OPERATIONS & MAINTENANCE INSTRUCTIONS

FOR THE

CRYSTAL BEACH PARK

STORMWATER MANAGEMENT SYSTEM

I. GENERAL:

Stormwater Management Systems require periodic maintenance to ensure that the facilities function as designed.

II. FACILITY OPERATION

This facility is located within the MS4 limits of the City of Destin and was confirmed to fall under their responsibility by City Engineer Robert Tomasek, PE. Stormwater systems normally do not require any kind of operational tasks. Most systems function by the force of gravity. The facility for this site consists of two infiltration basins with appurtenant inlets and piping for stormwater runoff collection and conveyance. Based on the expected land use, it is possible that fats, oils, and greases (FOG) maybe collected by the stormwater system. These shall be trapped by the ADS baffle/”flamp” and cleaned during inspection as part of regular maintenance.

III. FACILITY COMPONENTS & MAINTENANCE

A full component list is included at the end of this O&M Plan. Facilities within this project which will require maintenance include the following:

1. Underground storm retention chambers

2. Inlets and piping systems

A. Underground Storm Detention Chambers

1. Inspection and Maintenance for all isolator plus rows

a. Remove cover from structure at upstream end of isolator row plus.

b. Using a flashlight, inspect down the isolator row plus for visual inspection of sediment levels.

i. Mirrors on poles and cameras may be used to avoid confined space entry.

ii. Follow all OSHA regulations for confined space entry into the manhole.

iii. Inspector to inspect for (FOG) buildup in the ADS baffle/”flamp”

c. If sediment buildup is at, or above 3”, cleanout the isolator row plus using the jetvac process.

i. Use a fixed culvert cleaning nozzle with rear facing spread of 45” or more.

ii. Apply multiple passes of the jetvac until backflush water is clean.

iii. Vacuum the structure sump as required to remove sediment.

d. Replace manhole lid and record observations and actions performed.

B. Inlets and Piping Systems

1. Regular Maintenance

a. Keep inlets and the surrounding drainage area clean and free of any trash and debris which may degrade the system.

b. Following rainfall events, inspect drainage structures and note any standing water inside structures which may indicate a blockage within the drainage system.

2. Restoration

a. When a blockage within the drainage system is apparent, inspect the pipes and structures by visual inspection, snaking or video camera, whichever is appropriate.

b. Remove any blockage using a pressure water system.

c. Remove all soil and debris from the bottom of inlets.

d. Repair failures in the drainage structures or pipe network. Depressed areas in the ground above the pipe network or adjacent to drainage structures may indicate possible failures in the drainage system.

IV. INSPECTION

A. Reporting

Regular inspection of the stormwater management system shall be performed by a registered professional as outlined in these instructions and required by the rules and permit governing the operation of the stormwater management facility. A report describing the results of inspections and certifying that the system is operating as designed and permitted, must be filed with the FDEP within 30 days after the inspection. In the event of a system failure, a report shall be submitted to the FDEP within 30 days of the failure.

SPECIAL PERMIT CONDITIONS:

1. Prior to commencement of construction activity authorized by this permit, a preconstruction conference shall be held at the site among the contractor, the owner or authorized agent, and a staff representative of the Department to establish an understanding among the parties as to the items specified in the special and general conditions of the permit. The proposed locations of the structures shall be staked out for the conference. Contact Marina Foote at (850) 519-0954 or email at marina.foote@floridadep.gov to schedule a conference.

2. Prior to commencement of construction activity authorized by this permit, a temporary construction fence shall be erected along the perimeter of the permitted activity. The fence shall remain in place until the construction authorized by this permit is complete. The optimum siting of the construction fence shall be determined during the preconstruction conference by the staff representative so as to provide maximum protection to the existing native vegetation and dune features located on the site.

3. All sandy material excavated seaward of the control line shall be maintained on site seaward of the control line.

4. Any imported fill material shall be obtained from a source landward of the control line. All fill material

(both excavated from the site and imported) shall consist of sand which is similar to that already on the site in both grain size and coloration and shall meet the requirements of Rule 62B-33.005(7), F.A.C.

This fill material shall be free of construction debris, rocks, or other foreign matter. A sample of the sand shall be provided to the staff representative during the preconstruction conference.

5. Plantings shall conform to the approved planting plan. Removal of invasive plant species and landscape and dune enhancement plant installation shall not cause the removal of existing salt-tolerant native vegetation.

6. No construction, operation, transportation, or storage of equipment or materials is authorized during May 1 through October 31 on any part of the sandy beach or on or seaward of the frontal dune.

7. All activity shall be confined to daylight hours. No temporary lighting of the construction area is authorized at any time during the marine turtle nesting season.

8. All activities shall avoid marked marine turtle nests including those that may be on the beach before or after the marine turtle nesting season. Any impacts to nests that may have inadvertently occurred or if a marine turtle nest is exposed, or a dead, injured, or sick marine turtle is discovered, the Permittee shall ensure that the Marine Turtle Permit Holder be notified immediately such that appropriate conservation measures can be taken. Within 24 hours of any such occurrence, the Permittee shall submit a report detailing the incident (e.g., date, time, permit number, location, photos, contact information, incident and response descriptions) to the FWC at MarineTurtle@MyFWC.com.

9. All debris (including rocks, sandbags, construction materials, etc.) shall be removed and disposed of in a location landward of the Coastal Construction Control Line. All temporary disturbances in the sand (including, but not limited to, ruts, depressions, mounds, etc.) resulting from work activities shall be filled in and raked smooth after project completion.

10. The dune walkover shall be set at a minimum elevation for stringers and cross members to be installed without requiring excavation of existing dune topography. Width of the walkover deck shall not exceed 6 feet. Posts for the walkover structure shall not be greater than 6 inches wide or 6 inches in diameter, must be embedded a minimum of 5 feet and shall not be encased in concrete. The structure shall be designed to minimize debris generation from pickets and other non-structural members. Walkovers shall extend at least up to the existing line of vegetation but not farther than 10 feet seaward of the vegetation.

The optimum siting of the walkover structure shall be determined by the staff representative during the preconstruction conference to provide maximum protection to the existing dune topography and vegetation located on the site.

11. To reduce the risk of marine turtle entrapment, walkover structures shall have three (3) feet of vertical clearance beneath them and at least five (5) feet of horizontal clearance where they meet the beach. The vertical clearances include support bracing, as well as stairs and ramps. The horizontal clearances include between support pilings, and between stair blocking and pilings. Where these clearances cannot be met (such as under the stairs or ramp), blocking with appropriate materials shall be used to preclude marine turtle, including hatchling, access. The blocking material shall be buried a minimum of one foot into the sand and be properly secured to the bottom of the walkover and support posts. These clearances shall be maintained if the elevation of the beach rises or lowers after construction.

12. A preconstruction conference shall be held prior to the electrical rough-in for installation of exterior lights, and include the electrician or electrical contractor, the owner or authorized agent and staff representatives of the Department and the FWC.
