Casey Key couple wins approval to repair collapsed section of retaining wall and deck

This was only the fifth request in Sarasota County history for a Class II Emergency Variance, staff says

It was only the fifth time in Sarasota County history that staff had brought to the County Commission a petition for a Coastal Setback Class II Emergency Variance, Environmental Permitting Manager Howard Berna told the commissioners on Jan. 29.

After hearing from staff and one of the petitioners, plus supporters of the latter’s plans, two of the commissioners almost spoke in unison as they tried to make a motion to approve the request.

“We’re going to fight over you now,” Commissioner Nancy Detert told Joey and Tracie Langston of 2016 Casey Key Road, after Commissioner Alan Maio let her make the motion. Maio seconded it, and it passed unanimously.

As Berna explained to the board, the Langstons were requesting the variance so they could repair the damaged part of a concrete retaining wall and a paver deck on the Gulf side of their property on Casey Key Road. They also planned to connect the wall to the new section of concrete deck slab, using reinforced steel rebars.

Berna reminded the commissioners that a Class II Emergency Variance “is intended to be a rapid response to structures that are at great risk caused by recent storm events.”

The granting of such a variance makes it possible for a property owner to take “temporary storm protection measures,” Berna added.

Last year, he continued, the commissioners granted such a variance to another set of Casey Key Road property owners so they could stabilize a cabana on the shoreline, as it was at risk of collapsing.

Unlike that recent case, he said, “This would not require a regular variance at a later date, because this is replacing what was there.”

Showing the board an aerial image, Berna explained that the Langstons’ property is midway between the Blackburn Point Road Bridge and the Albee Road Bridge.

The Langstons’ house, on the bay side of Casey Key Road, was constructed in 2010, Berna noted. On the west side of the road, the couple has a cabana, the concrete paver deck, a wooden deck and the retaining wall, which dates from the 1970s. Additionally, a dune walkover structure was constructed in 2005 through a process that staff was able to handle on an administrative basis, Berna said.

The retaining wall is only about 83 feet long, he continued, while the Langstons’ shoreline encompasses approximately 200 feet. The rest of the shoreline is natural, Berna added.

In 2018, the Florida Department of Environmental Protection included that section of Casey Key’s beach in its list of critically eroded beaches in the state, Berna pointed out.

Showing the board a series of slides, Berna explained that the retaining wall first began to separate from the concrete slab of the deck. A staff memo in the board’s agenda packet noted that in March 2018, “a strong cold front caused more than 10 ft. of dune erosion at this location.” On July 25, 2018, the Langstons applied for the Class II Emergency Variance, the memo said.

Then, after Hurricane Michael passed through the Gulf last September, Berna told the commissioners, about 48 feet of the northern portion of the concrete retaining wall and a portion of the concrete deck collapsed.

That segment of the retaining wall needs to be rebuilt, he said, and then another section 6 to 7 feet long would be constructed to connect the retaining wall to the deck. About half of the 7.5-foot panels will be buried below the grade, he added.

The new segment of the deck will be a 6-inch slab, he continued, with pavers placed on top.

The wall is approximately 45.3 feet seaward of the county’s Gulf Beach Setback Line (GBSL), Berna noted.

As county staff members have explained in past public hearings, the GBSL is the figurative “line in the sand” beyond which new construction generally is prohibited, so native vegetation can keep the shoreline as stable as possible during storms, protecting construction landward of the GBSL.

The Langstons’ retaining wall is only about 32 feet landward of the Mean High Water Line, Berna continued, which means it likely will be subjected to “further impacts and undermining … if recent erosion trends continue along this shoreline.”

The Mean High Water Line is approximately 79 feet seaward of the edge of Casey Key Road, he added.

On one other note, Berna provided the board members a chart showing sea-turtle nesting data from 2009 through 2018 on the shore at 2016 Casey Key Road. The number of nests ranged from a low of two in 2009 and 2011, up to a high of 21 in 2016. Last year, six nests were recorded.

Berna characterized that as “a fair amount of activity,” telling the commissioners he considered the information “rather important to share with you.”

Finally, Berna explained, before granting a Class II Emergency Variance, the board needs to determine that the proposed action will minimize impacts to the coastal systems. “Should erosion trends continue in this area,” he said, tidal action could result in the scouring of the toe of the retaining wall. That, in turn, could result in adverse impacts on sea turtles and lateral pedestrian access along the beach, he added, as well as possible disruption of the natural movement of sand from north to south on the shoreline.

The petitioners’ view

Speaking for himself and his wife, Joey Langston told the commissioners that he could offer some “funny anecdotes that go along with this storm damage …”

Before the section of wall and deck collapsed, he said, he and his wife “actually had a rather expensive landscaping job done,” involving the planting of native vegetation, especially sea grapes, in an effort to stabilize the beach, he explained. “Within two hours [of the work’s completion,],” he continued, “a storm hit at night. It was like a cartoon: I was standing in the Gulf, throwing plants to my wife … We saved 60 out of 320 plants that had been there less than two hours.”

Rod Jacobson, owner of The Island Building Co. in Nokomis — who has been working with the Langstons on their proposed project — referenced one sea grape on the beach in slides Berna had shown the board. (Structures immediately landward of that plant, Berna told the commissioners, had seemed to weather the storms much better.)

Jacobson added that he has been working on Casey Key projects for the past 26 years. “That sea grape should go into the ‘Sea Grape Hall of Fame’ … because it has helped to minimize erosion so much for so many years.” The plant had been there as long as he could remember, Jacobson added.

“Despite the fact that nature has not smiled on us,” Langston told the board, “we are anxious to get this [damage] repaired. We seek not to add. We seek simply to repair and restore what was there previously.”

“We have a significant investment on Casey Key Road,” Langston added. “We love it there.”

Sarasota County Property Appraiser Office records show that Tracie Langston paid $6.2 million for the property in August 2014. In 2018, the property had a total value of $6,430,700, the records say.

Langston also pointed out that he and his wife had hired Erickson Consulting Engineers of Sarasota to undertake a study of the property. The firm concluded that a 15-year storm could affect Casey Key Road in that area, Langston added. Yet, a 15-year storm, he noted, “seems to come about every 15 months now.”

After two of the Langstons’ Casey Key neighbors voiced support for the Langstons’ petition, Chair Charles Hines closed the public hearing.

Following Commissioner Maio’s seconding of Commissioner Detert’s motion to approve the variance, Maio noted the need for some humor after a long day of agenda items for the board. Referencing Langston’s comments about trying to save the landscaping plantings from a storm, Maio said, “I could imagine, my wife and I, in that situation, [but] there could not be any audio recording of that, with my mouth.”

“Heaven forbid,” he told Langston, “this happens to you again, you need to bring us the video.”
