Vacation of Existing Drainage and Utility Easement at 1515 44th Avenue NE Introduction: Brandt stated in 2025 that Duffy Development Company, Inc was selected by Anoka County, the property owner of 1515 44th Avenue NE, to redevelop the lot into an affordable apartment building. The applicant approached Staff to discuss possible options that would be compliant with the current City Code. During this discussion, the applicant noted that the lot had existing easements that, if maintained, would hinder the process of redevelopment. Brandt explained that upon review, the applicant and staff determined that the “utility and drainage easement” labeled Easement ‘B’ is the fire lane easement that allowed fire truck access around the assisted living facility on the adjoining property. A land survey was conducted it was determined that the constructed fire lanes are misaligned with the easements. Brandt reviewed the current status and noted that staff have coordinated with City Engineering and the City Fire Chief to confirm the findings. Comments are attached to the Agenda Packet. Staff will continue to work to ensure that all requirements will be met in the redevelopment of the site for access to the buildings on the adjoining properties. Attached to the Agenda Packet is the plat and land survey identifying the easement to be vacated. Once approved, the applicant is responsible for filing the vacations with Anoka County. Brandt stated the Zoning Ordinance requires the Planning Commission to hold a public hearing on the application for the vacation of a street, alley, or other public right -of-way and submit its recommendation to the City Council. The subject property at 1515 44th Ave NE is zoned R-3 Limited multiple-family residential. The surrounding area is zoned residential, R-3 to the east, R-2A - two-family residential to the west, and R-1 - single-family residential to the south, with open space to the north. Brandt noted that the City’s 2040 Comprehensive Plan guides the subject sites as “High Density Residential” as well as the area to the east, “Low Density Residential” to the south and west, and “Park” space to the north. She reviewed the findings of fact. Section 9.104 (J) of the Zoning Ordinance outlines certain findings of fact that must be met in order for the City to grant approval for an easement vacation. The findings are as follows: The City Council shall make each of the following findings before vacating a street, alley, or other public right-of-way: a) No private rights will be injured or endangered as a result of the vacation. This is correct. 25 Item 3. City of Columbia Heights MINUTES April 07, 2026 Planning Commission Page 3 b) The public will not suffer loss or inconvenience as a result of the vacation. This is correct. Questions/Comments from Members: Schmitz asked if the proposed easement would affect the easement in block two. Brandt replied that it would not affect the block, and the request was strictly for block one. Maameri asked if the Fire Department had any concerns that were resolved. Brandt replied that there were no concerns. Maameri pointed out that the applicants have determined utility and drainage easement and wondered if the fire lane easement allows fire truck access to the assisted living facility. Brandt replied that the Fire Department is still using the paved fire lane, and they will work with the applicant to ensure that the fire lane can be used during construction. Public Hearing Opened. Christopherson opened the Public Hearing. There were no public comments. Public Hearing Closed. (Commissioner comments, if any) Motion by Christopherson, seconded by Moses, to close the public hearing. All ayes. MOTION PASSED. Motion by Moses, seconded by Schmitz, to recommend that the City Council approve Resolution 2026- 019, vacating the drainage and utility easement, easement ‘B’ at 1515 44th Avenue NE as presented. All ayes. MOTION PASSED. Motion by Christopherson, seconded by Moses, to waive the reading of draft Resolution 2026 -019 there being ample copies available to the public. All ayes. MOTION PASSED. 6. Variance for reduced parking requirement for 999 50th Ave NE Introduction: Brandt stated in 2016 that the last remaining tenant, a dental office, vacated the property at 999 50th Avenue, resulting in the building remaining fully vacant to the present day. Over the past decade, City staff have received multiple inquiries regarding potential redevelopment of the site; however, none have advanced to an approved or completed project. Brandt noted that in 2022, A & A Properties acquired the subject property and initiated an evaluation of potential uses for the existing building. The applicant has engaged in ongoing discussions with City staff to identify site constraints and applicable regulatory requirements. Staff has advised that any proposed use would require the building to be brought into compliance with current building and fire codes, including accessibility requirements under the Americans with Disabilities Act and the installation of an approved fire suppression system. 26 Item 3. City of Columbia Heights MINUTES April 07, 2026 Planning Commission Page 4 Brandt explained that based on these discussions, both staff and the applicant have concluded that establishing a viable use within the approximately 12,000 square foot building would present significant challenges. Specifically, compliance with applicable health and safety standards, in combination with the need to maintain a parking demand not exceeding 41 spaces, substantially limits feasible reuse options for the property. Brandt stated A & A Properties is requesting approval of a variance from the off-street parking requirements for the property located at 999 50th Avenue NE. The applicant is proposing to establish a café/restaurant (food service, full-service) within the existing building. For this use, City Code 9.106 (L), requires off-street parking equal to 30 % of the building’s occupant capacity, which results in a requirement of 53 parking spaces. The subject property currently contains 41 parking spaces, resulting in a deficiency of 12 spaces. The applicant seeks a variance f or the following: 1. Variance to allow a 12-space reduction in required parking, from 53 to the existing 41 parking spaces. Brandt noted that the Zoning Ordinance requires the Planning Commission to hold a public hearing on the application for the variance and submit its recommendation to the City Council. The subject property is zoned GB (General Business), and the surrounding area is zoned GB to the east and north, with R-2B (One and Built as Duplex Residential) to the south and R-2A (One and Two Family Residential) to the east. The use of the property as a business and food service complies with the Zoning Code and is otherwise code-compliant. Brandt mentioned that the City’s 2040 Comprehensive Plan guides the subject site as “Commercial” as well as the area to the south, east, and north, and the west as “Medium Density Residential”. The proposed use and parking variance is consistent with the goals and intent of the Comprehensive Plan. Brandt stated that staff have reviewed the variance materials submitted, including floor plans, applicant narrative, and site plan illustrating the proposed use of the building and its relati on to adjacent properties and structures, as well as the existing parking associated with this property. Brandt reviewed the findings of fact. Section 9.104 (G) of the Zoning Ordinance outlines required findings of fact that must be met for the City to grant approval for a Variance. The findings are as follows: The City Council shall make each of the following findings before granting a variance: a) Because of the particular physical surroundings, or the shape, configuration, topography, or other 27 Item 3. City of Columbia Heights MINUTES April 07, 2026 Planning Commission Page 5 conditions of the specific parcel of land involved, strict adherence to the provisions of this article would cause practical difficulties in conforming to the zoning ordinance. The applicant, however, is proposing to use the property in a reasonable manner not permitted by the zoning ordinance. This is correct. Strict adherence to the off-street parking requirements would result in practical difficulties due to the specific conditions of the subject property. The existing building occupies a significant portion of the site, and the parcel is further constrained by surrounding development, limiting the ability to expand or reconfigure the site to accommodate additional parking. In addition, since the construction of the building, the City’s zoning ordinance has been amended, resulting in increased parking requirements. As a result, if the entire building is utilized only three uses allowed in the General Business District could meet current parking standards on this property. Despite these constraints, the applicant is proposing a reasonable use of the property by establishing a café/restaurant within the existing structure, which is consistent with the intent of the zoning district. b) The conditions upon which the variance is based are unique to the specific parcel of land involved and are generally not applicable to other properties within the same zoning classification. This is correct. The site contains an existing building that occupies a substantial portion of the parcel, limiting opportunities for site modification. In addition, physical constraints, including a change in elevation between the subject property and adjacent parcels, restricts the ability to expand parking or establish shared parking arrangements with neighboring properties. These site specific conditions distinguish the property from others in the General Business zoning district. c) The practical difficulties are caused by the provisions of this article and have not been created by any person currently having a legal interest in the property. This is correct. The practical difficulties are not caused by the current property owner or any person having legal interest but due to changes in the zoning code. d) The granting of the variance is in harmony with the general purpose and intent of the Comprehensive Plan. This is correct. The Comprehensive plan calls for reinvestment, renovation, and modernization of the City’s commercial districts. e) The granting of the variance will not be materially detrimental to the public welfare or materially injurious to the enjoyment, use, development or value of property or improvements in the vicinity. 28 Item 3. City of Columbia Heights MINUTES April 07, 2026 Planning Commission Page 6 This is correct. The granting of this variance will result in a new res taurant in a building that has been left vacant for more than a decade. Questions/Comments from Members: Moses asked staff if there was concern about overflow into the Aldi parking lot. Brandt replied that there have been no comments from Aldi, and Aldi received a notice. Maameri asked if there was an ability to have on-street parking. Brandt replied that on-street parking is available outside of the building. She added that staff could work with the Engineering Department to discuss any concerns with the intersection. Moses asked how long the process would take. Forney invited the applicant to speak. Daniel Shay explained that they have not done much planning since they were waiting for approval from the City. The design process will begin after the approval. Maameri clarified that the applicant is asking for a reduction of 12 parking spaces. Brandt agreed. Christopherson added that it is based on the occupancy. Public Hearing Opened. Christopherson opened the Public Hearing. There were no public comments. Public Hearing Closed. Motion by Schmitz, seconded by Christopherson, to close the hearing and waive the reading of draft Resolution No. 2026-026, there being ample copies available to the public. All ayes. MOTION PASSED. Motion by Maameri, seconded by Moses, to recommend that the City Council approve Resolution No. 2026-026, a Variance allowing a 12 parking space reduction for 999 50th Ave NE, Columbia Heights, MN 55408. All ayes. MOTION PASSED. OTHER BUSINESS Brandt stated that the May Planning Commission meeting has been cancelled. She added that there are no new applications. Staff is looking to schedule the kick-off meeting for the Planning Commission and the Advisory Committee for the Comprehensive Planning process for May 6 th. Forney added that the City has pushed forward a Parks Master Plan. He mentioned that the 4300 Central Avenue project is moving forward, and the developer is currently working on the Environmental Assessment Worksheet. Christopherson asked if there had been any progress with the Medtronic site. Forney replied that the brokers are in conversation with other developers for the site. City staff is meeting with the brokers and MnDOT to see if a portion of the property could be used for stormwater ponds. 29 Item 3. City of Columbia Heights MINUTES April 07, 2026 Planning Commission Page 7 Maameri pointed out that the building across the street from City Hall had been sold. Forney agreed and explained that the Fairview building has been sold, and the new building is proposed to be a clinic. Councilmember James mentioned that there would be a Boards and Commission reception at City Hall on April 15th at 5:00 pm. ADJOURNMENT Motion by Christopherson, seconded by Moses to adjourn the meeting at 6:24 pm. All ayes. MOTION PASSED Respectfully submitted, __________________________________________ Ursula Brandt, City Planner 30 Item 3. V PLANNING COMMISSION AGENDA SECTION PUBLIC HEARINGS MEETING DATE JULY 7, 2026 ITEM: Consideration of a Variance for reduced parking lot setback for 81 38th Ave NE. Presenting Item: Ursula Brandt, City Planner DEPARTMENT: Community Development BY/DATE: Ursula Brandt, City Planner, 6/10/26 CORE CITY STRATEGIES: (please indicate areas that apply by adding an “X” in front of the selected text below) X Community that Grows with Purpose and Equity _High Quality Public Spaces _Safe, Accessible and Built for Everyone _Engaged, Effective and Forward-Thinking _Resilient and Prosperous Economy _Inclusive and Connected Community CASE NUMBER: 2026-PZ05 APPLICANT: Millie Kwatt LLC LOCATION: 81 38th Ave NE, Columbia Heights, MN 55421 BACKGROUND: The applicant owns the building at 81 38 th Ave and have run a successful business in this location for decades. In 2012, the applicant first asked for a variance to the parking setback to accommodate the addition of a parking lot to the west of the building. The original request (granted through resolution 2012-050) was to allow for a 0.5ft setback from the side property line to accommodate 18ft by 9ft parking spaces and a 24ft drive aisle. The current request is for a 0 ft setback from the side property lines to accommodate an accessible sidewalk leading to the west entrance along with 18ft by 9ft parking spaces and a 24 ft drive aisle. As noted in 2012, and is still relevant today, a vacation of the California Street right-of-way conducted in the 1990s. The result of the vacation gave an additional 30 ft of land to the subject property . Upon review of the area, it was discovered that there are some city utilities along the right-of-way, but they are buried deep enough to accommodate the construction of a parking lot. The applicant is utilizing the building for office and warehousing. The City Code requires 1 parking s pace for each 300 sqft of office space and 1 parking space for each 3,000 sqft of warehousing. The building has 1,500 sqft of office and 4,500 sqft of warehouse, requiring 7 parking spaces. Currently, the property utilizes approximately 11 parking spaces along the south side of the building, all of which are legal non-conforming for setbacks, and none are handicap accessible. The applicant would like to accommodate more parking on the property by constructing a 5 parking space parking lot to the west of the build ing which includes one handicap accessible parking space located in front of the main entrance to the building. City Code 9.111(C) requires parking areas to be no closer than 20 ft from the front property line, and 5 ft from the side and rear property lines. City Code 9.106(L)(7) prescribes parking spaces to be a minimum of 9 ft wide and 18 ft deep when abutting a curb, and the drive aisle width to access the parking spaces can be no less than 24 ft. To 31 Item 4. Page 2 accommodate the new parking lot the applicant is seeking a variance for the following: 1. Variance to allow for a 0 ft parking lot setback on the west and north property lines and an increased amount of 0 ft setback on the east property line. ZONING ORDINANCE The Zoning Ordinance requires the Planning Commission to hold a public hearing on the application for the variance and submit its recommendation to the City Council. The subject property is zoned I-1 (Industrial), the land to the south and west are also zoned I-1 while the north is zoned PO (Parks and Open Space) and to the east is R3 (Limited Multi-family Residential). The current use of the property as a business complies with the Zoning Code and is otherwise code compliant. COMPREHENSIVE PLAN The City’s 2040 Comprehensive Plan guides the subject site as “Industrial” as well as the area to the south and west. Consistent with the zoning discussed above the Comprehensive Plan guides the property to the north as Open Space and the east as Low Density Residential. A variance to allow for more parking to accommodate the existing use is consistent with the goals and intent of the Comprehensive Plan. CURRENT STATUS Staff has reviewed the variance materials submitted including applicant narrative, site plan and survey illustrating the proposed parking lot and its relation to adjacent properties and structures as well as the existing parking associated with this property. FINDINGS OF FACT Section 9.104 (G) of the Zoning Ordinance outlines required findings of fact that must be met for the City to grant approval for a Variance. The findings are as follows: The City Council shall make each of the following findings before granting a variance: (a) Because of the particular physical surroundings, or the shape, configuration, topography, or other conditions of the specific parcel of land involved, strict adherence to the provisions of this article would cause practical difficulties in conforming to the zoning ordina nce. The applicant, however, is proposing to use the property in a reasonable manner not permitted by the zoning ordinance. This is correct. Due to the current set up of the building on the property there is no direct access to the west and main entrance to the building that is handicap accessible. The applicant is proposing to use the property in a reasonable manner, but is required to first receive a variance to do so. (b) The conditions upon which the variance is based are unique to the specific parcel of land involved and are generally not applicable to other properties within the same zoning classification. This is correct. The conditions upon which the variance is based are a function of the placement of the building on the property in relation to the property lines. While this might not be a specifically unique situation in the City, this is not an occurrence that happens often on industrially zoned parcels. 32 Item 4. Page 3 (c) The practical difficulties are caused by the provisions of this article and have not been cre ated by any person currently having a legal interest in the property. This is correct. The provisions of the Code require a certain dimensional criteria for parking spaces and drive aisle widths. In order to comply with these requirements, the parking lot had to be shifted towards the property lines. For this reason, the provisions of the Code caused the practical difficulties in this matter. (d) The granting of the variance is in harmony with the general purpose and intent of the Comprehensive Plan. This is correct. The Comprehensive Plan guides this area as industrial. A variance to allow for more parking to accommodate the existing use is consistent with the intent of the Comprehensive Plan. (e) The granting of the variance will not be materially detrimental to the public welfare or materially injurious to the enjoyment, use, development or value of property or improvements in the vicinity. This is correct. The proposed placement of the parking lot is next to a City park and unused property. The use of the parking lot will not be materially detrimental; in fact the granting of this variance will result in newly accessible parking allowing better and more equitable access to the existing building. STAFF RECOMMENDATION Staff recommends that the Planning Commission recommend Resolution 2026-043 to the City Council with the following conditions: 1. The variance applies to the zero ft setback for parking to the north and west and an increased utilization of the zero ft setback on the east, if changes are made to the proposed parking lot a reassessment will need to be made. 2. A Building Permit Application must be submitted prior to construction due to the additional parking lot being a proposed accessible route. 3. Must start construction within one year or the variance will be considered null. RECOMMENDED MOTION(S): MOTION: Move to close the public hearing and waive the reading of draft Resolution No. 2026-043, there being ample copies available to the public. MOTION: Move to recommend that the City Council approve Resolution No. 2026-043, a Variance allowing a 0 ft parking setback for 81 38th Ave NE, Columbia Heights, MN 55421. ATTACHMENT(S): 1.

TO: Columbia Heights Planning and Zoning Location of Variance: 81-38th Ave NE Columbia Heights, MN 55421 Reason for Request: The hardship is for our Handi-Cap clients getting to the front door when the parking lot is on a difference side of the building than the front entrance The location in question is rectangular in shape with a steep hill side and a fence separating my property from the railroad yard on one side and on the North side is a city park. I have very limited parking on the south side of the property. My entrance door faces the lawn area currently, and this does not provide me an area for “Handi-Cap” parking near the entrance door. The company that is using the building provides Tax Preparation Services to the community. Vern and Sandy’s started their MOM and POP company in 1955 and many of the clients have followed them from Johnson Street, Central Ave Lowry Avenue to our final destination here. I am the owner of the building and Vern and Sandy’s/Forsythe is still a family owed company and we would like to accommodate our elderly clients with mobility issues during the winter months. The entrance door of our building used to face California Street until the railroad yard was extended. There is a manhole on this grassy area that add to the complications of upgrading this to a parking lot. There also are 3 wires extending from the telephone poles to the ground to secure the pole from tipping. Larry and Millie Kewatt LLC 37 Item 4.

ITEM: Conditional Use Permit and Final Site Plan Approval for a Car Wash at 47th and Central Ave Presenting Item: Ursula Brandt, City Planner DEPARTMENT: Community Development BY/DATE: Ursula Brandt, City Planner, 7/2/2026 CORE CITY STRATEGIES: (please indicate areas that apply by adding an “X” in front of the selected text below) X Community that Grows with Purpose and Equity _High Quality Public Spaces _Safe, Accessible and Built for Everyone _Engaged, Effective and Forward-Thinking _Resilient and Prosperous Economy _Inclusive and Connected Community CASE NUMBER: 2026-PZ06 APPLICANT: Kimley-Horn & Associates on behalf of Crew Car Wash DEVELOPMENT: Crew Car Wash LOCATION: 47th and Central Ave. Anticipated address of 4707 Central Ave. (PID: 25-30-24-32- 0182) REQUEST: Conditional Use Permit for Car Wash and Site Plan Approval BACKGROUND In 2003 the subject property along with parcels to the north and east were rezoned to Mixed Use District, with the purpose to promote development and redevelopment by allowing the mix of at least two different uses and providing flexibility on bulk requirements. The site was previously occupied by a Kmart shopping Center. Also in 2003, the first site plan was reviewed and approved for a residential portion of the district resulting in the development of Grand Central Commons which consists of Grand Central Flats, Lofts and Townhomes. PLANNING COMMISSION MEETING AGENDA SECTION PUBLIC HEARINGS MEETING DATE JULY 7, 2026 42 Item 5. City of Columbia Heights - Council Letter Page 2 In 2008, the Planning Commission reviewed and approved a commercial development consisting of office and commercial space, along with a parking ramp. In 2018, a Hy -Vee convenience store/gas station was proposed and approved for the site. However, none of the approved site plans for the commercial portion of the mixed-use district have been developed. CURRENT STATUS The applicant met with the City in May of 2026 to review the requirements to locate a Car Wash on the subject property at the corner of 47th Avenue and Central Ave. Staff relayed the requirements, including the Public Hearing and the Sound Study to th e applicant who submitted their proposal for the Crew Car Wash in June of 2026. ZONING ORDINANCE The Zoning Ordinance requires the Planning Commission to hold a Public Hearing on the application for the Conditional Use Permit and submit its recommendation to the City Council. The subject property is zoned MXD (Mixed-Use District) in a planned development that consisted of Grand Central Flats, Lofts and Townhomes. The subject property and the property to the north are the last undeveloped parcels in the Mixed-Use District. The Zoning Ordinance 9.112 specifies that Mixed-Use developments shall contain at least two of the following three land use categories: Residential Uses, Commercial Uses or Institutional Uses. The district currently only has residential uses in the forms of townhomes, condominiums and apartments. Therefore, the last undeveloped parcels must be either commercial or institutional uses. A car wash is a permitted, with a conditional use permit , commercial use in the Zoning Ordinance and is subject to Specific Development Standards 9.107(10) for a car wash. The proposed site plan, as conditioned, shall meet the following specific development standards: (a) Water from the Car Wash shall not drain across any sidewalk or into any public right -of- way; (b) Vacuum facilities shall be located in an enclosed structure or located at least 50 feet from any residential property line to avoid noise impacts. (c) The premises, all adjacent streets, sidewalks and alleys, and all sidewalks and alleys within 100 feet of the use shall be inspected regularly for the purpose of removing litter found thereon. (d) A sound study is required to determine the overall impact upon the surrounding properties and ensure compliance with performance standards and MPCA sound requirements. (e) All new car washes must me located on a minimum of one acre of land. The proposed site plan shows 12 parking spaces and seven (7) stacking spaces in four (4) lanes for a total queue length of twenty-eight (28) total vehicles at the entrance. The proposed plans show all drainage will be handled on site, but it will be conditioned that there shall be no drainage across any sidewalk or into any public right-of-way. The vacuum facilities are located at a distance significantly above the required 50 ft away from residential property. As sound study was submitted and specifies multiple mitigation techniques that will be used to meet the MPCA sound requirements at all sound points (see Performance Standards). The lot is 1.2305 Acres which is above the required 1 acre. 43 Item 5. City of Columbia Heights - Council Letter Page 3 COMPREHENSIVE PLAN The City’s 2040 Comprehensive Plan guides the subject site as “Commercial” as well as the area to the north and Residential (medium and high density respectively) to the east and south. The City of Hilltop lies to the west. A Conditional Use Permit to allow for a Car Wash is consistent with the goals and intent of the Comprehensive Plan. CONDITIONAL USE PERMIT REVIEW Findings of Fact a) The use is one of the conditional uses listed for the zoning district in which the property is located, or is a substantially similar use as determined by the Zoning Administrator. This is correct. A Car Wash is a permitted, with a conditional use permit, commercial use in the Mixed Use District as code states 9.112 (D)(2) “All permitted, conditional, and permitted accessory commercial uses identified in 9.110, Commercial Districts, which are consistent with the comprehensive plan shall be treated as potentially allowable uses withing the Mixed Use District”. b) The use is in harmony with the general purpose and intent of the comprehensive plan. The City’s 2040 Comprehensive Plan guides the subject site as “Commercial” as well as the area to the north and Residential (medium and high density respectively) to the east and south. The City of Hilltop lies to the west. A Conditional Use Permit to allow for a Car Wash is consistent with the goals and intent of the Comprehensive Plan. c) The use will not impose hazards or disturbing influences on neighboring properties. As conditioned, the proposed use will not impose hazards or disturbing influences on neighboring properties as it has addressed sound, stormwater and traffic concerns. d) The use will not substantially diminish the use of property in the immediate vicinity. The site is located on a main throughfare with other commercial uses and multifamily residential. As conditioned, the proposed use is not expected to negatively impact properties in the immediate vicinity. e) The use will be designed, constructed, operated and maintained in a manner that is compatible with the appearance of the existing or intended character of the surrounding area. The proposed car wash is located within the Highway District as designated in the City’s Design Guidelines. As conditioned, the proposed use and site plan will be designed, constructed, operated and maintained in compliance with the design guidelines and therefore the intended character of the surrounding area. f) The use and property upon which the use is located are adequately served by essential public facilities and services. The proposed property is surrounded by fully developed parcels allowing for adequate access to public utilities along with police and fire services. As conditioned the site will have adequate grading and stormwater management on-site. 44 Item 5. City of Columbia Heights - Council Letter Page 4 g) Adequate measures have been or will be taken to minimize traffic congestion on the public streets and to provide for appropriate on-site circulation of traffic. The proposed site design includes 4 lanes of 7 stacking spaces which holds 28 spaces for vehicles waiting to enter the car wash, while the requirement is only 4 stacking spaces . This is an abundance of off-street stacking spaces that will ease the congestion on the street for those entering the space. There is a two-lane drive aisle that leads to and from the vacuums allowing for adequate flow within the site. h) The use will not cause a negative cumulative effect, when considered in conjunction with the cumulative effect of other uses in the immediate vicinity. As conditioned, the proposed car wash use is not expected to have a negative impact on the immediate vicinity as sound, traffic and stormwater have considered and mitigated where applicable. i) The use complies with all other applicable regulations for the district in which it is located. In review of all the application materials and the proposed use being located within a Mixed Use District, which allows for flexibility, it has been determined the proposed use meets all applicable regulations for the district including the Zoning Ordinance and Design Guidelines. SITE PLAN REVIEW 1. Access Two accesses to the site are proposed from the south via 47th Avenue NE, a 60 ft wide public right of way with a road width of 45 ft back of curb to back of curb, through a 40 ft driveway to the east with directional marking for vehicles entering the car wash and directing to the stacking lanes. There is also a 30 ft driveway to the west with directional markings for vehicles exiting the site. 2. Off-Street Parking Supply Requirements. The submitted site plan illustrates a total of 12 off-street parking stalls. The Zoning Ordinance requires two (2) spaces per bay plus four (4) stacking spaces for the one (1) car wash bay including one (1) stacking space at the exit. The Zoning Ordinance also specifies that employee parking is only required when the parking requirements are based on employee counts, as such, the parking requirements for car washes are determined by the number of service bays and stacking spaces, not employee counts. However, the proposed plans indicate four (4) employee designated parking stalls. Appropriately, one off-street parking spaces on the site has been designated as a disability stall (in accordance with the American Disability Act) along with an access aisle striped with “No Parking”. The proposed site plan has more off-street parking than required and has accounted for employee parking needs. 45 Item 5. City of Columbia Heights - Council Letter Page 5 Use Ratio Required Parking Stalls Provided Parking Car Wash Two (2) parking spaces per bay 2 12 (+10) Automobile washing facility– automatic Four (4) stacking spaces per bay with one (1) space at the bay exit 4 stacking spaces at entrance; 1 stacking space at exit. 4 lanes of 7 stacking spaces at entrance; 2 stacking spaces at exit Total 2 spaces 12 spaces (+10) Dimensional Requirements. The proposed off-street parking stalls meet the minimum dimensional requirements of the Ordinance (9 feet in width and 18 feet for stalls which abut a curb) and the provided 24 foot-wide drive aisle is the minimum width required by the Ordinance. Building, Parking, and Vacuum Area Setbacks. The subject Property is zoned MXD (Mixed Use District) Properties with this zoning designation do not have specific setback or dimensional requirements. This is in order to remain flexible for development proposals. Staff believes the proposal does show reasonable setback, height and dimensional information. Car washes have specific development standards requiring that the vacuum facilities must be located in an enclosed structure or located 50 feet from any residential property lines. The vacuums meet the specific development standard and are setback an excess of 50 feet from residential property lines to the south and east. 3. Business Hours It is understood that the car wash is proposing 7AM – 9PM hours of operation, Monday – Sunday, and any vacuum use shall be limited to hours of operation as a condition of approval. 4. Trash Enclosure and Storage The trash enclosure and storage for this site will be part of the building footprint. The indoor storage area will provide a secure, covered enclosure for landscape and lawn maintenance equipment, snow removal equipment, salt storage and materials for upkeep of the exterior vacuums. Both the trash and storage areas are proposed to be on the southeast corner of the building. 5. Fire Access The applicant has provided a fire access plan that demonstrates Columbia Heights’ fire truck specifics and how the trucks will be able to access the site. The routes are within 150 ft of the entrance and allow the fire trucks to be within 150 ft of all sides of the building. 46 Item 5. City of Columbia Heights - Council Letter Page 6 6. Exterior Lighting The applicant has provided a lighting plan, including light fixture specifics and a photometric study. The proposed plan and fixtures satisfy the requirements of 9.106 General Development Standards (K) by keeping the footcandles at or below 0.5 at the residential property lines and 3 for the Central Ave property line as well as proposing fixtures that are downcast. 7. Loading Area The applicant is not proposing any discernable loading areas and the code requirements for off-street loading spaces apply to non-residential uses receiving or distributing materials or merchandise by trucks or similar vehicles and has a gross floor area of 5,000 sq. ft. or more are not applicable to this proposal. The loading area requirements are satisfied per 9.106 General Development Standards (L) (12) as there are no deliveries beyond standard commercial delivery vehicles (UPS, Fed-Ex, and USPS) occurring at the front door. 8. Landscaping – Tree Preservation and Replanting Standards The applicant meets the Tree Preservation and Replanting Standards in 9.106 General Development Standards (M). All trees that exist on the site are considered volunteer weed trees of undesirable and invasive species and are to be removed with the development. The applicant is required to provide one tree for every 50 feet of street frontage and the property has 446 feet of frontage for a total of nine (9) trees, a minimum of four (4) trees per one acre of lot coverage standards for a total of 13 trees proposed. Additionally, the applicant is proposing landscaping containing native plantings and pollinator friendly h abitats for the majority of the trees, shrubs, and grasses used. The City Forester is satisfied with the proposed landscaping plan. As a condition of approval, the applicant is required to provide a letter of credit or other security as acceptable to the City and shall be deposited with the Zoning Administrator, in an amount equal to 100% of the estimated cost of landscaping and/or screening. The letter of credit or other security as acceptable to the City, or portions thereof, shall be forfeited to maintain and/or replace materials for a period of time to include at least two growing seasons. A portion of the letter of credit or other security as acceptable may be released after one growing season as determined by the Zoning Administrator. The property owner shall be responsible for continued maintenance of landscaping and screening materials to remain in compliance with the requirements of this section. Plant materials that show signs of disease or damage shall be promptly removed and replaced within the next planting season. 9. Building Design The proposed site is considered part of the Highway District in the City Design Guidelines and is subject to the standards and requirements of that design district. The proposed site plan demonstrates compliance with the design objectives of the Highway District, the building is set back from the street behind a parking lot. The architectural renderings and site plan, as conditioned, show compliance with building configuration, façade and roof 47 Item 5. City of Columbia Heights - Council Letter Page 7 treatments, building equipment, drive-through facilities, landscaping and parking meet the design guidelines. It is conditioned that all windows and doors must also meet the design guidelines to ensure only 50% of the window are opaque. Any proposed signage will be subject to the design standards as a condition of approval. 10. Performance Standards (Sound) The applicant has provided a Sound Study that analyzed the sound impact that the car wash and vacuum operations will have on the adjacent residential properties and provided mitigations they will use to decrease the sound impact to meet MPCA standards. The applicant is proposing the following mitigation strategies for the vacuums; reduction in the number of vacuums from 10 to 8, placement of the vacuums at the northern extent of the proposed parking lot, vacuum suction will be generated at a single location within the carwash tunnel, vacuum nozzles will be used that have a lower operational noise levels, and an 8 ft by 20 ft brick noise wall will be installed adjacent to the southernmost vacuum unit. The applicant is also proposing the following mitigation strategies to the design of the tunnel; blower units are to be placed inside the tunnel to allow for a 30 ft sound deadening room adjacent to the tunnel exit, (2) 8 ft tall, 10 ft wide roller doors at each end of the tunnel that will be closed whenever the blower units are active. With the use of the mitigation strategies the Car Wash will meet the MPCA noise standards. 11.

Property Description and Background The Project is located in Columbia Heights between Highway 65/Central Ave NE, 47th Ave NE, and Grand Ave NE on a vacant, undeveloped lot. The current property is divided into two parcels; the Applicant seeks to adjust the current lot line for this project via the Minor Subdivision Application process. Parcel B (referred to as “The Property”) will be 1.23-acres with the adjusted lot line and is located in the MXD-Mixed-Use zoning district, which allows car washes as a permitted use. The Project has been designed in accordance with the minimum design standards of the MXD district and is not seeking any variances from the zoning code requirements. The proposed use of the Property is consistent with the forthcoming City of Columbia Heights 2040 future land use update, which will reclassify the site into the GB – Commercial (General Business) zoning district. Site Design The Project consists of a one-story carwash tunnel with approximately 6,200 square feet of total floor area along with a covered entry canopy and self-service vacuums. The Property currently has public sidewalk along Central Ave NE, 47th Ave NE, and Grand Ave NE with no existing curb cuts. The northern parcel, Parcel A, has right-in/right-out access along Central Ave NE to the west. The Central Ave NE reconstruction project will not affect access to the proposed project in Parcel B. The project will create 2 access points (entrance & exit) to the site along 47th Ave NE. 57 Item 5. Page 2 kimley-horn.com 767 Eustis Street, Suite 100, Saint Paul, MN 55114 651 645 4197 Upon entering the Property, customers will enter one of four wash entry lanes where they will either select and pay for their wash from a team member stationed under the canopy or proceed towards an automated scanner if they are an Unlimited Club member. Once payment is complete, an automated gate will open one at a time allowing the customer to proceed towards the wash entrance. If a customer vehicle is rejected from entering the exterior wash, the customer will be directed to exit the wash entry driveway to the west prior to entering the building. On average, customers spend 3-5 minutes from the time they enter the property to the time they depart. After leaving the carwash building, customers will either exit the property or circulate to the west to an available self-service vacuum. The Project will result in an overall increase in impervious surface from the current site development by approximately 65%, since the existing site is a vacant lot with primarily pervious area. Parking and Staffing Parking is provided primarily for Crew Carwash employees, as Customers remain in their vehicle while in the exterior wash tunnel, and only briefly exit their vehicle when choosing to utilize the self- service vacuums. Dedicated parking spaces have been provided for the number of team members expected to be on site at any one time (between 2 and 4 employees). Indoor Trash Enclosure and Storage The trash enclosure and storage for this site will be part of the building footprint. The indoor storage area will provide a secure, covered enclosure for landscape and lawn maintenance equipment, snow removal equipment, salt storage, and materials for upkeep of the exterior vacuums. Snow Storage Snow accumulation will be removed to an off-site location under contract with the snow removal vendor. Nuisance Characteristics The Project is designed to mitigate noise, light, or any other pollution. The vehicle cleaning will occur within the enclosed structures that are acoustically treated to mitigate sound levels produced by the site. Please see the sound study included with this submittal for additional information related to noise level mitigation techniques being installed on the site to meet MPCA sound level requirements. The self-service vacuums are located along the west side of the Property adjacent to Central Ave NE and are only activated when turned on by a customer. It is understood that the zoning code requires open- 58 Item 5. Page 3 kimley-horn.com 767 Eustis Street, Suite 100, Saint Paul, MN 55114 651 645 4197 space vacuum facilities to be at least 50’ from any residential property line to avoid noise impacts; this project meets this criteria. The site lighting will consist of both building and pole-mounted LED light fixtures to fully illuminate the property during opening hours and has been designed to reduce off-site light pollution. Stormwater Management The Project has been designed in accordance with the City of Columbia Heights Surface Water Management Design Standards and the Mississippi Watershed Management Organization (MWMO). The City of Columbia Heights requires that the existing flow rates for the 2, 10, and 100-year 24 hour rainfall events be maintained. In addition, since this project will disturb more than one acre of land, it is required to capture 1.1” of runoff over the net increase in impervious area. Runoff from the proposed impervious areas will be routed to new underground ADS MC-7200 chambers to satisfy the rate control, volume control, and water quality requirements and will provide a single point to collect sediment, oil, and floating debris prior to stormwater runoff flowing offsite into the municipal storm sewer system. Since the underground BMP will utilize infiltration, the volume control requirement shall be met to also satisfy the water quality requirement. Wash Water Reclamation A state-of-the-art wash water recapture system will be installed to clean and recycle the water used for the car wash process. This system both contributes to responsible use and re-use of water on the project, and ensure that any downstream impacts of increased sanitary wastewater flow is minimized.

Crew Carwash Columbia Heights, MN - Sound Study May 2026 - Page 1 kimley-horn.com 767 North Eustis Street, Suite 100, Saint Paul, MN 55114 651 645 4197 June 2026 Ursula Brandt City Planner City of Columbia Heights 3989 Central Avenue NE Columbia Heights, MN 55421 Subject: Crew Carwash – Sound Study 47th Avenue, Columbia Heights, MN 55421 Executive Summary This sound study is for the proposed Crew Carwash facility to be constructed on approximately 1.23 acres in Columbia Heights, Minnesota (the project). The project will be located northeast of the Central Avenue and 47th Avenue Northeast intersection. The original project layout included 16 blower units within the carwash building and 10 outdoor vacuum generators which represent the primary noise sources evaluated. The existing noise environment is characterized by traffic, commercial activity, and other typical community noise sources. A total of 17 noise-sensitive receptors were identified as close as 40 feet from the project site, including residential buildings, a hotel, a playground, and restaurant patios. SoundPLAN was used to model normal project operations. Based on the modeling results, 13 of the 17 receptors would exceed the Minnesota Pollution Control Agency (MPCA) daytime L50 noise thresholds without noise mitigation. To comply with MPCA thresholds, Kimley-Horn recommends Crew Carwash reconfigure and reduce vacuum units, add a noise wall between the vacuum units and sensitive receptors to the south, and install a sound deadening room at the outlet of the carwash tunnel. Project Description The carwash project will be constructed on approximately 1.23 acres of undeveloped land in the city of Columbia Heights, Minnesota (the project site), see Figure 1. The project site is directly northeast of the Central Avenue intersection with 47th Avenue Northeast. Central Avenue borders the project to the west, 47th Avenue borders the project to the south, and Grand Avenue Northeast borders the project site to the east. The original site plan included 10 vacuum generators and 16 blowers, which would be the main sources of noise. 85 Item 5.

Existing noise sources in the vicinity generally include vehicular traffic on adjacent and nearby roadways (including Central Avenue Northeast/Trunk Highway 65), local transit operations, commercial activities, and occasional emergency vehicle sirens. Additional intermittent noise sources typical of urban environments, such as nearby construction activity, mechanical equipment, and general community activity, also contribute to the existing noise environment. As a result, background noise levels in the project area are characteristic of an urban setting where periods of elevated sound levels occur regularly and fluctuate throughout the day and night depending on traffic volumes and surrounding land uses Adjacent Noise Receptors Kimley-Horn identified 17 sensitive noise receptors near the project site. Receptors to the west are as close as 200 feet from the project site and include 3 apartment buildings, 1 hotel, and 1 restaurant patio. Receptors to the south are as close as 65 feet from the project site and include 3 apartment buildings and one single-family residence. Receptors to the east are as close as 40 feet from the project site and include 1 apartment building, 1 playground, and 1 multi-family residence. There is 1 receptor 100 feet north of the project site which is a restaurant patio. At receptor locations 12 – 15, there are 3 stories of apartment balconies facing the project at approximately 10, 20, and 30 feet above ground level. Characteristics of Noise Noise is generally defined as unwanted sound. It is emitted from many natural and man-made sources. Sound pressure levels are usually measured and expressed in decibels (dB). The decibel scale is logarithmic and expresses the ratio of the sound pressure unit being measured to a standard reference level. Most sounds occurring in the environment do not consist of a single frequency, but rather a broad band of differing frequencies. The intensities of each frequency add together to generate sound. Because the human ear does not respond to all frequencies equally, the method commonly used to quantify environmental noise consists of evaluating all of the frequencies of a sound according to a weighting system. It has been found that the A-weighted decibel (dBA) filter on a sound level meter, which includes circuits to differentially measure selected audible frequencies, best approximates the frequency response of the human ear. L10 is also a sound pressure metric that represents the sound pressure level, in dBA, exceeded ten percent of the time during a one-hour survey. Similarly, L50 represents the sound pressure level, in dBA, exceeded 50 percent of the time during a one-hour survey. The degree of disturbance from exposure to unwanted sound – noise – depends upon three factors: 1. The amount, nature, and duration of the intruding noise 2. The relationship between the intruding noise and the existing sound environment; and 3. The situation in which the disturbing noise is heard 87 Item 5. Crew Carwash Columbia Heights, MN - Sound Study May 2026 - Page 4 kimley-horn.com 767 North Eustis Street, Suite 100, Saint Paul, MN 55114 651 645 4197 In considering the first of these factors, it is important to note that individuals have varying sensitivity to noise. Loud noises bother some people more than other people, and some individuals become increasingly upset if an unwanted noise persists. The time patterns and durations of noise(s) also affect perception as to whether or not it is offensive. For example, noises that occur during nighttime (sleeping) hours are typically considered to be more offensive than the same noises in the daytime. With regard to the second factor, individuals tend to judge the annoyance of an unwanted noise in terms of its relationship to noise from other sources (background noise). A car horn blowing at night when background noise levels are low would generally be more objectionable than one blowing in the afternoon when background noise levels are typically higher. The response to noise stimulus is analogous to the response to turning on an interior light. During the daytime an illuminated bulb simply adds to the ambient light, but when eyes are conditioned to the dark of night, a suddenly illuminated bulb can be temporarily blinding. The third factor – situational noise – is related to the interference of noise with activities of individuals. In a 60 dBA environment such as is commonly found in a large business office, normal conversation would be possible, while sleep might be difficult. Loud noises may easily interrupt activities that require a quiet setting for greater mental concentration or rest; however, the same loud noises may not interrupt activities requiring less mental focus or tranquility. As shown in Figure 2, most individuals are exposed to fairly high noise levels from many sources on a regular basis. To perceive sounds of greatly varying pressure levels, human hearing has a non-linear sensitivity to sound pressure exposure. Doubling the sound pressure results in a three decibel change in the noise level; however, variations of three dBA or less are commonly considered “barely perceptible” to normal human hearing. A five decibel dBA change is more readily noticeable. A ten- fold increase in the sound pressure level correlates to a ten decibel [dBA] noise level increase; however, it is judged by most people as only sounding “twice as loud”. Over time, individuals tend to accept the noises that intrude into their lives on a regular basis. However, exposure to prolonged and/or extremely loud noise(s) can prevent use of exterior and interior spaces and has been theorized to pose health risks. 88 Item 5.

This rule establishes the noise standards in Table 1 based on Noise Area Classification (NAC). A NAC is based on the land use of the location where a person may hear noise. Noise from the project will be regulated according to the NAC of surrounding receptors.

This sound study is being prepared in accordance with this requirement. According to Chapter 30, Article II, Section 30-21 (a) of the Anoka County Code of Ordinances, “…between the hours of 10:00 p.m. and 7:00 a.m…No person shall engage in or permit heavy machinery activity involving the use of any kind of electric, diesel or gas-powered machine or other power.” The project will not operate outside of 7:00 a.m. to 10:00 p.m.. Noise Measurements Kimley-Horn used a Larson Davis SoundExpert Lxt Sound Level Meter (Serial No. 0005586) during a field visit to the West Saint Paul Crew Carwash on April 29, 2026. During this field visit, the noise analyst measured sound levels of typical equipment operations. The equipment at the West Saint Paul location is anticipated to have similar sound levels to equipment proposed for the project site. Three 1-minute measurements were conducted for a pair of operating vacuum generators in the parking lot at distances of 5, 10, and 20 feet from the nearest generator. Similarly, three 1-minute measurements were conducted for the blowers in the carwash building at distances of 5, 10, and 20 90 Item 5.

This program computes predicted sound levels at noise-sensitive areas through a series of adjustments to reference sound levels. SoundPLAN also accounts for topography, groundcover type, and intervening structures. Sound levels generated from the on-site vacuum generators and the car wash blowers are anticipated to be the main sources of sound from the project. It should be noted that noise from surrounding roadways was not modeled in this analysis, although Central Avenue and other nearby roadways are anticipated to contribute to the ambient noise environment throughout the entire day. Vacuum Generators Vacuum generator equipment can generate steady, unvarying sound during daytime operation that may create issues when located near noise-sensitive areas. According to the original site layout, 10 vacuum generators were going to be located along the western boundary of the project site. Based on the field measurements discussed above, the modeled vacuum generators were calibrated to have an overall noise level one dBA louder than measurement data at 10 feet from the source. The modeled sound power of each vacuum generator is included in Table 3. Table 3.

In the current site layout, the tunnel exit near the blowers will be located on the southern façade of the building and the tunnel entrance, opposite the blowers, will be located on the northern façade. There are 16 blower units modeled in the standard configuration for Crew Carwash locations. Based on the field measurements discussed above, the modeled blowers were calibrated to have an overall noise level one dBA louder than measurement data at 20 feet from the tunnel exit. The modeled sound power of each blower is included in Table 4. Table 4.

The tunnel entrance was modeled as 14 feet wide and 10 feet tall, a partition wall with a 14-foot-wide and 10-foot-tall opening was modeled 26 feet into the tunnel, a second partition wall with a 10-foot-wide and 8-foot-tall opening was modeled approximately 108 feet into the tunnel, the tunnel exit was also modeled as 10 feet wide and 8 feet tall. Results The project would only operate during daytime hours (7 a.mm to 10 p.m.) so results were compared to the MPCA daytime L50 thresholds. The model predicts that 13 of the 17 receptors would not comply with MPCA noise standards without mitigation. See Table 2 for anticipated unmitigated noise levels at noise sensitive receptors. See for a map of unmitigated noise levels surrounding the project site under normal operations. Table 5.

Further, a vacuum nozzle with lower operational noise levels is recommended for this location. Based on coordination with Crew Carwash and the vacuum manufacturer, Kimley-Horn assumed a noise level of 68.1 dBA at 30 feet from the quieter vacuum unit. The modeled sound power at each vacuum unit was calibrated to reflect this quieter noise level but maintain the same spectral spread across frequencies as the field measurements, see Table 6. Table 6. Modeled Sound Power of Quieter Vacuum Nozzle 31 Hz 63 Hz 125 Hz 250 Hz 500 Hz 1 kHZ 2 kHZ 4 kHz 8 kHz Overall Sound Power (dBA) 77.6 84.2 88.1 90.6 94.2 88.1 88.5 85.7 84.5 95.7 Kimley-Horn also recommends that the number of vacuum units be reduced from 10 to 8 to further reduce noise levels at nearby receptors. Additionally, it is recommended the remaining 8 units are moved to the northern extent of the proposed parking lot and that a 20-foot-long, 8-foot-high brick noise wall be installed adjacent to the southernmost vacuum unit. Carwash Tunnel Layout It is recommended that the 16 blower units and other applicable carwash equipment are moved within the tunnel to allow for a 30-foot-long sound deadening room adjacent to the tunnel exit. Kimley-Horn recommends installing two (2) 8-foot tall, 10-foot-wide aluminum roller doors at each end of the carwash tunnel. For noise from the blower units to be adequately shielded, it is recommended that one of these aluminum roller doors always remain closed while the blower units are operational. In addition to adding a sound-deadening room, Kimley-Horn recommends lining all walls of the carwash tunnel, including the ceiling, with AcoustiBlok 5-inch Quietfiber, see Appendix A for product absorption data. To ensure this sound absorbing treatment does not deteriorate and lose efficacy, Acoustiblok recommends installing their waterproofing treatment to the Quietfiber if it will be frequently exposed to wet conditions. The original model was updated to reflect the recommended changes to the vacuum equipment, site layout, and interior of the carwash tunnel. The updated model predicts that all receptors would comply 95 Item 5.

The city of Columbia Heights enforces MPCA noise standards; therefore, project noise levels must comply with the daytime L50 noise thresholds. 13 of the 17 modeled noise-sensitive receptors adjacent to the project site would exceed the daytime L50 noise thresholds without noise abatement. Kimley-Horn has recommended alterations to vacuum equipment, installation of a noise wall, and addition of a sound deadening room to the carwash tunnel. Following coordination with Crew Carwash, Kimley-Horn has implemented these mitigation measures into the current site plans. These recommendations resulted in modeled noise levels that comply with MPCA noise standards. Kimley-Horn encourages Crew Carwash to continue consultation with noise control engineers to ensure the final project design remains compliant with MPCA noise standards. 98 Item 5. Appendix A.

Therefore, the EDA has requested that the Planning Commission review the acquisition of 4217 Central Ave NE, Columbia Heights, MN 55421 (the “Subject Property”) to determine if its acquisition conforms to the Comprehensive Plan of the City. COMPREHENSIVE PLAN: The EDA has a long-standing practice of acquiring blighted single-family homes to facilitate scattered site redevelopment, and the proposed acquisition of the Subject Property responds to several goals and policies adopted in the Comprehensive Plan. Specifically, in Chapter 3: Land Use, and Chapter 4: Housing. Below are the specific goals and policies from the Comprehensive Plan that directly and indirectly correlate to the conformity of the proposed acquisition. Land Use and Redevelopment (chapter 3) Goal: Provide mechanisms for successful redevelopment of vacant lands and targeted areas within the community. 106 Item 6. Page 2 1. Encourage infill development that demonstrates compatibility with existing neighborhood characteristics in terms of quality, design, building height, placement, scale, and architectural quality. Goal: Strengthen the identity and image of the community as a desirable place to live, work, and play. 1. Enhance the physical appearance of the community through clean-up initiatives, redevelopment opportunities, and housing renovation programs. STAFF RECOMMENDATION Staff Recommends the adoption of Resolution 2026-PZ01, as it meets the goals of the Comprehensive Plan and supports Core City Strategies. RECOMMENDED MOTION(S): MOTION: Move to waive the reading of Resolution 2026-PZ01, there being ample copies available to the public. MOTION: Move to adopt Resolution 2026-PZ01, a resolution finding that the acquisition of certain land for redevelopment purposes by the Columbia Heights Economic Development Authority is consistent with the City of Columbia Heights’ Comprehensive Plan.
