[ARCHIVED] December 13, 2019 Drainage Improvement Construction Update

Puddles can be fun if you are 5.. (2)

The following summarizes upcoming Drainage Infrastructure Improvement project work for FY 2019-20:

•    Project Area 11: Nags Head Cove Subdivision in the proximity of Pompano Ct.: This area has experienced standing water due to lack of drainage infrastructure, high groundwater, and no available drainage outlet. Drainage improvements will be complementary to the new multi-use pathway and include the construction of curb and gutter along with a new storm pipe network.   The dual nature of this construction will not only economize construction costs but minimize the disturbance to the public through a condensed construction time period.  Current project status: Permit drawings are in the process of being developed with bids anticipated to be advertised within the next several weeks.  Expected commencement of construction is Winter 2020.

•    Project Area 12: S. Old Oregon Inlet Rd., MP 19.5: This area along S.Old Oregon Inlet Rd. is low-lying and becomes inundated following significant rainfall events. The project goal is to reduce the frequency of flooding in addition to the depth of floodwaters. Scheduled drainage improvements consist of an infiltration trench catchment network along east side of S. Old Oregon Inlet Rd. These efforts will improve effective storage below existing ground level. Current project status: Construction drawings are complete with bids anticipated to be advertised within the next week.  Expected commencement of construction is Winter 2020.

•    Project Area 13: S. Old Oregon Inlet Rd., MP 17.5: Sections of S. Old Oregon Inlet Rd. and the surrounding low-lying areas area frequently flooded following significant rainfall events. The low-lying topography in combination with the lack of a drainage outfall are currently the limiting factors in providing a conventional solution to this issue. Scheduled drainage improvements consist of an infiltration trench catchment network along the east side of S. Old Oregon Inlet Rd. in association with a pump station for downstream conveyance to an infiltration area. The project goal is to reduce floodwater depths and improve dewatering times for localized flooding.  Current project status: Construction drawings are complete with bids anticipated to be advertised within the next week.   Expected commencement of construction is Winter 2020.
