1 Volume II Design Criteria 2014 Edition

2 DIVISION 2200 STREETS SECTION 2205 STREET DESIGN 1.01 GENERAL The purpose of these criteria is to provide uniform procedures for designing and checking the design of both public and private streets within the City. A. Design Criteria to be Used: All street improvements shall be designed in accordance with their classification and alignment as shown on the Circulation Plan most recently adopted by the Governing Body in the document entitled Comprehensive Plan for the City of Shawnee. B. Modification of Design Criteria: These specific design criteria have been established and are applicable to the types of conditions ordinarily encountered in typical street design. Other special situations may be encountered that require added criteria or more complex design than included herein. However, the Engineer must obtain the authorization of the City Engineer prior to using such additional criteria or more complex design. C. Additional Design Criteria and Specifications: In addition to these criteria, street improvements shall be designed and constructed to conform to all applicable codes, regulations, and ordinances as established by the City. When additional criteria or specifications are required, the design shall be in accordance with the latest edition of the following documents and the current interim supplements thereto: 1. Standard Specifications and Design Criteria. Kansas City Metropolitan Chapter of the American Public Works Association (APWA). 2. Standard Specifications for State Road and Bridge Construction. Kansas Department of Transportation (KDOT). 3. A Policy on Geometric Designs of Highways and Streets. American Association of State Highway and Transportation Officials (AASHTO). 4. Roadside Design Guide. American Association of State Highway and Transportation Officials. 5. Manual on Uniform Traffic Control Devices for Streets and Highways. Federal Highway Administration. 6. Design of Pavement Structures. American Association of State Highway and Transportation Officials. D. KDOT Rights-of-Way: All construction within rights-of-way under the control or jurisdiction of the State of Kansas shall be reviewed and approved by the Kansas Department of Transportation. Plans submitted to the City of Shawnee shall reflect all changes or corrections as required by the Kansas Department of Transportation. Additionally, the Engineer shall provide a copy of the required state permit prior to the issuance of any public improvement permit CLASSIFICATION OF STREETS The section presents the classification system developed to define the characteristics and guide the design of the various streets within the City. Streets are classified based on their ultimate Division 2200 Streets Section 2205 Street Design Revised 2014

3 function at build-out of the City. Therefore, an unimproved or proposed street may not initially be built for its ultimate roadway design although developing areas should be planned so that no need will arise in the future to widen a minor collector or a local street. The classification of streets is generally defined as follows: A. Major Arterials: These roadways fall into the following functional classification subcategories: Interstates and Other Freeways, Expressways, and Other Principal Arterials, such as State highways. As such, major arterials are limited to roadways on the State highway system and accordingly are designed to State criteria, which are not included in this Manual. These roadways primarily provide for through traffic movement connecting the City with other cities and serving the major centers of activity in the metropolitan area as well as statewide and interstate travel. The roadways are typically divided and are intended to provide a minimum of four (4) freely moving traffic lanes with a landscaped median. Intersections at grade are either prohibited or highly restricted. Access to adjacent properties is usually prohibited from freeways and expressways although highlycontrolled access may be allowed from a principal arterial. Major arterials have high speeds and high traffic volumes. Speeds are typically fifty-five (55) miles per hour (mph) or above. The average daily traffic (ADT) is typically above twenty thousand (20,000) vehicles per day (vpd). Trip lengths on these roadways will typically be several miles long. Spacing of major arterials is generally greater than two (2) miles. B. Minor Arterials: These roadways are the primary thoroughfares within the City providing traffic movement between major activity centers, such as shopping centers, business and office centers and industrial parks, secondary schools and colleges, hospitals, large churches and major recreational areas. Geometric design and traffic control measures are used to expedite the safe movement of through traffic with intersections at grade and limited access to adjacent properties. Direct access to residential properties should not be permitted. The minimum roadway width of a minor arterial is intended to provide a minimum of two freely moving traffic lanes up to four (4) or more lanes with a divided median. Moderate to high speeds (35 to 45 mph) are typical for undivided roadways, while higher speeds (45 to 55 mph) may be established for divided roadways with landscaped medians. Moderate to high traffic volumes (desirable minimum ADT of 3,000 vpd, typical ADT of 10,000 to 30,000 vpd) are typical characteristics of minor arterials. Typical trip lengths on minor arterials will be one (1) to two (2) miles long. Spacing of minor arterials is typically one (1) mile. C. Major Collectors: These roadways are the secondary thoroughfares within the City providing traffic movement between less intense developments, such as low intensity commercial developments, apartment complexes, residential subdivisions, schools, churches, and parks. Although the primary function of these roadways is to move traffic, access to adjacent properties is a slightly more important function. Access to nonresidential properties occasionally occurs, but direct access to single-family and two-family residential properties should not be permitted. The minimum roadway width of a major collector is intended to provide two freely moving traffic lanes with a continuous center, two-way, left-turn lane. Moderate speeds (35 mph) and low to moderate traffic volumes (ADT generally less than 10,000 vpd) are typical of characteristics of major collectors. Typical trip lengths on major collectors will be about one (1) mile or less. Spacing of major collectors is typically one (1) mile. D. Minor Service Collectors: These roadways provide a nearly equal balance to both through traffic movement and access to adjacent properties. Minor service collectors provide a connection between local service streets and the major collector and the arterial street systems. The roadway width of a minor service collector is intended to provide two freely moving traffic lanes while accommodating emergency on-street truck parking. Low Division 2200 Streets Section 2205 Street Design Revised 2014

4 to moderate speeds (30 to 35 mph) and low to moderate traffic volumes (ADT generally about 2,500 to 5,000 vpd) are typical of minor service collectors. Typical trip lengths on these roadways will be about a half (1/2) mile or less. Spacing of minor service collectors is typically a quarter to a half (1/2) mile. E. Minor Residential Collectors: These roadways, like minor service collectors, provide a nearly equal balance to both through traffic movement and access to adjacent properties. Minor residential collectors provide a connection between local residential streets and the major collector and the arterial street systems. The roadway width of a minor residential collector is intended to provide two freely moving traffic lanes while accommodating emergency on-street car parking. Direct access to non-residential properties occasionally occurs, but direct access to single-family and two-family residential properties should be avoided whenever possible. Low speeds (25 to 30 mph) and low traffic volumes (desirable maximum ADT of 3,000 vpd) are typical of minor residential collectors. Typical trip lengths on these roadways will be about a half (1/2) mile or less. Spacing of minor residential collectors is typically a quarter to a half (1/2) mile. F. Local Service Streets: These roadways provide direct access to adjacent properties with local traffic movement limited to the immediate multi-family residential, commercial, or industrial development. The roadway width of a local service street is intended to provide two traffic lanes while accommodating occasional on-street truck parking. Low speeds (25 to 30 mph) and low traffic volumes (desirable maximum ADT of 2,500 vpd) are typical of local service streets. Trip lengths on these roadways are intended to be quite short, typically a quarter mile or less. Spacing of local service streets is based on the layout of the immediate development, but is typically less than six hundred sixty (660) feet. Local service streets usually carry no through traffic and should be designed as only loop streets and cul-de-sacs. G. Local Residential Streets: These roadways provide direct access to abutting singlefamily and two-family residential properties with very limited traffic service within the immediate neighborhood. On-street parking is to be expected on a local residential street, which typically limits traffic movement to a single lane. Local residential streets have the lowest speeds (25 mph) and lowest traffic volumes. Typically the ADT is between seventy-five (75) and three hundred fifty (350) vpd with the desirable maximum ADT generally less than one thousand (1,000) vpd (desirable maximum ADT of 200 vpd for culde-sacs and 400 vpd for loop streets). Trip lengths on these roadways are intended to be quite short, typically a quarter mile or less. Spacing of local residential streets is based on the layout of the immediate neighborhood, but is typically less than four hundred forty (440) feet. Local residential streets should be designed to discourage through trips STREET DESIGN CRITERIA This section presents specific criteria to be used when designing streets: A. Specific Design Criteria: Refer to Table and the Standard Details for specific design criteria based on street classification. All street design is subject to approval by the City Engineer. B. General Design Criteria: 1. Consideration shall be given to the horizontal and vertical alignment of roadways where they connect to existing streets or where roadways may be extended in the future. Division 2200 Streets Section 2205 Street Design Revised 2014

5 2. Local residential streets shall be curved wherever possible to avoid conformity of lot appearance. Street grades shall conform as closely as possible to the original topography. A combination of steep grades and curves shall be avoided. 3. The rigid rectangular gridiron street pattern in new developments should be discouraged and the use of curvilinear and loop streets shall be encouraged where such use will result in a more desirable layout. 4. Streets shall be extended to the boundary of the new development, unless prevented by topography, or unless the City Engineer determines such extension is not necessary. At any location where a neighboring property is undeveloped and the street must temporarily end at the boundary of the development, a sign shall be posted stating the City s intent to extend the street onto adjacent property at a future date. 5. Whenever a proposed development abuts unplatted land or a future development phase of the same development, street stubs shall be provided as deemed necessary by the City Engineer. All street stubs shall be provided with a temporary turnaround. C. Sidewalks: Refer to the Standard Details for location, dimension, and material requirements. The following additional requirements also apply: 1. Sidewalks adjoining the roadway curb shall have a minimum width of six (6) feet. A sidewalk serving as a two-way, multipurpose facility for both pedestrians and bicycles shall have a width of ten (10) feet. 2. Sidewalks shall typically be placed one (1) foot from the outside edge of the right-ofway. Where a sidewalk must be placed two (2) feet or less from the back of curb, the width of the sidewalk shall extend to the back-of-curb. 3. Sidewalk ramps shall be required at all planned sidewalk-curb intersection, including at the top of a T-intersection of two streets. 4. For sidewalks less than five (5) feet, wheel chair passing zones are required at intervals of two hundred (200) feet. The passing zones shall be constructed to ADA requirements. Driveway approaches are acceptable alternatives to dedicated passing zones if they meet ADA requirements for slope and size. D. Connection to Existing Pavement: Where a new street is to connect to an existing street, all deteriorated or cracked asphalt and curb within five (5) feet of the connection point shall be removed to a point where sound material is found. Existing pavement is to be saw cut full depth for the entire width of the street. This subgrade shall be prepared to the standards of the new improvement and repaved with the new construction. E. Access to Major Streets: When a development is proposed that would abut a major street, it shall be designed to provide access to those lots abutting the major street from a frontage street or interior local street. Access to a reverse frontage lot or corner lot shall be restricted to the street with the lower street classification. Access rights for these lots to the major street shall be dedicated to the City and recorded on the final plat for the development. F. Right-of-Way Grades: The finished cross slopes within the limits of the right-of-way shall be between on quarter (1/4) inch vertical to one (1) foot horizontal, minimum, to one-half (1/2) inch vertical to one (1) foot horizontal, maximum, except for sidewalks which shall meet American Disabilities Act (ADA) requirements. Back slopes beyond the right-of-way line shall be no steeper than four units horizontal to one unit vertical (4:1) although flatter is desired. Division 2200 Streets Section 2205 Street Design Revised 2014

6 G. Intersection Angle: It is desirable for all roadways to intersect at right angles; however, no intersection shall have an angle of less than eighty (80) degrees or more than one hundred (100) degrees. H. Sight Distance at Intersections: Sight distance triangles at intersections shall be in accordance with the current edition of A Policy on Geometric Design of Highways and Streets. Every effort shall be made to select intersection locations so that the maximum sight distance is possible. As part of the plan review the Engineer shall submit calculations for intersection sight distances at each stop, yield, or controlled intersection approach. I. Traffic Control: All traffic control devices shall comply with the standards and specifications of the current edition of the Manual on Uniform Traffic Control (MUTCD). J. Curb Radii: When two streets of different classifications intersect, the higher classification street shall govern the curb radii dimension. Equivalent three-center compound curves may be used in lieu of single radius curve if the design vehicle can be accommodated. Curb ends facing the flow of traffic shall have a five (5) foot taper from full height to matching existing condition. The curb radii shall be adequately designed to prevent turning vehicles form encroaching into the posing traffic lane. K. Drainage at Intersections: Street grades at intersections shall have a minimum slope of one-half percent (0.5%). Grades of at least one percent (1%) are preferred to prevent ponding and accumulation of silt. L. Intersecting Major Streets: Where major streets intersect each other, the crowns of both streets shall be uniformly transitioned into a plane at the intersection. Changes from one cross slope to another should be gradual. M. Compound Curves: When a compound horizontal curve is used, the radius of the flatter curve shall not exceed one one-half (1.5) times the radius of the sharper curve. N. Off-Center Street Intersections: Off-center street intersections shall be separated by a minimum centerline to centerline dimension of at least one hundred fifty (150) feet. O. Pavement Transitions: Reduction in pavement width in the direction of traffic flow shall be accomplished by a taper. The minimum desirable length for a merging taper shall be determined by the following formulas: 60 where the posted speed limit is 45 mph or less (where the posted speed limit is greater than 45 mph) where: L = length of taper, feet W = width of the closed lane, feet S = design speed, miles per hour (mph) P. Cul-de-sacs: At locations where streets are to be terminated and vehicular connection between adjacent streets is not required, the termination shall be a cul-de-sac. On a street longer than one hundred fifty (150) feet, such cul-de-sacs shall be constructed with a minimum radius of forty-eight one-half (48.5) feet to the back of curb provided there is no island located in the cul-de-sac. On a street shorter than one hundred fifty (150) feet, such cul-de-sacs may be constructed with a minimum radius of thirty-eight one-half (38.5) feet to the back of curb provided there is no island located in the cul-de-sac. However, a residential U-drive with an island is preferred for a short street. Division 2200 Streets Section 2205 Street Design Revised 2014

7 Loop streets and curvilinear streets that connect with other streets are preferable for circulation patterns, maintenance, snow removal, and police and fire protection. Cul-desac streets are permitted where a vehicular connection is not required by the Planning Commission between adjacent streets or adjoining properties. A cul-de-sac street shall terminate at a permanent turnaround. The length of a cul-de-sac street is measured from the back-of-curb of the intersecting street along the centerline to the back-of-curb at the top of the turnaround. These requirements shall apply equally to a grouping of cul-de-sac streets having a single common entrance. When an island is constructed in the center of the circular turnaround for a local residential cul-de-sac street, the width of the roadway around the island shall be twenty-seven (27) feet measured from back-of-curb to back-of-curb. Islands are not permitted in the center of a circular turnaround on any other street classifications. When an island is constructed in the turnaround as part of a privately financed project, the responsible party shall execute a maintenance agreement for the island. Cul-de-sacs should not be placed closer than fifty (50) feet to the right-of-way of an adjacent street or the boundary of the development. The Planning Commission may require the dedication of any appropriate easement for utilities, drainage, or pedestrian traffic to adjacent streets, open spaces or properties. Q. Temporary Turnarounds: At locations where streets will be temporarily terminated and which will be extended at a later date, and said street extends beyond the intersection of an adjacent street more than one hundred fifty (150) feet, measured from the back-of-curb of the intersecting street along the centerline to the back-of-curb at the top of the turnaround. A temporary cul-de-sac shall be constructed with a minimum radius of thirtyeight (38) feet. The length street is. The temporary cul-de-sac shall be constructed using a minimum thickness of eight (8) inches of asphaltic concrete and comply the requirements of the Standard Details. The temporary turnaround shall be constructed within the limits of a temporary easement. Temporary turnarounds shall be located so that they do not interfere with permanent development. They should normally be located on property adjacent to the property to be served. For new subdivision plats, they should be located on property beyond the limits of the plat. Where a temporary turnaround is required at the boundary of a development, a halfcircle turnaround, with a ribbon curb, shall be constructed on the side of the street opposite the sidewalk. The turnaround shall be constructed within the limits of a temporary easement dedicated on the final plat with a notation that the portion of the easement shall revert to the abutting property owner without release after the street is extended and the turnaround is removed. This requirement does not preclude a developer from acquiring a temporary easement from an adjacent property owner to permit the construction of a full-circle turnaround. Permanent dead-end streets are prohibited. R. Obstructions: Rigid structures, such as poles and hydrants, shall be placed a minimum horizontal distance of two (2) feet from the face-of-curb to the edge of obstruction. When required, guardrails and barricades shall be installed in accordance with the current edition of Roadside Design Guide (AASHTO). Vertical clearance of a minimum fourteen one-half (14.5) feet shall be provided. Along sidewalks, a minimum vertical clearance of seven (7) feet shall be provided. Division 2200 Streets Section 2205 Street Design Revised 2014

8 S. Roundabouts: Roundabouts shall be designed in accordance with AASHTO, FHWA Roundabout Design Guide, and MUTCD. T. Underdrains: In areas that have known subsurface moisture problems, underdrains or drainage blankets shall be designed to protect the street improvements. Refer to Standard Details for installation requirements. U. Access for the Disabled: Ramps shall be required at all planned sidewalk-curb intersections in accordance with the American Disabilities Act (ADA). V. Survey Monument Boxes: Monument boxes shall conform to the Standard Details and shall be installed at all quarter section corners involved in the street construction. The monument boxes shall be set by a Kansas licensed Land Surveyor. W. Pavement Markings: Pavement markings are required at the discretion of the City Engineer; however, they are not typically required on local residential or local service street DRIVEWAY DESIGN CRITERIA This section presents the criteria to be used when designing residential driveways and service driveways providing access to multi-family, commercial, and industrial developments. A. General Standards: The City Engineer shall approve the location, dimension, design, construction requirements, and materials of all driveway approaches prior to lot construction. All such approaches shall adhere to the following general standards: 1. Construction of driveways within the functional area of a roundabout or an intersection, including left-turn lanes, right-turn only lanes, and deceleration lanes and tapers is prohibited due to the potential for vehicular weaving conflicts, unless the City Engineer determines that no other access point to the property is available. 2. Driveways must be designed and located to provide a vehicle entering onto a roadway with an unobstructed view, which provides ASSHTO compliant sight distance. 3. Driveways should intersect the street at right angles; however, driveways shall intersect at an angle no less than eighty (80) degrees nor more than one hundred (100) degrees. 4. No portion of the driveway shall extend across the property line (including the prolongation of the property line through the right-of-way), including the curb return or flare. 5. Driveways across from median openings shall be consolidated whenever feasible to coordinate access at the median opening. The City Engineer will make the final determination on all driveway locations. B. Driveway Grades: Driveway grades shall conform to the typical section of the street within the right-of-way. Any deviation shall attain a minimum elevation of six (6) inches above the gutter elevation within the right-of-way with a maximum grade of eight percent (8%). The algebraic difference in grades at the right-of-way on crest drives shall be eight percent (8%) maximum and on sag drives shall be twelve percent (12%) maximum. The maximum driveway grade outside the right-of-way shall be fifteen percent (15%) and the minimum shall be one percent (1%). Driveways that are to be utilized as part of the City s sidewalk system shall comply with ADA requirements, for the equivalent width of the abutting sidewalk. Division 2200 Streets Section 2205 Street Design Revised 2014

9 C. Auxiliary Lanes: The City Engineer may require auxiliary lanes when deemed necessary due to traffic volumes or where a safety or operational problem exists. Left-turn and rightturn lanes shall be designed in accordance with the current edition of A Policy on Geometric Design of Highways and Streets. D. Drainage Facilities: All driveways and the parking areas they serve shall be provided with adequate drainage facilities. Stormwater runoff is prohibited from draining directly from the property by way of a driveway, or curb cuts or flumes from the parking area, onto adjoining streets or property. Drainage facilities shall be in accordance with the provisions of Division 2600 Storm Drainage. In the event storm sewer facilities do not exist within five hundred (500) feet of the property, the City Engineer may waive this requirement when the runoff does not exceed the rate permitted as overland flow and the cost of the stormwater drainage extension represents a substantial portion of the total cost of the development. E. Throat Widths for Residential Driveways: The throat width, excluding the required triangular flares, of a residential driveway shall not exceed the following: Type of Residence Maximum Throat Width (1) Edge-to-Edge (feet) Single-Family (1- to 3-car garage) 24 Two-Family (separated garages) 24 Two-Family (side-by-side garages) (2) 32 (1) No residential driveway shall have a throat width of less than twelve (12) feet, measured from pavement-edge to pavement-edge. (2) Combined driveways serving two side-by-side garages are discouraged because of their impact on the on-street parking. Such driveways shall only be allowed for those lots shown on a driveway location plan for a development submitted to and approved by the Planning Commission upon the recommendation of the City Engineer. F. Throat Width for Non-Residential Driveways: The throat width, excluding the required triangular flares or curb returns, shall be designed to accommodate the projected traffic volume and type of vehicles anticipated at the individual driveway based on the general land use intensity of the development. 1. One-way Driveways: Single-lane driveways for entering or exiting a property are sometimes appropriate for access management purposes, but they can pose a safety hazard if the parking areas they serve are not properly designed. The Engineer must ensure that the circulation pattern designed for the parking area restricts and discourages the movement of vehicles through the driveway in the wrong direction. The throat width for a one-way non-residential driveway shall be a maximum of twenty-one (21) feet, measured from back-of-curb to back-of-curb. 2. Two-Driveways: Standards for non-residential two-way driveways are as follows: Number of Lanes Lane Width (1) (feet) Entry Exit Entry Exit Throat Width (3) Medians (2) Back-to-Back (feet) Not Applicable (3) Not Applicable (4) Not Landscaped (5) 40 Division 2200 Streets Section 2205 Street Design Revised 2014

10 Number of Lanes Lane Width (1) (feet) Entry Exit Entry Exit Throat Width (3) Medians (2) Back-to-Back (feet) Landscaped (6) Not Applicable (7) Not Landscaped (5) Landscaped (6) Not Landscaped (5) Landscaped (6) 64 (1) Lane widths are measured from pavement edge (face of curb) to center of the pavement marking. (2) The entry and exit lanes of a driveway serving higher traffic volumes shall incorporate a raised median as a channelization feature to separate the entry and exit sides of the driveway. The length of the median shall be equal to the throat length of the driveway. The median shall be outlined with a solid yellow line four (4) inches wide. Multiple entry and exit lanes shall be separated by a solid white line four (4) inches wide. The City Engineer may allow the use of a painted median instead of a raised median where truck off-tracking is a problem. The painted median shall be outlined with double solid yellow lines each four (4) inches wide and diagonal solid yellow lines six (6) inches wide spaced forty-eight (48) inches apart along the length of the median. (3) The City Engineer may allow or require wider throats where deemed necessary to accommodate trucks with longer wheelbases. (4) Entry and exit lanes are not normally defined, but may be separated by a solid yellow line four (4) inches wide. (5) A driveway median that is not landscaped shall be four (4) feet wide, measured from back-of-curb to back-ofcurb, and have a surface color that contrasts with the driveway pavement surface. (6) A landscaped driveway median shall be eight (8) feet wide, measured from back-of-curb to back-of-curb. (7) When an undivided driveway is permitted with multiple exit lanes, the entry and exit sides of the driveway shall be separated by double solid yellow lines each four (4) inches wide. The exit lanes shall be separated by a solid white line four (4) inches wide. Paint lines shall extend the full length of the driveway throat. G. Throat Length for Residential Driveways: Residential driveways shall be a minimum of twenty (20) feet in length measured from the right-of-way to the garage. H. Throat Length for Non-Residential Driveways: The length of a non-residential driveway shall be designed to accommodate the projected traffic volume anticipated at the individual driveway based on the general land use intensity of the development. Throat length shall be as follows: Roadway Classification Minimum Throat Length (1) (feet) Minor Arterial 40 Major Collector 40 Minor Service Collector 20 Minor Residential Collector 20 Local Service Street 20 Local Residential Street 20 (1) Community shopping centers (supermarkets, drug stores, etc.) and office centers having a gross leased area of more than 100,000 square feet shall have a minimum throat length of sixty (60) feet. The minimum throat length for a signalized driveway shall be eighty (80) feet. Division 2200 Streets Section 2205 Street Design Revised 2014

11 I. Driveway Curb Returns and Triangular Flares: All residential and non-residential driveways are required to include either curb returns or triangular flares at the intersection of the driveway with the roadway. The radii of curb returns and the width of triangular flares shall be adequate to serve the volume of traffic and provide for efficient movement of vehicles onto and off of the public street, but shall not be so excessive as to pose safety hazards for pedestrians, bicycles, or other vehicles. The City Engineer may allow or require longer curb return radii where deemed necessary to accommodate trucks with longer wheelbases. Roadway Classification Triangular Flare Width (feet) Curb Return Radius (feet) Minor Arterial 5 30 Major Collector 5 25 Minor Service Collector 5 25 Minor Residential Collector 3 20 Local Service Street 5 25 Local Residential Street PLAN REQUIREMENTS This section governs the preparation of improvement plans for street projects.
