Chapter 33
DEMOLITION PROCEDURES
|
3314.1 Completion. All demolition work shall be completed within
30 days from the commencing date of demolition. An extension of time
may be granted by the building official.
|
3314.2 Site work. A Construction Site Erosion and Sediment Control
(COSESCO) Demolition permit application must be obtained from the
Natural Resources Division of Public Works and submitted for review.
The fee for a COSESCO demolition permit is $75 per lot and is valid
for one year. By obtaining a COSESCO Demolition permit the contractor
agrees to meet the terms and specifications outlined in Section 13.38
of Davenport Municipal Code. And this section as follows:
|
3314.2.1 Site clearing. The demolition site shall
be cleared of all debris associated with the structures being removed.
All mechanical groundwork shall be removed from the site of demolition.
Foundation walls may be used as solid fill and in all cases shall
be removed or collapsed so as to allow burial below grade. Basement
and on grade concrete slabs shall be removed or substantially pulverized
to allow adequate drainage.
|
3314.2.2 Backfill and site finish. Demolition work
shall include site work as necessary to fill all excavations and to
create a smooth and even finish grade capable of supporting vegetation.
Materials and specifications for filling and final site work are as
follows: Only material that will not decompose in the ground shall
be used for filling all excavations to within one foot of the top
of the surrounding grade. The top one foot of fill material shall
be tillable soil, of which the formed aggregate does not exceed 1 1/2
inches. An earthen crown shall be provided at the center of the demolition
site to allow for proper site drainage. Final site work shall include
the spreading of a grass seed blend suitable for the site and able
to provide adequate ground cover and protection from erosion of soil.
|
3314.2.3 Excavations. The top and bottom of cut
slopes shall be made no closer than two feet to the site boundaries.
All excavated sites with a difference in elevation from the adjoining
grade level of 30 inches or more shall be filled and graded to a maximum
slope of two horizontal to one vertical. Sloped sites exceeding 12'
vertical height shall be graded to a maximum slope of three horizontal
to one vertical or shall be held in place by permanent retaining walls
equipped with guardrails. The Building Official may require engineered
designs for any retaining system.
|
3314.2.4 Utility abandonment. The demolition shall
not commence and no permit shall be granted prior to the abandonment
of the gas and electric and water service by the serving utility and
abandonment of the sewer service at the street, alley, or other location
as approved by the Department of Construction and Engineering. Care
must be exercised not to cut off any sewer or water service that may
serve another building or installation. A permit secured from the
Construction and Engineering Department will be required for the excavation
in a public way. The Building Official may waive this requirement.
|
SECTION 3315
MOVING OF BUILDINGS
|
3315.1 Permit authorization. No permit for foundation work,
excavation, or site development shall be granted by the building official
for the relocation of a moved building and no permit for moving of
any structure shall be granted without the written approval of the
Director of the Transportation Department. Such written approval shall
designate the approved route, designate the time and duration of the
move along public streets and any other restrictions deemed necessary
by the Director of Transportation. Such approvals shall be subject
to review by any public utility having property along the proposed
route. The Director of Transportation shall also notify the fire chief
and police chief of the intended route and shall continue such notification
for the duration of the moving, indicating any change in the route
and any pause in the moving procedure.
|
3315.2 Use of public right-of-way. No building or structure
shall be allowed to remain over night upon any street or public right-of-way,
nor shall any such moving restrict, at any time, access to any fire
hydrant or necessary emergency equipment.
|
3315.3 Notification. Every person receiving a permit to move
a building shall, within one day after the building reaches its destination,
report that fact to the Director of Transportation. The Director of
Transportation shall thereupon inspect the streets, alleys or public
ground over which the house or building has been moved and shall ascertain
the condition of same. If the moving has caused any damage to said
public right-of-way, repairs shall be made and all costs shall be
assessed against the party having been granted the permit for the
moving of the building or structure.

R310.1 "Emergency Escape and Rescue Required." Basements, habitable
attics and every sleeping room shall have at least one operable emergency
rescue opening. Such opening shall open directly into a public street,
public alley, yard or court. Where basements contain one or more sleeping
rooms, emergency egress and rescue openings shall be required in each
sleeping room, but shall not be required in adjoining areas of the
basement when so provided. Where emergency escape and rescue openings
are provided, they shall have a sill height of not more than 44 inches
(1118 mm) above an adjacent permanent interior standing surface. The
adjacent permanent interior standing surface shall be no less than
36 inches wide and 18 inches deep and no more than 24 inches high.
Where a door opening having a threshold below the adjacent ground
elevation serves as an emergency escape and rescue opening and is
provided with a bulkhead enclosure, the bulkhead enclosure shall comply
with section R310.3. The net clear opening dimension required by this
section shall be obtained by the normal operation of the emergency
escape and rescue opening from the inside. Emergency escape and rescue
openings with a finished sill height below the adjacent ground elevation
shall be provided with a window well in accordance with section R310.2.
Emergency escape and rescue openings shall open directly into a public
way, or to a yard or court that opens to a public way.

EXCEPTION: Basements used only to house mechanical equipment
and not exceeding total floor areas of 200 square feet
