Floods, Article IT, Flood Damage Prevention, to read as follows:

DIVISION 4. FLOOD PLAIN MANAGEMENT

Sections 34-97 -34-119. Reserved

Section 34-120. Statutory Authorization, Findings of Fact andPurpose.

(1) National Flood Insurance Program Compliance. ThisArticle is adopted to comply with the rules and regulations of the NationalFlood Insurance Program codified as 44 Code of Federal Regulations Parts59-78, as amended, so as to maintain the community’s eligibility in theNational Flood Insurance Program.

Section 34-121. General Provisions.

(1) Definitions. Unless specifically defmed below, words orphrases used in this Article shall be interpreted so as to give them the samemeaning as they have in common usage and so as to give this Article itsmost reasonable application.

1

. Accessory Use or Structure means a use or structure on the same lot with,and of a nature customarily incidental and subordinate to, the principal useor structure.

Flood Fringe means that portion of the 100 year flood plain outside of thefloodway.

Obstruction means any dam, wall, wharf, embankment, levee, dike, pile,abutment, projection, excavation, dredged spoil, channel modification,culvert, building, wire, fence, stockpile, refuse, fill, structure, stockpile ofsand or gravel or other material, or matter in, along, across, or projectinginto any channel, watercourse, lake bed, or regulatory flood plain whichmay impede, retard, or change the direction of flow, either in itself, or bycatching or collecting debris carried by floodwater.

(2) Annexations: The Flood Insurance Rate Map panelsadopted by reference into Section 34-37 may include floodplain areas thatlie outside of the corporate boundaries of the City of Piney Point Villageat the time of adoption of this Article. If any of these floodplain land areasare annexed into the City after the date of adoption of this Article, thenewly annexed floodplain lands shall be subject to the provisions of thisArticle irnniediately upon the date of annexation into the City.

(3) Severabili: If any section, clause, provision, or portion ofthis Article is adjudged unconstitutional or invalid by a court of competentjurisdiction, the remainder of this Article shall not be affected thereby.

Within the Floodway andFlood Fringe, all uses not listed as permitted uses in Section 34-123 shallbe prohibited. In addition, a caution is provided here that:

(a) New manufactured homes, replacement manufacturedhomes and certain recreational vehicles are subject to the generalprovisions of this Article and specifically Sections 3 4-123 and 34-93(5);

(b) Modifications, repair and maintenance, additions, structuralalterations or repair after damage to existing nonconformingstructures and nonconforming uses of structures or land are

2

regulated by the general provisions of this Article and specificallySection 34-127; and

(c) As-built elevations for elevated structures must be certified

by elevation surveys as stated in Section 34-126 of this Article.

Section 34-123. Permitted Uses, Standards, and Floodplain

Evaluation Criteria.

(1) Permitted Uses in the Floodplain. The following uses ofland are permitted uses in the 100 year floodplain as defined in theFederal Insurance Rate Map (FIRM) most recent revision:

(a) Any use of land which does not involve a structure, a fence,

an addition to the outside dimensions to an existing structure

(including a fence) or an obstruction to flood flows such as fill,excavation, or storage of materials or equipment.

(b) Any use of land involving the construction of newstructures, a fence, the placement or replacement of manufactured

homes, the addition to the outside dimensions of an existingstructure (including a fence) or obstructions such as fill or storage

of materials or equipment, provided these activities are located inthe flood fringe portion of the floodplain. These uses shall besubject to the development standards in Section 34-123(2) of thisArticle and the floodplain evaluation criteria in Section 34-123(3)

of this Article for determining floodway and flood fringeboundaries.

(2) Standards for Flood Plain Permitted Uses.

(a) Fill shall be properly compacted and the slopes shall be

properly protected by the use of riprap, vegetative cover or other

acceptable method. The Federal Emergency Management Agency

(FEMA) has established criteria for removing the special flood

hazard area designation for certain structures properly elevated onfill above the 100-year flood elevation FEMA’s requirements

incorporate specific fill compaction and side slope protection

standards for multi-structure or multi-lot developments. Thesestandards should be investigated prior to the initiation of sitepreparation if a change of special flood hazard area designation

will be requested.

3

(b) Storage ofMaterials and Eq24pment.

1. The storage or processing of materials that are, intime of flooding flammable, explosive, or potentiallyinjurious to human, animal, or plant life is prohibited.

2. Storage of other materials or equipment may beallowed if readily removable from the area within the timeavailable after a flood warning or if placed on fill to onefoot (1’) above the base flood elevation.

(c) No use shall be permitted that will adversely affect thecapacity of the channels or floodways of any tributary to the mainstream, or any drainage ditch, or any other drainage facility orsystem.

(d) All structures, including accessory structures, additions toexisting structures and manufactured homes (excluding“enclosures” as defmed in section 34-39 (3)), shall be constructedso that the lowest floor, including basement floor, is one foot (1’)or higher above the base flood elevation. This requirement amendsthe lowest floor elevation requirement in section 34-3 1 (1) and (2).

(e). Limitation of Lot Fill for Property located in the areas ofSpecial Flood Hazard. If the property is in a special flood hazardarea, the proposed improvements shall result in a no net increase involume of material on the lot with the exception of the smallamount of concrete material used on the lot for pier and beamraised foundation construction that may be permitted by thebuilding official. A topogr aphical survey performed under thesupervision of a Texas Registered Professional Land Surveyorshould be completed prior to the demolition of any structures onthe property to provide baseline conditions to determine theexisting volume of material on the lot for the property. Theelevations shall be based on current datum and vertical benchmarksystem being used by the City and should be at a maximumspacing of twenty five feet (25’) throughout the property. The Citywill provide, upon request, locations and elevations of benchmarksavailable within the City. The topographical survey shall includeas a minimum, the dimensions of all existing structures on the lot,the elevation of existing sidewalks, curb/gutters, ditches, stormsewers, sanitary sewers, elevations of slabs of existing structures,and the existing elevations of the lot. The Builder’s Engineerpreparing the drainage plan must provide supporting calculationsand supporting data demonstrating that no net increase in volumeof material is proposed.

4

(f Commercial and Manufacturing Uses. Accessory landuses, such as yards, railroad tracks, and parking lots may be atelevations lower than the one foot (1’) above the base floodelevation. However, a permit for such facilities to be used by theemployees or the general public shall not be granted in the absenceof a flood warning system that provides adequate time forevacuation if the area would be inundated to a depth and velocitysuch that when multiplying the depth (in feet) times velocity (infeet per second) the product number exceeds four (4) uponoccurrence of the base flood.

Section 34-124. Utilities, Railroads, Roads and Bridges within theFloodplain.

All utilities and transportation facilities, including railroad tracks,roads and bridges, shall be constructed in accordance with NationalFloodplain Insurance Program.

Section 34-125. Subdivisions.
