Hanes Lake —Phase 2 Pfafftown, NC
Narrative
Clayton Properties Group, Inc plans to construct 182 homes in Phase 2. Stormwater runoff will be treated
for quantity by utilizing underground stormtech chambers for detention. Likewise, the stormwater will be
treated for quality in the attached downslope bayfilter devices. Seven permanent engineered stormwater
control measures (SCMs 1,2,3,4,5,E & 7) have been designed for Phase 2 to ensure the stormwater runoff is
adequately treated. Stormwater runoff will also be treated with vegetated swales that have a base width of
2 feet and side slopes of 3H:1V. Channel calculations have been performed for these swales to ensure
these measures are stable during a ten year storm event.
