- 9. Project Description/Overview
- The City of Diamondhead is seeking GOMESA funding from the Mississippi Department of Marine Resources for the Diamondhead Drainage, Flood Prevention & Water Quality Improvement Project Phase II. Phase I of the project was funded during the 2022 cycle and the proposed projects identified in Phase II include one of the subprojects that were not funded in Phase I due to budgetary constraints. Additionally, two subprojects have been identified as critical components to Diamondhead's drainage and water quality program specific to Watershed A (the largest watershed in the City of Diamondhead). The project consists of three subprojects that will provide drainage infrastructure improvements, wetland restoration and improve detention facilities to reduce flooding, improve water quality and preserve downstream wetland and estuarine habitats. The subprojects that are associated will improve water flow characteristics, reduce the future possibility of flooding of roadways and homes in the area, improve water quality downstream and extend runoff times. As part of a county-wide effort, Waggoner Engineering produced the Hancock County Watershed-Based Stormwater Assessment and Management Plan in December 2019 that included a step-by-step plan for implementation. The plan created by Waggoner Engineering provided Hancock County a storm management plan for the long-term future of the County that was realistic and manageable. The county-wide effort by Waggoner Engineering resulted in a detailed project description for the three subprojects of the Diamondhead Drainage, Flood Prevention & Water Quality Improvement Project. The following pages contain the full project descriptions from the Waggoner Engineering produced plan for Kome Drive, Anahalo and Fairway Drive.
- 10. Project Goals/Objectives
- • Kome Drive: Goals and objectives of this subproject are to improve flow characteristics, reduce possibility of flooding of roadway and homes in the area. The objectives include re-establishing ditch sections, ditch armoring to prevent erosion and replacing inadequate infrastructure with properly sized channels and culverts. The project will also investigate detention possibilities and establishing riparian buffers along streams in the Watershed. • Anahalo: Goals and objectives of this subproject are to improve flow characteristics, reduce possibility of flooding of roadways and homes in the area, improved water quality downstream and extended runoff times. As documented by Waggoner Engineering, the reported problems are water over the road in a typical storm event and houses flooding in the area multiple times. Site is the singular out fall for watershed with no detention facility. Previous methods for the handling storm water are causing expedited runoff times. Open ditches have been eliminated in places where they are needed. The recommended solutions for this subproject are to: re-establish open ditch sections where water is being forced onto the roadways; incorporate LID drainage measures in the channel (step pool) that increase runoff times to mitigate immediate problems and aid in addressing those downstream; build inline and offline detention within the watershed. • Fairway Drive: Goals and objects of this subproject are to improve flow characteristics, reduce possibility of flooding of roadways and homes in the area, extend future runoff times and improve water quality downstream. When documenting the reported problems with this subproject, Waggoner Engineering stated, "Ditch sections along Fairway drive and thru the easement are not large enough to accommodate the current volumes and there is potential for further development within the basins." The recommended solutions to remediate the problems associated with this subproject are to: Construct additional detention facilities, enlarge hydrologic section along Fairway Drive, remove, replace, install additional drainage structures under the roadway.
- 11. Which of the following authorized uses set forth in the GOMESA Act does this project fall under?
- (A) Projects and activities for the purpose of coastal protection, including conservation, coastal restoration, hurricane protection, and infrastructure directly affected by coastal wetlands losses
- Yes: The proposed drainage improvements identified in this project will have a direct positive impact on coastal wetland losses by reducing stream bank and wetland erosion along the major drainageways within Diamondhead. Additionally, the reduction in sedimentation will improve water quality in receiving streams and estuaries.
- (B) Mitigation of damage to fish, wildlife, or natural resources.
- Yes: The City of Diamondhead drains into Rotton Bayou, the Jordan river and tributaries to St. Louis Bay. These drainage projects will reduce erosion and improve water quality downstream which directly impacts natural resources in our bays and estuaries.
- (C) Implementation of a federally-approved marine, coastal, or conservation management plan.
- Yes: The proposed project is implementing recommendations made from the Hancock County Watershed-based Stormwater Assessment and Management Plan, a comprehensive conservation management plan for Hancock County.
- (D) Mitigation of the impact of Outer Continental Shelf activities through funding of onshore infrastructure projects.
- Yes: The City of Diamondhead drains into Rotton Bayou, the Jordan river and tributaries to St. Louis Bay. These drainage projects will reduce erosion and improve water quality downstream which directly impacts natural resources in our bays and estuaries.
- 12. Project Timetable/Milestones
- -Kome Drive Implementation Period: 1.5 Years Study: Completed Design and Permitting: Six Months Construction: One Year Estimated Schedule: July 1, 2023 - December 30, 2024 -Anahalo Implementation Period: 2 Years Study: Six Months Design and Permitting: Six Months Construction: One Year Estimated Schedule: July 1, 2023 - June 30, 2025 -Fairway Drive Implementation Period: 1.5 Years Study: Complete Design: Six Months Construction: One Year Estimated Schedule: July 1, 2023 - December 30, 2024

- Other H&H modeling underway Funds Not Budgeted
- 15. In what way does this project meet the goals and objectives of the Department of Marine Resources, which includes enhancing, protecting and conserving the marine interest of Mississippi for present and future generations?
- Diamondhead Drainage, Flood Prevention & Water Quality Improvement Project Phase II in Hancock County is primarily a drainage infrastructure improvement project that meets the following Mississippi Department of Marine Resources criteria: activities for the purposes of coastal protection, including conservation, coastal restoration, hurricane protection and infrastructure directly affected by coastal wetland losses; and implementation of a federally approved marine, coastal or comprehensive conservation management plan. The Diamondhead Drainage, Flood Prevention & Water Quality Improvement Project will provide significant drainage infrastructure improvements that will provide future hurricane protection and infrastructure directly affected by coastal wetland losses. The project consists of three subprojects that will provide drainage infrastructure improvements, wetland restoration and improve detention facilities for future watershed events. The proposed project is also implementing recommendations made from the Hancock County Watershed-Based Stormwater Assessment and Management Plan, a comprehensive conservation management plan for Hancock County.
