PART III: EVALUATION CRITERIA

1. Project Name: Pensacola Pass, FL, Inlet Management Study

2. Project Description: Pensacola Pass is a large tidal inlet in Escambia County, FL, that connects the Gulf of Mexico with Pensacola Bay (Figure 1). The Pass hosts a Federally-authorized deepwater navigation channel that provides safe passage from the Gulf to the Gulf Intracoastal Waterway (GIWW), Naval Air Station Pensacola (NASP), Pensacola Harbor, and other points in the Pensacola Bay area. The maintained deepwater navigation channel disrupts the natural drift of sand in and across the tidal inlet between Santa Rosa Island and Perdido Key. Periodic maintenance dredging places some portion of the impounded sand back into the littoral system, however, the trapping of sand by the navigation channel does alter the adjacent shorelines for several miles in both directions, inducing erosion due to sand starvation in some areas. The Pass lies between FDEP R-monuments R-67 and R-68.

3. Use of Requested Program Funds: Consistent with the FDEP Strategic Beach Management Plan (SBMP), funds for FY 2018-2019 will be applied for:

 Topographic/ hydrographic survey of 101 R-monument beach profiles (R-001 to R-101, Escambia County, FL),

 Hydrographic survey of the ebb shoal, throat, and flood shoal areas of Pensacola Pass,

 Analyses and development of an inlet management study of Pensacola Pass, which will include analyses of beach, channel, and shoal volume changes over different time periods, compilation and analyses of dredging records, modeling of alongshore transport in the vicinity of the inlet, analysis of sand disposal practices, and the development of a sediment budget for current conditions. Previous investigators have reported upon work at the Pass, including an inlet management study performed by the University of Florida (Browder and Dean, 1999).

 Develop recommendations from the study for maximizing sand bypassing and improving sand management activities at the Pass, to be delivered in the form of a proposed Inlet Management Plan to be presented to the Florida Department of Environmental Protection (FDEP) for consideration for adoption.

No other activities proposed until results of Study are completed.

7. Balancing the Sediment Budget:

Provide a brief description of when the last sediment budget engineering analysis was completed for the inlet and area of inlet influence. Discuss any proposals to update the sediment budget:

In 2008, the Department received an update to the littoral processes associated with the inlet shoal system and the adjacent shorelines. The present proposal includes an update of the inlet sediment budget and the development of an inlet management plan. A plan was last proposed in 1999 (Browder and Dean, 1999, not adopted as an official IMP). This request proposes to conduct a thorough update survey, an update to the inlet sediment budget and the development of a proposed Inlet Management Plan.

What is the annual bypassing objective (cubic yards/year) adopted by the IMP or the SMBP or as determined by a department approved study?

This request proposes to update the sediment budget and determine an appropriate value for the annual bypassing objective. Browder and Dean (1999) suggest that shoaling rates in the inlet may exceed 300,000 cy/yr, while the NET longshore transport in the area might be 70,000 cy/yr. These values need updating. The SBMP for Pensacola Pass cites the same 1999 report and values.

Pensacola Pass, Escambia County, FL olsen associates, inc. FY 2018-2019 Funding Request 3 01 August 2017

Provide the current annual average of bypassed material (cubic yards) since adoption of a bypass objective:

This request proposes to update the sediment budget and update the recent dredging and disposal values. There is no adopted bypass objective as of this writing. Since 2011, approximately 750,000 cy have been dredged from the channel via USACE channel maintenance, with sand placed along the beach, in the nearshore, and within the swash zone of Perdido Key. These values need updating.

Attach an updated list of the annual bypassing volumes (cubic yards/year) for the inlet for the past 10 years (starting from the last calendar year or the most recent calculation).

2011/2012: 520,000 cy dredged 2016: 230,000 cy dredged

750,000 cy dredged and placed on Perdido Key over roughly a 10-yr period, equates to 75,000 cy/yr. This value assumes the placed sand is effectively bypassed (likely not the case). The true bypassed value is likely lower than that. The proposed study intends to refine and update these values.

8. Sand Reaching the Inlet: Provide the current estimated annual quantity of beach quality sand reaching the updrift boundary of the improved jetty or inlet channel:

This request proposes to update the sediment budget and determine an appropriate value for the volume of sand reaching the inlet each year. Browder and Dean (1999) suggest that the value might be on the order of 87,500 cy/yr. This value needs updating.

9. Cost Effective Alternatives: Provide the estimated bypassing shortfall of sand (cubic yards/year) within in the inlet system:

TO BE DETERMINED. Browder and Dean suggest the value could be on the order of 150,000 to 200,000 cy/yr

Provide the increase in annual bypassing of sand (cubic yards/year) proposed for this project:

TO BE DETERMINED. From the discussion above, Browder and Dean suggest the value could be on the order of 125,000 to 200,000 cy/yr (assuming somewhere between 0 and 75,000 cy/yr are effectively bypassed. These values need updating.
