Article I Excavations
[Ord. No. 646 §2, 8-19-1971]
No person shall make or cause to be made any excavation in any public way or place without first obtaining a permit from the City of Woodson Terrace as hereinafter provided, except public work done under the authority of the City by the employees of the City and except as otherwise provided in emergency cases. All work done by the employees of the Metropolitan St. Louis Sewer District shall be immune from the requirements of this Article regarding the payment of fees and submission of approved insurance policies. Each excavation shall require a separate permit for which a fee shall be paid.
[Ord. No. 646 §3, 8-19-1971]
Application for an excavation permit shall be made in writing to the Director of Public Works. Any person, firm or corporation applying for a permit under the ordinance shall pay the sum of ten dollars ($10.00) to cover the cost of the permit for the inspection of the street as hereafter provided. Application shall contain information regarding the purpose, location and size of the proposed excavation and the appropriate time when work on same will be commenced and completed. Before any 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 and shall deposit with the Finance Manager a cash bond of five hundred dollars ($500.00) for each excavation plus seven dollars ($7.00) additional for each square foot of excavation above ten (10) square feet.
[Ord. No. 646 §4, 8-19-1971]
In the making of excavations in any public way or place, the excavated materials from the trenches must be placed where they will cause the least possible inconvenience to the public. The width of excavation must be no greater than is necessary for doing the work, and sheathing and bracing must be used as necessary to keep the sides of the trench vertical and to prevent caving. Adequate provision for proper drainage of the areas surrounding the work must be maintained at all times. All excavations shall be in square or rectangular form. All concrete cuts shall be saw cuts and all pavement cuts of any kind shall be one (1) foot larger on each dimension than the excavation itself.
All excavations must be made in such manner as not to inconvenience or interfere with the public use or travel upon the public ways or places when possible. When such use is unavoidably obstructed, the person making such excavation must exercise all reasonable dispatch in progressing the work so that the public use will not be obstructed beyond a reasonable time. Where an excavation is made entirely across a public highway and adequate detour for traffic is not available, substantial driveway must be maintained across such excavation until such excavation is refilled. Detours may not be established except on special permit from the Director of Public Works, and then only after notice to the Fire Department and Police Department of the City. Any public ways or place disturbed, interfered with or injured in making any excavation must be restored, replaced and repaired to as good condition as it was before such excavation was made.
Every person who makes or causes to be made any excavation in or adjoining any public way or 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 protect the public from the hazards arising from the operation.
[Ord. No. 646 §5, 8-19-1971]
Excavations made in or under the street, walk or driveway pavements shall be backfilled with granular material thoroughly compacted into place, and the pavement surface restored to its original condition. In such locations excavated materials are to be removed from the site of the work as soon as practicable after the excavation is made and no such material unduly allowed to accumulate on the site.
Substitution may be made for granular backfill only with specified approval of the Director of Public Works.
[Ord. No. 646 §6, 8-19-1971]
Approved granular backfill material shall be composed of either crushed quarry rock or gravel and sand, free from any clay lumps, trash or dust sized particles. Other materials may be used only with the approval of the Director of Public Works. The maximum size of any material used shall not exceed one (1) inch. Quarry material or gravel or sand is to be placed in horizontal layers no greater in final thickness than six (6) inches and shall be densified by mechanical tamping or inundating and vibration. The minimum density of such material shall be at least one hundred five (105) pounds per cubic foot dry weight basis.
[Ord. No. 646 §7, 8-19-1971]
Excavations in parkways outside of the paved area of streets or walks may be backfilled with earth and all grassed areas returned to their original condition. Earth backfill is to be placed and compacted in lifts not over six (6) inches in initial thickness with pneumatic tamping at air pressure of at least eighty (80) P.S.I. on the surface of each lift a minimum of ten (10) seconds per square foot of area on all portions of the lift. As soon as the excavation has been backfilled, all excess excavated materials shall be removed from the area and disposed of. If granular fill is used, the granular fill shall not come closer to the surface than twelve (12) inches and shall be placed in accord with Section 510.050 above. The top twelve (12) inches of the fill will be made as outlined above with the shallower soil removed from the excavation.
[Ord. No. 646 §8, 8-19-1971]
Contractors and utility companies engaged in the construction, replacement or repair of utility lines in paved areas shall have the option of backfilling the trench with the excavated material in lieu of granular material, provided that the soil is not frozen when being replaced, has been protected by covering while excavated, the moisture content during backfilling is not greater than during excavating, has no individual lumps with a volume larger than eight (8) cubic inches, and provided that the material shall be backfilled and compacted in lifts no thicker than four (4) inches initial thickness with pneumatic tamping at air pressure of at least eighty (80) P.S.I. on the surface of each lift a minimum of thirty (30) seconds per square feet of area on all portions of the lift.
In the restoration of paved areas (including any street constructed with a soil-cement base), the type of materials used for the replacement of base and surface shall be the same as those which were removed, and such replacement shall be accomplished in compliance with the requirements of the Director of Public Works or his/her authorized representative.
All backfilling shall be fully completed within five (5) days of the making of any excavation unless for good cause shown the time is extended by the Director of Public Works.
[Ord. No. 646 §9, 8-19-1971]
Every applicant for an excavation permit shall register with the City proof that the applicant is maintaining liability insurance in the sum of two million dollars ($2,000,000.00) combined single limit for any injuries or damages received or sustained by any person, persons, or property on account of the excavation work or on account of or in consequence of any neglect in safeguarding the work. Such insurance must be carried in a firm or corporation which has been licensed or permitted to carry on such business in the State of Missouri, and must be kept continuously in force as long as the excavation work is in process. A verified copy of the insurance policy must be filed with the Director of Public Works, with the certificate of the insurer that the policy is in full force and effect and that said insurance will not be altered, amended, terminated or ended without notice having been given to the City.
[Ord. No. 646 §10, 8-19-1971]
In case of an emergency where the public health or safety is endangered and the office of the Director of Public Works is not open, the provisions of this Article relating to the issuance of permits prior to commencement of work of excavation shall not apply. In such case the person making the excavation shall notify the Police Department of the City that emergency work is being commenced and the location thereof, and the work may proceed immediately following the procedures herein above provided for backfilling; provided however, final surfacing or temporary patches shall not be applied to the excavation until such time as the Director of Public Works has inspected and approved the backfill and issued a permit therefore. Application for the permit shall be made on the first (1st) day on which the office of the Director of Public Works is open after the work is commenced.
