Variance Approval Criteria for Tree Preservation Ordinance No. 585-D, Article 15.2: Variances — The City Council may authorize a variance to any provision of this Ordinance following a recommendation from the Planning and Zoning Commission. A request for a variance to any provision in this Ordinance shall be accompanied by a Tree Conservation Analysis or Tree Conservation Plan as outlined in Article 6, or other documentation requested by the Administrative Official, and the following factors shall be considered in evaluating the variance request: Whether a literal enforcement of the Ordinance will create an undue hardship or an unreasonable practical difficulty on the applicant; ii. Whether the situation causing the unnecessary hardship or practical difficulty is unique to the property and is not self-imposed; iii. Whether a reasonable accommodation or alternative solution can be made to accomplish the desired activity without the alteration of the tree; iv.

The following note shall be added to the plat: Compliance with the provisions of the city's Storm Drainage Policy does not relieve a person of the responsibility of complying with all other applicable laws, including, but not limited to, Section 11.086, Texas Water Code. Proposed dumpster encroaches an existing 15' utility easement. An encroachment agreement signed by the city and franchise utility companies is required prior to final acceptance of the project. SANITARY SEWER COMMENTS: A private septic system has been proposed to accommodate the proposed development as City's sanitary sewer is not available to the site.

Detailed drainage calculation will be verified during review of construction plans. Verify size, shape, and/or location of the detention pond (as depicted on the site plan). Any changes to size, shape, and/or location of the proposed pond(s) may require a revision to the concept/site/development plan and may need to be approved by the Planning and Zoning Commission and the City Council. Proposed driveway culvert must be sized by an engineer and submitted for approval to the City Engineer. Calculations will be required to verify capacity of proposed inlets and the existing ditch. Storm sewers collecting runoff from offsite areas and public right of way are considered public and shall be a minimum of 18" RCP and constructed to City standards.

Tree Conservation/Landscape Review E-mail: kmartin@ci.southlake.tx.us Keith Martin Landscape Administrator Phone: (817) 748-8229 TREE CONSERVATION COMMENTS: 1. The proposed Tree Conservation does not comply with the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance. There is 35.6% of existing tree cover on the site and 60% of the tree cover is required to be preserved. Only 51% of the existing tree cover is proposed to be preserved. A variance has been requested. 2. There is a Tree Mitigation Requirement calculation chart provided on the Tree Conservation Plan which proposes fifty-four inches (54") of tree removal mitigation trees to be planted. Neither the Tree Conservation Plan nor the Landscape Plan reflects the proposed planting of the mitigation trees. 3. There is a Tree Preservation Credits Calculations provided on the Tree Conservation Plan. What is it for? Credits for the preservation of existing trees may be taken for required interior landscape or bufferyard plantings but it is not reflected on the Landscape Plan. Case No. Attachment C ZA16-066 Page 3 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 Minimum percentage of the the entire site 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, 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: 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; 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 Case No. Attachment C ZA16-066 Page 4 structures, easements, utilities, structures grading, and any other structure proposed to be constructed do not conflict with existing trees intended to be preserved.
