Item 9BCity of Southlake Department of Planning & Development Services S T A F F R E P O R T October 10, 2007 ZA07-107 CASE NO: Plat Revision for Lots 7R1R, 7R2R, & 7R3, Timberline Estates PROJECT: REQUEST: On behalf of Paula Kellar, Steve Maples is requesting approval of a plat revision for the creation of three (3) residential lots on 4.805 acres at the end of Timberline Lane. Two (2) existing lots are proposed to be subdivided into three (3) new lots, creating a net increase of one (1) lot on the 4.805 acres. The following variances are being requested:  Sidewalks: A minimum 4-foot sidewalk is required along both sides of all public streets. The applicant is requesting a variance to the sidewalk requirement. (Subdivision Ord. No. 483, Section 5.06.B.2.a)  Trail: A 10-foot Pedestrian Access Easement currently exists on the east side of this property connecting to the Stonebridge Park commercial property to the south and thus providing pedestrian access from W. Southlake Boulevard to Johnson Road. An 8-foot multi-use trail is planned within the easement. The applicant is requesting a variance to the construction of the trail and is requesting that the 10- foot Pedestrian Access Easement be abandoned. (Subdivision Ord. No. 483, Section 5.06.B.2.b) Because this plat proposes the dedication of a public street and extension of public utilities, a preliminary plat application (ZA07-100) is being considered in conjunction with this plat revision. One document is being presented for the dual purpose of a preliminary plat and a plat revision.

TRANSPORTATION Master Thoroughfare Plan ASSESSMENT: The Master Thoroughfare Plan does not make any recommendations for Timberline Lane. Existing Area Road Network and Conditions The proposed lots will have direct access onto Timberline Lane by a proposed street and cul-de-sac extension. Timberline Lane is currently a local residential street that intersects with Johnson Road. Johnson Road is currently a 2-lane, undivided roadway. The capacity of the existing roadway is approximately 8,400 vehicle trips per day. Under this condition, the roadway would be considered to operate under a level of service ‘D’. Completion of this development will add approximately 29 vehicle trips per day to this section of Johnson Road, bringing it to 1,888 vehicle trips per day.

PATHWAYS MASTER PLAN: The Southlake Pathways Master Plan proposes an 8-foot multi-use trail along the western property line adjacent to the creek channel to ultimately connect Florence Road to W. Southlake Boulevard. Upon platting in 2005, a 10-foot pedestrian access easement was dedicated at the end of Timberline Lane, providing an immediate connection from a public Right-of-Way to the commercial property to the south. Staff has recommended that the applicant continue to provide the existing 10-foot pedestrian access easement along the east property line as this would eliminate potential complications of acquiring additional easements along the creek channel and will insure the ability to complete the intended trail connections. The owner has, however, requested a variance to the trail requirement and that the easement be abandoned. WATER & SEWER: These lots shall be served by a public water line. The 6-inch water line in Timberline Lane will have to be extended to serve these properties. The Fire Marshal will also require a fire hydrant at the end of the cul-de-sac. A 12-inch sanitary sewer line exists along the rear property line. TREE PRESERVATION: See attached Plat Review Summary No. 2. DRAINAGE ANALYSIS: This property drains to the west toward the existing, natural drainage way along the back of the lot.
