[HISTORY: Adopted by the Mayor and Council of the Borough of Wenonah 12-11-2008 by Ord. No. 2008-26. Amendments noted where applicable.]
A construction permit shall not be issued until a grading plan has been reviewed and approved by the Borough Engineer, or the Combined Planning/Zoning Board in accordance with the provisions of this ordinance.
The requirements set forth herein shall apply to the development of all property within the Borough of Wenonah, whether for residential or nonresidential purposes. Expressly excluded from the requirements set forth herein is the construction of proposed additions to existing buildings or structures having, at grade for floor level, a total of 600 square feet or less of area.
An applicant for a construction permit permitting the development of any property in the Borough of Wenonah must provide a grading plan for each lot and property proposed to be developed. The grading plan shall contain all of the information required in the Grading Plan Checklist hereinbelow specified, which Checklist shall be made available to all applicants for construction permits. The applicant/developer must submit a completed Grading Plan and Checklist with the application for a construction permit.
The following shall be incorporated into a Grading Plan Checklist provided to all applicants for construction permits. All applicants must complete this Checklist and supply the required information on a plan prepared, signed and sealed by a professional engineer or professional land surveyor licensed in the State of New Jersey.
The Grading Plan Checklist is included as an attachment to this chapter.
The grading plan must conform to the following standards:
All gradings shall be done in a manner as to not result in any adverse effects to adjacent properties. The plan shall not increase the amount of water which drains onto adjoining lots. For properties where a drainage problem already exists, the drainage plan shall reduce the impact on adjoining tracts to the greatest extent possible by causing the surface water to drain to nearby streets, into approved drainage facilities or into other accepted devices. All lots shall be graded to direct surface water runoff away from structures and toward the frontage road or other defined drainage paths.
Lawn areas shall be sloped away from buildings and structures at a minimum of 5% for the first 10 feet from a foundation wall. A minimum slope of 1% should be maintained in all other lawn areas. A minimum slope of 2% shall be maintained for all swales. Swales are normally placed at the edge of both lots so that water will flow from the back of the house to the curb. Water also may be directed to flow on neighboring lots where easements are applicable to the curb or to the source where the water will be discharged.
All slopes shall be no greater than 3:1.
Driveway grades shall not exceed 10%.
No grading shall occur within five feet of a property line unless necessary to direct drainage off the site and into acceptable drainage facilities in accordance with the standards.
The top of any excavation of slope shall be no closer than five feet to an adjoining property and shall not provide for water runoff to the adjoining property unless an agreement shall have been provided and recorded in the form of an easement.
If a retaining wall is proposed, construction details must be provided. In cases where a retaining wall is higher than 48 inches, calculations prepared by a licensed professional engineer must be submitted certifying the stability of the structure.
Each person or entity to whom this chapter applies must obtain approval of his/her grading plan in the following manner:
In those applications within the jurisdiction of the Borough's Combined Planning/Zoning Board in the nature of site plan applications or major subdivision applications, site grading plans are required by applicable land use ordinances of the Borough. In such cases, the Combined Planning/Zoning Board shall have jurisdiction to approve such grading plans. In all other cases, grading plans shall be submitted to the Borough Engineer for review and approval prior to issuance of any application for construction.
The Borough Engineer shall inspect the final grade of constructed improvements or alterations to a property. No certificate of occupancy shall be issued until the Borough Engineer approves the final grade.
Following completion of all grading and drainage work, the applicant must submit two copies of an as-built survey, prepared by a New Jersey licensed surveyor or engineer, with final grades and a request for a final inspection. If any discrepancy exists between the grading plan and actual construction, the applicant will be required to perform any necessary site work to correct the deficiency. All as-built site work must be done in conformity with the approved grading plans. Any significant deviations may be approved only by the relevant approving agency or the Borough Engineer.
Following completion of all work and receipt of the as-built grading plan, the Borough Engineer shall conduct the final inspection and notify the Construction Official, in writing, whether the final construction is in compliance with the approved grading plan and that a certificate of occupancy may be issued. The Construction Official shall issue the certificate of occupancy only if all conditions for the approved grading plan have been satisfied.
All grading work shall be completed within 180 calendar days from the issuance of the building permit.
For lots not subject to review by the Combined Planning/Zoning Board, an individual grading plan shall be filed for each lot.
Any person or entity to whom this ordinance applies must pay the following fees to the Borough for review of the grading plan and inspection of the as-built plan and the completed improvements on any property, as follows:
Application fee. $300 payable at the time of submission of a grading plan (per lot) and the sum of $100 upon submission of any revised grading plan.
Inspection fee. A fee of $200 per lot to be used to defray the costs of the Borough Engineer's review and inspection of the site and the sum of $100 for any reinspection of the site. The fees of this subsection shall be paid prior to the site inspection of completed lot improvements required by this ordinance.
All ordinances inconsistent with the provisions of this ordinance be and are hereby repealed to the extent of such inconsistency.
All existing ordinances not inconsistent with the provisions of this ordinance are hereby saved from repeal. Should any section, clause, sentence, phrase or provision of this ordinance be declared unlawful or unenforceable by a Court of competent jurisdiction, all other parts or provisions of this ordinance shall be considered severable and deemed lawful and enforceable.
This ordinance shall take effect immediately upon passage, publication and as otherwise provided by law.
