Ch 100 - Excavations

[History: Adopted by Planning Board: August 9, 1990; amendments noted where applicable. ]

100-1. Authority.

Pursuant to the grant of authority in RSA 155:E-11, the Planning Board of the Town of Conway, New Hampshire, hereby adopts these Excavation Regulations on August 9, 1990.

100-2. Purpose.

The purpose of this chapter is to control excavation to ensure  protection of public health, safety and welfare. clearly, the public interest is served by allowing the reasonable extraction of earth, but such excavations must not be allowed to cause "undue disruption of local land use plans and patterns" (New Hampshire Senate Bill 67-FN, 1989, adopted as Chapter 363). This chapter fulfills many public purposes, including making excavation sites safe during excavation operation; ensuring safe, usable and aesthetically acceptable reclaimed excavation sites; protecting natural resources, including but not limited to soil, water, flora and fauna; preventing land and water pollution; promoting soil stabilization; and protecting the productivity of agricultural land of national and state significance.

100-5. Permit approval procedures; annual extensions.

The first action an applicant should take is to read through this chapter. Copies are available at Town Hall, and a fee to cover printing costs shall be charged. By reading the rules, the applicant will know the town requirements and will be properly prepared to proceed with the application for an excavation permit. Failure to fulfill such requirements may result in unnecessary delays in obtaining a permit.
  1. Preliminary discussion. This initial step is optional, at the applicant's discretion, but is strongly recommended so that the applicant may get the Board's initial reaction to, and suggestions for, the project. The applicant may meet with the Board to discuss the project in general terms only, possibly specified and limited in RSA 676:4,II(a). Further detail in the discussion, including presentation of any plans, shall require proper public notice, as per RSA 676:4,II(b). However detailed the discussion, this phase is nonbinding on both the Board and the applicant.
  2. Application acceptance checklist. After preparing an application, the applicant shall meet with the Town Planner to review the application and related materials. The Planner shall review the application and related materials and shall complete the application acceptance checklist based on information provided at this meeting. The checklist is shown in Table One. If the applicant successfully meets the requirements of this checklist, the Planner shall schedule a public hearing with the Board, to be held within thirty (30) days. (NOTE: Successful completion does not constitute application acceptance by the Planning Board, but is merely a preliminary check prior to setting up a public hearing.) If the applicant fails to meet the requirements of this checklist, the applicant shall revise the materials as needed and repeat this step. The checklist and all application materials shall remain on file at Town Hall, available for public inspection.
  3. Public notice. Notice of the public hearing shall be sent by certified mail to the applicant, abutters and the Chairman of the Conservation commission. Such notice shall be published in a local newspaper and shall be posted at Town Hall, the Conway Post Office, the Center Conway Post Office and the North Conway Post Office. Notice shall state the date, time and location and shall precede the hearing by at least fourteen (14) days, not including the day of the hearing nor the day of posting or publication.
  4. Application acceptance. The Board's first action on the application shall be to review the application materials and the checklist to determine whether or not the application is complete. If the application is found to be complete, the Board shall vote to accept the application and begin formal consideration.&nIf 'the application is found to be incomplete, the Board shall vote to deny acceptance of the application on the basis of insufficient information, and the applicant shall return to Subsection B listed above.
  5. Public hearing. Upon determining that the application is complete and voting to accept the application, the Board shall ask the applicant to present a summary of the proposal to the Board and the public, then shall open a public hearing and shall ask for public input. This hearing shall not be closed until the Board is ready to approve, conditionally approve or deny the application. If additional time is necessary, the hearing shall be continued in accordance with Article IX of the Conway Planning Board Bylaws. To ensure proper control of the meeting, the Chairman may decide when further public input will be accepted and when it will be prohibited.
  6. Decision. Upon closing the public hearing or any continuations thereof, the Board shall approve, conditionally approve or deny the application within twenty (20) days. This twenty-day limit is set by RSA 155-E:7, and may not be extended.
  7. Excavation permit. Upon payment of all fees (See Ch 100-6), the posting of required financial security with the Board of Selectmen, and fulfillment of all other terms of the approval, an excavation permit shall be issued. This permit shall be valid for a period not to exceed one (1) year. However, an annual excavation permit extension may be granted as provided in Subsection H.
  8. Annual excavation permit extension. Once each year, the owner/operator of the excavation shall request in writing an administrative review of the permitted excavation. The applicant shall demonstrate compliance with the approved plans, that the financial security for each phase which will active during the upcoming year is in place and the approximate amount of earth remaining to be removed from the site and/or each phase. The Town Engineer and Town Planner shall conduct a site visit to review the information presented and shall issue an annual excavation permit extension. If noncompliance is evident, then the matter shall be brought to the attention of the Planning Board. The Board shall hold a pUblic hearing and shall make a final determination on compliance with the conditions of the permit.

100-6. Fees.

  1. Excavation fee. As provided by RSA 155:E:8, the applicant shall pay an excavation fee of fifty dollars ($50), made payable to "Town of Conway," to cover the costs of administering the application.

        2. Filled during site reclamation with material of similar porosity to that material removed, back to four (4) feet above the seasonal high-water table.
    2. The Board shall record a copy of such waiver with the Carroll County Register of Deeds and shall send a copy to WSPCD, with all related costs to be paid by the applicant prior to the issuance of the excavation permit.
  9. The applicant shall provide the town with a list of any hazardous materials which may be stored or used on the site. Such materials shall be handled and stored in accordance with state regulation and standards. All applicants shall provide evidence of environmental hazard/damage insurance prior to the issuance of the excavation permit and prior to the issuance of the annual excavation permit extension.
  10. Excavation of topsoil shall be prohibited on those sites identified in the Conway Master Plan as being farmland of national importance or farmland of state importance. Excavation of topsoil on other lands shall be allowed, provided that at least four (4) inches of topsoil is left on the surface of the entire site. Further, for excavation of materials under lands identified as farmland of state or national importance, all topsoil shall be retained on site and reclaimed as close to original as possible to maintain the agricultural productivity of the land.

100-11. Reclamation standards.

The town has both short- and long-term goals for excavation site reclamation. Short-term goals are to stabilize soils, preserve slopes and prevent erosion and pollution. Long-term goals are to provide the basis for the natural succession of vegetation and wildlife to take place on the site, ensure return of aesthetic qualities to the site and ensure continued success in meeting short-term goals specified above. The following reclamation standards are the minimum acceptable to the town:
  1.

    2. Where there are four (4) or more inches of topsoil on the undisturbed site, sufficient topsoil shall be retained and stockpiled on site to be used for site reclamation, with a minimum reclaimed topsoil depth of four (4) inches. The excess topsoil may be removed from the site for other use, except as prohibited in 100-10.J.

100-12. Waivers.

These regulations must be applied to each applicant in a fair and consistent manner. In certain instances, however, a waiver may be requested by the applicant if there is reason to believe that a particular requirement is inappropriate to the particular case.
  1. The applicant shall submit in writing to the Board a request for waiver at least fourteen (14) days before the scheduled meeting date. The request shall address the following:
    1. Provision to be waived.
    2. Explanation of how literal enforcement of the regulation would cause a hardship due to the unique characteristics of the site under consideration.
    3. Explanation of good cause for which the waiver may be granted, pursuant to RSA 155-E:5-b.
