PUBLIC HEARINGS None NEW BUSINESS ELECTION OF OFFICERS-- Motion by Yehle, second by Schmitt to nominate Ramsdell as Chairperson for 2003. All ayes. MOTION PASSED. PROPOSED SALE OF PROPERTY AT 3929 CALIFORNIA ST-- The now vacant City-owned property at 3929 California St. has been proposed for potential industrial development after it is sold to Glenn Stauffacher who owns Profile Tool and Engineering currently located at 3825 3ra St NE. The piece of property is zoned Industrial and it has been determined that the highest and best use of the property would be to develop it as light industrial. MN statute 462.356 requires that if a City has a Comprehensive Plan, it must notify the Planning Commission of the intent to purchase or sell land. The City Comprehensive Plan designates this property for parkland use, but the Planning Commission, Park & Recreation Commission and the City Council have all recommended to remove the park designation for this parcel. The City Comprehensive Plan also indicates that the loss of this'parcel will not have a detrimental impact on the future park system. The City has submitted a future land use change to the Metropolitan Council that would change the future status from parkland to industrial in anticipation of the proposed sale and development of this parcel. According to phone conversations with the Met Council, Planner Johnson expects this change to be approved 'without any problems. PLANNING & ZONING MINUTES MEETING OF JANUARY 7, 2003 PAGE 2 Motion by Ramsdell, second by Yehle, to support the action of the Columbia Heights Council to sell the property at 3929 California Street NE, as it is consistent with the City Comprehensive _Plan. All ayes. MOTION PASSED. PARK DEDICATION-- Planner Johnson explained that in 2002, the Planning & Zoning Commission and the City Council granted approvals for Parkside Village, a 25-unit market rate townhome subdivision adjacent to Sullivan Lake. In the process the Park dedication issue was discussed, and a decision was made to require $750 per unit for park dedication fees. Staff is requesting the Planning Commission review the current ordinance as it relates to park dedication and to compare other cities requirements in the Twin Cities area. The current ordinance language in 9.1403; Section 14: Subdivision Regulations: Page 14-7 creates some confusion over interpretations of what 'estimate of improvements' means. Planner Johnson provided the park dedications fees of several surrounding cities and noted that the fees vary tremendously. Staffwould like to see a consistent and fair amount set for both residential and commercial/industrial development and re-development projects. There was discussion regarding the fees for Residential Development. It was noted that some cities charge different fees for Residential based on whether they are single family homes, duplexes, apartments, or townhouses. Planner Johnson was asked when the comparable cities had passed their park dedication fees. The Commission members noted that the fees could already be outdated if established too long ago. He stated he did not know the dates that each city adopted these fees. After considering the comparisons supplied, it was the general consensus that $750/unit would be a fair fee and would be consistent with the fees being charged by New Brighton and Fridley, the cities closest to us. The Commission then discussed how Park Dedication fees should be established for Commercial/Industrial properties. Some cities charge a set fee per acre, and others charge a percentage of the market value of the unimproved land. The Commission members were concerned that a fair amount be set, so as not to turn away potential developers. The Commission felt that $2500/acre would be a fair amount compared to other cities. Councilmember Williams was present at the meeting and stated he thought that figure was too low. He felt something in the $6,000/acre range would be more equitable. He explained that based on current land values, if you went by a percent basis of the land value (5%), as some of the cities do, the amount would be closer to the $6,000 figure. As land values increase, using a percent basis would allow for increases of the fees without having to amend the Ordinance, as would be needed if a set fee is established. PLANNING & ZONING MINUTES MEETING OF JANUARY 7, 2003 PAGE 3 Community Development Director, Bob Streetar, questioned at what point the value of the land is determined. Is it before a property is purchased, after razing existing improvements, or after it is re-developed? Placing a value on property can be arbitrary, and the value could be different at each stage, therefore, language needs to established that will be clear in the amendment. Taking the comments into consideration, staff will draft an amendment to the current Ordinance and will bring it to the Commission in February for consideration. MISCELLANEOUS Councilmember Williams asked the Commission if they could possibly get involved in encouraging the sale of several properties within Columbia Heights that are currently unbuildable for various reasons. He would like to see that neighboring properties are offered these parcels so the City no longer has to maintain them, and they get back on the tax rolls. Staff will need to follow up on this and establish a list of the parcels before any action can be taken. Motion by Yehle, second by Schmitt, to adjourn the meeting at 7:50 pm../IH,lyes.

Case History: This will be the 14th year Linder's Greenhouses, Inc. will operate their greenhouse in Columbia Heights. ANALYSIS Surrounding Property: The property to the north and south of the subject parcel is zoned LB, Limited Business and is used commercially. The property across Central Avenue to the east is zoned GB, Retail Business and is used commercially. The area west of Central Value Mall is zoned R-2, Single and Two Family Residential and is used residentially. Case: 2003-0201 Page 2 Technical Review: Section 9.607 1)e of the Zoning Ordinance requires a Conditional Use Permit for seasonal agricultural sales. The attached site plan illustrates the configuration of two structures plus a patio area in front. This site plan and configuration remains unchanged fi:om previous years. A fence will enclose the patio and connect to each structure. The greenhouse structures will be the same as previous years with four, six foot doors remaining open at all times during business hours. There will be at least four fire extinguishers in the Flower Mart and all smoking will be prohibited. The principal uses of the subject parcel are preexisting and comply with zoning regulations. Existing parking exceeds zoning requirements, and adequate parking will be maintained after placement of the accessory structures over this portion of the parking lot. A narrative from Linder's Corporate Office is attached for your review. Please note that the Fire Department has reviewed the proposal and has expressed no concerns. Compliance with City Comprehensive Plan: The Land Use Plan Map designates this area of Columbia Heights for future commercial activity, including retail sales, offices, and service businesses. The proposal is consistent with the intent of the City Comprehensive Plan. Summary: The positive aspects of this petition are as follows: 1. The proposal is consistent with the Columbia Heights Zoning Ordinance. 2. The proposal is consistent with the intent of the City Comprehensive Plan. The negative aspects of this petition are as follows: 1. There do not appear to be any negative aspects. CONCLUSION Staff Recommendation: Staff recommends approval of the Conditional Use Permit provided a $500 deposit is submitted to the License/Permit Clerk prior to the installation of the structures on the site to ensure their removal at the end of the approved time period.

Site History: There are previous Planning Commission and City Council cases on this site. Site Plan Review was done in the early 1980's for this building. Several CUP's were approved for various uses in the 1990's. ANALYSIS Case: 2003-0202 Page: 2 Surrounding Property: The surrounding property on the south is zoned CBD and used for business purposes. The property to the north is zoned CBD, Central Business District, and is used for business purposes. The property to the east is Central Business District, and the property to the west is also zoned Central Business District. Technical Review: Section 9.1005 of the Columbia Heights Zoning Ordinance allows Vocational, Business, Performing, Visual, and Martial Arts Schools as permitted uses in the CBD (Central Business District). However, public or private K-12 schools are not listed as either permitted or conditional uses in this commercial district. Rather, public or private K-12 schools are allowed by conditional use in the Residential Districts. However, the zoning ordinance does provide the Zoning Administrator the ability to determine if uses not listed are appropriate and compatible with the district. Section 9.1002 reads as follows: Section 9.1002 General Provisions (6) Prohibited Uses: Any use not listed as either permitted, conditional or accessory in a particular district or any use not determined by the Zoning Administrator to be substantially similar to a use listed as permitted, conditional, or accessory shall be prohibited in that district. The Zoning Ordinance states that the 'Purpose of commercial districts are to provide for a wide range of goods and services in locations throughout the community; provide employment oppommities; and enhance the livability of the community by providing convenient access to goods and services'. The purpose of the CBD (Central Business District) is to provide for the development and redevelopment of the established downtown core, including a mix of retail, financial, office, service, and entertainment uses. The Zoning Ordinance also identifies specific development standards that apply to Schools, K-12 in Section 7; 9.701 (3) Page 7-20; these standards are: · The use shall include a regular course of study accredited by the State of MN- The Area Learning Center meets this requirement. · The site shall be served by a major collector or higher classification of roadway- Central Avenue is identified as a minor arterial roadway, and 40th Avenue is identified as a collector road. · The parcel upon which the use is located shall have a lot area no less than four (4) times the area of the building footprint - The current lot area is approximately (4) times the size of the building footprint. · To the extent practical, new construction or additions to existing buildings shall be Case: 2003-0202 Page: 3 complementary and compatible with the scale and character of the surroundings and exterior materials shall be compatible with those used in the immediate neighborhood - There are no plans to alter the appearance of the structural exterior of this space, other than signage and fagade improvements. An appropriate transition area between the use and adjacent property shall be provided by landscaping, screening or other site improvements consistent with the character of the neighborhood - Because the use is proposed on the second floor of an existing building, this requirement is not applicable. A transportation management plan shall be submitted to address off-street parking, bus loading and unloading, traffic control, and the impact of the facility on the surrounding roadways - The applicants have submitted a narrative that describes what is anticipated for parking needs and bussing. It is anticipated that one shuttle will be used for drop-offs and pick-ups twice through the day, which shouldn't create any traffic or transportation conflicts on site. The drop-off point for the facility will be on the north side of the building on 40th Avenue. The applicants have requested a conditional use permit to allow for what they believe is a similar and compatible use to the other uses in the district. Staff has reviewed the applicant narrative and attachments provided, and has these comments: The Area Learning Center proposed is a very vital community program. Staff is supportive of this location as it is located in an office type setting and within the con£mes of an existing building. Staff also had a chance to visit with the new owners of the property and they are confident that this program will be a good fit at this location. · K-12 School Programs are currently allowed by conditional use in Residential Zoning Districts. School District 916 believes Area Learning Centers can best survive and have success when located in non-traditional settings such as the Columbia Heights Business Center. · There are several Area Learning Centers located in commercial type settings around the Twin Cities area (see attachments). Nearby learning centers include the Mahtomedi Alternative Learning Center, the Alternative Learning Center in Champlin, the Alternative Learning Center in the Roseville Har Mar Mall, as well as several others in the Twin Cities area. · Staff members had a chance to visit the Mahtomedi Area Learning Center and learn about its programs. Staff was impressed with the facilities, and the Learning Center appeared to blend in well with its otherwise surrounding commercial environment. Parking requirements for a Senior High School are ten (10) spaces plus one space per every 6 students. With a projection of 150 students initially and a 200 student maximum, a total of 43 parking spaces would be required. Currently, the vacant office space requires approximately 40 parking spaces. This change in use would have virtually no impact from a parking standpoint as the adjacent parking ramp has enough spaces for this use. Also, the Area Learning Center will be Case: 2003-0202 Page: 4 located on the second floor or skyway level, which has direct access to the parking ramp and the outdoor patio area. The skyway access would be conducive for the school, as their students would be able to access the space directly from the parking ramp, without using the main lobby of the Northeast Bank space. The current vacant second floor space is approximately 12,000 square feet in size, and Metro 916 intends to revamp and redesign the interior of this space to meet its needs (see narrative). They are not proposing any structural exterior changes, except some signage improvements. The interior space will be revamped with demountable walls, which can easily be adjusted to meet changing space needs. Compliance with City Comprehensive Plan: The Land Use Plan Map designates this parcel for future commercial development. The Plan outlines several goals for land use in commercial areas. Two goals are: · Preserve and enhance the existing viable commercial areas within the community. · Enhance the image and viability of the Central Avenue corridor. Summary: The positive aspects of this proposal are as follows: · An Area Learning Center will provide a reuse for soon to be vacant second floor office space. · The Columbia Heights Area Learning Center is a beneficial and well-established program that is important to serving Columbia Heights students. CONCLUSION Sta_lCf Recommendation: Staff recommends approval of the Conditional Use Permit for the establishment of an Area Learning Center for Northeast Metro School District 916 at 3989 Central Avenue NE, as the Area Learning Center is a substantially similar and compatible use with the other uses in the Central Business District as determined by the Zoning Official. Recommended Motion: Move to recommend City Council approval of the Conditional Use Permit to allow for the establishment of an Area Learning Center for Northeast Metro School District 916 to operate at 3989 Central Avenue NE, as the Area Learning Center is: · A substantially similar and compatible use with the other uses in the Central Business District as determined by the Zoning Official.

We are completing the negotiation of a lease with Hempel Properties for approximately 12,200 square feet of space (ofa total of 16,000) on the second floor of the building. We have met with the City building inspector, Kevin White, at the Business Center, and will be building out the facility, either as part of the terms of the lease or as tenant improvements, to meet his specifications. I have attached our description of the ALC we propose to operate. Additional information for use in your consideration of our permit request include: 1. We intend to sign a lease with one sev .eh-year teai~ and one five-year tenant option. 2. The owner Will construct an exclusive ALC entrance on the northeast section of the plaza between the parking ramp and the building for use by students and staff. 3. We anticipate one shuttle bus from the Columbia Heights Schools to the ALC at approximately 8:00 a.m. and one return to the Columbia Heights Schools at approximately 2:00 p.m. each day. We propose to have the bus stop at the curb on the north side of the building. Bussed students will use the existing outdoor stairway to the second level plaza and the ALC entrance. 4. Should there be a student with a mobility disability, that student will use the first floor west entrance and elevator to reach the ALC. 5. Stu~lents driven to school by a non-student (generally parch0 will be dropped off on 40~ Avenue. They will be expected to enter the ALC via the outdoor stairway cited in #3. Partnerg in Educational Sneeialties 6. Students and staff parking will be in the ramp. They will utilize the ramp's stairways and walkways to reach the plaza ALC entrance. Based upon our experience with a similar sized program in Little Canada, we expect to use less than 50 parking spaces, out of the 400 existing in the ramp. 7. Students and staff, except as cited in fi4, will be required to use the outdoor stairs or ramp connection and to enter the ALC through the exclusive entrance. 8. The ALC will be operating Monday through Fridays for 225 days of the year. In addition, there will be some exclusively staffprofessional development days. 9. It is planned that a maximum of 125 students and 15 staffwill be in the ALC at any given point during the 8:00 a.m. to 8:00 p.m. instructional day. 10. Smoking will be confined to the northeast section of the outdoor plaza adjacent to the ALC entrance. 11. ALC staffwill provide reasonable general supervision within and around the building, including plaza and ramp. Staffwill be on site between 7:00 a.m. and 8:15 p.m. We understand that our request will be presented to the Columbia Heights Planning Commission at 7:00 p.m. on Tuesday, February 4. We also understand and appreciate the fact that the City administration will be recommending that our request be approved. Representatives of Intermediate District 916 will be at the Planning Commission meeting to answer any quegtions. Please advise me of any further information you require to consider this application. Sincerely, attachments: Creating a West Campus to the Northeast Metro Area Learning Center Draft Floorplan for ALC in Columbia Heights Business Center Area Learning Center West Campus Proposal. Creating a West Campus to the Northeast Metro Area Learning Center Northeast Metro 916 Intermediate School District 3300 Century Avenue North White Bear Lake, Minnesota 55110 Dr. Don E. Lifto, Superintendent Jessica Wiley, Director of Educational Services John Sedey, Area Learning Center Manager Area learning centers were created by the Legislature in 1987 as a component of Minnesota's open enrollment opportunities. From the original four "exemplary" centers established in the legislation, Minnesota now has over seventy. Area learning centers provide an option for students qualifying under the Graduation Incentives Program. Although area learning centers are generally associated with providing opportunities for students to meet high school graduation requirements, centers must also serve middle school students and may serve elementary students who meet qualifying criteria. The Northeast Metro Area Learning Center was established in 1992. It is located on Rice Street and County Road B-2 in Little Canada. The capacity of the facility is 300 students at any given time and 200 average daily memberships in a calendar year. Current enrollment is 286 students on site. In addition, facilitation of the Targeted Services program for interested member districts is provided, as well as the education component of area workforce centers' summer youth programs. Northeast Metro District 916 has been informed that a need exists on the west side of the district for area learning center programs and services similar to those offered at the Little Canada site. This need has been confirmed based upon discussions with the local school district leadership. Page 1 Area Learning Center West Campus Proposal The purpose of this proposal is to document the need and support the development of a west campus of the Northeast Metro Area Learning Center to open for students in the fall of 2002. h 1987, ~e ~nnesota ~gislature established ~ts for four ~ea le~ing centem to be developed. ~ey were to demons~ate successful tech~ques for se~ing "at risk" lerner. These original four "exempl~" ~ea le~ing centen were located in the C~er-Scott Cooperative Center, Mounds View Schools, North Brach Schools, and Sr. Cloud Schools. Following their development, implementation, ~d extensive evfluation, the concept of mca leming centers was embraced by ~e Dep~ment of Education for ~ssemnafion mound the state. Area learning center attendance is an option for students, generally under the age of 21, who qualify under the Graduation Incentives Program by meeting at least one of the following criteria: performs substantially below the performance level for pupils of the same age on a local achievement test · is at least one year behind in satisfactorily completing coursework or obtaining credits for graduation · is pregnant or is a parent · has been assessed as chemically dependent is a victim of physical or sexual abuse · has experienced mental health problems · has experienced homelessness sometime with the last six months · speaks English as a second language or has limited English proficiency · has been referred by a school district for enrollment in an eligible program · has withdrawn from school or has been chronically truant has been excluded or expelled Area Learning Centers provide: · academic and life skills taught using nontraditional methods · trade and vocational skills training · career exploration and opportunities for work experience, applied learning, work-based learning, school-based learning and youth services Page 2 .hi 9x6 Area Learning Center West Campus Proposal · transition services which assist learners to progress from school-to-school, school-to- work. or school-to-post-secondary institution · support services to assist learners in solving personal and social issues · access to regular school programs · access to Post-Secondary Enrollment Options, allowing juniors and seniors to attend post-secondary institutions and receive high school credit Students may choose to receive their diploma from either their home district or the district in which the area learning center is located. Area learning center credits are transferable to any school district. There are currently over 70 area learning centers in Minnesota. Alternative programs, including area learning centers, enroll over 150,000 students each year. In 1992 one of the member districts proposed that Northeast Metro District 916 develop an area learning center. Following a feasibility study, the Northeast Metro Area Learning Center was established. It began serving students in the Capitol View Center in Little Canada in September of 1992. In the View. · · · · · fall of 2002 the Area Learning Center moved into a newly remodeled section of Capitol Currently the Area Learning Center: operates in 9,500 square feet of space is staffed by 17 teachers and support staff serves 200 average daily memberships each year, excluding satellite programming provides learners with the opportunity to achieve 24 Graduation Standards is open from 8:00 a.m. to 8:00 p.m. Monday through Thursdays, and from 8:00 a.m. to 2:00 p.m. on Fridays during the school year and 8:00 a.m. to 2:00 p.m. Monday through Fridays during the summer serves learners 225 school days per year provides school-based and community-based programming offers carefully guided independent study to learners over 16 who demonstrate they can manage it provides a mainstream program for special education students who meet area learning center criteria provides a full middle school program for students for whom a comprehensive referral establishes such a program is necessary Page 3 Area Learning Center West Campus Proposal · facilitates the provision of Target Services for a member district In January 2002 leaders of the Columbia Heights Schools visited the Northeast Metro Area Learning Center. After establishing the compatibility of philosophy regarding services to at risk learners, they inquired about the possibility of transporting its alternative program students to the Capitol View site. However, Capitol View is, and has been for the past four years, at capacity, and could not accommodate the approximate 120 learners who are, or have requested, services in Columbia Heights. Therefore, the consideration of developing a west campus is taking place. The process to date has been: · discussion with leadership of Northeast Metro and Columbia Heights regarding interest · establishment of initial potential numbers of students · creation of financial scenarios · development of preliminary development timeline · initiation of a search for available space Through the meetings with the Columbia Heights District leaders it has been established that there are currently 90 students in their alternative program, which would be closed upon the creation of the west site. In addition, there are 30 students on a waiting list. Using this information, and extrapolating based on the past 5 years' experience at the Northeast Metro Area Learning Center, it is projected that a west site would serve 150 average daily memberships in its initial year, reaching its capacity of 200 by the third year. Because the Area Learning Center operates on a 12-hour day and year round, the maximum number of students on-site at any given point would be approximately 125. The situation with the proposed west site is similar to that of the Capitol View site. The districts surrounding Capitol View all have area learning centers or alternative programs, yet the Northeast Metro Area Learning Center continues to operate at capacity. Strong programming, committed staffing, good location, and fiscal responsibility lead to being able to offer a competitive operation. The districts surrounding the proposed west site have successful alternative programming in place. However, with the core Columbia Heights student population and the application of the principles that make the Capitol View site successful, there is no doubt the west site will be successful financially, as well as programmatically. Page 4 __ Area Learnin___g Center West Campus Proposal Given approval to proceed with the development of a west site for the Northeast Metro Area Learning Center, the following strategies and activities would need to take place prior to its opening: 1. Develop a proposal, including financial scenarios, for approval by the leadership of the Columbia Heights Schools and the board of Northeast Metro District 916. 2. Identify available space, with reasonable lease and projected buildout costs, for a west site. 3. Establish an overall advisory group, including Columbia Heights leadership, to guide the development of the project--anticipate minimum of monthly meetings. 4. Establish and implement an operational plan for facilitation of Columbia Heights summer programs and Targeted Services. 5. Complete the design and cost for buildout. 6.

Case History: There is one previous Planning and Zoning Commission case on the property. A conditional use permit was granted in 1999 to allow fora monopole telecommunications tower on the site. ANALYSIS Surrounding Property: The surrounding property in all four directions is zoned and used residentially. Case: 2003-0203 Page: 2 Technical Review: The Minneapolis Water Works has proposed to implement a new membrane filtration water treatment process on the site of their existing facility located off of Reservoir Boulevard. This new system will ensure the delivery of safe drinking water to its customers. In moving forward with this project, the MWW approached City staffin 2001, and also briefed the City Council on proposed plans for the site. ~T~a_e.proposal includes an at-grade 65~000 square foot sinEle-~tory steel flamed and masonry structure that will house offtce.q~ conference fa~cilitie.q~ equi~ an~d .hSYmbran__.____..._eee filtration treatment units._ The 55,000 square foot basement will housetmmpj~ equipment, piping/valves, cranes~ and ¢-he~---C-~stora~ and feed facilities. The proposed 6on,traction schedule from start to completion is 18 months, begirming this~pri~g. ' The proposal includes consistent__b_uilding ' 'th the existing wBter treatment ~ surr~afliagar~a. The renderings provided include elevations of what each' building side will generally look like. The building materials will consist of face brick veneer, complemented by cast stone eyebrow and cornice features, as well as keystone block. The roof will feature an attractive clay tile roofing system. The rooftop venting and mechanical units will be, h~__appropriately screened from view. The outside transfo~_~rs and engine generat0fs-~L~I-a~_ be appropriately ~ md not visible or audible from adjacent Properties. The new b~n~g · itself is an enclosed high tech and highly secured facility, which should not generate additional noise or traffic to surrounding properties other than during construction. It should be noted that the b~____uilding will not be more than 25 feet in height; less than the 35 foot requirement. Non-residential building setbacm: · Minimum front yard building setback is 25 feet; The proposed building far exceeds this requirement as it is a couple hundred feet from the front entrance. · Minimum side yard building setback is 40 feet; The proposed building far exceeds this requirement as it is approximately 200-300 feet from the nearest west residential property, and is approximately ¼ mile fi.om the east properties. · Minimum rear yard building setback is 40 feet; The proposed building far exceeds this requirement, as it is approximately ¼ mile fi.om the north properties. Non-residential parla'ng setbacks: · Minimum requirements are met with parking arrangements proposed. Parking requirements for maintenance facilities are one per 3,000 sf of floor area, plus one per 300 sfofoffice area. Based on this formula, the total number of parking spaces required for this facility is 26. The proposed plans show 28 parking spaces, with possible room for more if needed. The site plan proposal includes several landscaping sheets, which provide details on plant and tree numbers, locations, and species. The ordinance requires a minimum of one tree for every 50 feet of street frontage, or a minimum of 4 trees for every one acre of lot area covered by buildings, parking area, etc. The landscaping plan provided includes approximately 153 Case: 2003-0203 Page: 3 deciduous, coniferous, and evergreen species, as well as approximately 225 shrubs of various species. This plan more than meets the minimum landscaping standards established by the ordinance. A majority of the tree plantings will be a natural buffer for the residential homes on the west side of the MWW site, but additional trees will be interspersed at various locations on the site (see landscaping plans). Public Works Director Kevin Hansen has reviewed the plans submitted and has been in contact with MWW staffand consultants since 2001 on various site issues. It appears from Mr. Hansen's analysis that on-site surface water ponding has been Proposed for the site, and is required by ordinance. Also, it appears that a new sanitary sewer and water line (looped) are proposed and have been reviewed and preliminarily approved by Public Works. The Fire Department has also reviewed and preliminarily approved the plans with some comments (see attached). Compliance with City Comprehensive Plan: _The 2001 City Comprehensive Plan designates the property for future public use by the City of ,Mirmeapolis Water Works. Summary: The aspects of this proposal are as follows: · The new water treatment facility will ensure delivery of safe drinking water for Columbia Heights residents. · The treatment plant proposed features varied architectural patterns designed to blend in with existing buildings on site and with the surrounding area. CONCLUSION Staff Recommendation: Staff recommends approval of the Site Plan orooosal for the Minneapo~lis Water Works site on property at 4700 Chatham Road. _ _ Recommended Motion: - Move to approve the Site Plan proposed ~r"a-65,000 square fdot water treatment facility on the Minneapolis Water Works property at 4700 Chatham Road, subject to the following conditions: 1. All required state and local codes, permits, licenses and inspections will be met and in full compliance. 2.

The new process will utilize membrane filtration water treatment units to achieve a higher level of microbial removal than currently possible at higher production rates. Representatives from the City of Columbia Heights and the Minneapolis Water Works (MWW) have met on several occasions through out the design process to gain input on issues important to Columbia Heights. One of the pdmary goals established by the MWW for this project, is to remain a good neighbor to the area residents. Following is a bdef overview of the project. The new facility will be located on the southwestem portion of the existing plant site and will consist of a 55,000 sf cast-in-place concrete basement to house pumping equipment, piping/valves, cranes, and chemical storage and feed facilities. An at-grade 65,000 sf single story steel framed and masonry superstructure will house offices, locker rooms, conference facilities, electrical and mechanical equipment, as well as 36 membrane filtration water treatment units. The new facility Iocadon was selected to facilitate piping and utility connections to the existing water treatment plant while allowing space for potential future treatment facilities. The set backs were selected to maintain the park-like setting of the site while achieving fore mentioned operational needs. The building architecture (masonry with precast copings and clay tile roofing accents) was selected to blend with the existing water treatment plant buildings and the surrounding neighborhood. The site layout and landscaping plans were developed to minimize disruption of the site. The storm water system was designed to utilize overland flow through grass swales for sediment removal. A normally dry storm water detention pond is planned for the southern portion of the site and a wet pond planned for the northern portion of the site. The ponds are sized to avoid impacting the existing City of Columbia Heights storm sewer system. The existing drainage features and topography allowed the use of the dry pond, which will minimize disruption of the site. The wet pond (north central portion of the site) will replace an existing wet pond, which is currently located near the western property boundary. A significant change in the number of staff located at the plant site is not anticipated. Rather, current staff will likely assume the duties of operating the new membrane facility. In addition, the volume of operations and maintenance related traffic is not expected to significantly change. CITY OF COLUMBIA HEIGHTS Public Works Department TO: TIM JOHNSON CITY PLANNER FROM: SUBJECT: DATE: KEVIN HANSEN ~ PUBLIC WORKS DIRECTOR/CITY ENGINEE MINNEAPOLIS WATER WORKS MEMBRANE FILTRATION PLANT January 22, 2003 Introduction: The Minneapolis Water Works (MWW) attended the September 4th, 2001 City of Columbia Heights Council Work Session to provide background information and discuss their plans to construct a membrane filtration plant at the Columbia Heights site, located north of 45th Avenue and Reservoir Boulevard. The MWW supplies potable water to the City's of Minneapolis, Bloomington (partial), Crystal, New Hope, Golden Valley, Columbia Heights and Hilltop. The source water is the Mississippi River. The Fridley SoRening Plant processes the raw water and then sends it to either the Fridley Filtration (2/3) or Columbia Heights Filtration (1/3) Plants for finishing and distribution. This form of treatment requires significant chemical processing including chlorine, ammonia and polyphosphates. Because of health related outbreaks in the 1990's from surface water sources, the Federal EPA has mandated complete removal or inactivation of these contaminants. The membrane or Ultra Filtration that the MWW has designed can accomplish this. Following the September 2001 presentation by the MWW, Engineering staff followed up with a list of questions to the Director of the Water Works. Attached is a copy of that letter and the MWW response to each question. Analysis: The construction plans have moved along to the point of site/civil reviews by engineering staff and are currently at 90/95% complete. The new facility is also subject to building plan approval through the permitting process by the City of Columbia Heights. Public Works/Engineering has provided preliminary comments to the Consulting Engineers working on the site/civil plan. The site/civil will incorporate large on-site ponding to meet or exceed the City of Columbia Heights requirements for surface water. The new plant will have minimal sanitary sewer discharge (no capacity impacts) with a new sanitary sewer line to be constructed near Reservoir Boulevard and Johnson Street. A new water main will be looped inside the facility to provide additional fire hydrants, based on a recommendation from our Fire Department. The new building will be a single story with a full basement with a building footprint of approximately 65,000 square feet. The exterior construction materials will be entirely masonry, closing matching the existing building(s) brick exteriors. The proposed construction schedule provides an 18- month construction timeframe to completion, beginning this spring. Due to the nature of the construction, truck traffic will be an issue and routing will have be determined prior to construction. Staff would recommend state-aid routes such as Central Avenue, 44th Avenue, and Reservoir Boulevard for all truck and construction related traffic. Significant landscaping is also proposed as part of the Building Project. The landscaping design incorporates native species wherever possible and can be divided in to two main areas of the site: 1. Front Entrance: Aesthetic focus blending shrubs and ornamental trees. 2. Residential to the west: Screening focus incorporating deciduous and coniferous over story trees. For areas outside the construction boundaries, existing trees are intended to be marked and preserved. Representatives from the Minneapolis Water Works and Design Consulting Engineers will be present to make a brief presentation, provide additional plan information of the design of the plant, construction schedule and respond to questions or obtain additional input for the final design of the new membrane filtration plant.

Public Works Director/ City Engineer City of Columbia Heights 637 - 38th Avenue N.E. Columbia Heights, MN 55421-3806 Dear Mr. Hansen: This letter is in response to your letter dated September 7, 2001. I welcome your comments and questions which you raised in your letter. The City of Minneapolis, after spending several hundred thousand dollars and more than seven years o[ studies and investigation, has reached the conclusion that membrane filtration is the most reliable available technology to provide a physical barrier to microorganisms in water. We at the Minneapolis Water Works are very excited in regard to this project and want to let you know that the City of Minneapolis has committed more than $140M to improve the water treatment facilities that supply water to its citizens and the suburbs which get our water. I have addressed each question or comment in the same order as mentioned in your letter: This will be addressed during contract negotiations with the City of Columbia Heights. The major source of noise will be due to air compressors and the effect on the surrounding area will be minimal due to the fact that the equipment will be housed in the building. No additional waste, since the existing filtration plant will be :'decommissioned, the new facility waste generation shall substitute the old plant. The major maintenance requirement for a membrane fil:ration plant is replacement of broken fibers. A.'firmative Action Employer o The daily traffic to the facility will not increase. There is the possibility of less chlorine usage which would reduce traffic. o The auxiliary or backup power will be addressed with the design engineering firm. The noise issue also will be addressed. °' The building will be decommissioned. We are not planning to demolish it. We are looking into the possibility of other usage. The quality of water supplied to the City of Columbia Heights by the membrane filtration plant will exceed the existing USEPA regulations. 9, No. 10. The major improvement will be minimization of microorganisms such as giardia and cryptosporidium from finished water. 11. It is important to us that the. new plant building blend with the existing buildings. If you are interested in our design phase, your input could be included in the design of the 'facade of the new building. 12. There should be no changes to the chemical characteristics of the finished water. 13. No. I hope these responses clarify some of your concerns. I welcome you and other City officials to visit the pilot plant at Columbia Heights Filtration Plant to see this technology. Please feel free to contact me at 612-673-2418 if you have any questions.

Durin=~ the past ! 29 ygars it has developed from a single pump station, taking water ~rom the Mississippi River at Fifth Avenue South and delivering it to a small distribution system, to the largest water utility in the upper Midwest with approximately !,000 miles of pipe in the distribution system. The sole source of water supply for the MWW is the Mississippi River with an average annual withdrawal of approximately 25 billion gallons. The MWW produces an average of 70 million gallons per day. Peak rates in the summer are as high as 180 million gallons per day. The current treatment system utilizes lime softening, conventional iiifi~! HI[ration, and chloramine disinfection processes. The Minneapolis Water Works has nvo treatment facilities, the main plant at Fridley and a smaller capacity plant at Columbia Heights. The Fridley Softening Plant processes all of the raw water for both the Fridley Filtration Plant and the Columbia Heights Filtration Plant. Chemical treatment at the Softening Plant consists of lime, alum, carbon, potassium permanganate, carbon dioxide, and calcium carbonate. Softened water is routed to either (or both) the Columbia Heights Filtration Plant or the Fridley Filtration Plant. At tile Filtration Plants, water is filtered through sand media. Chemical treatment at the Filtration Plants consists of chlorine, ammonia, fluoride, ferric chloride, and liquid polyphosphate. Tile usable finished water reservoir storage capacity equals one and one half days of average daily demand. A new reservoir is currently under construction that will bring the finished water storage capacity to two days of average daily demand. In 2007, another new reservoir is scheduled for construction, which will increase tile storage capacity by another one-half ora day. The distribution system includes 14,000 valves, 8000 fire hydrants, and over !,000 miles of cast iron, ductile iron, and steel watermain pipe. Since the cryptosporidium outbreak in Mihvaukee, WI, in 1993, there has been an increased awareness of this health hazard. The upcoming EPA Enhanced Surface Water Treatment Rule (ESWTR) requires complete inactivation or removal of these contaminants, and membrane ultrafiltration can accomplish this. Tile Minneapolis Water Works with the technical assistance of the engineering consulting firms of HDR Engineering, Inc. and Malcolm Pirnie condu6ted a treatment feasibility study for the Water Works. A number of alternatives were considered including ozone disinfection, which provides cr>.'ptosporidium inactivation but has other operational problems. The feasibility study recommendation was to install an ultrafiltration m~mbrane plant at both the Columbia Heights Filtration Plant (CHFP) and tile Fridley Filtration Plant (FFP). Tile Value Engineering Study by six environmental engineering consultants and a Citizen's Advisory Committee (which included members ,"rom the health communi .ty, suburban customers, and Minneapolis citizens) reviewed and concurred with the recommendation for an ultrafiltration membrane system for the Minneapolis Water Works facilities. The results of thc Value Engineering Study were presented to Minneapolis' Mayor and City Council. As a result, the Ultra Filtration Program was approved (in 2000). Tile ultrafiltration program for the removal of microbial contaminants at the Minneapolis Water Works includes the following: · Performance testing and selection ora membrane supplier for the Columbia Heights facility, based on the capacity, performance, energy consumption, cost, and other parameters of various manufacturers' units. This is currently undenvay · Construction ora 70 million-gallon per day system at Columbia Heights site.
