CENTENNIAL VALLEY DESIGN GUIDELINES
<br />Introduction
<br />The Centennial Valley Design Guidelines are established herein to set an overall
<br />direction and basis for the quality of the development. Concurrently, the guidelines
<br />will aid the city, builders, and developers in meeting the goals of the project and will
<br />ensure the protection of property values.
<br />Creative and innovative designs for the project are encouraged. To stimulate such
<br />design, the City will accept proposals for variances in its subdivision and development
<br />standards. For example, in cluster housing areas, street widths may be reduced, or for
<br />alternative pedestrian circulation patterns, sidewalks or streets may be eliminated.
<br />Likewise, building heights, setbacks, and other zoning controls may be altered in
<br />response to creative design.

<br />CENTENNIAL VALLEY DESIGN GUIDELINES
<br />SINGLE FAMILY RESIDENTIAL PARCELS 3, R, and Q
<br />The intent of the Design Guidelines for Single Family Residential Parcels is to
<br />specifically outline those items that will be addressed by the Developer during the
<br />development plan approval process for Parcels 3, R, and Q, as deliniated on the
<br />Centennial Valley General Development Plan. Each parcel will be developed in_
<br />compliance with all local ordinances and design criteria. (See Appendix A: Guideline
<br />Illustrative for Single Family Development)
<br />1.
<br />TRAFFIC PATTERNS AND INTERNAL ROAD CONFIGURATIONS
<br />A. Internal road configuration will encourage local traffic only and minimize
<br />through traffic.
<br />B. For safety and aesthetic reasons, straight street runs shall be minimized.
<br />C. A minimum of two vehicular access points from the subdivision to the
<br />major arterial or parkway shall be provided for convenient local traffic and
<br />public safety needs.
<br />D. Any internal hike/bike trails shall be integrated and compatible with the
<br />City of Louisville Master Trail System.
<br />E. Cul-de-sacs shall serve no more than 30 single family lots.
<br />F. Street widths should reflect street hierarchy as well as respond to the
<br />functional character of each street.
<br />2. LANDSCAPING AND OPEN SPACE
<br />A. Entry islands will be provided when accessing arterial streets and will be
<br />landscaped according to the City of Louisville Landscape Design Guidelines
<br />for Medians and Public Rights -of -Way.
<br />B. When compatible with the character of the proposed subdivision and if cul-
<br />de-sacs are part of the site design, landscape islands will be landscaped in
<br />accordance with acceptable local practices and in compliance with City of
<br />Louisville Landscape Design Guidelines.

<br />CENTENNIAL VALLEY
<br />GENERAL DEVELOPMENT PLAN
<br />C. Open space in the Single Family Parcels shall be treated as a positive
<br />element and designed accordingly, for either passive or active use or both.
<br />Careful consideration shall be given to integrating these areas with other
<br />open space within the parcel as well as the overall open space system of
<br />the development.
<br />D. Screening shall be provided when units are adjacent to arterial streets in
<br />order to abate noise impacts and to screen potential unsightly views.
<br />Examples of appropriate screening materials include the following:
<br />• Fences
<br />• Dense shrubs
<br />• Walls
<br />• Evergreen trees
<br />• Earth berms
<br />3. LOT CONFIGURATION AND DESIGN
<br />A. Lot configuration and design shall reinforce the identity and character of a
<br />single family subdivision. To encourage flexibility in design, specific lot
<br />sizes will be established at the site plan approval stage.
<br />• The intended minimum lot size may be approximately 4000 square
<br />feet
<br />B. The design of each parcel shall maximize exposure to open spaces within
<br />the parcel or to exterior active park areas whenever possible.
<br />• Clustering of single family attached and detached units is encouraged
<br />in order to create additional open space.
<br />C. In parcels designated for single family development, up to 20% of the
<br />allowable unit density may be built as attached single family units.
<br />• No more than six units may be attached in one building.
<br />D. Residential lots will be designed to front on local streets, and preferably
<br />cul-de-sacs and/or courts.
<br />• Lot frontage on collectors, arterials, and parkways will not be
<br />permitted.
<br />• Double frontage
<br />not permitted.
<br />lots which orient to collector streets are
<br />E. Lot orientation will encourage energy conservation and use of solar energy
<br />when possible and when compatible with existing topographic and arterial
<br />access.
<br />F. Inhabitable structures will not be constructed in the flood plain.

<br />4. SUBSIDENCE
<br />A. Appropriate engineering studies will be done to determine if any subsidence
<br />potential exists. All reports will be submitted with the respective
<br />development proposals.
<br />5. BUILDING HEIGHTS, LOT COVERAGE AND SETBACKS
<br />A. Varied front setbacks are encouraged in order to provide visual relief and
<br />to reinforce the single family character of each neighborhood.

<br />usable outdoor space.
<br />C. Minimum setbacks and maximum heights and lot coverage requirements for
<br />conventional detached single family residences may be according to City of
<br />Louisville Standards. However, in order to encourage flexibility and
<br />creativity in site planning and building design, alternative requirements
<br />shall be considered in cases which incorporate innovative or high quality
<br />site planning and architectural design (such as clustered, attached, or zero
<br />lot line residences).
<br />The alternative requirements are the following:
<br />Front Lot Line 10 feet or a minimum of 20 feet

<br />20 feet minimum for collector
<br />streets
<br />Interior Lot Line 0 or 3 feet minimum
<br />Height of Principle Use
<br />35 feet maximum (measured from
<br />the average elevation of the finished
<br />grade along the front of the
<br />building to the highest point of the
<br />roof)
<br />Lot Coverage 40% maximum of total lot area
<br />6. PRIVATE DRIVES AND PARKING
<br />A. Individual driveways for corner lots shall be located as far as possible from
<br />street intersections.
<br />B. Offstreet parking for two vehicles shall be provided for each unit.
<br />C. To alleviate problems with snow/ice build-up, the drive ways with north or
<br />east orientation will not exceed a slope of 5%.
