Sub-Basin C-I and C-2 will discharge developed runoff to existing Shoshone Street. The roadside
swale in Shoshone is adequate to convey this runoff.

Sub-Basin D-I will discharge runoff as sheet flow to unplatted property in Elbert County.

The proposed Fawn Valley subdivision primarily consists of residential lots averaging 12,700 S.F.,
a 1.7 acre multi-family site, a proposed park, and public roads as shown on the drainage plan. The
public roads are to be asphalt surface with roadside ditches to control runoff. Overlot grading will
convey surface runoff to the roadside ditches or the existing grass-lined swale.

The Drainage Plan in the back pocket indicates proposed routing of storm water runoff. Roadside
swales will be necessary to convey runoff to culverts. Culverts will be located at intersections,
thereby discharging into public rights-of-way. Building sites shall be graded to direct flows away
from structures and toward side lot lines and streets. Culvert sizing is detailed in the Appendix -
HydrologiclHydraulic Calculations - Culvert Sub-Basins.

FLOOD HAZARD AREAS
The grass-lined channel through Fawn Valley will be subject to inundation by a IOO-year storm.
This channel will remain in the previously platted drainage tract and no house construction is
proposed in this tract. Individual homebuilders will not be permitted to construct improvements
within the drainage easements as designated on the recorded plat.

Individual homebuilders, in all cases, should consider the drainage pattern of each lot. Elevating

finish floors a minimum of I-foot above the surrounding ground is a recommended practice.
