Petitioners shall submit a completed and fully executed application to appear before the Planning and Zoning Commission, together with all fees, plats, plans and other required documentation, at least two (2) weeks in advance of the Planning and Zoning Commission meeting at which petitioner desires to present his/her petition. Such timely submittal, however, shall not constitute a guarantee that the subdivision will be placed on the agenda for the desired meeting.
Major Subdivision Procedure.
After holding the preliminary conference with the Director of Public Works, petitioners desiring a major subdivision must submit, together with their application to appear before the Planning and Zoning Commission and the proper fee, two (2) copies of a preliminary plat containing all information described in Section 410.030(A) below to the Director of Public Works for review and approval. The petitioner shall also submit at this time a copy of a certificate of title, or other documentation acceptable to the City Attorney, showing petitioner's legal interest in the property to be subdivided, together with any designation of agents desired by the petitioner. Preliminary plat review will not be started until the application, fee, plat and certificate of title have been received and dated by the Director of Public Works.
The Director of Public Works will review the preliminary plat for conformance to the requirements of the subdivision and zoning ordinances and to 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.

Failure to approve or reject the preliminary plat within sixty (60) days shall be deemed approval of the Commission.
The action of the Commission shall be noted on two (2) copies of the preliminary plat, along with the signatures of the Chairman and Secretary of the Commission and any conditions imposed by the Commission. One (1) copy shall be returned to the petitioner, and one (1) copy shall be retained by the Commission.
Approval of a preliminary plat by the Commission constitutes authorization for the petitioner to complete engineering designs and began preparation of the final plat. If desired, petitioner may, at his/her own risk, begin tree removal, grading and improvements; but petitioner should note that only approval of the final plat by the City Council constitutes approval of the subdivision for recording, the sale of lots or any other purpose. Petitioners should note that changes may be required 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 to any site construction already performed at their own cost.
Public/common use improvement plans.
After approval of the preliminary plat by the Planning and Zoning Commission, the petitioner shall submit two (2) bound sets of all public or common use improvement plans to the Director of Public Works for review and approval.

No subdivision plat shall be approved by either the Commission or by the Council unless it conforms to the following minimum standards and requirements:
Potential dwelling displaced by parks or open space.
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.
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.
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.
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:
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.
Intersections with a major street or collector street shall be designed as nearly as possible at right angles.
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.
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.
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.
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.
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.
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.
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.
Blocks adjacent to a major street shall be designed to minimize points of ingress and egress.
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.
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.
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.
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.
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.
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).
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.
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.
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.
Should the subdivider desire to provide an escrow agreement, it shall:
Be approved by the City Attorney as to legal form;
Upon approval by the City Council be executed by the Mayor;
Guarantee the improvements set forth in the approved final plat by providing for a deposit with an approved escrow depositary;
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;
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.
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.

Earth under the forms shall be securely compacted prior to placing of concrete.
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.
Mixing and placing concrete.
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.
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.
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.
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.
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.
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.
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.
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.
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.)
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.
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.
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.
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.
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.
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.
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.
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.
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.
Curing of the pavement shall be continued for not less than seven (7) days after placement of the concrete.
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.
Cold weather concreting.
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.
Opening to traffic.
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.
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 required to prevent tackiness or pickup under traffic, the exposed surface of the filler shall be dusted with hydrated lime or sawdust. Sand will not be permitted. Other methods of preventing pickup under traffic may be used when approved by the Director of Public Works. Poured filler shall not be placed when the air temperature in the shade is less than fifty degrees Fahrenheit (50°F).
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.
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.
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.
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.
Major streets or collector streets may be improved with a twenty-four (24) foot pavement and a six (6) foot all-weather disaster shoulder on both sides when there are no lots having direct access to such streets.
All lots less than three (3) acres in area to be created by subdivision shall be served by the City of Florissant water system. When the area cannot be immediately served by the City of Florissant water system, then the Council shall permit service by another public utility.
When the subdivision is to be served by the City of Florissant water system, the subdivider shall comply with the ordinances relative to payment for the installation of water mains and fire hydrants in the subdivided area.

The water mains and hydrants, when installed, shall become at once the property of the City of Florissant, and said City shall have exclusive control and use thereof, subject to the right of the residents of the subdivided area to be connected therewith, and subject to the ordinances governing the extension of water mains.
When the subdivision is to be served by another public utility, the subdivider shall show the Council prior to approval of the final plat that mains and hydrants have been installed or security provided in lieu thereof to the satisfaction of the public utility, and that hydrants have been located as required by the standards of the Missouri Inspection Bureau.
The subdivider shall install sanitary sewers and provide a connection for each lot. Such installations shall be in accordance with the standards and specifications of and before the improvement is started the plan therefor shall be approved by the Metropolitan St. Louis Sewer District and the Commission. If no existing outlet sewers are within reasonable distance, the subdivider shall make such provisions for the treatment or disposal of the sewerage as will satisfy the Metropolitan St. Louis Sewer District, City, State and County health officials and before the plat shall be approved, the subdivider shall present to the Commission an order from the Metropolitan St. Louis Sewer District, City and State or County health officials showing that the treatment or disposal facilities will properly care for and protect the health, safety and welfare of the existing and probable future population within the subdivision and surrounding area. In no event, however, shall the subdivider be required to install treatment facilities larger than 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 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 shall contain complete information as to the type, location, materials 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 prior to the commencement of the construction of such facilities. If said approval is not obtained, no future claim for excess sewer costs under the aforementioned ordinances will be considered by the City of Florissant.
Editor's Note--Ordinances 391 and 605 have not been set out in this volume but were saved from repeal and may be found on file in the office of the City Clerk.
