SUMMARY:
This Section 319 grant project will consist of the final phase of a three-phase construction project to route approximately 760 acres of untreated stormwater runoff to the newly constructed Spanish Trail Retention Pond (phase II) for primary treatment. The new retention pond will discharge the treated stormwater into Gaberonne Swamp to provide enhanced stormwater treatment prior to final discharge into Pensacola Bay and will help restore the sensitive ecology of the Gaberonne Swamp system. The first phase (I), Langley Pond Retrofit, is now completed and consisted of re-vamping the existing stormwater pond at Langley Avenue/Scenic Highway and relocation of an outdated ECUA sanitary-sewer lift station. The second phase (II), Spanish Trail Retention Pond, is also completed and is approximately 8 acres in size and constructed on City (Airport) owned property east of Spanish Trail and south of Avenida de Marina immediately adjacent to Gaberonne swamp. The proposed improvements will meet all applicable standards and specifications for City of Pensacola, Northwest Florida Water Management District (NWFWMD), the Army of Corps of Engineers (ACOE), and the Florida Department of Environmental Protection (FDEP).
