Northeast Corridor Greenway Acquisition – Mitigation Feasibility Study ResultsCity Council WorkshopJune 24, 2014
Strategic Action Plan
Presentation Outline
Background:• Northeast Corridor Projects Action Plan
• Project Location• Project Benefits• Consultant Selection
Feasibility Study Results:• Feasibility Study
• Project Objective and Scope• Findings
Recommendation:
Northeast Corridor
Acquisition Benefits
Potential Benefits of Land Purchase• Wetland Mitigation – Potential to create mitigation credits for use of transportation
and other city projects in lieu of purchasing mitigation credits from a wetland mitigation bank.
• Recreational Uses - Investigate passive recreational uses of the site to expand connectivity to other lands to expand public uses.
Primary Benefits of Land Purchases• Cost Savings & Timing – Ability to avoid eminent domain proceedings. Ability to keep
projects moving forward with the Interchange project schedule. • Floodplain Compensation – Land necessary for completion of Northeast Corridor
projects.• City control of Special Flood Hazard Area (SFHA) - Critical component in the National
Flood Insurance Program (NFIP) and the City’s community rating that directly affects flood insurance rates.
• Water Quality - Benefits water quality in the Pellicer Creek Basin.• Habitat - Expands the existing regional conservation corridor and ecological
significance due to the unique linkage to conservation areas to the north and south.
NE Corridor Greenway Acquisition(NECGA) Mitigation Project
Project Site
November 19, 2013: Resolution issued to execute a Work Order to Jones Edmunds & Associates, Inc.
• Project Objective – Produce a feasibility study to guide the City on project costs and timing of design, permitting, monitoring and overall management of the NECGA with a cost-benefit analysis in-mind.
• Total Project Budget 2013-2014: $150,000.00
• Cost of Services for Study - $35,278.00 $114,722.00

Recreation / Floodplain Storage
Rec. Improvements : $215,500 - $659,000Floodplain Storage: $32,000 - $60,000
Findings Focus:• Feasibility Study identified Alternatives (Options)
• Integrates input from St. Johns River Water Management District and U.S. Army Corps of Engineers
• A cost / benefit analysis was conducted for each of the following
1: Required restoration only:1A: SJRWMD – approved restoration plan1B: Compensation Plan
2: Optional Wetland Mitigation Program: 2A: Restoration & Enhancements -> 5 credits2B: Restoration & Enhancements - > 10 credits
**Note: Floodplain & recreational elements cost(s) identified separately
NECGA – Mitigation Feasibility Study
Analysis included cost estimates for the following:
• Permitting (if applicable), Design & Engineering• Mobilization (includes surveying and “record drawings”)• Erosion and Sediment Control (materials and labor)• Clearing and grubbing• Earthwork (excavation, embankment, grading etc.)• Plant material, installation, supplemental planting (if needed)• Maintenance of exotic/invasives – Min. 5 Years• Compliance Monitoring and Reporting – Min. 5 Years• 10% Contingency

(8.0 acres)
Staff Summary of Findings
Regulatory Required Restoration: • Requires detailed engineering and design• 1A (Approved = $1,950,000) vs. 1B (Compensation = $1,420,000)• Approximately 50% of cost is clearing and ground work• Approximately 50% of cost is distributed over a minimum 5-year period• 1A is more costly overall and difficult to construct – no permitting required• 1B is preferred option to prepare and permit future options for recreation and wetland
mitigation credit • 1B creates consolidated potential public viewing area and greatly likelihood of success
Findings Focus:• Feasibility Study identified 3 primary Alternatives (Options) for action.
• Integrates input from St. Johns River Water Management District and U.S. Army Corps of Engineers
• A cost / benefit analysis was conducted for each of the following.

Staff Summary of Findings
Wetland Mitigation Feasibility Options• Requires detailed engineering, design and permitting • Agency permitting will establish final credit count vs. cost• With exception of potential recreational improvements, property perpetually
preserved• Ecological enhancements will be of significant value for future attractions• Perpetual minimal land management obligation
