In 2013, under CGA’s Continuing Professional Services Contract with The City of Oakland Park, CGA was assigned a Work Authorization for consultant services to design a drainage pump station and drainage conveyance system improvements for the Lloyd Estates neighborhood. The Lloyd Estates neighborhood had a history of flooding problems, caused by undersized and/or damaged underground storm drainage collection systems and poorly graded and silted above ground swales. The existing area experienced frequent flood conditions even at low-intensity rain events due to limited discharge capacity and high tail water conditions downstream of the Sleepy River. The scope of work, led by David Stambaugh, PE, included civil engineering design, surveying, project management, electrical engineering design, structural engineering, landscape architectural and environmental services. In order to mitigate the neighborhoods flooding issues, the design incorporated extensive drainage improvements, water main relocation, milling and resurfacing of the roadway and the construction of a drainage pump station with a bio-swale designed by our Landscape Architectural and Environmental Department.
The design for the site, despite its size, was envisioned to have a high social impact, as it will be of a high design quality and will include a boardwalk with Folia® educational signage, unique paving design, furnishings for passive uses, native landscaping, branding signage with character lighting design, security features, and the inclusion of a transit bus bay. Following the successful design and approval by City Staff and the Authorities Having Jurisdiction (AHJ), the project was awarded to the contractor, Condotte-Kailas, JV. In May 2015, construction broke ground with CGA providing the construction inspection services. One of the most challenging components of the project was the location of the pump station; in a residential neighborhood and drainage conveyance system improvements that took place near an elementary school. Due to limited space available at the location of the proposed pump station, the City acquired property adjacent to the Sleepy River for the pump station that provided an opportunity for the bioswale and other property enhancements. Construction was completed in March of 2017 with the pump station now fully operational.
The project included a $5.4 million grant from FEMA under the Hazard Mitigation Grant Program a result of Hurricane Wilma. CGA assisted the City with identifying the funding opportunity and with successfully completing the application process.
