Progress Report: Village's Beach Restoration Project

Posted: Thursday, April 20, 2017 1:30 pm

 

Stage 1 of the beach renourishment project was completed on Wednesday, April 19, 2017. 16,138 tons of sand have been placed as of yesterday (4/19); this quantity is approximately 44 percent of the total estimated tonnage for the project (36,400 tons). For a description of the work, scroll down to to the Section labeled "Project Overview".

Preparations for and implementation of Stage 2, plus key information for residents, are outlined below. 

  • Crews for Eastman Aggregate Enterprises (the Contractor) will now work South of the staging area in front of the Oceana condo (Figure 1). Vehicles and equipment will move along the marked hauling area for the next few weeks (Figure 2).
  • Work hours for sand delivery by trucks along Crandon Boulevard to Sonesta Drive to the beach (Figure 3) and distribution on the beach are from 7:00 a.m. to 5:00 p.m. Monday-Friday. Preparation/survey work may start at 6:00 a.m.
  • The North beach access path at Oceana will be closed for the duration of the project for equipment staging. The South beach access path will be closed daily during work hours but will reopen after 5:00 p.m. on weekdays and will be open on weekends .
  • Eastman is increasing truck deliveries this week to approximately 150 trucks per day with the loop road operational now almost a week..
  • The progression of Stage 2 work has changed: Eastman will now haul sand all the way to the south end of the project (in front of the Towers) for placement, and then work north as templates are filled and closed out. Some of the fill sections are narrow and this change in work plan will facilitate construction. Project officials are conducting volume checks on the tonnage compared to placement volume for fill sections.
  • Eastman has reviewed progress after the first weeks of construction and anticipates sand placement completion around May 6.
  • Coordination is ongoing with DERM and other environmental agencies to continue work into marine turtle nesting season that begind May 1.
  • Should you have questions or comments, please contact Police Chief Charles Press, the Village’s spokesman for the project, at (305) 579-0801.

Project Overview 

Preparations and staging of equipment for a beach nourishment project to add 19,000 cubic yards of sand to approximately 6,000 linear feet of Village shoreline began on Monday, April 3, 2017. Beach access paths North and South of the Oceana condo provide entry to and exit from the beach for Eastman Aggregate Enterprises, the contractor, during the project. Trucks began to deliver sand mined in Central Florida on Thursday, April 6. They use the North pathway from Sonesta Road to enter the beach, dump sand, exit the beach via the South pathway and return to Sonesta Drive via Atlantic Road. Other equipment is used to transport and grade the new sand northwards and southwards along the beach. Work is expected to end in the first to second week of May, weather permitting. Since May 1 is start of marine turtle nesting season, Miami-Dade County’s marine turtle expert will monitor the beach before work begins for nests and mitigate any that are found while the project is underway.

 

Work hours for sand delivery and distribution on the beach are from 7:00 a.m. to 5:00 p.m. Monday-Friday. Preparation/survey work may start at 6:00 a.m.

 

Residents are advised to expect the following during the project:

  • The North beach access path at Oceana will be closed for the duration of the project for equipment staging (Figure 1).
  • The South beach access path will be closed daily during work hours but will reopen after 5:00 p.m. on weekdays and will be open on weekends.
  • Work crews and heavy equipment (dump trucks, bulldozers, excavators, auxiliary vehicles) will be on the beach near Oceana and where sand distribution is occurring. A clearly designated two-way haul road, delineated by signs and monitored by flagmen, will accommodate the heavy equipment used to move and grade the sand (Figure 2).
  • An ATV pilot vehicle will drive in front of dump trucks hauling sand along the beach.
  • Beach users may be asked to relocate or leave the section of the beach within the active work area.
  • Expect extra traffic along southbound and northbound Crandon Boulevard, Sonesta Drive and Atlantic Road.

The following will occur on Monday, April 3:

  • Both North and South beach paths will be closed.
  • 4" thick rubber mats will be laid on the beach access paths for protection.
  • A Maintenance of Traffic (MOT) plan will be implemented along Crandon Boulevard, Sonesta Drive, East Heather Drive, the beach access paths and along the beach in front of Oceana.
  • Heavy equipment needed to move, spread and grade sand along the beach will be staged along the North pathway.
  • Sand leveling in front of Oceana may occur to prepare a path for dump trucks to enter, traverse and exit the beach.

The following will occur from Thursday, April 6, through project completion:

  • Approximately 150 trucks per day will enter the Village starting at 7:00 a.m. to deliver sand and travel along Crandon Boulevard. Trucks will queue at Calusa Park as necessary. The deliveries will ramp up on April 4 and be in full operation on April 5.
  • According to the MOT, the trucks will deliver the sand using Sonesta Drive and exit back to via Atlantic Road and Sonesta Drive.
  • Stage 1 work is estimated to last one week, weather permitting. Sand will be stockpiled at the end of the North beach path and distributed northward to the Village boundary at Crandon Park.
  • Stage 2 work is estimated to last 3-4 weeks, weather permitting. The stockpile area will be moved to the end of the South beach path and sand distributed southward to the Village boundary with Bill Baggs Cape Florida State Park.
  • The North beach access path at Oceana will be closed for the duration of the project for equipment staging (Figure 1). The South beach access path will be closed daily during work hours but will reopen after 5:00 p.m. on weekdays and will be open on weekends.
  • Eastman personnel will perform daily turbidity (water clarity) monitoring, vibration control and monitoring, geotechnical testing and post-surveying of beach sections as they are completed.
  • Demobilization is expected in late April into first week of May. This includes all equipment, mats and access area items, and MOT signage.

Eastman Aggregates will have Project Managers on site every day. EAC Engineering and Moffat & Nichols staff will act as the Owner's Representative Project Manager for the Village to monitor progress, and Village staff will be on site as needed.
