RE: Application of Downtown Neighborhood CouncillDave Stuart for funding from the
Historic District Public Improvement Program to install decorative fence/rail, brick
sidewalks, and retaining walls at 1105, 1145, 1389, and1470-1472 Locust Street
and 1323-1325 Bluff Street in the Jackson Park Historic District.
Dear Mayor and City Council Members:
INTRODUCTION
The Historic Preservation Commission has reviewed the application of Downtown
Neighborhood Council/Dave Stuart for funding from the Historic District Public
Improvement Program to install decorative fence/rail, brick sidewalks, and retaining
walls at 1105,1145,1389, and 1470-1472 Locust Street and 1323-1325 Bluff Street in
the Jackson Park Historic District. The application and staff report are attached for your
information.
DISCUSSION
Chairperson Dave Stuart excused himself from the table, indicating that he would
abstain from the vote because he is representing the Downtown Neighborhood Council.
Vice Chairperson Chris Olson presided.
Mr. Stuart presented the application to the Commission. He indicated the application is
for the installation of decorative fence/rail, brick sidewalks, limestone step, and retaining
walls at five locations in the Jackson Park Historic District.
He indicated that at 1105 Locust Street, the proposal is for continuation of the brick
paver sidewalk previously approved and funded under the HDPIP program. He
explained that at 1145 Locust Street, the proposal is for installation of the same brick
sidewalk pavers and a limestone step to match the new sidewalk grade. He said the
proposal for 1389 Locust Street is to install a brick sidewalk. He indicated that at 1470-
1472 Locust Street, a brick sidewalk was previously approved and funded under the

HDPIP program. He said the current HDPIP proposal for this property is to install a
retaining wall with a decorative fencelrail that would match a wall with a decorative
fence as shown in a historic photo submitted with the application. He reviewed the
proposal for 1323-1325 Bluff Street is to install a brick sidewalk and a retaining wall
similar to the one proposed at 1470-1472 Locust Street.
Mr. Stuart reviewed how the HDPIP funding for the sidewalks was calculated based on
the additional cost for brick sidewalk over standard concrete, and the HDPIP funding for
the limestone step and retaining walls with decorative fence/rail was based on the 3:1
split for the entire cost. He explained that the retaining walls would be constructed in the
public right-of-way, with a written waiver from the Engineering Department.
Staff Member Carstens reviewed the staff concerns with funding the limestone step and
retaining walls with decorative fencelrail under the HDPIP program, since these
improvements would be of private benefit but not public benefit. Staff Member
Wernimont explained the staff's suggested budget for the project, to fund just the brick
sidewalks. He added that the retaining walls with decorative fence/rail are eligible
expenses for the Historic Preservation Revolving Loan Fund, even if installed in the
public right-of-way so long as permission is obtained from the Engineering Department.
The Commission discussed the application. They discussed the grade changes
between the existing sidewalks and the new brick sidewalks. They debated the
inclusion of the retaining walls and fencing in the HDPIP program.
RECOMMENDATION
By a vote of 7 to 0 with one abstention by Chairperson Stuart, the Historic Preservation
Commission recommends that the City Council approve the project as submitted.
Bya vote of 6 to 0 with two abstentions by Chairperson Stuart and Commissioner
Olson, the Historic Preservation Commission recommends that the City Council
approve $24,346.95 in HDPIP funds for the installation of brick sidewalks at 1105
Locust Street, 1145 Locust Street, 1389 Locust Street, and 1323-1325 Bluff Street.
Sincerely,
C'vvu~ Q~~ /~

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)
may be modified to allow for more green space and landscaping components (refer to individual
site plans for modification details), The brick sidewalks will be installed by a contractor on the
current city's list ofapproved sidewalk contractors using a proposed "construction standard".
Abutting property owners are free to chose the color of brick as well as the pattern of the
sidewalk, Property owners have chosen to use either Robinson Brick's tumbled clay pavers in
the Santa Fe color, or Pine Hall brick "rumbled" pavers. A herringbone pattern matching
surviving examples of pavers and patterns historically used in sidewalks in Dubuque has also
been chosen by property owners, Two properties (four individual lots) (1323 & 1325 Bluff
Street, and 1470 & 1472 Locust Street) will also add a short retaining wall per historical
documentation of 1470 & 1472 Locust Street. Owners may perform some of the installation
work as in-kind contributions to reduce their out-of-pocket expenses. Projects are planned to be
start in the Spring and be complete by the end of the Summer of 2005
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 consistent 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 "construction 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 construction standard
titled "BRICK SIDEWALKS, DRIVEWAYS, HANDICAPPED RAMPS, STREETS AND
ALLEYS". That standard is based on current industry practices and will produce a sidewalk that
is not only historically appropriate but will last many decades without problems. This standard
has been used to recently install the new sidewalks and ADA ramp at 1105 Locust Street.

BRICK SIDEWALKS. DRIVEWAYS. HANDICAPPED RAMPS. STREETS AND
ALLEYS
Descriotion. 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 following:,
A. Brick oavers. Vitrified clay paver shall conform to the requirements of ASTM
C902, Class SX, Type I, Application px. The units shall be standard 4" x 8" size
having dimensions onv." x 4" x 8" (including spacer nibs on the side), chamfered
edges on both bed surfaces, 12,500 psi minimum compressive strength and below
6% cold water absorption. Dimensional tolerances around the mean values for
length, width and depth shall be:t 1/16 ofan inch. Clay pavers conforming to the
requirements of ASTM CI272, Type F, ApplicationPX with the units of the
standard 4" x 8" size having dimensions of2 3/4" x 4" x 8" (including spacer nibs on
the side), chamfered edges, 12,500 psi minimum compressive strength and below
5% cold water absorption shall also be acceptable. Color shall be as specified in the
contract.
B. Recvcled antiaue jlIlvers. Antique brick pavers closely matching existing pavers in
size and shape, color and texture, and free of obvious defects shall be acceptable
when used to repair existing brick streets, alleys and sidewalks.
C. Beddina 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 screenings 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 ofCSA A179. Alternately,
bedding sand may be used.
E. Base material. Aggregate base shall be of a "road bed" or "crusher-run" type
crushed gravel material with W' top size and shall conform to the requirements of
ASTM D 2940.
F. Edae 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 type
specifically designed to retain brick pavers.
Removal of Sidewalks. Drivewavs and Handicaooed Ramos. 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 (I") 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 of95% 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 under the base material and at the
base/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 lifts six inch lifts to at least 95% density. The finished surface of
the compacted base shall have a tolerance of +1- 3/8" over 10'. Any depressions shall be
filled with base material and compacted. At a minimum, the base material shall extend
beyond the pavement perimeter a distance equal to the depth ofthe 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 amount
as necessary to avoid cutting full bricks at edges. Ifnecessary, 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 'I." joint width shall not be used. Any individual bricks with upper surface chips,
depressions or other deformities which are more than 'I." 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 Reauirements:
Transverse slope. A sidewalk shall be set with a transverse slope of the finished walking
surface of ',4" per foot toward the curb unless otherwise directed by the Engineer.
Gradient offill. The space between a sidewalk and the curb shall be graded with a gradient
of approximately \1," 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 requirements 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 minimum width of a brick sidewalk on public property shall be 4'.
A "tree 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 ',4" along the entire with ofthe abutment.
ReDair of existing brick streets. alleys. sidewalks and ramDS. 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 requirements.
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 Engineer. 1flocated within 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 impracticalliterai 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.

Bluff Street
Property Owner: City of Dubuque
Applicant: Downtown Neighborhood Council/David Stuart
Project: To install decorative fence/rail, brick sidewalks and retaining wall
Historic Preservation District: Jackson Park Landmark: No
Style: None
Funding: Historic District Public Improvement Program
Date Built: N/A
Existing Zoning: OR Office Residential/ OC Office Commercial, C-4 Downtown
Commercial and R-4 High Density Multi-Family Residential
Present Land Use: Mixed commercial, office and residential uses
o Not Evaluated
Level of Rehabilitation:
o Design for Historic Features
o Alteration/Addition
Level of Sianificance:
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 Historic 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 1105/1145/1398 Locust Street and 1323/1325 Bluff Street. They are also
requesting funding for an installation of a limestone step at 1145 Locust Street, and
fence and retaining walls at 1323/1325 Bluff Street and 1470/1472 Locust Street 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.

Staff Comments: The Planning Staff and Engineering Staff have reviewed the
application. Staff questioned the use of the HDPIP funds to finance the installation of
the retaining walls, fences and limestone steps. Staff felt that this would be an
improvement that would primary benefit the property owner and not the public. Staff felt
that this may lead to a precedent for more property owners to request fences and
retaining walls to be built in the public right-of-way with HDPIP funds. Staff believes
these improvements provide a private benefit, and the public does not receive any
benefit from these retaining walls, fences and limestone steps. The public does fully
benefit from the brick paver sidewalks, and so staff recommends that the HDPIP funds
be used to cover the cost of the sidewalk improvements only. Staff noted that the
retaining walls, fences and limestone steps can be placed in the public right-of-way at
the owner's full expense after receiving written approval from the Engineering
Department to build in the public right-of-way. The following table shows the cost
breakdown for the request if the following costs are removed from the original request:
. $5,412 for retaining wall and fence and $100 for waiver to build in the public
right-of-way at 1323/1325 Bluff Street.
. $5,412 for retaining wall and fence and $100 for waiver to build in the public
right-of-way at 147011472 Locust Street.
. $800 for limestone step at 1145 Locust Street.
Total Proiect Cost $39,488.61
Total Grant Reauest $23.596.96
Total oro owner's share $15,891.65
Grant to total cost 59.76%
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
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 ware taken into consideration with the
Streetscape and Landscape Guidelines.
