Brazoria County RESTORE Act Projects
Presentation to Brazoria County Commissioners Court January 25,
2016 Brazoria County Objective
Brazoria County has two projects they are currently developing for
potential funding through the RESTORE Act program. Project 1:
Restoration of the county fishing pier located at Quintana Beach
Project 2: Ecosystem restoration project to reopen of the Mouth of
the San Bernard River to restore the natural flow of the river to
the Gulf of Mexico. Quintana Pier November 2012 May 2014 Project
Scope Brazoria County is seeking a RESTORE Act grant to fund
therenovation of the existing Quintana Pier to include a 200
ft.extension of the pier into the Gulf of Mexico capped with anew
150 ft. T-head.The renovation, new extension and T- head will be
compliant with the Americans with DisabilitiesAct (ADA). Quintana
Pier Background
The current pier was constructed by the county in the 1988
tofacilitate recreation opportunities for county residents and
tourists Length- 240 ft. Width- 10 ft. Elevation- 15 ft. T-head- 58
ft. The pier is constructed on timber piles with a treated lumber
deck and has a lighting system that runs along the pier and T-head.
The current pier is accessible by stairs and a wheel chair ramp but
it isnot 100% ADA compliant. Quintana Pier Actions completed to
date:
Structural assessment of the existing pier is complete Survey of
the land and water side is complete Geotechnical borings on
landside are complete (waterside boring will becompleted during
final design) Conceptual design and project opinion of cost are
complete USACE permit is pending GLO permit has been issued Plan
and Section Views Cost Estimate The cost estimate includes:
Restoration of the existing pier, Extension of the pier 200 ft.
Construct 150 ft. T-head Upgrade and extend electrical lighting
Estimated construction cost is $165 per sq. ft. Total project
opinion of cost approximately- $1.72M Project Benefits Recreation
Educational platform for local schools
Fishing Birdwatching Site seeing Compliments and enhances the
Countys existing Quintana Beach Park Educational platform for local
schools Promotes Tourism Readiness Project planning, is complete,
permitting is underway and final designand construction can be
completed in 7-12 months Projected RESTORE Act funding source- Pot
1 San Bernard River Project Scope Brazoria County is seeking a
RESTORE Act grant to fund an ecosystem restoration project to open
the mouth of the San Bernard River. The proposed project is to
dredge the rivers historical channel to a width and depth that will
enhance river flow, alleviate local flooding, restore normal
drainage conditions to the regional wetlands, and reduce sediment
flow and erosion along the Gulf Intracoastal Waterway. The dredge
material will be used beneficially to counter subsidence and to
restore wetlands within the San Bernard National Wildlife Refugee.
Beach quality material will be beneficially used to nourish the
beach along the refugee. Background In 1929, USACE diverted the
Brazos River around Freeport to reduceflooding and shoaling at Port
Freeport. Today, the mouth of the San Bernard River is heavily
influenced by the newBrazos River delta. The average annual
suspended-sediment yield of the Brazos is the highest of all
riversin Texas, 39 metric tons per square kilometer (Curtis et al.
1973) The river closure is caused by three main factor; Sediment
transfer though the littoral drift from the new delta Reduced flows
down the San Bernard River Gulf wave and tidal forces pushes
material into the mouth In 2009, USACE dredged the mouth open By
Feb 2012, the mouth was again closed due to shoaling History
Bathymetry Change River Flow Data San Bernard River Actions
completed and pending:
Hydrodynamic modeling and alternatives development-complete Team
evaluated six different management options No action Dredging only
Dredging with stabilization- single jetty/groyne Dredging with
stabilization-double jetty Dredging with stabilization- East weir
jetty and west typical jetty Establish a channel to connect Cedar
Lakes to increase the tidal prism Each of these options was
evaluated to maximize channel width, depth and required length for
structural features USACE and GLO permitting is underway Survey is
complete Geotechnical investigations differed until final design
Preliminary project opinion of cost is complete The dredging only
option is estimated at $10.3 M Potential Dredge Channel
Configurations Project Benefits Ecosystem Restoration- Restoring
historical flow enhances over 10,000 acres ofcritical wetlands
habitat Reopens a historical fish pass along the coast Enhances
water quality within the region Reduces the local flood risk and
the navigation hazards along the GIWWassociated with backflow
Reduces sediment transfer and erosion along the GIWW Reestablishes
the historic fish pass Project Benefits Beneficial use of dredge
material
Restore wetlands in San Bernard Wildlife Refugee/Justin Hurst WMA
Counters regional coastal subsidence Beach Nourishment Reintroduces
material to the littoral drift benefiting Matagorda County
Readiness Project Planning is well underway
Final alternative selected summer of 2015 Environmental permitting
-underway Final design and construction to begin upon approval of
the grant Design and construction 12 months Project is supported by
the County, the local community, localindustry, Port Freeport, the
Brazosport Chamber and USACE Potential Restore Act funding sources-
Pot 1 and Pot 2 NRDA grant through TPWD and National Fish and
Wildlife Foundation Grant Applications Due to the State by April
