Before/After
Examples
Egg Harbor, Wisconsin
BEFORE: Low, flat beach with large swash zone.
Rock jetties reduce water movement.
BEFORE: Low, flat beach with large swash zone.
Minimal vegetation to hold sand in place. Waterfowl
loafing helps create environment for bacterial growth.
BEFORE: Low, flat beach with large swash zone.
Large populations of waterfowl consistently
utilizing beach area.
DURING CONSTRUCTION: Beach is nourished to minimize swash zone and
improve infiltration. Native plantings are used to hold sand in place and
discourage waterfowl. Stormwater runoff is treated through infiltration and bioinfiltration prior to entering the sandy beach area.
DURING CONSTRUCTION: Native plantings improve
aesthetics, treat stormwater, and hold sand in place.
Walkways and picnic areas are established throughout
the planting area.
AFTER: Beach is higher and drier as a result of
beach nourishment.
AFTER: Native vegetation assists in holding
sand in place, treating stormwater runoff from
parking lot and nearby roadways, and preventing
waterfowl loafing.
AFTER: Boardwalks and pathways direct
beachgoers to sandy beach area with minimal
disturbance to vegetation.
AFTER: Picnic areas are designated throughout
park/beach area.
