Problem

Mackintosh on the Lake, a home development community in North Carolina, has a large stormwater pond and multiple forebays to handle the community's runoff storage. The emergency spillway allows for excess water to properly drain from the detention pond when the capacity has been exceeded. The spillway was in need of protection in order to control erosion and reduce potential damage to businesses and residences downstream.

Solution

ARMORMAX® Engineered Earth Armoring Solution™ was chosen because it is a soft armoring solution that is easily installed, improves water quality and is resistant to non-hydraulic stresses such as mower and maintenance equipment.
