adverse ecological impacts. Therefore, controls shall be implemented for the 10%

and 50% storms in every instance.

General location and width of stream setback are shown on the City web site at

www.ci.lenexa.ks.us under the departments, public works, watershed section of the web site(Or at www.raintorecreation.org > ordinance/codes > Stream Setback). Actual stream setbacks

must be based on surveyed locations. Where one acre or more will be disturbed by the

construction, a National Pollutant Discharge Elimination System (NPDES) permit will be

obtained from the state.

In addition to the Section 5600 requirements, as adopted by Lenexa, All Engineered

Channels shall have a minimum slope of 3%. Vegetated Swales, when used as a BMP, may

have a slope lower than 3%. Open Channels, as defined by Section 5600, may also have

slopes below 3%, when allowed by Section 5600. Engineered Channels and Open Channels

shall be as defined by Section 5600. Vegetated Swales shall be defined per the MARC

manual on BMPs, as adopted by Lenexa.

In addition to the above criteria, underdrain shall be placed around the perimeter of any cul-

de-sac or subdivision entry island. This is not a design criteria, but rather a construction

requirement, as stated below in the plan requirements.

The City of Lenexa General Conditions, Technical Specifications, and Standard Drawings

shall control the construction, equipment, and materials of all public improvements.

Prior to beginning any construction, submittals are required for materials as listed in the

Technical Specifications.

STREET LIGHTS

The street lighting system shall consist of one or more control centers, the distributionsystem, street light poles, luminaires and any other appurtenances required to provide a

complete, operable street lighting system. Components of the system shall conform to the

City of Lenexas Technical Specifications.

The street lighting design and layout shall be based on the ILLUMINANCE criteria for

continuous lighting in the latest edition of the American National Standard Practice for

Roadway Lighting, Illuminating Engineering Society (IES). The standard spacings in the

table below have been determined based on street classification.

(1) LLF = 0.69

(2) as determined by a photometric analysis

Note: At locations where additional lighting may be beneficial such as around curves or at

intersections, the pole spacings should be reduced to improve the lighting levels.

Street lighting in residential areas shall consist of shoe box-style luminaires mounted to 20-

foot (6 m) round, tapered poles. The luminaires and the poles shall have an anodized dark

bronze finish, as specified in the Technical Specifications. The use of post-top luminaires

mounted to 14-foot (4.27 m) poles requires special approval by the City. Street lighting in

non-residential areas shall consist of street light poles with 30-foot (9 m) or 40-foot (12 m)

mounting heights. The use of single member luminaire arms (Type A) is preferred and

should be used whenever possible in lieu of the truss-style luminaire arms (Type B).

All street light poles shall have a minimum setback of 3 feet (0.9 m) from the back of curb to

the center of the pole. In addition, street light poles in residential areas shall be installed on

the property lines or as close to the property line as possible to avoid conflicts with

driveways and to minimize the amount of ambient street light shining into adjacent houses.

The lamps shall be High Pressure Sodium (HPS) and shall be one of the following:

a. 400-watt lamps shall be rated at 50,000 lumens with a 40,000-hour rated life,b. 250-watt lamps shall be rated at 30,000 lumens with a 40,000-hour rated life,


15/39

CITY OF LENEXA




8/16/2005

15

c. 150-watt lamps shall be rated at 16,000 lumens with a 40,000-hour rated life.Street lights in residential areas shall be 150-watt HPS lamps while non-residential areas

shall contain 250-watt or 400-watt HPS lamps.

The distribution system shall be underground. Conduit is required in every location where

cable passes under any type of paved surface or behind storm sewer inlets. In residential

areas where future driveways and utility connections are likely to occur, conduit is required

along the entire length of the run between street light poles. Conduit is also required along

the entire run between poles in areas where rocky terrain exists. Except where it crosses the

street, distribution cable shall be behind the back of curb or outside the edge of pavement.

The distribution cable shall be sized so that the voltage drop does not exceed five percent

(5%) at any point in the system. The Engineer MUST submit voltage drop calculations to

support this requirement.

Conductors for the distribution system shall typically be No. 4 AWG but in no case largerthan No. 2 AWG. Pole and bracket cable shall be No. 12 AWG, 2-conductor stranded copper

conforming to IMSA Specification 19-1.

All street lighting circuits shall be 240 volts and shall be laid out in a way that maximizes the

use of each control center. Each lighting circuit shall be contained in a separate conduit,

except for the conduit run between the control center and the adjacent junction box. In that

case, one 3-inch (75 mm) conduit shall be installed from the control center to a Type II

junction box that is installed adjacent to the cabinet. Distribution cable for each of the

lighting circuits shall be routed through this conduit to the junction box.

Junction boxes shall be installed on each end of a pavement crossing where direct buried

cable begins and ends. Junction boxes shall also be used where splices in the distribution

cable are required or where sharp 90-degree bends in conduit are required. The installation

of junction boxes in sidewalks should be avoided while the installation of boxes in streets

and driveways is unacceptable. Type II junction boxes shall be used where more than two

conduits enter/exit the box. Type I junction boxes shall be used where one or two conduits

enter/exit the box. Junction boxes shall be installed at least 2 feet (0.6 m) from the back of

curb to the center of the box and no closer than 2 feet (0.6 m) to any street light pole.

The electrical system shall conform to the requirements of the National Electrical Code, the

National Electrical Safety Code and service standards issued by the utility which will be

supplying power to the street lighting system. The Engineer shall coordinate and verify the

location of proposed feed points with the utility company to ensure availability of service.

Control centers should be located adjacent to the sidewalk or at least 5 feet (1.5 m) from the

back of curb to the center of the control center where no sidewalk exists. When the location

of the control center has been finalized and power has been verified with the utility company,

the City will provide the Engineer with an address and an identification number for each


16/39

CITY OF LENEXA




8/16/2005

16

proposed control center. The address and identification number shall be placed in the lower

right corner of the street lighting plan sheet above the titleblock. In addition, luminaires shall

be numbered using the identification number. For example, street lights on Circuit 1 on

Controller AB should be labeled as AB 1-1, AB 1-2, AB 1-3, etc. If twin luminaires are

mounted to the street light pole, the luminaires should be labeled as AB 1-1 and 1-2, AB 1-3and 1-4, AB 1-5 and 1-6, etc.

TRAFFIC SIGNALS

The traffic signal system shall consist of the signal controller, signal poles, signal heads,

cable, conduit, vehicle detectors and any other appurtenances required to provide a complete,

operable traffic signal system. Components of the system shall conform to the City of

Lenexas Technical Specifications.

Signal poles shall typically be located a minimum of 6 feet (1.8 m) from the back of curb to

the center of the pole. When pedestrian signal heads are used, signal poles with push buttonsshould be placed at locations that are convenient to the pedestrian. However, the City does

not require that poles be aligned with the crosswalk locations.

When designing a traffic signal whether its an existing signal or a new signal, the signal

phasing shall be discussed with the City in order to determine the number and sequence of

the phases. The City uses a standard phasing sequence which is shown below:

Phase 1 southbound left

Phase 2 northbound through

Phase 3 westbound left

Phase 4 eastbound through

Phase 5 northbound left

Phase 6 southbound through

Phase 7 eastbound left

Phase 8 westbound through

Traffic signal heads shall be placed in accordance with theManual on Uniform Traffic

Control Devices (MUTCD). In addition, the City has developed some guidelines in an effort

to standardize the placement of signal heads:

Typically, a standard three-section head (Signal Head A) should be centered overeach EXITING lane for all through lanes of traffic.

When a left-turn lane is provided without left-turn phasing, no separate signal headshould be provided for the left-turn movement.

When protected left-turn phasing is specified, the three-section head (Signal Head B)should typically be centered over the left-turn lane. Likewise, when dual left-turn

movements are specified, a separate Signal Head B indication should be centered over


17/39

CITY OF LENEXA




8/16/2005

17

each left-turn lane. In addition, a separate LEFT TURN SIGNAL sign (R10-10) shall

accompany each Signal Head B indication.

When protected/permissive left-turn phasing is specified, a four-section head (SignalHead Dd) should be placed over the extension of the channelization line between the

left-turn lane and the adjacent through lane. Signal Head Dd shall be accompanied bya LEFT TURN YIELD ON symbolic green ball sign (R10-12).

All traffic signal and pedestrian indications shall be LED displays. In addition, backplates

shall be provided for all traffic signal heads that are mounted to the mast arm. Signal heads

that are mounted to the signal pole should not be equipped with backplates.

Opticom emergency preemption equipment shall be shown on the signal plan and shall be

designed for ALL directions of traffic at an intersection.

When vehicle detector loops are used, advance detector loops shall be placed at standard

distances. The figure below illustrates these various distances and are based on the posted

speed limit. Please note, the distances are measured from the BACK of the stop bar to the

BACK of the loop.

Standard loop dimensions for stop bar detection include 6 ft. x 50 ft. (1.8 m x 15 m) and 6 ft.

x 6 ft. (1.8 m x 1.8 m) detector loops. When a main road is programmed to be on recall, the 6

ft. x 6 ft. (1.8 m x 1.8 m) detector loop should be used on the main road approaches for stop

bar detection. The 6 ft. x 50 ft. (1.8 m x 15 m) loops should be used in all other cases and for

all left-turn lane loops. All advance detector loops shall be 6 ft. x 6 ft. (1.8 m x 1.8 m)

detector loops. In order to determine where to place a 6 ft. x 50 ft. (1.8 m x 15 m) stop bar

detector loop, the City typically places the FRONT of the loop 15 to 20 feet (4.5 to 6.0 m)

from the nearest edge of the through lane of the intersecting road extended. For 6 ft. x 6 ft.(1.8 m x 1.8 m) stop bar detection loops, the front of the loop should be placed 59 to 64 feet

(19.8 to 21.3 m) from the nearest edge of the through lane of the intersecting road extended.

When video detection is used, the video detection system shall be manufactured by Econolite

and shall be the Autoscope Solo Pro system. Typically, the video detector should be

mounted to the luminaire arm that is attached to the traffic signal pole. When video detectors

are used for advance detection, the video detectors should be mounted to the luminaire arms

of street light poles within close proximity to the intersection. The manufacturers

representative shall be consulted to determine the proper placement of the video cameras. In

addition to the video detectors, detection zones shall also be illustrated on the signal plan.

Service boxes shall typically be provided whenever conduit changes direction and adjacent to

signal poles and controllers. Junction boxes should typically be used adjacent to detector

loop locations for the splicing of loop wire to the lead-in cable. Type I junction boxes shall

be used where one or two conduit runs enter/exit the box. Type II junction boxes shall be

used where more than two conduit runs enter/exit the box. Service and junction boxes shall

be installed at least 2 feet (0.6 m) from the back of curb to the center of the box and no closer

than 2 feet (0.6 m) to any pole. The distance between service and/or junction boxes shall not

exceed 500 feet (150 m) to facilitate the pulling of cable.

All conduit for traffic signal installations shall be either Schedule 40 polyvinyl chloride

(PVC) conduit or Schedule 40 high density polyethylene (HDPE) conduit. Rigid metallic

conduit shall NOT be used. Signal conduit that extends from signal poles to adjacent service

boxes should typically be 3-inch (75 mm) conduit while signal conduit that extends from the

signal controller to the adjacent service box shall consist of two 4-inch (100 mm) conduits.

Signal conduit that extends from service box to service box should be either 3-inch (75 mm)

or 4-inch (100 mm) conduit, depending upon the number and size of conductors. Signal

conduit for advance detector conduit runs should typically be 1.5-inch (38 mm) conduit while

conduit for signal interconnect/fiberoptic cable should typically be 2-inch (50 mm) conduit.

Please note, street lighting cable is permitted in signal conduit runs and boxes. The conduit

sizes above are typical applications. The Engineer, however, shall verify that the signal

conduit is properly sized so that no more than 40 percent of the conduit cross-sectional area

is filled.

The Engineer shall coordinate and verify the location of the proposed secondary service point

with the appropriate utility company to ensure availability of service. A conduit with a pull

string shall extend from the controller to the secondary service point.

A 2-inch (50 mm) conduit shall be used when Kansas City Power & Light is providing the

power; a 3-inch (75 mm) conduit shall be used when WestStar is providing the service.

Controllers should typically be located adjacent to and behind the sidewalk or at least 10 feet

(3.0 m) from the back of curb to the center of the controller where no sidewalk exists. In

locations where no curb exists, the controller should typically be placed more than 10 feet

(3.0 m) from the edge of pavement to the center of the controller if possible. When thelocation of the controller has been finalized and power has been verified with the utility

company, the City will provide the Engineer with an address and an identification number for

each proposed controller. The address and identification number shall be placed in the lower

right corner of the traffic signal plan sheet above the titleblock.

The City has standardized the number of conductors required for the various types of traffic

signal equipment. Cable for vehicle signal heads should consist of 7-conductor cable while

cable for pedestrian and pushbutton detectors should consist of 5-conductor cable. Typically,

the City uses 1-7c per phase for the vehicle signal heads regardless of how many heads are on

the mast arm or the signal pole. When pedestrian heads and pushbutton detectors are used, 1-

7c cable should extend from the controller to the signal pole for the pedestrian head(s) on thepole and 1-5c should extend from the controller to the signal pole for the pushbutton

detector(s) on the pole. Detector lead-in cable should consist of 4-conductor cable while

detector loop wire should consist of single conductor PVC/nylon with tube jacket. Street

lighting distribution cable should consist of 3-1c No. 4 AWG while pole and bracket cable

shall be No. 12 AWG 2-conductor stranded copper conforming to IMSA Specification 19-1.

In addition, all street lighting cable for luminaires on signal poles should be spliced inside the

signal pole, not the service box adjacent to the pole. Fiber optic cable shall consist of a 72-

fiber cable assembly which includes 36 single-mode and 36 multimode-graded fibers.

The City has developed some typical signal timings and some guidelines that should be used

when developing timings for a proposed traffic signal. They are as follows:

Maximum Green to be determined by the City Walk 5 seconds Flashing Dont Walk distance is measured from the back of curb to the far side of

the traveled way and is then divided by 4 feet/second (1.2 m/s) to obtain the Flashing

Dont Walk time.

Minimum Green 6 seconds for through and left-turning phases. In cases wherethere are 6 ft. x 6 ft. (1.8 m x 1.8 m) detector loops at the stop bar and the approach is

on recall, 12 seconds of minimum green should be used.

Passage 1 second for through and left-turning phases Yellow should be determined using the methodology found in the latest edition ofITEsManual of Traffic Signal Design. For protected/permissive and protected left-

turn phases, use a 25 mph (40 km/h) speed limit for the calculations.

Red Clear should be determined using the methodology found in the latest editionof ITEsManual of Traffic Signal Design. For protected/permissive and protected

left-turn phases, use a 25 mph (40 km/h) speed limit for the calculations.

In Table 1 Phase Functions, information should be entered into the following function

categories:

Vehicle Recall typically the main street through phases Permit all phases in use Pedestrian Phases all phases in use Lead Phases typically left-turn phases Start-up Green typically the main street through phases

In the Emergency Flash table, the indications for all applicable signal phases shall be RED

while the indication for pedestrian phases shall be DARK.

In the Detector Input File Layout, the detector loops for the through phases on the main street

should typically be arranged in such a way that enables the City to count traffic. This is done

by arranging the advance detector loops in the Extend and Count slots of the appropriate

detector channel and inserting the stop bar loops in the Extend or Call slots.

In Table 4 Detector Map, the City typically adds a 10-second delay for loops in exclusive

right-turn lanes that are not on recall. The City also adds a 3-second delay for loops in left-

turn lanes that could be called when a left-turning vehicle on the adjacent approach crosses

the loop. Lastly, when 6 ft. x 6 ft. (1.8 m x 1.8 m) detector loops are used for stop bar

detection, the City typically adds a 1.2-second carryover to extend the green time for these

particular loops.

In the Signal Output File Layout, the City prefers right-turn overlaps to be programmed

instead of hard-wired. This is done by connecting the yellow and green arrows in the EdSignal Head to field terminals 105, 111, 114 and/or 120.

Overhead street name signs shall be mounted to the mast arms using Astro-Brackets. There

shall be a minimum of two brackets per sign placed no more than 3 feet (1 m) apart with a

maximum of 1 foot (0.3 m) from the edge of the sign. Typically, the overhead street name

signs should be placed between the signal pole and the first vehicle signal head.

PAVEMENT MARKINGS

All proposed pavement markings shall conform to the City of Lenexas Technical

Specifications. The table below illustrates the various types of pavement marking materialthat shall be used depending upon the age and type of the surface.

Stop bars should typically be placed 4 feet (1.2 m) in advance of and parallel to the nearest

crosswalk line. In the absence of a marked crosswalk, the stop bar should typically be placed

at the desired stopping point, but should be placed no more than 30 feet (9 m) nor less than 4

feet (1.2 m) from the nearest edge of the intersecting traveled way. When determining the

desired stopping point, turning templates for left-turning vehicles should be shown on the

signal plan to determine where the stop bar should be placed without interfering with a left-

turning vehicle on the adjacent approach to the intersection.

With regards to parking lots, pavement markings for parking stalls shall be white in color.

All other parking lot markings shall be in conformance with the MUTCD.

within 2 of the back of curb, except the supply line as it crosses the curb.

The designer shall coordinate the locations and components of the water line taps with theJohnson County Water District. Valve sizes for the supply line shall be the minimum size

sufficient to provide the required operating pressure. All material and work on the electrical

system shall meet the requirements of the National Electric Code, and/or the International

Building Code as adopted by the City of Lenexa, whichever is more stringent.

15. GRADING PLAN SHEET

(Required when cross-sections are not used. When the City funds the design of the

improvements, cross-sections will be required, and the Grading Plan Sheet is not

required.)

The Grading Plan Sheet shall be drawn at a scale of 1 = max 100 (1=10) [1=20(1=100), 1=50 (1=300), or 1=100 (1=10) are acceptable], with match lines for

multiple sheets when necessary, and shall include the following information:

Existing Topographic Features -- Trees, hedges, brush, buildings, pavement,utilities, fences, curbs, drives, sidewalks, inlets, manholes, valves, and other

manmade objects--shown in 1/2 tone

The current physical features (both natural and manmade) of the property andadjacent land within 50 (15M) include contours at vertical intervals of not

more than 5 (1M) where the slope is greater than 10% and not more than 2

(0.5M) where the slope is less than 10%. Elevations shall be marked on such

contours based on the existing datum plane established by the U.S. Coast and

Geodetic Survey. Include dates of topography and permanent and temporary

benchmark locations and elevations. (Information noted in this paragraph

shall be screened 50%.)

Proposed contours shown at the same contour interval as the existingcontours

Lot and subdivision lines with lots and blocks numbered per the plat of thesubject subdivision

Street centerline alignment with edge of pavement lines, edge of sidewalklines, and back of curb lines

North arrow and bar scale

Street names, R/W lines, easements--existing and proposed--(show centerlineand limits of the easements)

Plan sheets do not necessarily need to be in the same order as presented above, but must

contain all of the sheets listed unless otherwise stated in the sheet description.
