current engineering practices and shall complete the appropriate portion
of the subdivision administrative review form. If the preliminary
plat does not comply with all requirements, one (1) copy will be returned
to the petitioner for correction and resubmittal with the deficiencies
indicated. If more than one (1) resubmittal is required, an additional
subdivision application fee shall be charged. When the Director of
Public Works has approved the preliminary plat, the petitioner shall

in the subdivision between approval of the preliminary plat and approval
of the final plat, such as addition or relocation of utility easements,
changes in the number, location or size of lots, or relocation of
street rights-of-way, and must be prepared to make necessary corrections

No subdivision
plat shall be approved by either the Commission or by the Council
unless it conforms to the following minimum standards and requirements:
1.Â
Potential dwelling displaced by parks or open space.
a.Â
When
parks or open space are included in the plat, the subdivider may provide
for that number of dwelling units that he/she would be permitted to
build under the zoning ordinance if no parks or open space were included
in the subdivision, but such dwelling units must be located within
that portion of the tract or parcel indicated for residential use
by the City plan. If offered to the City for dedication, such parks
may be accepted for dedication and maintenance.
b.Â
In
order that potential dwellings displaced by parks or open space can
be accommodated in the subdivision, the yard, height and lot size
established by the zoning ordinance for that tract or parcel can be
waived by the Commission. The Commission shall waive these requirements
only when it finds that the proposed subdivision makes good use of
topography and natural features, provides needed open space and contributes
variety and interest to the character of its neighborhood without
adversely affecting adjacent property. Requirements such as for side
or rear yard, replacing those that are waived under this provision,
shall be included in the subdivision plat or restrictions, and subsequent
replacement and extension of buildings shall be controlled by such
plat or restrictions.
2.Â
Streets.
a.Â
The
location, width and typical cross section of all streets shall conform
to the City plan and shall be designed to relate to existing and future
streets, to topographical and natural conditions, to public convenience
and necessity, to visual character, and to the proposed uses of the
land to be served by the street. The subdivider may be required to
continue adjoining streets through the area being subdivided when
necessary to provide for local movements of vehicles or to enable
adjoining property to be properly subdivided.
b.Â
Streets
shall have the following rights-of-way, except as increased or decreased
by the City plan or varied in unusual circumstances by the Commission:
c.Â
Where
a minor street is required to terminate in a circular open space,
said open space shall have a minimum radius of fifty (50) feet. Except
in unusual instances, no such street, including cul-de-sac, shall
exceed six hundred (600) feet in length.
d.Â
Intersections
with a major street or collector street shall be designed as nearly
as possible at right angles.
e.Â
Streets
may be retained as private streets or offered for dedication as public
streets, but the Commission may require that certain streets be dedicated.
Reserve strips controlling access are prohibited except when
control is placed with the City under conditions approved by the Commission.
Where streets are to be retained as private streets, they shall be
constructed to conform with the provisions of this Chapter relative
to dedicated streets, and all provisions of this Chapter shall apply
thereto, although continued to be maintained as private streets. All
escrow funds and any other provisions pertaining to streets contained
in this Chapter shall apply to the construction and maintenance of
private streets or streets that are to be maintained as private streets
after construction thereof.
f.Â
When
a subdivision abuts or contains an existing or proposed major street,
the Commission may require a frontage road, or on a major street reverse
frontage with a reservation of land along the rear property line through
which no access shall be permitted, deep lots with rear service alley,
or such other treatment as may be appropriate to separate through
and local traffic, to develop all major streets according to limited
access principles and to protect residential uses from through traffic.
3.Â
Easements.
a.Â
Easements
not less than five (5) feet wide shall be provided on each side of
all rear lot lines, and side lines where necessary, for poles, wires,
conduits, sanitary sewers, gas, water and heat mains, and storm sewers
and stormwater drainage improvements. Easements of greater width may
be required along lines or across lots where necessary for the extension
of mains, sewers, utilities and sidewalks or crosswalks. When alleys
are provided, utilities may be located within the alley.
b.Â
Whenever
any stream or surface drainage course is located in an area that is
being subdivided within the Metropolitan St. Louis Sewer District,
the subdivider shall dedicate an adequate easement as required by
the Metropolitan St. Louis Sewer District for the purpose of widening,
deepening, sloping, realigning, improving or protecting the stream
or surface drainage course.
c.Â
Where
any stream or surface drainage course is located in an area that is
being subdivided outside the Metropolitan St. Louis Sewer District,
the subdivider shall dedicate, as determined by the Commission, an
adequate easement for the purpose of widening, deepening, sloping,
realigning, improving or protecting the stream or surface drainage
course.
4.Â
Blocks.
a.Â
The
length, width and shape of blocks shall be determined with regard
to adequate building sites suitable to the special needs of the use
contemplated and the limitations and opportunities of topography.
b.Â
No
block shall be longer than fifteen hundred (1,500) feet between intersecting
streets. A crosswalk of ten (10) feet may be required when necessary
for pedestrian access and circulation.
c.Â
Blocks
adjacent to a major street shall be designed to minimize points of
ingress and egress.
5.Â
Lots.
a.Â
All
lots shall be designed to provide desirable building sites properly
related to topography, natural features, streets and land use. Except
as required below, the minimum area of any lot shall be that required
by the zoning ordinance, with no less than fifty (50) feet of width
at the building line, but larger or smaller lots than established
by the zoning ordinance may be required or permitted by the Commission
in order that private parks or open space can be accommodated as provided
by Section 410.050(1)(b), dwellings can be separated from major street
traffic as required by Section 410.050(2)(f), or as demanded by any
other standard, purpose or policy of the City plan or this Chapter.
d.Â
Where
a lot is located at the intersection of two (2) or more streets, extra
width shall be provided sufficient to permit the establishment of
front building lines on both the front and the side, or sides, of
the lots adjoining the street.
e.Â
Depth
and width of lots laid out for other than single-family dwelling purposes
shall be adequate for off-street service, parking and protection of
adjacent uses of streets.
6.Â
Building lines.
a.Â
Building
lines required by the zoning ordinance shall be shown on all lots
intended for residential use of any character and on non-residential
lots immediately adjoining residential areas.
b.Â
In
the interest of good design (to avoid monotony) or to meet other standards
of this Chapter or the City plan, the Commission may permit a variation
in the building line as required by the zoning ordinance for the district
in which the lot is to be located.
c.Â
The
subdivision plat or restrictions shall require that all enclosed parts
or buildings be set back of building lines. Yard and height restrictions
shall also be included when required by the provisions of Section
410.050(1)(b).
7.Â
Maintenance of common facilities. Where the subdivision
contains paving, sewers, sewage treatment plants, water supply systems,
park areas, street trees or other physical facilities necessary or
desirable for the common use or benefit which are not or cannot be
satisfactorily maintained by any existing public agency, provision
shall be made by trust agreement made a part of the deed restrictions,
or protective covenants acceptable to any agency having jurisdiction
over the location and improvement of such facilities, for the proper
and continuous maintenance and supervision of such facilities.
8.Â
Improvements. Before the final plat of any subdivided area
shall be approved by the City Council and recorded, the subdivider
shall make and install the improvements described in this Subsection.
In lieu of final completion of the minimum improvements before the
plat is finally approved, the subdivider may post a surety bond, irrevocable
letter of credit or escrow agreement approved by the City Attorney
of the City of Florissant, which bond, letter of credit or escrow
agreement will insure to the City that the improvements will be completed
in the event the subdivider abandons the subdivision or fails to install
the minimum improvements within two (2) years after the final approval
of the plat, whichever shall occur first. The amount of the bond,
letter of credit or escrow agreement shall not be less than the estimated
cost of the improvements, and the amount of the estimate must be approved
by the City Engineer. Said estimate shall be prepared by the subdivider
on forms furnished by the City of Florissant. If the improvements
are not completed within the specified time, the City Council may
use the bond, letter of credit or funds in escrow, or any necessary
portion thereof, to complete same.
a.Â
Should
the subdivider desire to provide a surety bond or letter of credit,
the bond form or letter of credit shall be in a form as approved by
the City Attorney.
b.Â
Should
the subdivider desire to provide an escrow agreement, it shall:
(1)Â
Be approved by the City Attorney as to legal form;
(2)Â
Upon approval by the City Council be executed by the Mayor;
(3)Â
Guarantee the improvements set forth in the approved final plat by
providing for a deposit with an approved escrow depositary;
(4)Â
Provide that the escrowed sum shall be held in special escrow account
by the escrow holder, subject to the audit of the City of Florissant;
(5)Â
The escrowed sum shall be held by the escrow holder, as in the agreement
provided, until such time as the Mayor shall, upon approval by the
City Council by written authorization addressed to the escrow holder,
release the escrow funds. In no case shall an authorization be given
for the release of more than seventy percent (70%) of the escrowed
sum allocated for each specific improvement or installation during
construction. When a specific improvement or installation has been
completed in accordance with the provisions of the ordinance and is
approved by the City Engineer, an authorization shall be given for
the release of a sum not to exceed an additional twenty percent (20%)
of the escrowed sum allocated for such specific improvement or installation.
Upon the completion of all improvements or installations in accordance
with the provision of this Chapter and approval and acceptance for
dedication and/or maintenance by the City Council, an authorization
shall be given for the release of the remaining ten percent (10%)
of the escrowed funds; provided however, that in the event that all
improvements or installations are completed except for ten percent
(10%) or less of the total amount of sidewalks remaining to be installed
in a subdivision, the City Council may approve and accept for dedication
and maintenance the streets of said subdivision and authorize the
release of all remaining escrowed funds upon the tendering by the
developer of a cash deposit to the City of Florissant in an amount
equal to one hundred twenty-five percent (125%) of the estimated contract
cost for installation of the remaining sidewalks in a subdivision
and further upon submission of a written agreement executed by the
developer guaranteeing the completion of the remaining sidewalks in
the subdivision within eighteen (18) months of the date of the approval
and acceptance for dedication and maintenance of the streets of said
subdivision and authorizing the City of Florissant, upon failure of
the developer to complete the sidewalks as indicated herein, to complete
the installation of the sidewalks, or contract for such installation,
and to use the cash deposit for payment of such installation.
(6)Â
Should the subdivider abandon the subdivision or fail to complete
the improvements within two (2) years from the date of the City's
approval of the final plat of the subdivision, whichever shall occur
first, except as provided in paragraph (5) above, the City may complete
or have completed the said improvements and the escrow holder shall
then disburse the escrow funds therefor as ordered and directed by
the Mayor upon approval of the City Council.
(7)Â
The form for said escrow agreement shall be as approved by the City
Attorney.
c.Â

is inadequate to obtain the results prescribed, shall be improved
or similar equipment substituted or added as directed by the engineer.
(ii)Â
The subgrade shall be cleared of large stones, sod, trees, roots,
rubbish and other debris. Holes and irregularities shall be filled
and compacted to uniform density and the subgrade shaped and finished
to conform to the lines and grades as shown on the plans. All soft,
loose or yielding material of the subgrade that will not compact when
rolled or tamped shall be removed and replaced with suitable material
placed and compacted as specified herein. The compacted subgrade
shall extend laterally a minimum of one (1) foot beyond the outer
limits of the forms. Fill materials shall be placed in layers not
exceeding six (6) inches in depth and be compacted by rolling, vibrating
or tamping to ninety percent (90%) maximum density according to ASTM
Test 698-65. The same density is required in cut section as in fill

(iii)Â
The approved subgrade and inspected forms shall be in place
and ready for paving not less than three hundred (300) feet ahead
of the paving operation.
(iv)Â
The subgrade shall be moist but not muddy when placing concrete.
(v)Â
Wash water from mixers will not be permitted on the subgrade
and will not be deposited in any drainage structures.
(g)Â
Forms.
(i)Â
Forms shall be true to line and grade and securely staked so
as to be unyielding during concreting operations. Top faces of forms
shall not vary from a true plane more than one-fourth (¼) inch
in ten (10) feet.
(ii)Â
Earth under the forms shall be securely compacted prior to placing
of concrete.
(iii)Â
The method of connecting form sections shall be such as to insure
a right, neat joint. Each time forms are used, they shall be cleaned
thoroughly and oiled before concrete is placed against them.
(h)Â
Mixing and placing concrete.
(i)Â
A uniform consistency of concrete shall be maintained at all
times. The concrete shall be consolidated by means of a vibrating
screed or an oscillating machine. If said screed does not impart
the necessary vibrating energy, in the opinion of the engineer, it
shall be improved or replaced to his/her satisfaction. The concrete
slump shall not exceed four (4) inches. Consolidation by hand will
be permitted only in special cases and then under the specific direction
of the engineer.
(ii)Â
Concrete may be mixed on the site in a batch mixer, mixed in
transit mixers or mixed in a central mixing plant. Sufficient notice
shall be given the Director of Public Works, prior to placing concrete,
of the method of mixing to be used so that mixing and delivery equipment
can be checked and approved for use.
(iii)Â
All longitudinal and transverse joints shall conform to the
detail as set out in the typical sections of these standard specifications.
These points shall be straight and perpendicular to the pavement
surface. The transverse joints shall be at right angles to the edge
of the pavement. Care must be taken to avoid over-finishing at joints.
(iv)Â
Concrete shall be placed between the side forms in successive
batches for the entire width of the construction lane to such elevations
above grade that when consolidated and finished, the surface of the
pavement shall be at the specified final grade elevations. It shall
then be thoroughly consolidated with the vibrating screed to the crown,
cross section and finished surface elevation indicated on the plans.
(v)Â
At the option of the Director of Public Works, the City may
sample and test for the cement content of the plastic concrete according
to the Willis-Hime method. If two (2) successive samples from loads
show a cement content of less than ninety percent (90%) of that required
in these specifications, the contractor must secure concrete from
another supplier or if the contractor is mixing the concrete on the
site, proper correction as approved by the engineer must be made to
the mix proportions to meet requirements of these specifications or
construction will be stopped.
(vi)Â
Transverse and dowelled construction joints (as indicated on
the typical sections) shall be installed at the close of each day's
work or when interruptions of more than thirty (30) minutes occur.
It shall be located at least five (5) feet from any other transverse
joint. It shall be formed from a clean wood plank, cut identical
with the cross section of the pavement with holes drilled for dowel
bars. The plank shall be accurately set and held securely in place
at right angles to the edge of the pavement. When operations are
resumed, the plank shall be carefully removed and all surplus concrete
or materials on the subgrade removed and fresh concrete deposited
directly against the old.
(vii)Â
The pavement surface shall be floated and straight-edged to
a true surface as called for on the plans. Finishing operations shall
be such as to require a minimum of manipulation from initial placing
to finished surface. The final pavement surface finish may be accomplished
by belting, brooming or burlap drag depending upon the wishes of the
engineer.
(viii)Â
Integral lib curb shall be cast monolithic with
the pavement. It shall be formed with a steel finishing tool known
as a "mule" fabricated to the exact cross section and dimensions set
forth in the curb detail in the typical section. Care must be exercised
to insure a well-defined outer section to accomplish complete drainage
to the nearest inlet structure in accordance with the plans. Incomplete
gutter drainage will be subject to correction at the discretion of
the engineer. Grades less than one and one-half percent (1½%)
shall be straight-edged with a ten (10) foot longitudinal straight
edge and a small level mounted on top and at the center.
(ix)Â
All joints shall be edged with a tool having an approximate
radius of one-eighth (1/8) inch, except in instances when the premolded
type contraction joint is used. (See typical section this detail.)
(x)Â
Final surface test. The contractor will be
held responsible for the correct alignment, grade and contour specified.
Any spots higher than one-fourth (¼) inch in ten (10) feet
for concrete pavements shall be ground to the required surface by
the contractor at his/her own expense.
(i)Â
Curing.
(i)Â
As soon as practicable after pavement is finished and without
marring the surface, the concrete shall be cured by a standard recognized
method with materials approved by the Director of Public Works; e.g.,
membrane spray, wet burlap, wet straw or watertight plastic cover.
(ii)Â
After the concrete has been finally finished and the water sheen
has left the surface, the entire area of the pavement surface shall
be sealed by hand spraying or machine spraying there on a uniform
application of the white pigmented membrane curing solution. The
solution shall be applied in one (1) or two (2) separate applications
as may be recommended by the manufacturer and as directed by the engineer.
If the solution is applied in two (2) increments, the second (2nd)
application shall follow the first (1st) application within thirty
(30) minutes.
(iii)Â
The contractor shall provide satisfactory equipment and means
to properly control and assure the direct application of the curing
solution on the pavement surface as to result in a uniform coverage
on the pavement at the rate of one (1) gallon for each two hundred
(200) square feet of area.
(iv)Â
White pigmented membrane curing compound shall conform to the
requirements of ASTM C-309-58 Type 2 all-resin base or the latest
revision thereof.
(v)Â
The curing solution shall be delivered to the job only in the
manufacturer's name, trade name of the material, and lot number with
which test samples may be correlated.
(vi)Â
If rain falls on the newly coated pavement before the film has
dried sufficiently to resist damage, or if the film is damaged in
any other way, the contractor will be required to apply a new coat
of material to the affected portions equal in curing value to that
above specified. All areas cut by finishing tools subsequent to the
application of the curing solution shall immediately be given new
applications at the rate of specified above.
(vii)Â
When joints are formed by sawing, the same method of curing
as applied to the pavement shall be reapplied to the freshly cut joints
as soon as practicable after the sawing operation.
(viii)Â
The contractor shall provide on the job sufficient
burlap for the protection of the pavement in case of rain or breakdown
of the spray equipment. In the event that hair-checking develops
before the membrane can be applied, wet burlap shall be used to cover
the surface of the pavement for not less than twenty-four (24) hours
before the membrane application.
(ix)Â
Curing of the pavement shall be continued for not less than
seven (7) days after placement of the concrete.
(x)Â
When forms are removed sooner than the seven (7) day curing
period, and when new concrete is not to be placed against the exposed
end, surfaces shall be treated with curing membrane.
(j)Â
Cold weather concreting.
(i)Â
Except by specific written authorization by the Director of
Public Works, concrete placing shall cease when the descending air
temperature in the shade falls below forty degrees Fahrenheit (40°F).
When concreting is permitted during cold weather, the temperature
of the mixed concrete shall be not less than fifty degrees Fahrenheit
(50°F) nor more than one hundred degrees Fahrenheit (100°F)
at the time of placing in the forms. The aggregates may be heated
by steam or dry heat prior to being placed in the mixer. The water
shall not be hotter than one hundred seventy degrees Fahrenheit (170°F).
When concrete is being placed during cold weather and the air temperature
may be expected to drop below thirty-four degrees Fahrenheit (34°F),
a supply of straw or other suitable blanketing material shall be provided
along the line of the work. Care must be exercised to prevent the
wind from removing same. At any other time when the air temperature
may be expected to reach the freezing point during the day or night,
the material so provided shall be spread over the concrete to a sufficient
depth to prevent freezing of the concrete. Such protection shall
be maintained for at least five (5) days. If required by the Director
of Public Works, concrete less than twenty-four (24) hours old shall
also be covered by approved devices capable of maintaining the temperature
within the concrete at fifty degrees Fahrenheit (50°F) or higher.
Concrete injured by frost action shall be removed and replaced at
the contractor's expense.
(k)Â
Opening to traffic.
(i)Â
The pavement shall not be opened to traffic or contractor's
equipment until so ordered by the Director of Public Works. The contractor
shall maintain adequate barricades and protection to the pavement
to prevent traffic from using the pavement until opened by the Director
of Public Works.
(ii)Â
Sealing joints. Joint filler shall be RC-3
hot-poured asphalt or its equal. The top of expansion joints and
all edged joints shall be sealed with the specified filler before
traffic is permitted on the pavement. The joint shall be surfaced
dried and thoroughly cleaned of all foreign matter before the sealing
material is poured. The filler shall be poured into the joint opening
to conform to the details shown on the plans or as directed by the
Director of Public Works. The pouring shall be done in such a manner
that the material will not be spilled on the exposed surfaces of the
concrete. Any excess filler on the surface of the concrete pavement
shall be removed immediately and the pavement surface cleaned. When

Poured filler shall not be placed when the air temperature in the
shade is less than fifty degrees Fahrenheit (50°F).
(l)Â
Thickness deficiencies.
(i)Â
General. It is the intent of these specifications
that the pavement shall be constructed strictly in accordance with
the thickness shown on the plans. The thickness of the pavement shall
be measured, and where any pavement is found not so constructed, such
pavement may be compensated for by reimbursing the City of Florissant
at a unit price per square yard or such pavement may be removed and
replaced with satisfactory pavement.
(ii)Â
Measurements. The thickness of the pavements
will be determined by the thickness of cores taken from the pavement
of such locations as the Director of Public Works may select. Three
(3) or more cores per lane will be taken in each one thousand (1,000)
linear feet of pavement and measured in accordance with ASTM C174-49.
The same rates of core locations will be selected over the entire
length of projects, where the total lengths [length] of the pavement
is less than one thousand (1,000) feet. Whenever any cores indicate
that the pavement is deficient in specified thickness, the contractor
will be notified. If any test core is found which is deficient in
thickness, additional cores shall be taken on each side of the place
from which the core is drilled, on a line parallel to the centerline
of the pavement until cores are found, on each side of the first (1st)
test core, which are not deficient. The intervals are to be selected
by the contractor and the Director of Public Works. All pavement
midway between the last test cores taken and the longitudinal joint
and the curb or between longitudinal joints will be considered as
being deficient, removed and replaced or compensated for as provided
below. If the contractors elect to drill additional cores, it will
be accomplished in the presence of an inspector, and the contractors
shall pay the additional cost of drilling.
(iii)Â
Drilling of cores and all work necessary and incidental thereto
will be considered inspection and will be charged against the inspection
fee deposited by the subdivision developers, other than additional
cores desired by the contractors as stated above.
(iv)Â
Compensation for thickness deficiencies when core measurements
[measurement] of thickness is found which is less than the thickness
shown on the plans, the reimbursements for deficiencies as shown on
the schedule below shall apply and will be paid to the City of Florissant.

are necessary to serve the land to be subdivided. A proposed subdivision
in an area to be annexed may be connected to existing sewers and payment
for maintenance or connecting charges and recovery of excess cost
shall be as provided for in Ordinances 391 and 605. Should the subdivider
contemplate the recovery of excess costs due to the installation of
certain sewer facilities as provided for in Ordinances 391 and 605[2] of the City of Florissant, said subdivider shall apply
for the recovery of said excess costs in writing to the Metropolitan
St. Louis Sewer District and to the City of Florissant. Said application

to be used, size, length, and any other factor pertaining to the facilities
to be installed, together with the estimated cost thereof. Said estimated
cost shall contain a breakdown as to materials, labor, services and
any other item considered part thereof. The approval of said application
by both the sewer district and the City Council shall be required
