... Certain data are sometimes difficult and costly to obtain. Instead of working with resource agencies, transportation agencies often collect primary data themselves (Cambridge Systematics, Inc., forthcoming; Venner, 2003)

... . On-line statewide GIS repositories are making a variety of previously unavailable datasets known to transportation planners, including air quality, endangered species, wetlands, and water quality data (VIGN, 2007; WiscLINC, 2007)

... The non-binding document and map serves as an informational resource to planners and engineers, providing suggestions for the incorporation of these linkage zones into their management planning to address wildlife connectivity at an early stage of the process. Sample Measure: Each transportation project is evaluated in the context of the Wildlife Linkage Assessment, and what the probable impact will be.

... Losses of Riparian and Floodplain Areas – Impact of transportation construction on the quality, quantity, location, and functioning of the areas adjacent to the affected water bodies that strongly influence water quality. Water Resource Plan Consistency – Consistency between water resources and watershed management plans and transportation project plans.

... Regulated by the Clean Water Act, wetlands can be addressed by the watershed and ecosystem approaches identified under the water quality and ecosystems factors. There has been a recent move toward the consideration of wetlands quality,and not solely quantity, in project planning and programming processes.

... • Meet National Ambient Air Quality Standards; and • Reduce carbon monoxide and particulate matter hotspot violations.Table 5.4 presents two broad performance measures to address these objectives and specific applications of each performance measure. The case study highlight illustrates how carbon monoxide and particulate matter concentrations are measured in the Minnesota DOT's 2003 Statewide Transportation Plan.

... The case study highlight illustrates how air toxics exposure was measured in the Sacramento/I-5 Aerosol Transect Study. Energy, Materials, and Waste The SHRP 2 C02 framework is primarily focused on the evaluation of major highway capacity projects in planning, project development, and environmental review.

Environmental Measures – Climate Change FactorSHRP 2 Framework Measure Specific Measure Applications Air Toxics Concentrations – Impact of transportation construction on concentrations of mobile source air toxics. Air Toxics Exposure – Proximity of vulnerable populations potentially affected by mobile source air toxics.

... Assessments may include proximity of the proposed highway project to receiving waters within identified water protection areas, encroachment on riparian or other sensitive areas, projected increases in pollutant load due to the project (related to runoff, displacement, or hydromodification) , impacts on compliance with established water quality standards, consistency with existing water resource plans, or impacts on impervious surfaces (considering the highway itself as well as associated induced development)

... Investment in a meta-analysis of existing site-specific MSAT studies could help to identify best practice mitigation measures that may reduce the need for near-road air toxics monitoring; and 3. Provision of support for ongoing efforts outside of the DOT community to advance the state of knowledge about MSAT exposure and health effects.

... Such a platform should incorporate data on facility location, emergency evacuation routes, land and facility elevations, locations of protectivestructures; and trends in precipitation levels, temperatures, storm surge heights, relative sea level rise, and location and duration of flooding events. It should enable scenario-based analyses involving differing assumptions about precipitation levels, temperatures, relative sea level rise, severe storm frequency and intensity, storm surge heights, and areas of inundation.
