Fairfax County water plan could block homeowners from adding on

Fairfax County residents looking to build sunrooms, patios and other home additions may have to endure a flood of new regulations that are intended to protect the Chesapeake Bay but could double the cost of construction, officials said.

Virginia law now requires each community to control its flow of excess water from rain storms or snow melts. The rules are intended to limit the amount of pollutants the water can pick up from surfaces like parking lots and carry into the bay, lawmakers said.
