The flood hazard areas of the City are subject to periodic inundation which may result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. B. These flood losses may be caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities and, when inadequately anchored, cause damage in other areas. Uses that are inadequately flood proofed, elevated or otherwise protected from flood damage, also contribute to the flood loss. SECTION 1.03 STATEMENT OF PURPOSE It is the purpose of this Article 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: A. Protect human life and health; B. Minimize expenditure of public money for costly flood control projects; C. Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; D. Minimize prolonged business interruptions; E. Minimize damage to public facilities and utilities such as water and gas mains; electric, telephone and sewer lines; and streets and bridges located in areas of special flood hazard; F. Help maintain a stable tax base by providing for the sound use and development of areas of special flood hazard so as to minimize blight areas caused by flooding; 4 G. Ensure that potential buyers are notified that property is in an area of special flood hazard; H. Ensure that those who occupy the areas of special flood hazard assume responsibility for their actions; I. Maintain eligibility for disaster relief. SECTION 1.04 METHODS OF REDUCING FLOOD LOSSES In order to accomplish its purposes, this Article includes methods and provisions to: A. Restrict or prohibit uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or flood heights or velocities; B. Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; C. Control the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel floodwaters; D. Control filling, grading, dredging, and other development which may increase flood damage; and E. Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards in other areas.

Governing body.The Mayor and City Council of the City of Apache Junction. Hardship.As referenced in this Article, the exceptional hardship that would result from a failure to grant the requested variance. The variance shall be 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.The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure. Historic structure.Any structure that is: 1. 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; 10 2.

The term "manufactured home" does not include a "recreational vehicle". 11 Manufactured Home Park or Subdivision.A parcel (or contiguous parcels) of land divided into two or more manufactured home lots for rent or sale. Market value."Market value" shall be determined by estimating the cost to replace the structure in new condition and adjusting that cost figure by the amount of depreciation which has accrued since the structure was constructed. A.The cost of replacement of the structure shall be based on a square foot cost factor determined by reference to a building cost estimating guide recognized by the building construction industry. B.The amount of depreciation shall be determined by taking •into account the age and physicaLdeterioration of the structure and functional obsolescence as approved by the floodplain administrator, but shall not include 'economic or other forms of external obsolescence. Use of replacement costs or accrued depreciation factors different from those contained in recognized building cost estimating guides may be considered only if such factors are included in a report prepared by an independent professional appraiser and supported by a written explanation of the differences..

Start of construction.Includes substantial improvement and other proposed new development and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days from the date of the permit. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of 14 excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include 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 accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. 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.A walled and roofed building that is principally above ground; this includes a gas or liquid storage tank or a manufactured home. Substantial damage.Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred; or 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 event, on the average, equals or exceeds 25 percent of the market value of the structure before the damage occurred. This is also known as "repetitive loss." Substantial improvement.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.

SECTION 3.01 LANDS TO WHICH THIS ARTICLE APPLIES This Article shall apply to all areas of special flood hazards within the corporate limits of the City. SECTION 3.02 BASIS FOR ESTABLISHING THE AREAS OF SPECIAL FLOOD HAZARD The areas of special flood hazard identified by FEMA in a scientific and engineering report entitled "The Flood Insurance Study ("FIS") for the City dated March 30, 1982", with accompanying Flood Insurance Rate Maps ("FIRMs") and Flood Boundary and Floodway Maps ("FBFMs") revised March 19, 1990, and all subsequent amendments and/or revisions, are hereby adopted by reference and declared to be a part of this Article. This FIS and attendant mapping is the minimum area of applicability of this Article and may be supplemented by studies for other areas which allow implementation of this Article and which are recommended to the Floodplain Board by the Floodplain Administrator. The Floodplain Board shall delineate (or may, by rule, require developers of land to delineate) for areas where development is ongoing or imminent, and thereafter as development becomes imminent, floodplains consistent with the criteria developed by FEMA and the Director of ADWR. The FIS and 16 FIRM panels are on file at the Department of Public Works at 575 E. Baseline Avenue, Apache Junction, Arizona, or any other location deemed by the City Manager as an appropriate filing location in the event the Public Works yard is moved. SECTION 3.03 COMPLIANCE All development of land, construction of residential, commercial or industrial structures, or future development within delineated floodplain areas is subject to the terms of this Article and other applicable regulations. SECTION 3.04 ABROGATION AND GREATER RESTRICTIONS This Article is not intended to repeal, abrogate or impair any existing easements, covenants or deed restrictions. However, where this Article and any ordinance, easement, covenant or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.

Liberally construed in favor of the governing body; and C. Deemed neither to limit nor repeal any other powers granted under state statutes. SECTION 3.06 DISCLAIMER OF LIABILITY The degree of flood protection required by this Article is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This Article does not imply that land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This Article shall not create liability on the part of the City, any officer or employee thereof, the State of Arizona, 17 or FEMA, for any flood damages that result from reliance on this Article or any administrative decision lawfully made hereunder. SECTION 3.07 STATUTORY EXCEPTIONS In accordance with A.R.S. § 48-3609(H), unless expressly provided, this and any regulation adopted pursuant: to this Article do not affect: A. Existing legal uses of property or the right to continuation of such legal use.

SECTION 5.02 STANDARDS FOR STORAGE OF MATERIALS AND EQUIPMENT A. The storage or processing of materials that could be injurious to human, animal or plant life if released due to damage from flooding is prohibited in special flood hazard areas. B. Storage of other material or equipment may...be allowed if not subject to damage by floods and if firmly anchored to prevent flotation, or if readily removable from the'area within the time available after flood warning. SECTION 5.03 STANDARDS FOR UTILITIES A. All new or replacement water supply and sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharge from systems into flood waters. B. On -site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. C. Waste disposal systems shall not be installed wholly or partially in a regulatory floodway. 30 SECTION 5.04 ADDITIONAL DEVELOPMENT STANDARDS, INCLUDING SUBDIVISIONS A. All new subdivision proposals and other proposed development (including proposals for manufactured home parks and subdivisions), greater than 50 lots or 5 acres, whichever is the lesser, shall: 1. Identify the area of the special flood hazard area and the elevation of the base flood. 2. Identify on the final plans the elevation(s) of the proposed structure(s) and pads. If the site is filled above the base flood elevation, the final lowest floor and grade elevations shall be certified by a registered professional engineer or surveyor and provided to the Floodplain Administrator. B. All subdivision proposals and other proposed development shall be consistent with the need to minimize flood damage. C. All subdivision proposals and other proposed development shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage.

Meet the permit requirements of this Article and the elevation and anchoring requirements for manufactured homes in this Article. SECTION 5.07 FLOODWAYS Located within areas of special flood hazard established in this Article are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles and erosion potential, the following provisions apply: A. Prohibit encroachments, including fill, new construction, substantial improvements and other development, unless certification by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. B. If this provision is satisfied, all new construction and substantial improvements shall comply with all other applicable flood hazard reduction provisions of this Article. SECTION 6.01 NATURE OF VARIANCES The variance criteria set forth in this section of the Article are based on the general principle of zoning law that variances pertain to a piece of property and are not personal in nature. A 32 variance may be granted for a parcel of property with physical characteristics so unusual that complying with the requirements of this Article would create an, exceptional hardship to the applicant or the surrounding property owners. The characteristics must be unique to the property and not be shared by adjacent parcels. The unique characteristic must pertain to the land itself, not to the structure, its inhabitants or the property owners. It is the duty of the City to help protect its citizens from flooding. This need is so compelling and the implications of the cost of insuring a structure built below the regulatory flood elevation are so serious that variances from the flood elevation or from other requirements in the flood ordinance are quite rare. The long-term goal of preventing and reducing flood loss and damage can only be met if variances are strictly limited. Therefore, the variance guidelines provided in this Article are more detailed and contain multiple provisions that must be met before a variance can be properly granted. The criteria are designed to screen out those situations in which alternatives other than a variance are more appropriate. 6.02 APPEAL BOARD A. The Floodplain Board of the City shall hear and decide appeals and requests for variances from the requirements of this Article. B. The Floodplain Board shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the Floodplain Administrator in the enforcement or administration of this Article. C. In passing upon such applications, the Floodplain Board shall consider all technical evaluations, all relevant factors, standards specified in other sections of this Article, and: 1. The danger that materials may be swept onto other lands to the injury of others; 2. The danger of life and property due to flooding or erosion damage; 33 3. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; 4. The importance of the services provided by the proposed facility to the community; 5. The necessity to the facility of a waterfront location, where applicable; 6. The availability of alternative locations for the proposed use, which are not subject to flooding or erosion damage; 7. The compatibility of the proposed use with existing and anticipated development; 8. The relationship of the proposed use to the comprehensive plan and floodplain management program for that area; 9. The safety of access to the property in time of flood for ordinary and emergency vehicles; 10. The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters expected at the site; and, 11. The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, water system and streets and bridges. D. Upon consideration of the factors and the purposes of this Article, the Floodplain Board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this Article. E. Any applicant to whom a variance is granted shall be given written notice over the signature of a community official that: 1. The issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25 for $100 of insurance coverage, and 34 2. Such construction below the base flood level increases risks to life and property; and 3. The land upon which the variance is granted shall be ineligible for exchange of state land pursuant to the flood relocation and land exchange program provided by A.R.S. Title 26, Chapter 2, Article 2. A copy of the notice shall be recorded in the office of the Final County Recorder and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land. F. The Floodplain Administrator shall maintain a record of all variance actions, including justification for their issuance and report such variances issued in its biennial report submitted to FEMA. SECTION 6.03 CONDITIONS FOR VARIANCES A. Generally, variances 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 elevation, provided the procedures of this Article have been fully considered. As the lot size increases beyond one-half acre, the technical justification required for issuing the variance increases. B. Variances may be issued for the repair, rehabilitation or restoration of structures listed in the National Register of Historic Places or the State Inventory of Historic Places, upon a determination that the proposed repair or rehabilitation will not preclude the structures continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure. C. Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. D. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. 35 E. Variances shall only be issued upon a: 1. Showing of good and sufficient cause; and 2. Determination that failure to grant the variance would result in exceptional hardship to the applicant; and 3. Showing that the use cannot perform its intended purpose unless it is located or carried out in close proximity to water. This includes only facilities defined in Section 2.01 in the definition of "Functionally dependent use"; and 4. Determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public or conflict with existing local laws or ordinances. 36 SECTION 1.01 SECTION 2.01 SECTION 2.02 SECTION 3.01 SECTION 3.02 SECTION 3.03 SECTION 3.04 SECTION 3.05 SECTION 4.01 SECTION 4.02 SECTION 4.03 SECTION 5.01 SECTION 1.01 ARTICLE II STORMWATER REGULATIONS DEFINITIONS ILLICIT DISCHARGES TO THE STORMWATER SYSTEM PROHIBITED NON-STORMWATER DISCHARGES INTENT AND PURPOSE REQUIREMENT FOR APPROVED STORMWATER POLLUTION PREVENTION PLANS REQUIREMENT TO INSTALL AND MAINTAIN EROSION PREVENTION AND SEDIMENT CONTROL MEASURES REQUIREMENT TO CONTROL CONSTRUCTION AND SANITARY WASTE RIGHT OF ENTRY; CONSTRUCTION SITE INSPECTIONS INTENT AND PURPOSE REQUIREMENT TO IMPLEMENT AND MAINTAIN POST- CONSTRUCTION STORMWATER MEASURES RIGHT OF ENTRY; POST CONSTRUCTION INSPECTIONS VIOLATIONS • DEFINITIONS For the purposes of this Article, the following definitions apply: Arizona Department of Environmental Quality or "ADEQ".The Arizona state agency established pursuant to Arizona Revised Statutes § 49-102.
