RESOLUTION
WHEREAS, on December 3, 2001, the City Council of the City of Lubbock (the "City
Council") authorized and established the Central Business District Tax Increment
Financing Reinvestment Zone Board (the "TIF Board") for, among other things, to generate
funds for Downtown Lubbock public improvements that benefit the City of Lubbock (the
"City"), its residents, and property owners; and
WHEREAS, the TIF Board and its Master Developer for Downtown Redevelopment (the
"Developer") have worked with the Lubbock Economic Development Alliance ("LEDA")
and Market Lubbock, Inc. ("MLI") to create a set of design standards for the public right-
of-way that will help to improve the fagade, roadway, and walkway aesthetic in downtown;
and
WHEREAS, the TIF Board, the Developer, LEDA, MLI, and various downtown business
and property owners believe that the existing set of design standards requires an update to
prevent the requirements in the design standards from inadvertently discouraging
development in downtown Lubbock; and
WHEREAS, at its meeting on December 13, 2017, the TIF Board unanimously approved
amendments to the Downtown Public Improvements Design Standards that more clearly
identify what parts of downtown Lubbock are subject to the design standards, what types of
development projects are subject to the design standards, and what process ought to be
taken when the design standards are applied to a project; and
WHEREAS, the TIF Board recommends that the City Council adopt the amended design
standards in order to promote local economic development and to stimulate business and
commercial activity in the City; and NOW THEREFORE:
BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF LUBBOCK:

Downtown Public Improvements Design Standards 2
CHAPTER 1: Introduction
Overview
In 2008 the City Council of the City of Lubbock (Council) adopted
the City of Lubbock Downtown Revitalization Action Plan (CBD
Action Plan) to articulate the preferred vision for the revitalization
process of the Central Business District (CBD) of the City of Lubbock
(see Figure 2). 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 (City). The City's Planning Department adjusted the
boundaries of the CBD Action Plan areas slightly to coordinate with
existing and proposed zoning in the CBD.
While the CBD Action Plan provides a vision for the CBD, more
specific technical guidance is needed for a coherent, unified design in
the CBD. This document is just one of several documents needed to
guide that design.
The primary mechanism for private sector redevelopment is the CBD
zoning districts in the City of Lubbock Code of Ordinances (Code).
The Council, on the recommendation of the Planning and Zoning
Commission (P&Z), adopted the CBD zoning districts into the Code
that provide for the specific needs of different areas of the CBD,
including those identified in the CBD Action Plan.
Like other sections of the Code, each CBD zoning district includes
standards for: height and building orientation; building mass and
scale; parking areas; and, landscape areas. Each of the CBD zoning
districts fully adopts the Design Standards for the Central Business
District (CBD Design Standards) in order to provide more detailed
design standards for new construction and rehabilitation projects in
the CBD. The CBD Design Standards provide a mechanism for
review and approval of construction and remodeling plans within the
CBD zoning districts, including an appeals process.
This document, the Downtown Public Improvements Design
Standards (Public Improvements Standards), serves as the second
guide for CBD development. While the CBD zoning districts, and the
CBD Design Standards that are incorporated within them, govern
private property within the CBD, they also include requirements for
parts of the public right-of-way. These Public Improvements
Standards do not replicate the requirements of the CBD zoning
districts, but set a minimum standard for all right-of-way
improvements in the CBD.
These Public Improvements Standards provide a basic design concept
for right-of-way improvements in the CBD that can be used by the
City and by private developers. The public improvements suggested
in these Public Improvements Standards will create a desirable
environment for downtown life while providing a framework for
private development in the CBD. These Public Improvements
Standards will apply within the boundaries shown on Figure 1:
Public Improvements Standards Boundary.
Rebuilding the right-of-way improvements in the CBD will generally
follow the pattern of private development. These Public
Improvements Standards apply to all projects within the CBD,
whether privately funded by developers of adjacent property, or
publicly funded by the City or any other governmental entity.
Downtown Public Improvements Design Standards 3
Using the Downtown Public Improvements Design
Standards
These Public Improvements Standards apply to any project in the CBD that:
1. Affects the facade* of the structure on or in which the
project is planned;
2. Requires a building permit; and
3. Is valued at one hundred thousand dollars ($100,000) or
more.
The developer of any such project is required to have a building permit pre -
application meeting with the City of Lubbock Director of Planning, or his
designee, prior to the issuance of a building permit for the project. 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 and these Public Improvements Standards. If the
Director of Planning determines that the project satisfies the requirements of
the CBD Action Plan and these Public Improvements Standards, then the
project can proceed through the City's normal building permit process. The
Director of Planning, in consultation with respective members of City Staff,
may require that the developer of a project produce documentation that
provides evidence as to the value of the project. If a proposed project is in
the public right-of-way, or if a proposed project directly affects the public
right-of-way, then these Public Improvements Standards shall apply to the
project even if the project would have otherwise been exempt from these
Public Improvements Standards. If a proposed project is the result of an act
of God, a natural disaster, or an event beyond the control of all parties related
to the proposed project, then these Public Improvements Standards shall not
apply.
If the Director of Planning determines that the project does not satisfy the
requirements of the CBD Action Plan and these Public Improvements
Standards, then the developer of the project has two (2) options:
1. The developer can bring the project into conformance with the
CBD Action Plan and these Public Improvements Standards; or,
2. The developer can work with City Planning staff to request that
the Urban Design and Historic Preservation Committee (UDHPC)
waive certain requirements in the CBD Action Plan and these
Public Improvements Standards for the project. The UDHPC may
approve the application as submitted, approve the application with
conditions, or deny the application. When conditions are attached
to a project's approval, the conditions will require modifications
to the proposed design that are necessary to ensure the project's
conditional compliance with these Public Improvements
Standards.
The developer of the project may bring to the Zoning Board of Adjustment
(ZBA) of the City an appeal of the decision of the UDHPC concerning the
project.
*For the purposes of these Public Improvements Standards, a faVade includes the walkway,
parking area, landscape, building edge, building signage, and the exterior of any building
within the CBD. Exterior painting or changes to the interior of a building that do not affect
the exterior of the building are not subject to these Public Improvements Standards. Public
projects that undergo a public review or comment process do not require a review by the
UDHPC, but still require standard permitting and staff review.

Downtown Public Improvements Design Standards 5
CHAPTER 2: Design Concepts
The CBD is distinguished from other parts of Lubbock by the presence
of numerous historic buildings sites, the use of time-honored building
materials, and the large scale of buildings at the street level. As the
CBD returns to a center for living, working, and recreation, a
consistent urban character will need to be maintained in the CBD
through the use of historical elements and appropriate building scale.
Although each of the CBD zoning districts has unique needs and
opportunities for redevelopment, the right-of-way elements provided
in these Public Improvements Standards will be coordinated
throughout the CBD. Street furnishings are a fundamental component
to the success of street and neighborhood aesthetic cohesiveness.
Street furnishings provide places places for people to sit, deposit trash,
and secure bicycles. Beyond the functional benefits, the right street
furnishings can attract and engage the public by creating a safe,
comfortable, and welcoming environment.
Historic Brick Pavers
Many of the streets in the CBD are paved with fired clay brick pavers.
These bricked streets were built during the 1920's and 1930's
primarily by the City's public works programs. Over the years, much
of the historic brick removed from CBD streets during reconstruction
projects has been stored for future repair, construction, and reuse. If a
project in the CBD requires the use of brick pavers, a developer should
use such stored historic brick before using new or non -historic brick
pavers. Before a property owner or developer completes the design of
or begins construction on a CBD project, the property owner or
developer should contact the City to verify the available quantity and
size of historic brick pavers that are required for the project.
In 2006, the Council adopted revisions to the Code that protected most
of the existing brick pavers in the CBD. The Code was amended to,
among other things:
• 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; and
• Specify a review process for removal that allows an UDHPC
determination with appeal to the 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 Code 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 the CBD, 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 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 fifty percent
(50%) of the sidewalk surface area. See Figure 7: Corridor and
Gateway Parkway
The clear pedestrian path of the sidewalks should be at least five
feet (5') wide when the total parkway width is less than ten feet
(10') wide, with the remaining width serving as the amenity zone.
If the total parkway width is ten feet (10') wide or greater, the
sidewalk should be fifty percent (50%) 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.
HERRINGDONE (2)
PARQUET (5)
Downtown Public Improvements Design Standards 8
RUNNER BOND (7)
*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 (4) sides shall be updated at
once.
Exposed aggregate concrete is not an approved paving surface for
redevelopment in the CBD.

Specialty Vehicular and Pedestrian Lighting
Lighting is important both for the safety and ambiance of a
neighborhood. Pedestrian level lighting further reinforces the human
scale of the CBD and encourages outdoor activity.
In the CBD, specialty lighting fixtures have been selected to provide
a unique identity for the area. Two (2) 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 restricted to gateway and
corridor streets as identified in Chapter 3. Gateway and Corridor
Streets.
• Street and pedestrian lighting is specified 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.
• A lighting plan will be submitted to and approved by the City on
all projects where lighting is required or proposed in the right-of-
way.
Pedestrian lighting shall be tied to streetlights 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 Public Improvements 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 the CBD, 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 the CBD 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 the
CBD.
Any proposed artwork or banner in the public right-of-way should be
submitted to the City for consideration and approval before the work
is installed. Artwork and banners will meet all Code requirements and
be approved by the City's Planning Department. Any such artwork or
banner may neither have a business name included nor be an artistic
expression of the particular type of business on the parcel.
Street Sign age
Street signs, stop signs, parking signs, directional signs, and
informational signs will be coordinated to establish a unified
appearance within the CBD.
• Signage should be placed to ensure a clear pedestrian pathway
without restricting visibility at intersections
• The City shall provide a decorative logo on street sign toppers as
recommended by the CBD Tax Increment Financing 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
Resolution 2011-R0287, adopted by the City 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, the "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 conference with the Director of Planning will
include discussion on the requirements for underground utility
placement and positioning and the relocation of aboveground
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 corners 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
Benches in the CBD shall be Witt Oakley Standard Collection, Item
M6-BCH-ARM-BK, 72 inch slatted metal bench with armrest,
powder coated flat black, or equal as approved by Director of
Planning.

CHAPTER 3: Gateway and
Corridor Sheets
Introduction
During the initial studies of the CBD, 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, 10 Street,
Broadway Avenue, Buddy Holly Avenue, Mac Davis Lane, Glenna
Goodacre Boulevard, and Avenue L shown on Figure 5: Gateways
and Corridors. Avenue J, 15t' Street, and 16t' Street are corridor
streets connecting different areas of the CBD. Since 191h Street and
Avenue Q are under the jurisdiction of the Texas Department of
Transportation (TxDOT), any improvements on those streets must be
approved by and coordinated with TxDOT's District Office in
Lubbock.
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 the CBD as well
as transition between CBD zoning districts. Such features give the first
impression of a place. The CBD has several identified gateway points
that will require a special treatment. Recommended locations of
gateway features are indicated on Figure 5: 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 with results from traffic
studies. The traffic studies should show analysis with current street
layouts or proposed street modifications. Current and future impacts
to the CBD's pedestrian, vehicular, and transit circulation should be
considered in the traffic analysis.

Gateway Streets
Gateway streets are the major streets into the CBD and the
introduction of the CBD to most travelers. See Figure 5: Gateway 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 the City for staff for approval.
Broadway Avenue
Broadway Avenue has historically been the spine of the CBD, linking
the entrance to Texas Tech University and the CBD. In 1995,
improvements on Broadway Avenue between University Avenue and
Martin Luther King Boulevard were completed with a major TxDOT
grant. Pedestrian and vehicular lighting, street trees, and specialty
paving were early efforts to establish an urban design theme for the
CBD.
Some changes will be needed to unify Broadway Avenue's existing
enhancements with those proposed for the rest of the corridor. 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 CBD,
terminating at IH-27 on both the north and south. The Buddy Holly
Avenue right-of-way measures one hundred feet (100') 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

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.

Corridor Streets
Corridor streets serve as the crucial links between districts within the
CBD. 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 15`h Street and Wh 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 seventy-five feet (75') 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 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.
1 Sth Street & 16th Streets
15th Street and 161h Street between Avenue J and Crickets Avenue are
also corridor streets with the Depot District and will receive a similar
treatment to Avenue J.

CHAPTER 4: Landscaping
General Landscaping
The following general landscaping standards apply to all public right-
of-way in the CBD and should be used as a supplement to the existing
requirements for right-of-way maintenance in the Code. 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 that promote water conservation.
When a private developer initiates a project in the CBD, 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 Code, shall not be allowed within
the area included in these Public Improvements Standards.
• A balance of trees, shrubs, ornamental grasses, and
groundcover is encouraged. Climate -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 CBD.
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 one and one-
half inches (1.5") 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
three inches (Y) 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
• Trees in or adjacent to the right-of-way will be trimmed so that
foliage is less than eighty inches (80") above the top of curb
of the adjacent street. Plant materials other than trees in the
right-of-way may not exceed two to three feet (2'-3') in height
as required by the Code, Section 40.03.212.
• Turf will only be used in low -density residential parkways,
single-family yards, public parks, and open spaces exceeding
four hundred square feet (400 sgft) in the CB-3 Zoning
District.

Street Tree Framework
Street trees are inviting and help define major gateways and corridors
in the CBD. 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 CBD, Figure 9: Street Tree Framework Plan, specifies the specific
tree species for each street and at each intersection. Trees will have a
minimum four -inch (4") 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 sixty
feet (60') on center along a street block with allowance for
variations in spacing for curb cuts, alleys, and drives.
The sixty -foot (60') spacing is derived from the historic block
dimension of most CBD blocks being approximately two
hundred fifty feet (250') square with twenty -foot (20') alleys
in the center for a total block dimension of two hundred
seventy feet (270'). One (1) tree per every sixty feet (60)
should allow for an approximately forty-five feet (45') of clear
zone from the property line corners of each block and five (5)
subsequent trees in the midblock zone per historic two hundred
seventy feet (270') 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 along 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 CBD. 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 CB-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: Street 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 (2) 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 CBD 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 (1) per mid
block or one (1) per every one hundred twenty-five feet
(125') of continuous block length along each block face.
Vehicular lighting at intersections should include two (2)
lights per intersection on diagonally opposing corners.
Preferably, all intersection lights will be on the southwest
and northeast corners of intersections. Each block face
should include a minimum of two (2) vehicular lights; one
(1) light at an intersection and one (1) light near mid block.
Where obstructions at these locations exist, a plan review
should be coordinated with the City.
Pedestrian lighting should be spaced every sixty feet (60')
on center along each side of a block, centered between street
trees. The dimension of sixty feet (60') is derived from the
historic block dimension of most CBD blocks being two
hundred seventy feet (270') square. One (1) pedestrian light
per every sixty feet (60') should allow for five (5) pedestrian
or vehicular lights per the historic two hundred seventy feet
(270') 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 CBD.
The following conditions will apply for residential
redevelopment projects encompassing one (1) 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 one hundred
twenty five feet (125') on center along each side of a block.
The dimension of one hundred twenty five feet (125') is
derived from the historic block dimension of most
Downtown blocks being two hundred fifty feet (250')
square. One (1) pedestrian light per every one hundred
twenty five feet (125') should allow for one (1) pedestrian
light per historic two hundred fifty feet (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 two hundred seventy feet
(270') of continuous block length along each side of a block.
Vehicular lighting at intersections should include two (2)
lights per intersection on diagonally opposing corners.
Preferably, all intersection lights will be on the southwest
and northeast corners of intersections.
