Home My WebLink AboutItem 5City of Lakeville Planning Department Memorandum To: Planning Commission From: Monica Waite, Planning & Zoning Specialist Date: January 31, 2020 Subject: Packet Material for the February 6, 2020 Planning Commission Meeting Agenda Item: Lake Marion Elementary School Conditional Use Permit Amendment Application Action Deadline: February 20, 2020 INTRODUCTION Representatives of ISD #194 are requesting an amendment to CUP #89-05 to allow an expansion to the Lake Marion Elementary School building, located at 19875 Dodd Boulevard. The site contains the existing Lake Marion Elementary School, a parking lot, a lot for buses, baseball fields and playgrounds. The proposed addition will include 15,420 square feet on the southeast side of the existing 77,600 square foot building. The project will also include parking lot and driveway improvements to address street access and traffic flow. The existing school was constructed in 1989. The subject property is zoned RS-2, Single Family Residential District. Section 11-51-7D of the Zoning Ordinance allows public elementary schools in the RS-2 District by conditional use permit. EXHIBITS A. Aerial Photo Map B. Location/Zoning Map C. Topographic Survey D. Grading, Drainage, and Erosion Control Plan (4 pages) E. Site Access Modifications F. Utility Plan 2 G. Landscape Plan (4 pages) H. Floor Plan I. Exterior Elevations PLANNING ANALYSIS The proposed 15,420 square foot expansion to the southeast side of the existing elementary school building will be over an existing grassy area facing Dodd Boulevard. The project includes the construction of classrooms and bathrooms off an extension of the existing building. The proposed expansion was reviewed for conformance with Zoning Ordinance performance standards as follows: Surrounding Land Uses and Zoning North –Lakeville North High School (P/OS) South – Attached Townhomes (RM-1) East – Dodd Boulevard and Office Buildings (C-3) West – Ames Arena (P/OS) Building Setbacks. The existing and proposed buildings meet all setback requirements of the RS-2 District: Front – 30 feet Side – 15 feet Rear – 30 feet The proposed building addition will have the following setbacks from the closest property line: Front (east) –115.7 feet Side (south) – 52.1 feet Building Height. The building addition is single story and 14 feet in height and will not exceed the maximum building height of 35 feet allowed in the RS-2 District. Access and Circulation. The School District and Elementary School representatives raised concerns to City staff regarding safety entering and exiting the school property and vehicle queuing along Dodd Boulevard. The applicant proposed a second access off Dodd Boulevard to serve as a right only exit. Dakota County reviewed this request and it was denied due to minimum access spacing requirements and the recorded plat requirement that the property would be subject to one access off Dodd Boulevard. The applicant proposes a redesign and expansion of the parking lot and existing access off Dodd Boulevard. This would include a two lane entrance on site to separate bus and vehicle traffic, and a right only exit, with an expanded drop off lane and parking lot improvements. City staff proposed a more comprehensive circulation plan in conjunction with changes at Ames Arena to the west of the school. This 3 would include a single lane drive connection to the Ames Arena parking lot, creating a separate entrance for the school via Ipava Avenue. City staff presented this recommendation to remove conflicts between entering/exiting vehicles during pick up and drop off times and to reduce vehicle queues along Dodd Boulevard. The School District chose not to explore the option. Parking. According to ISD 194, the current enrollment is 700 students and the projected enrollment is 900 students. The Zoning Ordinance requires one parking space per seven students, which equals 129 parking spaces to accommodate the projected enrollment. The property currently has 105 on-site parking spaces, with the proposed addition of 80 on-site parking spaces, for a total of 185 on-site parking spaces. The applicant also proposes the addition of 18 stadium area parking spaces to be used as overflow parking, for a total of 86 off- site shared parking spaces. This parking lot is to be shared with Lakeville North High School. All on and off site parking shall be constructed to meet the requirements of the Zoning Ordinance. The total amount of proposed available parking exceeds Zoning Ordinance requirements. Trails and Sidewalks. The existing pathways will be reconfigured and extended to accommodate the addition and parking lot improvements. Building Elevations and Exterior Building Materials. The proposed building addition will be sided with brick to match the existing building. Landscaping. Dodd Boulevard is identified as a roadway corridor listed in the Corridor and Gateway Design Study as adopted in the Zoning Ordinance, so additional screening from developments is required in the area that abuts a road like Dodd Boulevard. Institutional uses require a continuous opaque barrier along the off street parking area perimeter abutting public right-of-way and residentially zoned properties. Additionally, the building addition abuts a residential district to the south, which requires adequate screening from the residential properties. No landscape material shall be located in the Highway & Utility easement on the east property line or within the public right-of-way. All proposed landscape material shall comply with Zoning Ordinance requirements. A final landscape plan shall be submitted prior to City Council action. Signs. There is no new signage proposed with the addition. Mechanical Equipment. There is additional mechanical equipment proposed with the building addition that will be located on the roof and screened in compliance with Zoning Ordinance requirements. Trash Enclosure. There is an existing, compliant trash enclosure on the north side of the building. 4 Lighting. Exterior lighting is proposed to be increased for the site. Exterior lighting must comply with Section 11-16-17 of the Zoning Ordinance. Detailed fixture and photometric plans must be submitted with the Building Permit application for the proposed addition. Engineering Review. The Engineering Department has reviewed the plans and prepared a memorandum dated January 31, 2020, which references the need for a financial security in the amount of $259,997.75 prior to the issuance of a Building Permit for the addition. RECOMMENDATION Planning Department staff recommends approval of the Lake Marion Elementary School conditional use permit amendment located at 19875 Dodd Boulevard subject to the following stipulations: 1. The site plan and building addition shall be developed in accordance with the plans approved by the City Council. 2. A building permit is required prior to commencing construction of the building addition. 3. The proposed building addition shall be sided with brick to match the existing building. All building materials shall meet the requirements for an institutional use in the RS-2 District. 4. Lighting must comply with Section 11-16-17 of the Zoning Ordinance. Detailed fixture and photometric plans must be submitted with the Building Permit application for the proposed addition. 5. The building addition is subject to review by the Fire Marshal. 6. All off street parking shall be constructed to meet the requirements of the Lakeville City Code. A revised site plan shall be submitted prior to City Council Action. 7. A final landscape plan shall be submitted prior to City Council Action. The landscape plan shall comply with requirements of the Lakeville City Code. 8. A financial security in the amount of $259,997.75 shall be provided as security for the site improvement performance agreement prior to the issuance of a Building Permit as described in the Engineering Department memorandum dated January 31, 2020. ± Lake Ma rion Elementar y S cho ol 202ND ST Lake Marion Elem.

Parking lot improvements include additional parking stalls and access improvements. Existing access has one lane of traffic entering the site and two lanes of traffic with full access exiting the site. The proposed access has one lane of traffic entering the site then widens to allow for an additional lane for car stacking, the proposed exit restricts turning movement to right-turn only. The applicant is proposing additional stalls on the private drive to the parcel to the north. The parking lot and site access improvements were discussed with City and County Transportation Staff. The School District and Elementary School representatives raised concerns to City staff regarding safety entering and exiting the school property and vehicle queuing along Dodd Boulevard. Alternative accesses were considered and discussed with City and County staff. To address the District’s concerns, City staff recommended construction of a single lane drive connection to the Ames Arena parking lot west of the school, creating a separate entrance for the school via Ipava Avenue. City staff presented this recommendation to remove conflicts between entering/exiting vehicles during pick up and drop off times and to reduce vehicle queues along Dodd Boulevard. The School District chose not to explore the option.
