Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 2. Public Hearinq--Consideration of a conditional use permit which would allow a public utility building in a PZM zone. (J.O.) A. REFERENCE AND BACKGROUND: As you know, the City Council recently adopted the ordinance amendment eliminating public works facility as a permitted use in the PZM zone and adopted the ordinance amendment making a public utility building a conditional use In the PZM zone. Planning Commission and City Council are now asked to review the public works department expansion plans and consider granting a conditional use permit which would allow the development of the site as proposed. Following is a general description of the adjoining area, a review of the site plan in terms of adherence to the city ordinance, followed by alternatives and a staff recommendation. General Area Description To the north and east of the property lies the Burlington Northern railroad right-of-way. This right-of-way is 100 feet wide. On the opposing side of the right-of-way there is dense foliage that screens an undeveloped portion of school property. The presence of the public utility building appears to have no impact on this area. The potential impact is minimal because the land is owned by the school and is likely preserved as open space by the school. The dense foliage does not run the full length of that side of the property, which results in the Pinewood playground and elementary school having a clear view of the existing pole building located at the northern most extreme of the property. According to the proposed site plan, the pole building will be screened by pine trees planted in conjunction with site development. This tree planting will also screen the view of outside storage from the school property. To the south of the site is County Road 39. Across 39 are five properties. Farthest to the east and across from the undeveloped section of the public works site are two residences. Directly across from the eastorn-most entrance to the public works facility is the Griofnow Shootmetal business, along with a home owned by Mr. Griefnow. The majority of the property directly across from the public works facility is vacant and undeveloped. This undeveloped area is bordered on the south side by Ruff Auto. Property farthest to the south and east of the site is owned by Bridge Water Telephone. This site is used for outside and inside storage of telephone company equipment and materials. To the west of the property is the West Cello apartment complex. The West Cello apartment complex is configured so that the majority of the general parking and drive area is directly adjacent to the public works site. There is an existing apartment on the northeast corner of the West Cello site that is directly adjacent to the existing pole building. The majority of the public works site, however, is bounded by the West Collo general parking and drive area. Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 Site Plan Description Buildinq. The proposed site plan calls for development of a 15,000 sq ft building with phase I construction. The main purpose of the maintenance building is for storage of city vehicles. In addition to storage of vehicles, vehicle maintenance and sign shop activities will occur in the proposed maintenance building. The increase in storage area provided by the maintenance building will allow the City to store materials inside that were once stored outside. The structure is located on the site in a manner that will allow the City to take advantage of the presence of the existing maintenance shop and existing water department offices and building. Future phases will connect the structures so that they are integrated into one functional complex. The setbacks with phase I meet all City requirements. The shortest setback on the west side amounts to 28 ft, which is well within the minimums. Fuel Dispenser. The site plan calls for placement of the fuel dispenser on a concrete slab approximately 28 ft from the boundary of the west Cello apartments. The fuel dispenser has met all the requirements of the fire marshall and pollution control agency. The fuel tank is placed on the west side of the property because the impact of fuel dispensing on the adjoining property can be minimized through installation of a screening fence or landscape planting. In addition, the proposed location of the fuel tanks will allow for adequate security of the fuel dispensing area and will result in optimum traffic flow. Site Traffic Circulation. City vehicles operated out of this site will generally enter the property from the west side and fuel up prior to entering the building so that they will be ready for use on a moment's notice. The fueling activity will occur for the most part between 3 p.m. and 4:30 p.m. during the working day. It is not likely that considerable fueling activity will occur during early morning hours. Vehicles exiting the building will exit on the east side of the property and cross over a gravel surface area prior to reaching the county road. Normally, this drive area would need to be paved; however, phase II construction would likely result in the need to remove a portion of the paved surface. Therefore, a variance is requested which would allow the paving of this area to occur after development of phase II. Employee Parking. At the present time, there is sufficient parking space to allow for one vehicle for each employee and up to six additional vehicles. The city ordinance does not outline any specific parking requirement for a public utility building; therefore, given the available space as described above, the plan meets the spirit of the zoning ordinance. It should be noted that future phasing will Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 result in displacement of some of the parking spaces. This may require that employee parking be developed at another location on the site. In addition, the existing parking area does not possess curb and gutter. The present drainage system works fine with water from the parking lot shedding directly to the county ditch. From a storm water management standpoint, there is no need at this time to install curb and gutter. Technically, however, this is an aspect of the site that is not in conformance with city ordinance. A variance will need Lu be granted that would allow intensification of the use of the site without development of a curb along the boundary of the parking area. All areas paved as part of the proposed project will be bounded by a curb system except where a paved area transitions to a gravel surface. Tree Requirement. The tree requirement for this site is 38 trees. After reviewing the site, I found that there currently are more than 37 trees on the site; however, some of the trees do not meet the minimum in terms of size. In those instances, I counted one tree for every two trees that are undersized. After the adjustments were made for the smaller trees, the total number of trees amounted to 37. The total trees counted does not include any trees that would be planted as part of an effort to screen the facility from the neighboring apartment units. The development, therefore, appears to meet the tree planting requirement. Landscape Screening. The site plan calls for a double row of 6 -ft to 8 -ft pine plantings running nearly the full length of the northwest side of the property and running approximately 100 ft along the northeast side of the property as noted on the site plan. Trees will be planted in a staggered fashion with a 10 -ft separation. This method of screening will result in a screen that is nearly 1001 opaque. An irrigation system will also be Installed to assure the health of the evergreen plantings. At this time, additional screening has not been proposed; however, Planning Commission and Council may wish to consider a similar planting in strategic areas along the southern boundary of the property. This would shield some outside storage from the County Road 39 right-of-way and shield some of the outside storage from the view of the three homes across from the facility. In addition to the landscape planting, there will be slate placed In the cyclone security fence protecting the fuel dispensing area; and slate will be placed in the fence surrounding the storage area at the rear of the phase I structure. These slats will serve to provide additional screening of fueling and storage areas from the view of the county rund right. -of -way and from the view of Lhe schoul property. Gravel Storaqo Area, Gravel Surface. As you will see on the site plan, there is a relatively largo area directly oast of the maintenance building that is needed for storage of various items used by the public works department and by citizens of the community. The City presently provides wood chips and compost material to citizens Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 free of charge. This type of material could be stored at this site in bins that would be screened by landscape plantings. The openings to the bins would be placed strategically so that actual materials stored could not be viewed from the right-of-way. Security. At least three security lights will be installed either along the building or on poles along the western edge of the property. Security lights will illuminate the fuel dispensing area and the fence that will extend the length of the western side of the property. This security fence will also extend along the northeast side of the property to a point even with the eastern wall of the maintenance building where it will be connected to the building. Installation of this fenced area will create a secure environment for any short-term outside storage of materials, which will result in lees vandalism and theft from the site. The security fence system will also include a sliding gate at the entrance to the fuel dispensing area. Drainaqe. The City Engineer is preparing a plan for management of the storm water that will be produced by the site. According to the City Engineer, it is feasible to convey the water from the site to an existing city storm water system without the water being deposited onto private property. Additional information regarding the storm water plan will be provided by the City Engineer. Review of Ordinance Requirements Following is a review of the site plan in terms of the requirements set forth by the city ordinance. In order for the conditional use permit to be granted, the site needs to meet the requirements as set forth in the ordinance amendment adopted by the City Council at the previous Council meeting. Following is a review of each of the conditions noted by ordinance: 1. Conformity with the surrounding neighborhood is maintained and required setbacks and side yard requirements are met. The proposed use of this property as a public utility building Is in conformance with the city ordinance, which allows public utility buildings to exist in the PZM zone. The neighborhood in which this public utility building is proposed conforms with the proposed use. Directly to the south of the site is a storage facility used by Bridge Water Telephone and a vacant undeveloped property that directly abuts Ruff Auto. Also along the south side of the property is Griefnow Sheetmetal. The neighborhood also Includes throe homes along the eastern tip of the property. These homes are located some distance from the maintenance building and are located directly across from that portion of the site currently planted with trees that will not be actually used by the public works department. Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 To the north and east of the site are railroad tracks, dense foliage, and vacant school property. The public works site development will not have an Impact on this portion of the neighborhood. To the west of the site is the West Cello apartment complex. The ordinance states that conformity with the surrounding neighborhood is maintained. Conformity will not only be maintained but will be improved through installation of a landscape screening as described earlier. Given the types of uses adjoining the property and the landscape screening proposed, it appears that the proposed site plan will meet the requirement that the site be in conformance with the surrounding neighborhood. The ordinance also requires that adequate screening from neighboring uses and landscaping are provided in accordance with Chapter 3, Section 2, of this ordinance. As noted earlier, opaque screen will be provided that will mitigate any negative impact on the apartment complex. Planning Commission and Council may wish to consider additional landscape plantings in strategic locations along the southern boundary of the site if it wishes to improve screening of the site. The key word in the ordinance is "adequate screening." Planning Commission and Council need to determine if adequate screening is proposed within the site plan. If Planning Commission and Council believe that property values can be better protected by planting additional trees, then this option should be considered. Item 04 of the ordinance states that the facility must have direct access to a county or city/state aid highway. The site plan meets this requirement. Item 43 of the ordinance states that the provisions of Chapter 22 of this ordinance are considered and satisfactorily met. With any conditional use permit and any zoning ordinance amendment, Planning Commission and City Council must consider whether or not the proposal is consistent with the comprehensive plan; is It consistent with the character and geography of the area; will the conditional use tend to depreciate the area; and has the need for the conditional use been demonstrated. The factual answers to these questions then become the basis for your decision. Following is a rovic,4 of the site In terms of each of the criteria that should be reviewed when addressing a conditional use permit application: Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 Consistency with comprehensive plan. Enclosed you will find two excerpts from the City's comprehensive plan that appear to address development of public utility facilities. As you will note, the comprehensive plan states that facilities should be constructed and developed to generally accepted standards. The proposed site plan, building design, and landscaping plan meet this requirement. In addition, the comprehensive plan describes the public utility building in detail, and nowhere in the comprehensive plan does it state that the City should consider moving the facility. B. The Geographical Area Involved. The proposed site is located relatively close to the center of the community, which provides for efficient operation of public utility services. By locating the structure relatively close to the center of the community, maintenance operation travel time is minimized. In terms of the benefit to the entire community, the proposed location of this facility makes sense. C. The Character of the Surrounding Area. As noted earlier, the proposed facility is consistent with the character of the area and the PZM zone. Even though the site is centrally located in the community, it is buffered well on the northeast side by the railroad tracks and school property. To the south side, the site is buffered by a major county road; and to the west, the site can be buffered by the planting of a double row of evergreen trees. The site IS configured so that the majority of activity that would occur on the site would occur in areas away from the adjoining parking lot and apartment buildings associated with the West Cello complex. Some of the adjoining uses to the south include land uses somewhat Similar to the proposed utility building. These would include Bridge Water Telephone, Ruff Auto, and Griefnow Sheetmetal. After taking a look at the character of the overall neighborhood, it would appear that an Improved public utility facility would be consistent with the character of the surrounding area. Whether Such Use Will Tend to or Actually Depreciate the Areas in Which it is Proposed. It is difficult to imagine how improving the site as proposed will result in a depreciation of any adjoining land values. The site as it currently exists is devoid of any type of screening whatsoever. Unscreoned storage of materials is currently necessary because there is not enough room In the existing structures. The removal of the old shoetmetal storage building and replacement with the utility building, along Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 with the landscape plantings, paved areas, and security fencing, should not result in a depreciation of adjoining land values. E. The Demonstrated Need for Such Use. The City simply needs to have enough room to store vehicles and materials inside. The proposed utility building is in a response to that need. It is, therefore, self evident that there is a demonstrated need for this use. 8. ALTERNATIVE ACTIONS: 1. Motion to approve the conditional use permit based on the following findings: 1. The proposed conditional use permit is consistent with the purpose of the PZM district, which is to provide a land use transition between high density residential land uses and low intensity business land uses. The public utility building site plan, which includes extensive screening, landscaping, direct access to county and city state aid highways, and separation from R-1 and R-2 uses, is found to be consistent with the stated purpose of the PZM zone. 2. The present mix of uses in the PZM district at this location is compatible with the proposed conditional use, and the proposed conditional use is consistent with the geography and character of the area. 3. The proposed site is sufficiently separate from single family residential areas and is centrally located so as to provide ease of access to all areas of the city which will be serviced by the facility. 4. The conditional use proposed will not depreciate the area in which it is proposed, as it will be an improvement to what was once a permitted use, will enable the City to store vehicles which would otherwise remain outside, and will be aesthetically pleasing. 5. The use of the present site has grown so as to render the existing buildings inadequate for the stated purposes and, therefore, requires expansion. The need for a public works building in the city the size of Monticello Is obvious. 6. The proposed conditional use is consistent with the comprehensive plan. 7. The proposed site moots the requirements as outlined by city ordinance. 7 Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 Under this alternative, Planning Commission and City Council are comfortable with allowing expansion of the public utility building to occur at this site based on the findings as noted above. It should be noted that the technical requirement of the ordinance requires that the City Council review conditional use permit applications at their reqular meetinq after the Planninq Commission meeting. Since this is a special meeting, there is some concern that anyone opposing the facility would say the City is violating the formal process. Paul Weingarden is researching this matter. It is his view that this provision is written to eliminate any stalling that could occur after the Planning Commission renders a decision. At this point, he does not think it would be inappropriate to have Council consider the matter at a special meeting. At the same time, however, he doesn't want to provide an opportunity for the project being halted due to an "irregularity" in the process. An update regarding this will be forthcoming. Worst case is the item will be placed on the June 22 agenda. Motion to deny the conditional use permit allowing expansion of a public utility building. Under this alternative, Planning Commission and Council are not convinced that the facts clearly demonstrate a finding that supports Issuance of the conditional use permit. C. STAFF RECOMMENDATION: It is the view of City staff that the proposed conditional use permit meets the standards as outlined by the conditional use permit critoria. It is our view that the findings support a decision to approve the conditional use permit. D. SUPPORTING DATA: Copy of the site plan; Copy of the excerpts from the comprehensive plan; Copy of 7/8/91 Council minutes; Copy of 9/23/91 Council minutes; Copy of storm water run-off evaluation from City Engineer. ••NOTE: Due to Jeff's absence today (Friday), I thought I should type a short note to lot you know that Paul Woingarden reviewed the ordinance and called today to recommend that Council wait until the next regular Council meeting to consider the conditional use permit. Karen Doty Office Manager COMMUNITY FACILITIES POLICY 1. Presently, the development of land for public facilities such as parks and playgrounds is considered more important than the acquisition of such land. However, with respect to acquisition, land must be purchased before proper sites are usurped by private developments or high land prices make acquisition unfeasible. It is a desirable goal of the City to balance -7-acquisition and development efforts. \ All public facilities are to be developed according to generally accepted standards and the results of thorough study. 3. where feasible, private aevelopers will be required to set aside a portion of their land for public use= where this is not feasible or desirable, developers will be required to contribute cash in lieu of land, with such money to be utilized for the purchase and development of recreational facilities. 0. School facilities should be fully utilized by making building and land available to the public for use when such does not conflict with normal function of the school facilities. 5. Private developers will not be required to donate land for school sites. 6. Churches should have an ample site for building, landscaping, potential expansion, and off-street parking. Parking should be provided on the maximum design capacity. Churches should be located adjacent to a thoroughfare or collector street and have easy access to the area served. They shculd not be located on minor residential streets and in the midst of residential neighborhooda. 7. The City should not accept substandard lands such as swamps, power line easements, etc., for the development of park lands. This shall include lands laid out in subdivision plane. Open Space Policies Before delineating open apace policies, a definition of the term is necessary. Traditionally, open space hes been primarily defined as that area which is retained in or restored to a condition where natural systema predominate and which may be used for recreation, or preservation purposes. Open apace woo often regarded as a separate and contained entity usually under the ovnerahip of a governmental jurisdiction. Recant trends indicate that open apace, like the people it serves, is becoming more directly integrated with its surroundings. Becoming more a part of the total urban fabric, open apace is being more closely Integrated into the urban living and working environment. Because of this integrating phenomenon, many of the advantaged and recponnibilitiea of open apace are equally applicable to public and private lands. 1. Public Services Sanitary Sewer Service: The Wastewater Treatment facility for the City of Monticello is located in the northeast part of the City between County Road 75 and the Mississippi River. The Treatment facility waa recently upgraded with conatruction being completed in 1984 at a coat of well over $5 million. The facility is an activated sludge plant designed to handle wastewater from residential, commercial, and industrial properties within the City of Monticello to a population of 6,400 people in the year 2000. The average daily design loads for the wastewater Treatment Plant are as follows: 910,000 gallons per day for flow, 6,271 pounda per day for BODS, and 1,224 pounds of total ouapended oolido per day. i' -19- Municipal Off -Sale Liquor Store: Located on Pine Street (just west of the railroad tracks), the Municipal Liquor Store was constructed in 1976 and includes approximately 6,400 square feet of floor area. Monticello Senior Citizens Center: This facility was acquired in August of 1977 at a cost of $44,665.00. This structure was acquired with reserve funds and did not require bonding. In addition to housing the Senior Citizens Center, a portion of the facility was rented to a private printing firm until 1982. The center was expanded in 1982 to incorporate that area which had been rented. Perhaps the most active 'small town' center of its type in Minnesota, the center is open seven days a week with activities including cards, crafts, ceramics, woodworking, pool table, planned trips, monthly birthday dinners, fish frys, free blood pressure checks, and other activities. Public Works Building: The Public Works complex is located Qn tv ^ n on West County Road 39 near the Pinewood Elementary School. The buildings. One yr E N complex consists of three of larger QQ the buildings of masonry construction serves as a central shop for the Public Works Department. Another nearby metal construction type building serves as cold O storage and offices for the Public works Director and MOJQ Street Superintendent. The third building at the site is 0 of metal construction with half of the building being for cold storage, the other half being heated storage. JThe majority of the Public Works equipment is kept at this complex. This equipment includes the necessary lawn mowers and tractors, rubber tired wheeled loaders, anowblowers, four dump trucks with snowplows, two of which have wings and sanders, pickup trucks, the City's motor grader, and other miscellaneous equipment related to Public Works activities. 1.

John Simola reported that over the past several months City staff has been preparing site plans outlining options for development of the public works facility located on Golf Course Road. Footprint drawings have been prepared of the existing buildings, and staff has looked at space requirements of existing equipment as well as future needs. In addition, the public works department has looked into the possibility of adding on to the existing masonry public works building along with various combinations of removing the old pole building or letting it remain. There appear to be a great number of options in regard to building additions, none of which appear to solve all of our needs. Simola went on to suggest that the City Council enlist the assistance of the engineering firm, TKDA, to assist in selecting a cost-efficient alternative that would address all of the work study issues. TKDA would also prepare conceptual site and floor plans for an option to be selected by City staff and Council. Simola noted that TKDA has given us an attractive lump sum price of $2,750 for the study with an estimated $150 additional cost for mileage and reproduction costs. This item is also budgeted in the 1991 budget at an amount of $4,500. Ken Maus emphasized the importance of developing a functional facility ratter than a hodgepodge of unorganized working spaces. In addition, he reviewed the importance of creating a green or site barrier between the public works facility and the adjacent residential area. Dan Blonigen suggested that the City Council and City staff can work together to best determine the needs of the public works department and that an architect will be needed only at such time that the building is designed. The representative from TKDA noted that some of the issues that would be addressed in the study would be 1) the viability of the existing site; is this the proper spot for the location of the public works facilities given the future growth of the community; 2) is it possible to split the public works facility into two locations, one near the industrial park and the other location to remain on Golf Course Road; or 3) maybe an entire new site is the best option given the residential character of the area where the existing public works buildings are located and given the development pattern in the community. Dan Blonigen noted that it's not that complicated. A consultant isn't necessary to determine an answer to the issues noted. He noted he would like to serve on any committee addressing the public works facility issues. Brad Fyle concurred that maybe a committee could adequately address the issuee. O O ®q Council Minutes - 7/8/91 John Simola responded by saying that the quote submitted by TKDA to do the study is an attractive price, but he is certainly open to addressing the issues via a committee made up of Council and staff. After discussion, a motion was made by Shirley Anderson and seconded by Ken Maus to table a decision to authorize TKDA to work with City sLaii toward development of a public works facilities plan and appoint a committee made up of Dan Blonigen, Brad Fyle, and City staff members to review public works facility preliminary issues and report back to Council. Motion carried unanimously. 0 C ,nc Council Minutes - 9/23/91 Z— Consideration of study for public works facility expansion. John Simola reported that at the direction of City Council, the public works facility building committee, consisting of Councilmember Blonigen, Counr_ilmPmhPr. Fyle, Roger Mack, and John Simola, had met and defined the issues to be studied with the public works facility expansion. After numerous meetings and tours of public works facilities in various other communities, the building committee has narrowed the focus of the proposed study. The subcommittee has concluded that the existing site has sufficient room for expansion of the public works department for the near and foreseeable future. Once the site nears or reaches capacity, it is likely that the sewer/water collection department would relocate, possibly to the industrial park near the reservoir. Therefore, the study will focus entirely on the existing site and existing buildings. The study will look at the possibility of joining the office of public works and garage for the sewer/water collection system with the existing public works shop under one roof. In addition, it will look at the possibility of adding onto the existing building or buildings individually. Simola went on to note that the public works facility building committee has recommended that the City contract with the engineering firm TKDA to conduct a public works facility expansion study at a lump sum cost of $2,750 plus expenses. City Council reviewed the scope of the proposed project. Brad Fyle noted that the City should stay away from using wood to heat the public works facility. Ken Maus noted his agreement, as the cost to use wood fuel in terms of labor could exceed any savings. John Simola responded by saying that due to the Dutch Elm disease problem, the City has a good supply of fire wood. This wood would otherwise be taken to the landfill, which results in a cost to the City. He noted that the burner would be designed to accommodate large pieces, and a process would be established to make the loading of the furnace as efficient as possible. It was the consensus of the Council to allow installation of a wood burning furnace if it could be demonstrated that it was cost efficient to provide supplemental heat to the building in this mannor. After discussion, a motion was made by Shirley Anderson and seconded by Clint Herbst to authorize the City of Monticello to contract with TKDA for a public works facility expansion study at a lump sum cost of $2,750 plus expenses as listed. Motion carried unanimously. 9 JUf1 12 •'32 122.1 Orr .,, •r r,,•.I nunvpin n•.�IX,c QNSA $Cr151C11 111111•r.11.

Public Hearinq--Consideration of a variance to the curbinq and hard surfacinq requirement. (J.O.) REFERENCE AND BACKGROUND: With the intensification or expansion of any site, the site must be reviewed in terms of its present conformance with the existing ordinance. when intensitication of the site occurs, those areas that are not In conformance are supposed to be brought up to code. In terms of the public utility expansion proposal, an aspect of the site is not in conformance with the ordinance. Specifically, the employee parking area is not presently bounded by curb, and it is not proposed that a curb be installed; therefore, a variance needs to be granted to allow this condition to exist. In addition, Planning Commission and City Council are asked to grant a variance which would allow use of an outside storage/drive area without paving the area. As noted earlier under the conditional use permit review, the area directly to the east of the exit will be used as a drive area and an outside storage area. A portion of the drive area will eventually be paved; however, it is not proposed that it be paved aL Lhls Lime becduse during phase II construction, which could occur in less than three years, a portion of the paved area will need to be removed. On past occasions, the City has allowed other businesses to delay paving of certain areas In anticipation of later development. The portion of the storage area is not proposed for paving whatsoever. It is not practical to pave this area because the area is used for short-term storage of construction material that should not be stored on a paved surface. Storing this type of material on a paved surfaco can result In damage to that surface during delivery and removal of the materials. It is, therefore, requested that a variance be granted to this paved surface requirement with a condition added that the City wet down the area In the event that dust becomes a problem. ALTERNATIVE ACTIONS: Motion to approve the variance request. Motion is based on the finding that the proposed variances will not 1) impair an adequate supply of light and air to adjacent property, 2) unreasonably Increase the congestion in the public street, 3) Increase the danger of fire or endanger the public safety, 4) unreasonably diminish or impair established property values within the neighborhood or in any other way be contrary to the Intent of this ordinance. Special Planning Commission Agenda - 6/15/92 Special Council Agenda - 6/15/92 Items 1, 2, and 3 above are self-evident. An applicant requesting a variance needs to demonstrate that either a hardship exists or the variance request does not impair the intent of the ordinance. Past precedent and interpretation of the ordinance indicates that variances from the hard surfacing requirement and curbing requirement are reasonable when it is demonstrated that future phasing will result in removal of curbing or parking areas. Due to the fact that there is no storm water drainage problem and, therefore, no practical need to install curbing along the employee parking area, it could be argued that granting a variance would not impair the intent of the ordinance. 2. Motion to deny the variance to the hard surfacing and curbing requirement. This alternative should be selected if Planning Commission and Council feel that the variance will result in diminishment of property values in the neighborhood or if the variances are inconsistent with the intent of the ordinance. C. STAFF RECOMMENDATION: Staff recommends alternative !1. D. SUPPORTING DATA: See conditional use Bite plan. 10 Special Council Agenda - 6/15/92 4. Consideration of rebuilding mixers for the Al diqester at the wastewater treatment plant. (J.S.) A. REFERENCE AND BACKGROUND: There are two draft tube type mixers In the first stage digester at the wastewater treatment plant. This digester is the only one with a fixed cover and, consequently, the only one that can be practically fitted with mechanical type mixers. One mixer has been in place since 1982 and has been in operation for 10 years. The second mixer was repaired under warranty and has been in operation for approximately nine years. PSG had roLed some vibration in one of the mixers and thought it best to pull one or both units for servicing. They took the opportunity to do so when we had Rocket Crane Service In town to unload our new concrete fuel tank for the public works building on Monday, June 8. What we found was somewhat surprising in that the propellers from both mixers had fallen off the ends of the shafts and were located somewhere in the bottom of the draft tubes or the bottom of the digester. The remaining portions of the mixers were found to be In need of major overhaul, including drive shaft replacement. NSG is in the process of preparing a list of parts needed, and it is hoped that the list will be available for Monday evening's meeting. It is safe to assume at this point in time that the cost to repair the mixers will be in excess of $2,000 and requires Council approval. Preliminary plans involve rebuilding both of the mixers and chocking to see if the propellers are caught within the draft tube or lying on the digester floor. If they are located in the draft tube mixer, they will have to be removed prior to installation of the rebuilt mixers. If they are believed to be on the bottom of the digester, they will not be removed at this time, as it Involves a significant project to completely drain the first stage digester. B. ALTERNATIVE ACTIONS: 1. The first alternative is to rebuild the draft tube mixers at an estimated cost of $11,911.54. It is Imperative that we have the draft tube mixers to koep the solids from settling out in the digester. IE 0 Special Council Agenda - 6/15/92 2. Alternative #2 would be to completely replace the draft tube mixers. It appears at this time that the units can be rebuilt; however, if upon further investigation and sandblasting of the parts it is found that many parts are no longer serviceable, it may be beat to replace one or both of the mixers if cost effective. At this time, cost estimates are rough only. The LLiid alLurnaLive ie Lu nuL replace Lhe drafL Lute mixers. This does not appear to be appropriate. C. STAFF RECOMMENDATION: It is the recommendation of the Public works Director that the City Council authorize refurbishing or replacement of the draft tube mixers as necessary under alternatives #1 or #2.
