Downtown Public Improvements Design Standards 2
CHAPTER 1: Introduction
Overview
In 2008 the City Council adopted the Citv of Lubbock Downtown
Revitalization Action Plan (CBD Action Plan) to articulate the
preferred vision for the revitalization process. The CBD Action Plan
was shaped after extensive citizen input through a collaborative
effort between the urban design consulting firm EDAW, Inc. from
Denver, Colorado, the economic development firm Development
Strategies of St. Louis, Missouri, local design firm Parkhill, Smith,
and Cooper, Inc., and the City of Lubbock. The Planning
Department adjusted the boundaries of the plan areas slightly to
coordinate with existing and proposed zoning in downtown
Lubbock. See Figure 2: Downtown Revitalization Action Plan (CBD
Action Plan).
While the CBD Action Plan provides a vision for Downtown, more
specific technical guidance is needed for a coherent, unified
Downtown design. This publication is just one of several documents
needed to guide that design.
The primary mechanism for private sector redevelopment is the
Central Business (CB) Districts of the City of Lubbock Zoning
Ordinance. The Lubbock City Council, on the recommendation of
the Planning and Zoning Commission, adopted six zoning code
districts into the Zoning Ordinance that provide for the specific
needs of different areas of Downtown, including those identified in
the CBD Action Plan.
Like other sections of the zoning code, each CB Zoning District
includes standards for height and building orientation, building mass
and scale, parking areas, and landscape areas. Each of the CB
Zoning Districts fully adopts the Design Standards.for the Central
Business District (CBD Design Standards) within the ordinance to
provide more detailed design standards for new construction and
rehabilitation projects. The standards provide a mechanism for
review and approval of construction and remodeling plans within the
CB Zoning Districts, including an appeals process.
This document, Downtown Public Improvements Design Standards
(Public Improvements Standards), serves as the second guide for
development. While the CB Districts and the Design Standards for
the Central Business District that are incorporated within them
govern private property within the CBD, they also include
requirements for parts of the public right-of-way. The Public
Improvements Standards does not replicate the requirements of the
CB Ordinances, but sets a minimum standard for all right-of-way
improvements in the area.
The Public Improvements Standards provide a basic design concept
for right-of-way improvements in downtown Lubbock that can be
used by the City and by private developers of Downtown property.
These public improvements will create a desirable environment for
downtown life while providing a framework for private
development. This document will apply within the boundaries shown
on Figure l: Public Improvements Standards Boundary.
Rebuilding the right-of-way improvements of downtown Lubbock
generally will follow the pattern of private development. The Public
Improvements Standards apply to all projects within this area,
whether privately funded by developers of adjacent property, or
publicly funded by the City of Lubbock or any other governmental
entity.
Downtown Public Improvements Design Standards 3
Using the Downtown Public hrrproventents
Design Standards
Developers proposing projects in Downtown Lubbock will have a
pre -application conference with the City of Lubbock Director of
Planning. Prior to the issuance of a building permit or completion of
a developers agreement, the Director of Planning, in consultation
with the Director of Parks and other City staff members, will
determine if the proposed project meets the intent of the CBD Action
Plan, the City of Lubbock Zoning Ordinance and its CBD Design
Standards and the Public Improvements Standards. If the project
meets the ordinance or standards criteria, the project can proceed
through the City's normal building permit process.
If the Director of Planning determines that a proposal contains
unique circumstances the Director may make minor amendments to
accommodate the Public Improvements Standards if ratified by the
CBD Tax Increment Financing Reinvestment Zone (TIF)
Developemnt Sub -committee. Any appeal of the Director of
Planning or major changes will be relerred to the Urban Design and
Historic Preservation Committee (UDHPC) for review. Upon
recommendation of the UDHPC, the Director of Planning may vary
the requirements of the Public Improvements Standards so long as
the basic requirements of the Zoning Ordinance or any other
applicable codes are not altered. Any variations from City codes will
follow the review and appeal process outlined in that code.

CHAPTER 2: Design Concepts
Downtown Lubbock is distinguished by the presence of historic
buildings and materials as well as the large scale of buildings at the
street level. As the area returns to serving as a center for living,
working, and recreation, this urban character will be maintained
through the use of historical elements and appropriate building scale.
Although each of the CB Zoning Districts has unique needs and
opportunities for redevelopment, the following right-of-way
elements will be coordinated throughout Downtown Lubbock. Street
furnishings are a fundamental component to the success of the street
and neighborhood. Furnishings allow places to sit, deposit trash, and
secure bicycles. Beyond the functional benefits, the right furnishings
can attract and engage the public by creating a safe, comfortable, and
welcoming environment.
Historic Brick Pavers
Many of the streets in Downtown Lubbock are paved with fired clay
brick pavers. These streets were built during the 1920's and 1930's
primarily by the City of Lubbock but some by New Deal public
works programs. Many of the historic brick removed in
reconstruction projects have been stored for future repair,
reconstruction, and use in special projects. Consideration should be
given to using these bricks in projects if possible. Property owners
and developers should coordinate their requests with the City of
Lubbock to verify current quantities and sizes available in advance
of designing or constructing their projects.
In 2006, the City Council adopted City code revisions that protect
existing brick streets in most cases. Ordinances were amended to:
Provide continued protection of brick streets and alleys by
requiring appropriate repairs as outlined in the 1982
resolution and the repair details prepared by Streets
Engineering.
Specify that all bricks salvaged from any removal or repair of
streets will remain the property of the City of Lubbock.
Specify a review process for removal that allows Urban
Design and Historic Preservation Commission (UDHPC)
determination with appeal to the City Council, using the
same concept of review and appeal that currently governs
Lubbock Historic Landmark Certificates of Appropriateness.
Requirements for the repair and maintenance of brick streets are
addressed in the City of Lubbock Code of Ordinances in Section
36.07.011 Brick Streets, Section 36.08.006 Brick Alleys, and Section
40.03.3224. The UDHPC has made recommendations for continued
preservation and improvement of brick streets. See Figure 3:
UDHPC Recommendations for Historic Brick Streets.

Specialty Paving
Sidewalks and related pavement elements such as crosswalks direct
movement, define space, and provide for pedestrian safety.
Enhanced pedestrian crossings at intersections will facilitate
pedestrian movement and help slow traffic. Specialty paving adds
visual interest and articulates special landscape features.
In Downtown Lubbock, differing patterns and materials will identify
and separate the different spaces of the sidewalk environment.
However, sidewalk surfaces should present a consistent and unifying
element in the district. Sidewalks will be built to existing City of
Lubbock construction standards, though the Lubbock Building
Board of Appeals can consider alternate styles.
The approved brick pavers for sidewalk and crosswalk
enhancement are the Pavestone Holland Stone Parkway Series
(non -chamfered edges) in the Antique Buff, Antique Red, or
Antique Terra Cotta color patterns or equivalent as approved by
Director of Planning.
Subject to landscape plan review, this series may be used in
sidewalk projects encompassing one full block face or more.
Selected concrete pavers should comprise at least 50 percent of
the sidewalk surface area. See Figure 7: Corridor and Gateway
Parkway
The clear pedestrian path of the sidewalks should be at least 5'
wide when the total parkway width is less than 10' wide, with the
remaining width serving as the amenity zone. If the total
parkway width is 10' wide or greater, the sidewalk should be 50
percent of the width of the total parkway, with the remaining
width serving as the amenity zone as approved by Director of
Planning.
• Paver patterns should be consistent within sidewalk spaces by
block, for example, one pattern for the primary walkway and one
pattern for the hardscape apron between tree grates. Sidewalk
design and materials will be approved as part of the permit or
contract review process.
• Approved paving patterns are Harringbone, Parguet, and Runner
Bond. Please see the following three (3) examples of each.

*Please note the Stack pattern is not approved.*
• Specialty paving may be used to extend the sidewalk visually
across the street at selected gateway and corridor intersections.
All crosswalks shall be approved concrete pavers with concrete
banding. No historic brick surfaces will be disturbed to create
intersection paving features. All four sides shall be updated at
once.
Exposed aggregate concrete is not an approved paving surface for
redevelopment in the Central Business District.

Specialty Vehicular and Pedestrian Lighting
Lighting is important both for safety and for the ambiance of the
neighborhood. Pedestrian level lighting further reinforces the human
scale of downtown Lubbock and encourages outdoor activity.
In the Downtown area, specialty lighting fixtures have been selected
to provide a unique identity for the area. Two levels of lighting poles
have been selected to provide flexibility in the public right-of-way:
a medium pedestrian light standard and a tall vehicular or roadway
lighting standard.
• Specialty vehicular lighting will be included in all streest within
the Downtown Public Improvement Standards boundary as
identified in Appendix A: Vehicular and Pedestrian Lighting
Specifications.
• Specialty pedestrian lighting is required on all gateway and
corridor streets and for any projects encompassing a full block
face or more and may be installed for smaller projects if
approved in the landscape plan review.
• Vehicular and pedestrian lighting is specified in Appendix
A: Vehicular and Pedestrian Lighting Specifications.
• A lighting plan will be submitted to and approved by the City of
Lubbock on all projects where lighting is required or proposed in
the right-of-way.
• Pedestrian lighting shall be tied to street lights for power.
The following general conditions will apply in every area where
specialty lighting is used. More detailed information is included in
Appendix A: Vehicular and Pedestrian Lighting Specifications.
• Lighting will include full cutoff or cutoff lighting fixtures as
defined by the Illuminating Engineering Society of North
America (IES).
• All new vehicular and pedestrian lighting shall be LED to
provide a white -colored light that is excellent for color clarity.
• Pedestrian lighting will be spaced evenly along the block in
relationship to each other and to the street centerline. Across the
street relationships should also be considered, as well as spacing
to provide illumination at alley intersections.
Vehicular lighting will be placed at every intersection, with at
least one additional light at mid block.
Downtown Public Improvements Design Standards 11
Public Parks, Plazas, and Features
Several parks and open spaces have been proposed in the CBD
Action Plan to serve the public by providing green spaces. These
spaces will serve as anchors for the proposed districts. Designs for
these public spaces shall conform to these standards and specific
plans will be reviewed under the process outlined in this document.
Public Art and Banners
Public art is a major component in enhancing a community's visual
image. In Downtown Lubbock, sculpture, architectural trellises,
pavilions, and similar symbolic structures will add interest to public
parks, plazas, and squares. Many of these elements have already
been implemented in various parts of Downtown and new works
should complement existing art. In addition, banners from vehicular
light standards on gateway and corridor streets will add to the urban
ambiance of Downtown.
Any proposed art work or banners in the public right-of-way shall be
submitted to the City of Lubbock for consideration and approval
before the work is installed. Artwork and banners will meet all
Zoning Ordinance requirements, be approved by the Planning
Department, and may not conflict with the sign code. Such artwork
and banners may not have a business name included, nor be an
artistic expression of the particular type of business on the parcel.
Street Signage
Street signs, stop signs, parking signs, directional signs, and
informational signs will be coordinated to establish a unified
appearance within the Downtown area.
• Signage should be placed to ensure a clear pedestrian pathway
without restricting visibility at intersections
• The City of Lubbock shall provide a decorative logo on street
sign toppers as approved by the Downtown TIF Board.
• Signs shall be installed in a visually pleasing manner that
coordinates with the rest of the street amenities. However, all
devices will be installed in accordance with the latest edition of
the Texas Manual on Uniform Traffic Control Devices
(TMUTCD).
Utilities
City of Lubbock Resolution 2011-R0287 adopted on July 14, 2011,
noted that "among the goals and objectives of the Downtown
Revitalization Plan were the goals of reducing the fragmentation of
blocks caused by bidirectional alleys, [and] working with utilities to
consolidate and co -locate physical infrastructure located in these
alleys." In adopting this Resolution, "City Council has determined
that it is reasonably necessary for all utilities located overhead in the
streets and alleys of the Downtown area to be relocated into an
underground duct system as this public improvement is installed by
the City of Lubbock" and provided a mechanism for notification of
utility relocation.
The City's intent is to keep the alleys and pedestrian area of the
right-of-way clear of utility obstructions, including poles and control
boxes. The pre -application interview with the Director of Planning
will include discussion on the requirements for underground utility
placement and positioning and relocation of above ground
obstructions into the City -installed underground duct system.
Public and private utility services should be placed to avoid trees and
not to disrupt their alignment or spacing. Special attention must be
paid to preserving visual access at comers for pedestrians and
motorists. Utilities should be placed before any right-of-way
improvements are made.
Downtown Public Improvements Design Standards 12
Traffic signal boxes, transformers, telephone switching boxes, or
other utilities that cannot be located underground or accommodated
by easements on adjacent private property should be located away
from building entrances and main views within the right-of-way.
Any utility boxes that are visible in the right-of-way shall be flat
black or forest green.
Benches

CHAPTER 3: Gateway and
Corridor Streets
Introduction
During the initial studies of downtown Lubbock, a framework for
improvements was established by first identifying the main gateway
and corridor streets that define the area. Gateway features, specialty
paving, landscaping, street furnishings, and banners on light poles
will serve as unifying elements and contribute to the ambiance of
gateway and corridor streets. See Figure 5: Gateways and
Corridors.
The gateway streets include the portions of Avenue Q, 191h Street,
Broadway, Buddy Holly Avenue, Mac Davis Lane, Glenna
Goodacre Boulevard, and Avenue L shown on Figure 5: Gateways
and Corridors. Avenue J, 15h Street, and 161h Street are corridor
streets connecting different areas of Downtown. Since 191 Street and
Avenue Q are under the jurisdiction of the Texas Department of
Transportation, any improvements on those streets must be approved
by and coordinated with the Lubbock District office.
Certain amenities will be limited to gateway and corridor streets.
Street furnishings will be spaced along each block, including three
benches, a trash receptacle, and two bicycle racks per block face.
Specialty vehicular lighting where banners can be displayed will
help define the special nature of these streets. Banner locations will
be limited to these streets. Unique pedestrian crossings, including
specialty paving, will add to the character of the street by further
defining intersections and promoting pedestrian safety.
Markers and monuments create a sense of arrival into downtown
Lubbock as well as transition between districts. Such features give
the first impression of a place. Downtown Lubbock has several
identified gateway points that will require a special treatment.
Recommended locations of gateway features are indicated on Figure
Gateways and Corridors.
Traffic Impact
Any development that expects to generate high Average Daily
Traffic (ADT) or high traffic due to regularly scheduled events shall
be required to conduct and provide the City of Lubbock with results
from traffic studies. The traffic studies should show analysis with
current street layouts or proposed street modifications. Current and
future impacts to downtown Lubbock's pedestrian, vehicular, and
transit circulation should be considered in the traffic analysis.

Downtown Public Improvements Design Standards 17
Gateway Streets
Gateway streets are the major streets into downtown Lubbock and
the introduction to Downtown for most travelers. See Figure S.
Galewav and Corridors. These streets typically have a higher
volume of vehicular traffic. Because of their higher traffic carrying
capacity, gateway streets should have less frequent vehicular access
points or curb cuts. The size and number of vehicular access points
or curb cuts per site development on the Gateway and Corridor
streets will be coordinated with City of Lubbock staff for approval.
Broadway
Broadway has historically been the spine of the Central Business
District, linking the entrance to Texas Tech University and
downtown Lubbock. In 1995, improvements on Broadway between
University Avenue and Martin Luther King Boulevard were
completed with a major Texas Department of Transportation grant.
Pedestrian and vehicular lighting, street trees, and specialty paving
were early efforts to establish an urban design theme for downtown
Lubbock.
Some changes will be needed to unify Broadway's existing
enhancements with those proposed for the rest of the CB -2 Zoning
District. Any redevelopment of property along the Broadway
corridor will be required to match the style and design of the existing
corridor as best possible with additional requirements of required site
furnishings as per this document.
Buddy Holly Avenue
Buddy Holly Avenue is already established as the gateway to the
Depot District. It also serves as a corridor through the Central
Business District, terminating at IH 27 on both the north and south.
The Buddy Holly Avenue right-of-way measures 100 feet between
property lines. This expansive width allows for multiple lanes of
vehicular traffic, tree -lined streets, and on -street parking.
Mac Davis Lane
Mac Davis Lane is a gateway into the Memorial Civic Center and
Arts District from Avenue Q. A special treatment is necessary to
distinguish arrival into these special zones. Additional trees located
on properties adjacent to the right-of-way will create a park -like
setting within the Civic Center district.
Glenna Goodacre Boulevard
During the redevelopment of North Overton, Glenna Goodacre
Boulevard was designated as the central spine through that
neighborhood. Extending the Glenna Goodacre improvements across
Avenue Q to Avenue O will enhance the entry to the Civic Center.

Downtown Public Improvements Design Standards 18
Corridor Streets
Corridor streets serve as the crucial links between districts within
downtown Lubbock. The most important of these is Avenue J, which
has been identified as the best link between the Depot District and
the Arts District. Similarly, portions of 151h Street and 161h Street will
serve as corridors within the Depot District. Special street conditions
are necessary for such corridors in order to accommodate pedestrian
activity. The identified gateway streets mentioned previously will
also serve as corridor streets.
Avenue J
Avenue J will serve as the link between the Depot District and the
Arts District. Avenue J was proposed in the Central Business District
Action Plan to become a ground -floor retail corridor. It is important
that Avenue J shall be developed as a pedestrian friendly retail
corridor with limited parallel parking directly on Avenue J.
The Avenue J right-of-way measures 75 feet between property lines.
This presents a complex design challenge as the corridor must allow
for pedestrian and cyclist activities, street amenities and plantings,
outdoor dining spaces, and lanes for medium -level vehicular traffic.
Avenue J is proposed as the main retail spine downtown between the
Depot District and the Arts District, it is important that the right-of-
way improvements within this corridor promote a pedestrian -friendly
environment.
Removal of existing angled parking along Avenue J will provide
additional area for pedestrian traffic. An increased level of
pedestrian seating will accommodate outdoor activity. Additional
trash receptacles will ensure the cleanliness of the corridor and extra
bike racks will promote transportation by bicycle.
15th Street & 16th Streets
15h Street and 161 Street between Avenue J and Crickets Avenue
are also corridor streets with the Depot District and will receive a
similar treatment to Avenue J.
Downtown Public Improvements Design Standards 19
CHAPTER 4: Landscaping
General Landscaping
The following general landscaping standards apply to all public
right-of-way in the Downtown area and are to be used as a
supplement to the existing requirements for right-of-way
maintenance in the City of Lubbock Zoning Ordinance. Lubbock has
a semi -arid climate with a limited selection of native plant material
that can thrive on the small amount of annual rainfall received.
Therefore, it is in the best interest of the City to pursue landscaping
enhancements which promote water conservation.
When a private developer initiates a project in Downtown, a
landscape plan will be submitted as part of a building permit request.
During zoning review, the Director of Planning will coordinate
review of the landscape and irrigation plan with the Director of
Parks.
• Coordination of any landscaping shall be done as to not
interfere with existing pipes and utilities.
All plant material planted in the public right-of-way,
including trees, will be irrigated. Permanent, automatic
irrigation systems will be installed and tested prior to the
installation of any plant material. Irrigation systems will
utilize drip irrigation, subsurface irrigation, or other water -
conserving methods or technologies where possible.
• Irrigation shall be maintained and paid by the landowner.
The use of a hose bib for irrigation in the public right-of-way,
as allowed elsewhere in the Zoning Ordinance, shall not be
allowed within the area included in the Public Improvement
Standards.
A balance of trees, shrubs, ornamental grasses, and
groundcover is encouraged. Climatically -adapted plant
species should predominate for hardiness in urban conditions
and to minimize maintenance. See Appendix B.• Plant
Materials for a list of selected plant materials for the
Downtown area.
Trees, shrubs, ornamental grasses, and groundcovers of the
same species should be massed in groupings. Individual
plants should only be planted when the intent is to highlight
the species due to its unique color or form. Plantings with
similar watering patterns will be grouped within the proper
irrigation zones.
The use of flowering or brightly colored foliage creates color
and interest. Seasonal color is encouraged as an accent to
permanent bed plantings.
The use of raised planters is highly encouraged to make
plantings visible and easier to maintain where foot traffic is
dense or parkway width is limited.
Planting beds shall be dressed with a minimum of 1.5 inches
of "Jog Blend" limestone screenings mulch from R.E. Janes
Gravel Company, Slaton, Texas, or equivalent, or as pre -
approved by the Director of Planning or 3 inches of shredded
cedar bark mulch to retain soil moisture, establish healthy
root systems, and reduce weeds.
The use of shade trees is encouraged in and around surface
parking lots, streets, and other large areas of paving.
Deciduous trees on the south and west sides of buildings and
public use areas add shade in the summer and allow filtered
light in the winter.
Downtown Public Improvements Design Standards 20
Turf will only be used in low-density residential parkways,
single-family yards, public parks, and open spaces exceeding
400 square feet in the CB -3 Zoning District.
• Trees in or adjacent to the right-of-way will be trimmed so
that foliage is less than 80 inches above the top of curb of the
adjacent street. Plant materials other than trees in the right-
of-way may not exceed 2 to 3 feet in height as required by
the Lubbock Code or Ordinances, Section 40.03.212. See
Figure I/: View Obstruction.

Street Tree Framework
Street trees are inviting and help define major gateways and
corridors in the Downtown area. They soften the edges where
buildings meet the street, offer shade to pedestrians, and help cool
the pedestrian environment.
In order to establish a consistent design concept for public spaces in
the Downtown area, Figure 9: Street Tree Framework Plan, specifies
the specific tree species for each street and at each intersection.
Trees will have a minimum 4 inch caliper as measured by ANSI
standard nursery practices.
The following general street tree standards apply to all streets or
adjacent properties undergoing improvements and should be used
with Figure 9: Street Tree Framework Plan in developing landscape
plans.
• Street trees are required on all streets or adjacent properties
undergoing improvements. Space trees a maximum of 60 feet
on center along a street block with allowance for variations in
spacing for curb cuts, alleys, and drives.
The 60 foot spacing is derived from the historic block
dimension of most Downtown blocks being approximately
250 feet square with 20 foot alleys in the center for a total
block dimension of 270 feet. One tree per every 60 feet
should allow for an approximately 45 foot clear zone from
the property line comers of each block and five subsequent
trees in the midblock zone per historic 270 feet of block face.
See Figure 10: Typical Block Spacing Diagram.
Trees shall be aligned and in straight rows, parallel to the
curb. Ideally, trees will be centered in the space in which they
are planted but need to line up down the continuous length of
the street when possible. Align trees across the street and
space them evenly along the block in relationship to each
other and to the street centerline where possible.
Adjustments can be made for blocks not having the
traditional dimensions, but tree spacing should be kept
proportional. Where blocks have been consolidated, this
spacing should be maintained as closely as possible to
coordinate with spacing throughout the remaining Downtown
area. See Figure 10: Typical Block Spacing Diagram.
Existing trees and their root systems should be protected
during construction through the use of barricades and
fencing.
• Tree grates are required for trees in the right-of-way in all
zoning districts except C13-3. Tree grates provide for the
required exchange of water and oxygen for tree roots while
still providing a navigable surface for pedestrian walking. See
Tree Grate Detail, Page 14.

Appendix A: Vehicular and Pedestrian Lighting Specification
Lighting is important both for safety and for the ambiance of the neighborhood. Pedestrian level lighting further reinforces the human scale of the
neighborhood and encourages outdoor activity. Two levels of light standards have been selected to provide flexibility in the public right-of-way:
a medium pedestrian light pole and a tall vehicular or roadway lighting pole. In addition, a coordinating wall -mounted fixture is provided for use
on private properties adjacent to the right-of-way. All lighting shall include full cutoff and cutoff lighting fixtures as defined by the Illuminating
Engineering Society of North America (IES), and all vehicular and pedestrian lighting in the Downtown TIF District shall be LED to provide a
white -colored light that is excellent for color clarity.
Vehicular lighting poles on Gateway and Corridor Streets identified in Chapter 4 will include both inserts spun into the standards for banner
arms.

Pedestrian and Vehicular Lighting Spacing Pedestrian and Vehicular Lighting Exception for Residential
Vehicular lighting should be placed at every intersection
with additional lights the greater of at least one per mid
block or one per every 125 feet of continuous block length
along each block face. Vehicular lighting at intersections
should include two lights per intersection on diagonally
opposing comers. Preferably, all intersection lights will be
on the southwest and northeast comers of intersections.
Each block face should include a minimum of two
vehicular lights; one light at an intersection and one light
near mid block. Where obstructions at these locations exist,
a plan review should be coordinated with the City of
Lubbock.
Pedestrian lighting should be spaced every 60 feet on
center along each side of a block, centered between street
trees. The dimension of 60 feet is derived from the historic
block dimension of most Downtown blocks being 270 foot
square. One pedestrian light per every 60 feet should allow
for 5 pedestrian or vehicular lights per historic 270 feet of
each block face. Where vehicular lights are required, they
may be substituted for a pedestrian light. Where blocks
have been consolidated, this spacing should be maintained
as best possible to tie to the spacing throughout the
remaining Downtown area.
The following conditions will apply for residential
redevelopment projects encompassing one block face or more
with traditional single-family, townhouse, duplex, or similar
medium density residential housing.
Pedestrian light poles serving blocks with residential
structures should generally be spaced evenly in
relationship to the street trees. They should be spaced
every 125' on center along each side of a block. The
dimension of 125' is derived from the historic block
dimension of most Downtown blocks being 250' by
250'. One pedestrian light per every 125' should allow
for one pedestrian light per historic 250' of each block
face. Where vehicular lights are required, they may be
substituted for a pedestrian light. Where blocks have
been consolidated, this spacing should be maintained
where feasible to tie to the spacing throughout the
remaining area.
• Light poles will not obstruct a walkway into a residential
yard.
Vehicular lighting should be spaced at every intersection
with additional lights per every 270' of continuous block
length along each side of a block. Vehicular lighting at
intersections should include two lights per intersection on
diagonally opposing comers. Preferably, all intersection
lights will be on the southwest and northeast comers of
intersections.
