Evaluating Northern Long Eared Bat use of trees along highway corridors
Very little information is available on the Northern Long Eared bat’s likely use of vegetation flanking highway corridors. The objective of this research is to review existing data on the…
Survey and compilation of on- and off-structure bat mitigation approaches and designs
Survey of DOTs, MPOs, LPAs and NGOs regarding bat management strategies, mitigation on and off structures, effectiveness, and general cost benefit analysis including maintenance implications and costs.
Long-Term Cost/Benefit Analysis of Traditionally Sized Structures versus Aquatic Wildlife Friendly Structures and Culvert Replacement Cost Estimator
Traditionally, state and local governments install the smallest structure necessary to pass a certain measurable flow as required by local, state and federal rules. Structures that are sized to bankfull-width…
Survey and compilation of effective designs for promoting sensitive reptile and amphibian crossings of roadway corridors
Survey of DOTs, MPOs, LPAs and NGOs regarding designs for promoting sensitive reptile and amphibian crossings of roadway corridors, effectiveness, and general cost benefit analysis including maintenance implications and costs.…
The Efficacy of Treating Highway Runoff to Meet Watershed TMDL Goals
Background: State Departments of Transportation (DOTs) are being named as Designated Management Agencies in Total Maximum Daily Load (TMDL) management plans. This designation often brings with it the obligation for…
Survey of wildlife-friendly temporary and permanent erosion control products and approaches
Survey and compilation of information on erosion control products that are safe for sensitive reptiles and amphibians (netting-free) and erosion control treatments (alternatives to rip rap) that do not block…
Development of a Model Monitoring Program for a DOT
Background: Many NPDES Permits require DOTs to monitor receiving waters to characterize runoff from DOT facilities, assess the effectiveness of BMPs, and for compliance with TMDLs. Monitoring programs require considerable…
Survey of state and sensitive species databases characteristics and user ratings; which characteristics make online species databases most useful to users?
Survey of DOTs on use of on-line species databases and available GIS data. Which databases are most useful and what are the characteristics that make them useful (resolution and accuracy…
Porous Aspahlt Pavement Maintenance Evaluation
The use of porous asphalt pavement (PAP) can purify stormwater runoff and recharge the groundwater. PAP is one of the acceptable structural Best Management Practices (BMPs) that can be used…
