Acceptance of the Drainage Advisory Committee's recommendation to expend 2018 Go Bond, Proposition 6 funds for retaining an engineering consultant to design a set of construction plans to mitigate erosion along Adams Creek adjacent to the Preserve Park Regional Detention Pond (Case No. 24-002)
End
Background:
Erosion is occurring along the north bank of Adams Creek adjacent to Preserve Park Regional Detention Pond. The stream bank is eroding adjacent to the detention pond embankment.
Preserve Park Regional Detention Pond is located North of Albany St (61st St) and west of 37th St (209th St) immediately north of Adams Creek. The park and the pond are owned by the City of Broken Arrow. The regional detention pond was constructed in 2021. The area the regional detention pond serves is just under a square mile. The drainage area for Adams Creek at this point is approximately 7.5 square miles. The fully developed 1% (100-year) flow in Adams Creek is 10,582 cfs and the velocity is 9.7 ft/s. The fully developed 10% (10-year) flow in Adams Creek is 5,643 cfs and the velocity is 8.6 ft/s.
A 30-inch sanitary sewer runs parallel to the detention pond and along/through Adams Creek to the Adams Creek Northwest lift station. A portion of the steel casing over the line is exposed on the creek.
This area flows to Adams Creek.
On January 29, 2024, the Drainage Advisory Committee reviewed and recommended to City Council to approve the request for $50,000.00 in 2018 GO Bond Proposition 6 funds for obtaining a design consultant to design a set of construction plans to mitigate erosion along Adams Creek adjacent to the Preserve Park Regional Detention Facility.
Cost: $50,000.00
