Bailey Survey, Abstract No. 97, City of Southlake, Tarrant County, Texas and located at 803 W. Southlake Blvd., Southlake, Texas. Current Zoning: "AG" Agricultural District. Proposed Zoning: "S-P-1" Detailed Site Plan District. SPIN Neighborhood #10. DETAILS: The property is generally located west of the southwest intersection of W. Southlake Blvd. and Timber Lake Place. The purpose of this request is to seek approval of a Zoning Change and Site Plan for the construction of an approximately 9,913 7,308 square foot single-story office building. The proposed “S-P-1” Detailed Site Plan District allows for all “O- 1” Office District uses with exception to medical office uses which includes but is not limited to chiropractors, dentists, optometrists, physicians, podiatrists, psychiatrists and psychologists. The property is currently vacant and unplatted with an “AG” Agricultural District zoning. An appropriate plat that conforms to the underlying zoning district will be required to be processed, approved and recorded prior to the issuance of any building permits for the proposed project. Due to the location of the property, it is subject to FM 1709 Corridor Overlay Zone requirements as well as Residential Adjacency standards. The applicant is requesting an “S-P-1” Detailed Site Plan District zoning to accommodate specific regulations for the proposed building setbacks, parking, driveway access, tree preservation and landscaping. The current Future Comprehensive Land Use Plan designation for this property is Medium Density Residential. The applicant has filed a request to amend the Comprehensive Land Use Plan Map to maintain the Medium Density Residential designation, however, allowing a site-specific office commercial use under City case CP20-0001 to accommodate the associated zoning change and site plan request. On February 20, 2020, the Planning & Zoning Commission reviewed and discussed the original application that proposed an approximately 9,913 square foot building. The Commission recommended the applicant consider reducing the size of the proposed building in an effort to better fit the subject lot, save as many trees as possible and reduce the number of variances. The applicant requested to table their item and the Commission unanimously approved tabling until March 19, 2020. On March 17, 2020, the City Council canceled the March 19, 2020 Case No. ZA19-0025 Planning & Zoning Commission meeting. The applicant has submitted revised plans for consideration which include the following: the building size has been reduced from 9,913 s.f. to 7,308 s.f.; the impervious coverage has decreased from 75% to 57.9%; the building setback line increased along the south and east property boundaries from 15 ft. to 25 ft.; the south setback for the trash receptacle increased from 10 ft. to 25 ft.; tree preservation increased from 13% to 36%; and, they replaced a majority of the previously proposed stucco building material with smooth stone. Also, the previously requested variances for Driveway Stacking and Interior Landscaping have been removed with the updated plan set. The following is the updated site data summary as proposed: Site Data Summary Component Existing Proposed S-P-1 Zoning AG S-P-1 with limited O-1 uses Land Use Medium Density Residential Medium Density Residential allowing site specific Office Commercial uses Floor Area vacant 9,913 7,308 sf Gross Lot Area 37,418 s.f.

Southlake Blvd. LEGAL DESCRIPTION: Tract 1, J.T. Bailey Survey, Abstract No. 97 LAND USE CATEGORY: Medium Density Residential CURRENT ZONING: “AG” Agricultural District PROPOSED ZONING: “S-P-1” Detailed Site Plan District HISTORY: -The property was annexed in 1956. -The property is currently unplatted and vacant. Prior to demolition, there was a structure that was used for taxidermy. SOUTHLAKE 2035 PLAN: Consolidated Future Land Use Plan The underlying land use designation is Medium Density Residential. The purpose of the Medium Density Residential land use category is to promote a neighborhood setting primarily comprised of single-family detached houses. The Medium Density Residential category is suitable for any single-family detached residential development. Other suitable activities are those permitted in the Public Parks/Open Space and Public/Semi- Public categories. The proposed zoning change and site plan is not consistent with this designation. The applicant has filed an application (CP20-0001) to amend the land use plan map requesting to maintain the Medium Density Residential land use designation and allow a site-specific Office Commercial use to accommodate the proposed project. Mobility and Master Thoroughfare Plan The Master Thoroughfare Plan recommends W. Southlake Blvd. to be a 6-lane divided arterial street with 130 feet to 140 feet of right-of-way. Adequate right-of-way has been established for this roadway. Pathways Master Plan & Sidewalk Plan There are existing sidewalks along W. Southlake Blvd. adjacent to the site. TRANSPORTATION ASSESSMENT: There are two existing access drives onto this property. The proposed site plan eliminates the eastern access drive and utilizes the western access drive as a common access easement/driveway that will serve the subject property and the property adjacent to the west. Due to the existing Case No. Attachment A ZA19-0025 Page 2 median on W. Southlake Blvd. the access to both properties will be a forced right-in right-out. A TIA was not required for the proposed development. TREE PRESERVATION: The total existing tree cover on the property is 45.1%, and under traditional zoning a minimum of 50% of the existing tree cover would be required to be preserved. The applicant is proposing to preserve five (5) existing trees which equates to approximately 36% of the existing tree cover. The applicant is proposing to mitigate the removal of approximately two- hundred-eleven inches (211”) approximately one-hundred forty-one (141”) caliper inches by payment into the Reforestation Fund or planting trees on the adjacent Timberlake Subdivision HOA property. CITIZEN INPUT/ BOARD REVIEW: A SPIN meeting was held February 26, 2019. A 2035 Corridor Committee meeting was held January 24, 2019.

Tree Conservation/Landscape Review Keith Martin Landscape Administrator Phone: (817) 748-8229 E-mail: kmartin@ci.southlake.tx.us TREE CONSERVATION COMMENTS: 1. A portion of the 8’ wall along the south and east property boundaries are being offset to preserve Case No. Attachment C ZA19-0025 Page 2 four (4) existing trees, but if the wall is designed with a footing more than 25% of the trees critical root zone area will be altered. Provide clarification regarding the wall design and impact on the root zone are of the trees. ALTER; ALTERS; ALTERATION: Any act which causes or may reasonably be expected to cause a tree to die, including but not limited to, any of the following: uprooting any portion of the tree’s root system; severing the main trunk of the tree; inflicting damage upon the tree’s root system by machinery, storage of materials, or the compaction of soil above the root system of a tree; changing the natural grade of the critical root zone of a tree or uphill from the critical root zone of the tree so as to divert the flow of water to or away from the critical root zone; applying herbicidal or other lethal chemicals to the tree or any portion of the critical root zone of the tree; placement of impermeable material over any portion of the critical root system of a tree; and trenching within the critical root zone. A protected tree shall be considered to be altered if one or more of the following occurs: more than twenty-five percent (25%) of the critical root zone is adversely affected, more than twenty-five percent (25%) of its canopy is removed, or the tree is disfigured to the extent a reasonable person would conclude the tree will not survive. * If the development were proposed as traditional zoning, the proposed existing tree cover preservation would not comply with the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance 585-E. The total existing tree cover on the property is 45.1%, and under traditional zoning a minimum of 50% of the existing tree cover would be required to be preserved. The applicant is proposing to preserve five (5) trees along the east and south property lines equaling 36% of the existing tree cover. The applicant is requesting a variance to the Existing Tree Cover Regulations of the Tree Preservation Ordinance and is proposing to mitigate the removal of approximately one-hundred- forty-one inches (141”) by payment into the Reforestation Fund and/or planting trees on the adjacent Timberlake Subdivision HOA property with the HOA’s permission, as stated within the Development Standards and as noted on the Tree Conservation Plan. * Except as provided by subsection 7.2.b. of the Tree Preservation Ordinance, a Tree Conservation Analysis or Tree Conservation Plan shall be approved if it will preserve existing tree cover in accordance with the percentage requirements established by Table 2.0. If the property has previously received a tree permit related to development, the percentage of existing tree cover at the time the first such permit was issued shall be used to calculate the minimum existing tree cover that must be preserved under this section. Table 2.0 – Existing Tree Cover Preservation Requirements Percentage of existing tree cover on the entire site Minimum percentage of the existing tree cover to be preserved* 0% – 20% 70% 20.1 – 40% 60% 40.1% - 60% 50% 60.1% - 80% 40% 80.1% - 100% 30% *The minimum percentage of existing tree cover to be preserved shall exclude any area in public rights-of-way as approved by City Council. For property sought to be zoned for the Downtown zoning district or a planned development zoning district, including an S-P-1 Site Plan, S-P-2 Site Plan, Transition, Rural Conservation, Case No. Attachment C ZA19-0025 Page 3 Planned Unit Development, or Employment Center zoning district, the City Council shall consider the application for a Conservation Analysis or Plan in conjunction with the corresponding development application (as established in Table 1.0). The Planning and Zoning Commission shall review the application and make a recommendation to the City Council regarding the application. The City Council shall approve the Plan or Analysis if the Council finds that the Plan or Analysis provides for the: i. placement of building pads, parking areas, driveways, streets, and utility easements so as to maximize the preservation of environmental features of the property including mature tree stands, natural creeks and ponds, and significant grades; ii. maximizes the preservation of tree cover preservation areas indicated on the Environmental Resource Protection Map; iii. maximizes the preservation of existing tree stands with the potential to buffer residential areas from the noise, glare, and visual effects of nonresidential uses; iv. maximizes the preservation of existing trees, if any, adjoining a natural or man-made drainage creek; v. maximizes the preservation of existing protected trees along rural roadways and other streets as identified and prioritized in the Street Typology designation; and vi. mitigation of altered trees through proposed tree replacement procedures pursuant to this Ordinance. * 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. LANDSCAPE COMMENTS: 1. The “Required” interior landscape area was corrected but the required minimum plant material was not corrected.
