ORDINANCE #15.65 RAZING OF BUILDINGS.
(1) PERMIT REQUIRED. No person shall hereafter raze any building in the City without first securing a permit therefor from the Division of Building Inspection and a permit for the sealing of the sewer from the Plumbing Supervisor. No permit shall be granted unless the applicant files a certificate of insurance with the Insurance Department giving evidence of liability insurance of $1,000,000 personal injury each occurrence, $1,000,000 aggregate, and $500,000 property damage each occurrence, $500,000 aggregate. The applicant shall agree to indemnify and hold the City harmless from all liability arising out of the job. Such insurance shall not be cancelled or reduced without 30 days prior written notice thereof to the Insurance Department. Such notice shall suspend the permit, and no work shall be done under such permit until a new insurance certificate complying with this subsection has been filed with the Insurance Department. A certificate of insurance shall not be required of a person seeking a razing permit if:
(a) The building is located in a residential zoning district and set back at least 10' from all property lines.
(b) The building is located in any zoning district, is an accessory building as defined in §13.02(1), Green Bay Municipal Code, is no greater than one story and is set back at least 10' from all property lines, or is constructed and situated upon the property so that the same may be razed with no damage resulting to the person or property of others as determined by the Building Inspector and Insurance Administrator. Anyone aggrieved by the determination of such Inspector and Administrator may appeal that decision to the Protection and Welfare Committee in accordance with Ch. 68, Wis. Stats.
(2) REQUIREMENTS. The holder of a permit to raze a building shall comply with the following requirements:
(a) Property to be Protected. Streets, alleys, and private property shall be properly protected by erecting proper fences and scaffolds. If scaffolds are to be built on streets or alleys, they shall be properly protected with a top cover of planks, guard rails, and toe-boards to prevent the falling of debris on sidewalks or streets. The top of the scaffold shall be at least 8' above the sidewalk or alley.
(b) Walls to be Supported. No person shall remove all horizontal support from exterior walls or partitions thereby permitting them to stand unsupported.
(c) Buildings to be Razed Floor-by-Floor. In buildings of more than one story, the exterior walls, interior partitions, and other supports shall be removed floor-by-floor, using the floor below as protection from falling debris and to prevent exterior and interior walls from collapsing.
(d) Razing to be Gradual. No walls, chimneys, or other construction shall be allowed to fall en masse on a floor; and bulky material such as beams and columns shall be lowered and not thrown.
(e) Cranes. Cranes may be used in wrecking or demolishing buildings provided the above requirements are complied with.
(f) Sewers. When a building is moved or demolished, its sewer shall be located at a point outside the foundation lines and sealed off. The plug or seal shall not be covered until approval has been given by the Plumbing Supervisor.
(g) Obstruction of Streets. When razing requires the obstruction of a public street, alley, or sidewalk, a permit must be obtained from the Director of Public Works as provided in §9.27, Green Bay Municipal Code, before starting work on razing of the structure.
(h) Filling Basement and Excavated Areas. All loose material and debris shall be removed from the basement, crawlspaces, and other excavated areas. Upon ascertaining that all openings, pipelines, drains, etc., have been properly capped, all basements, crawlspaces, excavated areas, and other below-grade voids resulting from the removal of pavements, slabs, foundations, and the like shall be filled to within 4 inches of finished grade with granular fill material. The material shall be well graded, free from debris and organic material. All granular fill shall be placed in layers of 12 inches or less and shall be compacted to not less than 95 percent of Modified Proctor (ASTM D-1557).
(i) Completion of Project. When razing activities are completed, the disturbed area shall be graded so that no gradients in disturbed earth shall be steeper than a slope of 3 to 1 (horizontal to vertical). A layer of arable topsoil capable of supporting perennial grasses shall be spread over the disturbed area to a minimum depth of 4 inches. The area shall be seeded with a perennial grass capable of survival in this climate and maintained until the area is stabilized and developed with zoning and other applicable provisions of the Municipal Code.
