EXECUTIVESUMMARYPROGRAM GOALSRapid growth along South Lamar Boulevard has created safety and mobility concerns along thecorridor. The South Lamar Corridor Transportation Improvement Program was created toimprove safety and accessibility along the corridor, while also improving mobility for everyonepeople who walk, people who bike, those that use transit and those that drive. The program aimedto identify future transportation needs of the corridor and enhancements that could help to createa multimodal transportation system supportive of mixed-use, pedestrian and bicycle friendlydevelopment patterns.PROJECT PROCESSThe City of Austin has initiated a series of corridor improvement programs to ensure Austinroadways are up to today’s community standards. A framework has been developed for these corridorprograms to allow for a common approach while the specific character and needs of the differentroadways and communities are assessed.The City of Austin and the consultant team began the project by developing a public involvementprogram and reaching out to community stakeholders and neighborhood associations. Involvementfrom these groups was a vital component to fully comprehending the South Lamar BoulevardCorridor. Existing corridor conditions data were collected and changes in traffic patterns in recentyears were analyzed. Conditions of the existing infrastructure along the corridor were documented,and future area development and planned improvements were considered along with the vision andgoals of the Imagine Austin Comprehensive Plan.EXISTING CORRIDOR CHARACTERISTICSThe character of South Lamar Boulevard changes traveling south from Riverside Drive, althoughthis character change is becoming less marked with the rapid development in the project area.Proximity to downtown has contributed to denser growth at the northern end of the corridor.Multi-family housing adjacent to the corridor along with restaurants and retail have been tricklingsouthward to claim available land further away from downtown. Several different neighborhoodslie along the length of the corridor, and different types of business and attractions are interspersedamong them. The south end of the Lamar corridor exits the project area through the large twinshopping centers at Brodie Oaks.The auto-centric nature of South Lamar Boulevard is in transition, with density increasing and morepedestrian-friendly places moving in due to the proposed land use plan. The corridor is alreadyheavily developed, with little green space abutting the roadway.Six character zones can describe South Lamar:SOUTH LAMAR CORRIDOR IMPROVEMENT PROGRAMAUSTIN MOBILITY // CITY OF AUSTIN TRANSPORTATION DEPARTMENT // APRIL 2016E-1

Zone 1: Riverside Drive to BartonSprings RoadZone 2: Barton Springs Road toTreadwell StreetZone 3: Treadwell Street to Mary/Heather StreetZone 4: Mary/Heather Street toManchaca RoadZone 5: Manchaca Road to PantherTrailZone 6: Panther Trail to US 290/Ben White BoulevardThese six zones are further discussed inChapter 3.ROADWAYSouth Lamar Boulevard is largely a fourlane facility with a continuous centerturn lane utilized to access the manybusinesses and connecting streets.Dedicated left turn lanes are providedat all signalized intersections. Sectionsnorth of Barton Springs Road and atBrodie Oaks Shopping Center havethree lanes in each direction with araised median.There are 12 signalized intersectionsalong the corridor, and numerousunsignalized intersections, some ofwhich intersect Lamar Boulevard at asignificant angle. A large number ofcommercial driveways provide access tothe many businesses, restaurants, andresidences that border the corridor.TRANSITCapital Metro operates several bus lines along South Lamar Boulevard. There are four MetroBusroutes in operation and one MetroRapid route. Capital Metro’s All Systems Go! transit plan identifiedthe project area segment of South Lamar as a bus rapid transit corridor. The Burnet/South Lamaror Route 803 is one of these routes with five stops (Barton Springs, Lamar Square, Oltorf West,Bluebonnet, Brodie Oaks) along the project corridor. This MetroRapid line is equipped with “hightech” and higher-capacity buses with signal pre-emption capability and stations equipped with realtime arrival technology.PEDESTRIANSidewalk conditions along South Lamar Boulevard offer considerable opportunity for improvement.While sidewalks are primarily continuous and of adequate width, there are several sections whereSOUTH LAMAR CORRIDOR IMPROVEMENT PROGRAMAUSTIN MOBILITY // CITY OF AUSTIN TRANSPORTATION DEPARTMENT // APRIL 2016E-2

sidewalks are broken or missing. Where sidewalks are present, widths range from 4-feet to 6-feet andare generally directly adjacent to the roadway on the west side and separated by a grassy median onthe east side of South Lamar Boulevard. In several locations, utility poles located in the middle ofthe sidewalk or missing ADA ramps cause accessibility issues. In areas where new development hasoccurred, sidewalks are even wider and setback from the roadway with a landscaped buffer.BICYCLECurrent bicycle facilities on South Lamar Boulevard consist of mostly continuous, but narrow,5-foot bicycle lanes adjacent to the main traffic lanes. Where the bike lanes are not present, cyclistsshare the road with fast-moving traffic. The facility is generally considered to be unsuitable forregular use by a majority of commuter and recreational users. There are also multiple bus stops alongthe corridor, and frequent bus service directly conflicts with the bike lane.The City has recently installed bike lanes on the south end of the corridor, near the Brodie OaksShopping Center.DRAINAGEThree watersheds are located within the project area of the South Lamar Corridor including the LadyBird Lake Watershed, Barton Creek Watershed, and the West Bouldin Creek Watershed. Most of theproject area lies within the West Bouldin Creek Watershed. Fifteen drainage systems consisting ofpipes and culverts were identified in the project area through site visits, City GIS data and hydraulicmodels and record drawings. The drainage analysis showed that of the fifteen systems, only two meetcriteria for the 25 year event level of service. A project to improve the area storm drainage is listed inthe Capital Improvement Projects for Fiscal Year 2015 and includes the South Lamar Corridor.PROJECT GOALS AND DESIGN CONSIDERATIONSIt is the intent of this project that the recommended improvements will improve mobility for nearbyresidents and commuter through-traffic. Commuter solutions such as advanced technology, andimprovements in infrastructure and transit operations can help to improve operations along thecorridor. Building enhanced facilities for other modes such as bikes, pedestrians and transit willprovide increased options for people to conduct daily activities such as trips to school, work, or toaccess corridor amenities.Recommendations developed for South Lamar Boulevard were based on input from the publicmeetings and stakeholder meetings, the results of land use and traffic analyses, and several relatedTransportation Demand Management (TDM) strategies. These recommendations will guide the Cityof Austin in shaping South Lamar Boulevard into a multimodal corridor that supports everyonepeople who walk, people who bike, people that use transit, and people that drive. The Imagine Austinvision statement recognizes that Austinites are committed to preserving the best of Austin andchanging those things that need to be changed.Corridor concepts developed for South Lamar Boulevard envision a smartly planned facility thatserves all modes of transportation, encourages active transportation and enhances safety overall.During the public involvement process, many people indicated they would walk or bike more givena safer facility to use to reach their destinations. It is the goal of the City of Austin and projectplanners that the proposed concepts for South Lamar Boulevard serve both the vehicle demands ofthe facility, while accommodating and encouraging alternative modes.SOUTH LAMAR CORRIDOR IMPROVEMENT PROGRAMAUSTIN MOBILITY // CITY OF AUSTIN TRANSPORTATION DEPARTMENT // APRIL 2016E-3

In support of the Complete Streets policy, the ultimate cross section proposed for South Lamarwould include protected bike facilities and wider, completely connected sidewalks for bothnorthbound and southbound travelers.The facility will continue to serve four lanes of traffic, as it always has, and will also allow fortransit improvements in locations that make sense and where space allows. In place of the existingcontinuous and unmanaged center turn lane, a raised median will help to reduce conflict andstreamline access to businesses. This median can also serve as a pedestrian refuge for people wantingto cross the busy corridor, thereby improving safety for foot traffic and motorists alike.Recommended Ultimate Cross SectionThe growing awareness and understanding of the effects of the built environment on publichealth has been reflected in several recent Austin and Travis County strategic plans. In orderto realize the health-related goals of these plans, this corridor study included a Health ImpactAssessment (HIA). The HIA sought to assess potential health impacts of policies, projects orprograms that affect the public and to identify opportunities to maximize positive health effectsand minimize potential negative outcomes. The HIA was performed in order to obtain twoimportant goals: To help the project’s lead planning firm (HDR) consider public health impacts during theplanning processTo provide the public and decision-makers with a) information on the potential health impactsof the proposed plan(s); b) prioritization of improvements in terms of health outcomes; andc) approaches to evaluate future health outcomes related to the corridor improvementsSOUTH LAMAR CORRIDOR IMPROVEMENT PROGRAMAUSTIN MOBILITY // CITY OF AUSTIN TRANSPORTATION DEPARTMENT // APRIL 2016E-4

Figure ES-1: Future Corridor Concept for South LamarSOUTH LAMAR CORRIDOR IMPROVEMENT PROGRAMAUSTIN MOBILITY // CITY OF AUSTIN TRANSPORTATION DEPARTMENT // APRIL 2016E-5

Improvements to the South Lamar corridor in the form of pedestrian and bicycle facilities,roadway, and public green spaces have substantial potential to impact health of the neighboringcommunities. Given the size of the population and interest in active transportation, facilitiesshould offer separated space for people who want to walk and bike. Facilities should also beplanned to accommodate a large volume of non-motorized travelers.FUTURE CORRIDOR CHARACTERISTICS AND RECOMMENDATIONSSouth Lamar Boulevard offers many amenities and is a major destination in South Austin. The recentprojects that have sprung up in the area along with the many that are in the planning stages willcontinue to increase density along the corridor. More and more pedestrian-friendly destinations couldsee an increase in multimodal activity in the future.Recommended improvements for South Lamar Boulevard are based on the complete streets andcorridor concepts. Improvements have been identified as short- (0 – 5 years) or long-term (5 – 20years) to help the City of Austin prioritize based on need and feasibility and also to allow the Citytime to raise the needed funds. Table ES-1 summarizes the recommended improvements that couldbe implemented in the short-term.Table ES-1.

LONG-TERM IMPROVEMENTSLong-term projects are recommended for implementation within five to twenty years, and mayrequire more funding to implement than short-term projects. To obtain the necessary right-of-wayneeded to build the full recommended cross section for South Lamar Boulevard, properties along thecorridor will have to wait until redevelopment occurs. Long-term recommendations will need time toenact.
