Van Milligen MCVM/jh Attachment cc: Barry Lindahl, Corporation Counsel Cindy Steinhauser, Assistant City Manager Laura Carstens, Planning Services Manager D~ ~ck~ MEMORANDUM November 8, 2004 TO: Michael Van Milligen, City Manager FROM: Laura Carstens, Planning Services Manager SUBJECT: Proposed Standards for Downtown Sidewalk Patterns Introduction Engineering and Planning Services staff has been working with the City Manager's Office and the Leisure Services Department on proposed standards for Downtown sidewalk patterns. The intent is to establish a pattern that will guide future public and private sidewalk improvement projects in the Downtown, and respond to inquiries from Downtown owners and developers. City staff presented an initial recommendation at the June 21, 2004 City Council meeting. At that meeting, City Council members directed staff to: . Provide additional information about the proposed standards. . Evaluate conformance with the Downtown Master Plan. . Solicit input from property owners, key stakeholders and Dubuque Main Street Ltd. . Solicit input from the Historic Preservation Commission (HPC). City staff has complied with the City Council's directive. The enclosed information is provided for discussion at the City Council work session on November 15 at 5:30 p.m. How did development of these standards begin? Engineering and Planning Services staff initiated development of these standards in response to inquiries from Downtown property and business owners and developers who are planning sidewalk repairs and replacements, about what type of sidewalk color and pattern is appropriate for the public sidewalks along their properties. A number of these inquiries have been for properties in the Old Main Historic District. To date, City staff has relied on the City's Streetscape and Landscape Guidelines for Historic Districts and on previously-approved sidewalk improvements for guidance. Sidewalk Paving Pattern Page 2 Some sidewalks in the Downtown have been replaced. Many sidewalks, especially on side streets, are the standard grey concrete. Without a cohesive, uniform paving pattern for the Downtown sidewalks, however, a variety of patterns and colors exists. As a result, staff is not able to provide clear direction to owners and developers. How do the proposed standards comply with the Downtown Master Plan? The City Council recognized the importance of the historic, architectural and cultural resources of downtown and surrounding neighborhoods with the adoption of the Downtown Dubuque Master Plan in 2004. The Downtown Master Plan lists the following priority actions related to the Downtown sidewalk paving patterns: . Complete the implementation of the Downtown streetscape improvements along the remainder of Main Street from 1st to 14th Streets. The streetscape connection will reinforce the linkages between downtown residential and commercial uses. As a starting point, the streetscape I landscape guidelines developed for the historic districts can serve as a model. . Strengthen the connectivity between the Port of Dubuque and the CBD including the Cable Car Square shopping area. What is the project area? The project area for the Downtown sidewalk patterns generally is bounded by Bluff Street to Main Street and 14th Street to the Locust Street Connector, with an extension along 5th Street to the Port of Dubuque entry. What are the proposed standards for Downtown sidewalk patterns? Sheet #1 shows the proposed Downtown Sidewalk Pattern. The pattern has a broom finish, saw cuts and small charcoal pavers. It uses "bump-outs" with a stamped herringbone pattern to define "No Parking Zones" and provide spaces for street trees where right-of-way is wide enough. The proposed standards for the Downtown Sidewalk Pattern vary in color and layout depending on location as follows. Main Street Pattern Sheet #2 shows the Main Street Pattern. This pattern presently is found on Main Street from 9th Street to 5th Street through the former Town Clock Plaza pedestrian mall. Here the pattern is a wide (11 ') buff-colored concrete sidewalk with 8' traffic-calming "bump- outs" of quarry red concrete stamped in a herringbone pattern. In the Old Main Historic District and the Upper Main District, there will be fewer restrictions of on-street parking because the right-of-way is narrower. The sidewalk pattern in these districts will have fewer "bump-outs" of quarry red concrete. Sidewalk Paving Pattern Page 3 In accordance with the Downtown Master Plan, the Main Street Pattern is proposed for continuation along Main Street both north and south of the Town Clock area as follows: . Old Main District from the Locust Street Connector to 5th Street Upper Main District from 9th to 14th Streets Side Street Pattern Sheet #3 shows the Side Street Pattern. This pattern is a narrow (6') standard grey- colored concrete sidewalk with a 5' parkway of brick red concrete stamped in a herringbone pattern. The grey-colored concrete sidewalk uses a crushed-limestone aggregate concrete. The brick red portion uses a finish with shake-on hardener to match the Flat Iron Park sidewalk. In accordance with the Downtown Master Plan, the Side Street Pattern is proposed for the following streets: . 3rd Street from Main to Bluff Streets . 4th Street from Iowa to Bluff Streets . 5th Street from White to Bluff Streets . 8th Street from Locust to Bluff Streets . 9th Street from Iowa to Bluff Streets . Locust Street from 4th to 5th Streets Washinqton Park and Librarv Sidewalk Pattern Sheet #4 shows the Washington Park and Library Sidewalk Pattern, which is very similar to Flat Iron Park This pattern is a narrow (6') buff-colored concrete sidewalk with a 5' parkway of brick red stamped concrete with a herringbone pattern. The brick red portion uses a finish with shake-on hardener. This pattern will be used at: . Carnegie-Stout Public Library -- Locust Street and 11 th Street frontages . Washington Park -- all street frontages ADA Compliant Accessible Ramps Sheet #5 shows ADA compliant accessible curb ramps at street intersections with the recommended sidewalk paving patterns. The textured surface will be quarry red. How do the proposed standards comply with the Streets cape Design Guidelines? Sidewalks are addressed in the Streetscape and Landscape Guidelines for the Historic Districts of the City of Dubuque, Iowa as follows: . Recommended improvements include: preservation of original historic paving and limestone curbing, and materials for new sidewalks and crosswalks that are consistent with the historic materials such as brick pavers and crushed-limestone aggregate concrete. Sidewalk Paving Pattern Page 4 . Acceptable improvements include: substitute materials that simulate original paving, such as colored concrete pavers and/or stamped concrete. What input was received from property owners, key stakeholders and Dubuque Main Street Ltd.? City staff attended a meeting of the Dubuque Main Street Ltd. (DMSL) Board of Directors and staff on July 28, 2004 to present the proposed standards and take input. Board members were supportive and agreed with the City's approach to conduct an open house to obtain stakeholder input. There was also general consensus that this recommendation was consistent with the recommendations from the Downtown Master Plan. With the cooperation and assistance of DMSL, City staff sought input from Downtown business and property owners on the proposed standards for Downtown sidewalk patterns. Invitations were mailed for an Open House with City and DMSL staff on August 18, 2004 at the NICC Downtown Center. Session #1 ran from 11 :30 a.m. - 1 :00 p.m. and Session #2 ran from 4:00 p.m. - 5:45 p.m. Enclosed are the list of attendees and comments received. Generally, these stakeholders were supportive of the proposal and of the City limiting the property owners' cost share as much as possible. Interest in expanding the proposed standards to the Bluff Street I Cathedral area was expressed. What input was received from the Historic Preservation Commission? The proposed standards for Downtown sidewalk patterns will pass through the Old Main, Jackson Park, and Cathedral Historic Districts. One of the Historic Preservation Commission's duties is to conduct an advisory design review of these proposed public improvements based on the City's Streetscape and Landscape Guidelines for Historic Districts, and then provide a recommendation to the City Council. City staff reviewed the proposed standards with the Historic Preservation Commission at their June and August meetings. The Commission found the proposed Downtown Sidewalk Standards are consistent with the City's Streetscape and Landscape Guidelines for Historic Districts. Interest in expanding the proposed standards to Bluff Street was expressed. The Historic Preservation Commission also recommended: 1. That design options be considered for the 1200-1300 blocks of Main Street to allow for street trees with smaller sidewalks and parkways of either green space or the stamped brick pattern. City staff concurs that this is an acceptable alternative in residential areas. Sidewalk Paving Pattern Page 5 2. If owners of property outside of the historic districts would like to request a different sidewalk pattern for their property, they would have to receive approval from the City Council. City staff concurs with the Commission's recommendation. 3. If owners of property in historic districts would like to request a different sidewalk pattern for their property, they would have to have the sidewalk pattern reviewed by the HPC, who then would forward a recommendation to the City Council for final approval. City staff concurs with the Commission's recommendation. What is the projected construction cost? The projected construction cost has been estimated based on the following parameters developed by the Engineering staff: Main Street Pattern Costs: . Buff-colored concrete 11' sidewalk with charcoal paver - $100 a lineal foot. . Quarry red stamped herringbone 8' "bump-outs" - $72 a lineal foot . Tree grates are an extra cost. Side Street Pattern Costs: . Standard grey-colored concrete 6' sidewalk with charcoal paver - $30 a lineal foot. . Brick red stamped herringbone 5' parkway - $45 a lineal foot. Washinqton Park & Public Librarv Costs: . Buff-colored concrete 6' sidewalk with charcoal paver - $54 a lineal foot. . Brick red stamped herringbone 5' parkway - $45 a lineal foot. Standard Pattern Costs: . Standard grey-colored concrete 11' sidewalk - $60 a lineal foot. Average City block - 300 lineal feet. Main Street Pattern: Estimated cost is approximately $100 per lineal foot for the buff-colored sidewalk portion, or about $30,000 for each side of one City block ($100 x 300'). Note: quarry red stamped herringbone "bump-outs" and tree grates are not included in this estimate. Side Street Pattern: Estimated cost is approximately $30 per lineal foot for 6' wide, standard grey-colored sidewalk portion, and about $45 per lineal foot for the 5' wide Sidewalk Paving Pattern Page 6 brick red stamped herringbone parkways. This is a combined cost of $75 per lineal foot, or about $22,500 for each side of one City block. Washinqton Park and Library Sidewalk Pattern: Estimated cost is approximately $54 per lineal foot for the buff-colored, 6' wide sidewalk portion, and about $45 per lineal foot for the brick red stamped herringbone 5' wide parkways. This is a combined cost of $99 per lineal foot, or about $29,700 for each side of one City block. What is the cost to property owners? Downtown sidewalk projects will be installed concurrently with the City's public street improvement program in the Downtown. Amenities also can be installed concurrent with the installation of infrastructure for other Downtown public improvements. Property owners would be assessed for the costs of sidewalk improvements. The following is a typical scenario of the financial impact an enhanced sidewalk improvement could have on a downtown property owner: Average City Block 300' in length Item Standard grey 11' sidewalk ($60 x 300') Buff-colored 11' sidewalk ($100 x 300') Difference Property owner with 50' storefront: Cost for standard grey 11' x 50' sidewalk Cost for buff-colored 11' x 50' sidewalk Difference Property owner with 100' storefront: Cost for Standard Gray 11' x 100' sidewalk Cost for Buff-colored 11' x 100' sidewalk Difference Cost Per Side $18,000 $30,000 $12,000 Cost Per Block $36,000 $60,000 $24,000 $3,000 $5,000 $2,000 $ 6,000 $10,000 $ 4,000 Financial resources for property owners: Property owners would be eligible for the following programs to assist in mitigating the additional costs associated with the enhanced sidewalk improvements. Historic District Public Improvement Proqram (HDPIP): An annual CIP of $100,000 for streetscape and public area improvements in the Historic Districts. The HDPIP provides 3:1 matching grants on a competitive basis to neighborhood associations and neighborhood groups for streetscape improvements in the City's five historic districts. No City funds may be used as match except CDBG funds. Sidewalk Paving Pattern Page 7 The 25% private match may be obtained from assessments of property owners in the project area; private fundraising; private donations; in-kind services; or private, state or federal grants. The HDPIP grant could provide 75% of the additional costs for the enhanced sidewalk treatments for properties in an historic district. Neiqhborhood Grants: An annual CIP of $30,000 for neighborhood improvement projects in CDBG- targeted neighborhoods. Large grants range from $1,000 - $5,000. The Neighborhood Grant could provide the 25% match of the additional costs for the enhanced sidewalk treatments for properties in an historic district using a HDPIP grant. Neiqhborhood Infrastructure Proqram: An annual CIP of $50,000 for repair of public steps and sidewalks, pavement overlays, hand railing and other infrastructure improvements in CDBG-targeted neighborhoods. Financial resources for City projects: ADA Curb Ramp Construction Project: An annual CIP of $55,000 for the installation of ADA compliant curb ramps throughout the city; funded with CDBG money. Repair/Replace Steps/Sidewalks at Library: A one-time CIP to repair and replace sidewalks at the Carnegie-Stout Public Library where needed. Washinqton Park Sidewalks: A CIP for reconstruction of the sidewalks around Washington Park that is not included in the reconstruction of 6th and th Streets, with a budget of $189,000. 6th Street and 7th Street Reconstruction: Reconstruction of both 6th Street and th Street, from Locust Street to Bluff Street has been included in the five-year annual street reconstruction program for about 10 years. The improvement of 7th Street was delayed initially until after the construction of the Dubuque Museum of Art. In addition, there are two public works project related to the Downtown sidewalks - Main Street Historic Lighting (from 1st Street to 5th Street) and the Main Street Overlay CIP (from 1st Street to 5th Street). The Main Street Historic Lighting CIP has a budget of $265,000 to replace the existing lights in the Old Main District with the same historic replica light fixtures installed along Main Street in the Town Clock District. The Main Street Overlay CIP has a budget of $135,000. The overlay project will be reevaluated to determine if it needs to be a reconstruction project. Sidewalk Paving Pattern Page 8 The City will be reviewing opportunities for additional funding in the upcoming five-year CIP budget. Work Session Agenda The agenda for the City Council work session on November 15, 2004 will be: Review large display boards with various sidewalk patterns and aerial photos. Review input City staff sought and what it was. Review budget estimates and funding resources. . Questions and answers.

Discussion Mike Felderman, Civil Engineer, presented the proposed standards, and spoke in favor of the request. He noted that the Engineering Department, working with other City Departments, is proposing to create a paving pattern standard for Downtown sidewalks. He reviewed the proposal to extend the existing Main Street Pattern from 5th to 9th Streets south along Main Street to the Locust Street Connector and north along Main Street to 14th Street. He noted that some of the side streets off of Main Street would have a special sidewalk pattern. He added that the sidewalks around Washington Park and Carnegie Stout Public Library would also have a special sidewalk pattern similar to that found in Flat Iron Park. Laura Carstens, Planning Services Manager, explained that the Historic Preservation Commission is an advisory design review body to the City Council for these types of public improvements in the historjc districts. She added that the City Engineering and Planning staff would like to have an approved standard for sidewalk paving patterns to: 1) Implement a cohesive uniform paving pattern in Downtown, and 2) Enable staff to sign-off on projects that meet the standard. There were no public comments. The Historic Preservation Commission discussed the proposed sidewalk standards. Interest in expanding the proposed standards to Bluff Street and accommodating street tress and green space along parkways was expressed. The Commission commended the Engineering Department for being forward thinking in developing proposed standards for sidewalk paving patterns.
