[Ord. No. 2118 §§1 — 3, 8-18-2008]
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.
B. 
Adjacent properties shall be considered in the plat design and shall not be landlocked.
C. 
All street infrastructure design and construction shall comply with the standards and requirements set forth in the infrastructure development regulations on file with the Department of Public Works.
D. 
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.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
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, but 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.
B. 
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. 2118 §§1 — 3, 8-18-2008]
A. 
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. 
Non-residential, multiple-family and mobile home developments shall be permitted two (2) access drives that adjoin a public street.
C. 
Residential lots shall be permitted one (1) access drive that adjoins a public street, but a second (2nd) drive access may be permitted with the approval of the Director of Public Works. No residential lot shall be authorized more than two (2) access drives that abut a public street.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
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.
B. 
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. 2118 §§1 — 3, 8-18-2008]
A. 
All driveway entrances and other openings onto streets within the City of St. Robert and maintained by the City shall be constructed in accordance with the regulatory requirements set forth in Section 416.039 of these regulations and the construction standards set forth in the St. Robert Infrastructure Development Regulations.
B. 
The construction of driveway entrances that abut the right-of-way controlled by the Missouri Department of Transportation (MODOT) will be constructed in accordance with the standards of accessibility as promulgated by MODOT. Permits for right-of-way access on State-maintained roads are the explicit authority of MODOT and copies of said permits will be submitted to the City of St. Robert as part of the final engineering plans that are required by this regulation.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
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 with the major street plan incorporated in the City of St. Robert Comprehensive Plan and the design criteria set forth in the City's Infrastructure Development 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 which 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 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 curb and gutter shall be required on the circle of a temporary cul-de-sac where the street has been dedicated for continuation beyond the temporary turning circle.
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 416.011(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 (i.e., streets of less than full required right-of-way and pavement width) shall not be permitted except where such streets, when combined with a similar street (developed previously or simultaneously) on property adjacent to the subdivision, create or comprise a street that meets the right-of-way and pavement requirements of this Chapter.
G. 
Frontage Roads. Whenever a plat abuts or contains an existing or proposed major street, railroad 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.
H. 
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 Section, no temporary dead-end street in excess of one thousand (1,000) feet may be created unless no other practicable alternative is available.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
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 the City's Infrastructure Development Regulations and street grades shall conform as closely as practicable to the original topography.
B. 
In restricted or unusual conditions, it may not be practical to meet the design criteria set forth in the Infrastructure Development Regulations or other Sections of this Chapter. In such cases, every effort will be made to obtain the best possible design, alignment, grade, sight distance and drainage that are consistent with terrain, present and anticipated developments and safety. Safety shall always be the governing factor in any final engineering designs that deal with these limiting factors.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
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, pedestrian ways and/or easements through the interior of the block may be required by the Public Works Director. Such pedestrian ways shall have a minimum width of ten (10) feet.
4. 
In mixed-use ("MU") developments, the minimum block length will be no less than two hundred (200) feet and the maximum block length will not exceed one thousand (1,000) feet. The maximum block perimeter shall not exceed one thousand six hundred (1,600) feet in length.
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 which 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 which 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.
D. 
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.
E. 
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 governed by the requirements set forth in Section 416.039 of this Chapter.
F. 
Local streets shall intersect with surrounding collector or arterial streets at safe and convenient locations.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
Street rights-of-ways are designed and developed to serve several functions:
1. 
To carry motor vehicle traffic and in some cases allow on-street parking.
2. 
To provide safe and convenient passageway for bicycle and pedestrian traffic.
3. 
To serve as an important link in the City's drainage system.

D. 
Sidewalks shall be constructed along one (1) side of local and major 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.
E. 
Upon approval of a subdivision plat by the Board of Aldermen, all new streets, curbs, gutters, streetlights and sidewalks to be constructed within any new subdivision shall be completed in their entirety within the phase of development reflected on the plat of subdivision that was approved by the Board. No building permit or occupancy permit shall be issued for the construction or occupancy of a dwelling within the subdivision until said street, curbs, gutters, street lights and sidewalks have been completed as aforementioned.
F. 
In the event that climatic conditions would delay the completion of any new street, curbs, gutters or sidewalks, reasonable consideration shall be granted in accordance with the requirements set forth in Chapter 406 of this regulation.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
The minimum acceptable street design criteria and plan submittal requirements are set forth in the City's Infrastructure Development Regulations.
B. 
Detailed construction standards for streets, sidewalks and curbs and gutters shall be based on the requirements contained in the St. Robert Infrastructure Development Regulations.
C. 
Due consideration will be given to restrictive or unusual conditions that preclude the design of street infrastructure meeting the minimum standards delineated in the City Infrastructure Development Regulations. Design coordination with the City Engineer will be the basis for determining the best design alterative to overcome site restrictions and conditions. Safety will be the guiding factor.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
Curb ramps shall be constructed to accommodate wheelchair accessibility and shall be provided at all street intersections, designated pedestrian crossings and other major points of pedestrian flow. Curb ramps shall be constructed in accordance with the City's Infrastructure Development Regulations.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
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.

[Ord. No. 2118 §§1 — 3, 8-18-2008]
All developments shall provide a stormwater drainage system which is designed in conformance with the St. Robert Infrastructure Development Regulations.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
The developer shall be responsible for maintaining all improvements required by this regulation or any permit issued in accordance with its provisions, until such time as the infrastructure improvements have been accepted by the Board of Aldermen. As illustrations, and without limiting the generality of the foregoing, 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.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
The foregoing regulations regarding developments shall apply to all non-residential developments within the City of St. Robert.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
When the development of a lot, tract, parcel or subdivision require the construction of streets, drainage structures, water, sewer, street lights and sidewalks, the developer may be required to provide a form of surety to indemnify the City of St. Robert in accordance with Section 406.021 of this regulation.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
Approval of a preliminary subdivision plat does not constitute formal acceptance by the City of St. Robert the offer of dedication of any streets, sidewalks, sanitary sewers, domestic water, storm sewers, 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 final plat of subdivision to the Board of Aldermen for consideration with all dedicated areas having been constructed as depicted in the preliminary plat of subdivision approval.
C. 
An affidavit from a registered engineer in the State of Missouri must accompany the developer's final subdivision plat, which shall affirm that all public improvements have been constructed in accordance with the standards and specifications of the City and that all new streets have in fact been constructed within the platted right-of-way of the development. All required "as-built" drawings and electronic files will be submitted with the final plat.
D. 
A written recommendation from the Director of Public Works shall accompany the documentation and shall summarize the acceptability of the plans, construction methods, testing and inspections results that are required by this regulation.
E. 
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. The developer shall remain and held responsible for abatement of any and all defects of the dedicated areas for a period not to exceed twelve (12) months.
F. 
Upon acceptance of the final plat and offer of dedication therein platted, any surety indemnifying the construction of all infrastructure improvements may be released. A maintenance (warranty) bond indemnifying the City against any and all defects shall be filed with the City at this time.
[Ord. No. 2118 §§1 — 3, 8-18-2008]
A. 
In order to promote safe and reasonable access between public roadways and adjacent land; improve the convenience and ease of movement of travelers on public roads; and permit reasonable speeds and economy of travel while maintaining the capacity of the roadway, the location and design of access points shall be in accordance with the following access management regulations. These regulations shall apply to all existing, planned or proposed roadways within the jurisdiction of the City of St. Robert. New or proposed street roadways within the City not identified on the adopted roadway plan of the Comprehensive Plan shall interconnect with the existing roadway network in a uniform and efficient manner.
B. 
Access Classification Of Streets. The Planning and Zoning Commission shall assign to each roadway or portion thereof, within the planning jurisdiction of the City of St. Robert, an access classification based on a consideration of existing and projected traffic volumes, adopted local transportation plans and needs, the existing and/or projected character of lands adjoining the roadway, adopted local land use plans and zoning and the availability of reasonable access to those lands. These access classifications are defined as follows:
1. 
Arterial streets. These roadways are capable of providing medium to high speeds and traffic volumes over medium to long distances. Direct access to abutting land is subordinate to providing service to through traffic.
a. 
Private direct access to an arterial street shall be permitted only when the property in question has no other reasonable access to the public roadway network.
b. 
The design and location of allowable private access points must comply with all applicable Sections of this Chapter.
c. 
All private direct access points to arterial streets shall be designated as "temporary" and all requirements of Subsection (K) (Temporary Access Points) of this Section shall apply.
d. 
The following roadways are hereby designated as arterial roadways:
(1) 
Missouri Avenue from the connection to Route Y south to Ft. Leonard Wood.
(2) 
Route Y from the connection to Missouri Avenue north to the City limits.
(3) 
Route Z from Missouri Avenue intersection east to Highway 28.
(4) 
Old Route 66 from Missouri Avenue intersection west to City limits.
2. 
Collector streets. These streets are capable of providing moderate travel speeds and traffic volumes and generally provide the linkage between arterial and local streets. There is a reasonable balance between access and mobility needs within this classification.
a. 
Generally, only one (1) private access point shall be provided to an individual parcel from a local street unless it can be shown that additional access points would not be detrimental to the safety and operation of the roadway and are necessary for the approved use of the property.
b. 
The design and location of allowable access points must comply with all applicable Sections of this regulation.
c. 
The following roadways are hereby designated as collector streets:
(1) 
Eastlawn Avenue from Missouri Avenue intersection east to City limits.
(2) 
St. Robert Boulevard from Route Y intersection west to Old Route 66.
(3) 
North Outer Road from Route Y intersection east to Highway 28.
(4) 
Ziegenbein Road from Old Route 66 intersection north to City limits.
(5) 
Superior Road.
(6) 
Carson Boulevard.
(7) 
McKinnon Street.
3. 
Local streets. These streets allow for low to medium travel speeds and traffic volumes and are linked to the roadway network through intersections with arterial or collector streets and other local streets. Access needs take priority over through traffic movement without compromising the public health, welfare and safety.
a. 
The number of access points to a parcel is limited only to the requirements of Subsection (D) (Minimum Corner Clearance) and Subsection (E) (Minimum Sight Distance) of this Section.
b. 
All roadways or portions thereof as shown on the roadway plan of the Comprehensive Plan, not previously designated as arterial or collector streets, are hereby designated as local streets.
C. 
Minimum Spacing Of Driveways. In order to minimize the potential for accidents and delay to through vehicles, all adjacent driveways onto arterial and collector streets must be separated by the minimum distance measured from near edge to near edge of adjacent driveways as shown in Table 1 according to the posted speed limit on the roadway. Additionally, the spacing of adjacent driveways should be as uniform as possible between major intersections. Distances between adjacent one-way driveways with the inbound drive upstream from the outbound drive can be one-half (½) the distances shown on Table 1 providing that other requirements are satisfied.

F. 
Provisions For Maintaining The Capacity Of The Roadway. The Planning and Zoning Commission may require that upon completion of a development all traffic requiring access to and from the development shall operate in such a manner as to not adversely affect the capacity of the roadway. Provisions for the present or future construction of a frontage road, restriction or channelization of turning movements or other improvements may be required, as a condition of approval, in order to maintain the capacity of any adjacent roadway.
G. 
Number Of Access Points. Each existing tract of land is entitled to one (1) direct or indirect access point to the public roadway network provided that its location and design fulfill, as a minimum, the requirements of Subsection (D) (Minimum Corner Clearance) and Subsection (E) (Minimum Sight Distance) of this Section. Where the roadway frontage of a tract of land is greater than five hundred (500) feet, an additional access point may be allowed if determined by the City Engineer that the access point will not adversely affect the capacity of the roadway. Any additional access point must be in compliance with all applicable Sections of this regulation.
H. 
Coordination Of Access Points. Major access points on opposite sides of the arterial and collector streets shall be located opposite each other. If not so located, turning movement restrictions may be imposed as determined necessary by the Planning and Zoning Commission. In addition, in order to maximize the efficient utilization of access points, access drives shall be designed, located and constructed in a manner to provide and make possible the coordination of access with and between adjacent properties developed (present or future) for similar or compatible uses. As a condition of approval for construction, use or reuse of any access point, the Planning and Zoning Commission may require that unobstructed and unencumbered access, in accordance with the provisions of this Section, be provided from any such access point to adjacent properties.
I. 
Consolidation Of Existing Access Points. Whenever the use of a parcel of land changes, or two (2) or more parcels of land are assembled under one (1) purpose, plan, entity or usage, the existing driveway entrance points shall become void and the new driveway entrances shall be based upon the owner/developer's plans to use some existing driveways and/or close or relocate other driveways. Any such new or reauthorized access point must be in compliance with all applicable Sections of this regulation.
J. 
Design Of Access Points. The width, angle, grade, curb radii and other design aspects of driveway access points shall be in accordance with the Infrastructure Development Regulations of the City of St. Robert. (See Section 500.090.)
K. 
Temporary Access Points. Any access point that does not comply with one (1) or more paragraphs of this Section may be designated as "temporary" upon approval by the Planning and Zoning Commission. In all cases where said access points are classified as "temporary", such designation shall be duly noted on the plot plan or site plan submitted for approval and also upon the deed of the property in question. When a property served by a temporary access point is provided an alternative means of access, such as a connection to a frontage road, an intersecting street or a shared driveway, the Planning and Zoning Commission may require that the temporary access be eliminated, altered or limited to certain turning movements.
L. 
Spacing Restrictions For Signalized Access Points. Access points shall be designed such that those which will warrant signalization shall be spaced a minimum distance of one-quarter (¼) mile apart and one-quarter (¼) mile from the nearest signalized intersection. The location and design of the signalized access points shall be determined by a traffic engineering study prepared by a qualified traffic engineer at the developer's expense. This study shall be subject to the approval of the Planning and Zoning Commission and shall account for at least the following variables:
1. 
Traffic signal phasing as determined by analysis of projected turning movements;
2. 
Traffic signal cycle length as determined by analysis of projected traffic volumes;
3. 
Type of signal to be installed (actuated or pre-timed);
4. 
Relationship to adjacent signals (existing or proposed) for purposes of signal interconnection and coordination;
5. 
Roadway geometrics and sight distance considerations; and
6. 
Accident experience.
If the installation of a traffic signal is approved, the developer may be required to participate in the cost of design, purchase, installation, operation and maintenance of the signal equipment.
M. 
Provision Of Exclusive Turning Lanes And Deceleration/Acceleration Lanes. At those access points where vehicles turning to and from the roadway will affect the capacity of the roadway or create an unacceptable accident risk, the developer shall dedicate sufficient right-of-way and construct turning lanes or deceleration/acceleration lanes as necessary to maintain the capacity of the roadway and minimize the potential accident risk.
N. 
Provision Of Frontage Roads. The Planning and Zoning Commission may require the use of frontage roads to provide access to property adjacent to arterial streets or other collector streets as necessitated by the plan of development. The landowner/developer may be required to construct the frontage road to the side and/or rear property lines or reserve sufficient right-of-way to allow future construction. As adjacent property develops landowner/developers shall be required to interconnect the individual portions of frontage roads as appropriate. Access to the roadway via an intersecting street or a shared driveway may be required if the use of a frontage road is not feasible.
