Recent rainfall damage report, Documents from previous meetings. STAFF SUMMARY Background: City Council has requested the Building and Standards Commission (BSC) to review the finished floor requirements in relation to Base Flood Elevation (BFE). Presently the City's ordinance requires that finished floor elevation to be at or above BFE. Some cities require an additional 1 to 2 feet above BFE which is known as "freeboard". The advantages and disadvantages of requiring freeboard were discussed jointly between the ZPC and BSC in 2006-2007. Documentation from those meetings has been included for reference. Some of the key concerns were: • The need for fill to elevate structures. • The impact on drainage of surrounding properties. • The possible impact to maximum height requirements for structures. Presently it is 35 feet above Standard Base Level (natural grade). • The hardships that may be created for existing structures that are substantially improved and would be required to meet the higher finished floor elevation. From 2012 — present, 212 new home permits have been issued. 26 of these were built in the floodplain or 12%. 1 • • Chapter 18- BUILDINGS AND DEVELOPMENTU ARTICLE IX. - FLOOD DAMAGE PREVENTION Sec. 18-271. -Statutory authorization,findings of fact, purpose and methods. (a) Statutory authorization. The Legislature of the State of Texas has in ch. 16, subch. I, Texas Water Code, delegated the responsibility of local governmental units to adopt regulations designed to minimize flood losses. Therefore, the city council of the City of West University Place, Texas ("West University Place"), does ordain as follows: (b) Findings of fact. (1) The flood hazard areas of West University Place are subject to periodic inundation, which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety and general welfare. (2) These flood losses are created by the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, floodproofed or otherwise protected from flood damage. (c) 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: (1) Protect human life and health; (2) Minimize expenditure of public money for costly flood control projects; (3) Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (4) Minimize prolonged business interruptions; (5) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; (6) Help maintain a stable tax base by providing for the sound use and development of floodprone areas in such a manner as to minimize future flood blight areas; and (7) Insure that potential buyers are notified that property is in a flood area. (d) Methods of reducing flood losses. In order to accomplish its purposes, this article uses the following methods: (1) Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in flood heights or velocities; (2) Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (3) Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters; (4) Control filling, grading, dredging and other development which may increase flood damage; Page 1 • (5) Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards to other lands. (Ord. No. 1849, § 1(app. A), 7-9-2007) Sec. 18-272. - Definitions. Unless specifically defined below, words or phrases used in this article shall be interpreted to give them the meaning they have in common usage and to give this article its most reasonable application. Alluvial fan flooding means flooding occurring on the surface of an alluvial fan or similar landform which originates at the apex and is characterized by high-velocity flows; active processes of erosion, sediment transport, and deposition; and unpredictable flow paths. Apex means a point on an alluvial fan or similar landform below which the flow path of the major stream that formed the fan becomes unpredictable and alluvial fan flooding can occur. Appurtenant structure means a structure which is on the same parcel of property as the principal structure to be insured and the use of which is incidental to the use of the principal structure. Area of future conditions flood hazard means the land area that would be inundated by the one- percent-annual chance (100-year)flood based on future conditions hydrology. Area of shallow flooding means a designated AO, AH, AR/AO, AR/AH, or VO zone on a community's Flood Insurance Rate Map (FIRM) with a one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow. Area of special flood hazard means the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year. The area may be designated as zone A on the Flood Hazard Boundary Map (FHBM). After detailed rate making has been completed in preparation for publication of the FIRM, zone A usually is refined into Zones A, AO, AH, A1-30, AE, A99, AR, AR/A1-30, AR/AE, AR/AO, AR/AH, AR/A, VO, V1-30, VE or V. Base flood means the flood having a one percent chance of being equaled or exceeded in any given year. Base Flood Elevation (BFE) means elevation shown on the Flood Insurance Rate Map (FIRM) and found in the accompanying Flood Insurance Study(FIS)for zones A, AE, AH, A1-A30, AR, V1-V30, or VE that indicates the water surface elevation resulting from the flood that has a one percent chance of equaling or exceeding that level in any given year- also called the base flood. Basement means any area of the building having its floor subgrade (below ground level) on all sides. Breakaway wall means a wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces, without causing damage to the elevated portion of the building or supporting foundation system. Critical feature means an integral and readily identifiable part of a flood protection system, without which the flood protection provided by the entire system would be compromised. Development means any manmade change to improved and unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials. Elevated building means, for insurance purposes, a nonbasement building, which has its lowest elevated floor, raised above ground level by foundation walls, shear walls, posts, piers, pilings, or columns. Page 2 • • Existing construction means for the purposes of determining rates, structures for which the "start of construction" commenced before the effective date of the FIRM or before January 1, 1975, for FIRMs effective before that date. "Existing construction" may also be referred to as "existing structures." Existing manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the floodplain management regulations adopted by a community. Expansion to an existing manufactured home park or subdivision means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads). Flood or Flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from: (1) The overflow of inland or tidal waters. (2) The unusual and rapid accumulation or runoff of surface waters from any source. 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 (i.e., mudflow) and/or flood-related erosion hazards. Flood Insurance Rate Map (FIRM) means an official map of a community, on which the Federal Emergency Management Agency has delineated both the special flood hazard areas and the risk premium zones applicable to the community. Flood Insurance Study(FIS) see Flood Elevation Study Floodplain or Floodprone area means any land area susceptible to being inundated by water from any source (see definition of flooding). Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage, including but not limited to emergency preparedness plans, flood control works and floodplain management regulations. Floodplain management regulations means zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as a floodplain ordinance, grading ordinance and erosion control ordinance) and other applications of police power. The term describes such state or local regulations, in any combination thereof, which provide standards for the purpose of flood damage prevention and reduction. Flood protection system means those physical structural works for which funds have been authorized, appropriated, and expended and which have been constructed specifically to modify flooding in order to reduce the extent of the area within a community subject to a "special flood hazard" and the extent of the depths of associated flooding. Such a system typically includes hurricane tidal barriers, dams, reservoirs, levees or dikes. These specialized flood-modifying works are those constructed in conformance with sound engineering standards. Floodproofing means any combination of structural and nonstructural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents. Floodway—see Regulatory Floodway. Functionally dependent use means a use, which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, but does not include long-term storage or related manufacturing facilities. Page 3 • • Highest adjacent grade means the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.

By an approved state program as determined by the Secretary of the Interior; or b. Directly by the Secretary of the Interior in states without approved programs. Levee means a manmade 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. 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. Lowest floor means the lowest floor of the lowest enclosed area (including basement). An unfinished or flood-resistant enclosure, usable solely for parking or vehicles, building access or storage in an area other than a basement area is not considered a building's lowest floor; provided that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirement of Section 60.3 of the National Flood Insurance Program regulations. Manufactured home means a structure transportable in one or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when connected to the required utilities. The term "manufactured home" does not include a "recreational vehicle". Manufactured home park or subdivision means a parcel (or contiguous parcels) of land divided into two or more manufactured home lots for rent or sale. Mean sea level means, for purposes of the National Flood Insurance Program, the National Geodetic Vertical Datum (NGVD) of 1929, or other datum, to which base flood elevations shown on a community's flood insurance rate map are referenced. New construction means, for the purpose of determining insurance rates, structures for which the "start of construction" commenced on or after the effective date of an initial FIRM or after December 31, 1974, whichever is later, and includes any subsequent improvements to such structures. For floodplain management purposes, "new construction" means structures for which the "start of construction" commenced on or after the effective date of a floodplain management regulation adopted by a community and includes any subsequent improvements to such structures. New manufactured home park or subdivision means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of floodplain management regulations adopted by a community. Recreational vehicle means a vehicle which is: (1) Built on a single chassis; Page 4 • • (2) 400 square feet or less when measured at the largest horizontal projections; (3) Designed to be self-propelled or permanently towable by a light duty truck; and (4) Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. Regulatory floodway 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. Riverine means relating to, formed by, or resembling a river (including tributaries), stream, brook, etc. Special flood hazard area—see Area of Special Flood Hazard. Start of construction (for other than new construction or substantial improvements under the Coastal Barrier Resources Act (Pub. L. 97-348)), includes substantial improvement 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 of the permit date. 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 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 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 means, for floodplain management purposes, a walled and roofed building, including a gas or liquid 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 its before-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. Substantial improvement 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 "start of construction" of the improvement. This term includes structures which have incurred "substantial damage", regardless of the actual repair work performed. The term does not, however, include either: (1) 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; or (2) Any alteration of a "historic structure", provided that the alteration will not preclude the structure's continued designation as a "historic structure." Variance means a grant of relief by a community from the terms of a floodplain management regulation. (For full requirements see Section 60.6 of the National Flood Insurance Program regulations.) Violation means the failure of a structure or other development to be fully compliant with the community's floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in Section 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5) is presumed to be in violation until such time as that documentation is provided. Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, (or other datum, where specified), of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.

(3) Review, approve or deny all applications for development permits required by adoption of this article. Page 6 • • (4) 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. (5) 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) the floodplain administrator shall make the necessary interpretation. (6) Notify, in riverine situations, adjacent communities and the state coordinating agency which is the Texas Commission on Environmental Quality(or its successor as state coordinating agency, e.g., Texas Water Development Board), prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency. (7) Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained. (8) When base flood elevation data has not been provided in accordance with subsection 18- 273(b), the floodplain administrator shall 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 section 18-275. (9) When a regulatory floodway has not been designated, the floodplain administrator must require that no new construction, substantial improvements, or other development (including fill) shall be permitted within zones A1-30 and AE on the community's FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community. (10) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program regulations, a community may approve certain development in zones A1-30, AE, AH, on the community's FIRM which increases the water surface elevation of the base flood by more than one foot, provided that the community first completes all of the provisions required by Section 65.12. (c) Permit procedures. (1) Application for a floodplain development permit shall be presented to the floodplain administrator on forms furnished by him/her and may include, but not be limited to, plans in duplicate drawn to scale showing the location, dimensions, and elevation of proposed landscape alterations, existing and proposed structures, including the placement of manufactured homes, and the location of the foregoing in relation to areas of special flood hazard. Additionally, the following information is required: a. Elevation (in relation to mean sea level), of the lowest floor (including basement) of all new and substantially improved structures; b. Elevation in relation to mean sea level to which any nonresidential structure shall be flood proofed; c. A certificate from a registered professional engineer or architect that the nonresidential floodproofed structure shall meet the floodproofing criteria of subsection 18-275(b)(2); d. Description of the extent to which any watercourse or natural drainage will be altered or relocated as a result of proposed development; e. Maintain a record of all such information in accordance with subsection 18-274(b)(1); (2) Approval or denial of a floodplain development permit by the flooplain administrator shall be based on all of the provisions of this article and the following relevant factors: a. The danger to life and property due to flooding or erosion damage; Page 7 • • b. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; c. The danger that materials may be swept onto other lands to the injury of others; d. The compatibility of the proposed use with existing and anticipated development; e. The safety of access to the property in times of flood for ordinary and emergency vehicles; f. The costs of providing governmental services during and after flood conditions including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical and water systems; g. The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site; h. The necessity to the facility of a waterfront location, where applicable; i. The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use. (d) Variance procedures. (1) The appeal board, as established by the community, shall hear and render judgment on requests for variances from the requirements of this article. (2) The appeal board shall hear and render judgment on an appeal only 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. (3) Any person or persons aggrieved by the decision of the appeal board may appeal such decision in the courts of competent jurisdiction. (4) The floodplain administrator shall maintain a record of all actions involving an appeal and shall report variances to the Federal Emergency Management Agency upon request. (5) Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this article. (6) 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 level, providing the relevant factors in subsection (c)(2) of this section have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. (7) Upon consideration of the factors noted above and the intent of this article, the appeal board may attach such conditions to the granting of variances as it deems necessary to further the purpose and objectives of this article (subsection 18-271(c)). (8) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (9) 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 necessary to preserve the historic character and design of the structure. (10) Prerequisites for granting variances: a. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. b. Variances shall only be issued upon: (i) Showing a good and sufficient cause; Page 8 • • (ii) A determination that failure to grant the variance would result in exceptional hardship to the applicant; and (iii) A 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. c. Any application to which a variance is granted shall be given written notice that the structure will be permitted to be built with the lowest floor elevation below the base flood elevation, and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. (11) Variances may be issued by a community for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that: a. The criteria outlined in subsections 18-274(d)(1)—(9) are met; and b. The structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety. (Ord. No. 1849, § 1(app. A), 7-9-2007) Sec. 18-275. - Provisions for flood hazard reduction. (a) General standards. In all areas of special flood hazards the following provisions are required for all new construction and substantial improvements: (1) 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; (2) All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage; (3) All new construction or substantial improvements shall be constructed with materials resistant to flood damage; (4) 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; (5) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system; (6) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the system and discharge from the systems into floodwaters; and, (7) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

(c) Standards for subdivision proposals. (1) All subdivision proposals including the placement of manufactured home parks and subdivisions shall be consistent with subsections 18-271(b), (c), and (d) of this article. (2) All proposals for the development of subdivisions including the placement of manufactured home parks and subdivisions shall meet floodplain development permit requirements of subsection 18-273(c); subsection 18-274(c); and the provisions of section 18-275 of this article. (3) Base flood elevation data shall be generated for subdivision proposals and other proposed development including the placement of manufactured home parks and subdivisions which is greater than 50 lots or five acres, whichever is lesser, if not otherwise provided pursuant to subsection 18-273(b)or subsection 18-274(b)(8) of this article. (4) All subdivision proposals including the placement of manufactured home parks and subdivisions shall have adequate drainage provided to reduce exposure to flood hazards. (5) All subdivision proposals including the placement of manufactured home parks and subdivisions shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage. (d) Standards for areas of shallow flooding (AO/AH zones). Located within the areas of special flood hazard established in subsection 18-273(b), are areas designated as shallow flooding. These areas have special flood hazards associated with flood depths of one to three feet where a clearly defined channel does not exist, 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: (1) All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated to or above the base flood elevation or the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified). (2) All new construction and substantial improvements of nonresidential structures: a. Have the lowest floor (including basement) elevated to or above the base flood elevation or the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified), or b. Together with attendant utility and sanitary facilities be designed so that below the base specified flood depth in an AO zone, or below the base flood elevation in an AH zone, 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. (3) A registered professional engineer or architect shall submit a certification to the floodplain administrator that the standards of this section, as proposed in subsection 18-274(c), are satisfied. Page 11 • S (4) Require within zones AH or AO adequate drainage paths around structures on slopes, to guide floodwaters around and away from proposed structures. (e) Floodways. Located within areas of special flood hazard established in subsection 18-273(b), 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 shall apply: (1) Encroachments are prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge. (2) If subsection 18-275(e)(1), above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of section 18- 275. (3) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program Regulation, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first completes all of the provisions required by Section 65.12. (f) Severability. If any section, clause, sentence, or phrase of this article is held to be invalid or unconstitutional by any court of competent jurisdiction, then said holding shall in no way affect the validity of the remaining portions of this article. (g) Penalties for noncompliance. No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this article and other applicable regulations. Violation of the provisions of this article by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor. Any person who violates this court order or fails to comply with any of its requirements shall upon conviction thereof be fined not more than allowed by law or imprisoned for not more than allowed by law, or both, for each violation, and in addition shall pay all costs and Y P Y expenses involved in the case. Nothing herein contained shall prevent West University Place from taking such other lawful action as is necessary to prevent or remedy any violation. (Ord.

A condition of participation in the NFIP is adoption and enforcement of a flood damage prevention and protection ordinance and adoption of the most current Flood Insurance Rate Map (FIRM). As a result of tropical storm Allison, the Harris County Flood Control District (HCFCD) and the Federal Emergency Management Agency (FEMA) partnered to create the Tropical Storm Allison Recovery Project(TSARP). One of the primary goals of the project was to re-map all of the FIRM's for Harris County, including the FIRM panels for West University Place. Preliminary maps were published in September 2004. According the HCFCD, 250 appeals and protests were received by FEMA during the 90-day appeal and protest period. Several complicated appeals in the Spring and Cypress Creek watersheds caused delays in the map implementation process, but FEMA is currently finalizing the maps and will be sending out the Letter of Final Determination to the participating communities within the next thirty days. This means that the participating communities will have six (6) months to change their flood prevention and protection ordinances to reflect the new maps. According to correspondence received from the Tropical Storm Allison Recovery Project group, anticipated effective date of the new maps is January 2007. Once the maps are published, • flood insurance rates and requirements will be determined based upon the new FIRM's. The proposed new FIRM's will increase the amount of property located in the Special Flood Hazard Area(SFHA) substantially. Under the current FIRM, only a relatively small nine-block area (east of Poor Farm Ditch,between Mercer and Rutgers and Mercer and Vanderbilt) is located in the SFHA, or 100-year floodplain. The preliminary FIRM's have expanded the SFHA five blocks north to University Boulevard and east to Fordham. Also included is a block wide strip from Riley north to Amherst, between College and Auden. The majority of the rest of the City is located in either the Shaded X or X Zones. The previous FIRM map only showed one cross-section where the base flood elevation was delineated at 49'. The proposed new maps are more developed with seven cross- sections, four where base flood elevations are delineated ranging from 47' to 50'. The FEMA and State regulations require that all new construction and substantial improvements to existing construction be built so that the finished floor elevation of the structure meet or exceed the mapped base flood elevation. Several of the surrounding communities have enacted "freeboard"requirements (higher regulatory ry standar d standards) that require structures to meet or exceed the base flood elevation lus increments in inches between one and two feet. The BSC discussed the implications of this type of regulation for West University Place during several meetings and workshops over the past two years. The concerns they had in enacting this type of requirement centered around the need for fill to elevate structures and the impacts on drainage of surrounding properties, the possible impact to the maximum height requirements for structures, and the hardships that may be created for �1J1 atiath YylutLikq rannall) • existing structures, especially the `old stock housing" that residents may want to structurally alter, in meeting additional finished floor elevation requirements. At the January 2006 meeting of the BSC, the members voted to recommend adoption of the new FIRM's when published and adoption of the minimum floodplain regulations with no higher regulatory standards until such time that a workshop with City Council could be arranged to discuss these issues. On May 4, 2006, a joint workshop was held with City Council and members of the BSC and ZPC to present an overview of these issues and obtain direction from City Council in order to proceed. The joint workshop on June 29 is to fully orient the members of both commissions as to the areas of responsibility of each group as they pertain to flood prevention issues. • • 4 Ottaditfitaillet /0 -7//3/u Definitions • SUBSTANTIAL DAMAGE -means 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. SUBSTANTIAL IMPROVEMENT -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 "start of construction" of the improvement. This term includes structures that have incurred "substantial damage", regardless of the actual repair work performed. The term does not, however, include either. (1) 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 or (2) Any alteration of a "historic structure", provided that the alteration will not preclude the structure's continued designation as a "historic structure." • NEW CONSTRUCTION -means, for the purpose of determining insurance rates, structures for which the "start of construction" commenced on or after the effective date of an initial FIRM or after December 31, 1974, whichever is later, and includes any subsequent improvements to such structures. For floodplain management purposes, "new construction" means structures for which the "start of construction" commenced on or after the effective date of a floodplain management regulation adopted by a community and includes any subsequent improvements to such structures. LOWEST FLOOR -means the lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable solely for parking or vehicles, building access or storage in an area other than a basement area is not considered a building's lowest floor; provided that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirement of Section 60.3 of the National Flood Insurance Program regulations. DEVELOPMENT -means any man-made change_ta_improved_anrf • unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials. I -7/01N0 atiojj-iy9 • Issues for Discussion at Joint ZPC / BSC Workshop June 29,2006 The BSC will address the freeboard issue. The BSC will make a recommendation of how much additional freeboard the city should require of new construction above the BFE. The finished floor of houses built in the 100-year flood plain must be built at the BFE elevation for that particular property, as determined with the federal FIRM maps and the federal calculation methods. This BFE must be attached to the plans for the house. As a strawman proposal, the chair proposes no additional freeboard. Some pros on this include: • Additional freeboard above the BFE is at the builder or owner's discretion. • The BFE will change over time as the HCFCD alters the BFE through drainage control projects. These projects will more than likely lower the BFE from time to time, making additional freeboard requirements moot, especially for houses built to earlier BFE levels • The finished floor height at the BFE will allow minimize mitigate houses from flooding • due to a 100 year event. • The effect on increased roof heights will be minimal. Some cons are: Some new houses could possibly flood, The homeowner would not be eligible for potential lower flood insurance rates Finally, the CBO could suggest to homebuilders and others that they make a personal decision on what to do with respect to freeboard above the BFE on an individual case basis. The chair asks for an open discussion of this strawman on freeboard. • ir 71/31D(D ,p , „ riblutro,L • The third issue deals with under-house drainage and net fill. The intent of the discussion on under-house drainage is to allow the soil beneath houses built with crawl spaces to dry quickly. This in turn will minimize moisture related decay of construction materials, prevent breeding places for mosquitoes or termites, and to meet certain codes. This is a BSC area issue. As a strawman position, the chair proposes that the current IBC codes be followed on this type of construction. The code requires under-house drainage by gravity or by artificial lift. It also requires under-house ventilation to dry out this area after raining or flooding. Some pros are: The house will last longer without material decay issues to the future homeowner, and Water will not pool for insect problems Some cons are: This will be an additional cost to constructing a house. The chair would like to open this issue for discussion. • The second half of the issue of lot drainage concerns net fill. This issue is believed to be a ZPC issue. The ZPC will discuss the meaning of net fill, and the issues of driveway and garage elevations, and additions of construction related clays for foundations. 111 I • t 7/ Jo a f7PC 1/ • • The fourth issue concerns existing housing. Houses built prior to the enactment of the FIRM maps will be subject to the associated FEMA mandated rules and codes when "substantial" modifications / repairs "alterations" and additions are made to houses with finished floors are below the BFE. The second half of this existing housing issue is the repair of flood damages. Repair costs of these existing houses for flood damages is a cumulative process. The CBO is required to track these costs by each flood-damaged house. Once the cumulative damages exceed a certain percent value of the structure, certain actions are triggered. The CBO has been asked to draft a summary of definitions and requirements that must be met by those modifying an existing house that has a finished floor below the BFE. The determination of the value of such an existing house is a major issue to determine the compliance to this par of the FEMA mandated ordinances. The CBO is requested to propose several valuation methods that will be allowed by the city to determine compliance with the FEA definitions, the basis for applying the definition of substantial, and the cumulative compliance to these rules. The BSC will take this as a strawman position and discuss the CBO's position. The chair would like to open this issue for discussion. • • 710110,d ifTrny- -/77.Li7Lure>,& • The chairs of the ZPC and the BSC identified several ancillary issues. These issues more than likely fall into the jurisdiction of the BSC, however, a joint discussion is desired by both the ZPC and the BSC. The first issue is flooding caused to houses by drivers driving through flooded streets creating a wake. The BSC chair proposes a strawman proposal that the BSC works with the Police Department to create a draft ordinance proposal allowing WUP emergency officials to issue stop individuals driving through flooded streets over certain speeds, or no driving including the issuance of citations. In essence to create a no wake zone during times of flooded streets. The second part driving through flooded streets is giving West University officials (including Police, Fire Department and Public Works) the authority to temporarily block certain streets during flooded conditions. The BSC will discuss this option workshop session with the police staff. Blocked storm sewers have been an identified a source of street flooding in the city. The BSC will study and recommend ordinance language of a preventative nature that formally prohibits lawn services from blowing or dumping leaves, etc. into the West U • storm sewer system. The ordinance will also formally prohibit construction workers and contractors from allowing dirt and mud from construction sites to remain on the streets that can then enter the storm drains due to rainwater runoff. The CBO will discuss this issue with her staff and propose suggested ordinance language to the BSC. The chairs would like to open these two issues for discussion. • ►r, -7/4fr),(6, 71, • Flood Protection and Prevention Issues West University Place Building Height Should the maximum building height in West U be allowed to rise or float with the base flood elevation(BFE) defined by FEMA plus any"freeboard" decided upon by City Council? The zoning ordinance limits the height of buildings in West University Place to a maximum of 35 feet, with lower limits on some structures (Table 7-4b). Height is measured from the standard base level of a site to the highest point of the structure. The standard base level is essentially the elevation of the building site(above sea level) prior to any filling or site preparation. The standard base level is independent of the BFE. Concerns to be considered range from aesthetics and fairness to possible future changes in the BFE resulting from subsidence, on the one hand, to improved drainage on the other. Site Grade-Raising and Drainage What, if any, changes to building site drainage rules should]d be made? • In general, the city code (Sec. 18-56) requires builders to provide for adequate drainage. The rules are intended to ensure proper drainage of the building site itself, to prevent creation of drainage problems on neighboring sites and to avoid interference with natural flow patterns across property lines. A drainage plan must be filed with the building official before issuance of a building permit. New, higher base flood elevations will probably lead to more dramatic grade raising and greater use of pier-and-beam foundations to keep ground-floor levels above the BFE. Updated provisions to protect neighbors and to ensure necessary drainage under raised foundations may be needed. . • Building and Standards Commission/Zoning and Planning Commission City of West University Place, Texas 3800 University Boulevard West University Place, Texas 77005 March 1, 2007 Honorable Mayor & Members of the City Council City of West University Place 3800 University Boulevard West University Place, Texas 77005-2830 Subject: Report on a directive by City Council to study the zoning and building development regulations of the City of West University Place, Texas ("City") relating to FLOODPLAIN REGULATIONS. To the Honorable Mayor & Members of City Council: The Building & Standards Commission (BSC) and the Zoning & Planning Commission (ZPC) of the City submits this report on the subject proposal for the assistance of the Council as well as other interested persons. Scope of Proposal. City Council directed the members of the BSC and the ZPC to review and study the floodplain regulations and the preliminary revised floodplain maps and accompanying flood insurance study and make recommendations to City Council concerning possible amendments to the flood protection and prevention regulations of the City. The BSC and ZPC met jointly to discuss the preliminary revised floodplain maps (FIRM'S) and the implications of adopting regulations to implement and enforce the FIRM's upon receipt of the final determination letter from the Federal Emergency Management Agency (FEMA) and notification of the effective date of the maps. To participate in the National Flood Insurance Program (NFIP), a community must agree to manage development in its most flood-prone areas. A community must agree to adopt and enforce floodplain management measures that comply with the NFIP's requirements. Local floodplain administrators are responsible for ensuring that those engaged in development activities within the community abide by local floodplain management regulations. The recent revisions to the floodplain maps necessitate the adoption of the latest floodplain maps and accompanying study, as well as possible amendments to the current zoning and building development regulations. The commissions identified several issues resulting from the workshop discussions and agreed to divide the issues between the respective bodies for further discussion and subsequent recommendations to City Council. The identified issues are as follows: CORE ISSUES 1. Should the City of West University Place adopt a"freeboard" requirement (higher regulatory base flood elevation) for all structures located within the special flood hazard areas? 2. Should the maximum building height directly correspond with any higher regulatory"freeboard" requirements? 3. If a freeboard requirement is adopted, what changes to the building site drainage regulations should be made? Should net fill on a building site be limited? • • If structures are elevated (such as in crawl space construction) should stricter provisions for crawl space drainage be considered? 4. Existing structures not currently located in a special flood hazard area will be located in such an area upon the effective date of the new maps. The existing elevations of the structures may hinder the issuance of permits for improvements in the future. What criteria will be used to determine if a structure can be improved, or in some cases repaired, if located in a special flood hazard area? ANCILLARY ISSUES 5. Other issues identified by the commissions included flooding caused by vehicular traffic through flooded streets causing a"wake" effect, thereby causing wave action pushing water into structures; blocked or restricted storm sewers and storm sewer drains from blowing and/or dumping leaves, grass clippings, etc. into the storm drains. Recommendations: 1. Should the City of West University Place adopt a"freeboard" requirement (higher regulatory base flood elevation) for all structures located within the special flood hazard areas? Based on plans pulled from the records, new structures are being built at or above the new base flood elevations currently shown on the existing and proposed maps. The base flood elevations did not change for currently mapped floodplain areas, but the geographical location of the floodplain has increased. Records indicate that many properties are already at or above base flood elevation prior to demolition of existing structures and construction of new structures. Higher regulatory standards would impact structures in regards to height restrictions more often than provide additional protection to those structures. The major drainage work taking place and planned for the future on Brae's Bayou, College Avenue and Poor Farm Ditch is expected to help in alleviating flooding conditions and lower base flood elevations will likely result. Recommendation: The commission members voted to recommend no increase in base flood elevation. 2. Should the maximum building height directly correspond with any higher regulatory "freeboard" requirements? Based on plans submitted and input from building industry members of both commissions, if any higher regulatory standard is imposed,the effect on the overall height restriction of 35' will be negligible. Plate heights and roof slopes can be adjusted to accommodate increased floor height requirements. Recommendation: The commission members voted to recommend no change in the maximum building heights. 3. If a"freeboard" requirement is adopted, what changes to the building site drainage regulations should be made? Should net fill on a building site be limited? If structures are elevated (such as in crawl space construction) should stricter provisions for crawl space drainage be considered? The commissioners believe that the question of fill is regulated by the establishment of a standard base elevation prior to any grade raising or construction activity as required in the current drainage regulations. Since grade raising affects the finished height of a structure and all drainage must be contained within the property lines of the building site, a limit on net fill is not necessary. Additionally, recently adopted foundation regulations encourage the installation of crawl space and void box with deep footing (pier) systems, both which contribute to limiting the amount of fill brought to a building site. The Federal Emergency Management Agency has published a technical • • bulletin to use as a guide for the proper installation of drainage under crawl spaces. The International Building Code and International Residential Code cite crawl space drainage and moisture protective requirements as well. Recommendation: The commissions recommend no changes to the building site drainage, net fill, or crawl space drainage requirements are needed. 4. Existing structures not currently located in a special flood hazard area will be located in such an area upon the effective date of the new maps. The existing elevations of the structures may hinder the issuance of permits for improvements in the future. What criteria will be used to determine if a structure can be improved, or in some cases repaired, if located in a special flood hazard area? As a condition of participating in the National Flood Insurance Program, which makes flood insurance available to the residents of West University Place, the city must adopt and enforce the minimum FEMA and state regulations for floodplain management. Part of those regulations is rules establishing minimum standards for new construction in special flood hazard areas (100-year floodplain). These standards also apply to structures in a 100-year floodplain that are substantially improved or substantially damaged. Substantial improvement or damage is defined as "repair, reconstruction, or improvement of a structure, where the cost of said improvement equals or exceeds 50% of the market value of the structure either before the improvement started or before the damage occurred." In order to obtain a permit for an improvement to a structure, the applicant must submit data reflecting the market value of the structure before the improvement or damage commenced. Due to the inverse situation of some properties in West University Place where the property values outweigh the improvement values, structures might be required to come into compliance based on relatively minor improvements or repairs. Some repairs (those required by the enforcement authority for life, safety, or health reasons) are excluded from the definition of substantial improvement. Recommendation: The commission recommends for the purpose of determining the value of the structure before being improved or repaired, the Harris County Appraisal District's assessed value for the structure be used. If the applicant wishes to contest this value an independent certified appraisal may be submitted. Upon review and concurrence by the Floodplain Administrator, this appraised value for the structure may be used for determining if the improvement or repair is substantial. ANCILLARY ISSUES The commissions also discussed ancillary issues determined to be beyond the extent of their authority, and submit to City Council for consideration and possible future action. 1. A"no-wake" zone, which would limit the speed of vehicles through flooded streets. 2. Regulations controlling lawn care and landscaping materials from deposit into the storm sewers.

Matters related to a Recreation Specialist Position including approval to fill the position. Parks and Recreation Director Tim O'Connor reported that during the 2007 Budget Process, staff requested a full-time Recreation Specialist position. Council approved the position to be filled July 1, 2007, contingent upon City Council approval prior to the position being posted/filled. Reasoning for the position not being approved for the full year involved waiting for the outcome of the November 2006 Bond Election, since several Council Members felt that the scope of that 3 • • City Council Regular and Special Session,June 25,2007 position might change, depending upon the Bond Election results. The primary justification for the position involves the assuming of Community Building front-line duties, allowing for the Administrative Manager, upgraded from Administrative Assistant on January 1, 2007, to effectively facilitate the additional duties identified in that job description. A motion was made by Council Member Fry, seconded by Council Member Cohen, to authorize the City Manager to allow staff to proceed with filling the position of Recreation Specialist.

Salvage and Demolition. Matters related to salvage and demolition including Ordinance No. 1848. Mayor Kelly read the caption of Ordinance No. 1848 as follows: An ordinance relating to salvage and demolition; amending the code of ordinances of the City of West University Place, Texas; and containing findings and provisions relating to the subject Copies of Ordinance No. 1848, in the form proposed for adoption, were available in the Council Chambers. Building Official Sean Landis reported that Ordinance No. 1848 reflects clarification of Sections 18-1 and 18-65 of the Code of Ordinances, specifically by adding the definition of"demolish" and "demolition" and a provision to further delineate the difference in salvage and demolition. These amendments were primarily written to control the amount of salvage occurring in structures slated to be demolished. Currently, the ordinance requires a permit for the demolition of any structure. The permittee is required to notify the Building Official when the work begins and complete the work within 10 days. A permit is valid for up to 60 days. The amendments will provide an avenue for removal or"salvage" of interior non-structural elements provided no external changes occur. This amendment is intended as an additional tool to keep exterior structural elements from being removed, thereby resulting in possible open and vacant, unsecured structures, which can become an attractive nuisance. A motion was made by Council Member Cohen, seconded by Council Member Talianchich, to adopt Ordinance 1848 regulating Savage and Demolition on first reading. 4 • • City Council Regular and Special Session,June 25,2007 A vote was taken on the motion with the following result: Voting Aye: Mayor Kelly, Council Members Fry, Cohen, Guffey and Talianchich Voting Nay: None Absent: None The motion passed 5-0. Flood Damage Prevention and Floodplain Regulations. Matters related to flood damage prevention and floodplain regulations including Ordinance No. 1849. Mayor Kelly read the caption of Ordinance No. 1849 as follows: An ordinance relating to flood damage prevention and floodplain regulations; amending the code of ordinances of the City of West University Place, Texas; and containing findings and provisions relating to the subject. Copies of Ordinance No. 1849, in the form proposed for adoption, were available in the Council Chambers. Mr. Landis reported that the City of West University Place entered the National Flood Insurance Program (NFIP) in 1978. A condition of participation in the NFIP is adoption of a flood damage prevention and protection ordinance and adoption of the most current Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS). As a result of tropical storm Allison, revising and remapping all of the FIRMs for Harris County, including West University Place, was accomplished. Preliminary maps were published in September 2004 and the final maps were published June 18, 2007. The revised FIRMs will increase the amount of property located in the Special Flood Hazard Area(SFHA). The SFHA includes most of the properties located south of University Boulevard between Poor Farm Ditch and Kirby Road. Additional SFHA includes a block wide strip from Riley north to Amherst, between College and Auden. The BSC and ZPC have discussed the possible ramifications of the expanded floodplain during several meetings and workshops over the past three years. City Council directed the BSC and ZPC to review and study the floodplain regulations and the revised floodplain maps and insurance study and make recommendations for possible amendments to the flood protection and prevention regulations of the City. Ordinance 1849 contains amendments as recommended by the commissions. It provides for adoption of the minimum state and federal floodplain regulations, adopts the revised FIRM's and FIS, and amends the International Residential Code, 2003 edition, to reflect the map revision date. A motion was made by Council Member Cohen, seconded by Council Member Fry,to approve Ordinance 1849 on first reading. 5 • • City Council Regular and Special Session,June 25,2007 A vote was taken on the motion with the following result: Voting Aye: Mayor Kelly, Council Members Fry, Cohen, Guffey and Talianchich Voting Nay: None Absent: None The motion passed 5-0.

STATUTORY AUTHORIZATION The Legislature of the State of Texas has in Chapter 16, Subchapter I, Texas Water Code, delegated the responsibility of local governmental units to adopt regulations designed to minimize flood losses. Therefore, the City Council of the City of West University Place, Texas ("West University Place"), does ordain as follows: SECTION B. FINDINGS OF FACT (1) The flood hazard areas of West University Place are subject to periodic inundation, which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety and general welfare. (2) These flood losses are created by the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, floodproofed or otherwise protected from flood damage. 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) Protect human life and health; (2) Minimize expenditure of public money for costly flood control projects; (3) Minimize the need for rescue and relief efforts associated withflooding and generally undertaken at the expense of the general public; • • (4) Minimize prolonged business interruptions; (5) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; (6) Help maintain a stable tax base by providing for the sound use anddevelopment of flood-prone areas in such a manner as to minimize future flood blight areas; and (7) Insure that potential buyers are notified that property is in a flood area. SECTION D. METHODS OF REDUCING FLOOD LOSSES In order to accomplish its purposes, this ordinance uses the following methods: (1) Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in flood heights or velocities; (2) Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (3) Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; (4) Control filling, grading, dredging and other development which may increase flood damage; (5) Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands. ARTICLE 2 DEFINITIONS Unless specifically defined below, words or phrases used in this ordinance shall be interpreted to give them the meaning they have in common usage and to give this ordinance its most reasonable application. • • ALLUVIAL FAN FLOODING - means flooding occurring on the surface of an alluvial fan or similar landform which originates at the apex and is characterized by high-velocity flows; active processes of erosion, sediment transport, and deposition; and unpredictable flow paths.

Texas and Incorporated Areas," dated June 18, 2007 (revision date), with the most effective Flood Insurance Rate Maps and/or Flood Boundary-Floodway Maps (FIRM and/or FBFM) dated June 18, 2007 (map revised date). SECTION C. ESTABLISHMENT OF DEVELOPMENT PERMIT A Floodplain Development Permit shall be required to ensure conformance with the provisions of this ordinance. SECTION D. COMPLIANCE No structure or land shall hereafter be located, altered, or have its use changed 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 easements, covenants, or deed restrictions. However, where this ordinance and another ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail. SECTION F. INTERPRETATION In the interpretation and application of this ordinance, all provisions shall be; (1) considered as minimum requirements; (2) liberally construed in favor of the governing body; and (3) deemed neither to limit nor repeal any other powers granted under State statutes. SECTION G. WARNING AND DISCLAIMER OR LIABILITY The degree of flood protection required by this ordinance is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. On rare occasions greater floods can and will occur and flood heights may be increased by man-made or natural causes. This ordinance 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 ordinance shall not create liability on the part of the community or any official or employee thereof for any flood damages that result from reliance on this ordinance or any administrative decision lawfully made hereunder. ARTICLE 4 ADMINISTRATION SECTION A. DESIGNATION OF THE FLOODPLAIN ADMINISTRATOR The Building Official is hereby appointed the Floodplain Administrator to administer and implement the provisions of this ordinance and other appropriate sections of 44 CFR (Emergency Management and Assistance - National Flood Insurance Program Regulations) pertaining to floodplain management.

(4) 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. (5) 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) the Floodplain Administrator shall make the necessary interpretation. (6) Notify, in riverine situations, adjacent communities and the State Coordinating Agency which is the Texas Commission on Environmental Quality (or its successor as State Coordinating Agency, e.g., Texas Water Development Board), prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency. (7) Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained. (8) When base flood elevation data has not been provided in accordance with Article 3, Section B, the Floodplain Administrator shall 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 Article 5. (9) When a regulatory floodway has not been designated, the Floodplain Administrator must require that no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A1-30 and AE on the community's FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community. • • (10) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program regulations, a community may approve certain development in Zones A1-30, AE, AH, on the community's FIRM which increases the water surface elevation of the base flood by more than 1 foot, provided that the community first completes all of the provisions required by Section 65.12. SECTION C. PERMIT PROCEDURES (1) Application for a Floodplain Development Permit shall be presented to the Floodplain Administrator on forms furnished by him/her and may include, but not be limited to, plans in duplicate drawn to scale showing the location, dimensions, and elevation of proposed landscape alterations, existing and proposed structures, including the placement of manufactured homes, and the location of the foregoing in relation to areas of special flood hazard. Additionally, the following information is required: (a) Elevation (in relation to mean sea level), of the lowest floor (including basement) of all new and substantially improved structures; (b) Elevation in relation to mean sea level to which any nonresidential structure shall be floodproofed; (c) A certificate from a registered professional engineer or architect that the nonresidential floodproofed structure shall meet the floodproofing criteria of Article 5, Section B (2); (d) Description of the extent to which any watercourse or natural drainage will be altered or relocated as a result of proposed development; (e) Maintain a record of all such information in accordance with Article 4, Section (B)(1); (2) Approval or denial of a Floodplain Development Permit by the Flooplain Administrator shall be based on all of the provisions of this ordinance and the following relevant factors: (a) The danger to life and property due to flooding or erosion damage; (b) The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; (c) The danger that materials may be swept onto other lands to the injury of others; • • (d) The compatibility of the proposed use with existing and anticipated development; (e) The safety of access to the property in times of flood for ordinary and emergency vehicles; (f) The costs of providing governmental services during and after flood conditions including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical and water systems; (g) The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site; (h) The necessity to the facility of a waterfront location, where applicable; (i) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use. SECTION D. VARIANCE PROCEDURES (1) The Appeal Board, as established by the community, shall hear and render judgment on requests for variances from the requirements of this ordinance. (2) The Appeal Board shall hear and render judgment on an appeal only 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 ordinance. (3) Any person or persons aggrieved by the decision of the Appeal Board may appeal such decision in the courts of competent jurisdiction. (4) The Floodplain Administrator shall maintain a record of all actions involving an appeal and shall report variances to the Federal Emergency Management Agency upon request. (5) Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this ordinance. (6) Variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base • • flood level, providing the relevant factors in Section C (2) of this Article have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases. (7) Upon consideration of the factors noted above and the intent of this ordinance, the Appeal Board may attach such conditions to the granting of variances as it deems necessary to further the purpose and objectives of this ordinance (Article 1, Section C). (8) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (9) 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 necessary to preserve the historic character and design of the structure. [10) Prerequisites for granting variances: (a) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (b) Variances shall only be issued upon: (i) showing a good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship to the applicant, and (iii) a 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. (c) Any application to which a variance is granted shall be given written notice that the structure will be permitted to be built with the lowest floor elevation below the base flood elevation, and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. (11) Variances may be issued by a community for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that (i) the criteria outlined in Article 4, Section D (1)-(9) are met, and (ii) the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety. • • ARTICLE 5 PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS In all areas of special flood hazards the following provisions are required for all new construction and substantial improvements: (1) 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; (2) All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage; (3) All new construction or substantial improvements shall be constructed with materials resistant to flood damage; (4) 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; (5) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system; (6) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharge from the systems into flood waters; and, (7) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. SECTION B. SPECIFIC STANDARDS-(AE Zones) In all areas of special flood hazards where base flood elevation data has been provided as set forth in (i) Article 3, Section B, (ii) Article 4, Section B (8), or (iii) Article 5, Section C (3), the following provisions are required: (1) Residential Construction - new construction and substantial improvement of any residential structure shall have the lowest floor (including basement), elevated to or above the base flood elevation. A registered professional engineer, architect, or land surveyor shall submit a certification to • • the Floodplain Administrator that the standard of this subsection as proposed in Article 4, Section C (1) a., is satisfied. (2) 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 Floodplain Administrator. (3) Enclosures - new construction and substantial improvements, with fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement and which 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: (a) A minimum of two openings on separate walls having a total net area of not less than 1 square inch for every square foot of enclosed area subject to flooding shall be provided. (b) The bottom of all openings shall be no higher than 1 foot above grade. (c) Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. (4) Manufactured Homes - (a) Require that all manufactured homes to be placed within Zone A on a community's FHBM or FIRM shall be installed using methods and practices which minimize flood damage. For the purposes 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 ground anchors. This • • requirement is in addition to applicable State and local anchoring requirements for resisting wind forces. (b) Require that manufactured homes that are placed or substantially improved within Zones Al-30, AH, and AE on the community's FIRM on sites (i) outside of a manufactured home park or subdivision, (ii) in a new manufactured home park or subdivision, (iii) in an expansion to an existing manufactured home park or subdivision, or (iv) in an existing manufactured home park or subdivision on which a manufactured home has incurred "substantial damage" as a result of a flood, be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated to or above the base flood elevation and be securely anchored to an adequately anchored foundation system to resist flotation, collapse, and lateral movement. (c) Require that manufactured homes be placed or substantially improved on sites in an existing manufactured home park or subdivision with Zones Al-30, AH and AE on the community's FIRM that are not subject to the provisions of paragraph (4) of this section be elevated so that either: (i) the lowest floor of the manufactured home is at or above the base flood elevation, or (ii) the manufactured home chassis is supported by reinforced piers or other foundation elements of at least equivalent strength that are no less than 36 inches in height above grade and be securely anchored to an adequately anchored foundation system to resist flotation, collapse, and lateral movement. (5) Recreational Vehicles - Require that recreational vehicles placed on sites within Zones A1-30, AH, and AE on the community's FIRM either (i) be on the site for fewer than 180 consecutive days, or (ii) be fully licensed and ready for highway use, or (iii) meet the permit requirements of Article 4, Section C (1), and the elevation and anchoring requirements for "manufactured homes" in paragraph (4) of this section. A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices, and has no permanently attached additions. SECTION C. STANDARDS FOR SUBDIVISION PROPOSALS (1) All subdivision proposals including the placement of manufactured home parks and subdivisions shall be consistent with Article 1, Sections B, C, and D of this ordinance. (2) All proposals for the development of subdivisions including the placement of manufactured home parks and subdivisions shall meet Floodplain Development Permit requirements of Article 3, Section C; Article 4, Section C; and the provisions of Article 5 of this ordinance. (3) Base flood elevation data shall be generated for subdivision proposals and other proposed development including the placement of manufactured home parks and subdivisions which is greater than 50 lots or 5 acres, whichever is lesser, if not otherwise provided pursuant to Article 3, Section B or Article 4, Section B (8) of this ordinance. (4) All subdivision proposals including the placement of manufactured home parks and subdivisions shall have adequate drainage provided to reduce exposure to flood hazards. (5) All subdivision proposals including the placement of manufactured home parks and subdivisions shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage. SECTION D. STANDARDS FOR AREAS OF SHALLOW FLOODING (AO/AH ZONES) Located within the areas of special flood hazard established in Article 3, Section B, are areas designated as shallow flooding. These areas have special flood hazards associated with flood depths of 1 to 3 feet where a clearly defined channel does not exist, 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: (1) All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated to or above the base flood elevation or the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least 2 feet if no depth number is specified). (2) All new construction and substantial improvements of non-residential structures; (a) have the lowest floor (including basement) elevated to or above the base flood elevation or the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least 2 feet if no depth number is specified), or (b) together with attendant utility and sanitary facilities be designed so that below the base specified flood depth in an AO Zone, or below the Base Flood Elevation in an AH Zone, 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. (3) A registered professional engineer or architect shall submit a certification to the Floodplain Administrator that the standards of this Section, as proposed in Article 4, Section C are satisfied. (4) Require within Zones AH or AO adequate drainage paths around structures on slopes, to guide flood waters around and away from proposed structures. SECTION E. FLOODWAYS Floodways - located within areas of special flood hazard established in Article 3, Section B, are areas designated as floodways. 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: (1) Encroachments are prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge. (2) If Article 5, Section E (1) above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Article 5. (3) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Program Regulations, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first completes all of the provisions required by Section 65.12. SECTION F. SEVERABILITY If any section, clause, sentence, or phrase of this Ordinance is held to be invalid or unconstitutional by any court of competent jurisdiction, then said holding shall in no way affect the validity of the remaining portions of this Ordinance. SECTION G. PENALTIES FOR NON COMPLIANCE No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this ordinance • and other applicable regulations. Violation of the provisions of this ordinance by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor. Any person who violates this court order or fails to comply with any of its requirements shall upon conviction thereof be fined not more than allowed by law or imprisoned for not more than allowed by law, or both, for each violation, and in addition shall pay all costs and expenses involved in the case. Nothing herein contained shall prevent West University Place from taking such other lawful action as is necessary to prevent or remedy any violation. SECTION H.
