The elevations of the proposed buildings have changed to an updated fagade design to reflect current trends. Materials have changed from brick and stone to painted brick (light color or white in color). The building elevation exhibits are presented in Attachment C, pages 7-10. The applicant is requesting that all previously approved regulations, variances and stipulations as approved with the previous zoning approval (ZA 07-139) remain in effect. This includes the following: Regulations "S -P-1" Detailed Site Plan District with "O-1" Office District uses and development regulations with the following exceptions: 1. Portions of bufferyards along interior lot lines shall not be required as shown on the site plan. 2. The future buildings shall be similar in design and construction and shall match the exterior elevations, roof height, style and design, building materials and exterior color of the building to be constructed on Lot 1 R2. 3. All building setback lines and site improvements shall be as depicted on the site plan. Case No. ZA15-093 The applicant has restated these conditions in a letter dated October 16, 2015 and attached on Attachment C, p. 5.

(ZA07-139) Consolidated Land Use Plan The Southlake 2030 Future Land RC.—I Use Plan designates this property as Office Commercial. This designation is defined as; The cep" Office Commercial category is a commercial category designed and intended for the exclusive use of 6etluSe office and limited office -related activities. It is established for and will be allocated to those districts best suited for supporting commercial activity of an office character. It has been established to encourage and permit general professional and business offices of high quality and appearance, in attractive landscaped surroundings with the types of uses and design exterior appearance so controlled as to be generally Attachment A Page 1 compatible with existing and future adjacent and surrounding residential development. Properties with this designation may serve as a transition between established residential neighborhoods, major roadways, and retail development. Other suitable activities are those permitted in the Public Parks/Open Space and Public/Semi-Public categories. The development appears to be consistent with the intent of the office commercial land use designation at this location. Master Thoroughfare Plan The Master Thoroughfare Plan recommends S. Nolen Drive to be a 3 -lane undivided arterial street with 70 -feet of right-of-way north of Crooked Lane. Currently, sixty -foot rights-of-way exist along Crooked Lane, S. Nolen Drive and Silicon Drive. Pathways Master Plan The Pathways Master Plan recommends a less than 8 -foot sidewalk along Crooked Lane, S. Nolen Drive and Silicon Drive. The applicant has shown 5 - foot sidewalks along Crooked Lane, S. Nolen Drive and Silicon Drive. TRANSPORTATION ASSESSMENT: Area Road Network and Conditions The proposed development will have one (1) access directly onto S. Nolen Drive and one (1) access directly onto Silicon Drive. Common access easements have been provided between lots for shared parking and drive lanes. South Nolen Drive and Silicon Drive are 2 -lane, undivided local commercial streets within the Cornerstone Business Park development. There are no traffic counts for S. Nolen Drive or Silicon Drive adjacent to this site.

A straight "O-1" Office District zoning would require 40% preservation of the existing trees (65%) on the site. The applicant has indicated there is 65% tree coverage on this site (this calculation includes trees located in the right-of-way) and has indicated 40% of the existing cover is to remain (this includes approximately 10% of the trees located within the right- of-way). The Landscape Administrator has determined that the actual applicable tree cover preservation is approximately 30%. The applicant has included a regulation to the development regulations to allow the tree preservation as shown. The sanitary sewer utility installation along Crooked Lane right-of-way and the Case No. Attachment A ZA 15-093 Page 2 lots may impact the existing trees. The Landscape Administrator has noted that both the utilities and grading are to be limited in altering the critical root zone areas of the existing trees proposed to be preserved. UTILITIES: A 12 -inch water line currently exists along the east side of S. Kimball Avenue. An 8 -inch sanitary sewer line currently exists along the west side of S. Kimball Avenue. PLANNING AND ZONING COMMISSION: October 22, 2015, Approved (5-0) subject to the Staff Report dated October 16, 2015 and further subject to the Site Plan Review Summary No. 3 dated October 16, 2015. STAFF COMMENTS: Attached is Site Plan Review Summary No.4, dated October 23, 2015. Prior to receiving a building permit, a copy of the filed shared parking and shared maintenance agreement must be received by the City. The maintenance agreement should include provisions for fire lanes and trash enclosure/use.

The actual existing tree cover preservation is probably somewhere in the low 30% range which does not comply with the Existing Tree Cover Preservation Requirements. Tree Conservation Plan shall be approved if it will preserve existing tree cover in accordance with the percentage requirements established by Table 2.0. 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, 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 Case No. Attachment D ZA 15-093 Page 2 vi. mitigation of altered trees through proposed tree replacement procedures pursuant to this Ordinance. There are utilities, storm sewer, and grading proposed within the critical root zone area of the existing trees proposed to be preserved. Design both the utilities and grading to limit the alteration of the critical root zone areas of the existing trees proposed to be preserved. 3. The proposed Sanitary Sewer along Crooked Lane cuts directly through the critical root zone area of trees that would be preserved. The installation of any off-site utilities will be required to be bored. Please ensure that the utility services for each of the lots are laid out as to not alter the critical root zones or health of the trees that are intended to be preserved. Boring: Boring of utilities under the critical root zone of a protected tree shall be required in those circumstances where it is not possible to trench around the critical root zone of the protected tree. When required, the bore shall be a minimum depth of forty-eight (48) inches. 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 AND BUFFERYARDS COMMENTS: Existing tree credits are proposed to be taken. Credits shall only be granted if the tree/s are in healthy condition and all requirements of the Tree Preservation Ordinance have been met as determined at the time of inspection for a Permanent Certificate of Occupancy.
