Approval of and authorization to execute Agreement for Professional Consulting Services with Freese and Nichols for the design of retaining wall improvements holding back a private pond along Aspen Avenue between New Orleans Street and Florence Street (Project Number (SW25070)
End
Background:
The proposed project is to investigate and design improvements to the City owned retaining wall that holds back an existing private pond on Aspen Avenue between New Orleans Street and Florence Street.
Staff investigated the site and found that the slope behind the wall was highly saturated and has started sloughing off into the pond. An existing sheet pile wall is approximately 2 ft behind the retaining wall and installed at the same time as the wall. City staff believes the sheet pile wall could be damaged or corroded causing the leaking at the base of the retaining wall.
The water and sediment on the sidewalk and road could create a slip hazard for the public, especially during winter months. This area flows into the Aspen Creek watershed.
On November 19th, 2024, Council approved the Drainage Advisory Committee’s recommendation to approve the request to use $100,000.00 of the 2018 General Obligation Bond, Proposition 6 funds to hire a consultant to engineer drainage improvements to the retaining wall.
Cost: $74,560.00
Funding Source: 2018 General Obligation Bond, Proposition 6
