No. 483 Section 8.01(A) requiring that all lots must front on a public or private street. Common Access Easements will provide access to all lots.  Stacking Depth – The required stacking depth is 75 feet. The applicant is requesting a stacking depth of ± 41 feet. (Driveway Ord. No. 634, Section 5.1)  Driveway Spacing – The required driveway spacing on S. Kimball Ave. is 250 feet. The applicant is requesting a driveway spacing of 106 feet. (Driveway Ord.

PROPERTY SITUATION: 165 S. Kimball Ave. LEGAL DESCRIPTION: Tract 2, George W. Main Survey, Abstract No. 1098 FUTURE LAND USE: Mixed Use CURRENT ZONING: “S-P-1” Detailed Site Plan District HISTORY: - The property was annexed into the City in 1956 and given the “AG” – Agricultural District Zoning Designation. - A Zoning Change and Site Plan (ZA08-050) for CySolutions from “AG” Agricultural District to “S-P-1” Detailed Site Plan District to develop three office buildings on approximately 1.68 acres was approved by City Council on September 16, 2008. TRANSPORTATION ASSESSMENT: Master Thoroughfare Plan The Master Thoroughfare Plan shows S. Kimball Ave. to be a four-lane divided arterial with 88 feet of right-of-way. Right-of-way must be dedicated for this road in accordance with the Master Thoroughfare Plan. The required dedication is 44’ from centerline. PATHWAYS MASTER PLAN: A six-foot sidewalk exists along the west side of S. Kimball Avenue. A five-foot sidewalk is required for the proposed development and shown on the approved Site Plan. WATER & SEWER: There is a 12 inch diameter waterline located on the west side of Kimball Ave to serve this development. There is an 8 inch diameter sewer line located along the east side of Kimball Ave on the south west portion of this property to serve this development. DRAINAGE ANALYSIS: The drainage from this development is generally to the west and south. There is no existing storm sewer system available nearby this property. TREE PRESERVATION: A Tree Preservation Plan was approved with the S-P-1 zoning for CySolutions (ZA08-050). Approximately 48% of the site has existing tree cover. Approximately 43% of the existing tree cover area is proposed to be preserved. The preservation areas are relatively evenly spread through the site, having some preservation along the frontage, center, side yards and corners of the property. The existing trees in the southwest corner of the development are shown as “borderline” preservation trees due to being within a drainage detention area. If a flume is provided to carry the everyday irrigation run-off, this may prevent saturation of the root zones and may help ensure their preservation if they are Case No. Attachment A ZA15-068 Page 1 not adversely affected by grading.

Tree Conservation/Landscape Review E-mail: kmartin@ci.southlake.tx.us Keith Martin Landscape Administrator Phone: (817) 748-8229 Tree Preservation Comments * Approximately 48% of the site has existing tree cover. Approximately 43% of the existing tree cover area is shown to be preserved on the Tree Conservation Plan that was approved with the S-P-1 Zoning Change and Site Plan for CySolutions Office Complex (ZA08-050). The preservation areas are relatively evenly spread through the site having some preservation along the frontage, center, side yards and corners of the property. * Some of the existing trees in the southwest corner of the development are shown as “borderline” preservation trees due to being within a drainage detention area. If a flume is provided to carry the everyday irrigation run-off this may prevent saturation of the root zones and may help insure their preservation, if they are not adversely affected by grading. * Please be aware that all existing trees shown to be preserved on the City Council approved Tree Conservation Plan must be preserved and protected during all phases and construction of the development. Alteration or removal of any of the existing trees shown to be preserved on the approved Tree Conservation Plan is a violation of the Tree Preservation Ordinance and the zoning as approved by the Southlake City Council. Please ensure that the layout of all structures, easements, utilities, structures grading, and any other structure proposed to be constructed do not conflict with existing trees intended to be preserved.
