Adequate Septic
In Contact with Mike Dale - Planning Dept
Use Natural Lay of
Land to Reduce Cut and Fill in Roadway
Roundabout Designed to Standards (TFHDC)
Preliminary Site Plan
Geotechnical Analysis
Wildcat Dynamic Cone Penatrometer
Tube Samples (6” &3’)
Laboratory Analysis of Samples Unconfined Compression Test (ASTM D2166)
Atterberg Limits (ASTM D4318)
Particle Size Analysis (ASTM D422)
Assessment of Wastewater Options 3 Options Considered
Conventional Septic System
Presby Treatment System
Wetlands Treatment

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
LID/Conservation Highlights 50% Community
