Community Rating System (CRS)

The National Flood Insurance Program (NFIP) Community Rating System (CRS) was implemented in 1990 as a voluntary program for recognizing and encouraging community floodplain management activities exceeding the minimum NFIP standards. Any community in full compliance with the minimum NFIP floodplain management requirements may apply to join the CRS

Nearly 3.6 million policyholders in 1,444 communities participate in the CRS by implementing local mitigation, floodplain management, and outreach activities that exceed the minimum NFIP requirements. Under the CRS, flood insurance premium rates are discounted to reward community actions that meet the three goals of the CRS, which are: (1) reduce flood damage to insurable property; (2) strengthen and support the insurance aspects of the NFIP; and (3) encourage a comprehensive approach to floodplain management. Although CRS communities represent only 5 percent of the over 22,000 communities participating in the NFIP, more than 69 percent of all flood insurance policies are written in CRS communities.

The City of Morgan City has been a proud CRS community since October 1991. Through this program our residents currently receive a 5-10% reduction on their flood insurance policies.

Our City is the only CRS Community in the Parish of St. Mary.

If you require help identifying the placement of your property concerning flood zones you may contact the Department of Planning and Zoning for personalized assistance or access the Online Map Search provided by FEMA. The FEMA site allows a citizen to do a flood zone search by property address. Another easy-to-use map that is is located at LA FloodMaps.


Elevation Certificates


The National Flood Insurance Program (NFIP) Elevation Certificate (EC) (FEMA form 086-0-33) is an administrative tool of the NFIP which is to be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or support a request for a Letter of Map Amendment (LOMA) or a Letter of Map Amendment based on fill (LOMR-F).

This document is referenced in the NFIP Flood Insurance Manual (Special Certifications Section). This form is fillable and can be completed in either Adobe Acrobat Pro or Adobe Reader and saved.

What You Need to Know About Floodplain Management


The City of Morgan City is dedicated to minimizing the loss of life and property that is associated with flooding events. Education and prevention are valuable and proven tools that help communities become resistant to these natural disasters. The City of Morgan City recognizes that its entire community is susceptible to flooding, not just those structures located within Special Flood Hazard Areas (SFHA’s). The following information has been provided to help inform property owners located within the SFHA, flood prone areas and also all property owners within the City of Morgan City.


The City of Morgan City is located in the eastern portion of St. Mary Parish approximately 20 miles from the Gulf of Mexico. The area consists mainly of low coastal marshes with ridges of higher alluvial land along the rivers and bayous. Morgan City is situated along the east bank of the Atchafalaya River at the intersection of the Gulf Intracoastal Waterway. Lake Palourde lies to the north and east of the city. The Atchafalaya River, the Gulf Intracostal Waterway and other watercourses in the area have made Morgan City attractive to the fishing, construction, transportation and petroleum industries. Although ponding of runoff produced by rainstorms and hurricanes causes significant flooding in Morgan City, the most severe flooding in the major part of the City has been caused from the Atchafalaya River, a tributary of the Mississippi River. Major floods of the Mississippi River and its tributaries occurred in 1927, 1937, 1945, 1950, 1973, 1974, and 1975. The flood of 1927 was the most disastrous in the recent recorded geological history of the lower Mississippi River Valley. A significant portion of land adjacent to the Atchafalaya River was inundated by the floodwaters of 1927. Flooding extended continuously from the Teche Ridge (west of Morgan City) to Lafourche Ridge (east of Morgan City). The flood of 1927 had an estimated recurrence interval of 50 years. The flood of 1973, which had an estimated recurrence interval of 40 years, was the largest flood on the Mississippi River since 1927. The maximum stage of the Atchafalaya River at Morgan City during the 1973 flood was 10.5 feet, or 2.5 feet below the top of the floodwall. During the 1973 flood, heavy losses were experienced by industries located on the Atchafalaya River side of the levee in Morgan City.


1. Learn the safest route from your home or business to higher, safer ground, but stay tuned to reports of changing flood conditions.

2. If emergency officials tell you to evacuate or leave your home, go immediately to a safe shelter, hotel or relative’s house.

3. Turn off all utilities, gas and electricity at the main switch. Stay away from power lines and electrical lines. Be alert for gas leaks.

4. Do not walk through flowing water. Drowning is the number one cause of flood related deaths. Currents can be deceptive; six inches of moving water can knock you off your feet.

5. Do not drive through a flooded area. More people drown in their cars than in any other location. Vehicles also push water into homes and cause additional property damage.


The purchase federal flood insurance is highly recommended. Basic homeowner’s insurance policies don’t cover damage from floods. The City of Morgan City participates in the National Flood Insurance Program (NFIP) which means that federally subsidized flood insurance is available to everyone in the City. Remember there is a 30-day waiting period before a policy becomes effective. Some people have purchased flood insurance because it was required by the bank or loan company when they obtained a mortgage or home improvement loan. Usually these policies just cover the building’s structure and not the contents. During the kind of flooding that happens in the City of Morgan City, there is usually more damage to furniture and the contents than there is to the structure. Remember that a flood insurance policy must be renewed each year. Mandatory Purchase Requirement: The mandatory purchase requirement applies to all forms of federal or federally related financial assistance for buildings located in a Special Flood Hazard Area (SFHA). This requirement affects loans and grants for the purchase, construction, repair, or improvement of any publicly or privately owned buildings in the SFHA, including machinery, equipment, fixtures and furnishings contained in such buildings. If a building is located in a SFHA, the agency or lender is required by law to require the recipient to purchase a flood insurance policy on the building.

For more information about flood insurance contact:
● The Morgan City Public Library.
● Contact your insurance agent.
● Contact the Morgan City Planning and Zoning Department.


Rather than wait for a flood to occur, you can act now to protect your property from flood damage. Various alternatives are available to help minimize flooding. If the floor level of your property or structure is lower than the Base Flood Elevation (BFE) located on the City’s Flood Insurance Rate Map (FIRM), consider ways to prevent flooding from occurring such as retrofitting your building. “Retrofitting” means altering your building to eliminate or reduce flood damage.

Retrofitting measures include:
● Elevating the building so that flood waters do not enter or reach any damageable portions of it,
● Constructing barriers out of fill or concrete between the building and flood waters,
● “Dry floodproofing” to make the building walls and floor watertight so water does not enter,
● “Wet floodproofing” to modify the structure and relocate the contents so that when flood waters enter the building there is little or no damage, and
● Preventing basement flooding from sewer backup or sump pump failure.

There are several good references on retrofitting in the Morgan City Public Library. Many of these will inform you about retrofitting techniques and help you decide which is best for you.


The City of Morgan City is a beautiful place to live. The undisturbed marshes and wetlands provide a wide range of benefits to the human and natural systems. They provide flood storage and conveyance, reduce flood velocities and flood peaks. Water quality is improved through the marshes and wetlands ability to filter nutrients and impurities from runoff and process organic wastes. The local marshes and wetlands provide breeding and feeding grounds for fish and wildlife, create and enhance waterfowl habitat, and protect habitats for rare and endangered species. The floodplains are an important asset. They provide open space, aesthetic pleasure, and areas for active and passive uses.

What is substantial improvement? The National Flood Insurance Program (NFIP) requires that any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure before the start of construction of the improvement, must conform or meet the same construction requirements as a new building and be constructed above the minimum Base Flood Elevation (BFE) listed on the City of Morgan City’s Flood Insurance Rate Map (FIRM). What is substantial damage? Substantial damage means damage of any origin sustained by a building or structure when the cost of restoring the building to its pre-damaged condition would equal or exceed 50% of the market value of the building before the damage occurred. Substantial damage is determined regardless of the actual repair work performed. The City of Morgan City requires by ordinance that any substantial improvement or substantial damage improvement must have a building permit. Permit information can be obtained at the Planning and Zoning Department located at City Hall or by calling at (985) 380-4724.
