[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
The quality of design of the urban area is dependent on the quality of design of individual plats and subdivisions that compose it. The arrangement of blocks and lots and the street system shall be designed to make the most advantageous use of existing topography and natural physical features, including tree masses and large individual trees. Adjacent properties shall be considered in the plat design and shall not be landlocked.
B. 
All street infrastructure design and construction shall comply with the standards and requirements set forth in these Regulations.
C. 
All street infrastructure development within residential and non-residential subdivisions shall integrate with the master street plan delineated in the City Comprehensive Plan to ensure greater accessibility by vehicle and pedestrian traffic and safely and efficiently transport projected traffic uses throughout the City.
D. 
Detailed construction standards for streets, sidewalks, driveways and curbs and gutters shall be based on the Design Criteria contained in these Regulations.
E. 
In the event that climatic conditions would delay the completion of any new street improvements, reasonable consideration shall be granted only by approval of the St. Robert Board of Aldermen.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
The developer has the duty of compliance with reasonable conditions laid down by the Planning and Zoning Commission and the Aldermen for the design, dedication, improvement and restrictive use of the land so as to conform to the physical and economical development of the City and to promote the safety and general welfare of the future lot owners in residential and non-residential subdivisions and of the community at large; the subdivision of land being a privilege conferred through these Regulations.
B. 
All successors or assigns shall be responsible for maintaining all common areas, improvements, infrastructures or facilities required by these Regulations or any permit issued in accordance with its provisions, until such time as the offer of dedication to the public has been accepted by the Board of Aldermen.
C. 
All streets and parking areas, curbs and gutters, street lighting, water and sewer lines and recreational and open space areas must be properly maintained so that they can be used in the manner intended; and any vegetation and trees required by these Regulations for screening or landscaping must be replaced if they die or are destroyed.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
A developer shall be required to complete all improvements and utilities required by the City Council and upon completion shall dedicate such improvements and utilities to the City, free and clear of all defects, liens and encumbrances on the property or public improvements dedicated.
B. 
Performance Contract. The City Council may require an agreement signed by the developer in which the developer guarantees completion of all required improvements within a period of time not to exceed twenty-four (24) months. The obligations of the developer under the agreement shall not be assigned without the express written consent of the City Council. Upon the breach of any part of the agreement by the developer, the City Council may at its option pursue any legal or equitable remedy necessary to ensure completion and payment by the developer for the required improvements and utilities.
C. 
Performance Bond. The City Council may require a performance bond or such other surety, as it may deem appropriate to secure such construction to be completed within a reasonable period specified by the City Council and expressed in the bond or other surety, in an amount and with surety and conditions satisfactory to the City Council.
D. 
Upon approval of a preliminary plat by the Board of Aldermen, all new streets, curbs and gutters, sidewalks, street lights and fire hydrants to be constructed within any new subdivision shall be completed in their entirety prior to the approval of the final plat of subdivision. The St. Robert Board of Aldermen, only upon favorable recommendation by the City Planning and Zoning Commission and by the filing of a performance bond or other form of surety as specified in Subsection (B) and Subsection (C) above, may waive this requirement. No building permit shall be authorized for issue nor shall any certificate of occupancy permit be issued for the occupancy of any building within the subdivision until all platted street improvements are completed and accepted by the City of St. Robert as previously stated herein or the proposed street improvements are guaranteed by the filing of a form of surety accepted by the City of St. Robert.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All developers shall be required to meet the minimum design and construction requirements of the City of St. Robert regardless of the street classification. Design requirements for all street improvements within the City of St. Robert are set forth in these Regulations.
B. 
In all new subdivisions, streets that are to be dedicated to public use shall be designed to adequately and safely handle projected traffic loads as provided for, by not limited to, the following:
1. 
The classification shall be based upon the projected volume of traffic to be carried by the street, stated in terms of the number of trips per day;
2. 
The number of dwelling units to be served by the street may be used as a useful indicator of the number of trips but is not conclusive;
3. 
Whenever a subdivision street continues an existing street that formerly terminated outside the subdivision or it is expected that a subdivision street will be continued beyond the subdivision at some future time, the classification of the street will be based upon the street in its entirety, both within and outside of the subdivision.
C. 
Streets that are to be dedicated to public use shall be classified as follows:
1. 
Local. A street whose sole function is to provide access to abutting properties. Cul-de-sac and loop streets are considered to be local streets.
2. 
Collector. A major street whose principal function is to connect local streets with collector or arterial streets, but that also may provide direct access to abutting properties.
3. 
Arterial. A major street in the City's street system that serves as an avenue for the circulation of traffic into, out of or around the City and carries high volumes of traffic.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
Access To Lots. Every lot shall be designed to provide a satisfactory and desirable building site and shall abut on a public street and a utility easement.
B. 
Access To Major Streets.
1. 
Arterial streets. Whenever a subdivision that involves the creation of one (1) or more new streets borders on or contains an existing or proposed arterial street, no direct driveway access may be provided from the lots within this subdivision onto the arterial street.
2. 
Collector streets. Similarly, to the extent practicable, direct driveway access to collector streets shall be minimized to facilitate the free flow of traffic and avoid traffic hazards.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All driveway entrances and other openings onto streets within the City of St. Robert shall be constructed so that:
1. 
Vehicles can enter and exit from the lot in question without posing any substantial danger to themselves, pedestrians or vehicles traveling in abutting streets, and
2. 
Interference with the free and convenient flow of traffic in abutting or surrounding streets is minimized.
3. 
Perform as an integral component of the curb and gutter system to properly channel all storm water runoff to the proper inlet collection device and prevent improper diversion of storm runoff towards any building or structure upon the lot that the driveway provides access to.
B. 
Specifications for driveway entrances are set forth in other Sections of these Regulations. If driveway entrances and other openings onto streets are constructed in accordance with the foregoing specifications and requirements, this shall be deemed as satisfactory compliance with the standard set forth in Subsection (A).
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All subdivision streets shall be designed and arranged to provide for the continuation of existing streets in adjoining subdivisions and, to the extent possible, the anticipated projections of streets through adjoining unsubdivided or undeveloped property to allow for convenient movement of vehicular traffic and the orderly development of adjoining property and shall adhere to the City's master street plan where applicable.
B. 
Major Streets. Arterial and collector streets through plats shall conform to the major street plan incorporated in the City of St. Robert Comprehensive Plan and the Design Criteria set forth in Chapter 804 of these Regulations. Major streets shall be continuous and in alignment with existing, planned or platted streets with which they are to connect. Wherever a plat abuts or is divided by a major street designated by the City Plan, whether any part thereof has or has not been dedicated or used by the public, the developer shall dedicate any lands within such plat that are necessary to provide conformity with the major street plan. Such dedication shall be shown on the plat and the developer shall receive no compensation for such dedication.
C. 
Local Streets. Local streets shall connect with surrounding streets (including existing, planned or platted streets) where necessary to permit the convenient movement of traffic between residential neighborhoods or to facilitate access to neighborhoods by emergency service vehicles or for other sufficient reasons, but connections shall not be permitted where the effect would be to encourage the use of such streets by substantial through traffic. Local residential streets shall be curvilinear in design to avoid non-conformity of lot appearance.
D. 
Cul-de-sacs, circles and loop streets are encouraged so that through traffic on minor residential streets is minimized. Cul-de-sacs shall be no longer than five hundred (500) feet and shall terminate in an open circular paved space having a minimum diameter of ninety (90) feet to outside of pavement or curb. No permanent paved surface or curb and gutter shall be required on the circle of a temporary cul-de-sac for a period of twenty-four (24) months where the street is to be dedicated for continuation beyond the temporary turning circle. Cul-de-sacs that are to be longer than five hundred (500) feet in length will require the construction of permanent intermediate turnarounds that are or do not exceed a maximum of five hundred (500) feet in spacing.
E. 
All permanent dead-end streets (as opposed to temporary dead-end streets, see Subsection (H) below) shall be developed as cul-de-sacs in accordance with the standards set forth in Section 800.050(D). Except where no other practicable alternative is available, such streets may not extend more than five hundred (500) feet (measured to the center of the turnaround).
F. 
Half-streets shall not be permitted.
G. 
Alleys. Alleys shall not be approved in residential districts, except where justified by special conditions, such as the continuation of an existing alley in the same block.
1. 
Where alleys are provided in residential areas, they shall be developed with a minimum right-of-way width of thirty (30) feet and the improved roadway shall be a minimum of eighteen (18) feet. Curb and guttering shall not be required for alleys within a residential area.
2. 
Alleys that are necessary for property that is to be developed for non-residential use shall have a minimum of a forty (40) foot right-of-way and the improved roadway shall be thirty (30) feet. Curb and guttering must be developed as an integral part of the finished roadway.
3. 
Dead-end alleys shall be avoided wherever possible, but if unavoidable, such dead-end alleys may be approved if adequate turnaround facilities are provide at the closed end.
H. 
Frontage Roads. Whenever a plat abuts or contains an existing or proposed major street or non-residential land use, the Planning and Zoning Commission may require frontage roads, screen plantings, deep lots or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic. Construction of all frontage roads will adhere to the same development criteria for public street improvements as delineated in other Sections of these Regulations.
I. 
Whenever connections to anticipated or proposed surrounding streets are required by this Section, the street right-of-way shall be extended and the street developed to the property line of the subdivided property (or to the edge of the remaining undeveloped portion of a single tract) at the point where the connection to the anticipated or proposed street is expected. In addition, the Planning and Zoning Commission may require temporary turnarounds to be constructed at the end of such streets pending their extensions when such turnarounds appear necessary to facilitate the flow of traffic or accommodate emergency vehicles. Notwithstanding the other provisions of this Subsection, no temporary dead-end street in excess of five hundred (500) feet may be created unless no other practicable alternative is available.
[Ord. No. 1711 §§1 — 3, 9-13-2004; Ord. No. 1739 §3, 12-20-2004]
A. 
Streets shall be related appropriately to the topography. In particular, streets shall be designed to facilitate the drainage and stormwater runoff objectives as set forth in Chapter 804 of this regulation and street grades shall conform as closely as practicable to the original topography.
B. 
Where unusual or exceptional conditions exist, the City Engineer may modify these requirements, however, in no case may streets be constructed with grades in excess of ten percent (10%), except that a local street may have a maximum grade of twelve percent (12%) when approved by the recommendation of the City Engineer.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
Block Length.
1. 
Intersecting streets, which determine lengths, shall be provided at such intervals as to provide adequate access and to meet existing streets in the neighborhood.
2. 
Where no existing plats are recorded, the blocks shall not exceed one thousand five hundred (1,500) feet in length except where topography or other conditions justify a departure from this maximum.
3. 
In blocks longer than eight hundred (800) feet, the Public Works Director may require pedestrian ways and/or easements through the interior of the block. Such pedestrian ways shall have a minimum width of ten (10) feet.
B. 
Block Width.
1. 
Interior blocks shall have sufficient width to provide for two (2) tiers of lots of appropriate depth.
2. 
Exceptions to the prescribed block width shall be permitted for exterior blocks that border the plat boundary or blocks adjacent to highways, major streets, railroads or waterways.
C. 
Large Blocks. When a tract is platted for subdividing into lots that are larger than normal building lots or parcels, such lots and parcels shall be arranged so as to permit the continuous extension and openings of future streets and appropriate resubdivision, with provision for adequate utility connections and easements for such resubdivisions.
1. 
Streets shall intersect as nearly as possible at right angles and no two (2) streets may intersect at less than sixty degrees (60°). Not more than two (2) streets shall intersect at any one (1) point.
2. 
Whenever possible, proposed intersections along one (1) side of a street shall coincide with existing or proposed intersections on the opposite side of such street. In any event, where a centerline offset (jog) occurs at an intersection, the distance between centerlines of the intersecting streets shall be not less than one hundred fifty (150) feet.
3. 
Local streets shall intersect with surrounding collector or arterial streets at safe and convenient locations.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
Street rights-of-ways are to be designed and developed to serve the following functions:
1. 
Carry motor vehicle traffic and, in some cases, allow on-street parking.
2. 
Provide safe and convenient passageway for pedestrian traffic.
3. 
Serve as an important link in the development's drainage system.
B. 
In order to fulfill these objectives, all public streets shall be constructed to meet the following general Design Criteria and as further designated by the guidelines set forth in these Regulations:
1. 
Collector street. The right-of-way shall be a minimum of sixty (60) feet wide and the improved roadway surface shall be thirty-six (36) feet wide (back-of-curb to back-of-curb). No parking shall be permitted for either side of the street.
2. 
Frontage street. The right-of-way shall be a minimum of sixty (60) feet wide and the improved roadway surface shall be thirty (30) feet wide (back-of-curb to back-of-curb). No parking shall be permitted for either side of the street.
3. 
Local street. The right-of-way shall be a minimum of fifty (50) feet wide and the improved roadway surface shall be twenty-eight (28) feet wide (back-of-curb to back-of-curb). Parking on either side of the street shall be regulated by separate ordinance as adopted by the St. Robert Board of Aldermen.
4. 
Cul-de-sac. The minimum right-of-way diameter shall be ninety (90) feet wide and the improved roadway surface radius shall be forty-five (45) feet wide (back-of-curb to back-of-curb).

[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All streets shall be constructed with curb and gutter and shall conform to criteria set forth in these Regulations.
B. 
Street widths shall be measured from back-of-curb to back-of-curb.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All new and existing sidewalks which are to be constructed or reconstructed shall be designed to enable persons with disabilities using wheelchairs to travel freely and without assistance by integrating a ramp into the curbing so that the sidewalk blends with street and driveway crosswalks at a common level.
B. 
Sidewalks shall be constructed along one (1) side of local and collector streets. The sidewalks required by this Section shall be five (5) feet in width. The grass median between the back-of-curb and the sidewalk edge parallel to the back-of-curb will be a minimum width of twenty-four (24) inches to allow for sufficient area for the placement of mailboxes and of street lighting.
C. 
Sidewalks shall be permitted to terminate at the curb line of the radius flare within cul-de-sacs.
D. 
Sidewalks shall not be required to be constructed within alleys and will not be permitted along arterial street right-of-ways unless recommended for approval by the City Engineer.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
All public street right-of-ways and other common areas or facilities in subdivisions shall be sufficiently illuminated to ensure the security of property and the safety of persons using such streets, sidewalks and other common areas of facilities. All street lighting costs will be borne by the developer.
B.

[Ord. No. 1711 §§1 — 3, 9-13-2004; Ord. No. 2048 §§1 — 2, 1-7-2008]
A. 
All sanitary sewer and water improvements and appurtenances to be constructed within public right-of-ways and dedicated easements shall conform to the requirements of these Regulations.
B. 
In addition to the specific criteria stipulated herein, the following additional regulatory guidelines are set forth as standard policy of the City of St. Robert Public Works Department:
1. 
All sanitary sewer mains constructed by the City shall terminate at the property line of the subdivision or land to be developed. Continuance of service mains shall be the responsibility of the developer/owner and the cost of such extensions to provide service shall be borne solely by the developer. All plans, specifications and construction permits shall be reviewed and approved by the City prior to the commencement of any improvements legally taking place.
2. 
All water service mains constructed by the City shall terminate at the property line of the subdivision or land to be developed. Continuance of service mains shall be the responsibility of the developer/owner and the cost of such extensions to provide service shall be borne solely by the developer. All plans, specifications and construction permits shall be reviewed and approved by the City prior to the commencement of any improvements legally taking place.
3. 
All buildings and structures requiring water and/or electrical service shall be individually metered. No multiple tenancy commercial plazas shall be authorized one (1) meter for the entire structure and all two-family and multiple-family units shall be individually metered without exception.
4. 
All pole-mounted and pad-mounted electrical transformers shall be constructed at the property line of the development, as determined by the Department of Public Works.
5. 
Any new building or upgrade of electrical service requiring single-phase electrical service over four hundred (400) amps and any new building or upgrade of electrical service requiring three-phase electrical service six hundred (600) amps and below shall have a main disconnect switch at the transformer as approved by the Department of Public Works.
C. 
Any waiver of the requirements set forth in Subsection (B) above shall be made only by the authorization of the City of St. Robert Board of Aldermen.
D. 
Final acceptance of any sanitary sewer or water infrastructure improvements will be considered only when all inspection, testing and as-built drawings are completed as required by these Regulations.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
All right-of-way developments shall provide a storm water drainage system that is designed in conformance with the Land Development Regulations and Chapter 804 of these Regulations.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
The developer shall be responsible for maintaining all improvements required by these Regulations or any permit issued in accordance with its provisions, until such time as the offer of dedication to the public has been accepted by the Board of Aldermen. This means that streets and parking areas, water and sewer lines must be properly maintained so that they can be used in the manner intended.
B. 
All pavement, surfacing, driveways, curb, walks, buildings, utility poles, guy wires and other surface structures affected by construction operations in connection with the performance of the development, together with all sod and shrubs in yards, parks and parking, shall be maintained and, if removed or otherwise damaged, shall be restored to the original condition by the developer.
C. 
The developer shall be responsible for any damage caused by settlement of backfill placed beneath pavements, street, road and driveway surfacing and drainage and other structures and beneath sod in yards, parking lots and parks, which may occur at any time prior to and during a period of one (1) year from and after the date of final acceptance of the work by the City of St. Robert; during such period the developer shall at his own cost and expense refill all excavations where backfill damage to structures, pavements, surfacing and sod caused by such settlement has occurred, to the satisfaction of the City. Should the developer fail to repair settlement that may occur as described above within thirty (30) days after being given notice thereof, the owner shall have the right to repair such settlement and charge the cost of such repairs to the developer.
D. 
The developer will be held responsible for all damage to roads, highways, shoulders, ditches, embankments, bridges, culverts and other property caused by him or any of his subcontractors in hauling or otherwise transporting materials to and from the several sites of the work, regardless of the location of such damage. The developer shall make arrangements relative to the payment for, or repair or replacement of, such damage or damaged surfaces or structures which are satisfactory and acceptable to the owners or owner of such damaged surfaces or structures or to their legally responsible officers, agents or other representatives, at the developer's own cost and expense.
[Ord. No. 1711 §§1 — 3, 9-13-2004]
A. 
Approval of a subdivision plat does not constitute formal acceptance by the City of St. Robert the offer of dedication of any streets, sidewalks, sanitary sewers, storm sewers, other utility infrastructures, parks or other public facilities shown on a plat.
B. 
The aforementioned offer of dedication will only be considered for acceptance by the Board of Aldermen when the developer submits a formal written request petitioning for acceptance of the street right-of-way to the Director of Public Works after all dedicated areas have been constructed in their entirety.
C. 
An affidavit from a registered engineer in the State of Missouri must accompany the developer's written request which shall affirm that all public improvements have been constructed in accordance with the standards and specifications of the original approved engineered plans and that all new streets have in fact been constructed within the platted right-of-ways and dedicated easements of the development. Any infrastructure improvements found to be constructed outside the duly platted right-of-way or easements areas will require the submittal of a duly recorded easement showing the Pulaski County Recorder of Deeds certification. Request will not be processed or considered unless all necessary easements are duly filed and a copy of such is filed with the Director of Public Works.
D. 
As-Built Construction Drawings. The developer shall submit construction (as-built) drawings to the Director of Public Works upon completion of the project and prior to final acceptance of the project by the City Council. The design engineer shall provide the City with one (1) set of prints for all infrastructure improvement projects corrected to show the project as constructed and shall accurately and completely denote all changes made during the course of the work. Each sheet within the plans shall be clearly marked as "Conforming to Construction Records" and shall include the date of revision and certifications by the engineer. Failure to provide the required documentation delineating the "as-built" construction of the improvements will delay the processing of the developer's request until compliance with this requirement is met. As-built plans shall contain the following graphical infrastructure improvements that were constructed to support the development:
1. 
Original platted street right-of-ways and dedicated easement alignments; and
2. 
"As-built" locations of all completed street roadways, curbs and gutters, sidewalks and driveway entrances; and
3. 
"As-built" locations of all completed sanitary sewer mains and service lines, water mains, natural gas lines and storm water conveyances; and
4. 
"As-built" locations of all water meters and valves, gas valves, manholes, storm water inlets, fire hydrants, street lights.
5. 
"As-built" finished road grade profiles and original profile grades.
E. 
The Public Works Director shall submit a copy of the developer's request and the engineer's affidavit to the Land Use Administrator for the purpose of scheduling the request with the Planning and Zoning Commission as is required by Chapter 89, RSMo. A written recommendation from the Director of Pubic Works shall accompany the documentation and shall summarize the acceptability of the plans, construction methods, testing and inspection results that are required by these Regulations.
F. 
The recommendations of the Planning and Zoning Commission shall be forwarded to the Board of Aldermen for their final review and approval of the offer of dedication by the developer. Upon the acceptance of the offer of dedication by the City Council, the bond may be released back to the developer in whole or in a portion thereof as determined by the City Council.
G. 
The developer shall remain and be held responsible for the abatement of any and all defects of the accepted dedicated areas for a period not to exceed twelve (12) months.
