearing for the City of Aspen Electric Building At Tuesday's meeting, you will be presented with an appli- cation for conditional use approval for the location of a 1,500 square foot City of Aspen electrical switch gear building on the craig property within the Lakeview Subdivision. As you will recall, at your meeting of December 20, 1977, the Board voted to find that the electric building envisioned would qualify as a public administration building and, therefore, is eligible for consideration under the conditional use list of the R-6 and R-15 zones. In granting conditional use approval, the code envisions that you consider the impacts of this specific and unique use on the general character of the surrounding area. In conducting such an investigation, certain pertinent facts are in order. First of all, the Planning Office has supported this site principally by virtue of the changing character of land use in the area, and the site's immediate proximity to the feeder line which will provide service to the City along the Rio Grande right-of-way or Lot 3 of the Trueman Subdivision. This site consists of some 15,000 square feet and is the first residential property on Puppy Smith Street as one enters the Lakeview Subdivision. This building will be immediately adjacent behind, and for all practical purposes, totally screened by the post office building on Lot 2 of the Trueman Subdivision. The balance of this area is zoned R-15 and is residential in character with several old miner's cabins fixed up and currently lived in.llith the development of Puppy Smith Street, the eventual development of Lot 3 of the Trueman Subdivision, the construction of the Aspen Venture Building, the post office and the Trueman Building, it is rather obvious that the character of this area is undergoing transition. In fact in our previous proposal some years ago to rezone this area to R-30 to preserve it as extremely low residential density, the Council indicated an interest in preserving this area at R-6 and even considering rezoning it to RMF as a site for potential lower cost or employee housing. In considering the electric building, certain things should be borne in mind. In our various considerations, we have encouraged the applicants to design a building that would be in fitting with a residential scale and, therefore, should use soft materials such as wood exterior, adequate landscaping, reasonable height limitations, set backs, etc. Greg Cole has prepared several drawings of a building that is very similar in design to the Park Maintenance Building in that it involves earth berms and a building that is low with fairly simple lines. From a design standpoint, the building appears to be quite compatible with the area now and compatible with anything that may develop in that area. From an activity standpoint, the majority of this 1,500 square feet will be occupied by about six to seven hundred square feet of switch gears space, six hundred square feet of parking space for two vehicles, and the balance will be for meter storage and a small desk. I think from the plans shown the activity that will take place on the site will also be consistent with the character of the area. Mike Jones of Merrick & Co., consultants to the City of Aspen Electric Department, will be present at your meeting on ~ ~" ,-, .r,J:,. (,?,) Tuesday to present these plans and take comments from.the Board and request will be made for conditional use approval. As you may have gathered from recent reports on the radio and in the newspaper, in conveying this land to the previous owner, Mrs. Paepcke had placed a restrictive covenant on the site restricting it to residential use only. This problem is being attended to by the City Attorney and Manager, and we have indication that this restriction will be released. At any rate, such covenant is not pertinent to the deliberations before the Board. You will be required simply to look at the building and make a determination as to whether it fits the surrounding area and whether the activities envisioned are compatible with the surrounding area. Given the information to date, we find the design and proposed use to be compatible and at Tuesday's meeting will recommend approval of this project. BK:mc ,-., ..,......." ~ ~,.

This facility as proposed to be located in the Lakeview Subdivision immediately adjacent to Lot 3 of the Trueman Subdivision. The land in question is at the "Y" that is created by Puppy Smith's Street as it continues through Lakeview Subdivision and the turn to the right formed by the old D&RGW Ra il road ri ght of way. The City has been trying for some 18 months to find an adequate location for a facility to house approximately 900 square feet of equipment and immediate work space. As you may recall, a request was made before the Aspen Board of Adjustment sometime ago to locate this facility on City owned land at the intersection of Cemetery Lane and Highway 82. While there is a broad exemption within Section 24-2.7 of the Municipal Code which provides an exemption from zoning "utilities" and "essential services" the Board, at that time, found that the accessory parking and small office space that was proposed in the building at that time was not something covered by the exemption and therefore it was denied. The building and application has been modified in several ways. The previous site was located in the "Park" zone which does not provide for public administration buildings. Now the R-15 and R-6 zones does, as a conditional use. The amount of space accessory to the swith gear has been substan- tially reduced and now consists only of a small room to store electric meters and additional room with a table to provide space for maintenance logs for the faci 1 ity. We propose thi s appl i cati on be brought to you in two steps: 1) at Tuesday's meeting, you are being requested to find that this facility is intended,to be covered by the conditional use specification within the R-15 zone; and having accomplished that then you will be presented with detailed building plans in fulfillment of the requirements of the conditional use hearing at your meeting on January 3. We will have conceptual drawings and indication of the building available for your inspection, at your meeting on the 20th; and we will supply a greater detail for the January 3rd meeting and will solicite any comments or additional recommendations that you may have at that time. The construction of this building is critical to the electrical needs of the City of Aspen. It should not be looked upon as a frivolous building that could be located ina variety of other locations. But the plai~n 'fact of the matter is the City is coming down to the wire on finding a location for this equipment. As you may recall, Colorado Ute is about to complete the construction of a new 115 kv line in the Roaring Fork Valley to supply additional power to Aspen, which for the past two winters, has faced the immediate prospect of blackout and we were saved from that fate by having low energy demand during the winter season. We believe that a fair and adequate consideration has been given to alternative sites to include: land at the golf course, land at the intersection of Cemetery Lane and Highway 82, of City Shops below the Castle Creek Bridge, City Water Plant sHe, Rio Grande property, Lot 3 of the Trueman Subdivisi6n and now this site. From a cost standpoint and from a land use standpoint, it makes more sense to locate this thing adjacent to the ""'" ~. Aspen Planning and Zoning Commission Page Two December 16, 1977 Rio Grande right of way. Plans now call for the construction of an underground power line to come from the Colorado Ute Substation behind the Airport Business Center down the bank to the Roaring Fork River and into the City along the Rio Grande trail. We feel that this is a far more environmentally suitable solution than the originally proposed overhead strung wires to come in along Highway 82. In order to take advantage of thi s locati on, the switch gear whi ch wi 11 be necessary to provide power to the City from this new line will be required to be constructed in some reasonable proximity to the Rio Grande trail. Our most recent attempt, we approached Jim Trueman with the idea of purchas- ing Lot 3 of the TrUeman subdivision and found upon the appraisal of some $400,000 that we are incapable of spending that much for such a limited facility. We feel that through adequate design, landscaping and site orientation, this location will be quite suitable for the facility with minimal or no impact to the neighborhood. After a consideration of the application, and one-and-a-half-years of trying to find alternative sites for this facility, we recommend that you find the proposed switch gear site to be within the definition of a public administration building as listed within the range of condi- tional uses within the R-15 zoning district, You should also recognize that by taking such action, this does not open up the spector of having additional public administration buildings throughout the zone of similar nature but only finds that in this instant case that the facility proposed is appropriate for the site in questi on. Dave Ell is wi II appear at the meeting on Tuesday to answer any additional questions that you might have. Imk
