Item 6FCase No. ZA20-0051 S T A F F R E P O R T November 10, 2020 CASE NO: ZA20-0051 PROJECT: Specific Use Permit for a Residential Solar Energy System EXECUTIVE SUMMARY: MYO Power , on behalf of the owner Remana Venigalla, is requesting approval of a Specific Use Permit for a Residential Solar Energy System on property described as Lot 6, Block 7, Carillon Phase 4C Addition, City of Southlake, Tarrant County, Texas and located at 821 Lake Carillon Lane, Southlake, Texas. Current Zoning: “EZC” Employment Center District. SPIN Neighborhood #3. DETAILS: The applicant is requesting approval to install a residential solar energy system to be located on south roof of the house. The proposed solar array for the house consists of 22 solar energy panels (each panel is approximately 39.33” by 65.51”) totaling approximately 393.6 square feet and generally oriented southwest. The proposed system produces 6.82 kW. Additional information may be found in the specific use permit plans. For the November 17, 2020 City Counc il meeting, the applicant has provided the adjacent property owners signatures as requested by the Planning and Zoning Commission and provided photographs of the proposed solar panels on existing residential roofs.

(ZA08-031) May 5, 2009; A preliminary plat showing four hundred twenty-three total lots was approved. (ZA09-010) September 27, 2013; The Planning and Zoning Commission approved a final plat for Carillon Phase 4C. (ZA13-003) TRANSPORTATION ASSESSMENT: This request does not affect traffic on or around the property. TREE PRESERVATION: The proposed solar panels are to be installed on the side roof of the house; no trees will be affected by the request. PLANNING AND ZONING COMMISSION: November 5, 2020; Approved (4-2) subject to the Staff Report dated October 30, 2020; further subject to the Specific Use Permit Review Summary No. 2 dated October 16, 2020; and noting the comments made earlier and the applicant’s agreement to bring additional information to the City Council meeting. Commissioner Springer dissented and did not like the location on the roof and an approval may set a precedent for future cases. Commissioner Phalen dissented and did not like the location with no tree coverage and landscaping with a tall building. STAFF COMMENTS: Staff review may be found in the Specific Use Permit Summary No. 2 dated October 16, 2020.
