This project is for emergency repairs to the shoreline at Grand Caribe Shoreline Park. District staff was notified of a main irrigation line break at south Grand Caribe (in the natural shoreline park) that occurred over the weekend (January 6 and 7, 2024). This break has resulted in significant scouring of the shoreline, exposed irrigation pipes, and presents an immediate need for action to protect the natural shoreline. Compounding the issue, the region is experiencing King Tides this week, which will exacerbate the erosion. High tides on Thursday, January 11, and Friday, January 12, 2024, will be approximately 7.15 feet in the morning, draining out to a negative tide in the afternoon.
District staff evaluated the conditions and determined a temporary solution, which would include:
• Install temporary fence at the top of the scoured edge for pedestrian/public safety.
• Disconnect, remove and/or abandon in-place irrigation lines on the southern portion of Grand Caribe. At this time, it has been determined that irrigation is not critical in this area.
• At present time, it is anticipated that 240 burlap sandbags (14-inches-by-26 inches in size), each filled with 35 to 40 pounds of sand (1/2- to 2/3-full) will be arranged along 12 linear feet (NOM) of the eroded bluff. The bags will be stacked six feet high (NOM) against the eroded material and the remaining shoreline bluff.
• District General Services will coordinate and implement the sandbag installation, pursuant to the specifications provided above.
• Coordinate materials and method for deployment of sandbags.
• Deploy sandbags, anticipated to be completed by Wednesday, January 10, 2024, pending direction provided by District Engineering.
• Monitoring the site for any further irrigation line breaks, scouring of the shoreline, and environmental or public safety hazards.
Due to its nature and limited scope, construction of the proposed project would generate a minor amount of vehicle trips and would require limited use of equipment. Therefore, impacts related to air quality, greenhouse gas emissions, and transportation and traffic are not anticipated to occur. Furthermore, the Applicant would be responsible for complying with all applicable federal, state, and local laws regarding construction demolition debris, hazards and hazardous materials, and stormwater.
