body
The Brazoria County Flood Plain recommends that permission be granted for the beachfront construction and dune protection of a single-family residence with fibercrete paving beneath the habitable structure, a crushed gravel driveway, and a septic system. The proposed construction is located within 200 feet landward of the line of vegetation. According to the Bureau of Economic Geology, the area is eroding at a rate of three to four feet per year.
Based on the information provided the following recommendations are made:
1) Cisterns, septic tanks, and septic fields are prohibited from being constructed seaward of any structure serviced by the cisterns, septic tanks, and septic fields. As proposed, the septic system plan appears to comply with this requirement.
2) The applicant proposes to construct a habitable structure seaward of the Building Setback Line, which is prohibited without an exemption from Brazoria County. To qualify for an exemption, the applicant must demonstrate to the satisfaction of the County that no practicable alternatives to construct seaward of the Building Setback Line exist.
3) The County must ensure the proposed construction is consistent with the FEMA-approved county Commissioners Court Order.
4) The County must limit the area of enclosures below BFE to 299 square feet and must ensure the enclosure is designed to minimize impacts to hydrology.
5) Should there be a change in project design, construction materials, or construction methods or in the condition of the construction site after the permit has been issued, the County shall require the permittee to apply for a new or amended permit or certificate.
6) Paving or altering the ground below the lowest habitable floor between the line of vegetation and 25 feet landward of the north toe of the dune is prohibited.
7) Paving areas beneath uncovered decks and stairs is prohibited. In the area 25 feet landward of the north toe of the dunes to 200 feet landward of the line of vegetation, paving used under the habitable structure and for a driveway connecting the habitable structure and the street is limited to the use of unreinforced fibercrete in 4-foot by 4-foot sections, 4-inches thick, separated by expansion joints, or pervious materials.
8) The applicant proposes to conduct construction activities directly adjacent to the critical dune area. The applicant must take measures to avoid adversely impacting dunes and dune vegetation during construction, such as temporarily installing silt fencing adjacent to the critical dune area to prevent construction equipment or materials from being placed in the dune system.
9) The County must ensure the proposed habitable structure is designed for feasible relocation.
Please be advised that structures may not encroach on the public beach. If the structure becomes located seaward of the line of vegetation because of loss of elevation, the structure may be allowed to remain in place if it does not significantly interfere with public access to the beach or present a public health and safety risk. Structures located seaward of the line of vegetation and landward of mean high tide may be allowed to make certain repairs under the Beach/Dune rules and local government plans.
If any part of a structure comes to be located seaward of the line of mean high tide, it becomes an unauthorized structure on state-owned land. Repairs are prohibited and the state may act to remove the structure.
Further, that a certified copy of this order be returned to the Flood Plain Administrator.
