No further work shall be conducted except for site stabilization until any violations are corrected and all work previously completed has received approval by the Stormwater Management Officer or the Town Engineer or his/her authorized representative.

Stormwater management practice inspections. The Town of Yorktown Stormwater Management Officer is responsible for conducting inspections of stormwater management practices (SMPs). All applicants are required to submit as-built plans for any stormwater management practices located on site after final construction is completed. The plan must show the final design specifications for all stormwater management facilities and must be certified by a professional engineer.

Inspection of stormwater facilities after project completion. Inspection programs shall be established on any reasonable basis, including but not limited to routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; inspection of drainage basins or areas identified as higher-than-typical sources of sediment or other contaminants or pollutants; inspections of businesses or industries of a type associated with higher-than-usual discharges of contaminants or pollutants or with discharges of a type which are more likely than the typical discharge to cause violations of state or federal water or sediment quality standards of the SPDES stormwater permit; and joint inspections with other agencies inspecting under environmental or safety laws. Inspections may include, but are not limited to, reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater management practices.

Submission of reports. The Town of Yorktown Stormwater Management Officer may require monitoring and reporting from entities subject to this chapter as are necessary to determine compliance with this chapter.

Right-of-entry for inspection. When any new stormwater management facility is installed on private property or when any new connection is made between private property and the public stormwater system, the landowner shall grant to the Town of Yorktown the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection as specified in § 248-15C.

Special precautions.

If at any stage of the grading (at any development site), the Town Engineer or his/her authorized representative determines, by inspection, that the nature of the site is such that further work authorized by an existing permit is likely to imperil any property, public way, watercourse, or drainage structure, the Stormwater Management Officer, Town Engineer or his/her authorized representative may require as a condition of allowing the work to be done that such reasonable precautions be taken as are considered advisable to avoid the likelihood of such peril. Special precautions may include, but are not limited to, reducing the grade of exposed slope, construction of additional drainage facilities, berms, terracing, compaction or cribbing, installation of plant materials for erosion control, and recommendations to use a registered engineer, CPESC individual and/or geologist, which may make requirements for further work.

Where it appears that storm damage may result from incomplete grading on any construction site, work may be stopped and the permittee may be required to install temporary structures or take such other measures as may be necessary to protect adjoining property or public safety. On large developments or where unusual site conditions prevail, the Town Engineer may specify the time of start for grading and time of completion or may require that the operations be conducted in specific stages to ensure completion of protective measures or devices prior to the advent of seasonal rains.

§ 248-16 Performance guarantee; recordkeeping.

Construction completion guarantee. In order to ensure the full and faithful completion of all land development activities related to compliance with all conditions set forth by the Town of Yorktown in its approval of the stormwater pollution prevention plan, the Town of Yorktown may require the applicant or developer to provide, prior to construction, a performance bond, cash escrow, or irrevocable letter of credit from an appropriate financial or surety institution which guarantees satisfactory completion of the project and names the Town of Yorktown as beneficiary. The security shall be in an amount to be determined by the Town of Yorktown based on submission of final design plans, with reference to actual construction and landscaping costs. The performance guarantee shall remain in force until the surety is released from liability by the Town of Yorktown, provided that such period shall not be less than one year from the date of final acceptance or such other certification that the facility(ies) have been constructed in accordance with the approved plans and specifications and that a one-year inspection has been conducted and the facilities have been found to be acceptable to the Town of Yorktown. Per annum interest on cash escrow deposits shall be reinvested in the account until the surety is released from liability.

Maintenance guarantee. Where stormwater management and erosion and sediment control facilities are to be operated and maintained by the developer or by a corporation that owns or manages a commercial or industrial facility, the developer, prior to construction, may be required to provide the Town of Yorktown with an irrevocable letter of credit from an approved financial institution or surety to ensure proper operation and maintenance of all stormwater management and erosion control facilities both during and after construction, and until the facilities are removed from operation. If the developer or landowner fails to properly operate and maintain stormwater management and erosion and sediment control facilities, the Town of Yorktown may draw upon the account to cover the costs of proper operation and maintenance, including engineering and inspection costs.

Recordkeeping. The Town of Yorktown may require entities subject to this chapter to maintain records demonstrating compliance with this chapter.
