City Hall Parking Lot ReconstructTHE CITY OF DUB E ~-~~ MEMORANDUM March 14, 2007 ~.~ ~ ~ TO: The Honorable Mayor and City Council Members .r1 c ~ ~ cn ~ :~ f~ FROM: Michael C. Van Milligen, City Manager D ~: m - N ~ SUBJECT: City Hall Parking Lot Reconstruction CIP 7301843 For the City Hall Parking Lot Reconstruction Project, City Engineer Gus Psihoyos is recommending preliminary approval to the Resolution of Necessity, approval of the Preliminary Schedule of Assessments, establish the date of the public hearing as April 2, 2007, and authorize City Clerk Jeanne Schneider to advertise for bid proposals. The intent is to bid this project two ways. The first is with all concrete. The second is with asemi-pervious brick surface using Purington brick pavers for the parking stalls. The current project estimates exceed the original budget proposal, so additional funding sources were identified. There has not been a funding source identified for the estimated $109,881 in additional cost for the brick pavers. Bid results will help determine the feasibility of adding these brick pavers. I concur with the recommendation and respectfully request Mayor and City Council approval. '~, ~ , Mic ael C.

Van Milligen, City Manage FROM: Gus Psihoyos, City Engineer --~ ' SUBJECTS: City Hall Parking Lot Reconstruction Project CIP 7301843 INTRODUCTION The enclosed resolutions authorize the public bidding procedure for the City Hall Parking Lot Reconstruction Project. BACKGROUND The City Hall Parking Lot was last reconstructed in 1981. At that time the pavement was resurfaced using asphalt pavement. DISCUSSION The City Hall Parking Lot Reconstruction Project will provide for the reconstruction of underground utilities, adjacent sidewalks, perimeter lighting, parking lot sub-base and the construction of new 7" thick concrete pavement. The project will also provide for the installation of new perimeter fencing that complements the historical features of City Hall. All existing overhead electric lines and services will be transferred to underground. The existing generator and electrical cabinets would be screened with an enclosure that matches the proposed perimeter fencing. The project will include utility upgrades and repairs that include: • The reconstruction of 3 deteriorated brick manholes • The reconstruction of approximately 520 lineal feet of watermain, mainline valves, fire hydrants, and the replacement of 3 lead commercial water services. The cost of the individual lead commercial water service replacements will be assessed to each respective private property owner. • The project also provides for the construction of approximately 135 lineal feet of new storm sewer and 2 catch basins to complement bioswales that are proposed for the medians. • The installation of fiber optics and telecommunications conduit infrastructure are proposed to improve connectivity with City Hall. This will include 485 lineal feet of 4" conduit with inner ducts and the construction of two fiber optic manholes. • The installation of 6 electrical service pedestals and 6 water lawn hydrants to provide for the future electrical and water needs for Farmer's Market and other festivals. The sidewalks are proposed to be replaced with new decorative buff colored sidewalk that follows the downtown decorative sidewalk standard. The sidewalks would be illuminated at night by historic pedestrian lighting. These pedestrian light poles would be placed around the perimeter of the parking lot. In addition, electrical service pedestals and water hydrants would be placed around the perimeter of the parking lot similar to those installed at Washington Park. This would serve the future power and water needs for festivals and Farmer's Market. The Engineering Department has coordinated with the Leisure Services department to design landscaping for the parking lot that will allow for the installation of bioswales. The purpose of the bioswales is to intercept the storm water prior to entering the storm sewer system so as to allow for a large percentage of the impurities to be filtered out. Parking lots tend to have a lot of impurities such as oil residue, antifreeze, metals, etc. The bioswales provide the appropriate vegetation to allow for the removal of these impurities prior to them entering the storm sewer and ultimately the Mississippi River. An alternate is also proposed for this project to allow for the City of Dubuque to receive bids on the option of reusing purington brick pavers for the parking stalls. This alternate would provide for the ability to recycle old pavers formally used on City streets and use them as part of the paving surface of the parking lot. The pavers would provide for a semi-pervious paving surface that would help recharge the existing water aquifer, minimize runoff and improve the water quality of the runoff. Currently it is anticipated there will not be sufficient funding to support this alternate based on the engineer's estimate. If favorable bid prices are received, this alternate can be considered for inclusion in the project. An additional alternate is also being proposed. This alternate would provide for the installation of heat tubes in the sidewalk along the 13th side of City Hall. The heat tubes would be installed to provide for the future connection to a heat pump. The system when connected and operational would provide snow melt capacity similar to what is currently in place on the east side and west side of City Hall. This alternate only provides for the installation of the heat tubes and does not provide for a fully functioning snow melt system at this time. PROJECT COORDINATION This project would occur concurrently with the City Hall Envelope Restoration (Tuckpointing) Project. City staff will coordinate the construction activities to minimize disruption to this project. Staff also will be coordinating with Dubuque Main Street Ltd. To minimize disruption to Farmer's Market. City staff will also work with Thompson Properties (Okey Dokey Food Market and Breezy's Cafe) to minimize disruption of their businesses during the construction of the parking lot and alley behind the businesses. PROJECT SCHEDULE The schedule for the project is as follows: Initiate Public Bidding Process Publish Public Hearing Notice on Plans, Specs, Assessments Mail Special Assessment Notice to Property Owners Publish Notice of Special Assessment: 1st Publication: 2nd Publication: Publish Notice to Bidders, Advertise for Bids Public Hearing on Plans & Specs, Spec.

Projects 19,942.73 Total Project Funding $ 838,477.55 The City Hall Parking Lot Reconstruction Project will be funded through the annual capital improvement project appropriation of City funds as noted above in the amount of $832,473.67. The project, as outlined, will require Special Assessments in the amount of $6,003.88. An alternate is proposed to use recycled purington pavers in the drive stalls of the parking lot. If this alternate is selected, it is currently estimated that it would cost an additional $109,881. There currently isn't sufficient funding to support this alternate. Favorable bid prices could change that however. PROPERTY ASSESSMENTS Three private lead water services are proposed to be replaced as part of this project. The three services currently serve the Thompson Properties Buildings (Oky Doky Food Market and Breezy's Cafe). These services would be directly assessable to the property owner who would bear 100% of the cost for these services. ACTION TO BE TAKEN The City Council is requested to give preliminary approval to the Resolution of Necessity; approve the Preliminary Schedule of Assessments; to establish the date of the public hearing; and to authorize the City Clerk to advertise for bid proposals through the adoption of the enclosed resolutions for the City Hall Parking Lot Reconstruction.
