Item 6B MTP AMENDMENT KIRKWOOD EXTENSION ALIGNMENT/ N. CARROLL AVENUE November 18, 2008 Presentation Outline Background Proposed Changes to the MTP Questions Master Thoroughfare Plan Role of the MTP Map Require reservation of adequate R.O.W. for future transportation improvements. Minimize the amount of land required for street purposes. Identify the functional role (collector, arterial) that each street should be designed. Allows the city to apply CIP funds and roadway impact fees. Informing citizens/developers of future thoroughfare plans. CURRENT MTP PLAN Kirkwood Alignment Carroll Avenue Designation KIRKWOOD BLVD. AMENDMENT Kirkwood Blvd. Background November 2001, Adopted Resolution 01-60 that show the general alignment of Kirkwood Blvd. through the Hines Property and Gateway Church Property but not the Carroll/Highland Intersection. November 2004, Adopted Resolution 04-066 that indicated a general alignment through the Carroll/Highland Intersection. July 2005, Adopted the MTP (2025 Plan). June 2008, PZ recommends that the alignment of Kirkwood Blvd through the Carroll/Highland Intersection be determined prior to a recommendation on the Hines property be made. Why is the Kirkwood Extension Needed? -SH 114 is designed to function as a regional arterial that: Carries traffic into Southlake (i.e shopping/work) Conducts traffic out of Southlake (i.e. Dallas commute) Pass-through Southlake. -SH 114 is not designed to carry locally generated trips. -Alleviate traffic on the SH-114 frontage roads (5%-15%). -Reduce traffic on E. Highland Avenue/Dove St. -Improve overall traffic circulation north of SH-114.

Carillon – First Submittal Development Plan This plan is diagrammatic only and is intended to show potential configuration. August 7, 2008 Carillon – Second Submittal KIRKWOOD BOULEVARD EXTENSION ALTERNATIVES Master Thoroughfare Plan Alignment Kirkwood – Multiple Options C E F D H Existing MTP – A4D A G B Kirkwood – Split Lot Option Burger Hines Stahala Incentives Factors to Consider Continue Kirkwood through the Intersection Significant reduction on traffic volumes along E. Highland Ave. Reduction in traffic along Dove St. Reduction in overall traffic along frontage roads. Increased east bound traffic along Highland at the Highland/Carroll intersection. Improvements in the LOS at the SH-114 frontage roads. Improved access to development areas results in reduced length of trip and overall U-turning movements N. CARROLL AVENUE DESIGNATION CURRENT MTP PLAN Kirkwood Alignment Carroll Avenue Designation Designation History 1989 MTP Designation - A4U – 84’ ROW 1991 MTP Designation - A5U - 84’ ROW 1997 MTP Designation - A3U - 94’ ROW (ROW sufficient to allow an A5U) 2005 MTP Designation - A2U – 88’ ROW Reason for the Change Traffic Study indicates that the future LOS at the key intersections (SH 114, Highland, and Dove) is D or less. Designation of Carroll Avenue as a 4 lane facility will allow the city the ability to consider expanding N. Carroll Avenue as a four (4) lane facility if traffic counts warrant. LOS Rankings-Highway Capacity Manual LOS Rankings-Highway Capacity Manual LOS – Existing Conditions LOS Background Traffic -2015 LOS Summary Source: Innovative Transportation Solutions Recommendation Add a note to the MTP similar to Dove – “Retain the existing designation of A2U (88’) with the provision to improve the roadway to an A4D (88’) arterial when traffic counts warrant”.
