Resiliency project plans to be further discussed

Resiliency project plans to be further discussed

BRADENTON BEACH – One resident’s concerns about a proposed resiliency project garnered enough interest from Community Redevelopment Agency (CRA) members to seek an additional plans review.

After resident and board member David Bell presented his concerns and suggested alterations to the city’s plans during a Dec. 7 meeting, CRA member John Chappie suggested asking ESA Senior Environmental Scientist Brett Solomon to appear before the board in January or February to review the plans and address those concerns. The board supported that suggestion.

“This is one of our big projects for resiliency and we want to do right,” Chappie said.

CRA Chair Ralph Cole agreed and said it’s important to consider the potential impacts to the property owners along Bay Drive South.

The plans

The plans propose using the city-controlled rights of way between the bay and the eastern edge of Bay Drive South pavement from Fifth Street South to Third Street South as well as the Bridge Tender Inn shoreline property owned by Fred Bartizal to construct a 3-4-foot-high resiliency barrier from the Bridge Street Pier boardwalk to the corner of Fifth Street South. The sand-covered rock riprap barrier is designed to prevent rising bay waters from spilling over onto roadways and residential and commercial properties.

The existing rock and sand barrier along the Bridge Tender Inn shoreline would be raised and expanded. A new sand and rock resiliency barrier would also be constructed, extending from Third Street South to Fifth Street South and covered with an elevated walkway topped with semi-permeable pavers.

The plans also propose additional marsh grass and mangrove plantings along the shoreline and the installation of oyster bags and reef balls offshore of the existing rock riprap barrier near the clocktower and pier boardwalk to help dissipate waves.

Suggested modifications

“We haven’t talked much about the resiliency project since we saw the 60 % plans (in March). Now that we’re at 100% on those plans, I think it’s time that we take a deep dive into what’s going on there so we’re all on the same page,” Bell said. Bell and his wife, Mary, own and reside in one of the Old Bridge Village condos located along the west side of Bay Drive South.

As a retired landscape architect, he also expressed concerns about existing mangroves potentially being removed to accommodate the walkway.

“The plans say no mangroves would be removed, but the drawings and the profiles don’t show it that way. They show about a third to half the mangroves being removed and all the trees along Bay Drive South would go also,” he said.

To further illustrate his point, Bell temporarily placed orange flagging tape in the existing mangrove trees to illustrate where he believes the project impacts would occur. He encouraged the other CRA members to visit that area to see for themselves.

“One thing we definitely learned from Hurricane Ian is that mangroves provide their own resiliency. We also know that sidewalks don’t provide resiliency. So, our tradeoff here is that we’re getting rid of the natural resiliency that we have in that area to put in a sidewalk that has no resiliency whatsoever. In my mind, that’s not a very good trade-off,” Bell said.

Perry said ESA’s plans must account for any impacts to the existing mangrove trees and other plants currently located in the proposed project areas.

“It will be in the permit language, saying you may not remove mangroves. If they’re removed, I would be absolutely shocked,” Perry said.

She noted a FDEP representative walked the proposed project area and was comfortable with the plans.

Bell presented some recommendations for the CRA members to consider, including elimination of the plan elements north of Third Street South because of the existing higher elevations that exist there and focusing solely on the areas between Third Street South and Fifth Street South.

“Anything north of that is already out of the area of risk. The reason for this resiliency project – between Third and Fifth anyway – is so that we can keep Bay Drive South open because that’s a major access to and from Bridge Street,” Bell said.

He also suggested eliminating the elevated walkway to preserve the existing mangroves and said, “It really doesn’t serve a purpose for resiliency,” and recommended having a landscape architect redesign the barrier’s appearance to further enhance its scenic qualities while preserving the existing trees and plants.

Perry said some of Bell’s suggestions could likely be addressed without triggering a formal amendment to the FDEP permit but removing the proposed plan elements north of Third Street South would require a require a permitting amendment.

Chappie noted the resiliency project plans were discussed and public input was received during multiple public meetings, including an onsite public meeting in February. During some of those previous meetings, city officials stated the proposed barrier and walkway would not impede any dock access along that shoreline.

In response to Bell’s suggestion to remove the northern areas from the plans, Chappie said, “Holistically, it’s all part of the same project. That’s the way we chose to include that whole section, from Fifth all the way and around the boardwalk area.”

City officials hope to secure state funds in 2023 for the construction of a currently unfunded resiliency project along Bay Drive South.

Using a $92,433 resiliency grant from the Florida Department of Environmental Protection (FDEP), Tampa-based Environmental Science Associates (ESA) engineered the project, designed to lessen the impacts of rising tides, king tides, storm surge and sea level rise along Bay Drive South. Completed in August, the plans now await the FDEP permitting approval that will allow City Attorney Ricinda Perry and ESA to pursue the additional resiliency grants needed for construction.

Neither the city commission nor the CRA currently has any funds budgeted for the project which to date has no estimated cost or anticipated construction timeline.

BRADENTON BEACH – City officials do not support a barrier wall being included in the plans for a potential living shoreline/shoreline resiliency project along Bay Drive South.

On Thursday, Jan. 6, the city commission voted 5-0 in favor of accepting the revised 30% completed engineering plans presented by the Tampa-based Environmental Science Associates (ESA) firm.

The plans presented Thursday evening included revisions made as a result of the Community Redevelopment Agency (CRA) discussion that took place the day before. During both meetings, the plans were presented during a videoconference with ESA representatives Brett Solomon, Bryan Flynn and Tom Ries.

The living shoreline/shoreline resiliency engineering plans are being funded by a $92,433 grant from the Florida Department of Environmental Protection. The grant only covers engineering and design costs and does not include additional funds for the actual construction of a living shoreline/shoreline resiliency project, and no city or CRA funds are currently budgeted for such a project.

CRA discussion

The plans presented to the CRA members on Wednesday originally referenced a barrier wall to be installed along a portion of the project area that extends along the eastern side of Bay Drive South, from Bridge Street to Fifth Street South and including the area near the Bridge Street Pier and city-owned dinghy dock.

The engineering plans also propose the use of natural fill materials, mangroves and other plants, sloped earthen berms, concrete reef balls, oyster bags, bio logs and other onshore and offshore materials that could help make the Bay Drive South shoreline more resilient to future sea-level rise and rising tides.

The plans are based on the National Oceanic and Atmospheric Administration (NOAA) projection that sea-level rise is expected to increase by approximately 4.5 feet by 2050.

Flynn said the southern portion of the Bay Drive South shoreline currently has a 2-3 foot ground elevation and the elevation increases to 5-6 feet toward the northern end of the street. He said the goal is to get consistent elevation of greater than 5 feet along that entire shoreline to combat sea-level rise and increase shoreline resiliency.

Flynn said off-shore reef balls and oyster domes or oyster bags would help dissipate wave energy before the waves reach the plants, berms and other onshore elements.

The seven-member CRA board that includes all five city commissioners and two non-commissioners made it clear they did not support a concrete wall being included in the project.

CRA Chair Ralph Cole said, “That has been such a natural beachline for such a long time and it has been beat down by erosion. When man gets in and makes walls and does a lot of stuff I don’t think it does as good as just helping out Mother Nature and maybe pushing some fill back in there and some natural grass or whatever.”

Cole also expressed concerns about the maintenance requirements associated with a concrete wall that may eventually require replacement.

CRA member David Bell lives in the Old Bridge Village condominiums located along the western side of Bay Drive South.

“I think there’s going to be a lot of resistance to the wall,” he said.

CRA member Jan Vosburgh agreed.

Bell also expressed concerns about a solid wall retaining rainwater on the landward side and preventing that water from dispersing into Sarasota Bay. He also questioned whether the offshore reef balls would be visible during low tides.

In addition to the aesthetics of a shoreline wall, the CRA members expressed concerns about obstructing property owners’ existing views and access to their private docks. CRA member Jake Spooner noted most of the shoreline property being discussed is privately owned. It was also noted that the Bay Drive South rights of way are owned and controlled by the city.

Solomon said ESA representatives could engage in on-site meetings with potentially impacted property owners. Those meetings are to be coordinated by the city clerk’s office.

In response to the wall concerns, Ries referenced an illustration that shows how an earthen berm can be used to disguise a concrete storm wall contained within, with the top of the wall serving as a raised sidewalk. He said such a berm would not need to be more than 3 feet above the existing ground elevation.

“Three feet high is not going to block your view. We want this to be as natural as possible, but in some locations we’re constrained by space. We are trying to get away from seawalls. We want something that truly has resiliency and will work with the nature we have,” Ries said.

As to whether to continue to engineering process, Cole said, “If it’s a grant, it’s free money to get it designed. We’re not obligated to carry that out.”

City Attorney Ricinda Perry noted additional project-related grants may be easier to obtain when associated with a pre-designed shovel-ready project.

CRA member John Chappie said the goal is to create a long-term plan that can be implanted in phases as funds becomes available.

“This is a long-term commitment to get to where we want to be five, 10, 15, 20, 30 years down the road,” Chappie said.

The CRA members unanimously supported moving forward with the engineering plans to be revised based on the input provided during Wednesday’s meeting.

Commission discussion

The revised design options presented to the city commission Thursday evening still reference earthen berms but no longer reference a shoreline wall.

In response to a question from Spooner, Flynn clarified that the offshore oyster bags would be comprised of discarded oyster shells and would not contain live oysters but would help create reef habitats for oysters and other marine life.

During public comment, Old Bridge Village resident and board of directors member Bruce Herard thanked the mayor and commission for pursuing the shoreline resiliency project.

Herard said during a tropical storm in 2020 he sat in his home watching the water rise and the waves wash over Bay Drive South.

“It was the waves that were really frightening in terms of what might ultimately happen to our property. The water came right up to the lip of my garage but didn’t enter. That causes you to understand that we have a real issue. I don’t want my view screwed up, but on the other hand I want my building to not be flooded,” Herard said.

The 60% completed engineering plans are due Feb. 8 and the 100% completed plans are due April 29.
