A. Permit Limitation: A grading permit shall constitute an authorization to do only that work which is described or illustrated on the application for the permit or on the plans and specifications approved by the designated official. The issuance of a permit, based upon drawings and specifications shall not prevent the designated official from thereafter requiring the corrections of errors in said drawings and specifications or from stopping unlawful construction operations being carried on thereunder.
B. Jurisdiction Of Other Agencies: Permits issued under the requirements of this chapter shall not relieve the owner of responsibility for securing permits for work to be done which is regulated by any other governing agency or entity.
C. Permit And Plans On Site: One (1) set of approved plans and specifications, setting forth all conditions attached, shall be kept on such grading site by the permittee at all times during which the work authorized thereby is in progress. The permit shall be kept posted so it is easily visible, or must be readily available upon request.
D. Pre-Construction Meeting: Prior to any grading work being started the contractor shall schedule with the City a pre-job meeting. Required attendees shall be owner representative, grading contractor and City Inspector; recommended attendees include Soils Engineer, Civil Engineer, any contractor involved with grading or utilities.
E. Time Limits:
1. The permittee shall fully perform and complete all of the work required to be done pursuant to the grading permit within the time limit specified. If no time limit is specified, the permittee shall complete the work within one hundred eighty (180) days after the date of the issuance of the grading permit.
2. If the permittee is unable to complete the work within the specified time, he/she shall, prior to the expiration of the permit, present in writing to the designated official a request for an extension of time, setting forth the reasons for the requested extension. If, in the opinion of the designated official, such an extension is warranted, then an extension of time, not to exceed one hundred eighty (180) days, may be granted for the completion of the work.
F. Drainage Precautions: All persons performing any grading operations shall put into effect all safety precautions which are necessary in the opinion of the designated official and provide adequate anti-erosion and/or drainage devices, debris basins, or other safety devices to protect the health and welfare of the community and property. Unless otherwise recommended by a registered design professional, drainage facilities and terracing shall be provided in accordance with the requirements of this section.
Exception: Drainage facilities and terracing need not be provided where the ground slope is not steeper than one unit vertical in three units horizontal (33 percent slope) or where slopes are intended and designed by a Geotechnical Engineer to be temporary or sacrificial in nature.
1. Terraces at least six feet (6') in width shall be established at not more than thirty foot (30') vertical intervals on all cut or fill slopes to control surface drainage and debris. Suitable access shall be provided to allow for cleaning and maintenance.
2. Swales or ditches shall be provided on terraces. They shall have a minimum gradient of one unit vertical in twenty units horizontal (5 percent slope) and shall be paved with concrete not less than three inches (3") (76 mm) in thickness, or with other materials suitable to the application. They shall have a depth not less than twelve inches (12") (305 mm) and a width not less than five feet (5') (1524 mm).
3. A single run of swale or ditch shall not collect runoff from a tributary area exceeding thirteen thousand five hundred (13,500) square feet (1256 m2) (projected) without discharging into a down drain.
G. Excavations:
1. Maximum Slope: Temporary cut slopes for construction purposes shall be no steeper than allowed per OSHA standards. The slope of permanent cut surfaces shall be no steeper than is safe for the intended use, and shall be not more than one unit vertical in two units horizontal (50 percent slope) or more than ten feet (10') in height unless the owner or the owner's authorized agent furnishes a geotechnical report justifying a steeper and/or higher slope.
2. Exceptions:
a. A cut surface shall be permitted to be at a slope of 1.5 units horizontal to one unit vertical (67 percent slope) provided that all of the following are met:
(1) It is not intended to support structures or surcharges.
(2) It is adequately protected against erosion.
(3) It is no more than eight feet (8') (2438 mm) in height.
(4) It is approved by the Building Code Official.
(5) Ground water is not encountered.
b. A cut surface in bedrock shall be permitted to be at a slope of one unit horizontal to one unit vertical (100 percent slope).
H. Conditions And Approval: In granting any permit under this chapter, the designated official may attach such conditions as may be reasonably necessary to prevent creation of a nuisance or hazard to public or private property. Such conditions may include, but shall not be limited to, the following:
1. Compliance with dust control requirements of the Clark County Department of Air Quality and Environmental Management.
2. Requirements for fencing of excavations or fills which would otherwise be hazardous.
3. Improvements of any existing site condition to bring it up to the standards of this chapter.
4. Compliance with erosion control requirements of Nevada Division of Environmental Protection Bureau of Water Pollution Control and other best management practices.
5. Haul routes for materials.
I. Unlawful Grading: The designated official shall not issue a permit in any case where the work, as proposed by the applicant, will endanger any private or public property or result in the deposition of debris on any public way or seriously interfere with any existing drainage course. However, if it can be shown to the satisfaction of the designated official that the hazard would be essentially eliminated by the construction of retaining structures, buttress fills, drainage devices or by other means, the designated official may issue the permit after the applicant has complied with subsections 8-2-5B and C of this chapter.
J. Warning And Disclaimer Of Liability:
1. Neither the issuance of a permit under the provisions of this chapter, nor the compliance with the provisions hereof or with any conditions imposed by the designated official, shall relieve any person from any responsibility for damage to persons or property otherwise imposed by law, nor impose any liability upon the District and entity for damage to persons or property.
2. The designated official, or his designee, charged with the enforcement of this chapter, acting in good faith and without malice for entity or District in the discharge of his duties, shall not thereby render himself liable personally and he is hereby relieved from all personal liability for any damage that may accrue to persons or property as a result of any act required or by reason of any act or omission in the discharge of his duties.
K. Hazardous Conditions: Whenever the designated official determines that any existing or proposed excavation, slope or fill has become a hazard to life and limb, endangers property or adversely affects the safety, use or stability of a public way or drainage channel, the owner of the property upon which the excavation or fill is located, or other person or agent in control of said property, upon receipt of notice in writing from the designated official, shall within the period specified therein repair or eliminate such hazard and be in conformance with the requirements of the policies and plans.
