City Hall Parking Lot Improvements.docx EXECUTIVE SUMMARY City Council Work Session: July 11, 2016 AGENDA ITEM: City Hall Parking Lot Improvements, ENG0174 AGENDA SECTION: Updates PREPARED BY: Mitch Hatcher, Project Engineer AGENDA NO. 3.a. ATTACHMENTS: Parking Lot Design Options APPROVED BY: ddj RECOMMENDED ACTION: Discussion and Direction ISSUE At the June 13, 2016 City Council Work Session staff presented options for the improvements to the City Hall lower parking lot. During discussions two additional options of expanded parking and a modified police entrance were discussed. After further discussion and evaluation, staff is seeking recommendation for the parking lot improvements including the 4 original options presented. BACKGROUND The basic project at the lower City Hall parking lot includes removing the existing pavement and installing 4 inches of new pavement. Four regular parking stalls will be lost due to a change in requirements for larger ADA stalls. The project cost for this work is approximately $200,000. Below are several options for upgrading the existing parking lot based on feedback from the police department and public works staff. The costs provided are in addition to the cost for replacing the pavement in the parking lot. A figure has been provided to illustrate the options. Option 1: Dedicated police entrance: $115,000 Install median within parking lot to establish police entrance 6 new parking stalls are created Install storm sewer to address drainage changes caused by median Install metal railing along the median to restrict pedestrians from walking near garage entrance Option 1 will require the police phone to be relocated to the lower entrance. This is proposed to be completed as a separate project and the cost is unknown at this time. The proposed cost does not address removing or repairing the brick retaining walls on the west and south side of the building. Option 2: Sidewalk Repair: $18,000 Replace sidewalk panels and add ADA compliant ramp near lower doors to City Hall Add ADA compliant pedestrian ramps to the existing sidewalk surrounding the parking lot I:\City Clerk\Agenda Items\Approved Items\3.a. City Hall Parking Lot Improvements.docx 2 Option 3: Improve drainage along north side of City Hall: $15,000 Install a new catch basin at the northwest corner of the building Grade grass area north of City Hall to direct drainage to the new catch basin Option 4: Additional Parking: $79,000 Install 23 new regular stalls and relocate 2 ADA stalls to the north end of the parking lot. Relocate the dumpster to east side of parking lot, north of City Hall. Option 5 and 6 were briefly evaluated and discussed as requested. Option 5 consisted of removing the existing garage building and expanding parking in the northeast corner of the site. The project cost for Option 5 was estimated to be $156,000. Option 6 consisted of modifying the police garage to allow for police vehicles to exit north of the building through the public works area and out to Brazil Avenue. This option would also include removing of the existing garage building. This option would include major modifications to the existing building and extensive excavation and retaining walls. The construction cost of Option 6 was estimated to be upwards of $600,000. Both Option 5 and 6 involves removing of the garage building currently on site, but at this time does not account for the loss of storage and future replacement of the building at a new location. If option 6 was preferred staff would recommend a detailed feasibility report be completed along with additional input from the Facilities Task Force and City Council. After discussions regarding Option 5 and 6, it was determined to move the project forward with the original 4 options as presented at the June 13 meeting. The total cost to replace the pavement in the parking lot and include Option 1, 2, 3, & 4 is $425,000. Pavement replacement can be delayed for several years if Council is comfortable with current condition of the pavement in the parking lot. Delaying the project will not change the scope of the project cost with the exception of construction inflation, or adding additional options in the future. If Council is to authorize plans and specifications and order the project at the July 19, 2016 CC meeting, the design and bidding schedule would allow for a construction start date middle of September with completion by the end of October. Funding for the parking lot improvements is proposed from the Parking Lot Maintenance fund. The current balance of the assigned funds in the Parking Lot Maintenance fund is approximately $729,000. Of this amount, $400,000 is reserved for the improvements of the Community Center Parking Lot in a joint project with the National Guard. The remaining $329,000 could be utilized for the City Hall Parking Lot along with Option 1 with a total estimated cost of $315,000. The additional Options 2, 3, and 4 totaling $112,000 could be funded with the balances available in the Building CIP. SUMMARY Staff is requesting Council review and consideration for proceeding with the development of plans and specifications for the City Hall parking lot and trail improvements.
