Slide 1: Overview

What…

🌧️ After Debby, the Warning Was Clear

Tropical Storm Debby – October 2024
Multiple homes surrounded by floodwater.
Garages and lanais soaked.
Intersections under water.
The potential cost? High. The risk? Rising.


🚨 Rising Threat of Stormwater Damage
  • Property at risk
  • Costly repairs
  • Liability exposure growing

🛠️ We Acted Fast

Weber Engineering — the original drainage designer —

  • Re-engaged to reassess the system
  • Identified key deficiencies
  • Tailored solutions for long-term protection

✅ What This Means for Us
  • Proactive protection
  • Smarter stormwater management
  • Lower risk, lower costs

💡 Protect Property. Prevent Flooding. Plan Ahead.

Our Task Force is on it — for your safety, your home, and your peace of mind.

Why…

🌩️ When the Storms Get Stronger, So Must Our Systems

As severe weather events become more prevalent, it is imperative for HOA’s and COA’s to identify insufficiencies and hazards in their storm drain systems.


🛡️ Flood-Proofing is Not Optional—It’s Necessary

Flood-proofing measures are no longer simply prudent—they are essential to protect homeowners, preserve property values, and safeguard the association’s financial stability.

How…

📊 Detailed Stormwater Survey by Weber Engineering

Weber Engineering surveyed the areas on our property most prone to stormwater pooling, measuring elevations and analyzing land contours in relation to our existing storm drain system.

Their findings are summarized in the report they submitted, which includes specific recommendations to help us mitigate the risk of flooding.

Slide 2: Executive Summary

🎯 Project Purpose

Provide the reasoning and data that demonstrate the necessity to implement these upgrades. This project is not merely an expense — it’s an investment in our safety and protection from catastrophic damage and liability.


🛡️ Primary Objective
  • Mitigate the risk of flooding and its impact on property values
  • Reduce legal and financial liabilities for the COA
  • Serve as a Master Plan — from contractor selection through full implementation

💡 Key Takeaways
  • Extensive due diligence supports our recommended solutions
  • Proactive investment now prevents costly consequences later
  • This project can be funded without a special assessment

Slide 3: Project Objectives

🌊 Core Objectives: Mitigation Through Smarter Stormwater Management
  • Mitigate flooding risks by efficiently managing and redirecting excess stormwater
  • Address deficiencies in the current drainage system, particularly where upward-sloping terrain has trapped water
  • Ensure a reliable outflow route for stormwater to prevent accumulation during excessive rainfall events

Slide 4: Failure to fix deficiencies – Risks

⚠️ Risks of Inaction
  • Foundation and structural damage can lead to costly repairs and unsafe living conditions
  • Liability may include legal costs, remediation orders, and financial consequences if inaction results in harm
  • Marketability suffers — both from actual flooding and the required disclosure of known drainage deficiencies to future buyers*

Slide 5: Current System Deficiencies

🌐 Lake Cormorant: A Site-Specific Vulnerability
  • Our property features a natural gradient — sloping from higher ground in the northeast to lower areas in the southeast
  • Lake Cormorant sits in the lowest-lying area and is especially vulnerable to breaching due to local runoff and storm impact
  • In tropical storms, excess rain triggers a cascade of events that causes Cormorant to overflow — spilling into Wilshire Circle East
  • Condos along the East Wall are built on elevated slabs, preventing natural water escape from the lake basin
  • This creates a bowl-like effect, flooding front and backyards, lanais, patios, and garages
  • The flooding starts at WCE/WD and WCE/WC (lowest elevations) and expands outward — affecting many units in the southeast quadrant
  • With stormwater having nowhere to go but up, structural flooding becomes inevitable with excessive rain events

Slide 6: Flood Risk Scenarios

Severe storms/Hurricanes/Heavy Rains

🌊 Backflow from the Gulf: A Chain Reaction
  • Storm surges in the Gulf can block northern outflow — in extreme cases, they reverse the stormwater flow
  • This pushes water backward into Philippi Creek, Mirror Lake, and eventually our retention ponds
  • The lowest-lying pond in the southeast quadrant fills rapidly, breaches, and spills into backyards and patios
  • As overflow worsens, curbside stormdrains along Wilshire Circle East reverse flow, causing Lake water to pool in the street

Slide 7: Flooding Hotspots

Visuals

During Tropical Storm Debby in October 2024, stormwater flooded front and backyards, garages, and low-lying patios of condos near Cormorant Lake along Wilshire Circle — coming within inches of entering living areas.

Slide 8: Proposed Engineering Solution

Installing Pipes to existing drains

🛠️ Proposed Drainage Solution: Use What Works, Connect What Doesn’t

Our solution utilizes existing collection basins (CBs) in the two lowest-lying areas and connects them via hard piping to existing storm drains along the east wall (berm).

  • Northern Connection: From WDR/WCE intersection to the drain near the east wall, running between Villa #90 and #158
  • Southern Connection: From the WCE-to-WC transition to the southern drain near the wall, running between Villa #163 and #164

Both drains along the berm follow the natural stormwater path into Matheny Creek.

The northern connection uses an 8″ pipe, the southern a 12″ pipe — both tie into a 48″ RCP that connects our system to the Matheny Creek watershed.

These connections follow natural land contours to facilitate efficient drainage away from our property.

See the Weber Report for the specific recommendations (The final report is pending)

Slide 9: Project Benefits Summarized

Slide 10: Financials

💰 No Special Assessment Required

This infrastructure improvement can be fully financed using existing Reserve Funds — no special assessment will be necessary.

This approach is consistent with standard practice for funding capital improvements that protect property and reduce long-term liabilities.

Slide 11: Implementation Timeline

Slide 12: Next Steps

📋 Next Steps: Action Plan
  • Receive the final report from Weber Engineering
  • Send out RFPs (Requests for Proposals) and SOWs (Statements of Work) to selected contractors
    (per Weber’s recommendations and Sandy’s vetted list)
  • Taskforce meets to review contractor bids, costs, and implementation options
  • Create a visual summary (table or chart) comparing proposed solutions
  • Present final recommendation to the Board and put to vote if needed
  • Maintain regular updates to the Board and community throughout the process

Slide 13: Conclusion

✅ A Smart Investment in Protection

This project safeguards residents, preserves property values, and strengthens the association’s financial health.

We respectfully count on the Board’s approval of the proposed plan — and the authorization of funding as outlined .
