SOUTHLAKE 2030 PLAN: Consolidated Future Land Use Plan The site is designated “Low Density Residential”, which specifies single family detached dwellings at a net density of one or fewer dwelling units per acre. The proposed residential development is consistent with this designation. Mobility & Master Thoroughfare Plan The Mobility and Master Thoroughfare Plan shows Shady Ln. to be a local residential street with 50’ of right of way. Adequate right of way is shown to be dedicated on the plans. Pathways Master Plan & Sidewalk Plan The Pathways Master Plan and Sidewalk Plan shows a >8’ Multi-Use Trail extending from Shady Lane through the Corps of Engineers property to the Grapevine city limit. No trail connection through the property to the Grapevine city limit is required or proposed. Subdivision Ordinance No. 483, as amended requires 4’ sidewalks along all local residential streets and the required sidewalks are shown on the plan. Case No. Attachment A ZA15-044 Page 1 TRANSPORTATION ASSESSMENT: Existing Area Road Network and Conditions The Preliminary Plat proposes one street with access onto Shady Lane, which is a local residential street.
