Item 6B13 SOUTHLAKE CITY OF Department of Planning & Development Services STAFF REPORT July 14, 2010 CASE NO: ZA10 -040 PROJECT: Site Plan for Carroll Elementary School Improvements EXECUTIVE SUMMARY: On behalf of Carroll Independent School District, Hart, Gaugler and Associates, Inc. is requesting approval of a site plan for improvements to Carroll Elementary School on approximately 25.23 acres located at 1705 W. Continental Blvd. SPIN # 10. REQUEST DETAILS: An approximately 8,080 square foot addition to the existing building would consist of additional library, administration, security, gym and cafeteria space. The existing fire lane will be relocated and 36 parking spaces will be demolished. The existing parking lot will be extended to the north and 37 parking spaces will be added. The drop -off lanes will be reconfigured to allow for the building expansion. A turn - around loop will be added for the bus drop off on the east side of the building. The Planning and Zoning Commission approved the case 4 -0 on July 8, 2010, granting the requested variances, noting the applicant's willingness to look at using brick over the storefront instead of aluminum panels and noting the applicant's willingness to review the drainage outfall to the east. The applicant will address using aluminum panels over the storefront and present an exhibit that shows proposed improvements to the drainage outfall at the Council meeting. VARIANCES REQUESTED: 1. Variance to Zoning Ord. No. 480, Section 43.13.a.4, requiring horizontal and vertical articulation for buildings adjacent to residential properties. The applicant is proposing articulation as shown on the elevations and site plan. 2. Variance to Zoning Ord. No. 480, Section 42 requiring bufferyards along the east and west property lines adjacent to residential properties. The applicant is requesting a waiver of the bufferyard requirements due to the fact that irrigation would disturb the root zones of existing trees and vegetation. 3. Variance to Zoning Ord. No. 480, Section 39.6, requiring an eight foot (8) solid fence adjacent to residential properties. The applicant is requesting a waiver of this requirement due to the screening provided by the existing trees and vegetation.

Thompson Survey, Abstract No. 1541 LAND USE CATEGORY: Public /Semi - Public CURRENT ZONING: "CS" Community Service District HISTORY: -A site plan for a 600 square foot building addition to the kitchen area was approved by City Council on March 5, 2002. CITIZEN INPUT/ BOARD REVIEW: A SPIN meeting was held May 24, 2010. The meeting report is attached (Attachment D). PATHWAYS MASTER PLAN: A 6' sidewalk exists along W. Continental Blvd. The 2025 Pathways Plan shows an 8' multi -use trail planned along the eastern and southern property boundaries. However, the impact of the expansion is not roughly proportional to the addition of the multi -use trail, so construction of the trail is not required at this time. TRANSPORTATION ASSESSMENT: The existing school site has access to W. Continental Blvd. The City's Southlake 2025 Mobility and Master Thoroughfare Plan designates W. Continental Blvd. as a two -lane undivided collector with 84 feet of right -of -way. TREE PRESERVATION: One (1) existing tree (12" Live Oak) is proposed to be removed for the proposed construction. DRAINAGE COMMENTS: The proposed drainage area map shows no changes to the existing drainage areas. PLANNING AND ZONING COMMISSION ACTION: July 8, 2010, Approved (4 -0) noting the applicant's willingness to review the drainage outfall to the east, noting the applicant's willingness to look at using brick instead of aluminum over the store front glass, granting the requested variances, and subject to Revised Site Plan Review Summary No. 2, dated July 7, 2010.

Roadway /Access: The building addition will be in the front (west side) of the existing building. The existing fire lane will be relocated and 36 parking spaces will be demolished. The existing parking lot will be extended to the north and 37 parking spaces will be added. The drop -off lanes will be reconfigured to allow for the building expansion. A turn- around loop will be added for the bus drop -off on the east side of the building. Storm Sewer The onsite drainage will consist of grate inlets, and area drains. We anticipate the use of RCP for larger diameter pipes and HDPE for smaller diameter pipes. The storm drainage improvements relate to some slow draining areas adjacent to the building foundations that are causing some movement of the floor slab inside the school. We will be lowering some existing area drains on the west side of the building and physically tying in the existing roof drain downspouts to the storm drain system. On the east side, we will be adding a couple of area drains and will physically tie in the existing roof drain downspouts to the new system. The new pipe will outfall east of the existing driveway. Electric, Telephone, and Gas Franchise utilities exist on -site. Landscape: Entire campus interior landscape requirements will be compliant with the current ordinance. Variance Requests • Facade Articulation: On all facades, the horizontal and vertical articulation will be as shown on the Site Plan and the Building Elevations. • Bufferyards: Bufferyards are required along the property boundary where the property abuts a residential zoned property. Due to the existing tree cover and vegetation, bufferyards will not be provided in those areas. Adding shrubs and accent plants would require irrigation and will disturb the root zones of the existing trees. 12801 N.
