|Least Environmentally Damaging Practicable Alternative (LEDPA)|
Based upon the Clean Water Act Section 404(b)(1) Guidelines, the LEDPA is the preferred alternative that is least damaging to aquatic resources (i.e., Wetlands and other waters of the U.S.), unless this alternative results in other significant adverse impacts. The evaluation of practicable alternatives must consider the impact to waters of the U.S. that would result from an alternative before compensatory mitigation is considered and requires the selection of an alternative that avoids and minimizes impacts to wetlands and other waters of the U.S. The Section 404(b)(1) Guidelines require that the LEDPA to aquatic resources be chosen unless this alternative results in other significant environmental consequences. Impacts to other resources such as residential and business relocations, historic resources, endangered species, and public community facilities, may be considered in selecting the LEDPA. The selection of a LEDPA also occurs after the public and other parties have had an opportunity to review and comment on alternatives under consideration in an USACE Public Notice or an environmental document. In the Merger Process, the selection of the LEDPA is Concurrence Point 3.
Opening of bids at a specified time on projects that NCDOT has advertised for receipt of bids from contractors. NCDOT normally takes bids on projects on one day each month (third Tuesday).
|Level of Service (LOS)|
A qualitative assessment of a road's operating conditions. It is a standard measurement used by transportation officials which reflects the relative ease of traffic flow on a scale of A to F. LOS A is free-flow with no delays while LOS F is rated congested and significant delays.
A structural BMP device that diffuses storm water flow into sheet flow through buffers for compliance with riparian buffer protection rules.
Logical termini for project development are defined as (1) rational end points for a transportation improvement, and (2) rational end points for a review of the environmental impacts.
|Long-range Transportation Plan (LRTP)|
A document resulting from regional or statewide collaboration and consensus on a region or state's transportation system, and serving as the defining vision for the region's or state's transportation systems and services. In metropolitan areas, the plan indicates all of the transportation improvements anticipated to be funded over the next 20 years. The statewide plan, titled the Long-Range Statewide Multimodal Transportation Plan, establishes a recommended investment scenario.
