SUBJECT: Downtown Neighborhood Council-
Historic District Public Improvement Program
I respectfully request that this item be tabled.
If, at public hearing, the Franchise Fee is not adopted, I would recommend that this
funding be denied so the available funds can be used to fund the FY 2004 cuts and fare
increases that had been proposed to solve the current budget shortfall.
Should the Franchise Fee be approved, I would ask that this item stay tabled until after
the Iowa Supreme Court decision on gaming taxes to see if:there is any money to fund

Downtown Neighborhood Council/Doug Stillings/David Stuart
Public Right-of-Way at 1105, 1470, 1472 and 1492 Locust Street
Request for funding to install brick paver sidewalks
Dear Mayor and City Council Members:
The City of Dubuque Historic Preservation Commission has reviewed the above-cited
request. The application, staff report and related materials are attached for your review.
Discussion
Dave Stuart, member of the Downtown Neighborhood Council spoke in favor of the
request. He indicated that the Downtown Neighborhood Council is proposing to install
brick paver sidewalks in the public right-of-way. He referred to the history of brick
sidewalks in the City of Dubuque and presented photos of existing brick sidewalks. He
noted that the Downtown Neighborhood Council endorses the brick sidewalks as a pilot
project. Mr. Stuart also discussed the width of the sidewalks throughout the districts. He
indicated that he would like to reduce the width of his sidewalk to meet the same width
as the adjacent sidewalk. He stated that since Central High School was demolished
that there is no need for a wide sidewalk. He noted it would provide a largei' green
space area in front of his property.
He discussed that several property owners would like to observe the maintenance of the
sidewalks prior to absorbing the addition cost. He stated that the property owner will be
responsible to pay for the cost of a standard Portland cement sidewalk and the funding
will only be used to pay for 75% of the extra cost. He noted they are requesting
$12,155.03 from the Historic District Public Improvement Program.
Planning Services Manager Laura Carstens presented the staff report noting that brick
sidewalks are consistent with the adopted City of Dubuque Streetscape and Landscape
Guidelines. She noted that brick sidewalk standards will need to be established and the
Engineering Department will need approve the sidewalks.

A. Project Summary. Discuss the project and the key project work elements of the
proposed streetscape improvements.
Project will replace existing gray portland cement sidewalks with new brick (vitrified clay)
meeting current industry standards for pavers. Individual abutting property owners electing to
replace their sidewalks are responsible for all matching funds requirements. With the sidewalk
replacement, the width of the '~planting lawn" (the grass area between the curb and the sidewalk)
will be modified to allow for more green space and landscaping components. The brick
sidewalks will be installed by a con~ractor on the current city's list of approved sidewalk
contractors using a proposed %onstmction standard". Abutting property owners are free to
chose the color of brick as well as the pattern of the sidewalk. All have chosen to use Robinson
Brick's tumbled clay pavers in the Santa Fe color with a herringbone pauern as that most closely
matches surviving examples of pavers and patterns historically used in sidewalks in Dubuque.
Owners may perform some of the installation work as in-kind conlributions to reduce their out-
of-pocket expenses.
B, Neighborhood Impact and support. Describe the current conditions and how the project
will improve the neighborhood and/or project area, Discuss the level of neighborhood and
property owner support.
Dubuque's Streetscape and Landscape Guidelines for the Jackson Park Historic District
recommend "materials for new sidewalks and crosswalks that are cons~stem with the historic
materials, such as brick pavers... ", and further states that "It is currently City policy to remove
and replace these [historic sidewalk materials such as brick) materials during new construction,
either with broom finish poured concrete or, more recently, stained concrete pavers or stained
and stamped concrete. Preservation and replication of any of the historic masonry materials for
sidewalks would be appropriate in the Jackson Park District and adjacent neighborhoods, and is
the recommended treatment."
Currently the City has no "constmution standard" for brick paver sidewalks. The City does
have a standard for Portland Cement Concrete sidewalks and requires, per its Sidewalk
Inspection Policy, that defective sidewalks be replaced per that standard. That effectively
precludes a property owner from installing a historically appropriate brick sidewalk in public
right of way.
Members of the Downtown Neighborhood Council have produced a draft consu-uction
standard rifled "BRICK SIDEWALKS, DRIVEWAYS, HANDICAPPED RAMPS, STREETS
AND ALLEYS". That standard is based on current industry practices and should produce a
sidewalk that is not only historically appropriate but will last many decades without problems.
A few individual property owners in the neighborhood have committed to becoming the first
to add the sidewalks with many others interested and wisking to observe the installation and
maintenance (snow shoveling) before committing to the expensive proposition of sidewalk
replacement.

Jackson Park
SIDEWALKS, WALKWAYS, AND CURBS
Sidewalks throughout the Cathedral District were
either wood plank in their earliest form, which was
later replaced with brick pavers m different
patterns, or poured concrete with a crushed
limestone aggregate. It ~s currently City policy to
remove and replace these materials during new
construction, either with broom finish poured
concrete or, more recently, stained concrete
pavers or stained and stamped concrete.
Preservation and replication of any of the historic
masonry materials for sidewalks would be
appropriate i~ the Jackson Park District and
adjacent neighborhoods, and is the recommended
treatment. Substitute materials can be considered
for issues of cost and code compliance, however.
Limestone was the traditional curb material
throughout the city. As with the sidewalks, it has
been City policy to remove and replace these
curbs with poured concrete curbs and gutters as
they deteriorate, or when they interfere with street
or 'utility repairs. Limestone is recommended for
use as a straight curb material in these areas due
to its historic presence, but alternate materials may
be considered for ease of maintenance, reduced
cost and increased durability.
RECOMMENDED
JP-9
· Identification and preservation of original historic paving and limestone curbing
materials where they survive, particularly in areas where the curbing has a
substantial visual impact on the view from the street.
· Materials for new sidewalks and crosswalks that are consistent with the historic
materials, such as brick pavers and crushed-limestone aggregate concrete.
· Replacement of deteriorated limestone curbs with new limestone.
· New sidewalks that restore the historic width of the walkways, where
contemporary usages and City codes allow.
ACCEPTABLE
· Substitute materials that simulate the original paving, such as colored concrete
pavers and stamped and/or stained concrete.*
· Substitute materials that simulate the original limestone curbing in color,
texture, and shape, such as straight curbs of tinted concrete poured with a
textured form liner.*
· As a last resort, new or common materials, such as standard concrete, when it
is not economically viable to save and repair originals or to use substitute
materials which simulate the original in appearance.*
NOT RECOMMENDED
.Removal of historic curbs and gutters without an appropriate replacement.
· Use of pebble-surface concrete sidewalks.
· Use of asphalt for a paving material on sidewalks.

BRICK SIDEWALKS, DRIVEWAYS, HANDICAPPD RAMPS, STREETS AND
ALLEYS
Description. This work shall consist of removal, and disposal of existing Portland Cement
Concrete sidewalks, driveways and handicapped ramps and construction and/or repair of
brick sidewalks, driveways, handicapped ramps, streets and alleys according to the plans and
these specifications.
Materials.. Materials used shall conform to the following2.'
A. Brick pavers. Vitrified clay paver shall conform to the requirements of ASTM
C902, Class SX, Type 1, Application PX. The units shall be standard 4" x 8" size
having dimensions of 2¼" x 4" x 8" (including spacer nibs on the side), chamfered
edges on both bed surfaces, 12,500 psi m/n/mum compressive strength and below
6% cold water absorption. Dimensional tolerances around the mean values for
length, width and depth shall be + 1/16 of an inch. Clay pavers conforming to the
reqmremems of ASTM C1272, Type F, Application PX with the units of the
standard 4" x 8" size having dimensions of 2 3/4" x 4" x 8" (including spacer nibs on
the side), chamfered edges, 12,500 psi mimmum compressive strength and below
5% cold water absorption shall also be acceptable. Color shall be as specified in the
contract.
B. Recycled antique pavers. Antique brick pavers closely matching existing pavers in
s/ze and shape, color and texture, and free of obvious defects shall be acceptable
when used to reparr existing brick streets, alleys and sidewalks.
C. Bedding sand. Bedding sand, typically mason's or concrete sand, shall conform to
the grading requirements of ASTM C33 or CSA A23.1 with no greater than 1%
passing the 0.075mm [No. 200) sieve. (Stone dust or waste screen/ngs should not be
used as they have an excessive amount of material passing the 0.075 mm sieve.
D. Joint sand. Joint sand shall conform to the requirements of CSA A179. Alternately,
bedding sand may be used.
E. Base material. Aggregate base shall be ora "road bed" or "crusher-mn" type
crushed gravel material with ~" top s/ze and shall conform to the reqmrements of
ASTM D 2940.
F. Edge Restraints. Edge restraints may be of brick-stood-on-edge, pre-made plastic or
metal, or troweled concrete with backfill. Pre-made plastic shall be of the Cpc
specifically designed to retain brick pavers.
Removal of Sidewalks, Driveways and Handicapped Ramps. The Contractor shall remove
the sidewalks, driveways and handicapped ramps as shown in the contract document or
designated by the Engineer. If only portions of sidewalks, driveways and handicapped
ramps are to be removed, the boundaries of removal shall be made by a vertical cut not less
than one inch (1") deep before breaking. Any areas of sidewalks, driveways and
handicapped ramps not designated for removal but which are damaged by the Contractor's
operations shall be removed and replaced by the Contractor without compensation.
Construction. Construction of brick paver sidewalks, driveways and handicapped ramps
shall meet the following requirements:
Preparation of Subgrade. The subgrade upon which the brick paver sidewalks, driveways
and handicapped ramps is to be placed shall be prepared by excavating or filling with
suitable earth to such depth below the gradeline that when tamped or rolled smooth, firm
and hard, the subgrade will be uniform and at the required depth below the finished
gradeline. Soil shall be compacted to a minimum of 95% density. All soft areas shall be
removed and filled with suitable material which shall be thoroughly compacted in layers not
exceeding six inches (6") in thickness.
Geotextile Fabric. Geotextile fabric shall be placed trader the base material and at the
hase/sand bedding interface if specified in the contract Fabric shall be turned up against
vertical surfaces to contain and prevent the migration of the base or bedding sand material.
Preparation of Base. Base material shall be a minimum thickness of six inches (6") for
sidewalks, and handicapped ramps and eight inches (8") for driveway areas. Base shall be
compacted in maximum hfis six inch lifts to at least 95% density. The finished surface of
the compacted base shall have a tolerance of+/- 3/8" over 10'. Any depressions shall be
filled with base material and compacted. At a miuimum, the base mater/al shall extend
beyond the pavement perimeter a distance equal to the depth of the base material.
Sand bedding. Sand bedding shall be screeded to a consistent even thickness between one
and 1-1/2 inches using the edge restraint or other suitable temporary forms. Any voids
resulting from removal of temporary forms shall be filled with sand. Bedding shall not be
compacted or further disturbed before placing bricks.
Edge restraints. Edging may be added before or after laying the bricks depending on the
brick pattern and type of edge restraint specified in the contract document Brick-stood-on-
edge type restraint shall be backfilled with base material after laying brick surface. Pre-
made plastic edge restraint shall be restrained by 8" spikes hammered through pre-formed
holes into the stone base.
Laying the brick. Brick pavers shall be placed on the uncompacted bedding sand in the
pattern specified in the contract. The edge restraint system may be adjusted a small amoum
as necessary to avoid cutting full bricks at edges. If necessary, pavers shall be cut using a
power saw with masonry blade. Bricks shall be spaced with a joint width of 1/16" to 3/16".
Any individual bricks demonstrating a size variance which does not allow its placement with
less than a ¼" joint width shall not be used. Any individual bricks with upper surface chips,
depressions or other deformities which are more than V4" deep and constitute more than 10%
of the bricks surface shall not be used.
Compaction. After the pavers are placed in the specified pattern they shall be compacted
into the bedding sand with a plate compactor. After the initial compaction, bedding sand or
joint sand shall be swept and vibrated into the joints between the bricks until full.
Backfill. After the brick pavers have been placed and compacted, the spaces along the edges
of the sidewalk shall be backfilled to the required elevation with approved material. The
material shall then be loosely compacted as appropriate and the surface neatly graded.
Disposal of Surplus Material. Surplus or waste material resulting from the construction
operations shall be disposed of by the Contractor.
General Requirements:
Transverse slope. A sidewalk shall be set with a transverse slope of the finished walking
surface of ¼" per foot toward the curb unless otherwise directed by the Engineer.
Gradient of fill. The space between a sidewalk and the curb shall be graded with a gradient
of approximately ½" per foot toward the curb if site conditions allow.
Handicapped Ramps. Design for handicapped ramps constructed of brick and located on
public property shall conform to the surface dimension mqnimments of concrete ramps
Any ramp design shall be coordinated with the City Engineering Department to ensure
conformance with Americans with Disabilities Act requirements.
Width of Sidewalks. The minimam width ora brick sidewalk on public property shall be 4'.
A '~ee relief" may encroach up to one foot into that minimum width. In the event that the
site renders a 4' with impractical, City Engineering Department approval shall be obtained.
Brick sidewalks may be constructed wider, the same width, or narrower than the sidewalk
they replace.
Horizontal alignment with abutting sidewalks. The side edges of brick sidewalks shall not
be required to align laterally with other walks they abut. However, both of the side edges of
the narrower sidewalk must fall at or within the side edges of the wider sidewalk.
Vertical alignment with abutting sidewalks. The newly completed brick sidewalk shall align
with the abutting sidewalk vertically within ¼" along the entire with of the abutment.
Repair ofexistin~ brick streets, alleys, sidewalks and ramps. Existing streets, alleys,
sidewalks and ramps shall be repaired using recycled antique or new brick that closely
matches existing paving material. New brick shall conform the brick paver reqmrements.
To the greatest extent practical, the repair shall conform to these construction standards.
Damaged areas may be repaired without resetting the entire surface as specified in the
Contract.
Provisions for snow melt. Hydronic tubing shall be installed either within the base material
or the sand bed as specified by the En~neer. If located with/n the sand bed, the sand bed
thickness may be increased to accommodate the tubing as specified by the Engineer.
Deviations: Deviations from these standards are acceptable where site conditions preclude
or render impractical hteral compliance. Any deviations must be documented in writing and
approved by the Engineer. City Engineering Department approval shall be obtained for any
deviations on public property.

Physical Characteristics: The right-of-way located in the Jackson Park Historic District
borders many historic buildings. The buildings located throughout the Jackson Park
Historic District are primarily mixed use residential, commercial and office. The bulk of
the Jackson Park Histodc District is primarily residential. The right-of-way and
sidewalks in the Jackson Park Historic District are both narrower than those found in the
nearby commercial area downtown.
Staff Analysis: The applicants are applying for funding from the Historic District Public
Improvement Program for proposed streetscape improvements in the public right-of-
way. The Downtown Neighborhood Council has proposed the installation of brick paver
sidewalks at various locations throughout the district. As stated in the Historic District
Public improvement Program application form individual property owners are not
eligible to apply for funding. The Downtown Neighborhood Council endorses the project
and indicates that these sidewalks would be a test case. In the application, it states that
several property owners would like to see how the sidewalks are installed and
maintained (snow shoveling) before committing to the expensive proposition of sidewalk
replacement.
The role of the Historic Preservation Commission in reviewing this project is to serve as
an advisory design review body to the City Council for review of public works projects
which have historic preservation implications in historic districts. The Commission is
also responsible for providing a recommendation to the City Council about funding
projects from the Historic District Public Improvement Program. The Commission's
Design Review Staff Report - Downtown Neiglqborhood Council

recommendation will go on to the City Council with the application materials for their
review and approval of the project.
Compliance with Design Guidelines: In 2002, the Streetscape and Landscape
Guidelines were created to help provide recommendations for public improvements in
the public right-of-way. Brick paver sidewalks were taken into consideration with the
Streetscape and Landscape Guidelines.
