Survey Responses C-3 Comments: CA—We have licensed and non-licensed landscape architects and engineers in design, construction, and maintenance. We also have maintenance personnel trained for all the various functions that maintenance performs. IA—Landscape Architect signs off on the planting plans, construction inspectors are typically licensed engineers, and herbicide applicators for maintenance are licensed. KS—No special training other than our normal training of our employees working in a work zone. MD—No specialized training for Urban Freeway projects above and beyond that which is required for all work performed in the State Right of Way. MI—Designers have Landscape Architect degrees. MN—Landscape installation contractors are required to be certified by MnDOT. MO—Landscape projects will include Roadside Managers at the District level. MT—Certified Licensed applicators NC—No official certification is required but we only use professional firms and staff qualified in Landscape Architecture. OH—We have a Highway Technicians (HT) course that shows HTs how to establish, inspect and maintain vegetation. RI—herbicide licenses SC—Designers must be licensed engineer or landscape architect. VT— Pesticide Applicator Certification WA—Designers are landscape architects, and maintenance personnel are certified herbicide applicators and trained in Integrated Vegetation Management. WV—We would require nothing above the requirements for any other project. If you answered No to all of the previous questions, please submit the survey. Thank you for your time.

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.
