Fort Walton Beach Council agenda — 03-10-09 regular — reading text

Wildlife Service has been approved for $ 25,000, which will be used toward native vegetation. On June 12, 2007, City Council approved funding in the not to exceed amount of 33,000 to complete the engineering, design, and survey work. Subsequently, Goodwyn, Mills and Cawood, Inc. was selected and the design plans and permits are complete. Currently, the project is ready to be advertised for bid solicitation. The bid process will be handled by CBA and Northwest Florida State College staff members with assistance from the City. No City Council action is required at this time. The City's NPDES partners, CBA, and Goodwyn, Mills, and Cawood have prepared the Santa Rosa Sound Ecosystem Restoration update presentation for informational purposes only as an update to the status of the project SubmaujMd ft: Samuel 0.

Proiect Description: The Choctawhatchee Basin Alliance ( CBA) of Okaloosa- Walton College will complete an ecosystem restoration project at Liza Jackson Park in the City of Fort Walton Beach, The project involves restructuring an existing linear stormwater outfall into a vegetated, meandering stream to restore habitat, increase retention, and maximize the filtration of sediments and pollutants. The project will improve treatment ofthe 63 -acre urban watershed that discharges directly into eastern Santa Rosa Sound, a SWIM priority waterbody, and includes a significant public awareness and education component. A large outfall situated on the east perimeter of the park and flows directly to Santa Rosa Sound. The outfall was historically a natural stream that was utilized for stormwater release. The stream" will be narrowed and manipulated to form a meandering pattern with the utilization of an existing natural retention area on the southeast comer of the park as an overflow area. The banks will be planted with native vegetation by volunteers. The existing wetland area along the shore will also be restored via volunteer efforts using appropriate native vegetation acquired from local vendors. This restoration project compliments several other stormwater improvement projects located within the basin. Prior to initiation of construction, the GRANTEE will provide final plan view drawings and permit verification, as indicated under the Deliverables section below. The DISTRICT shall review and approve the final design and project plans to ensure the project is consistent with the awarded grant proposal and provide written approval and/ or offer recommendations for modification. NWFWMD Grant-Funded Activities: Florida Forever capital improvement grant funds may be applied to construction expenses, to include: Restructuring of existing, narrow watercourse through Liza Jackson Park into a meandering stream while utilizing the existing natural retention area. Restoration of natural stream features including removal of non -native and invasive plant species as well as replanting of native vegetation along the stream banks. Construction of an educational kiosk to be located at Liza Jackson Park. Deliverables (Must be complete to receive payment): Final plan view drawings labeling major project components and improvements at appropriate detail.

Background: Gap Creek is a perennial stream that flows through the southern portion of Okaloosa County and the City of Fort Walton Beach. Its headwaters lie within the eastern boundary of Hurlburt Field. From Hurlburt Field, the creek heads east for approximately 2.50 miles where it passes through a culvert under State Road 189 ( Beal Parkway) into Cinco Bayou, which is an arm of the greater Choctawhatchee Bay. Gap Creek has a drainage basin of approximately 2.90 square miles, and its Upper Basin encompasses a mixture of private and government property. The Lower Basin is bounded by Hill Avenue NW on the west and Cinco Bayou on the east and is developed almost to saturation. The Lower Basin is a degraded urban creek area that does not have the flow and storage capacity to adequately transport the extra volume of water created during rain events. As a result, residents of the Lower Basin experience frequent, significant flooding and structural damages. The City's W.E. Combs neighborhood, located on the west side of the Lower Basin, contains mostly older homes situated on off g - rade foundations. These homes are especially vulnerable to soil erosion and foundation undermining from frequent flood events. In an effort to provide relief for these citizens, the City sought to collaborate with other entities concerned with the frequent flooding of the Lower Basin. The City and its partner, Choctawhatchee Basin Alliance (CBA), have met and worked with the Northwest Florida Water Management District NWFWMD), Okaloosa County, the Sylvania Heights Front Porch Florida Community ( SHFPFC), the W.E. Combs Neighborhood Group, the Florida Department of Environmental Protection FDEP), the Three Rivers Resource Conservation and Development Council, and the Okaloosa County School Board. All parties agree that a solution to Gap Creek's flooding issues will be a vital step in improving residents' quality of life. Disgussion: On May 15, 2007, City Council approved a partnership with Okaloosa County to develop a hydrological study of the Gap Creek watershed to develop recommendations for improvements to aid in improving water quality and reducing flooding issues. Okaloosa County was successful in obtaining a grant from the Northwest Florida Water Management District to complete the study. The grant required a 50 percent match, or $ 58,357.00, of which the City was responsible for 30 percent, or $ 17, 600.00, to cover its contribution to the drainage basin. Okaloosa County tasked HDR Engineering, Inc. of Pensacola to complete the Gap Creek Watershed Water Quality Improvement Project. Throughout the project, the City and County provided input to develop the final version of the study report. The final report was submitted by HDR Inc. in November 2008. In the final report, total of 19 retrofit Engineering, a recommendations were suggested by HDR to alleviate the water quality issues in the Gap Creek basin, with six ( 6) of those recommendations also providing water quantity improvements. The estimated construction costs of the recommended improvements range from $8,000 to $533,000. Of the 19 recommended improvements, seven (7) reside within the City limits. Recommendation: No City Council action is required at this time. HDR Engineering, Inc. has prepared the attached Improvement Project for presentation outlining Gap Creek Watershed Water Quality the informational purposes only as an update to the status
