3.
Self-imposed restrictions. If the owner places restrictions on any of the land contained in the subdivision greater than those required by this UDC, those restrictions or references to those restrictions shall be required to be indicated on the subdivision plat. Where restrictive covenants are less restrictive than those required by this UDC, the more restrictive regulation shall prevail. All restrictive covenants shall be filed in the office of the county clerk, which directly affects the land being subdivided.
4.
Character of the land. Land that the planning commission finds to be unsuitable for subdivision or development due to flooding, improper drainage, steep slopes, rock formations, adverse earth formations or topography, utility easements, or other features that will reasonably be harmful to the safety, health, and general welfare of the present or future inhabitants of the subdivision and/or its surrounding areas, shall not be subdivided or developed unless adequate methods are formulated by the developer and approved by the planning commission, upon recommendation of the city engineer, to solve the problems created by the unsuitable land conditions. That land shall be set aside for uses that shall not involve any danger to public health, safety, and welfare.
5.
Subdivision name. The proposed name of the subdivision shall not duplicate, or too closely approximate phonetically, the name of any other subdivision within the city or within Pottawatomie County's jurisdiction. The planning commission shall have final authority to designate the name of the subdivision, which shall be determined at time of plat approval.

7.
Street designation. The planning commission and city commission may consider changing existing public streets to private streets or private streets to public streets.
8.
Homeowner's association (HOA) and property owners association (POA). For any subdivision utilizing or incorporating private streets, shared parking, common drives, islands, or medians within street rights-of-way, and/or any other common areas, a homeowner's association (HOA) or property owners association (POA) shall be established and be responsible for maintenance of those easements and common areas.
9.
Plats straddling municipal boundaries. Whenever access to the subdivision is required across land in another local government, the planning commission may request assurance from the city attorney that access is legally established, and from the director that the access street is adequately improved, or that the applicant has fully executed a performance bond of sufficient quantity to assure the construction of the access street. Whenever possible, lot lines shall conform to municipal boundary lines.
B.
Public facilities and services.
1.
Adequate public facilities. No preliminary plat shall be approved unless the planning commission determines that public facilities will be adequate to support and service the area of the proposed subdivision. The applicant shall, at the request of the planning commission, submit sufficient information and data on the proposed subdivision to demonstrate the expected impact on, and use of, public facilities by possible uses of that subdivision. Public facilities and services to be examined for adequacy will include necessary street improvements, drainage, water service, sewerage, capital improvements, and other improvements.
2.
Extension policies. All public improvements and required easements shall be extended through the parcel on which new development is proposed. Roads, water lines, wastewater systems, drainage facilities, and other required public utilities shall be constructed through new development to promote the logical extension of public infrastructure. The city may require the applicant of a subdivision to extend offsite improvements to reach the subdivision or oversize required public facilities to serve anticipated future development as a condition of plat approval.
C.
Lot improvements.
1.
Generally. The size, shape, and orientation of lots must comply with applicable UDC regulations. When lots will not be served by centralized sewer or water service, lot dimensions and area must comply with the requirements of the Oklahoma Department of Environmental Quality.
2.
Lot arrangement. All lot types and arrangements shall comply with this UDC to provide access to buildings on those lots from an approved street, or from a private access drive approved under division 5, section 22-221.F.3., and to avoid any foreseeable natural or manufactured difficulties. See Figure V.1: Lot Types and Arrangements for the various lot types and arrangements.
Figure V-1: Lot Types and Arrangements
3.
Lot dimensions/sight triangle. Lot dimensions shall comply with the minimum standards of this UDC. Corner lot lines shall provide a sight distance triangle with legs of 25 feet from the point of intersection of the property lines along both property lines.
4.
Lot drainage. Lot layouts shall provide positive drainage away from all buildings, and individual lot drainage shall reflect the general storm drainage pattern for the area. Drainage design shall comply in all respects with the Engineering Design Manual.
5.
Through lots. Through lots shall be avoided except where necessary, as determined by the city engineer, to provide separation of residential development from traffic arterials or to overcome disadvantages of topography and orientation.
6.
Flag lots.
a.
Generally, flag lots shall not be created during the subdivision process.
b.
The creation of flag lots may be approved only if a flag lot design:
i.
Limits direct access onto an arterial street;
ii.
Provides greater protection of sensitive natural resources areas;
iii.
Hides or conceals utility buildings/substations, or radio, television, or telecommunication towers; or
iv.
Avoids substantial hardship to the subject property owner due to the property's topography or any other condition.
c.
Flag lot conditions may be imposed, including, but not limited to, requirements for shared driveways, maximum flag lot length, minimum street frontage, and minimum flag lot width.
7.
Reserve lots. These regulations recognize that it may occasionally be necessary and in the public interest to create lots designated as reserve areas to be occupied by stormwater detention, common recreation, private rights-of-way, or other similar uses. If declared reserved for those purposes by restrictive covenants or other recorded legal documents approved by the city or Pottawatomie County, reserve areas are exempt from this UDC's lot regulations.
8.
Proximity to railroads and limited access highways. When the area to be subdivided adjoins or contains a railroad right-of-way or limited access highway, lots that back onto that right-of-way shall have appropriate provisions for buffering and access control as required by division 4.
9.
Access.
a.
Every lot shall have frontage on, and access to, a public street or private road meeting right-of-way and improvement standards. Minimum frontage shall be established per division 2.
b.
Lots shall not, in general, derive access exclusively from a highway or major arterial street.
c.
Where driveway access from a highway or arterial street may be necessary for several adjoining lots, the planning commission may require that those lots be served by a combined access drive in order to limit possible traffic hazards on the road.
d.
If a property with frontage along a highway or arterial street is proposed to be subdivided or developed, the planning commission is authorized to restrict access to the respective street and require that a property owner take one or more of the following actions:
i.
Create through lots that back onto the highway or arterial street and front onto and take access from a parallel street, coupled with the installation of a fence, wall, or vegetative visual screen along the highway or major arterial street frontage;
ii.
Provide a frontage road separated from the highway or arterial street;
iii.
Establish deed restrictions or other legally enforceable means of preventing private driveway access to the highway or arterial street;
iv.
Provide a cross-access easement to abutting properties that front on the same highway or arterial street; or
v.
Provide a mutual, reciprocal, non-exclusive easement (mutual access easement) to ensure perpetual access to the subject property.
e.
Driveways shall be designed and arranged to avoid requiring vehicles to back into traffic on highways and arterial streets.
f.
For paving requirements in the right-of-way adjoining any city street, see the Engineering Design Manual.
10.
Access points. Access shall be provided to each subdivision in accordance with the Engineering Design Manual.
a.
Waivers to these access restrictions for subdivisions may be considered by the planning commission if the developer can prove that the property in question cannot comply due to the following conditions:
i.
Property frontage is too narrow; or
ii.
Site topography restrictions.
b.
The planning commission may consider a street stub into undeveloped property with an alternate emergency access easement as part of a subdivision proposal to warrant a waiver of the above access restrictions.
c.
When the first or subsequent phase(s) of a preliminary plat containing 100 or more lots is submitted, the access or entrance street must be designed in accordance with the criteria established in the Engineering Design Manual, if the phases do not connect to an alternate access point.
11.
Platted building lines. Platted building lines contained in an approved final plat that are more restrictive than the setback of the UDC, shall represent the legal setback lines.
D.
Streets.
1.
Generally.
a.
The arrangement, character, extent, width, grade, access to, and location of all streets shall conform to the city comprehensive plan's intent and are considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed land uses to be served by streets.
b.
No permit shall be issued for any development that does not access a street right-of-way compatible with the requirements of this section, or a private access easement that complies with the minimum width requirements.
c.
A traffic impact analysis study is required for:
i.
Any development proposal greater than 20 acres or any development proposal greater than five lots; and
ii.
Any nonresidential development proposal when the expected traffic generation is:
(A)
Greater than 2,000 vehicle trips per day (tpd).
(B)
Less than 2,000 tpd if the peak hour operation of the development is expected to generate more than 150 vehicle trips per hour (tph).
d.
Any required TIA shall meet the requirements and specifications established in the city's Engineering Design Manual.
e.
Roads shall be graded, improved, and conform to the standards and specifications established in the Engineering Design Manual as required by a grading and improvement plan.
f.
Pavement and utilities shall comply with the following provisions:
i.
Plans for pavement and utilities shall be prepared by a professional engineer and in accordance with the laws of the State of Oklahoma and the ordinances of the city.
ii.
The applicant shall file with the city a surety bond, and in the amount of 110 percent of the estimated construction cost, conditioned that the applicant, as principal, will faithfully install and complete improvements and utilities in the subdivision within a period not to exceed two years, according to the requirements of approved plans, subdivision rules and regulations, and municipal ordinances, regulations and specifications, and will pay all bills for contractors, improvements and utilities. This requirement only applies when infrastructure is not installed at the time of final plat/plan.
iii.
An extension of this period may be allowed by the city commission.
iv.
The professional engineer shall furnish the cost of pavement and utilities to the city engineer who shall approve the estimated costs of paving, storm sewers, and other drainage facilities, if required, in order that the planning commission may determine whether or not the amount of the bond submitted is adequate to ensure the construction of these facilities and to protect the interests of the city and public welfare.
v.
All current policies, inspection fees, and other normal requirements of the city shall apply in full force to ensure the proper construction of the private street.
vi.
In lieu of the provision contained in subsections i.—v. above, the applicant may submit a document prepared by a professional engineer that certifies that all private streets for the development are constructed to the city's standards. The plat or deed shall not be signed and released until certification is received and reviewed by the city.
2.
Street layout.
a.
Topography.
i.
Grades of streets shall conform as closely as possible to the original topography. If possible, all streets shall be arranged to provide building sites at, or above, the grade of the street; otherwise, adequate provisions for drainage must be made. A combination of steep grades and curves shall be avoided. Specific design standards are established in the Engineering Design Manual.
ii.
Collector and local streets shall be designed to conform as much as possible to the topography to:
(A)
Discourage use by through traffic;
(B)
Permit efficient drainage and utility systems; and
(C)
Require the minimum number of streets necessary for convenient and safe access to property.
b.
Integration of existing streets. All streets shall be properly integrated with the existing and proposed system of thoroughfares and dedicated rights-of-way and shall provide for the integration of future streets. If a subdivision abuts or contains an existing or proposed street, the planning commission may require:
i.
Marginal access streets;
ii.
Reverse frontage with screen planting contained in non-access reserve strips along the rear property line;
iii.
Deep lots with rear service alleys, or minimum distances between intersecting driveways and streets, or other treatment necessary for adequate protection of residential properties and to afford separation of through and local traffic;
iv.
Minimum spacing between intersecting driveways onto a street or arterial street to conform to the requirements in the Engineering Design Manual.
c.
Railroad right-of-way. If a subdivision borders on or contains a railroad right-of-way, the planning commission may require a buffer zone between the railroad right-of-way and the residential development to a distance of 300 feet minimum suitable for the appropriate use of the intervening land. These distances consider grade approaches and future grade separations.
d.
Permanently designed dead-end streets.
i.
Permanently designed dead-end streets shall not be longer than 500 feet or serve more than 20 dwelling units.
ii.
Permanently designed dead-end streets shall provide a turn-around at the closed end with an outside roadway diameter of at least 100 feet, and a street property line diameter of at least 120 feet.
iii.
The planning commission may approve a permanently design dead-end street that extends to 1,000 feet after reviewing and considering pedestrian connectivity.
e.
Temporary designed dead-end streets.
i.
Temporary turnarounds must be provided at the end of stub streets that are intended for extension when a subsequent phase of the development is completed or when the abutting property is developed if the stub street is more than 150 feet in length, as measured from the centerline of the intersecting street to the perimeter of the subdivision to which the stub street extends.
ii.
At the time that the temporary dead-end street is extended or connected to another street segment, any existing temporary turnaround must be removed by the property owner responsible for extending the street. If for any reason the stub street is not extended, a permanent turnaround must be constructed by the subject property owner on the abutting site being developed.
iii.
Stub streets must be clearly marked on plats and labeled "Future Street Extension." In addition, developers must post an approved sign in the right-of-way of the stub street indicating that the temporary dead-end street is intended as a "future street extension."
f.
Connections.
i.
The system of streets designated for the subdivision must connect with streets already dedicated in adjacent subdivisions.
ii.
Where adjacent connections are not platted, the general projection of streets in the nearest subdivided tracts must continue to the boundaries of the tract subdivided, so that other property owners may connect.
iii.
Preliminary plats shall be designed to provide interconnection between adjacent tracts, plats and/or parcels.
(A)
There shall be at least one street connecting each quarter section.
(B)
An adjoining subdivision may not tie into an existing stub street for its primary entrance unless landlocked.
(C)
A stub street shall not warrant a wider street than required because of traffic counts for the original tract.
(D)
A property owner shall, if a stub street is required, construct the stub street or grant an easement reserving the minimum right-of-way required for the stub street and any related utilities.
(E)
The property owner must build the return for the proposed stub with a connecting curb across the back and add a note to the plat that identifies this area as a street stub. These streets must be constructed in accordance with the city's adopted standards. All streets, including stub streets, and rights-of-way shall be dedicated to the city.
(F)
The length of the stub street shall not exceed the average length of residential lots in the subdivision or 150 feet, whichever is greater. Street stubs must be constructed simultaneously with the improvements within the final plat. Street stubs shall be constructed to the adjoining property line at time of initial development. The owner is responsible for all costs associated with the construction of that stub street and its associated utilities.
(G)
If a stub street is not required to be connected to the adjacent development on the final plat of that development, then that stub street may be closed and/or vacated as provided by law. The planning commission shall consider physical barriers, land use incompatibilities, proposed amenities that are under private property owners' control (pools, playgrounds, etc.), existing undeveloped landlocked properties, and any potential inappropriate traffic designs to justify a waiver of this requirement.
iv.
Reserve strips of land controlling access to or egress from other property from any street or alley or having the effect of restricting or damaging the adjoining property, are not permitted in any subdivision unless those reserve strips are conveyed to the city in fee simple.
g.
Widening and realignment of existing roads. Where a subdivision borders an existing road not constructed to the city's standards or when the comprehensive plan or udc regulations indicate plans for realignment or widening of a road that would require use of some of the land in the subdivision, the property owner shall dedicate the additional right-of-way from the centerline. Right-of-way shall be dedicated to accommodate full build-out of the designated street classification. Land reserved for any road purposes shall not be counted in satisfying yard or area requirements of the UDC. Land shall be either dedicated to the city in fee simple or as an easement.
3.
Street classification.
a.
Generally. The components of the city's street system are divided into six major classifications with corresponding right-of-way widths. All yards or setbacks abutting a shall be measured from the proposed right-of-way as shown on the city's adopted major street and highway plan and any adopted sidewalk and recreational trails master plan.
b.
Highway. A highway is a limited access, high speed roadway with grade separated interchanges. Highways are of regional significance and the interchanges may have a significant impact on land use due to their desirability as locations for commerce and industry. Highways are generally controlled by the State of Oklahoma with variable width right-of-way dimensions.
c.
Major arterial. A major arterial is a street type that provides for longer, direct trips on relatively straight paths that often connect to highways. This street type is generally controlled by the State of Oklahoma or the city.
d.
Minor arterial. A minor arterial is a street type typically found between major arterials that provides continuous paths to intermediate destinations and alternate routes for longer trips. This street type is generally controlled by the city.
e.
Non-industrial collector. A non-industrial collector is a street type typically found between minor arterials that provide frequent interconnections between neighborhoods. Non-industrial collectors allow local trips that mostly avoid the arterial network. This street type is generally controlled by the city.
f.
Industrial collector. An industrial collector is a collector street that primarily accommodates large vehicular traffic. This street type is generally controlled by the city.
g.
Local. A local street is a street type interconnected within neighborhoods that adjoin other neighborhoods. These streets discourage through traffic and are generally controlled by the city.
4.
Street design.
a.
Generally.
i.
Streets will follow the regulations, allocations, and required standards established in the city's Engineering Design Manual, including regulations for travel lanes, median/turning lanes, pedestrian facilities, and other elements.
ii.
To facilitate flexibility in design while maintaining the safety, health, and welfare of the public, the city engineer may grant administrative modifications to street design if:
(A)
The city engineer certifies that the proposed exception does not conflict with the goals and policies of the comprehensive plan; and
(B)
The applicant demonstrates, through documentation and/or studies, based on generally accepted engineering principles, that exceptions to the standard provided by this section would not pose a threat to health and safety.
iii.
Street and access easement designs shall conform with the latest American Association of State Highway and Transportation Officials publication of "A Policy on Geometric Design of Highways and Streets." A professional engineer registered in the State of Oklahoma shall prepare and sign street design plans. For intersection design purposes, local streets and non-industrial collectors assume passenger vehicles only, arterials (major and minor) will carry single-unit trucks and city transit buses, and all industrial collectors and highways will carry vehicles of WB-50.
iv.
The applicant shall install all utilities, shall construct curbs and gutters, and shall surface roadways to the widths prescribed in these regulations and the Engineering Design Manual. All road pavement, shoulders, drainage improvements and structures, curbs, turnarounds, and sidewalks shall conform to all construction standards and specifications adopted by the planning commission or city commission, this UDC, and Engineering Design Manual.
b.
Intersections.
i.
Intersections at right angles.
(A)
Streets shall intersect at right angles.
(B)
The city engineer may authorize intersection modifications as needed based on topography constraints or other restrictive site conditions.
(C)
An oblique street shall be curved approaching an intersection and shall connect at right angles.
(D)
No more than two streets shall intersect at any one point.
ii.
New intersections along existing streets.
(A)
Proposed new intersections along an existing street shall, wherever practical, coincide with an existing intersection on the opposite side of that street.
(B)
Centerline offsets of less than 150 feet shall not be permitted when intersecting an arterial street, except where the intersected street has separated dual drives without median breaks.
(C)
Centerline offsets of less than 110 feet shall not be permitted when intersecting local or collector streets.
(D)
Where any street intersects a street, its alignment shall be continuous.
(E)
The intersection of streets shall be separated in accordance with the access provisions of this section and the Engineering Design Manual.
iii.
Intersection grade. Intersections shall be designed with the specifications and requirements established in the Engineering Design Manual.
iv.
Intersection visibility. At any street intersection where earth banks or existing vegetation inside any lot corner create a traffic hazard by limiting visibility, the applicant shall cut that ground and/or vegetation (including trees) in connection with the grading of the public right-of-way to the extent deemed necessary to provide an adequate sight distance as established in the Engineering Design Manual.
c.
Driveway spacing. Driveways shall be separated from street intersections by the distance defined in the Engineering Design Manual.
d.
Excess right-of-way. Right-of-way widths in excess of the standards designated in these regulations shall be required whenever additional width is necessary, due to topography, to provide adequate earth slopes. Excess slopes shall be addressed and accommodated by the specifications and requirements established in the Engineering Design Manual or another construction method approved by the city engineer.
e.
Railroads and limited access highways. Railroad rights-of-way and limited access highways that are adjacent to subdivided lands shall be treated as follows:
i.
Generally. Streets parallel to the railroad when intersecting a street that crosses the railroad at grade shall, to the extent practical, be at a distance of at least 150 feet from the street centerline to the railroad right-of-way. Those distances shall be determined with due consideration to the minimum distance required for future separation of grades by means of appropriate approach gradients.
ii.
In residential districts.
(A)
A platted setback line of at least 20 feet in depth, in addition to the required setback, shall be provided adjacent to the railroad right-of-way or limited access highway.
(B)
A six-foot fence shall be erected on all residential lots abutting railroads and limited access highways.
iii.
In nonresidential districts. The nearest street extending parallel or approximately parallel to the railroad shall, wherever practical, be at a sufficient distance there from to ensure suitable lot depth.
f.
Street design criteria. All streets shall comply with the criteria established in the city's Engineering Design Manual.
g.
Streets not identified. For purposes of streets and easements not identified in the city's street system, the following applies:
i.
Streets shall have a 50-foot right-of-way with a 30-foot paving section.
ii.
Access easements intended for primary access to a proposed lot or building are 50 feet wide with a 30-foot paving section.
5.
Blocks and street lengths.
a.
Generally.
i.
Blocks shall have sufficient width to provide for two tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted in blocks for nonresidential development, or blocks adjacent to highways and major arterials, railroads or waterways; provided other applicable provisions of this section are met.
ii.
The lengths, depths, and shapes of blocks shall be appropriate for the locality and type of development contemplated.
(A)
Block lengths in residential areas along local streets shall not exceed 1,500 feet, except where lots side or back onto arterial streets.
(B)
Wherever practical, blocks along arterial streets shall not be less than 500 feet in length.
(C)
Block length shall be measured from property line to property line along the centerline of the block.
Figure V-2: Block Measurements
iii.
The planning commission may require the reservation of an easement through long blocks exceeding 1,000 feet in length to accommodate utilities, drainage facilities, or pedestrian traffic.
(A)
Pedestrian ways or crosswalks, not less than six feet in width, may be required by the planning commission through the center of a block, if deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation, or other community facilities.
(B)
Blocks designed for nonresidential development shall be of a length and width, as determined suitable by the planning commission, and conform to the UDC, and other applicable ordinances.
b.
Exception. The planning commission may approve block lengths that deviate from the typical range if needed to ensure the proper projection of existing major arterials and existing platted blocks.
c.
Street length.
i.
For a typical street segment, street length means the distance following the centerline of the intersecting centerlines of the improved roadway between traffic control devices or culs-de-sac that halt vehicular movement (see Figure V.2: Measuring Street Length). The city engineer may approve a different street length than required by this subsection in industrial districts if the modified street lengths are needed to accommodate safe and efficient truck movements and do not cause a violation of the city's most recently adopted International Fire Code.
Figure V-3: Measuring Street Length
ii.
An L-shaped (elbow type) intersection is an intersection formed by the roadway centerlines of two different non-continuous street lengths where the interior angle formed by these intersecting street lengths is at least 72 degrees and no greater than 120 degrees (See Figure V-4: L-shaped (elbow type) Intersection). Each leg of an L-shaped (elbow type) intersection is considered a separate street section in determining street length.
Figure V-4: L-shaped (elbow type) Intersection
iii.
Street segment. A street segment means the section of the street length that results from the placement of traffic calming devices (See Figure V-3: Traffic Calming Devices).
Figure V-5: Traffic Calming Devices
iv.
Maximum continuous street length.
(A)
No continuous street length shall exceed the requirements established in Table V.1: Maximum Street Length unless the following requirements are met.
Table V.1: Maximum Street Length
(B)
A street length may extend if:
(1)
An approved traffic calming device(s) as described in Division 5, section 22-221.D.6.b.ii. and Table V.2: Street Length and Traffic Calming;
(2)
The street intersects an arterial roadway; or
(3)
The street serves as an entrance street to the proposed neighborhood; or
(4)
The street provides an opportunity for traffic to pass from a street of a higher classification to another street link; or
(5)
The street width is at least 40 feet.
v.
School street length. For a new school development, all collector and local streets fronting the school require the placement of approved traffic calming devices, including signs and striping maintaining a street segment length of 200 to 400 feet.
d.
Waivers.
i.
The planning commission may waive block lengths and street lengths if the waiver is requested in writing and incorporates traffic impact mitigation measures into a site plan. This waiver is submitted in conjunction with a preliminary plat/replat application.
ii.
The planning commission may not grant a block length waiver unless traffic impact mitigation measures comply with standards (adopted here as minimum standards) of the latest version of the Institute of Transportation Engineers Manual of Transportation Engineering Studies.
iii.
A block length waiver shall not modify the proper extension of any street.
iv.
A block length waiver shall not compromise safety.

Traffic calming.
a.
Purpose. Long streets, wide street cross sections, and uninterrupted traffic flows can encourage speeding on local streets. Traffic calming is a combination of physical measures that reduce the negative effects of motor vehicle use, alter driver behavior, and improve conditions for non-motorized street users. Traffic calming and street design standards slow traffic while allowing flexibility and design and offering applicants the choice of treatment that works best for the streets in a proposed development. Traffic control devices, notably stop signs and speed limits, are regulatory measures that require enforcement. Traffic calming measures are self-enforcing.
b.
Streets, street length, and traffic calming.
i.
Different street types and varying street lengths require traffic calming devices to help reduce travel speeds, improve safety, and promote walkability.
ii.
If the street segment criteria in division 5, section 22-221.D.5.c.iv. are surpassed, the applicant shall install a traffic calming device(s) including signs and striping, designed, and approved by the city. The applicant shall follow the standards prescribed in Table V.2: Street Length and Traffic Calming. This table allocates traffic calming devices according to different street types and their varying street lengths.
Table V.2: Street Length and Traffic Calming
c.
L-shaped (elbow type) intersections.
i.
These intersections require a traffic calming device if the street length to the center of the intersection, measured from the point where the projection of the center lines for the two street sections intersect, exceeds 600 feet.
ii.
Each leg of an L-shaped (elbow type) intersection is considered a separate street section.
iii.
When required, the traffic calming device(s) must maintain a maximum of 400 feet from the center of the L-shaped (elbow type) intersection.
iv.
Any proposed street section that includes an L-shaped intersection is measured beginning at the center of the intersection.
v.
L-shaped intersections with interior angles less than 72 degrees are not permitted.
vi.
Intersections with interior angles greater than 120 degrees are not considered an L-shape (elbow type).
vii.
Where the interior angle exceeds 120 degrees, a smooth curved roadway design with a minimum radius conforming to the standards for the particular geometric section are used.
viii.
Where two L-shaped (elbow type) intersections are used to determine the street length, street length shall not exceed 1,000 feet.
ix.
A longer street length may be allowed through the placement of an approved traffic calming device(s) at distances described in division 5, section 22-221.D.6.b.ii. and Table V.2: Street Length and Traffic Calming.
d.
Raised platform. If traffic calming is necessary on a roadway adjacent to a school, a raised platform will be used as a crosswalk.

A.
Purpose. Performance guarantee and security requirements are established to address those circumstances under which an applicant wishes to receive final plat approval and record the approved final plat before installing required infrastructure and public improvements. The provisions help ensure that funding is in place to cover the cost of installing any required improvements that are not installed by the applicant within a reasonable period of time after receiving final plat approval.
B.
Term of agreement. The term of a performance guarantee shall not exceed two years. If the applicant has not completed the required infrastructure and public improvements within the two-year period, the director is authorized to approve one extension of up to six months in duration. Any additional extensions or extensions of a longer duration require approval of the planning commission. Approval authorities/decision-making bodies are authorized to require updated improvement cost estimates and additional security as a condition of any extension granted.
C.
Form and amount of security.
1.
Security must be in the form of an irrevocable letter of credit, cash, or another instrument readily convertible to cash, as approved by the city attorney or district attorney. The performance guarantee and security must be conditioned upon the performance of all work necessary to complete the required infrastructure and improvements.
2.
The estimated total cost of any required infrastructure and improvements that have not been installed by the applicant prior to recording of the approved final plat must be itemized by improvement type and certified by the applicant's registered engineer. Cost estimates must be based on industry norms within Shawnee.
3.
The amount of the performance guarantee must equal at least 110 percent of the estimated total cost of all required infrastructure and improvements that have not been installed by the applicant prior to recording of the approved final plat.
D.
Default and use of security. If the applicant fails to properly install required infrastructure and improvements within the term of the guarantee and any approved extension, the guarantee will be deemed in default. In the case of default, the city is authorized to draw or foreclose upon the security funds to fund completion of the required infrastructure and improvements or to contract for installation of the required infrastructure and improvements. If the cost of completing the required infrastructure and improvements exceeds the security amount, the applicant is liable for all excess costs. Any security funds to be drawn upon or foreclosed will be subject to an administrative fee that reflects the city's actual costs associated with preparing bid documents and preparing and administering a contract for the work to be completed.
E.
Release of security. The security must be released once all the following occur:
1.
The conditions of the performance guarantee have been completed to the satisfaction of all agencies with jurisdiction over the improvements;
2.

This obligation must be provided for in the plat, or for developments not required to be platted, by a deed restriction or other appropriate document recorded with the county clerk.
b.
If multiple property owners will be responsible for perpetual maintenance and control of common areas and public or private improvements, a property owners association must be established. Each property owner, by acceptance of a deed to a property within the development, will be deemed to have agreed to be a member of the property owner's association and be subject to assessment for maintenance of the common areas and public or private improvements.
c.
If the entire development is to remain under single ownership, the common areas and public or private improvements must be maintained by the owner of the property.
2.
Declarations and covenants.
a.
Declarations and covenants guaranteeing ongoing maintenance of common areas and public or private improvements must be established within a deed of dedication accompanying a plat or, for developments subject to these regulations but not required to be platted, by a deed restriction or other appropriate document recorded with the county clerk.

For any subdivision utilizing or incorporating private streets, shared parking, common drives, islands, or medians within street rights-of-way, and/or any other common areas, a homeowner's association (HOA) or property owners association (POA) shall be established and be responsible for maintenance of those easements and common areas.
9.
Plats straddling municipal boundaries. Whenever access to the subdivision is required across land in another local government, the planning commission may request assurance from the city attorney that access is legally established, and from the director that the access street is adequately improved, or that the applicant has fully executed a performance bond of sufficient quantity to assure the construction of the access street. Whenever possible, lot lines shall conform to municipal boundary lines.
B.
Public facilities and services.
1.
Adequate public facilities. No preliminary plat shall be approved unless the planning commission determines that public facilities will be adequate to support and service the area of the proposed subdivision. The applicant shall, at the request of the planning commission, submit sufficient information and data on the proposed subdivision to demonstrate the expected impact on, and use of, public facilities by possible uses of that subdivision. Public facilities and services to be examined for adequacy will include necessary street improvements, drainage, water service, sewerage, capital improvements, and other improvements.
2.
Extension policies. All public improvements and required easements shall be extended through the parcel on which new development is proposed. Roads, water lines, wastewater systems, drainage facilities, and other required public utilities shall be constructed through new development to promote the logical extension of public infrastructure. The city may require the applicant of a subdivision to extend offsite improvements to reach the subdivision or oversize required public facilities to serve anticipated future development as a condition of plat approval.
C.
Lot improvements.
1.
Generally. The size, shape, and orientation of lots must comply with applicable UDC regulations. When lots will not be served by centralized sewer or water service, lot dimensions and area must comply with the requirements of the Oklahoma Department of Environmental Quality.
2.
Lot arrangement. All lot types and arrangements shall comply with this UDC to provide access to buildings on those lots from an approved street, or from a private access drive approved under division 5, section 22-221.F.3., and to avoid any foreseeable natural or manufactured difficulties. See Figure V.1: Lot Types and Arrangements for the various lot types and arrangements.
Figure V-1: Lot Types and Arrangements
3.
Lot dimensions/sight triangle. Lot dimensions shall comply with the minimum standards of this UDC. Corner lot lines shall provide a sight distance triangle with legs of 25 feet from the point of intersection of the property lines along both property lines.
4.
Lot drainage. Lot layouts shall provide positive drainage away from all buildings, and individual lot drainage shall reflect the general storm drainage pattern for the area. Drainage design shall comply in all respects with the Engineering Design Manual.
5.
Through lots. Through lots shall be avoided except where necessary, as determined by the city engineer, to provide separation of residential development from traffic arterials or to overcome disadvantages of topography and orientation.
6.
Flag lots.
a.
Generally, flag lots shall not be created during the subdivision process.
b.
The creation of flag lots may be approved only if a flag lot design:
i.
Limits direct access onto an arterial street;
ii.
Provides greater protection of sensitive natural resources areas;
iii.
Hides or conceals utility buildings/substations, or radio, television, or telecommunication towers; or
iv.
Avoids substantial hardship to the subject property owner due to the property's topography or any other condition.
c.
Flag lot conditions may be imposed, including, but not limited to, requirements for shared driveways, maximum flag lot length, minimum street frontage, and minimum flag lot width.
7.
Reserve lots. These regulations recognize that it may occasionally be necessary and in the public interest to create lots designated as reserve areas to be occupied by stormwater detention, common recreation, private rights-of-way, or other similar uses. If declared reserved for those purposes by restrictive covenants or other recorded legal documents approved by the city or Pottawatomie County, reserve areas are exempt from this UDC's lot regulations.
8.
Proximity to railroads and limited access highways. When the area to be subdivided adjoins or contains a railroad right-of-way or limited access highway, lots that back onto that right-of-way shall have appropriate provisions for buffering and access control as required by division 4.
9.
Access.
a.
Every lot shall have frontage on, and access to, a public street or private road meeting right-of-way and improvement standards. Minimum frontage shall be established per division 2.
b.
Lots shall not, in general, derive access exclusively from a highway or major arterial street.
c.
Where driveway access from a highway or arterial street may be necessary for several adjoining lots, the planning commission may require that those lots be served by a combined access drive in order to limit possible traffic hazards on the road.
d.
If a property with frontage along a highway or arterial street is proposed to be subdivided or developed, the planning commission is authorized to restrict access to the respective street and require that a property owner take one or more of the following actions:
i.
Create through lots that back onto the highway or arterial street and front onto and take access from a parallel street, coupled with the installation of a fence, wall, or vegetative visual screen along the highway or major arterial street frontage;
ii.
Provide a frontage road separated from the highway or arterial street;
iii.
Establish deed restrictions or other legally enforceable means of preventing private driveway access to the highway or arterial street;
iv.
Provide a cross-access easement to abutting properties that front on the same highway or arterial street; or
v.
Provide a mutual, reciprocal, non-exclusive easement (mutual access easement) to ensure perpetual access to the subject property.
e.
Driveways shall be designed and arranged to avoid requiring vehicles to back into traffic on highways and arterial streets.
f.
For paving requirements in the right-of-way adjoining any city street, see the Engineering Design Manual.
10.
Access points. Access shall be provided to each subdivision in accordance with the Engineering Design Manual.
a.
Waivers to these access restrictions for subdivisions may be considered by the planning commission if the developer can prove that the property in question cannot comply due to the following conditions:
i.
Property frontage is too narrow; or
ii.
Site topography restrictions.
b.
The planning commission may consider a street stub into undeveloped property with an alternate emergency access easement as part of a subdivision proposal to warrant a waiver of the above access restrictions.
c.
When the first or subsequent phase(s) of a preliminary plat containing 100 or more lots is submitted, the access or entrance street must be designed in accordance with the criteria established in the Engineering Design Manual, if the phases do not connect to an alternate access point.
11.
Platted building lines. Platted building lines contained in an approved final plat that are more restrictive than the setback of the UDC, shall represent the legal setback lines.
D.
Streets.
1.
Generally.
a.
The arrangement, character, extent, width, grade, access to, and location of all streets shall conform to the city comprehensive plan's intent and are considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed land uses to be served by streets.
b.
No permit shall be issued for any development that does not access a street right-of-way compatible with the requirements of this section, or a private access easement that complies with the minimum width requirements.
c.
A traffic impact analysis study is required for:
i.
Any development proposal greater than 20 acres or any development proposal greater than five lots; and
ii.
Any nonresidential development proposal when the expected traffic generation is:
(A)
Greater than 2,000 vehicle trips per day (tpd).
(B)
Less than 2,000 tpd if the peak hour operation of the development is expected to generate more than 150 vehicle trips per hour (tph).

i.
Plans for pavement and utilities shall be prepared by a professional engineer and in accordance with the laws of the State of Oklahoma and the ordinances of the city.
ii.
The applicant shall file with the city a surety bond, and in the amount of 110 percent of the estimated construction cost, conditioned that the applicant, as principal, will faithfully install and complete improvements and utilities in the subdivision within a period not to exceed two years, according to the requirements of approved plans, subdivision rules and regulations, and municipal ordinances, regulations and specifications, and will pay all bills for contractors, improvements and utilities. This requirement only applies when infrastructure is not installed at the time of final plat/plan.
iii.
An extension of this period may be allowed by the city commission.
iv.
The professional engineer shall furnish the cost of pavement and utilities to the city engineer who shall approve the estimated costs of paving, storm sewers, and other drainage facilities, if required, in order that the planning commission may determine whether or not the amount of the bond submitted is adequate to ensure the construction of these facilities and to protect the interests of the city and public welfare.
v.
All current policies, inspection fees, and other normal requirements of the city shall apply in full force to ensure the proper construction of the private street.
vi.
In lieu of the provision contained in subsections i.—v. above, the applicant may submit a document prepared by a professional engineer that certifies that all private streets for the development are constructed to the city's standards. The plat or deed shall not be signed and released until certification is received and reviewed by the city.
2.
Street layout.
a.
Topography.
i.
Grades of streets shall conform as closely as possible to the original topography. If possible, all streets shall be arranged to provide building sites at, or above, the grade of the street; otherwise, adequate provisions for drainage must be made. A combination of steep grades and curves shall be avoided. Specific design standards are established in the Engineering Design Manual.
ii.
Collector and local streets shall be designed to conform as much as possible to the topography to:
(A)
Discourage use by through traffic;
(B)
Permit efficient drainage and utility systems; and
(C)
Require the minimum number of streets necessary for convenient and safe access to property.
b.
Integration of existing streets. All streets shall be properly integrated with the existing and proposed system of thoroughfares and dedicated rights-of-way and shall provide for the integration of future streets. If a subdivision abuts or contains an existing or proposed street, the planning commission may require:
i.
Marginal access streets;
ii.
Reverse frontage with screen planting contained in non-access reserve strips along the rear property line;
iii.
Deep lots with rear service alleys, or minimum distances between intersecting driveways and streets, or other treatment necessary for adequate protection of residential properties and to afford separation of through and local traffic;
iv.
Minimum spacing between intersecting driveways onto a street or arterial street to conform to the requirements in the Engineering Design Manual.
c.
Railroad right-of-way. If a subdivision borders on or contains a railroad right-of-way, the planning commission may require a buffer zone between the railroad right-of-way and the residential development to a distance of 300 feet minimum suitable for the appropriate use of the intervening land. These distances consider grade approaches and future grade separations.
d.
Permanently designed dead-end streets.
i.
Permanently designed dead-end streets shall not be longer than 500 feet or serve more than 20 dwelling units.
ii.
Permanently designed dead-end streets shall provide a turn-around at the closed end with an outside roadway diameter of at least 100 feet, and a street property line diameter of at least 120 feet.
iii.
The planning commission may approve a permanently design dead-end street that extends to 1,000 feet after reviewing and considering pedestrian connectivity.
e.
Temporary designed dead-end streets.
i.
Temporary turnarounds must be provided at the end of stub streets that are intended for extension when a subsequent phase of the development is completed or when the abutting property is developed if the stub street is more than 150 feet in length, as measured from the centerline of the intersecting street to the perimeter of the subdivision to which the stub street extends.
ii.
At the time that the temporary dead-end street is extended or connected to another street segment, any existing temporary turnaround must be removed by the property owner responsible for extending the street. If for any reason the stub street is not extended, a permanent turnaround must be constructed by the subject property owner on the abutting site being developed.
iii.
Stub streets must be clearly marked on plats and labeled "Future Street Extension." In addition, developers must post an approved sign in the right-of-way of the stub street indicating that the temporary dead-end street is intended as a "future street extension."
f.
Connections.
i.
The system of streets designated for the subdivision must connect with streets already dedicated in adjacent subdivisions.
ii.
Where adjacent connections are not platted, the general projection of streets in the nearest subdivided tracts must continue to the boundaries of the tract subdivided, so that other property owners may connect.
iii.
Preliminary plats shall be designed to provide interconnection between adjacent tracts, plats and/or parcels.
(A)
There shall be at least one street connecting each quarter section.
(B)
An adjoining subdivision may not tie into an existing stub street for its primary entrance unless landlocked.
(C)
A stub street shall not warrant a wider street than required because of traffic counts for the original tract.
(D)
A property owner shall, if a stub street is required, construct the stub street or grant an easement reserving the minimum right-of-way required for the stub street and any related utilities.
(E)
The property owner must build the return for the proposed stub with a connecting curb across the back and add a note to the plat that identifies this area as a street stub. These streets must be constructed in accordance with the city's adopted standards. All streets, including stub streets, and rights-of-way shall be dedicated to the city.
(F)
The length of the stub street shall not exceed the average length of residential lots in the subdivision or 150 feet, whichever is greater. Street stubs must be constructed simultaneously with the improvements within the final plat. Street stubs shall be constructed to the adjoining property line at time of initial development. The owner is responsible for all costs associated with the construction of that stub street and its associated utilities.
(G)
If a stub street is not required to be connected to the adjacent development on the final plat of that development, then that stub street may be closed and/or vacated as provided by law. The planning commission shall consider physical barriers, land use incompatibilities, proposed amenities that are under private property owners' control (pools, playgrounds, etc.), existing undeveloped landlocked properties, and any potential inappropriate traffic designs to justify a waiver of this requirement.
iv.
Reserve strips of land controlling access to or egress from other property from any street or alley or having the effect of restricting or damaging the adjoining property, are not permitted in any subdivision unless those reserve strips are conveyed to the city in fee simple.
g.
Widening and realignment of existing roads. Where a subdivision borders an existing road not constructed to the city's standards or when the comprehensive plan or udc regulations indicate plans for realignment or widening of a road that would require use of some of the land in the subdivision, the property owner shall dedicate the additional right-of-way from the centerline. Right-of-way shall be dedicated to accommodate full build-out of the designated street classification. Land reserved for any road purposes shall not be counted in satisfying yard or area requirements of the UDC. Land shall be either dedicated to the city in fee simple or as an easement.
3.
Street classification.
a.
Generally. The components of the city's street system are divided into six major classifications with corresponding right-of-way widths. All yards or setbacks abutting a shall be measured from the proposed right-of-way as shown on the city's adopted major street and highway plan and any adopted sidewalk and recreational trails master plan.
b.
Highway. A highway is a limited access, high speed roadway with grade separated interchanges. Highways are of regional significance and the interchanges may have a significant impact on land use due to their desirability as locations for commerce and industry. Highways are generally controlled by the State of Oklahoma with variable width right-of-way dimensions.
c.
Major arterial. A major arterial is a street type that provides for longer, direct trips on relatively straight paths that often connect to highways. This street type is generally controlled by the State of Oklahoma or the city.
d.
Minor arterial. A minor arterial is a street type typically found between major arterials that provides continuous paths to intermediate destinations and alternate routes for longer trips. This street type is generally controlled by the city.
e.
Non-industrial collector. A non-industrial collector is a street type typically found between minor arterials that provide frequent interconnections between neighborhoods. Non-industrial collectors allow local trips that mostly avoid the arterial network. This street type is generally controlled by the city.
f.
Industrial collector. An industrial collector is a collector street that primarily accommodates large vehicular traffic. This street type is generally controlled by the city.
g.
Local. A local street is a street type interconnected within neighborhoods that adjoin other neighborhoods. These streets discourage through traffic and are generally controlled by the city.
4.
Street design.
a.
Generally.
i.
Streets will follow the regulations, allocations, and required standards established in the city's Engineering Design Manual, including regulations for travel lanes, median/turning lanes, pedestrian facilities, and other elements.
ii.
To facilitate flexibility in design while maintaining the safety, health, and welfare of the public, the city engineer may grant administrative modifications to street design if:
(A)
The city engineer certifies that the proposed exception does not conflict with the goals and policies of the comprehensive plan; and
(B)
The applicant demonstrates, through documentation and/or studies, based on generally accepted engineering principles, that exceptions to the standard provided by this section would not pose a threat to health and safety.
iii.
Street and access easement designs shall conform with the latest American Association of State Highway and Transportation Officials publication of "A Policy on Geometric Design of Highways and Streets." A professional engineer registered in the State of Oklahoma shall prepare and sign street design plans. For intersection design purposes, local streets and non-industrial collectors assume passenger vehicles only, arterials (major and minor) will carry single-unit trucks and city transit buses, and all industrial collectors and highways will carry vehicles of WB-50.
iv.
The applicant shall install all utilities, shall construct curbs and gutters, and shall surface roadways to the widths prescribed in these regulations and the Engineering Design Manual. All road pavement, shoulders, drainage improvements and structures, curbs, turnarounds, and sidewalks shall conform to all construction standards and specifications adopted by the planning commission or city commission, this UDC, and Engineering Design Manual.
b.
Intersections.
i.
Intersections at right angles.
(A)
Streets shall intersect at right angles.
(B)
The city engineer may authorize intersection modifications as needed based on topography constraints or other restrictive site conditions.
(C)
An oblique street shall be curved approaching an intersection and shall connect at right angles.
(D)
No more than two streets shall intersect at any one point.
ii.
New intersections along existing streets.
(A)
Proposed new intersections along an existing street shall, wherever practical, coincide with an existing intersection on the opposite side of that street.
(B)
Centerline offsets of less than 150 feet shall not be permitted when intersecting an arterial street, except where the intersected street has separated dual drives without median breaks.
(C)
Centerline offsets of less than 110 feet shall not be permitted when intersecting local or collector streets.
(D)
Where any street intersects a street, its alignment shall be continuous.
(E)
The intersection of streets shall be separated in accordance with the access provisions of this section and the Engineering Design Manual.
iii.
Intersection grade. Intersections shall be designed with the specifications and requirements established in the Engineering Design Manual.
iv.
Intersection visibility. At any street intersection where earth banks or existing vegetation inside any lot corner create a traffic hazard by limiting visibility, the applicant shall cut that ground and/or vegetation (including trees) in connection with the grading of the public right-of-way to the extent deemed necessary to provide an adequate sight distance as established in the Engineering Design Manual.
c.
Driveway spacing. Driveways shall be separated from street intersections by the distance defined in the Engineering Design Manual.
d.
Excess right-of-way. Right-of-way widths in excess of the standards designated in these regulations shall be required whenever additional width is necessary, due to topography, to provide adequate earth slopes. Excess slopes shall be addressed and accommodated by the specifications and requirements established in the Engineering Design Manual or another construction method approved by the city engineer.
e.
Railroads and limited access highways. Railroad rights-of-way and limited access highways that are adjacent to subdivided lands shall be treated as follows:
i.
Generally. Streets parallel to the railroad when intersecting a street that crosses the railroad at grade shall, to the extent practical, be at a distance of at least 150 feet from the street centerline to the railroad right-of-way. Those distances shall be determined with due consideration to the minimum distance required for future separation of grades by means of appropriate approach gradients.
ii.
In residential districts.
(A)
A platted setback line of at least 20 feet in depth, in addition to the required setback, shall be provided adjacent to the railroad right-of-way or limited access highway.
(B)
A six-foot fence shall be erected on all residential lots abutting railroads and limited access highways.
iii.
In nonresidential districts. The nearest street extending parallel or approximately parallel to the railroad shall, wherever practical, be at a sufficient distance there from to ensure suitable lot depth.
f.
Street design criteria. All streets shall comply with the criteria established in the city's Engineering Design Manual.
g.
Streets not identified. For purposes of streets and easements not identified in the city's street system, the following applies:
i.
Streets shall have a 50-foot right-of-way with a 30-foot paving section.
ii.
Access easements intended for primary access to a proposed lot or building are 50 feet wide with a 30-foot paving section.
5.
Blocks and street lengths.
a.
Generally.
i.
Blocks shall have sufficient width to provide for two tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted in blocks for nonresidential development, or blocks adjacent to highways and major arterials, railroads or waterways; provided other applicable provisions of this section are met.
ii.
The lengths, depths, and shapes of blocks shall be appropriate for the locality and type of development contemplated.
(A)
Block lengths in residential areas along local streets shall not exceed 1,500 feet, except where lots side or back onto arterial streets.
(B)
Wherever practical, blocks along arterial streets shall not be less than 500 feet in length.
(C)
Block length shall be measured from property line to property line along the centerline of the block.
Figure V-2: Block Measurements
iii.
The planning commission may require the reservation of an easement through long blocks exceeding 1,000 feet in length to accommodate utilities, drainage facilities, or pedestrian traffic.
(A)
Pedestrian ways or crosswalks, not less than six feet in width, may be required by the planning commission through the center of a block, if deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation, or other community facilities.
(B)
Blocks designed for nonresidential development shall be of a length and width, as determined suitable by the planning commission, and conform to the UDC, and other applicable ordinances.
b.
Exception. The planning commission may approve block lengths that deviate from the typical range if needed to ensure the proper projection of existing major arterials and existing platted blocks.
c.
Street length.
i.
For a typical street segment, street length means the distance following the centerline of the intersecting centerlines of the improved roadway between traffic control devices or culs-de-sac that halt vehicular movement (see Figure V.2: Measuring Street Length). The city engineer may approve a different street length than required by this subsection in industrial districts if the modified street lengths are needed to accommodate safe and efficient truck movements and do not cause a violation of the city's most recently adopted International Fire Code.
Figure V-3: Measuring Street Length
ii.
An L-shaped (elbow type) intersection is an intersection formed by the roadway centerlines of two different non-continuous street lengths where the interior angle formed by these intersecting street lengths is at least 72 degrees and no greater than 120 degrees (See Figure V-4: L-shaped (elbow type) Intersection). Each leg of an L-shaped (elbow type) intersection is considered a separate street section in determining street length.
Figure V-4: L-shaped (elbow type) Intersection
iii.
Street segment. A street segment means the section of the street length that results from the placement of traffic calming devices (See Figure V-3: Traffic Calming Devices).
Figure V-5: Traffic Calming Devices
iv.
Maximum continuous street length.
(A)
No continuous street length shall exceed the requirements established in Table V.1: Maximum Street Length unless the following requirements are met.
Table V.1: Maximum Street Length
(B)
A street length may extend if:
(1)
An approved traffic calming device(s) as described in Division 5, section 22-221.D.6.b.ii. and Table V.2: Street Length and Traffic Calming;
(2)
The street intersects an arterial roadway; or
(3)
The street serves as an entrance street to the proposed neighborhood; or
(4)
The street provides an opportunity for traffic to pass from a street of a higher classification to another street link; or
(5)
The street width is at least 40 feet.
v.
School street length. For a new school development, all collector and local streets fronting the school require the placement of approved traffic calming devices, including signs and striping maintaining a street segment length of 200 to 400 feet.
d.
Waivers.
i.
The planning commission may waive block lengths and street lengths if the waiver is requested in writing and incorporates traffic impact mitigation measures into a site plan. This waiver is submitted in conjunction with a preliminary plat/replat application.
ii.
The planning commission may not grant a block length waiver unless traffic impact mitigation measures comply with standards (adopted here as minimum standards) of the latest version of the Institute of Transportation Engineers Manual of Transportation Engineering Studies.
iii.
A block length waiver shall not modify the proper extension of any street.
iv.
A block length waiver shall not compromise safety.
6.
Traffic calming.
a.
Purpose. Long streets, wide street cross sections, and uninterrupted traffic flows can encourage speeding on local streets. Traffic calming is a combination of physical measures that reduce the negative effects of motor vehicle use, alter driver behavior, and improve conditions for non-motorized street users. Traffic calming and street design standards slow traffic while allowing flexibility and design and offering applicants the choice of treatment that works best for the streets in a proposed development. Traffic control devices, notably stop signs and speed limits, are regulatory measures that require enforcement. Traffic calming measures are self-enforcing.
b.
Streets, street length, and traffic calming.
i.
Different street types and varying street lengths require traffic calming devices to help reduce travel speeds, improve safety, and promote walkability.
ii.
If the street segment criteria in division 5, section 22-221.D.5.c.iv. are surpassed, the applicant shall install a traffic calming device(s) including signs and striping, designed, and approved by the city. The applicant shall follow the standards prescribed in Table V.2: Street Length and Traffic Calming. This table allocates traffic calming devices according to different street types and their varying street lengths.
Table V.2: Street Length and Traffic Calming
c.
L-shaped (elbow type) intersections.
i.
These intersections require a traffic calming device if the street length to the center of the intersection, measured from the point where the projection of the center lines for the two street sections intersect, exceeds 600 feet.
ii.
Each leg of an L-shaped (elbow type) intersection is considered a separate street section.
iii.
When required, the traffic calming device(s) must maintain a maximum of 400 feet from the center of the L-shaped (elbow type) intersection.
iv.
Any proposed street section that includes an L-shaped intersection is measured beginning at the center of the intersection.
v.
L-shaped intersections with interior angles less than 72 degrees are not permitted.
vi.
Intersections with interior angles greater than 120 degrees are not considered an L-shape (elbow type).
vii.
Where the interior angle exceeds 120 degrees, a smooth curved roadway design with a minimum radius conforming to the standards for the particular geometric section are used.
viii.
Where two L-shaped (elbow type) intersections are used to determine the street length, street length shall not exceed 1,000 feet.
ix.
A longer street length may be allowed through the placement of an approved traffic calming device(s) at distances described in division 5, section 22-221.D.6.b.ii. and Table V.2: Street Length and Traffic Calming.
d.
Raised platform. If traffic calming is necessary on a roadway adjacent to a school, a raised platform will be used as a crosswalk.
e.
Location from intersections. Required traffic calming devices shall be located at least 150 feet from any intersecting street, cul-de-sac, and L-shaped (elbow type) intersections (except those devices specifically designed for intersections and crosswalks).
f.
Driveway locations. The plat shall clearly identify driveway locations for lots affected by any proposed traffic calming device during the platting process to restrict driveway location to that particular location. The city may also require modification of lots fronting a proposed traffic calming device to minimize impact to these residential lots.
g.
Installation.
i.
When a series of traffic calming devices needs installation, the same type of device(s) may be used for a particular street or area. The exact placement of any required traffic calming device is subject to the city engineer's review and approval.
ii.
The city engineer reviews and approves intersection approaches that require stop sign installation.
7.
Pedestrian facilities zones.
a.
Generally. Pedestrian facilities zones are areas within a street right-of-way that restrict vehicular through-traffic and designates space for pedestrian activities like walking and cycling. Sidewalks are required on both sides of streets within the right-of-way, including culs-de-sac, in conformance with the Americans with Disabilities Act (ADA), Public Right-of-Way Accessibility Guidelines (PROWAG), and the following standards.
b.
Pedestrian facilities zone standards.
i.
Pedestrian facilities zones are required for any development.
ii.
Pedestrian facilities zones include, but are not limited to, sidewalks, street plantings, patios, bollards, lighting, street furniture, on-street parking, bicycle lanes, cycle tracks, and recreational trails.
iii.
Pedestrian facilities zones may include drought-tolerant trees planted on both sides of the street.
iv.
Pedestrian facilities zones shall be well lit by providing lighting along streets. Lighting in pedestrian facilities zones shall meet the requirements established in division 5, section 22-221.D.10.
v.
Pedestrian facilities zones may provide on-street parking, bicycle lanes, sharrows, and cycle tracks per the Engineering Design Manual.
vi.
If on-street parking is allowed, then parking must encompass at least 20 percent of the street length.
vii.
All plats and associated development plans shall show pedestrian facilities zone features.
c.
Sidewalk standards.
i.
Sidewalks are required for all development. They are required as part of the platting improvements for land subdivision in all zoning districts.
ii.
Sidewalks shall be provided along all public and private streets abutting any development or redevelopment and any addition to a nonresidential structure exceeding 1,000 square feet in gross floor area.
iii.
Sidewalks shall be constructed parallel from a curb with at least three feet of space between the sidewalk and curb, except where the continuation of any existing sidewalk on adjacent property requires alternate placement.
iv.
The planning commission may require to facilitate pedestrian access from roads to schools, parks, playgrounds, or other nearby roads, perpetual unobstructed easements at least six feet in width. These easements shall be indicated on the plat.
v.
Sidewalks shall meet the construction requirements and specifications established in the Engineering Design Manual. If those standards do not apply, a sidewalk must provide a minimum width of five feet unless specifically mentioned elsewhere in this section.
vi.
Sidewalks shall be unobstructed.
vii.
Existing sidewalks shall not be removed except for the purpose of replacement.
d.
Fee in lieu of sidewalk improvements.
i.
Where an arterial street is designated for programmed capital improvements and for which the installation of sidewalks would be impractical, the applicant may, with the approval of the city engineer, pay a fee in lieu of sidewalk construction.
(A)
The fee in lieu of sidewalk improvements shall be in an amount established in the city's schedule of fees.
(B)
Fees shall be accepted to the city.
(C)
Fees shall be utilized for the costs and expenses incurred for the construction of the sidewalks at the time the capital improvements are constructed.
(D)
As used in this subsection, the fees are deemed accepted when the city receives the required funds.
ii.
For development that is subject to the fee in lieu of sidewalks, the applicant may, with the approval of the city engineer, install the sidewalks as provided by this section; provided such development shall still be subject to the applicable fee in lieu of provisions.
e.

Purpose. Storage of stormwater runoff within a stormwater management system is a common method of providing extended detention of stormwater flows for water quality protection and downstream streambank erosion protection, as well as for peak flow attenuation of larger flows for flood protection.
b.
Detention and retention ponds. Detention ponds are designed to drain a runoff volume over a specified period of time, typically 24 hours, and provide for streambank protection. Detention ponds are designed to completely drain after a storm has passed. Retention ponds also serve to drain runoff, but have the added feature of a permanent pool.
c.
Pond standards. When a detention or retention pond is used to accommodate drainage, the following standards shall apply unless otherwise provided by the city engineer.
i.
Drainage easements and features shall be included as a portion of buildable lot(s) and not as a lot by itself unless specifically authorized by the city engineer.
ii.
Ponds shall be built to the capacity to detain the rate of stormwater runoff leaving the development at or below the pre-development peak runoff rate (Q) for all storm events, including the 2-, 10-, 25-, 50-, and 100-year storms.
iii.
Extended detention and release rate.
(A)
Ponds shall provide for the extended detention of stormwater to be released at a peak rate that precludes adverse impact to downstream property, protects water quality, and prevents streambank erosion. Due to the unique nature of each site and design of the ponds, the release rate may vary, as determined by the city engineer.
(B)
Stormwater runoff may be released over 24 hours after a designed storm has passed.
iv.
In addition to showing ponds on the drainage plan, ponds shall be shown on and approved with construction plans.
v.
Pond designs shall include a maintenance plan and bond for the removal of sediment and continued operation of the pond in a clean and sanitary manner.
vi.
In order to accommodate subdivisions that are developed in phases, multiple ponds may be constructed and shall detain the runoff from associated phases and any upstream runoff contributing to the inflow of the pond.
vii.
Ponds shall be built in the first phase of the subdivision and maintained throughout construction of all phases of development that have the potential to contribute stormwater runoff into the pond. Increased runoff rates or the concentration/acceleration of runoff leading to the risk of erosion are prohibited at all points of the site development project.
viii.
In some circumstances, the location of a property being subdivided for development within the drainage basin may make the requirement to provide detention/retention unnecessary. The city engineer has the right to review the engineering basis for such a determination presented by the property owner's engineer and waive the detention/retention requirement if deemed appropriate.
d.
Pond design requirements. All ponds shall meet the design requirements established in the city's Engineering Design Manual.
e.
Method for determining peak flows. The determination of peak flows shall use one of the methods identified in the Engineering Design Manual, or another commonly accepted method as approved by the city engineer.

(Ord. No. 2806NS, § 1(Exh. A), 8-19-2024)
A.
Purpose. Performance guarantee and security requirements are established to address those circumstances under which an applicant wishes to receive final plat approval and record the approved final plat before installing required infrastructure and public improvements. The provisions help ensure that funding is in place to cover the cost of installing any required improvements that are not installed by the applicant within a reasonable period of time after receiving final plat approval.
B.
Term of agreement. The term of a performance guarantee shall not exceed two years. If the applicant has not completed the required infrastructure and public improvements within the two-year period, the director is authorized to approve one extension of up to six months in duration. Any additional extensions or extensions of a longer duration require approval of the planning commission. Approval authorities/decision-making bodies are authorized to require updated improvement cost estimates and additional security as a condition of any extension granted.
C.
Form and amount of security.
1.
Security must be in the form of an irrevocable letter of credit, cash, or another instrument readily convertible to cash, as approved by the city attorney or district attorney. The performance guarantee and security must be conditioned upon the performance of all work necessary to complete the required infrastructure and improvements.
2.
The estimated total cost of any required infrastructure and improvements that have not been installed by the applicant prior to recording of the approved final plat must be itemized by improvement type and certified by the applicant's registered engineer. Cost estimates must be based on industry norms within Shawnee.
3.
The amount of the performance guarantee must equal at least 110 percent of the estimated total cost of all required infrastructure and improvements that have not been installed by the applicant prior to recording of the approved final plat.
D.
Default and use of security. If the applicant fails to properly install required infrastructure and improvements within the term of the guarantee and any approved extension, the guarantee will be deemed in default. In the case of default, the city is authorized to draw or foreclose upon the security funds to fund completion of the required infrastructure and improvements or to contract for installation of the required infrastructure and improvements. If the cost of completing the required infrastructure and improvements exceeds the security amount, the applicant is liable for all excess costs. Any security funds to be drawn upon or foreclosed will be subject to an administrative fee that reflects the city's actual costs associated with preparing bid documents and preparing and administering a contract for the work to be completed.
E.
Release of security. The security must be released once all the following occur:
1.
The conditions of the performance guarantee have been completed to the satisfaction of all agencies with jurisdiction over the improvements;
2.
Any required maintenance guarantee has been provided per applicable city or county regulations;
3.
A final inspection has been conducted by the city engineer or other qualified professional selected by the city engineer and retained by the applicant;
4.
Written evidence has been submitted that all owners of the infrastructure and improvements have accepted ownership of the improvements;
5.
The applicant has provided as-built or record plans showing monuments, streets, curbs, sidewalks, and all other infrastructure and public improvements as they were installed; and
6.
All required certifications of completion have been provided.
F.
Plat vacation. Vacation of the plat as provided by state statute removes the obligation to construct improvements and constitutes grounds for release of any remaining financial guarantee.
G.
Maintenance guarantees and security.
1.
Maintenance guarantees and financial security must be provided in accordance with applicable city regulations.
2.
Maintenance bonds shall be filed in the following amounts:
a.
Paving, grading, and drainage:
i.
One hundred percent for one year;
ii.
Ten percent for four years.
b.
Water and wastewater/sewer: Ten percent for two years.
H.
Perpetual maintenance of common areas and improvements.
1.
Maintenance obligation for common areas and improvements.
a.
The obligation for perpetual maintenance of any common areas and public or private improvements within a development must be established by the developer and approved by the planning commission. This obligation must be provided for in the plat, or for developments not required to be platted, by a deed restriction or other appropriate document recorded with the county clerk.
b.
If multiple property owners will be responsible for perpetual maintenance and control of common areas and public or private improvements, a property owners association must be established. Each property owner, by acceptance of a deed to a property within the development, will be deemed to have agreed to be a member of the property owner's association and be subject to assessment for maintenance of the common areas and public or private improvements.
c.
If the entire development is to remain under single ownership, the common areas and public or private improvements must be maintained by the owner of the property.
2.
Declarations and covenants.
a.
Declarations and covenants guaranteeing ongoing maintenance of common areas and public or private improvements must be established within a deed of dedication accompanying a plat or, for developments subject to these regulations but not required to be platted, by a deed restriction or other appropriate document recorded with the county clerk.
b.
The declarations and covenants must expressly authorize the city to correct maintenance deficiencies in areas containing public improvements that the property owner or property owners association is required to maintain, and to recover actual costs and any legal fees from the subject property owner or property owners association if maintenance duties are not carried out, and to establish and enforce a lien against the property in the development for recovery of the costs and fees.
