No grading permit shall be issued on any site where there is an existing uncured violation of any provision of the zoning, subdivision or other development regulations of the City of Wildwood.
Modifications. Any party seeking a permit may request a modification of any of the minimum standards set forth in Subsection (A)(7) or (8) hereof by filing a written request with the Director specifically identifying:
Erosion Control Design. Erosion control requirements shall include the following:
Soil stabilization shall be completed within five (5) days of clearing or inactivity in construction.
If seeding or another vegetative erosion control method is used, it shall become established within two (2) weeks or the site shall be reseeded or a non-vegetative option employed.
Techniques shall be employed to ensure stabilization on steep slopes and in drainageways.
Soil stockpiles must be stabilized or covered at the end of each workday or perimeter controls must be in place to prevent silt from the stockpile from leaving the site.
The entire site must be stabilized, using a heavy mulch layer or another method that does not require germination to control erosion, at the close of the construction season. No new grading shall commence after the close of the construction season and before the start of the next construction season, unless authorized by the Director of Public Works in accordance with Section 425.050(A)(9)(b) of this Chapter; except for minimum necessary grading for the foundation or basement of any building, structure or swimming pool for which a building permit has been duly issued.
Techniques shall be employed to prevent the blowing of dust or sediment from the site.
Techniques shall be employed to divert upland runoff past disturbed slopes.
Sediment Control Design. Sediment control requirements shall include:
Settling basins, sediment traps or tanks and perimeter controls.
Settling basins shall be provided for each drainage area within ten (10) or more acres disturbed at one time and shall be sized to contain one-half (0.5) inch of sediment from the drainage area and be able to contain a two-year, 24-hour storm. If the provision of a basin of this size is impractical, other similarly effective best management practices (BMP), as evaluated and specified in the Storm Water Pollution Prevention Plan (SWPPP), shall be provided.
Settling basins shall be designed in a manner that allows adaptation to provide long-term stormwater management as required by the City.
Settling basins shall have stabilized spillways to minimize the potential for erosion of the spillway or basin embankment.
Protection for adjacent properties by the use of a vegetated buffer strip in combination with perimeter controls.
Watercourse Design. Watercourse protection requirements shall include:
Encroachment into or crossings of active watercourses/riparian areas and wetlands shall be avoided to the maximum extent practicable. All City, State and Federal permits and approvals shall be obtained by a permit holder prior to beginning work authorized by a City grading permit.
Stabilization of any watercourse channels before, during and after any in-channel work.
If a defined watercourse is to be realigned or reconfigured, clearing and grubbing activities within fifty (50) feet of the watercourse shall not begin until all materials and equipment necessary to protect the watercourse and complete the work are on site. Once started, work shall be completed as soon as possible. Areas within fifty (50) feet of the watercourse shall be recontoured and revegetated, seeded or otherwise protected within five (5) working days after land disturbance activities have ceased.
All stormwater conveyances shall be designed according to the criteria of the St. Louis Metropolitan Sewer District (MSD) and the necessary MSD permits obtained.
Stabilization adequate to prevent erosion shall be provided at the outlets of all pipes and paved channels.
Construction Site Access Design. Construction site access requirements for land disturbance greater that one (1) acre shall include:
A temporary access road provided at all grading sites including a wash down area supporting all active sites.
The Department of Public Works may require other measures to ensure that construction vehicles do not track sediment onto public streets or be washed with wash effluent channeled directly into storm drains.
Compaction. All fills intended to support buildings or structures, sewers and conduits shall be compacted to a minimum of ninety percent (90%) compaction as determined by Modified Proctor, ASTM D-1775. Compaction of fills for these uses must be certified by a registered professional engineer at the owner's expense. Frequency of compaction tests is to be determined by the Director of Public Works. Compaction of other fills shall be required where necessary as a safety measure to aid in preventing the saturation, slipping or erosion of the fill. The requirements of the Director of Public Works for the compaction of fills shall include, but shall not be limited to, the following:
Areas to be graded by cutting or filling shall be rough graded to within two-tenths (2/10) of a foot of accepted elevation after allowance has been made for thickness of topsoil, paved areas and other installations.
The natural ground surface shall be prepared by removing topsoil and vegetation and by compacting the fill upon a series of terraces. Hillside or slope fills shall require plowing or scarification of original ground.
Grading of slopes will require silt fencing at intermediate levels to slow surface water, prevent rutting and decrease erosion.
Grading sites will require silting basins to prevent mud from washing onto adjacent properties.
If fill material moisture content is below the requirement for compacting to maximum practical density, water in the proper amount shall be added. If moisture content is too great, fill material shall be aerated by blading or other satisfactory methods to reduce moisture content.
Frozen materials or soft, mucky, friable, easily compressible materials shall not be incorporated in fills intended to support buildings, structures, sewers or conduits or in the embanked ends of fills. In heavy rain, interrupted work shall not be resumed until moisture content is satisfactory. Fill material shall not be placed, spread or rolled while the ground is frozen or thawing.
The maximum uncompacted thickness of layers of the fill to be compacted shall not exceed eight (8) inches.
Compaction shall be by tamping, sheepsfoot rollers, multiple wheel pneumatic or other type rollers. Rolling shall be continuous until the desired maximum density is obtained.
Topsoil disturbed by grading or building operations shall be stripped and piled for storage in an amount necessary to complete finished grading only.
Removal Of Timber, Rubbish, Etc. Timber, logs, trees, brush, vegetable matters and rubbish of any description shall be removed and disposed of so as to leave the disturbed area with a neat and finished appearance. Tree stumps, masonry and other obstructions shall be removed to the following depths:
Storm Water Pollution Prevention Plan (SWPPP) Required For Land Disturbance Greater Than One Acre In Area.

Permit Required. No person shall make or cause to be made any excavation in any public place, street, roadway, parkway, walkway, alley, right-of-way or easement (public area) without first obtaining a special use permit from the Director of Public Works except in case of public work done by the employees of the City or by any contractor under contract with the City. Each separate and distinct excavation shall require a separate special use permit. This Section shall apply to all persons, and to all private, public and municipal corporations.
Emergency Work. In cases where public health or safety is in danger or whatever excavations must be made on an emergency basis to eliminate hazards to persons, or to prevent interruptions in the utility services or to restore such services after an interruption has developed and the City is not open, the provisions of this Section relating to issuances of a special use permit prior to excavation shall not apply. In such case the person making the excavation shall notify the Police Department of the City that the emergency work is being commenced and the location thereof, and the work may proceed immediately. Final surfacing or temporary patches by the contractor shall not be placed until such time as the City has inspected and approved the backfill and issued a special use permit therefor. Application for a special use permit shall be made on the first day the City Public Works office is open after the emergency work is commenced.
Application And Permit Fee. Application for a special use permit as required in Subsection (A) of this Section shall be made on a form provided by the City, which application shall contain information regarding the purpose, location, and the size of the proposed excavation and the approximate time work thereon will be commenced, and shall state the length of time applicant estimates will elapse from the commencement of the work until complete restoration of the surface. Each excavation shall require a separate special use permit. The fee for each special use permit shall be twenty dollars ($20.00).
Posting Insurance. Before any special use permit is issued, the applicant shall furnish proof of adequate insurance and protection to the City against all claims for damages arising from the prosecution of the work, as provided in Subsection (F) of this Section.
Deposit. The application for a special use permit shall, in lieu of or in conjunction with the surety required by Section 425.040 of this Chapter, include a cash deposit to insure the applicant will backfill the excavation, repair the pavement, and restore the site in compliance with this Section.
The approximate cost of granular backfill, repaving operations, and general site restoration to be performed by applicant desiring to make an excavation will be estimated by the Director of Public Works at the time the application for a special use permit is submitted, and the cost so estimated shall be deposited with the City. The amount of the deposit shall be reasonably sufficient to secure the City against any damage or expense which may result from the applicant's failure to comply with the provisions of this Section. The amount of such deposit shall be based upon the location, purpose, and extent of the work. The minimum amount of deposit shall be one hundred dollars ($100.00) for any excavations in street, sidewalks or driveway pavement and then the minimum deposit shall be two hundred dollars ($200.00). The maximum deposit shall not exceed five thousand dollars ($5,000.00), except where unusual circumstances exist.
Each special use permit shall have a separate cash deposit to guarantee backfilling, paving, and site restoration in accordance with this Section.
The applicant is responsible for maintenance of the excavation for thirty (30) days. Settlement of the excavation or cracking, breaking, or rutting of the surface shall be prima facie evidence of improper backfill, which shall be replaced by the applicant or by the City with the cost paid out of the deposit.
If the work is completed satisfactorily, the deposit shall be refunded to the applicant within fifteen (15) days of the final inspection by the Director of Public Works or his/her authorized representative. The contractor is responsible for notifying the Director of Public Works of final completion of work. The final inspection will not be performed until the thirty (30) day maintenance period is over.
In the event the applicant fails to complete or correct the work required by this Section, the City may correct or complete said work; and the cost to the City shall be paid out of the deposit. In the event that such deposit is insufficient to pay for the City's cost, or if no deposit was retained, the applicant shall pay the excess cost to the City within thirty (30) days. Failure to pay said costs shall constitute cause to deny future applications for grading or excavation until any default is fully cured.
Failure of the applicant to call for the final inspection within one (1) year of the issuance date of the special use permit shall result in the deposit being forfeited by the applicant, and said deposit shall be paid to the City Treasury as general revenue.
Liability Insurance Or Bond. Every applicant for an excavation permit shall register with the City proof that the applicant is maintaining liability insurance in the sum of one hundred thousand dollars ($100,000.00) for bodily injury to each person, three hundred thousand dollars ($300,000.00) for bodily injury to all persons in one (1) occurrence arising out of or on account of excavation work on account of or in consequence of any neglect in safeguarding the work. Such insuree shall be carried in a firm or corporation which has been licensed or permitted to carry on such business in the State and shall be kept and maintained continuously in force and effect so long as the excavation work shall be in process. A verified copy of the insurance policy shall be filed with the City with the certificate of the insurer that the policy is in full force and effect and that such insurance will not be altered, amended, terminated or ended without notice having been given to the City. In lieu of the insurance as herein provided, the applicant may deposit a corporate or other surety bond in the penal sum of one hundred thousand dollars ($100,000.00) conditioned that he/she will pay any judgment recovered by any person injured or any property damage incurred on account of the excavation work or on account of or in consequence of any neglect in safeguarding the work. In the event the insurance policy provided for herein lapses and is not immediately renewed, or any bond terminates in any manner whatsoever and a substitute in lieu thereof is not deposited, the special use permit for such excavation shall be revoked immediately.
Manner Of Making Excavations.
In the making of excavations in any street or public space, the excavated materials from the trenches shall be placed where they will cause the least possible inconvenience to the public. If the excavated material is waste material, it shall be immediately removed from the site.
The width of excavation shall be no greater than is necessary for doing the work and sheathing and bracing shall be used as necessary to keep the sides of the trench vertical and to prevent caving. Excavations shall be made in accordance with City, County, State and Federal regulations.
Adequate provision for proper drainage of the area surrounding the work shall be maintained at all times.
At no time shall the maximum length of an open trench be permitted to exceed five hundred (500) feet.
No trench or pit shall be permitted to remain open without work actually in progress at each specific location for a period in excess of three (3) full working days, Saturdays, Sundays and legal holidays excepted.
Excavations shall be covered or fenced when work is not in progress. Excavations in roadways shall be backfilled or covered with steel plates at the end of the workday to allow traffic to safely cross over the excavation.
When a roadway is partially blocked by the excavation work, the applicant shall provide a flag person to direct traffic safely through the excavation site. Roadways shall not be closed except upon approval of the Director of Public Works after an approved detour has been established and properly signed, and after the Police and appropriate Fire Department have been notified.
Manner Of Backfilling, Repaving And Site Restoration.
Excavations made in or under the street, walk or driveway pavement shall be backfilled with granular material thoroughly tamped into place, and the pavement surface restored. In such locations, excavated materials shall be removed from the site of the work as the excavation is made, and no such materials shall be allowed to accumulate on the site.
Substitution may be made for granular backfill or pave restoration only with the specific approval of the Director of Public Works in each instance.
Approved granular backfill material shall be composed of one (1) inch minus crushed stone or gravel and sand, free from clay lumps and trash and conforming to industry standards for sieve analysis.
The granular backfilling material shall be at the excavation site at the time of the inspection by the City Inspector so he/she can determine compliance with aggregate specifications. Granular backfill shall be placed in horizontal layers not greater than six (6) inches thick before compaction and shall be densified by mechanical tamping or inundating and vibration or jetting. Each layer of fill material shall be compacted to ensure the desired compaction and density which shall be not less than ninety-five percent (95%) standard compaction. During placement, care shall be taken to avoid undue segregation of coarse and fine particles.
Asphaltic concrete pavement, macadam pavement, or bituminous pavement shall be restored as follows:
Excavation edges shall be cut straight to a minimum depth of two (2) inches and squared with a concrete saw. The edge shall be primed and an asphaltic concrete, St. Louis County Type C, shall be placed on the compacted backfill. The depth of asphaltic concrete shall be eight (8) inches placed in layers not greater than three (3) inches nor less than one (1) inch. Each layer shall be thoroughly compacted and the surface shall be smooth and free of ruts matching the existing pavement to support traffic without rutting or settling.
Concrete pavement shall be restored as follows:
Excavation edges shall be straight, cut full depth and squared with a concrete saw or replaced to a joint. A six (6) sack portland cement concrete shall be placed on the compacted backfill. The concrete thickness shall be seven (7) inches minimum. The concrete surface shall be finished to match the surrounding finishes. The concrete shall be protected from traffic for seven (7) days.
Curbs shall be restored as follows:
The existing remaining curb shall be cut straight with a concrete saw or removed to a joint. The new curb shall match (asphaltic concrete or portland cement concrete), shape, and style of the existing curbs. Concrete curbs shall be reconstructed with six (6) sack portland cement concrete.
Excavations in parkways, outside of the paved area may be backfilled with earth, and all grassed areas returned to their original condition by sodding or seeding as directed by the City. Earth backfill is to be placed and compacted in the same manner as described in this Section for granular fills or thoroughly jetted to obtain maximum settlement, and shall be maintained by the applicant until the area has been stabilized in the original condition. As soon as the excavation has been backfilled, all excess excavated materials shall be removed from the area and disposed of.
All work shall be guaranteed from defects for a period of one (1) year after the inspection.
Inspection Of Backfill Material And Pavement Replacement. Backfill material must be approved by a City Inspector. In the event backfill material is not approved by the City, all such backfill must be removed and replaced under a City Inspector's supervision. Pavement shall be replaced only upon inspection by the City.
Interference With Traffic And Driveways—Restoration Of Surfaces. All excavations regulated by this Section shall be made in such manner as not to inconvenience or interfere with the public use or travel upon the streets, sidewalks, or other public places when possible. When such use is unavoidably obstructed, the person making such excavation shall exercise all reasonable dispatch in prosecuting the work so that the public use will not be obstructed beyond a reasonable time. All sidewalks, crosswalks, curbs, gutters, streets, or public places disturbed, interfered with, or injured in making such excavation shall be restored, replaced, and repaired to as good condition as they were before such excavation was made.
Barricades, Signs, Lights, And Warning Signals. Every person who shall make or cause to be made any excavation in or adjoining on a public street, highway, or public place shall provide, erect, and maintain at all times along the line of work all such barricades, signs, lights, and warning signals as may be necessary to advise, warn, and protect the public from the hazards arising from the operation. All traffic control devices shall be in accordance with the Manual on Uniform Traffic Control Devices as published by the Federal Highway Administration.
Protection Of Public As To Excavations Near Public Ways. No person shall make, cause, or permit any opening near any public street, highway, alley or other public place to be left open and unguarded so as to be dangerous to persons passing along said street, highway, alley or other public place.
Inspections. Inspection fees for each inspection performed shall be forty dollars ($40.00). A minimum of one (1) inspection shall be required for each permit.

Unless action is taken by the City to the contrary, the City shall defer to the decisions of the fire districts having jurisdiction within the City of Wildwood regarding the location and number of public fire hydrants in each applicable fire district, except in such cases as the Director of Public Works determines that the City has different requirements with regard to specific locations or sites. The fire district authorizing or requiring any public hydrant shall forward such resolution to the Director of Public Works for the City, and unless the Director shall indicate objection to the resolution in writing to the fire district within twenty (20) days after such delivery, the City shall defer to the decision of the fire district for purposes as may be required by law for the authorization of such fire hydrants. No excavation shall occur within any public right-of-way or easement for installation of such fire hydrants until a special use permit or other required permit shall be obtained from the City of Wildwood.
Nothing in this Section shall be deemed to impose upon any fire district or any other party any requirement not already existing in law regarding the location or number of any fire hydrants, nor shall it be deemed to create any liability upon the City relating to any decision by the applicable fire district or any other party regarding such public fire hydrants. The City retains all authority and power under law to require, authorize or regulate public fire hydrants and nothing in this Section shall be deemed to modify or waive any applicable ordinances or regulations of the City.
