[ARCHIVED] Public Notice Concerning FEMA Project

FINAL PUBLIC NOTICE

The City of Fort Madison, Iowa has applied for Federal Emergency Management Agency 

(FEMA) Public Assistance (PA) Program funding through Iowa’s Homeland Security and Emergency Management Division (IHSEMD) as a sub- recipient. 

Under the National Environmental Policy Act (NEPA), federal actions must be reviewed and evaluated for feasible alternatives and for social, economic, historic, environmental, legal, and safety considerations. Under Executive Order (EO) 11988 and EO 11990, FEMA is required to consider alternatives, and to provide a public notice of any proposed actions in or affecting floodplains or wetlands. EO 12898 also requires FEMA to provide the opportunity for public participation in the planning process and to consider potential impacts to minority and low-income populations. This notice may also fulfill requirements under Section 106 of the National Historic Preservation Act (NHPA). 

Funding for the proposed project will be conditional upon compliance with all applicable federal, tribal, state, and local laws, regulations, floodplain standards, permit requirements and conditions. 

Sub-Applicant: City of Fort Madison 

Project Title: 109615-Marina Rip Rap, PA-07-IA-4421-PW-00341 

Location of Proposed Work: 

    At the Fort Madison Marina and Riverview Park along the Mississippi River from approximately 40.62873, -91.299679 to 40.628423, -91.304801.

    Work area is downstream of the Fort Madison Bridge.

Special Flood Hazard Area Zone:  

This project will perform work in the AE Zone, the area of 1% annual chance of flooding, and in the floodway per Lee County FIRM panel 19111C0218D, dated 7.22.2020. 

Proposed Work and Purpose: 

The City of Fort Madison will construct an improved project at the marina (40.628676, -91.302645), consisting of a new jetty wall that will be realigned and raised to the 500-year elevation, which will help control the sediment that enters the marina due to overtopping at its pre-disaster elevation(s). The core trench of the new jetty will be constructed of pit run rock to just above water level. Compacted earthen embankment and pit run rock will also be utilized above water level. The relocated jetty will be approximately 15 ft wide on top with a 2ft /1ft slope using rip rap for the slope and toe of the jetty. The improved project will not change the use of the land. The improved jetty will be lengthened modestly and built to a higher elevation (level of the 500yr storm). Sediments deposited in the marina during over-topping events will be dredged and the existing jetty removed. The dredged sediments and existing materials will all be placed in Riverview Park to help raise the park area above the 100-year flood elevation. 

Project Alternatives: 

Alternative #1 (No Action): The no-action alternative would not be appropriate because it would leave the Fort Madison Marina jetty wall subject to future overtopping and the marina subject to future flooding and accumulation of sediment rendering it potentially unusable in the future in the event of flooding.  

Alternative #2 (Repair In-Kind): Work could restore the existing jetty wall to current location and elevation by replacing 1,666.6667 CY of rip rap 750 FT long x 40 FT wide x 1.5 FT deep. This option would not be appropriate as it would leave the Fort Madison Marina and Riverview Park susceptible to future flooding.  

Alternative #3 (Jetty wall realignment and elevation): This is the option being pursued by this grant. Work will construct a new jetty wall that will be realigned and raised to the 500-year elevation, which will help control the sediment that enters the marina due to overtopping at its pre-disaster elevation(s) and will protect the marina and Riverview Park from flooding during future events.  

Comment Period: 

This will serve as the final public notice regarding the above‐described action funded by the FEMA PA program. All comments received can be submitted online, via email, to FEMA at teri.toye@fema.dhs.gov. Please use the subject line: “IA-4421-PW-341, City of Fort Madison Marina Rip Rap”. 

Interested persons may also submit comments and questions in writing, or request a map of this specific project, by writing to the Federal Emergency Management Agency, Region 7, 11224 Holmes Road; Kansas City, MO 64131. Written comments should be sent with the subject line “IA-4421-PW-341, City of Fort Madison Marina Rip Rap”, to the above address within 15 days of the date of posting.
