Southlake Blvd. and 650 S. Carroll Ave. LEGAL DESCRIPTION: Portions of Tracts 3D, 3D2 and 3, Obediah W. Knight Survey, Abstract No. 899 LAND USE CATEGORY: Medium Density Residential CURRENT ZONING: “AG” Agricultural District REQUESTED ZONING: “R-PUD” Residential Planned Unit Development District HISTORY: There is no development history at the project site CITIZEN INPUT: A SPIN Town Hall Forum was held for this project on June 23, 2015 at Southlake Town Hall. A SPIN Meeting Report is included as Attachment “D” of this report. SOUTHLAKE 2030: Consolidated Future Land Use The Southlake 2030 Future Land Use Plan designates this property as Medium Density Residential. As proposed, this development is consistent with the Future Land Use Plan. The image to the right illustrates the Future Land Use for the proposed location. Master Thoroughfare Plan Zena Rucker Road currently does not connect between Byron Nelson Parkway and Carroll Avenue. Access to this proposed subdivision is contingent upon the construction of Zena Rucker Road, which according to the Southlake Master Thoroughfare Plan is designated as a 2-lane collector (C2U) with a minimum 60’ R.O.W. required. A minimum radius of 400’ and minimum tangent length of 50’ between curves is required per Subdivision Ordinance No. 483. This development as proposed is dependent upon acquisition of offsite R.O.W. and construction of a portion of Zena Rucker Road. Note, the applicant is not proposing to finish the connection of Zena Rucker Road between Byron Nelson Parkway and Carroll Avenue; the street is proposed to stub approximately leaving 600’ to the nearest cross street to the east. Mobility Master Plan The Mobility Master Plan recommends the extension of Zena Rucker Road east to S. Carroll Avenue. Below is the recommendation as written within the Mobility Master Plan. The proposal for Matthews Court states that in conjunction with the installation of culverts immediately west of the neighborhood by the City, Zena Rucker Road will be extended across these culverts and along the frontage of the neighborhood by the developer, which Case No. Attachment A ZA15-071 Page 1 will bring Zena Rucker Road closer to its ultimate connection at Tower Boulevard which will then complete the alternative connection between S.

Pathways / Sidewalk Plan The Official Pathways Map, adopted by City Council on January 7, 2014 designates that the north side of Zena Rucker Road is designated as having a future sidewalk that is less than 8 feet wide and the south side of Zena Rucker Road is designated as having a future multiuse trail that is greater than or equal to 8 feet wide. The pedestrian access plan for Matthews Court shows a continuation of the existing 8 foot wide hike & bike trail on the south side of Zena Rucker Road, which was designed to connect with the future trail to the east and the west. Carroll/1709 Small Area Plan The Carroll/1709 Small Area Plan was approved by City Council on September 20, 2011. The following recommendations are relevant to the medium density cluster residential area designated on the Illustrative Recommendations Map (below chart). Ref. Issue Recommendation No. LU3 1.

Tree Conservation/Landscape Review Comments Keith Martin Landscape Administrator Phone: (817) 748-8229 Case No. Attachment E ZA15-071 Page 3 Fax: (817) 481-5713 E-mail: kmartin@ci.southlake.tx.us TREE CONSERVATION COMMENTS: * Most of the existing trees on the site are pioneering tree species that have grown on the site in the past 5 to 10 years. They consist of Hackberry, Cedar Elm, and American Elm which are multi-trunked or in clusters that sprouted after being brush hogged and then left to grow. The most prominent quality trees are along the west property boundary of the property where they are proposed to be preserved. The Developer has also chosen the most prominent quality trees in the interior of the property to preserve. * The proposed zoning for the development is Residential Planned Unit Development, R-PUD. The submitted Tree Conservation Plan falls 5.7% short of complying with the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance for a standard zoning district. RPUD zoning districts are subject to City Council approval. To mitigate the removal the applicant is proposing to provide eighty (80”) caliper inches of landscape trees in the open space, and a minimum of twenty- four (24”) caliper inches of shade trees and two (2) understory trees will be planted on each lot when a house is built. A minimum total of two-hundred-seventy-two (272”) of new trees will be planted throughout the development. There is 39.8% of existing tree cover on the site and 60% of that existing tree cover is required to be preserved. The applicant is proposing to preserve 54.3% of the existing tree cover. For property sought to be zoned for, Planned Unit Development 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 Case No. Attachment E ZA15-071 Page 4 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. * Indicates informational comment. # Indicates required items comment.
