6/63


Standards & GuidelinesThese standards and guidelines apply to new development andredevelopment within the Lenexa City Center Neighborhood.Developers are strongly encouraged to meet with City staff duringthe schematic design phase of a project or building to discuss theapplicable design standards and guidelines. All concept plans,preliminary plans and final plans shall be evaluated for conformance

with the design standards and guidelines. In addition, each project, inconjunction with the approval of the projects development agreementwith the City and plan, is expected to have its own set of specific designstandards and guidelines that may address, in more detail, elementssuch as building materials, colors, pedestrian lighting, street furniture,awnings, signage, building lighting, landscaping, and artwork. Mixed-use buildings are strongly encouraged throughout all projects.

The design standards & guidelines in this document are to be usedin conjunction with the other regulatory requirements of the CC, CityCenter Zoning District. The text of each Section indicates whether theproposed criteria are guidelines or standards. Guidelines (should)are advisory, but strongly recommended; and standards (shall) aremandatory. In addition, each subsection contains an Intent Statement.This is a broad statement explaining the design intent for the standardsand guidelines that follow. They should be used to help interpret theapplication of a standard in a specific situation. In cases in whichspecial conditions exist that are not specifically addressed by thestandards and guidelines, the intent statement should serve as the basisfor determining the appropriateness of the proposed design.

Street Classification System And Standards

The street classification system applies to streets within theLenexa City Center neighborhood. The Guidelines thatfollow are meant to serve as a general guide for streetdesign. The overall design and functionality of eachstreet should be in the context of creating a unique urbanenvironment for adjacent land uses and the people who use

them. Traffic, pedestrian, stormwater, building and othercompeting design needs must be properly balanced toachieve an appropriate urban form for each street. Somevariety (e.g. one-way streets, angled parking, medians,etc.) in street design and on-street parking configurationsis encouraged to create a special sense of place withinCity Center. The following are illustrations depicting thecomponents of each street type and selected applicablestandards.

Variations in Building Design

Intent:

For developments containing three or more buildings, particularly larger residentialdevelopments, the purpose is to create a range of different forms and designs sothat repetition and monotony are avoided.


1. Buildings within a development should not use identical footprints, elevations,materials or color. While there may be some elements that provide acommonality to the entire development, variety shall be visually evident.

2. Although it is recognized that some repetition is needed to achieve economies

of scale, the design shall nevertheless use various techniques to producebuildings of differing, but related, character. This will require some buildingsto be of a different size, shape, and orientation. Colors and materials shouldbe recombined and used in different ways to achieve this variety.

3. No more than two identical structures shall be adjacent to each other oracross a street, lane or parking area.

4. A palette of materials and colors shall be provided by the Developer that showsthem in proportions relative to the proportions used in the development. Trim,for example, shall be shown as a comparatively small proportion to siding.In addition, elevations rendered in color shall be provided, however, if thereare building designs that do repeat, these can be shown as types.

5. Buildings within the City Center should be designed for this place as a distinctlocation and should not be standard templates.

APPENDIX A: City Center Neighborhood Streetscape Elements M

The following Streetscape DesignMatrix is an addition to the City CenterNeighborhood Design Guidelines andwas created to ensure that the principlesof urban place making were encouragedwithin the proposed street corridors. These

principles have been identified as:

Walkability

Mixed Use

Connectivity

Compactness

Sustainability

Community

Incorporating these principles into thecreation of the Streetscape Design Matrixresults in a better understanding of where thelinkages between all of the neighborhooddevelopments will occur within Lenexa CityCenter, and reinforces these principles byguiding the selection of unifying streetscapeelements.

The street is the river of life of the city, the place where we come together, the pathway to thecenter.

- William H. Whyte

STREETSCAPE ELEMENTS MATRIX


48/63



Methodology:

The vision for overall connectivityand unifying elements, to beplaced at the pedestrian level,is desired for the City Centerneighborhood. This approachhelps promote the future

developments to become thewalkable urban environmentseveryone wants them to be.

These elements also allow forthe identity of Lenexa to crossindividual site boundaries andemerge as a unified City Center.The proposed unifying elementsthat have been delineatedinclude:

Roadway Lighting

Pedestrian Lighting

Site Furnishings

Tree Species

The diagram above delineates three specific corridors that extend across87th Street Parkway and Renner Boulevard and will reinforce a higherlevel of connectivity at the pedestrian level. The Red, Blue, and Greenstreets represent where the primary unifying elements should occur.

Street Hierarchy:

The overall hierarchy that wascreated for the City Center included three major vehicular/pedestrian corridors that extended across site boundaries as welas Renner Boulevard and 87th

Street Parkway. These streetsare graphically represented asthe Red, Blue, and Green Streetsin the diagram at left.

The Blue Street is the main connector street between the CityCenter East Village and CityCenter development.

The Red Street is the innecirculation ring that currentlyconnects City Center EasVillage, City Center, and City

Center North Village.

The Green Street is the mainNorth/South connector streethat links the City Center NorthVillage and the City Center development.


49/63



The Streetscape Design Matrix delineates the unifying elements that will be required throughout the various phases of devel-opment within the Lenexa City Center Neighborhood. The matrix will link the major streets within the Lenexa City Center byproviding a palette of contiguous site furnishings, street trees, and pedestrian lighting. The repetition of a palette of visuallycohesive urban elements creates a unified pedestrian district and a more cohesive design. The matrix should be used as areference to the following pages, which contain product specifications of the selected streetscape unifying elements.

Street Trees - shall be located a minimum distance of 2.5 from back of curb to center of tree. The Director of Planning shall approve proposed tree species for all

other streets. Technical specifications for any of the proposed products may be obtained from the City of Lenexa upon request.

PEDESTRIAN LIGHTING AND BOLLARD DESIGN:

A unifying pattern of pedestrian lightfixtures and illuminated bollards willfurther add to the connection withinthe Lenexa City Center neighborhood.Well chosen light fixtures are anaesthetic benefit during the day and

night, as well as improving the safetyof the pedestrian way during the nighthours. Bollards that are limestone inappearance shall be incorporatedinto each project. The technicalspecifications provided by the City ofLenexa upon request.

LUMINIS ECLIPSE - W705 POLE MOUNT

The Luminis Eclipse W700 pole mount series offers dif-fused and controlled lighting, and is ideal for open pe-destrian landscapes. The Eclipse fixture and pole shallbe champagne (tan/brown) in color.

ROADWAY LIGHTING:

The street lights for Lenexa City Centerwere selected on the basis of function,maintenance, and overall aestheticsin a manner that helps unify the entiredevelopment.

The Gardco Circa pole mount series offersdiffused and controlled lighting, andis ideal for roadway applications. TheCirca fixture offers a LED ring around thefixture itself and is planned to be utilizedalong Renner Boulevard and 87th StreetParkway as well as other neighborhoodstreets. The blue LED ring will be utilizedfor those fixtures on 87th Street Parkwayand Renner Blvd. Each individual CityCenter project will select its own LEDring color. City Center East Village willalso be using the Blue LED ring. These

fixtures, when used on residential streets,shall not incorporate the LED ring.These fixtures and poles shall also bechampagne (tan/brown) in color. Thetechnical specifications provided by theCity of Lenexa upon request.
