A. 
Where subdivisions contain areas within the floodplain, the subdivider shall provide all necessary information and plans needed to determine what improvements are necessary to properly develop the subject property, including contour intervals, drainage plans and flood abatement devices to protect the property from damage due to flood. The subdivider shall provide a certified engineer's statement that such improvements, when properly installed, will be adequate for proper development.

B. 
All new or replacement sanitary sewer facilities, private package sewage treatment plants (including all pumping stations and collecting systems) and water facilities located within a floodplain shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into the floodwaters. In addition, they shall be located and constructed to minimize or eliminate flood damage and impairment.
C. 
All utilities such as gas lines and electrical and telephone systems located within a floodplain shall be elevated where possible and constructed to minimize the chance of impairment during flooding.
D. 
Streets and sidewalks should be designed to minimize their potential for increasing and aggravating the levels of flood flow. Drainage openings shall be required to sufficiently discharge flood flows without unduly increasing flood heights.
[Amended 6-24-2025]
Where public sewer or water service exists within 500 feet of the proposed subdivision boundaries, the Administrator may require that it be extended to serve all lots within the subdivision unless such extension is unfeasible due to grade, topography or that the existing services are not adequate to serve the proposed subdivision. The cost of extending and installing all such sewer and water lines shall be the sole responsibility of the subdivider.
[Amended 6-24-2025]
A. 
Nothing in this chapter shall prevent the installation of privately owned water distribution systems or sewage collection and treatment facilities; provided, however, that any such installations must meet all the requirements of the State Water Control Board, State Health Department and any other federal, state or local regulation having authority over such installation.
B. 
In any subdivisions involving a private sewer and/or water system, the applicant must submit assurances satisfactory to the Administrator and the County Attorney that a property owners' community association or similar association has been legally established under which the lots within the area of the final plat will be assessed for the cost of maintaining and operating the private sewer and/or water system and that such assessments shall constitute a pro rata lien upon the individual lots shown on the final plat.
C. 
Every final plat of a division of land involving lots served by a private sewer or water system shall contain a statement by the subdivider which clearly states that all private sewer and/or water systems within the subdivision are not publicly maintained and/or operated and shall be collectively maintained and/or operated by the owners of all lots which are served by said private sewer and/or water systems.
D. 
Each deed of conveyance for a lot included in a subdivision served by a private sewer and/or water system shall include the following restrictions:
(1) 
The private sewer and/or water system is not publicly maintained and instead shall be maintained by all the owners of lots which are served by the private sewer and/or water system.
(2) 
The grantee is required to belong to a property owners' association responsible for the maintenance and/or operation of the private sewer and/or water system within the subdivision and is liable for payment of an annual assessment for the maintenance and operation of said private sewer and/or water system.
[Amended 6-24-2025]
A. 
All physical improvements, including private sewer systems, private water systems and Class III roads, required by the provisions of this chapter or as a contingency to approval of the final plat for the subdivision as platted shall be installed therein and thereon at the expense of the subdivider.
B. 
After approval of the preliminary plat and prior to consideration of the final plat, the subdivider may complete all required physical improvements, or, pending completion of the improvements, the subdivider shall execute and file with the Administrator an agreement and bond (or agreements and bonds) in an amount calculated and submitted by a certified engineer and approved by the Administrator to be equal to the approximate total cost of such improvements, with surety approved by the Administrator and the County Attorney, guaranteeing that the required improvements will be properly and satisfactorily installed within one year of the date of final plat approval. Said bond shall be payable to the county and held by the Administrator.
C. 
However, in lieu of such bond, the subdivider may place with the county a certified check, a deposit in escrow or a bank or savings and loan association's letter of credit on certain designated funds upon the same conditions as above if such security is approved by the Administrator and the County Attorney.
D. 
Failure to complete all required improvements to the satisfaction of the county within the one-year time period specified shall mean forfeiture of the bond or other security by the subdivider to the county for completion of the required improvements. An extension of the one-year time completion period may be granted once by the Administrator when a request by the subdivider is received, in writing, stating the reasons the original time period has not been complied with and stipulating a new estimated time period when the improvements shall be completed, which shall not exceed one year. The Administrator may require that the amount of bond be revised and/or the bond renewed prior to authorizing such extension. This extension shall only be granted when no adverse effect to the public health, safety, welfare or convenience will be suffered.
E. 
No final plat shall be approved unless and until such bond or security has been received and approved as in this section or all the required improvements are completed.
F. 
The Administrator shall release, either partially or fully, any bond, escrow, letter of credit or other performance guaranty required by the county under this section within 30 days after receipt of written notice by the subdivider or developer of completion of part or all of any facilities required to be constructed hereunder unless the Administrator notifies said subdivider or developer, in writing, of any specified defects or deficiencies in construction and suggested corrective measures prior to the expiration of said thirty-day period; provided, however, that the Administrator shall not be required to release such bond, escrow, letter of credit or other performance guaranty in an amount to exceed 90% of the actual cost of the construction for which the bond was taken until such facilities have been completed and accepted. For the purposes of this subsection, a certificate of partial or final completion of such facilities from a duly licensed engineer or from an appropriate governmental agency may be accepted without requiring further inspection of such facilities.
