ELEVATION SCOPE OF WORK

1.0 CONTRACTORS ARE REQUIRED TO:

1.1 Use a hydraulic lift system when elevating the home.

1.2 Provide professional labor, equipment, and materials adequate to perform the work in accordance with the scope of work for each eligible applicant's residential structure while ensuring that all applicable housing standards and codes are met;

1.3 Ensure all elevation work will be performed to meet or exceed all local, state and federal building codes and standards;

1.4 Ensure all elevation work will bring the structure into compliance with the National Flood Insurance Program by requiring elevations to be two feet (2’) or more above the Base Flood Elevation as identified in the Preliminary Flood Insurance Map (FIRM).

In rare cases, the adopted FIRM may be more stringent than the Preliminary FIRM— in these unlikely instances; the adopted FIRM data will be used.

Elevation certificates shall be required before the elevation commences, and upon completion to verify the elevation and achieve compliance with local floodplain requirements.

1.5 If the homeowner selects your company, you will meet with the individual property owners to review the scope of work to be performed, including establishing a work schedule acceptable to property owners and the County’s Program Manager; Prepare plans and specification and perform elevation in compliance with applicable City or County floodplain elevation requirements, code requirements, and Texas Windstorm Insurance Association (TWIA) requirements; Provide initial first floor elevation and obtain final elevation certificate.

1.6 All damages caused by the contractor during the elevation project shall be paid for by the contractor; these damages are ineligible grant costs and the FEMA program does not cover such costs. These are the responsibility of the contractor.

1.7 Obtain all necessary state and local permits and approvals after permits are acquired. Prior to the commencement of the work for each home, copies of all permits not issued by the County shall be provided to the County;

2.0 BACKGROUND INFORMATION

A residential elevation is when a house that is vulnerable to flooding is physically raised to an elevation at or above the Base Flood Elevation (BFE). The benefits of elevating a structure are to minimize the threat for future flood losses to property and personal belongings; in addition, the activity provides peace of mind to homeowners who have elevated above most flooding events.

3.0 MANDATORY ELEVATION

All communities that participate in the National Flood Insurance Program (NFIP) are required to develop a local Floodplain Management Ordinance. These ordinances identify minimum standards that, when met, require homeowners to elevate their houses.

Substantial Damage- after a flood or other damaging event, the Floodplain Administrator for the community will assess damaged structu res.

Residential structures that have sustained a 50% or greater loss of the value of the structure (not including lot) are deemed substantially-damaged, and prior to obtaining a building permit, the owners must agree to bring the structure up to the NFI P standard of being elevated to the BFE (or higher as required by local code).

In some instances, communities add 2' of freeboard above the BFE to provide additional flood safety value. The Floodplain Administrator will provide the homeowner with a copy of a letter that states that the property is substantially-damaged.

4.0 TYPES OF ELEVATIONS:

Available elevation methods, which are thoroughly described in FEMA P-312, Chapter 5, and FEMA P-347 include:

4.1 Elevating the existing structure on piles, posts, or piers

4.1.1 Elevations in V zones (Velocity Zones in Coastal High Hazard Areas) must be on open foundations. The lowest floor m ust be free of obstructions or constructed with non-supporting breakaway walls, open wood lattice work, or screening intended to collapse under wind and water loads without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system.

4.2 Filling in the basement and replacing it with an elevated floor

4.3 Elevating by vertically extending the foundation walls of the home

4.4 The method that is selected for elevating a house depends on factors such as:

4.4.1 Foundation type

4.4.2 Condition of the house

4.4.3 Applicable state and local building codes

4.4.4 Soil type and bearing capacity

4.4.5 Weight of the house and lateral forces on the house from water and other natural hazards, such as winds and earthquakes

4.4.6 Height of proposed elevation above the grade level

4.4.7 Number of additions to the original structure

5.0 ELEVATION REQUIREMENTS:

5.1 Foundations must be designed to properly address all loads and be appropriately connected to the floor structure above, and utilities m ust also be properly elevated.

5.2 Elevations must comply with NFI P standards and building codes that exist in the State and community. Elevations must comply with ASCE24-14 or latest edition.

5.3 Elevation must be designed and adequately anchored to prevent flotation, collapse, and lateral movement due to hydrodynamic and hydrostatic loads, including the effects of buoyancy. ·

5.4 A building permit is required in order to elevate.

6.0 STRUCTURAL SOUNDNESS:

Structures must be structurally sound and capable of being elevated safely. Prior to participating in a FEMA Grant Program project to elevate houses, homeowners will have an inspection by a licensed structural engineer that determines whether a house can successfully be elevated or not.
