Hydraulics and Hydrology

Design for 100-yr flood Route stormwater

through wetlands Size pipes to control

flooding Design water quality

trenches Promote natural

overland flow

Existing vs Proposed 100-year Storm Routing

Wetlands Treat 170 acres Design wet pond to

allow for sediment settling/quality volume

Research vegetation for the wetlands

Design outlet structure that controls 100-year flood

Erosion Control Plan

Minimize sediment runoff into Miller Ditch

Minimize cut and fill on-site: 680cy cut

Reduce soil that leave site via truck tires
