Stormwater Management • Reduces peak flows, and time to peak flows • Increases stormwater quality as pollutants settle out • Designed to accommodate 10 year return period storms • Project Objectives • Draft multiple layouts to accommodate lots ranging from 1 acre estates to 0.1 acre low maintenance lots. • Conduct geotechnical investigation for foundation and stormwater designs • Reduce the impact to the environment through the use of stormwater management • Develop innovative solutions to create a low impact development • Geotechnical Investigation • Soil samples were taken from 6 locations based on SGS soil maps and topography • water content, plasticity, confined compression, and grain size analysis were conducted for each sample • Penetrometer test conducted at each site • Results showed that the soil had suitable Suitable bearing capacity Figure I.3 Intensity Duration Frequency Curve (IDFC) the site • Rain Garden • Provides stormwater detention, increases water quality, and facilitates groundwater recharge • Constructed with a high permeability soil, sand, or gravel • Water storage is provided within the pore spaces Soil Test Sites Paragon Prepared For: Construction • Site Layout • Layout chosen to minimize grading by following existing land contours • Smaller lots located along golf course to maximize views • Estate lots located in a gated community on southern parcel Minerva Engineering Prepared By: Department of Civil Engineering Stephen Rowe, John Kats, Matt Lash, Peter Flynn, Ryan Schipper
