The existing tree cover on the site is approximately 65.3% and 40% of that tree cover is required to be preserved. The current approved Tree Conservation Plan shows that 76% of the existing tree cover is to be preserved. The revised Tree Conservation Plan shows an additional 3.73%of existing tree cover to be removed for the Temporary Access Road,the bridge realignment and revised slope grading around the bridge and other portions of the permanent access road.Approximately 72.27% of the existing tree cover is proposed to be preserved which meets the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance.

Kirkwood Boulevard Contact: Keith Martin Phone: (817) 748-8229 Fax: (817) 481-5713 ---------------------------------------------------------------------- ---------------------------------------------------------------------- The following comments are based on the review of plans received on September 6, 2016 . Comments designated with a number may be incorporated into the formal review to be considered by either the Planning and Zoning Commission or City Council. Other items will not be addressed by either the P&Z or City Council. It is the applicant's responsibility to contact the department representative shown above and make modifications as required by the comment. ---------------------------------------------------------------------- ---------------------------------------------------------------------- TREE CONSERVATION COMMENTS: * TD Ameritrade is proposing to realign the site access road off of West Kirkwood Blvd. and the bridge that crosses the Kirkwood Branch Creek because of unforeseen interference with the existing topography grade elevations within the flowage easement along the creek. They are also proposing a Temporary Access Road off of West Kirkwood Blvd. to ease the construction of the access road and bridge. The existing tree cover on the site is 65.3% and 40% of that tree cover is required to be preserved. The current approved Tree Conservation Plan shows that 76% of the existing tree cover is to be preserved. The revised Tree Conservation Plan shows an additional 3.73% of existing tree cover to be removed for the Temporary Access Road off of West Kirkwood Blvd., revised access road realignment, and revised slop grading around the bridge and other portions of the access road. 72.27% of the existing tree cover is proposed to be preserved which meets the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance. * 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 Minimum percentage of the existing entire site tree cover to be preserved* 0%-20% 70% 20.1 —40% 60% 40.1% -60% 50% 60.1% -80% 40% 80.1% - 100% 1 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. Case No. Attachment D TRER16-0128 Pagel 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 orAnalysis provides forthe: 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 without approval of a Tree Removal Permit is a violation of the Tree Preservation Ordinance. 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.
