Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

A-1 A P P E N D I X A Survey Questionnaire Dear State Maintenance Engineer: The Transportation Research Board (TRB) is preparing a synthesis of practice on Design and Maintenance Practices for Urban Freeway Roadside Vegetation. This is being done for NCHRP, under the sponsorship of AASHTO, in cooperation with FHWA. The goal of the study is to document current practices used by transportation agencies to address design and maintenance of vegetation along high visibility urban freeways with limited pedestrian access, such as wider medians, interchanges, and overpasses. This survey is being sent to voting members of the AASHTO Committee on Maintenance. If someone else in your agency is better able to respond to this survey, please forward the survey or contact the PI for changes to the recipient listing and we will re-issue the invitation if needed. Participants are encouraged to share the survey response effort among personnel by following instructions provided on the first page of the survey. The questionnaire covers urban roadside landscape development and maintenance issues such as illegal and other unauthorized use of the right of way, work zone safety, cooperative maintenance agreements, training, and roadside maintenance costs. The web-based survey can be accessed at the following link: Please complete and submit this survey AS SOON AS POSSIBLE. If you have any questions, or would like assistance completing the survey, please contact our principal investigator Beverly Storey at b-storey@tti.tamu.edu, 979-845-7217. We realize that your time is limited and appreciate that you are willing to help us. Best regards, Beverly Storey

A-2 Landscape Development and Management Practices for Urban Freeway Roadsides 3. Does your agency have published policies, practices, programs and/or protocols (either statewide or specific to urban districts) that specifically apply to, reference and/or directly pertain to urban freeways, particularly limited access freeways, regarding the following? Please select all that apply and upload applicable documents and/or examples at Browse button at end of the survey. Landscape development, e.g., landscape design, sustainable development, etc. Statewide Specific to urban districts No Landscape maintenance, e.g., mowing, irrigation, plant replacement, herbicide treatments, etc. Statewide Specific to urban districts No Roadside integrated vegetation management plans Statewide Specific to urban districts No Illegal camping and other unauthorized uses of the right of way Statewide Specific to urban districts No Work zone safety for landscape maintenance personnel on limited access freeways Statewide Specific to urban districts No Cooperative landscape maintenance agreements with local entities Yes No 4. If you answered No to all of the previous questions, please submit the survey. Thank you for your time. 1. Please enter the state transportation agency you represent. 2. Each of the following questions requests that you supply current documents/examples regarding published policies, practices, programs and/or protocols (either statewide or specific to urban districts) that specifically apply to, reference and/or directly pertain to urban freeways, particularly limited access freeways. Each question asks for a different aspect of urban roadside design and maintenance. If you answer anything other than No to the following questions, please upload the most current document(s) using the Browse button provided at the end of the survey.

Survey Questionnaire A-3 6. Has your agency conducted research/performance measurement regarding the costs of maintaining an urban freeway landscape development in the following categories? Please select all that apply and upload applicable data at the Browse button at the end of the survey.

Current practices used by state departments of transporttion to design and manage the urban freeway roadsides (UFRs) environment is the focus of National Cooperative Highway Research Program (NCHRP) Synthesis 539: Landscape Development and Management Practices for Urban Freeway Roadsides.

The urban freeway roadsides (UFRs) for this synthesis are those roadsides associated with high visibility urban freeways with limited pedestrian access, such as wider medians, interchanges, and overpasses.

The UFR is part of a greater urban environment with broad social, political, economic, and environmental implications for management. There are numerous UFR stakeholders, such as their respective municipalities, residents, adjacent landowners and businesses, traveling public, and state DOTs, and each has specific requests, requirements, and considerations. Among these are an acceptable level of maintenance and stakeholder expectations for aesthetics.

State departments of transportation (DOTs) recognize their roadway systems are assets that need management and acknowledge that pavements and other infrastructure routinely require resurfacing, restoration, and rehabilitation because their integrity degrades over time. However, the UFR and its respective urban freeway systems may not receive the same routine restoration. The vegetation installed at the time of roadway construction ages with the surrounding infrastructure. Decades after initial installation within the UFR, transportation agencies have mature landscapes that may be near the end of their life cycle.

The inability to adequately access and maintain these areas can result in failure of planted vegetation, loss of investment, and public criticism of state DOTs. The UFR is part of state DOTs’ highway system investment facing many challenges as freeway renovations and expansions encroach on limited right-of-way (ROW) areas available for landscape development. As the size of these areas decreases, so does the ability of maintenance workers and equipment to safely access and maintain them.
