Consideration, discussion and possible approval to execute an agreement between the City of Broken Arrow and Rushbrooke South Homeowners’ Association, Inc. concerning the construction of certain specific drainage improvements to the east branch of Haikey Creek
End
Background:
Rushbrooke is a residential subdivision situated about one-quarter mile north of New Orleans Street (101st Street South) and immediately east of Olive Avenue (129th E. Ave.). The east branch of Haikey Creek runs through the subdivision. The portion of the creek that runs through the entire subdivision was placed in a platted drainage easement and is kept as a greenbelt for the residents. The Rushbrooke South Homeowners’ Association (HOA) owns and, therefore, is responsible to maintain that portion of the creek that is in the easement.
The creek, itself, has several switchback (near 90-degree bends) turns that over the years have begun to erode several of the stream banks. Some residential dwellings as well as public and private utilities are endangered due to this continued erosion. The HOA has sought help from the private construction community, but has had difficulty in securing enough funds to perform the necessary work as well as has had extreme difficulty getting construction companies interested in this type of construction work.
The HOA reached out to the City a few years ago and requested assistance. On two (2) separate occasions, the HOA submitted a Flood-Prone Property Transfer application in accordance with the request for the City to take over the ownership of the floodplain. The first request was denied and the HOA withdrew the second request once staff and the HOA developed a better approach to address the issues.
Last year, the City of Broken Arrow and the HOA discussed an alternative that would help mitigate the effects of the flow through the creek and potentially significantly reduce the erosion in the most critical location. With the support of city administration, staff developed an approach to construct a straight pilot channel to better facilitate less turbulent flow and eliminate one of the more significant bends in the creek thereby reducing the impact and energy dissipation that is occurring at the most critical location along the creek. This approach was discussed in an on-site meeting with the United States Army Corps of Engineers (USACE). At this juncture, the USACE is agreeable to the approach.
In an effort to significantly reduce the erosion and prevent an imminent danger to a residential home that is current situated on the creek bank, the staff is proposing to partner with the HOA in order to expedite this effort and safeguard and protect against the impending danger that is occurring. The City and the HOA have agreed to a partnership in which the HOA will pay for the construction of the channel, erosion protection, temporary construction easements and incidental construction costs while the City through force labor will construct the project. Staff expects the work to take less than 30 days.
Staff recommends approval and authorization of the agreement.
Cost: $23,000 for materials (to be reimbursed by the Rushbrooke South HOA)
Funding Source: Existing payroll accounts for labor
