HARDSHIP RELIEF PROCEDURES 103.1 Types of Relief Requests (1) A hardship may exist which necessitates the granting of a variance where the strict application of one or more requirements of this Code would render a parcel incapable of reasonable economic use. Specified provisions set forth in this Code may be waived or varied where, because of the particular physical surroundings, shape or topographical condition of the property, compliance would result in a particular hardship upon the owner. A hardship is distinguished from a mere inconvenience or a desire to make more money. The application for hardship relief shall provide facts and evidence sufficient to enable the Commission to make findings in compliance with the criteria set forth in this section, and to avoid conflict with the Comprehensive Plan. (2) A decision on issuance of a development permit may be appealed to the Commission by a developer by filing an appeal with the City within ten working days of the decision. The notice of appeal shall indicate the nature of the interpretation that is being appealed. The matter at issue will be a determination of the appropriateness of the interpretation of the requirements of the Code. The appealing party assumes the responsibility of all required notification procedures (see section 103.3). (3) Final determination of a hardship relief decision is vested in the Commission as provided for in this section. 103.2 Responsibility of the Commission (1) The Commission shall have the following powers: (a) To hear and decide appeals where it is alleged there is error in any order, requirement, decision or determination made by an administrative official in the enforcement of any Development Code provision. (b) To authorize hardship relief from the terms of the Code. (2) In exercising their powers the Commission may, in conformity with the provisions of this Code or referenced codes, reverse or affirm, wholly or partly, or modify the order, requirement, decision or determination appealed from and may make such order, requirement, decision or determination as ought to be made, and to that end shall have all the powers of the officer from whom the appeal is taken. (3) Hardship relief from the terms of this Code may be granted, only upon written findings by the Commission that all of the following are met: (a) Special conditions and circumstances exist which are peculiar to the land, structure, or building involved and which are not applicable to other lands, structures, or buildings. (b) The special conditions and circumstances do not result from the actions of the developer, nor could the condition or circumstances be corrected or avoided by the developer. (c) The relief granted is the minimum degree of relief necessary to make possible the reasonable use of the land, building, or structure in compliance with all other applicable regulations. (d) Literal interpretation of the provisions of the Code would deprive the developer of rights commonly enjoyed by other properties under the terms of this Code and would work unnecessary and undue hardship on the developer. (e) The grant of the relief will not violate the general intent and purpose of this Code nor policies of the Comprehensive Plan. (f) The grant of relief will not create unsafe conditions nor other detriments to the public welfare beyond the effects of development otherwise allowed. (4) In granting any hardship relief, the Commission may prescribe appropriate conditions and safeguards in conformity with this Code. Violation of the terms of such conditions and safeguards, when made a part of the term of the development permits or final plat shall be deemed a violation of this Code. 103.3 Hearing Procedures (1) A public hearing shall be held on the request for hardship relief at the next available Commission meeting after submittal of the request. (2) The developer shall provide adequate notice of the public hearing to adjacent property owners. Notice of a public hearing shall be reasonably calculated to give actual notice and shall consist of the following: (a) Mailed Notice The developer shall provide satisfactory evidence to the Commission of mailing the required notice to the adjacent property owners. Mailed notice shall be given at least 15 days in advance of the scheduled public hearing. Unless otherwise provided, addresses for a mailed notice required by this Code shall be obtained by the developer from the City's property tax records. All property tax owners within 200 feet and all owners of residentially-designated property within 500 feet shall be notified by mail. Unless the address is on file with the City, a person whose name is not in the tax records at the time of filing of an application, or of initiating other action not based on an application, need not be furnished mailed notice. The failure of a property owner to receive notice shall not invalidate an action if a good faith attempt was made to comply with the requirements of this section. The written notice shall contain the following information: (1) The date, time, and place of the hearing. (2) A description reasonably calculated to inform a person of the location of the property for which a permit, plat, or other action is pending, including but not limited to use of a map or postal address and a subdivision lot and block designation, a metes and bounds description or the tax map designation of the County Appraisal District. The sections of the Code that are pertinent to the hearing procedure. (3) (4) That the written documents may be examined and written comments accepted during normal business hours in the office of the Planning Department at City Hall. (b) Procedure for Posted Notice Within three (3) days of filing of a request for hardship relief, the developer shall cause to be placed on said land a sign or signs indicating the type of relief sought and the day and time of Commission review. The signs shall be placed at not more than three hundred (300) foot intervals across the property line fronting on existing streets and must be clearly visible from the street. Each sign shall be no greater than ten (10) feet from the property line and shall be no smaller than eighteen (18) inches by twenty-four (24) inches. (3) The burden of proof for approving a hardship request is upon the developer. The more drastic the request or the greater the impact of the proposal on the area, the greater is the burden upon the developer. The proposal shall be supported by proof that it conforms to the applicable elements of the Comprehensive Plan and to applicable standards of this Code. 104.

(b) For the remainder of the extension required to install the sewer or water line across the total width of the lot of the owner requesting extension, the lot owner shall pay double pro rata. This pro rata is reimbursable as provided in section 301, except for the pro rata paid on the owner's front footage (see section 301.2).

(d) In addition to the payments specified above, the lot owner or customer must pay the appropriate service connection charges before service connections can be made. (e) Should the City require sewer or water line extensions (off site or onsite) larger in size than required by the applicant, the City shall pay for that portion of material cost over and above such requirements. Also, due allowance shall be made to the owner of the development for intersections and alleys crossed, outside the development. (f) No construction shall be scheduled nor begun by the City until all extension charges have been paid to the City. (2) The owner of a development shall pay for and install all sewer and water lines and necessary appurtenances within the boundaries of the development (on-site improvements).

Water and sewer lines extended outside (off-site) or adjacent to the boundaries of the development by the developer may receive reimbursement according to the provisions of this chapter. 301. Charges for Sewer and Water Service Where an extension has occurred according to section 300, an applicant for water and /or sewer service shall pay pro rata on the cost of the applicant's front footage in addition to the service connection charge before connection is made to the sewer or water line. If the sewer or water line is within a development, however only the service connection charge shall be paid. 301.1 Reimbursement (1) Owners of lots or developments who participate under this policy in the cost of sewer or water line extensions to their lots or sites are eligible for certain reimbursement of such cost, as specified herein, from the City.

No reimbursement shall be made to a development owner for the cost of sewers or water lines within the boundaries of the development. (b) Eligible reimbursement payable under this chapter shall be paid within thirty (30) days after receipt of such sum by the City from an assessed party. (c) A lot owner will be reimbursed one -half (1/2) the amount of pro rata collected from connections to that portion of the first three hundred -foot section provided for in section 300.2 (1)(a) above, up to the boundary of the owner's lot. (d) A lot owner will be reimbursed the amount of double pro rata collected from connections to extensions in excess of the three hundred foot section provided for in section 300.2 (1)(a), up to the boundary of the owner's lot. (e) A lot owner will be reimbursed the amount of single pro rata collected for connections from owner's opposite frontage. (f) Owners of developments will be reimbursed the amount of pro rata collected from connections to boundary sewers and boundary water lines for which they have made payment. (g) An owner will never be paid more than one hundred (100) per cent of the amount actually paid by such owner for extensions along frontage other than his own property. (h) No reimbursements shall be made by the City to an owner after the end of the ten-year period of eligibility. (2) In addition to the reimbursements provided for above, the owner of a lot used for an industrial or commercial establishment, who has paid additional costs for oversized water lines, as provided in section 300.2 (1)(c), shall be eligible for additional reimbursement from water revenues from the said water line extension, in the amount of (40) per cent of the annual gross revenue of the commercial/industrial establishment, for a period of five (5) years from the date of completion of the extension, provided that the additional reimbursement shall never exceed eighty (80) per cent of the total additional cost of the extension. 301.2 Owner's Front Footage For purposes of determining pro rata charges to be paid by the owner of a lot for sewer service or water service and for which there will be no reimbursement, the owner's front footage shall be determined as follows: (1) A regular lot is generally rectangular in shape.

Front footage shall be measured along the side of the lot to which the service connection is made. CHAPTER 4. DEVELOPMENT DISTRICTS 401. ESTABLISHMENT OF DISTRICTS The City of Huntsville, Texas is hereby divided into the following general districts: Downtown and Management. These districts are described in more detail in section 402. Additionally, the following overlay districts are created: Flood Hazard District and Airport Hazard District. The development standards within these districts are described in section 403. 402. Description of Districts 402.1 Downtown District (Fire District) This district, also called the Fire District is intended as an area of high intensity use on which a full range of public facilities are found. The standards and high densities prescribed for the district are designed to optimize utilization of in-place facilities. The district is established as follows: BEGINNING at the intersection of the east line of Avenue M and the south line of 10th Street; THENCE easterly along said south line of 10th Street to the west line of Avenue J; THENCE southerly along said west line of Avenue J to the north line of 13th Street; THENCE westerly along said north line of 13th Street to the east line of Avenue M; THENCE northerly along east line of Avenue M to the point of beginning. 402.2 Management District The Management District is the principal district in the City. All land not specifically designated within the Downtown District is designated as part of the Management District. All land uses are allowed within the district if they otherwise meet the standards of this Code. 403. Overlay Districts 403.1 Flood Hazard District (1) Designation of Floodplain Hazard District (a) The floodway-flood boundary and floodway maps prepared for the City by the Federal Insurance administration to be effective February 4, 1981, are hereby adopted. Copies of said maps shall be available in the offices of the Planning Department. (b) A person commits an offense if he makes any change to improved or unimproved real estate (including but not limited to buildings, structures, dredging, filling, grading, paving or excavation) within the floodplain without a development permit (reclamation of land) from the City (see section 106 of this code). (2) General Standards for Flood Hazard Reduction In all areas of special flood hazards the following provisions are required for all new construction and substantial improvements: (a) All new construction or substantial improvements shall be designed (or modified) and adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy; (b) All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage; (c) A11 new construction or substantial improvements shall be constructed with materials resistant to flood damage; (d) All new construction or substantial improvements shall be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding. (e) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system; (f) New and replacement sanitary sewage systems shall be designed to minimize or eliminate in i tration of flood waters into the system and discharge from the systems into flood waters; and, (g) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. (3) Specific Standards In all areas of special flood hazards where base flood elevation data has been provided as set forth in 403.1 (1)(a), 403.1 (8)(h), or 403.1 (1)(4 )(d), the following provisions are required: (a) Residential Construction New construction and substantial improvement of any residential structure shall have the lowest floor elevated to or above the base flood elevation. A registered professional engineer, architect, or land surveyor shall submit a certification to the City prior to receiving a development permit that the standard of this subsection (403.1 (9 )(a)) is satisfied. (including basement), (b) Nonresidential Construction New construction and substantial improvements of any commercial, industrial or other nonresidential structure shall either have the lowest floor (including basement) elevated to or above the base flood level or, together with attendant utility and sanitary facilities, be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall develop and/or review structural design, specifications, and plans for the construction, and shall certify that the design and methods of construction are in accordance with accepted, standards of practice as outlined in this subsection. A record of such certification which includes the specific elevation (in relation to mean sea level) to which such structures are floodproofed shall be maintained by the City as part of the permanent development permit file. (c) Enclosures New construction and substantial improvements, with fully enclosed areas below the lowest floor that are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria: (1) A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided. (2) The bottom of all openings shall be no higher than on foot above grade. (3) Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. Manufactured Homes (1) All manufactured homes to be placed within Zone A, shall be installed using methods and practices which minimize flood damage. For the purpose of this requirement, manufactured homes must be elevated and anchored to resist flotation, collapse, or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to round anchors. This re uirement is in addition to applicable State and local anchoring requirements for resisting wind forces. All manufactured homes shall be in compliance with 403.1 (3)(a). All manufactured homes to be placed or substantially improved within Zones A1-30, AH and AE on the City s FIRM shall be elevated on a permanent foundation suc that the lowest floor of the manufactured home is at or above the base flood elevation; and be securely anchored to an adequately anchored foundation system in accordance with the provisions of section 403.1 (3)(d)(1). (4) A person commits an offense if he places any manufactured home in the regulatory floodway in other than an existing manufactured home park or manufactured home subdivision. (4) Standards for Subdivision Proposals (a) All subdivision proposals including manufactured home parks and subdivisions shall be consistent with the provisions of section 104. (b) The developer of subdivisions including manufactured home arks and subdivisions shall obtain a development permit see section 104 of this code) prior to final platting. (c) Base flood elevation data shall be generated for subdivision proposals and other proposed development including manufactured home parks and subdivisions which is greater than 50 lots or 5 acres, whichever is lesser, if not otherwise ovided u suant to section 403.1 or else here in this Code. (d) All subdivision proposals including manufactured home parks and subdivisions shall have adequate drainage provided to reduce exposure to flood hazards. (e) All subdivision proposals including manufactured home parks and subdivisions shall have public utilities and facilities (sewer, gas, electrical and water systems) located and constructed to minimize or eliminate flood damage. (5) Standards For Areas of Shallow Flooding (A0/AH Zones) Located within the areas of special flood hazard established in section 403.1 (1)(a), are areas designated as shallow flooding. These areas have special flood hazards associated with base flood depths of 1 to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply: (a) All new construction and substantial improvements of residential structures shall have the lowest floor includin' basement elevated above the hi hest ad'acent rade at least as h h as the de h number s.ecified in feet on the cit, FIRM at least two feet if no depth number is specifie (b) All new construction and substantial improvements of nonresidential structures: (1) shall have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the city_s FIRM (at least two feet if no depth number is spejfied), or; (2) together with attendant utility and sanitary facilities be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads of effects of buoyancy. (c) A registered professional engineer or architect shall submit a certification to the City which shall become part of the permanent development permit file that the standards of section 106.3, are satisfied. (d) Within Zones AH or AO the developer shall provide adequate drainage paths around structures on slopes, to guide flood waters around and away from proposed structures. (6) Floodways Floodways are located within areas of special flood hazard established in 403.1 (1)(a). Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles and erosion potential, the following provisions shall apply: (a) Encroachments are prohibited, including fill, new construction, substantial improvements and other development unless certification by a professional registered engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels within the city during the occurrence of the base flood discharge. (b) Where section 403.1 (6)(a) above is satisfied,, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of sections 403.1 (2) and 403.1(3). (7) Designation Of The Floodplain Administrator The City Engineer is hereby appointed the Floodplain Administrator to administer and implement the provisions of this ordinance and other appropriate sections of 44 CFR (National Flood Insurance Program Regulations) pertaining to flood plain management. (8) Duties & Responsibilities Of The Floodplain Administrator Duties and responsibilities of the Floodplain Administrator shall include, but not be limited to, the following: (a) Maintain and hold open for public inspection all records pertaining to the provisions of this section. (b) Review permit applications to determine whether proposed building sites will be reasonably safe from flooding. (c) Review, approve or deny all applications for development permits required by adoption of this section. (d) Review permits for proposed development to assure that all necessary permits have been obtained from those Federal, State or local governmental agencies (including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334) from which prior approval is required. (e) Determine the flood hazard boundary line where interpretation is needed as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). (f) Notify, in riverine situations, adjacent communities and the State Coordinating Agency which is the Texas Water Commission, prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency. (g) Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained. (h) Obtain, review and reasonably utilize any base flood elevation data and floodway data available from a Federal, State or other source, in order to administer the provisions of the section when base flood elevation data has not been provided in accordance with section 403.1 (1)(a). * Re'uire that no 1M be when a • new construction includin fill he Cit subs antial ovemen s or other devel ermitted within Zones Al- e ula o flood a has is demonstrated that the cumulative effect of the o ment when combined with al other an lc' a ed develo en Face elevation of the base o'n h n the communi . 0$ en 0 and AE on not been des nae sha s FIRM unless it ro osed exis in, and the water sur one foot at an • d eve 1_9111_Enrflir---.ocedures A develoser ma a ea has been nation in a n hazard shall be ned in sec there deter ood a IS ea conta a iances shall not be issued within an desisnated floodwa an increase in flood levels dur n• the base flood discharle would result.

Such zones are shown on the Huntsville Municipal Airport Hazard Zoning Map and dated June 10, 1976, which is hereby adopted and made a part of this code. An area located in more than one of the following zones in considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows: (a) Approach Zone The "runway larger than utility with a visibility minimum greater than three - fourths (3/4) mile nonprecision instrument approach zone" called Approach Zone. The inner edge of this approach zone coincides with the width of the primary surface (runway) and is five hundred (500) feet wide. The approach zone expands outward uniformly to a width of three thousand five hundred (3,500) feet at a horizontal distance of ten thousand (10,000) feet from the primary surface, its centerline being the continuation of the centerline of the runway. (b) Transitional zones. These zones are established as the area beneath the transitional surfaces. These surfaces extend outward and upward at ninety- degree angles to the runway centerline, and the runway centerline extends at a slope of seven (7) feet horizontally for each foot vertically from the sides of the primary approach surfaces to where they intersect the horizontal surface. (c) Horizontal zone. The horizontal zone is established by swinging arcs of ten thousand (10,000) feet radii from the center of each end of the primary surface of each runway, and connecting to the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones. (d) Conical zone. The conical zone is hereby established as the area that commences at the periphery of the horizontal zone and extends outward there from a horizontal distance of four thousand (4,000) feet. (2) Airport Zone Height Limitations Except as otherwise provided, no structure or tree shall be erected, altered, allowed to grow or be maintained in any zone within the Airport Hazard District created to a height in excess of the applicable height limit established for such zone. Where an area is covered by more than one height limitation the more restrictive height shall prevail.Such applicable height limitations are: (a) Approach Zone Slopes upward thirty-four (34) feet horizontally for each foot vertically beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of ten thousand (10,000) feet along the extended runway centerline. (b) Transitional Zone Slopes upward and outward seven (7) feet horizontally for each foot vertically beginning at the sides of and at the same elevation as the primary surface and the approach zones, and extending to a height of one hundred fifty (150) feet above the airport elevation (363 feet above mean sea level). Additionally, there are established height limits sloping upward and outward (7) feet horizontally for each foot vertically beginning at the side of and at the same elevation as the approach zones, and extending to where they intersect the horizontal or conical surface. (c) Horizontal Zone One hundred and fifty (150) feet above the airport elevation or a height of five hundred and thirteen (513) feet above mean sea level. (d) Conical Zone Slopes upward and outward twenty (20) feet horizontally for each foot vertically beginning at the periphery of the horizontal zone and at one hundred and fifty (150) feet above the airport elevation and extending to a height of three hundred and fifty (350) feet above the airport elevation. (3) Use Restrictions Notwithstanding any other provisions of this section, no use may be made of land or water within any airport hazard zone established by this Code in such a manner as to create electrical interference with navigational signals or radio communications between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and other, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, or otherwise in any way create a hazard or endanger the landing, takeoff or maneuvering of aircraft intending to use the airport. (4) Nonconforming Uses (a) Regulation Not Retroactive The regulations prescribed by this code shall not be construed to require the removal, lowering or other changes or alterations of any structure or tree not conforming to the regulations as of October 15, 1976. (b) Marking and lighting The owner of any existing nonconforming structure or tree is hereby required to permit the installation, operation and maintenance of such markers and lights as shall be deemed necessary by the City to indicate to the operators of aircraft in the vicinity of the airport, the presence of such airport hazards. Such markers and lights shall be installed, operated and maintained at the expense of the City. (5) Permits (a) Future uses No material change shall be made in the use of the land, and no structure or tree shall be erected, altered, planted or otherwise established in any airport hazard district zone hereby created unless a permit has been applied for and granted by the City. (1) However, a permit for a tree or structure of less than seventy-five (75) feet of vertical height above the ground shall not be required in the horizontal and conical zones or in any approach and transitional zones beyond a horizontal distance of four thousand two hundred (4,200) feet from each end of the runway except when such tree or structure, because of the terrain, land contour or topographic feature, would extend above the height limit prescribed for the respective zone. (2) Each application for a permit shall indicate the purpose for which the permit is desired with sufficient particulars to determine whether the resulting use, structure or tree would conform to the regulations herein prescribed. If such determination is in the affirmative, the permit shall be granted. (b) Existing uses No permit shall be granted that would allow the establishment or creation of an airport hazard or permit a nonconforming use, structure or tree to become a greater hazard to air navigation than it was on October 15, 1976. (c) Hazard marking and lighting Any permit or variance granted may, if such action is deemed advisable to effectuate the purpose of this code and to be reasonable in the circumstances, be so conditioned as to require the owner of the structure or tree in question to permit the City, at its own expense, to install, operate and indicate to pilots the presence of an airport hazard. 404. DESIGNATION OF ANNEXED PROPERTY Territory annexed to the City shall be designated in the management district. 405. Interpretation of District Boundaries The following rules shall be used to determine the precise location of any designated district boundary of the City: (1) Boundaries shown or described as following or approximately following the City Limits shall be construed as following such limits. (2) Boundaries shown or described as following or approximately following streets shall be construed to follow the centerlines of such streets. (3) Boundary lines shown or described as following or approximately following platted lot lines or other property lines as shown on plats filed for record in the office of the County Clerk shall be construed as following such lines. (4) Boundaries shown or described as following or approximately following centerlines of streams, creeks, or other water courses shall be construed as following the channel centerline of such water courses and, in the event of a natural change in the (5) location of such streams, creeks, or other water courses, the boundary line shall be construed as moving with the channel centerline. Boundaries shown or described as separated from and parallel or approximately parallel to, any of the features listed in paragraphs (1) through (4) above shall be construed to be parallel to such features and at such distances as are shown on the map. 406. LAND USE STANDARDS The Table 4-1: Allowable Uses lists those land use categories allowable in each district. Specific locational standards for individual lot types are contained in Chapters 5 and 6 of this Code. (1) Residential Uses Residential uses may include single-family housing, multifamily developments, or mobile home developments, and can accommodate a variety of dwelling unit types. General standards for residential uses are in Section 502. (2) Non-Residential Uses All land uses not classified as residential are considered non- residential in nature. Table 4-1 lists the non-residential land uses according to major use category. Wherever possible, the group descriptions in the Standard Industrial Classification Manual (SIC) (1987) prepared by the Statistical Policy Division for the United States Office of Management and Budget shall be used to determine the classification of primary uses for accomplishing the purposes of this Code. A copy of the SIC manual shall be filed in the office of the Planning Department for inspection during normal business hours.
