The neighborhood is approximately 15.5 acres in size and consists of two roadways, Ocean Inlet Drive and Shore Drive, and 64 single- family residences. The project will be implemented in the City's right-of-way and easements granted to the City for outfalls. See Exhibit A-Project Location Map.

R1817, R1906,and 22RRE09).The CVA identified the most vulnerable areas in Boynton Beach as areas with aging infrastructure and where critical facilities are located near waterbodies; particularly areas with relatively low elevation. Coquina Cove is one of these areas, bordered by the Intracoastal Waterway and the Boynton Canal, with elevations ranging from 8-9 ft. (NAVD 88)at the west entrance of the neighborhood down to approximately 4 ft.where the roads end at the Intracoastal Waterway. Specifically, the CVA found that both roads in Coquina Cove, the majority of single-family residences, and critical stormwater, wastewater, and drinking water infrastructure are highly vulnerable and at risk to current storm surge and rainfall- induced flooding, both of which worsen in future sea level rise scenarios for 2040 and 2070.Although tidal flooding is not a current problem in the neighborhood,the CVA found 20%of the neighborhood's parcels and all of Shore Dr.to be vulnerable to this threat in 2070. Currently the neighborhood experiences road flooding from heavy rainfall events and storm surge.This drainage improvement project is needed to improve level of service to the neighborhood by protecting all structures from flooding in the 100-year/72-hour design storm event, and keeping roadways to 0.5 feet or less of flooding for the 10-year/72-hour event and 0.8 feet or less for the 25-year/72-hour event. The need for drainage improvements was identified in 2019 when the City's Public Works department evaluated the Coquina Cove neighborhood for a planned road resurfacing project.This resulted in coordination between PW and Utilities and broadening the scope to include rehabilitation of drainage, sanitary sewer,and drinking water infrastructure.The assessment found that the neighborhood lacked stormwater inlets resulting in insufficient drainage to the Intracoastal Waterway,and that existing drainage structures were undersized and in need of an upgrade. It also identified the needs to replace aging and undersized water mains, replace sanitary sewer laterals to the homes, add https://fdep.my.salesforce.com/a195G00000X3kuEQAR/p 2/9 9/6/22, 10:48 AM RAN-00474-Salesforce-Enterprise Edition lining to the sanitary sewer main to resolve leakage and inflation as wells as to extend its useful life,and address continually failing asphalt on top of the sanitary sewer pipe segment.The report concluded that the City should develop a complete utilities improvements project. Project Fit The Coquina Cove Drainage Improvements project entails necessary modifications and supplementations to Stormwater Infrastructure to improve drainage level of service.The project addresses Coastal Flood Control and aims to Mitigate Threats from Flooding and Sea Level Rise identified in the comprehensive vulnerability assessment. The project also addresses Transportation and Evacuation because it involves flood mitigation on two neighborhood roads which need to be safe to drive for residents to egress the community and access the evacuation route on N. Federal Hwy. The project includes replacement and upgrades to Domestic Wastewater Infrastructure and Utilities Infrastructure including the sanitary sewer system and replacement of a drinking water main. GI Critical Asset VAAP Yes GI Critical Asset VAAP The CVA assessed vulnerabilities and Explanation risks to tidal flooding, storm surge, and rainfall-induced flooding for current (2020)conditions, NOAA intermediate- low projection for 2040(4"above 2020), NOAA intermediate-high 2040/intermediate-low 2070(11"), and NOAA intermediate-high 2070 (33"). The assessment identified both roads (Shore Dr. and Ocean Inlet Dr.)and 82%of the 64 residential parcels in Coquina Cove neighborhood as highly vulnerable and at risk to 2020 and 2040 storm surge and 2020 rainfall flooding; and 98%of residences as highly vulnerable and at risk to 2070 storm surge and 2070 rainfall flooding. Tidal flooding was not found to be an immediate threat, but by 2070 80%of parcels were in inundation extent with 20% identified as medium to high vulnerability.The project will reduce these risks by upgrading the Coquina Cove drainage system (including piping, drainage structures, outfalls, grading and paving)to increase flood resilience. GI Flood Erosion Yes GI Flood Erosion The rainfall-induced flooding threat in the Reducing Reducing Explanation CVA is technically a measure of compound flooding (as defined in 62S- 8.002).The model combined rainfall depth over the 100-year, 24-hour storm event with sea level rise estimates (added to the existing conditions high- tide value)to estimate future water depths.The assessment identified the roads (Shore Dr. and Ocean Inlet Dr.) and 97% of the 64 residential parcels in Coquina Cove neighborhood as highly vulnerable and at risk to 2020 rainfall flooding;and 98%of residences as https://fdep.my.salesforce.com/a195G00000X3kuEOAR/p 3/9 9/6/22, 10:48 AM RAN-00474-Salesforce-Enterprise Edition highly vulnerable and at risk to 2070 storm surge and 2070 rainfall flooding. In an additional analysis for confidential water infrastructure,the CVA found the entirety of Coquina Cove would be inundated by the 100-year, 24-hour rainfall combined with 2020 storm surge. The project will reduce these risks by upgrading the Coquina Cove drainage system(including piping, drainage structures, outfalls, grading and paving) to increase flood resilience. GI Regionally No GI Regionally Significant Significant Explanation GI Percent CA 80%or more GI Percent CA "Medium to high vulnerability and risk" Vulnerable Vulnerable (V&R)was defined based on exposure, Explanation sensitivity,adaptive capacity, risk probability and risk consequence. Storm surge and tidal flooding were assessed for 2020, 2040, and 2070 sea-level rise scenarios outlined in paragraph 380.093(3)(d), F.S. Rainfall-induced flooding was assessed for 2020(100-yr and 500-yr), 2040 (100-yr, 5"SLR above 2020 baseline)and 2070 (100-yr, 33" SLR). Critical assets identified as V&R for rainfall-induced flooding and storm surge (2020, 2040, and 2070)include: Critical stormwater infrastructure: 100%- all 4 stormwater outfalls Drinking water distribution system: 100% -AC water main on Ocean Inlet Dr. Wastewater conveyance system: 97% - sanitary mains and sanitary laterals Transportation: 100%-Shore Dr. and Ocean Inlet Dr. potentially isolated; 2070 also includes portions of N. Federal Hwy.

Problems also arise with ground saturation from continuous rainfall events. Documentation is presented in attached Exhibit D-Alternatives Analysis Report (results pp. 5-6 and map p.8).Tables 2, 3 and 4 document that the existing drainage system fails to meet level of service in 5 of the 7 modeled subbasins for the 10-year/72-hour and 25-year/72- hour storm events; and in 4 subbasins for the 100-year/72-hour event.This https://fdep.my.salesforce.com/a195G00000X3kuEQAR/p 4/9 9/6/22, 10:48 AM RAN-00474-Salesforce-Enterprise Edition means that in these areas, roadways are currently not protected from 0.5 feet of flooding for the 10-year event and 0.8 feet for the 25-year event; and structures are not protected from flooding in the 100-year event.

Coquina to existing outfalls, upgrading a 4-inch Cove is a low-lying coastal area with outfall to 24-inch, complete standard aging infrastructure that currently paving and grading, replacement of an experiences road flooding from heavy existing Asbestos-Cement(AC)water rainfall events and storm surge.The City main, lining of sanitary mains, conducted site reconnaissance and replacement of sanitary laterals,and determined that the neighborhood has utility relocation to accommodate the an insufficient drainage network that drainage improvements. needs modifications or supplementations.The current system utilizes four(4)existing outfalls ranging https://fdep.my.salesforce.com/a195G00000X3kuEQAR/p 6/9 9/6/22, 10:48 AM RAN-00474—Salesforce-Enterprise Edition in diameter between 4 inches and 24 inches. Drainage is directed to inlets adjacent to the outfalls, leaving vast areas underserved.The Coquina Cove Drainage Improvements project is designed to address existing drainage issues and result in an improved level of service to the neighborhood. The City's coordination between Public Works and Utilities began in 2019 to define the neighborhood needs and project scope. In 2020 the City contracted a comprehensive survey for the entire neighborhood, including topography,elevations, utilities, easements, edge of pavement,and landscaping. In May 2021, the City Contracted with AECOM for the design, permitting, public engagement and limited services during construction. AECOM provided 60%construction plans and a preliminary cost estimate in July 2022. Public meetings were held in July 2021 and August 2022. The project scope includes adding catch basins to connect to the 3 existing outfalls,grading,and replacement of the outfall at the east end of Shore Drive (currently 4")with a 24-inch pipe (see Exhibit B-Outfall Map). Currently,the City is working to attain a drainage easement to enable installation of that outfall.Additional project components address necessary improvements to aging infrastructure in the drinking water and sanitary sewer systems, including replacement of the existing AC water main on Ocean Inlet Drive, addition of fire protection, manhole rehabilitation, cured in-place pipe lining, sanitary laterals replacement, and associated utility relocation to accommodate the proposed drainage system.

Coquina Cove - Exhibit C-pg. 2 AECOM Imagine it. AECOM Delivered. 2090 Palm Beach Lakes Blvd,Suite 600 West Palm Beach,FL 33409 aecom.com Project name: City of Boynton Beach—Coquina Cove Drainage Improvement Project Project ref: To: 60654448 Ms.Angela Prymas, PE From: City of Boynton Beach Amy Eason,PE 124 E.Woolbright Road Boynton Beach, FL 33435 Date: June 22,2021 CC: Technical Memo Subject: Alternatives Analysis Evaluation Report Introduction The City of Boynton Beach has identified the Coquina Cove neighborhood as having an insufficient drainage network that needs modifications or supplementations. The current system utilizes four (4) existing outfalls ranging in diameter between 4-inches to 24-inches. Drainage is directed to inlets adjacent to the outfalls, leaving vast areas under served. To provide the best solution, AECOM conducted a 1D hydrologic analysis of the project area along with three (3)alternatives.Alternative 1 utilized the existing outfalls and provided an interconnected drainage network to better convey stormwater to the existing outfalls.Alternative 2 added more outfalls while still utilizing an interconnected drainage network. Alternative 3 utilized the existing outfalls with the addition of interconnecting the system with exfiltration trenches. Methodology To conduct the analysis, a range of software was utilized such as AutoCAD, ArcGIS, and ICPR 4. A highlight of key model building blocks has been compiled and is described below: Subbasins Subbasins were developed utilizing the City-provided AutoCAD survey to identify high spots and locations that are underserved. Subbasins were created with alternatives and the proposed layouts in mind. This was to reduce the need to recut subbasins and allow for one set to be used to have an "apples to apples" comparison when analyzing the results. In addition, the subbasin boundaries were adjusted to be on top of the seawalls. Appendix A shows the location of each subbasin and Table 1 summarizes the area of each subbasin. DRAFT 1/7 Technical Memo DRAFT City of Boynton Beach—Coquina Cove Drainage Improvement Project Table 1 Subbasin Areas Name Area (acres) CC_1 2.27 CC_2 2.44 CC_3 2.06 CC_4 2.29 CC_5 1.62 CC_6 2.20 CC_7 2.94 It was assumed that the curve number for each subbasin would be 95 based oon the lots being highly developed with minimal pervious areas. Stage Area Lidar information was utilized to generate stage area data within ICPR 4. The Lidar was processed using the Palm Beach County 2017 Lidar point cloud data set with vertical accuracy of ±0.59 feet. The data set was modified to correct for low point density along the water's edge. A hard boundary was set to represent the sea wall at 4 feet NAVD. A bare earth float raster was created that represents the terrain without vegetation or structures. In a spot test with the City-provided survey in non-vegetated terrain, the average accuracy was ±0.16 feet. Boundary Stage Data from NOAAs tidal monitoring stations were used to best represent the tailwater conditions. The closest monitoring station to the project site was located at the Lake Worth Beach Pier approximately 5 miles away. The sea level used in the model to represent the tailwater was the Mean High Water (MHW) elevation, which had a reported value of 0.37 feet NAVD88. Figure 1 shows the monitoring station's recorded values.

The City-provided AutoCAD Survey was utilized to create the overland weirs and set the outfall inverts. The overland flow weirs only considered the 50 foot road right-of-way. It was assumed the residents are responsible to convey all runoff to the front of their lots and into the City's right-of-way for discharge. It was assumed the outfalls did not have any backflow prevention devices. Swales Swales were not considered within the modeling to be more conservative and to best illustrate the effects of each solution. Geotechnical/Groundwater At the time of writing this report the geotechnical subconsultant (Terracon) had not completed their analysis of the project site. Therefore, some assumptions where made to expedite the modeling analysis. The groundwater was estimated based off the Mean Higher High Water (MHHW) elevation of 1 0.55 feet NAVD88 (found in Figure 1) with 1 foot added to represent the freshwater lens. The result is an estimated groundwater elevation of 1.55 feet NAVD88. Storm Events AECOM has modeled the 10-year 3-day, 25-year 3-day, and 100-year 3-day storm events. Each simulation utilized the SFWMD 72 hour rainfall distribution curve. Rainfall amounts are derived from SFWMD ERP Handbook Volume II rainfall isohyetal maps. The rainfall amounts are 11.5 inches for the 10-year 3-day, 14.5 inches for the 25-year 3-day, and 18 inches for the 100-year 3-day. AECOM DRAFT 3/7 Technical Memo DRAFT City of Boynton Beach—Coquina Cove Drainage Improvement Project Warning Stages The level of service/warning stage has been set so that the 10-year 3-day storm is allowed 0.5 feet of water above the minimum crown of road, the 25-year 3-day storm is allowed 0.8 feet of water above the minimum crown of road, and the 100-year 3-day storm is set to the lowest finished floor elevation per subbasin. Modeling Alternatives Alternative 1 —Alt 1 consists of interconnecting the existing outfalls.A 24-inch diameter RCP pipe was found to be most suitable as it did not exceed the existing discharge capacity and provided the ability to avoid nearby existing infrastructure. It is recommended in this alternative to replace the existing catch basins and structure to maximize the effectiveness of each outfall. The conceptual layout can be found in Appendix B. Alternative 2 —Alt 2 provided a similar interconnected system as Alt 1 with a 24-inch diameter RCP pipe, but also added three (3) additional outfalls. Each new outfall was sized to best meet the discharge requirements of the study area. From the analysis, all three (3) proposed outfalls are sized to be 24- inches. The minimum easement size the City will need to secure to fit the proposed outfalls is 10 feet. The conceptual layout can be found in Appendix C. Based on the meeting held May 27th, 2021 with the City, that water quality should not be an issue with the permitting agencies. An amendment to this report may be needed after the pre-application meeting with the permitting agencies. Alternative 3 — Alt 3 interconnected the existing outfalls utilizing 24-inch diameter RCP pipe with sections of exfiltration trench. The dimensions of the exfiltration trench are 6 feet wide by 6 feet tall, with a 24-inch diameter perforated pipe. In order to satisfy the City's requirement to reduce impacts to residential landscaping, the exfiltration trench was designed to be within the roadway and utilize the City's standard detail for exfiltration trenches. The proximity of the groundwater in relation to the surface will impact the effectiveness of the proposed exfiltration trench by reducing the available unsaturated layer. The reduction in the unsaturated layer will leave parts of the trench fully saturated, further reducing the cost effectiveness. Alternative 3 built out the maximum length of exfiltration trench available to compensate for the reduced unsaturated layer. The conceptual layout can be found in Appendix D. AECOM DRAFT 4/7 Technical Memo DRAFT City of Boynton Beach-Coquina Cove Drainage Improvement Project Analysis Tables 2, 3, and 4 summarize the model results for the 10, 25, and 100-year storm events. The results in red represent stage elevations above the set warning stage, indicating a failure to meet level of service. Alternative 2 is the only proposed solution that did not fail to meet the level of service.

The analysis illustrated that only Alternative 2 was able to produce results that did not exceed the minimum crown for some of the storm events.Alternative 2 was able to stay below the minimum crown of road for the 10-year and 25-year storm events. Cost AECOM has performed an engineering preliminary cost analysis for each alternative. Table 5 summaries the total cost. Appendix E has the total cost breakdown. Please note that the cost estimates do not include sanitary sewer or potable water work. Table 5 Summary of Preliminary Cost Estimates Alternative Cost Alt 1 $953,700 Alt 2 $3,240,700 Alt 3 $2,153,200 The preliminary cost estimates indicate that the cheapest option would be to implement Alternative 1, however, when weighed with the results, the improvements do not meet the City's level of service. Alternative 2 is the most expensive solution and the only solution that meets the level of service set forth by the City. AECOM DRAFT 6/7 Technical Memo DRAFT City of Boynton Beach—Coquina Cove Drainage Improvement Project Recommendations Based on the model results and cost estimates Alternative 2 provides the best cost benefit to improve drainage within the Coquina Cove neighborhood. Alternative 2 is the only model that consistently provides improvement for each simulated storm event and has the greatest impact. It is recommended that the City look to implement the Alternative 2 design approach and look to add swales where applicable to provide additional storage and water quality.
