The new process focused on environmental concerns and the inclusion of the public using a number of strategies, including: • Incorporating environmental concerns into the RTP update; • Conducting an Environmental Impact Report for the RTP; • Streamlining the project delivery process; and • Using GIS tools to model land use with transportation projects and environmental data layers. This focus meant that the 2004 RTP update differed from the traditional long-range planning process in a number of ways.

. For both roadway capacity and transit capacity projects, points were assigned based on each project's geographic proximity to six environmentally sensitive areas: Historic Resources, Wetlands, Floodplains, Parks, Water Bodies, and Small Area Supply Watersheds.

; • Evaluation and programming for projects included in the State Highway Operation and Protection Program; and • Evaluation of projects for a $4.5 billion bond measure, the Corridor Mobility Improvement Account. Cal-B/C measures four primary categories of benefits: • Travel-time savings; • Vehicle operating costs; • Safety benefits (accident cost savings)

Regional agencies within California have begun to assess the use of Cal-B/C or methods or parameters from Cal-B/C for their Regional Transportation Plan (RTP) project evaluation and prioritization processes.

with wildlife habitat preferences and movement patterns to model areas of the landscape that are important for wildlife movement. The highest priority linkages identified by each of these tracks were then combined with CDOT animal-vehicle collision data and transportation planning data to select a subset of high-priority wildlife linkages for further assessment.

The project then created and analyzed the overall connectivity of a network of functionally defined resource patches for each focal species. This involved four major steps: • Define habitat quality.

Vehicular Exposures and Potential Mitigations Downwind of Watt Avenue, Sacramento, California Breathe California of Sacramento-Emigrant Trails; The Health Effects Task Force conducted the Watt Avenue case study. There is increasing scientific evidence suggesting that mobile source air toxics are harmful to human health.

70 percent of all the impact of toxic air contaminants in California, deposit deep into the lung, and possess significant risk to human health. The data establish that vehicular particulate matter directly downwind of Watt Avenue is at unhealthy levels for subjects that have to bear long-term exposure, even though aerosol mass does not violate any state or federal particulate matter standards.

The EEP provides an alternative to typical environmental planning around transportation projects by integrating natural resource issues into the transportation planning process. The program employs a proactive, long-range planning approach that involves identifying priority watersheds for protection and then assessing the impact of potential transportation projects in those watersheds.

Florida Department of Transportation's Environmental Transportation Decision-Making Process Florida is one of the pioneering states in the development and use of general performance-based planning. The 2025 Florida Transportation Plan sets the long-range goals and objectives that guide investment decisions.

, the ETDM public web site provides a convenient one-stop location for advocates and interested parties to collect information on the status of an FDOT project. Data Collection – The Florida Geographic Data Library The ETDM process is entirely web-based, relying on the Environmental Screening Tool, which resource agencies access on-line to view project information, perform customized GISbased analysis, offer alternatives, and present comments.

This final point is well illustrated by the many overlapping transportation planning initiatives currently taking place in Florida. Examples of other programs that are connected to Future Corridors include the Efficient Transportation Decision Making (ETDM)

The first, Mobility and Connectivity, consists mainly of measures that currently are in use at various levels of transportation planning, and depend on data sources that are readily available, such as traffic counts, origin-destination flows, and statewide and regional travel demand models. While the screening criteria do not yet include specific targets, they are linked to currently available data sources.

From page 95... ...
Under the new ETDM program, resource agencies whose input is necessary for environmental review will now be involved earlier and more thoroughly. As projects progress through the planning, programming, and implementation stages, each ETDM agency, through interaction with regional liaisons, uses the web-based Environmental Screening Tool to examine, analyze, and comment on transportation projects.
