Page 1 FLOOD DAMAGE PREVENTION ORDINANCE City of Prichard Ordinance #_ Qpx]3 ARTICLE 1 Statutory Authorization, Findings of Fact, Purpose And Objectives SECTION A STATUTORY AUTHORIZATION The Legislature of the State of Alabama has in Title 11, Chapter 19, Sections 1-24, Chapter 45, Sections 1-11, Chapter 52, Sections 1-84, and Title 41, Chapter 9, Section 166 of the Code of Alabama, 1975, authorized local government units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, the City Council, of City of Prichard, Alabama, does ordain as follows: SECTION B FINDINGS OF FACT (1) The flood hazard areas of Prichard, Alabama are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood relief and protection, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. (2) These flood losses are caused by the occupancy in flood hazard areas of uses vulnerable to floods, which are inadequately elevated, flood proofed, or otherwise unprotected from flood damages, and by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities. SECTION C STATEMENT OF PURPOSE It is the purpose of this ordinance to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: (1) require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (2) restrict or prohibit uses which are dangerous to health, safety and property due to water or erosion hazards, or which increase flood heights, velocities, or erosion; Page 2 FLOOD DAMAGE PREVENTION ORDINANCE © G) control filling, grading, dredging and other development which may increase flood damage or erosion; (4) __ prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands; and (5) control the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of flood waters. SECTION D OBJECTIVES The objectives of this ordinance are: (1) to protect human life and health; (2) to minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; (3) to help maintain a stable tax base by providing for the sound use and development of flood prone areas in such a manner as to minimize flood blight areas, (4) to minimize expenditure of public money for costly flood control projects; (5) to minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (6) to minimize prolonged business interruptions, and (7) to ensure that potential home buyers are notified that property is in a flood area, ARTICLE 2 GENERAL PROVISIONS SECTION A LANDS TO WHICH THIS ORDINANCE APPLIES This ordinance shall apply to all Areas of Special Flood Hazard within the jurisdiction of City of Prichard, Alabama. SECTION B BASIS FOR AREA OF SPECIAL FLOOD HAZARD The Areas of Special Flood Hazard identified by the Federal Emergency Management Agency in its Flood Insurance Study (FIS), dated June 5, 2020, with accompanying maps and other supporting 2/7/2019 pg] 2 Page 3 Ne, FLOOD DAMAGE PREVENTION ORDINANCE data and any revision thereto, are adopted by reference and declared a part of this ordinance. For those land areas acquired by a municipality through annexation, the current effective FIS and data for Mobile County are hereby adopted by reference. Areas of Special Flood Hazard may also include those areas known to have flooded historically or defined through standard engineering analysis by governmental agencies or private parties but not yet incorporated in the FIS. When Preliminary Flood Insurance Studies and Flood Insurance Rate Maps have been provided by FEMA to the City of Prichard: (L) Prior to the issuance of a Letter of Final Determination (LFD) by FEMA, the use of the preliminary flood hazard data shall only be required where no base flood elevations and/or floodway areas exist or where the preliminary base flood elevations or floodway area exceed the base flood elevations and/or floodway widths in the effective flood hazard data provided by FEMA. Such preliminary data may be subject to revision through valid appeals. (2) Upon the issuance of a Letter of Final Determination (LFD) by FEMA, the revised flood hazard data shall be used and replace all previously effective flood hazard data provided by FEMA for the purposes of administrating these regulations. Where adopted regulatory standards conflict, the more stringent base flood elevation shall prevail. Preliminary FIS data may be subject to change by a valid appeal. SECTION C: ESTABLISHMENT OF A FLOODPLAIN DEVELOPMENT PERMIT A Development Permit shall be required in conformance with the provisions of this ordinance PRIOR to the commencement of any development activities in identified areas of special flood hazard and community flood hazard areas within the community. SECTION D. COMPLIANCE No structure or land shall hereafter be located, extended, converted or altered without full compliance with the terms of this ordinance and other applicable regulations. SECTION E. ABROGATION AND GREATER RESTRICTIONS This ordinance is not intended to repeal, abrogate, or impair any existing ordinance, easements, covenants, or deed restrictions.

Accessory Structures (also referred to as appurtenant structures) — This provision generally applies to new and substantially improved accessory structures. When an accessory structure complies with all other provisions of this ordinance (including floodway encroachment), represents a minimal investment (less than $1,000), and meets the requirements outlined below, these structures may be wet-floodproofed and do not have to be elevated or dry floodproofed. Accessory structures include, but are not limited to, residential structures such as detached garages, storage sheds for garden tools or woodworking, gazebos, picnic pavilions, boathouses, small pole barns, and similar buildings. The following provisions apply to accessory structures built below the base flood elevation: (a) | A permit shall be required prior to construction or installation. (b) = Must be low value (less than $1,000) and not be used for human habitation. (c) | Use must be restricted to parking of personal vehicles or limited storage (low-cost items that cannot be conveniently stored in the principal structure). (d) Must be designed with an unfinished interior and constructed with flood damage- resistant materials below the BFE. (ec) Must be adequately anchored to prevent flotation, collapse, or lateral movement. @® Must have adequate flood openings as described in Article 4, Section A (5) and be designed to otherwise have low flood damage potential. (g) Shall be constructed and placed on the building site so as to offer the minimum resistance to the flow of floodwaters. 2/7/2019 pg | 15 Page 16 FLOOD DAMAGE PREVENTION ORDINANCE (h) — Any mechanical and other utility equipment in the structure must be elevated to or above the BFE or must be floodproofed. @ Under limited circumstances communities may issue variances to permit construction of wet-floodproofed accessory structures. Communities should not grant variances to entire subdivisions for accessory structures, especially detached garages. Variances should only be reviewed and issued on an individual or case-by- case basis and be based on the unique characteristics of the site. SECTION C FLOODWAYS Located within Areas of Special Flood Hazard established in Article 2, Section B, are areas designated as floodway. A floodway may be an extremely hazardous area due to velocity floodwaters, debris or erosion potential. In addition, the area must remain free of encroachment in order to allow for the dischargé of the base flood without increased flood heights. Therefore, the following provisions shall apply: (1) The community shall select and adopt a regulatory floodway based on the principle that the area chosen for the regulatory floodway must be designed to carry the waters of the base flood, without increasing the water surface elevation of that flood more than one foot at any point; (2) Encroachments are prohibited, including fill, new construction, substantial improvements or other development within the adopted regulatory floodway. Development may be permitted however, provided it is demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that’ the encroachment shall not result in any increase‘in flood levels or floodway widths during a base flood discharge. A registered professional engineer must provide supporting technical data and certification thereof; (3) | Acommunity may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first applies for a conditional letter of map revision (CLOMR) and floodway revision, fulfills the requirements for such revisions as established under the provisions of § 65.12, and receives the approval of FEMA; (4) ONLY if Article 4, Section C, provisions (1) through (3) are satisfied, then any new construction or substantial improvement shall comply with all other applicable flood hazard reduction provisions of Article 4. (2) Encroachments, including fill, new construction, placement of manufactured homes, substantial improvements, and other development, are prohibited.

VARIANCES FOR HISTORIC STRUCTURES Variances may be issued for the repair or rehabilitation of Historic Structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a Historic Structure and the variance is the minimum to preserve the historic character and design of the structure. SECTION E. CONDITIONS FOR VARIANCES The provisions of this Ordinance are minimum standards for flood loss reduction, therefore any deviation from the standards must be weighed carefully. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (1) A variance may be issued for new construction and substantial improvements to be erected on a lot of one-half acre or less in size, contiguous to and surrounded by lots with existing structures constructed below; the base flood level, in conformance with the procedures of Sections E(3), E(4), F(1) and F(2) of this Article. (2) In the instance of a Historic Structure, a determination is required that the variance is the minimum necessary so as not to destroy the historic character and design of the building. QO (3) A variance shall be issued ONLY when there is: (a) A finding of good and sufficient cause; 2/7/2019 pg | 22 Page 22 FLOOD DAMAGE PREVENTION ORDINANCE (b) A determination that failure to grant the variance would result in exceptional hardship; and (c) A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances. | (4) _ A variance shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

VARIANCE NOTIFICATION AND RECORDS (1) Any applicant to whom a variance is granted shall be given written notice over the signature of a community official that specifies the difference between the base flood elevation and the -elevation of the proposed lowest floor and stating that the issuance of such a variance could: a, result in rate increases in the hundreds and possibly thousands of dollars annually depending on structure and site-specific conditions; and b. increase the risk to life and property resulting from construction below the base flood level. (2) The Floodplain Administrator shall maintain a record of all variance actions and appeal actions, including justification for their issuance. Report any variances to the Federal Emergency Management Agency Region 4 and the Alabama Department of Economic and Community Affairs/Office of Water Resources upon request. (3) | Acopy of the notice shall be recorded by the Floodplain Administrator in the Office of the City Clerk or Flood Plain Administrator City of Prichard and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land. ARTICLE 6 DEFINITIONS Unless specifically defined below, words or phrases used in this ordinance shall be interpreted so as to give them the meaning they have in common usage and to give this ordinance its most reasonable application. A Zone means the Area of Special Flood Hazard without base flood elevations determined. Accessory Structure (also referred to as appurtenant structures) means a structure which is located on the same parcel of property as a principal structure to be insured and the use of which is 2/7/2019 pg | 22 Page 23 FLOOD DAMAGE PREVENTION ORDINANCE incidental to the use of the principal structure. They should constitute a minimal initial investment, may not be used for human habitation, and be designed to have minimal flood damage potential. These structures are used solely for parking (two-car detached garages or smaller) or limited. storage (small, low cost storage sheds). They are included under the general definition of structure and are consequently subject to all floodplain management regulations pertaining to structures. Addition (to an existing building) means any improvement that increases the square footage of a structure. These include lateral additions added to the front, side, or rear of a structure, vertical additions added on top of a structure, and enclosures added underneath a structure. NFIP regulations for new construction apply to any addition that is considered a perimeter expansion or enclosure beneath a structure. If it is considered to be a substantial improvement (more than 50% of market value) to a structure, the existing structure will also need to be treated as new construction. Depending on the flood zone and details of the project, the existing building may not have to be elevated. The determining factors are the common wall and what improvements are made to the existing structure. If the common wall is demolished as part of the project, then the entire structure must be elevated. If only a doorway is knocked through it and only minimal finishing is done, then only the addition has to be elevated. AE Zone means the Area of Special Flood Hazard with base flood elevations determined. AH Zone means an area of one Fervent chance of shallow flooding where depths are between one to three feet (usually shallgw ponding), with base flood elevations shown. AO Zone means an area of one percent chance of shallow flooding where depths are between one to three feet (usually sheet flow on sloping terrain), with depth numbers shown. ‘Appeal means a request for a review of the Board of Adjustment interpretation of any provision of this ordinance. AR/AE, AR/AH, AR/AO, and AR/A Zones means a flood zone that results from the decertification of a previously accredited flood protection system or levee that is in the process of being restored to provide a one percent chance or greater level of flood protection. Afier restoration is complete, these areas will still experience residual flooding from other flooding sources. A99 Zone means that part of the special flood hazard area inundated by the one percent annual chance flood to be protected from the one percent chance flood by a Federal flood protection system or levee under construction, no base flood elevations are determined. Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with base flood depths from one to three feet, and/or where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate, and where velocity flow may be evident. 2/7/2019 . pg | 23 Page 24 FLOOD DAMAGE PREVENTION ORDINANCE Area of special flood hazard (also see “Special flood hazard area”) means the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year.

Base fiood means the flood having a one percent chance of being equaled or exceeded in any given year (also referred to as the “one percent chance flood”). Base flood elevation means the computed elevation to which floodwater is anticipated to rise during the base flood. It is also the elevation of surface water resulting from a flood that has a 1% chance of equaling or exceeding that level in any given year. Base Flood Elevations are shown in the FIS and on the Flood Insurance Rate Map (FIRM) for zones AE, AH, A1—A30, AR, AR/A, AR/AE, AR/Ai— A30, AR/AH, AR/AO, V1—V30 and VE. Basement means any portion of a building having its floor sub grade (below ground level) on all sides. Building (also see Structure) means (1) A structure with 2 or more outside rigid walls and a fully secured roof, that is affixed to a permanent site; or (2) a manufactured home (a “manufactured home,” also known as a mobile home, is a structure built on a permanent chassis, transported to its site in 1 or more sections, and affixed to a permanent foundation); or (3) a travel trailer without wheels, built on a chassis and affixed to a permanent foundation, that is regulated under the community’s floodplain management and building ordinances or laws.

Critical facility (aka, critical action) means facilities for which the effects of even a slight chance of flooding would be too great. The minimum floodplain of concern for critical facilities is the 0.2 percent chance flood level. Critical facilities include, but are not limited to facilities critical to the health and safety of the public such as: emergency operations centers, designated public shelters, schools, nursing homes, hospitals, police, fire and emergency response installations, vital data storage centers, power generation and water and other utilities (including related infrastructure such as principal points of utility systems) and installations which produce, use or store hazardous materials or hazardous waste (as defined under the Clean Water Act and other Federal statutes and regulations).

Mudslides which are proximately caused by flooding as described in part “b.” of this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current. d. The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually highwater level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in part “a.” of this definition. Flood Hazard Boundary Map (FHBM) means an official map of a community, issued by the Federal Insurance Administration, where the boundaries of areas of special flood hazard have been designated as Zone A. peop Flood Insurance Rate Map (FIRM) means an official map of a community, on which the Federal Emergency Management Agency has delineated the areas of special flood hazard and/or risk premium zones applicable to the community. Flood Insurance Study/ Flood Elevation Study means an examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations, or an examination, evaluation and determination of mudslide and/or flood-related erosion hazards. loodplain means any land area susceptible to being inundated by water from any source. Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain management regulations, and open space plans. Floodplain management regulations means this ordinance and other zoning ordinances, S subdivision regulations, building codes, health regulations, special purpose ordinances, and other applications of police power which control development in flood-prone areas. This term describes federal, state, or local regulations in any combination thereof, which provide standards for preventing and reducing flood loss and damage. Floodprocfing means any combination of structural and nonstructural additions, changes or adjustments to structures, which reduce or eliminate risk of flood damage to real estate or improved real property, water and sanitation facilities or structures with their contents. Floodway (Regulatory Fleodway) means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. 2/7/2019 pg | 26 Page 27 O FLOOD DAMAGE PREVENTION ORDINANCE Floodway fringe means that area of the special flood hazard area on either side of the regulatory floodway. XX Flood Protection Elevation means the base flood elevation plus the community freeboard. In areas where no base flood elevations exist from any authoritative source, the flood protection elevation can be historical flood elevations or base flood elevations determined and/or approved by the floodplain administrator plus freeboard. Freeboard means a factor of safety usually expressed in feet above the Base Flood Elevation (BFE) for purposes of floodplain management which tends to compensate for the many unknown factors that could contribute to flood heights greater than the height calculated fora _ selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effect of urbanization of the watershed. Used to determine the level for a building's lowest floor elevation or level of floodproofing required to be in compliance with the community's floodplain management regulations. Functionally dependent facility means a facility which cannot be used for its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facility that are necessary for the loading and unloading of cargo or passengers, and shipbuilding, and ship repair facilities. The term does not include long-term storage or related manufacturing facilities. Hardship (as related to variances of this ordinance) means the exceptional difficulty that would result from a failure to grant the requested variance. The Board of Adjustment requires that the variance is exceptional, unusual, and peculiar to the property involved. Mere economic or financial hardship alone is NOT exceptional. Inconvenience, aesthetic considerations, physical handicaps, personal preferences, or the disapproval of one’s neighbors likewise cannot, as a rule, qualify as an exceptional hardship. All of these problems can be resolved through other means without granting a variance, even if the alternative is more expensive, or requires the property owner to build elsewhere or put the parcel to a different use than originally intended. Highest adjacent grade means the highest natural elevation of the ground surface, prior to construction, next to the proposed walls of a structure. Historic Structure means any structure that is; a. Listed individually in the National Register of Historic Places (a listing maintained by the U.S. Department of Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register: b.

Letter of Map Change (LOMO) is an official FEMA determination, by letter, to amend or revise effective Flood Insurance Rate Maps, Flood Boundary and Floodway Maps, and Flood Insurance Studies. LOMC’s are broken down into the following categories: Letter of Map Amendment (LOMA) An amendment based on technical data showing that a property was incorrectly included in a designated SFHA, was not elevated by fill (only by a natural grade elevation), and will not be inundated by the one percent chance flood. A LOMA amends the current effective FIRM and establishes that a specific property is not located in a SFHA. Letter of Map Revision (LOMR) A revision based on technical data that, usually due to manmade changes, shows changes to flood zones, flood elevations, floodplain and floodway delineations, and planimetric features, One common type of LOMR, a LOMR-F, is a determination concerning whether a structure or parcel has been elevated by fill above the BFE and is, therefore, excluded from the SFHA. Conditional Letter of Map Revision (CLOMR) 4 formal review and comment by FEMA as to whether a proposed project complies with the minimum NFIP floodplain management criteria. A CLOMR does not revise effective Flood Insurance Rate Maps, Flood Boundary and Floodway Maps, or Flood Insurance Studies. Levee means a man-made structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to provide protection from temporary flooding. [only required in communities with levees] Levee System means a flood protection system which consists of a levee, or levees, and associated structures, such as closure and drainage devices, which are constructed and operated in accordance with sound engineering practices. [only required in communities with levees] Lowest adjacent grade means the point of the ground leyel immediately next to a building. This may be the sidewalk, patio, deck support, or basement entryway immediately next to the structure after the completion of construction.

One Percent Flood (aka 100-Year Flood) is the flood that has a one percent chance of being equaled or exceeded in any given year. Any flood zone that begins with the letter A or V is subject.to inundation by the one percent chance flood. Over the life of a 30-year loan, there is a 26-percent chance of experiencing such a flood within the SFHA. Participating Community is any community that voluntarily elects to participate in the NFIP by adopting and enforcing floodplain management regulations that are consistent with the standards of the NFIP.

Regulatory floodway see Floodway. 2/7/2019 pg | 30 Page 31 FLOOD DAMAGE PREVENTION ORDINANCE Remedy a violation means to bring the structure or other development into compliance with State or local floodplain management regulations, or, if this is not possible, to reduce the impacts of its noncompliance. Ways that impacts may be reduced include protecting the structure or other affected development from flood damages, implementing the enforcement provisions of the ordinance or otherwise deterring future similar violations, or reducing Federal financial exposure with regard to the structure or other development. \ Repetitive Loss means flood-related damages sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on the average, equals or exceeds 25 percent of the market value of the structure before the damages occurred. \ Repetitive Loss Property means any insurable structure for which two or more claims of more than $1,000 were paid by the National Flood Insurance Program (NFIP) within any rolling 10-year period, since 1978, At least two of the claims must be more than ten (10) days apart but, within ten years of each other. A repetitive loss property may or may not be currently insured by the NFIP. Section 1316 means no new flood insurance policy or federal disaster assistance shall be provided for any property which the Administrator finds has been declared by a duly constituted State or local zoning authority or other authorized public body, to be in violation of State or local laws, regulations or ordinances which are intended to discourage or otherwise restrict land development or occupancy in floodprone areas. If the structure is made compliant with the applicable community’s floodplain management ordinance, then the Section 1316 declaration can be rescinded by the community and flood insurance and disaster assistance eligibility restored. Severe Repetitive Loss Structure means any insured property that has met at least one of the Sollowing paid flood loss criteria since 1978, regardless of ownership: a. Four or more separate claim payments of more than $5,000 each (including building and contents payments); or b. Two or more separate claim payments (building payments only) where the total of the payments exceeds the current market value of the property.

Multiple losses at the same location within ten days of each other are counted as one loss, with the payment amounts added together. Special flood hazard area (SFHA) means that portion of the floodplain subject to inundation by the base flood and/or flood-related erosion hazards as shown on a FHBM or FIRM as Zones A, AE, AH, AO, AR, AR/AE, AR/AO, AR/AH, AR/A, A99, or VE. Start of construction (for other than new construction or substantial improvements under the Coastal Barrier Resources Act (Pub. L. 97-348)) means the date the development or building permit was issued (includes substantial improvement), provided the actual start of construction, repair, reconstruction, or improvement was within 180 days of the permit date. The actual start means the first placement of permanent construction of the structure (including a manufactured home) on a 2/7/2019 pg} 31 Page 32 FLOOD DAMAGE PREVENTION ORDINANCE ‘ site, such as the pouring of slabs or footings, installation of piles, construction of columns, or any work beyond the stage of excavation, and includes the placement of a manufactured home on a foundation. “Permanent construction” does not include initial land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the property of buildings appurtenant to the permitted structure, such as garages or sheds not occupied as dwelling units or part of the main structure. (VOTE: accessory structures are NOT exempt from any ordinance requirements). For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building. Structure means a walled and roofed building, including a liquid or gas storage tank, that is principally above ground, as well as a manufactured home. Substantial damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to it before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. Substantial damage also means flood related damages sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on the average, equals or exceeds 25 percent of the market value of the structure before the damages occurred. [OR replace the “50 percent” and “25 percent” with lower values for stricter standards] Substantial improvement means any reconstruction, rehabilitation, addition, or other improvement ofa structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement. This term includes structures which have incurred “repetitive loss” or “substantial damage”, regardless of the actual repair work performed. The market value of the building should be (1) the appraised value of the structure prior to the start of the initial repair or improvement, or (2) in the case of damage, the value of the structure prior to the damage occurring. If lower values are used in the above definition for “Substantial damage”, then include the same lower values for stricter standards for this defintion] [OR replace “means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement” with the following:] means any combination of reconstruction, alteration, or improvement to a building, taking place during a 5-year [or 10-year] period, in which the cumulative percentage of improvement equals or exceeds 50 percent of the current market value of the structure before the “start of construction” of the initial improvement. Any subsequent improvement project costs shall be added to the initial costs for the initial improvement project. At the end of a 5-year [or 10-year] period from the initial improvement project, an updated valuation for the structure can be used for the next time period. For the purposes of this definition, substantial 5 1 12 1 1 8 784 1920 189 32 96.269081 improvement is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or 2/7/2019 pg | 32 Page 33 FLOOD DAMAGE PREVENTION ORDINANCE not that alteration affects the external dimensions of the building. The term does not, however, include either: a. Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions (provided that said code deficiencies were not caused by neglect or lack of maintenance on the part of the current or previous owners) or; b. Any alteration of a “historic structure”, provided that the alteration will not preclude the structure’s continued designation as a “historic structure”. Substantially improved existing manufactured home parks or subdivisions is where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds 50 percent of the value of the streets, utilities and pads before the repair, reconstruction or improvement commenced. [fflower values are used in the definition above for “Substantial improvement”, then include the same lower values for stricter standards for this definition] .

Wet floodproofing means a method of construction which allows water to enter a structure in such a way that will minimize damage to the structure and its contents. Wet floodproofing is appropriate Jor functionally dependent use and uses that facilitate open space use by variance only, structures utilized for parking or limited storage, or when all other techniques are not technically feasible. Wet floodproofing shall not be utilized as a method to satisfy the requirements of this ordinance for bringing substantially damaged or improved structures into compliance. Wet floodproofing is not allowed in lieu of complying with the lowest floor elevation requirements for new residential buildings. 2/7/2019 pe | 33 Page 34 = FLOOD DAMAGE PREVENTION ORDINANCE X Zones (shaded) are areas of 0.2 percent chance flood that are outside of the SFHA subject to the one percent chance flood with average depths of less than one foot, or with contributing drainage area less than one square mile, and areas protected by certified levees from the base flood. f X Zones (unshaded) are areas determined to be outside the 0.2 percent chance floodplain. Zone means a geographical area shown on a Flood Hazard Boundary Map or a Flood Insurance Rate Map that reflects the severity or type of flooding in the area.
