Consideration, discussion and possible approval of the Drainage Advisory Committee's recommendation to reject additional expenditures of 2018 General Obligation Bond, Proposition 6 funds for construction of erosion control improvements on a private pond in the Pembrooke Park subdivision

Background:
Pembrooke Park subdivision is located along the south bank of the East Branch of Haikey Creek. The subdivision has a privately-owned pond that abuts the creek. The pond embankments and surrounding property is experiencing moderately severe erosion. Some of this erosion may have been caused by undermining of a large tree that fell into the creek and forced high waters into the west bank of the pond. In addition, the tree dammed up the creek and was trapping other debris. The fallen tree was located in close proximity to the roadway culvert underneath Olive Avenue. The standing water as a result of the fallen tree was reducing the conveyance capacity of the roadway culvert.
On October 28, 2019, the Drainage Advisory Committee recommended to Council that an amount of $10,000.00 be applied towards the removal of the fallen tree and any subsequent debris that was damming up the creek and creating a potential erosion issue. The recommendation included that any excess funds remaining after the tree and debris removal be applied towards placing riprap along the western embankment of the pond. City Council approved these funds on November 18, 2019.
Tree and debris removal has been completed at a cost of $3,000.00 leaving $7,000.00 remaining for riprap placement. The Pembrooke Park Homeowners Association hired Keithline Engineering Group, PLLC, to design a set of construction documents for erosion control along the western embankment of the pond. The plans were scheduled to open February 15, 2021.
The construction cost estimate is $31,355.00. The portion of the project associated with the riprap is $15,770...
