Integrating Conservation and Long-Range Transportation Planning Using a Strategic Assessment Framework

Casper, Craig Landon, Melissa A. Crist, Patrick J. Walker, Doug

The Pikes Peak Area Council of Governments Moving Forward metropolitan transportation planning process introduced a Strategic assessment planning framework to the Pikes Peak region. This framework was selected because it integrates multi-disciplinary qualitative and quantitative information from technical experts and regional stakeholders to determ...

DO BRIDGES AFFECT MIGRATING JUVENILE SALMON: TRACKING JUVENILE SALMON AND PREDATOR FISH MOVEMENTS AND HABITAT USE NEAR T...

Bloch, Philip Celedonia, Mark Tabor, Roger

Large anthropogenic infrastructure such as major bridges in and near waterways can influence the ecological dynamics of the nearby aquatic environment. These influences may affect behavior, habitat use, fitness, and survival of fishes. Chinook salmon (Oncoryhnchus tshawytscha) spawning in tributaries to Lake Washington typically spend three to five...

Potential Impacts of Climate Change on Urban Flooding: Implications for Transportation Infrastructure and Travel Disrupt...

Chang, Heejun Lafrenz, Martin Jung, Ii-Won Figliozzi, Miguell Platman, Deena

Climate change in the Pacific Northwest of America is likely to bring more frequent, heavier winter precipitation as temperature rises. These changes in precipitation patterns have significant implications in hydrology and socioeconomic sectors that could be affected by changes in hydrology. Transportation infrastructure and travel patterns are als...

EFFECTIVENESS OF MITIGATION MEASURES TO REDUCE ROAD MORTALITY IN THE NETHERLANDS: BADGER MELES MELES

Bekker, Hans G. J. Dekker, Jasja J. A.

In the 1900‘s, the badger population of the Netherlands was estimated to count 2500 to 3000 setts with over 4000 individuals. Between then and the 1960‘s, the number declined drastically and stayed low until the mid-1980‘s with about 400 setts in the whole of the Netherlands. In the 1980‘s a high percentage of the population, locally up to 25%, was...

An Analysis of the Efficacy and Comparative Costs of Using Flow Devices to Resolve Conflicts with North American Beavers...

Boyles, Stephanie L. Savitzky, Barbara A.

Road damage caused by beavers is a costly problem for transportation departments in the U.S. Population control and dam destruction are the most widely used methods to reduce road damage caused by beavers, but the benefits of such measures in some situations are often very short-term. At chronic damage sites, it may be more effective and cost-benef...

ECO-LOGICAL: AN ECOSYSTEM APPROACH TO DEVELOPING TRANSPORTATION INFRASTRUCTURE PROJECTS IN A CHANGING ENVIRONMENT

Bacher-Gresock, Bethaney Schwarzer, Julianne Siegel

The development of infrastructure facilities can negatively impact critical habitat and essential ecosystems. There are a variety of techniques available to avoid, minimize, and mitigate negative impacts of existing infrastructure as well as future infrastructure development. However, such techniques may not always provide the greatest environmenta...

REGENERATIVE STORMWATER CONVEYANCE (RSC) AS AN INTEGRATED APPROACH TO SUSTAINABLE STORMWATER PLANNING ON LINEAR PROJECTS...

Berg, Joe Underwood, Keith

Stormwater conveyance practices are grounded in industrial design that neglects integration with system processes, economics, and aesthetics. As a result, the greater volume of runoff from impervious surfaces, coupled with smooth and hardened conveyance systems (e.g., pipes and trapezoidal concrete channels), magnifies and transfers energies to the...

A SUMMARY OF THE WILDLIFE LINKAGE AND HIGHWAY SAFETY ASSESSMENT: A PRIORITIZATION AND PLANNING TOOL FOR WESTERN MONTANA

Betsch, Julie K. Olimb, Sarah K. F. Taylor, Dylan W. Williamson, Elizabeth R

Protecting habitat connectivity for wildlife is a management imperative facing agencies and wildlife organizations across the United States. To maintain connectivity and improve highway safety across transportation routes in western Montana, American Wildlands conducted a rapid wildlife linkage and highway safety assessment. This analysis had two p...

RE-EVALUATING THE NEEDS FOR ANIMAL PASSAGES IN ISRAEL: TOWARDS A LONG-TERM MONITORING SCHEME

Achiron-Frumkin, Tamar

Centralized planning framework, accelerating habitat fragmentation and growing awareness to animal-transportation issues in Israel have lead to increased demand for ecological considerations during road construction and maintenance. Several governmental bodies have upgraded their requests regarding fauna passages and monitoring, with substantial bu...

Traffic Volume as a Primary Road Characteristic Impacting Wildlife: A Tool for Land Use and Transportation Planning

Charry, Barbara Jones, Jody

Based on an analysis of current literature, we developed a Traffic Volume Wildlife Tool that identifies different levels of traffic volume as a means to assess risk to various wildlife species groups, including amphibians, reptiles, birds, and mammals. Each level includes an assessment of when impacts to different species groups begin and when they...
