Potomac Conservancy (Washington, D.C.), Friends of the Rappahannock (Fredericksburg, Va.), and The James River Association (Richmond, Va.) are hosting a low-impact design (LID) competition that challenges developers to find low-cost solutions to achieving pre-development hydrology. Development categories include suburban mixed use, urban infill, and green roadway. A total $15,000 will be awarded to the winner in each category. The design submission period closes Feb. 17. The Water Environment Federation (Alexandria, Va.) will help promote this event to illustrate the advantages of implementing LID practices.   Read more.
