Van Milligen, City Manager SUBJECT: 11th Street Steps & Grove Terrace Retaining Wall Reconstruction Project CIP: 2501029 -Stone Retaining Walls 3002022 -Foye/Merchants/Gold Street Reconstruction Historic Preservation Fund DATE: July 17, 2008 Sealed bids were received on the 11t" Street Steps and Grove Terrace Retaining Wall Reconstruction Project. City Engineer Gus Psihoyos is recommending award to the low bidder, Portzen Construction, in the amount of $589,175.50. This is 15.8% over the engineer's estimate. There was only $259,239 available in the City budget for stone retaining walls.

DISCUSSION The final design of the Grove Terrace Retaining Wall Project includes the installation of concrete backfill and geofoam blocks to limit the stresses on the new retaining wall and allow the reuse of a significant portion of the existing limestone block. The project will also include installation of reinforced concrete over the existing 11th Street stairs arch to stabilize the arch. The section of Grove Terrace around the stairs will be reconstructed with 7" concrete pavement with integral curb and gutter. The rest of Grove Terrace will be reconstructed with asphalt pavement and concrete curb and gutter. The existing 8" sanitary sewer will be reconstructed along with the replacement of 2 sanitary manholes. The 11th Street stairs retaining walls will be partially reconstructed with salvaged limestone blocks and new limestone. The stairs will be partially reconstructed along with the replacement of some handrail and the refurbishing of the remaining railing. Wrought iron hoop railing will be installed at the top of the stairs. The installation of a new historic street light will help illuminate the stairway and provide for roadway lighting at the top of the stairs. Because the project is in the 11th Street historic neighborhood, Engineering staff will be presenting an overview of the project to the Historic Preservation Commission on July 17 for concurrence.

Gus Psihoyos, City Engineer SUBJECT: 11th Street Steps & Grove Terrace Retaining Wall Project CIP: 2501029 -Stone Retaining Walls, 3002022 - Foye/Merchants/Gold, Historic Preservation Funds DATE: June 30, 2008 INTRODUCTION Dubuque Aq-Ame~caCinl r 2007 The enclosed resolutions authorize the public bidding procedure for the 11T" Street Steps & Grove Terrace Retaining Wall Project. BACKGROUND In the West 11th Street Historic District, there is a City-owned limestone retaining wall around the 11th Street stairs at Grove Terrace that was known to be in deteriorating condition. Last year the Engineering Department noticed that the walls around the 11th Street steps were bowing and showing signs of distress. IIW Engineers & Surveyors PC (IIW) was hired to investigate the structural integrity of the walls and stairs. Preliminary plans were developed and engineering staff went before the Historic Preservation commission in December 2007 for a design review. City staff reviewed the comments made at that HPC meeting and directed IIW to incorporate those changes in subsequent plans. When the engineering staff was prepared to go to bid for the stairs and related retaining wall repairs, the retaining wall on Grove Terrace failed on April 1St, 2008 just north of the original project limits. Due to the record snowfall and heavy rains this spring, the structural integrity of the wall, Grove Terrace, and utilities were severely compromised. For public safety, this area has been closed to vehicular/pedestrian traffic since the initial collapse on April 1. In the interest of public safety, the resident of 1108 Grove Terrace had limited access to his home for approximately 7 days and the residents of the Teresa Shelter on Bluff Street were evacuated to temporary housing for a period of 2 weeks. On May 7, Tschiggfrie Excavating was hired on an emergency basis to begin the wall deconstruction work. This work included: the removal of a wall section and native earth material back to the existing rock shelf and natural bluff; the placement of plastic sheeting over the exposed slopes and temporary curbs to redirect water away from the excavated area; and the temporary bypass of the sanitary sewer on Grove Terrace to Bluff Street. Also, since the initial wall collapse, IIW was hired to provide ongoing inspection and to assist in the design of a replacement wall system. For the past two months the engineering department and IIW have discussed a comprehensive repair for the Grove Terrace retaining wall and the 11th Street Stairs. The final design includes the installation of concrete backfill and geofoam blocks to limit the stresses on the new retaining wall and allow the reuse of a significant portion of the existing limestone block. The project will also include installation of reinforced concrete over the existing 11th Street stairs arch to stabilize the arch. The section of Grove Terrace around the stairs will be reconstructed with 7" concrete pavement with integral curb and gutter. The rest of Grove Terrace will be reconstructed with asphalt pavement and concrete curb and gutter. The existing 8" sanitary sewer will be reconstructed along with the replacement of 2 sanitary manholes. The 11th Street stairs retaining walls will be partially reconstructed with salvaged limestone blocks and new limestone. The stairs will be partially reconstructed along with the replacement of some handrail and the refurbishing of the remaining railing. Wrought iron hoop railing will be installed at the top of the stairs. The installation of a new historic street light will help illuminate the stairway and provide for roadway lighting at the top of the stairs.

The staff report and related materials are attached for your review. Background The project includes the repair and reconstruction of the W. 11t" Street stairs and the Grove Terrace retaining wall. On January 22, 2008 City Council approved $90,000 in HDPIP funds for the W. 11t" Street stair project. No HDPIP funds are requested for the Grove Terrace retaining wall project. Both the stairs and the retaining wall are in the W. 11t" Street Historic District, where the HPC conducts advisory design review for public works projects. Discussion The W. 11t Street stairs project will involve the removal of the street pavement on Grove Terrace around the upper portion of the 11th Street stairs, excavation above the existing arch, installation of a reinforced concrete bridge with ties to hold the existing arch in place, reshaping of the existing roadway subgrade to correct drainage deficiencies, installation of new curb and gutter and limestone barrier wall, installation of new concrete pavement and installation of new decorative fencing. The existing retaining walls along the 11th Street stairs will be repaired using native Dubuque limestone and properly tuckpointed. Existing materials will be used as much as possible with new materials matching the existing materials in size, color and material type. A historic pedestrian light is proposed to be placed at the top of the stairs on Grove Terrace. This will provide illumination for the upper portion of the stairs and Grove Terrace. The existing lighting under the arch will remain in place. The Grove Terrace Retaining Wall will be reconstructed using existing limestone block that was salvaged from the wall failure. New limestone block will be cut and placed where needed. The dimensional size of the new limestone will match the existing retaining wall block. Behind the new limestone the wall will be backfilled with W. 11th Street Stairs and Grove Terrace Retaining Wall Projects F:\Users\Djohnson\Council Items\W. 11th Street Stairs and Grove Terrace Retaining Wall Projects\Council Letter Page 2 reinforced concrete and Geofoam blocks. The Geofoam blocks are a high density styrofoam block that reduces the lateral earth pressure on the retaining wall and allows the use of less limestone (and reduces cost). Grove Terrace will be reconstructed with 7" concrete pavement around the stairs and behind the retaining wall. Asphalt pavement will be placed to match up with the existing pavement of Grove Terrace on each end of the project. Recommendation By a vote of 7 to 0, the Historic Preservation Commission recommends City Council approve the repair and reconstruction of the W. 11th Street stairs and Grove Terrace retaining wall projects with the condition that the coursework is horizontal, the proposed light fixture be centered in front of the tunnel, and the tunnel be up lighted. A simple majority vote is needed for the City Council to approve the request. Respectfully submitted, ~liGt-` Christine Olson, Chairperson Historic Preservation Commission Enclosures cc Gus Psihoyos, City Engineer A®VIS®RY ®ESIGV~ REll9EW STAFF REP®R`~ ftfleetirtg ®ate: July 17, 2®®8 Pr®perty Address: W. 11t" Street Stairs & Grove Terrace Retaining Wall Property ®wner: City of Dubuque Applicant: ~ City of Dubuque Pr®ject: To repair and reconstruct the W. 11t" Street Stairs.and Grove Terrace Retaining Wall. Hist®ric Preservati®r~ ®istrict: W. 11th Lartdmarl~: No Funding: HDPIP (Stairs) ®ate Built: 1883 Present ,arid Use: Public Physical Characteristics: A massive stone vaulted tunnel marks the point where the West 11t" Street Elevator passed through the wall. Today a recessed shaft located at the center of Grove Terrace and on the West 11t" Street right-of-way, marks the point where the Elevator continued up and out of that tunnel and above grade up to Highland Place to the west. The West 11t" Street Stairs, of concrete construction, now parallel the former course of the Elevator. They extend from Bluff Street to the east, up the bluff front, through the tunnel and along the south side of the retaining wall that defines the bluff that fronts east behind the houses along Grove Terrace. l~arrative Statement ®f Significance: The City of Dubuque West Eleventh Street Historic District takes its name from the Eleventh Street Elevator. In 1877, it was noted that it was becoming increasingly desirable to build and live on the Bluffs and many downtown people were moving to the bluffs. The trend inspired the establishment of the Julien Avenue Railroad Company, which, despite a 25 year charter from the city, never ran a car up the bluff. The real success and inspiration to those who resided on the Eleventh Street Hill was that of Jesse Farley's private inclined railway service. Farley started his own service in 1883 and then started letting neighbors ride for a quarter. By the mid-1880s it was a success and survived numerous fires. In 1887 the Eleventh Street Elevator Company was established, began service in 1888, and began to use electrical power in 1890. The Eleventh Street Elevator differed structurally from the 4t" Street model because it was elevated high above the ground surface. The upper station was at Highland Place. The wealthy residents on Grove Terrace were less than pleased with the noise from the operation and in mid-1895 the company put rubber tires on the cars. The Herald reported at least temporary success, "the noise is hushed, neighbors satisfied and babies sleep sweetly and undisturbed again." Already by 1889 the elevator was being hailed as "a great convenience to residents on the hill"with a magnificent view that made it "a place of public resort not only by residents but for strangers visiting the city". Due to financial difficulties, the elevator was finally abandoned in 1927 and concrete steps now pass through the surviving arch. Staff Analysis: ~/. 99th Street Stair Project: This portion of the project will utilize $90,000 in HDPIP funds. City Council approved allocation of these funds to the W. 11t" Street Stair project on January 22, 2008. Advisory Design Review/HDPIP - W. 11t" Street Stair & Grove Terrace Retaining Wall Page 2 On September 20, 2007, the HPC reviewed and tabled the advisory design review for the repair and reconstruction of the W. 11t" Street stair project to a future meeting and requesting the Engineering Department evaluate the following options which are shown in bold. The City of Dubuque Engineering Department's response to the options is shown in italics. 1) Excavate the fill under the arch, remove the north facing stair, and consider a straight run of stairs. Historical photos show the stairs pretty close to their current configuration. It would also be cost prohibitive to replace the whole lower portion of the stairs and have them go straight out from the arch. 2) Limestone co~arseworl~ to run horizontal. The limestone course work will match what exists. Since the work involves replacing portions of the walls, we have to match the existing coursework. 3) ~p~light the arch instead of the pedestrian Sight fixture at the stair land'ang at the base of the arch. The light was moved to the top of Grove Terrace to provide security lighting to the top of the stairs and illuminate Grove Terrace. Engineering will look at an alternative way to illuminate the arch. This will probably be handled as a change order during the project. 4) combine the proposed decorative hoop railing with the existing style of handrail on the stair. The decorative hoop railing will be used along Grove Terrace at the top of the stairs. Limestone will be placed 2 feet above the street with the hoop railing above it to provide a crash barrier for cars. The existing style of hand railing will be used for the stairs due to cost and usability. The hoop railing is not very conducive as a hand railing on stairs. 5) A trash container is located at the bottom of the stairs. Engineering will coordinate the placement of a trash container at the bottom of the stairs. It will match the style we currently use in the historic districts. The proposed work will involve the removal of the street pavement on Grove Terrace around the upper portion of the 11th Street stairs, excavation above the existing arch, installation of a reinforced concrete bridge with ties to hold the existing arch in place, reshaping of the existing roadway subgrade to correct drainage deficiencies, installation of new curb and gutter and limestone barrier wall, installation of new concrete pavement and installation of new decorative fencing. The_ existing retaining walls along the 11th Street stairs will be repaired using native Dubuque limestone and properly tuckpointed. Existing materials will be used as much as possible with new materials Advisory Design Review/HDPIP - W. 11t" Street Stair & Grove Terrace Retaining Wall Page 2 matching the existing materials in size, color and material type. A historic pedestrian light is proposed to be placed at the top of the stairs on Grove Terrace. This will provide illumination for the upper portion of the stairs and Grove Terrace. The existing lighting under the arch will remain in place. The estimated project cost for the stairs portion of the project is approximately $200,000. Grove Terrace Retaining Wall: The Grove Terrace Retaining Wall will be reconstructed using existing limestone block that was salvaged from the wall failure. New limestone block will be cut and placed where needed. The dimensional size of the new limestone will match the existing retaining wall block. Behind the new limestone the wall will be backfilled with reinforced concrete and Geofoam blocks. The Geofoam blocks are a high density styrofoam block that reduces the lateral earth pressure on the retaining wall and allows the use of less limestone (an reduces cost). Grove Terrace will be reconstructed with 7" concrete pavement around the stairs and behind the retaining wall. Asphalt pavement will be placed to match up with the existing pavement of Grove Terrace on each end of the project. The construction cost for this portion of the work amounts to approximately $400,000 and the estimated completion date is the summer of 2008. The Grove Terrace retaining wall will not use HDPIP funds. 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 at landmark sites. The Commission's recommendation will go on to the City Council with the application materials for their review and approval of the project. Minutes from the September 20, 2007 meeting are enclosed. Also enclosed are historical photographs of the stairs and plans for the projects prepared by IIW Engineers & Surveyors. Compliance with Guidelines: In 2002, the Streetscape and Landscape Guidelines were created to help provide recommendations for public improvements on public property.

He stated slate was a very popular material on the larger, high style homes, and original materials should be retained and repaired whenever possible. He explained the guidelines state these materials can be prohibitively expensive, however, and substitute materials may be acceptable, if installed properly. He explained the guidelines suggest that if the original materials are no longer present, a severely deteriorated, or prohibitively expensive, substitute material, such as fiberglass, metal, or architectural asphalt shingles are acceptable. New materials should attempt to match the original in color, size and shape. He stated new asphalt or fiberglass material should be appropriate in color, such as black, gray, or dark brown. Dark red, blue/gray, and dark green are also appropriate if replacing slate or tile. The Commission questioned the percentage of roof that was slate. Mrs. Souto stated approximately 50% of the material on the mansard roof was slate prior to EIC Roofing removing the material. The Commission discussed the color and style of the shingles on 1655 Main Street and similar homes. Mr. Souto explained they would like to install laminated asphalt carriage house-style shingles on the mansard roof like those on the Ryan House, except in gray. Mr. Souto distributed photographs of mansard roofs found in Dubuque with the carriage house-style shingle that they want to install on 1655 Main Street. Motion by Wand, seconded by Bichell, to approve a Certificate of Appropriateness to install the laminated asphalt carriage house-style shingles as presented and gray in color. Motion carried by the following vote: Aye -Whalen, Olson, Wainwright, Bichell, Wand, Lundh and McDonell; Nay -None. ADVISORY DESIGN REVIEW: Request by City of Dubuque for Advisory Design Review of the project to repair and reconstruct the W. 11th Street Elevator/Stairs located at W. 11 t" Street in the W. 11 t" Street Historic District. Jon Dienst, City Engineering Department, reviewed the project. He described the project involves partial reconstruction and repair of the stairs and repair of the railing at the top of the West 11 t" Street stairs. He explained the project will involve the removal of the street pavement on Grove Terrace around the upper portion of the 11t" Street stairs, excavating above the existing arch, installation of a reinforced concrete bridge with ties to hold the existing arch in place, reshaping of the existing roadway subgrade to correct drainage deficiencies, installation of new curb and gutter and limestone barrier wall, installation of new concrete pavement and installation of new decorative fencing. The existing retaining walls along the 11t" Street stairs will be repaired and replaced where needed using native Dubuque limestone and proper tuckpointing. He explained the existing materials will be used to the greatest extent possible with new materials to match the existing materials in size, color and material type. He explained a historic pedestrian light is proposed to be placed along the sidewalk below the arch to provide illumination for the lower portion of the stairs as well as illuminate under the arch itself. He explained the City would like to begin this project in the spring of 2008 Minutes -Historic Preservation Commission September 20, 2007 Page 3 with an estimated completion date in the summer of 2008. He explained by removing the street above the arch and installing a concrete bridge to support the street over the arch, the arch will no longer support the weight of the street, consequently strengthening the arch. He explained that decorative hoop railings with limestone pillars will be installed at the top of the stairs. He explained the limestone pillars would be a bid alternate. He explained Engineering is also proposing a decorative pedestrian light on the limestone pillar to illuminate the arch and stairs. Commissioners discussed how the storm water will be handled. Commissioners reviewed which walls will be repaired and replaced. Staff Member Dienst explained how drain file will be installed and how the entrance at Grove Terrace will be changed. He noted the current stair entrance on Grove Terrace will be moved 90 degrees, and a vehicle barrier will be added. In response to the question by the Commission, Staff Member Dienst noted the course work will be horizontal and the plans are incorrect in this respect. He noted the project will take about two months and will block the entrance to one property. The Commission requested a trash can be added at the base of the arch. Staff Member Dienst explained that the existing rail would be sandblasted, painted and re-used where possible. The Commission requested that a more decorative hand rail or re-use of the existing rail with the hoop rail behind it. Staff Member Dienst explained that Engineering will evaluate how far the railing will be repaired and replaced, and a decorative railing may be a bid alternate. The Commission suggested using the decorative hoop railing proposed on the top of the stair entrance as the decorative rail to be used along to the stairs. Staff Member Dienst confirmed the existing arch supports will be cleaned and painted. The Commission discussed the proposed lighting at the base of the arch. The Commission recommended the historic pedestrian light fixture proposed at the stair landing at the base of the arch be relocated and fixed atop another of the proposed stone pillars. The Commission recommended discretely located and historically appropriate light fixtures to up-light and illuminate the under side of the arch as an alternative to the pedestrian light fixture. The Commission explained that would be a preferred lighting alternative since a pedestrian light fixture near the stair landing at the base of the arch would create an interruption in the sight line and distance as you look up or down through the arch. The Commission emphasized the lighting would have to be evenly distributed under the arch. The Commission discussed moving the switch back of the stairs under the arch. The Commission discussed the previous location of the West 11 t" Street elevator in relation to the stairs. Staff Member Dienst confirmed the stairs will follow the current alignment and be built to City Code. The Commission discussed whether the stairs could be rebuilt with a straight run without the dog leg by removing fill under the arch. The Minutes -Historic Preservation Commission September 20, 2007 Page 4 Commission discussed the added cost of excavation and removal of the north facing stairs. By consensus, the Commission tabled the Advisory Design Review for the repair and reconstruction of the West 11 t" Street stairs to a future meeting and requested Engineering evaluate the following options to be presented to the Commission at a later date: 1) Excavate the fill under the arch, remove the north facing stair, and consider a straight run of stairs. 2) Limestone coursework to run horizontal. 3) Up-light the arch instead of the pedestrian light fixture at the stair landing at the base of the arch. 4) Combine the proposed decorative hoop railing with the existing style of handrail on the stair. 5) A trash container be located at the bottom of the stairs. ITEMS FROM PUBLIC: Envision 2010 Rail Committee: The Commission discussed the memorandum from the Envision 2010 Rail Committee requesting support in bringing passenger rail service back to Dubuque. Motion by Bichell, seconded by McDonell, to direct staff to write a letter of support to bring passenger rail service between Dubuque and Chicago. Motion carried by the following vote: Aye -Whalen, Olson, Wainwright, Bichell, Lundh, Wand and McDonell; Nay -None. ITEMS FROM COMMISSION: Elect Vice Chairperson: The Commission discussed electing a new vice chairperson. Commissioner Wand stated the new vice chairperson should be someone who has not served as vice-chairperson or the chairperson of the Commission. He explained the vice chairperson position should be filled by a commissioner who would like to eventually become chairperson. Motion by Wainwight, seconded by Bichell, to nominate Commissioner Lundh to be vice chairperson for the Historic Preservation Commission. Motion carried by the following vote: Aye -Whalen, Olson, Wainwright, Bichell, Lundh, Wand and McDonell; Nay - None. HPC Meeting Location: The Commission discussed where future Historic Preservation Commission meetings will be located, given the recent renovation to the Historic Federal Building.
