Location: E Main Street at Colchester (SE
Typology: Detention Pond Pocket Parks
Project Type: County
Description of Retrofit :
Excavat ion of exist ing pr ivate parcel to create a sur face detent ion
faci l i ty that can funct ion as publ ic open space dur ing the dry season.
The depth of the adjacent storm dra in inf rast ructure requi res an up to
10-foot excavat ion to provide f low control wi thou t backwater ing the
exist ing publ ic storm dra in system. The bottom of the detent ion faci l i ty
may be designed to provide water qual i ty t reatment for low f lows pr ior
to discharge. Project provides f low control as an of f- l ine system.
Addit ional Benefit:
Communi ty - New downtown publ ic open space to f aci l i ta te•
communi ty gather ing and events
Educat ion - Highly v is ible opportuni ty to edu cate publ ic on impacts•
of urban stormwater runoff
Construction Elements (does not include soft costs) :
Costs include:•
excavat ion and haul-
reta ining wal ls and seat wal ls for per imeter of faci l i ty-
storm dra in inf rast ructure and f low control-
hardscape, landscape and s i te furnishings-
