channeled directly into storm drains.
10.
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:
a.
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.
b.
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.
c.
Grading of slopes will require silt
fencing at intermediate levels to slow surface water, prevent rutting
and decrease erosion.
d.
Grading sites will require silting
basins to prevent mud from washing onto adjacent properties.
e.
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.
f.
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.
g.
The maximum uncompacted thickness
of layers of the fill to be compacted shall not exceed eight (8) inches.
h.
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.
i.

operations shall be stripped and piled for storage in an amount necessary
to complete finished grading only.
11.
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:
Paved areas—Two (2) feet below
subgrade
|
Lawn areas—Two (2) feet below
finished grade

in progress, the Director of Public Works may require any contractor
or subcontractor to post surety bond or insurance with the City to
guarantee the City for compensation for any damage to streets, curbs,
sidewalks, trees, landscaping or other public facilities.
B. Routes. The Director of Public Works shall,
at least two (2) working days before the commencement of work and
usage of the streets of the City, notify the contractor of the route
or routes to be used by such trucks and equipment. The contractor
shall be charged with the duty of seeing that the trucks or equipment
use only the route or routes designated by the Director of Public
Works. In the event of any emergency requiring a change in route or
routes, or if the Director of Public Works finds or determines that
any route or routes so designated are not safe or that excessive damage
is being caused to any street or streets in the City by such usage,
or if he/she finds the welfare of the City so requires, he/she may,
upon one (1) day's notice to the contractor in writing, designate
an alternate route or routes, and it shall thereupon be the duty of
the contractor to see that the trucks or equipment use only the alternate
route or routes so designated by the Director.

No. 1488 § 1, 2-25-2008]
A. Photographs. It shall be the duty of the
Director of Public Works, immediately prior to the time of designating
the route or routes or alternate route or routes as provided herein,
to examine the condition of the streets to be used and to take photographs
of the streets showing the condition of the pavement, curbs, sidewalks
and other physical features, which shall be dated and a memorandum
made of the location shown by each photograph. Within five (5) days
after termination of the use of the streets as herein provided, it
shall be the duty of the Director to have additional photographs made
and proper descriptive matter included therewith.
B. Inspection. In addition to the taking of
photographs before and after construction, the Director of Public
Works shall cause a thorough inspection to be made of the condition
of the pavement of the streets designated and used under the permit,
as well as the curbs and sidewalks, and shall make written reports

425.070 and
425.080, he/she shall notify the contractor that the City will hold the contractor liable for unusual wear and tear or damage to the streets, curbs and sidewalks resulting from such usage, and that acceptance of the route or routes by the contractor shall constitute an agreement on his/her part to pay the reasonable cost of restoring the streets, curbs and sidewalks in question to their original condition. Within thirty (30) days after termination of the contractor's usage of said route or routes under the grading permit, the contractor shall pay to the City an amount sufficient to reimburse the City for the expense of restoring the streets, sidewalks and curbs to their original condition.
[R.O. 1997 § 425.100; Ord. No. 207 § 10, 2-26-1996; Ord.
No. 1488 § 1, 2-25-2008]
A. Barriers At Construction Site. After new
excavation or construction is commenced on any lot or tract of land
in the City, and until sodding, planting, concreting, paving or other
final surfacing is in place which will avoid washing or spreading
of dirt and mud onto other property, sidewalks, curbs, gutters, streets
and the space between sidewalks and curbs, the owner of the property,
or the contractor or builder in charge of work, shall erect and maintain
temporary walls or other approved barriers to prevent such washing
or spreading of mud or dirt. At the end of each day, and as required
throughout the day, during the course of excavating or construction,
dirt and mud on the sidewalks, curbs, gutters and streets, and the
space between sidewalk and street, resulting from work must be removed.
B. Removing Mud From Vehicle Wheels. The owners,
contractors, subcontractors and builders, jointly and severally, shall
provide his/her personnel with shovels or other equipment as necessary
to remove dirt from the wheels of all vehicles leaving any grading
site where mud has accumulated on the wheels, before such vehicles
enter any public or private street of the City. It shall be unlawful
for any owner, contractor or subcontractor or builder to permit any
vehicles to leave such place with mud on the wheels which is liable
to be dispersed over any public or private street of the City, and
it shall be unlawful for any driver of a vehicle to enter upon the
public or private streets of the City without having removed or had
mud removed from the wheels prior to such entry. Each occurrence shall
be a separate offense.
C. Spilling Materials On Streets. The owners,
contractors, subcontractors and builders, jointly and severally, who
may load dirt, mud or other materials on any vehicle at any grading
site in the City, during construction or otherwise, shall so load
the same that no portion thereof shall be spilled or be liable to
be spilled on the streets of the City. It shall be unlawful for any
such person to permit any vehicle to enter upon the streets of the
City loaded in violation of this provision, and it shall be unlawful
for any driver to operate a vehicle on the streets of the City which
is loaded in such manner that it spills or is liable to spill mud,
dirt or other materials on the streets.
D. Boards Over Sidewalks. Boards, tracks or
other protection must be laid over sidewalks, curbs and gutters to
avoid dirt and mud accumulating therein as completely as possible
and to prevent breakage or damage to such installations of whatever
material constructed. Damage to walks, curbs and gutters will be repaired
by the contractor, or the Director of Public Works may cause to have
them repaired at the contractor's expense.
E. Waste Material. During the course of construction
or excavation, owners, contractors and builders are required to clean
up all paper, refuse, sticks, lumber and other building waste, and
all other waste material daily and to prevent the same from blowing
or otherwise being scattered over adjacent public or private property.
F. Planting Ground. Vacant property and improved
property, after grading and construction is completed, shall be sodded,
planted, concreted, paved or otherwise surfaced to avoid washing or
spreading of dirt and mud onto other property, sidewalks, curbs, gutters,
streets and the space between sidewalks and curbs prior to issuing
an occupancy permit.
G. Grading. Grading, including operation or
idling of equipment, shall be accomplished only between the hours
of 7:00 A.M. and sunset on weekdays and 8:00 A.M. and sunset on Saturdays
and Sundays, unless in the case of emergency or a limited extension
of hours is specifically granted by the Director of Public Works for
cause.

No. 1488 § 1, 2-25-2008]
A. All violations shall be corrected within
the time limit specified in the issuance of a written notice to correct.
Action to correct violations which require immediate action shall
be taken upon verbal notification of the contractor by the City. All
persons failing to comply with such notice shall be deemed in violation
of this Chapter.
B. Any usage of the permittee's surety shall
be followed by a written explanation by the Director of Public Works
or his/her designee describing the condition corrected and the funds
required to complete the corrective action.
C. Nothing in this Section shall prevent prosecution
of violations of this Chapter in the absence of, or in addition to,
the issuance of a notice of violation.
[R.O. 1997 § 425.120; Ord. No. 207 § 12, 2-26-1996; Ord.
No. 1488 § 1, 2-25-2008; Ord. No. 1607 § 1, 3-23-2009]
Violation of any provision of this Chapter shall be an offense punishable by a fine and imprisonment as set out in Section

[R.O. 1997 § 425.130; Ord. No. 207 § 13, 2-26-1996; Ord.
No. 1488 § 1, 2-25-2008; Ord. No. 1797 § 1, 3-28-2011]
A. 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.
B. 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.
C. 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).
D. 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.
E. 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.
1.
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.
2.
Each special use permit shall have
a separate cash deposit to guarantee backfilling, paving, and site
restoration in accordance with this Section.
3.
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.
4.
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.
5.
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.
6.
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.
F. 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.
G. Manner Of Making Excavations.
1.
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.
2.
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.
3.
Adequate provision for proper drainage
of the area surrounding the work shall be maintained at all times.
4.
At no time shall the maximum length
of an open trench be permitted to exceed five hundred (500) feet.
5.
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.
6.
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.
7.
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.
H. Manner Of Backfilling, Repaving And Site
Restoration.
1.
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.
2.
Substitution may be made for granular
backfill or pave restoration only with the specific approval of the
Director of Public Works in each instance.
3.
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.
4.
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.
5.
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.
6.
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.
7.
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.
8.
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.
I. All work shall be guaranteed from defects
for a period of one (1) year after the inspection.
J. 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.
K. 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.
L. 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.
M. 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.
N. 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.
[R.O. 1997 § 425.140; Ord. No. 217 §§ 1—2, 4-8-1996; Ord.
No. 1488 § 1, 2-25-2008]
A. 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.
B. 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.
