Wilmore City Zoning Code

ARTICLE VIII

SOIL EROSION AND SEDIMENT CONTROL

8.1 FINDINGS OF FACT

The following findings of fact related to the causes of soil erosion are made:

  1. Significant erosion results from rainfall and runoff over unprotected soil. Erosion is increased by intense rainfalls, long slopes, steep slopes, and lack of adequate vegetative cover. These conditions are in part caused by or aggravated by improper construction, grading, or excavation which results in removal of natural ground cover without taking appropriate steps to control erosion problems.

Effective on: 1/1/1901

8.2 PURPOSES AND OBJECTIVES

The intent of this ordinance is to:

  1. Reduce soil erosion in Jessamine County.
  2. Provide procedures for submission, review and approval of erosion control plans to be submitted prior to soil disturbance.

Effective on: 1/1/1901

8.3 SCOPE OF COVERAGE

The following are included within the scope of this ordinance.

  1. Erosion Control Plans are required in the following circumstances:
    All persons submitting to the Jessamine County - City of Wilmore Joint Planning Commission Major Subdivision Plats or Development Plans must include a note on the Preliminary Plat or Development Plan stating that no grading, excavating, stripping, filling or other disturbance of the natural ground cover shall take place prior to approval of an Erosion Control Plan. An Erosion Control Plan shall be submitted after a Preliminary Plat or Development Plan has been approved.  Any persons disturbing the natural ground cover in an area for which there is an approved Erosion Control Plan shall conform to the requirements of such Plan without exception.
  2. Grading Permits are required in the following circumstances:
    All persons doing any grading, stripping, excavating, filling or otherwise disturbing the natural ground cover in an area for which no erosion control plan has been approved, must obtain a Grading Permit prior to commencing such work, unless exempted under Section 6.3(d). For any work or developments not requiring a fully developed Erosion Control Plan, a grading plan addressing at a minimum the handling of topsoil and off-site runoff during grading must be submitted in conjunction with the Grading Permit application.
  3. Exceptions
    No Grading Permit or separate Erosion Control Plan shall be required for the following: (Each subsection of this section shall constitute a separate, independent exception.)
    1. Finished grading and excavation below finished grade (a) for basements and footings of a single-family or duplex residential structure authorized by a valid Building Permit; (b) for accessory structures related to single-family residences or-duplex structures authorized by a valid Building Permit; (c) for retaining walls eighteen (18) inches or less; (d) for swimming pools; or (e) for cemeteries for human or animal burial, provided the disturbed material or fill is handled in such a manner as to conform to the approved Erosion Control Plan for the area or where no such Erosion Control Plan is in effect such work must be done in a manner which presents no significant erosion hazard.
    2. An excavation or fill provided it meets all of the following:
      1. Is less than four (4) feet in vertical depth at its deepest point as measured from the natural ground;
      2. Does not result in a total quantity of more than 100 cubic yards of material being removed from, deposited on or disturbed on any lot, parcel or subdivision thereof;
      3. Does not impair existing surface drainage, constitute a potential erosion hazard, or act as a source of sedimentation to any adjacent land or water course;
      4. Has no final slopes steeper than one (1) foot vertical in three (3) feet horizontal;
      5. Has proper vegetative cover re-established as soon as possible on all disturbed areas; and
      6. Has no fill placed on a surface having a slope steeper than five (5) feet horizontal to one (1) foot vertical.
    3. Accepted agricultural land management practices such a plowing, cultivation, construction of agricultural structures, ponds, waterways, nursery operations such as the removal and/or transplanting of cultivated sod, shrubs, and trees, tree cuttings at or above existing ground level, and logging operations leaving the stump, ground cover and root mat intact. Non-agricultural uses permitted in the A-1 zone are not excepted from the requirements of soil erosion and sediment control.
    4. Grading, on existing developed lots or parcels, provided it meets all of the following:
      1. The aggregate area(s) affected, or stripped at any one time does not exceed 8,000 square feet, and is not within a natural drainage way (i.e., designated floodplain);
      2. The grade change does not exceed eighteen (18) inches at any point and does not alter the drainage pattern;
      3. Proper vegetative cover is re-established as soon as possible on all disturbed areas; and
      4. The grading does not involve a quantity of material in excess of 100 cubic yards.
    5. Installation of approved subsurface sewage treatment systems, lateral sewer lines, geothermal systems, telephone lines, electricity lines, gas lines or other public service facilities.

8.4 PROCEDURES AND STANDARDS FOR APPROVING SOIL EROSION CONTROL PLANS AND FOR ISSUING GRADING PERMITS

  • Administrative Procedure
    Applications for approval of Erosion Control Plans and Grading Permits shall be submitted to the Administrative Officer of the Jessamine County-City of Wilmore Joint Planning Commission as specified in Sections 8.4(a) and 8.4(a)(2). The application shall contain the applicant's name and address and other relevant information requested on the application forms. It shall also contain a proposed Erosion Control Plan containing the information required by Section 8.4(b). The application must be signed by the owner of the property or an authorized agent, and the Erosion Control Plans must be certified by a registered professional engineer or licensed landscape architect if submitted in association with a Major Subdivision Plat or Development Plan.
    1. Request for Approval of Erosion Control Plans Associated with a Major Subdivision or Development Plan
      All Erosion Control Plans shall be reviewed by the Jessamine County-City of Wilmore Joint Planning Commission which shall approve or disapprove the Erosion Control Plan as a part of the Construction Plans submitted for all Major Subdivision Plats or Development Plans under the standards set by this ordinance. Such an approved Erosion Control Plan shall have the same status and effect as a Grading Permit and a separate Grading Permit shall not be required. Upon completion of the work required under an approved Erosion Control Plan, the Enforcement Officer shall certify on such Plan that the work has been completed.
    2. Application for Approval of Grading Permit
      Applications for approval of Grading Permits shall be filed with the Administrative Officer. The Administrative Officer shall review such plans and a Grading Permit shall be issued or denied by the Administrative Officer. Review of the decision of the Administrative Officer is available through the Board of Adjustment. Upon completion of the work required under an approved Grading Permit, the Enforcement Officer shall certify on the Permit that the work has been satisfactorily completed.
    3. Extension of Time
      Every approved Erosion Control Plan or Grading Permit shall expire six (6) months from the issuance of a Grading Permit or approval of an Erosion Control Plan. If work is not completed within the terms of the Permit, or work is not commenced within six (6) months after issuance, the Permit holder may request an extension. The Administrative Officer may extend the deadlines contained in the Plan or Permit respectively upon a showing by the applicant: a) that there is sufficient justification for the delay; b) that delay will not create a new erosion hazard or permit an existing one to continue; and c) that a new completion date has been set.
  • Contents of the Soil Erosion Plan
    For purposes of obtaining a Grading Permit or for coordination with a Major Subdivision Plan or Development Plan, an Erosion Control Plan containing the following information must be submitted, unless such information is available to the Administrative Officer in an acceptable form. This information must be supplied for the entire tract of land whether or not the property will be developed in stages. If the development occurs in stages the Erosion Control Plan shall be approved as a whole; however, after construction has begun on the initial stage the Administrative Officer or the Enforcement Officer must inspect the site prior to granting approval for the issuance of building permits for any other stage of construction.
    1. The Erosion Control Plan shall be drawn at a scale of 1" = 100' (or less) indicating
      1. the site location as well as the adjacent properties, and
      2. identification of any structure or natural feature on the land adjacent to the site and within 250' which has a significant impact on drainage or siltation controls.
    2. Property boundary bearings and distances for the site on which the work is to be performed.
    3. A soil survey or a description of the main soil types (available from the Jessamine County Soil Conservation District).
    4. The anticipated time of exposure of each area prior to the completion of effective erosion and sediment control measures.
    5. Existing topography at contour intervals not exceeding five (5) feet.
    6. Proposed topography at contour intervals not exceeding five (5) feet.
    7. Elevation, dimension, location, extent and the slope of all proposed grading.
    8. Location and identification of all site features (either man-made or natural) which have a significant impact on drainage or siltation controls.
    9. Plans and specifications for all drainage provisions, retaining walls, cribbing, planting, anti-erosion devices or other protective devices (whether temporary or permanent) to be constructed in connection with, or as a part of the proposed work, together with a map showing the drainage area of land tributary to the site and a statement explaining the amount of estimated runoff used to determine the design characteristics of any drainage device. Upstream drainage must be considered and explained if any adverse effect is possible.
    10. Plans for removal, re-contouring or other final disposition of sediment basins or other structural improvements or devices included in the plan.
    11. If a sedimentation basin is required, it should be designed by a registered engineer.
  • Factors Which Shall be Considered in Reviewing Applications for Erosion Control Plans and/or Grading Permits
    1. The development should relate to the specific site conditions.
    2. The plan should keep land grading and land disturbance to a minimum under the circumstances.
    3. Both surface and storm water drainage systems should be integrated to accommodate the increased runoff incurred during land grading.
    4. To prevent soil erosion, existing temporary and future protective vegetative cover should be emphasized.
    5. The plan shall coordinate grading operation and sediment control measures so as to minimize land exposure to erosion.
    6. Sediment basins below high sediment producing areas should be planned, installed and maintained as safety devices to catch and trap excessive sediment from the development site.
    7. The plan should utilize available technology to keep soil erosion to a minimum level.
    8. Retaining walls shall be planned, installed and maintained where slope is steeper than one (1) foot vertical in two (2) foot horizontal on excavated slopes, cuts or fills greater than four (4) foot vertical.
    9. Fill areas shall be engineered to be appropriate for intended use. Plan should include method for placement of large material such as concrete slabs or rock boulders with dimension greater than two (2) feet in any direction. Method of placement should be designed to prevent voids in fill which may cause shifting, sliding or settling of material.
