Conventional structural systems do not meet the objectives of environmental stewardship including full use of recycled materials, minimizing labor costs, expedited construction, and a fully recycled system at the end…
The Pagosa skyrocket (Ipomopsis polyantha) is a rare plant, endemic to Mancos shale soils, and found only in and around Pagosa Springs in Archuleta County, Colorado. Plants are between 1…
The southeastern United States is the center of biodiversity for freshwater fishes and mussels in North America. Many of these species are imperiled and one of the leading causes of imperilment…
Assess management efforts to prevent or slow the spread of exotic plants into and away from roadsides. Research should stratify sites based upon ecosystem, soil fertility and time of disturbance.…
Project Description: With culverts installed in numerous locations throughout southern California to allow for hydrological flow under roadways, they also provide the secondary function of vagile species connectivity to habitat…
Background: Natural and engineered dispersion are best management practices (BMPs) designed to receive highway runoff from sheet flow for the purposes of water quality treatment and flow control. These BMPs…
Background: This research proposal seeks to study Portland Cement Pervious Concrete’s (PCPC) ability to remove pollutants, particularly heavy metals, and reduce surface volume flows from highway runoff. This study will…
Research Idea Scope: Background: Petroleum hydrocarbon pollutants are present in stormwater runoff at most transportation facilities, and reducing their levels is a common requirement in National Pollutant Discharge Elimination System…
General Scope of Work: Task 1: Literature Review. Complete a literature review to determine the sources of zinc in highway runoff. The literature review should also attempt to determine if…
Stormwater treatment of bridge deck runoff has always been a tough design challenge. Traditional methods of treating bridge deck runoff suggest piping stormwater off the bridge and treating it on…
