2.1.a City of Boise FY 2017 Interim Changes September 19, 2017 Expenditure Changes 1. Airport (Airport Fund) Baggage System Upgrades: $60,000 (one-time) The Airport requests a $60,000 appropriation increase to the Baggage System Upgrade capital project which will bring the total project cost to $9,164,484. This project consists of a complete replacement of the old baggage system to accommodate the new TSA screening devices. There has been an issue with bags not being placed on the conveyor belts correctly which causes bags to get outside of their designated space on the conveyor which ultimately results in a missing bag (not in its designated space on the conveyor) or an unidentified bag (the bag located somewhere else on the conveyor). This leads to more work by the TSA to investigate what is going on and manually checking the bag. In order to correct this problem, the project management team has identified several items that need to be modified. This will result in the baggage system running more efficiently and the bags moving through the system more quickly. The Airport plans to fund this with cash reserves at this time as it is uncertain if this will be a reimbursable item by the TSA. Source/Use Fund Dept/Org Acct.

Parks & Recreation (Foothills Levy Fund) Foothills Land Acquisition: $100,120 (one-time) Parks & Recreation requests approval for a $100,120 capital project and its corresponding expenditure appropriation for the purchase of approximately 25 acres located in the Boise Foothills funded by the Foothills Levy. The land is north of Warm Spring Blvd, west of Highway 21 and adjacent to the Boise River Wildlife Management Area. The purchase of this property has been made possible by significant contributions from Barber Valley Neighborhood residents, support from the Idaho Shakespeare Festival, the Idaho Fish and Wildlife Foundation, the Land Trust of the Treasure Valley, and many others. This land will expand existing protected wildlife habitat and provide a unique opportunity to engage residents in wildlife education and protection.

2.1.a 3. Public Works (Geothermal Fund) Expenditure Adjustments: $100,000 (one-time) Public Works requests approval for a $100,000 expenditure increase in the Geothermal Fund to reflect non-cash accounting adjustments and higher than anticipated legal costs. In August of FY 2017, nearly $40,000 in accounting adjustments were recorded in the financial statements for assets write-offs. While there is no economic impact to these transactions, they reduced the budget available for operations. Legal fees were also larger than had originally been estimated. This budget increase would avoid the inability to pay vendors because of system constraints. The Geothermal fund has an adequate fund balance to absorb the increase and anticipates finishing the year with a surplus. Source/Use Fund Dept/Org Acct.

2.2.a TO: Mayor David H. Bieter and Boise City Council FROM: Zach Piepmeyer, PE CC: David Corcoran, AICP (ACHD) DATE: 9/13/2017 RE: ACHD State Street & Pierce Park Intersection DESCRIPTION OF ISSUE ACHD is performing concept analyses for the future widening and realignment of the intersection of State Street & Pierce Park Lane. This memo provides an overview of the project, a description of the recommended intersection design, a list of key project design elements being considered for the intersection and identifies some future considerations for the City. A map of the intersection showing proposed improvements is included at the end of this memo. PROJECT OVERVIEW The intersection of State Street and Pierce Park Lane currently exhibits a substandard 50- degree intersection skew angle. This angle presents visibility and safety concerns for all users of the intersection, including cyclists, pedestrians and motorists. The ACHD project intends to modify the intersection angle to approximately a right angle to mitigate the safety concerns. As with other intersection projects in progress on the State Street corridor, this project also intends to widen State Street to seven lanes (3 lanes each direction with a center turn lane or median) in accordance with the adopted State Street Transit & Traffic Operations Plan (TTOP). The proposed State Street TTOP typical section is as shown below. Packet Pg. 4
2.2.a State Street TTOP Typical Section The State & Pierce Park project will extend from Hertford Drive to Ellens Ferry Drive (0.7 mile on State Street). The western limits of this ACHD project will likely tie directly into improvements proposed through the ITD State & Glenwood project proposed to the west. A construction date for the State & Glenwood project has not yet been formalized. The State & Pierce Park intersection project schedule is as follows: 2017 Concept Study/Design 2018 Final Design 2019 Right-of-Way Acquisition 2020 Construction Note: Construction of State/VMP is in 2018 and construction of State/Collister is in 2019. KEY PROJECT DESIGN ELEMENTS The following design elements are proposed by ACHD staff to be incorporated into the project. These items are identified on the attached map. The PDS team concurs with all of these proposed elements. 1. East side crosswalk at State/Pierce Park: Project to include a State Street crossing on both the east and west approaches to Pierce Park. Dual crosswalks will aid pedestrian mobility, particularly with respect to the proposed far-side transit stops. 2. WB-to-EB State Street U-turn on the eastern approach. This U-turn will be positioned slightly east of the intersection such that there is physical separation between the U-turning traffic and the pedestrian refuge in the middle of State Street for the eastern State Street crosswalk. 3. WB-to-EB State Street U-turn west of Lakeside Drive. This U-turn will provide access to residences on the south side of State Street as well as Plantation Golf Course. Page 2 of 4 Packet Pg. 5
2.2.a 4. Three Quarter Access at State/Hertford Drive: The median on State Street will be designed to permit right-in, right-out and left-in turning movements at Hertford Drive on the western edge of this project. Only left-out turns will be prohibited at this intersection. 5. EB-to-WB State Street U-turn at Ellens Ferry. This U-turn will provide improved access to businesses on the north side of State Street. FUTURE CONSIDERATION LANDSCAPE BUFFER WIDTH AND LANDSCAPING IN THE ACHD RIGHT-OF-WAY The City of Boise requested detached sidewalks be considered on the north side of State Street and on Pierce Park (Note that the attached concept design does not yet show detached sidewalk on Pierce Park). Garden City also requested detached sidewalks on the south side of State Street. Detached sidewalks provide a buffer between the proposed sidewalk and roadway that can be landscaped. This landscaping and physical separation from the roadway provide safety benefits to pedestrians as well as aesthetic benefits. Landscape buffer widths are 6-8. The standard 6 landscape buffer will be applied by ACHD unless the City requests the 8 buffer and enters a Cost Share Agreement for additional right-ofway costs associated with the larger project footprint. An 8 wide buffer permits the planting of Class II trees without root barrier. There are two project design elements that have the potential to impact landscaping within the proposed buffers. Both items still need to be evaluated by the ACHD design team during the remainder of the Concept Phase: Existing overhead utilities may need to be placed within the landscape buffer on the north side of State Street and east side of Pierce Park. If so, this will preclude placement of Class II trees within the landscape buffers at these locations. A portion of the proposed landscape buffer space may need to be utilized by ACHD for storm drain facilities. This may impact the type and amount of plant material that can be implemented in these areas. Buffer width and landscaping within the ACHD right-of-way will be brought back to the Council at a future date for consideration. PDS TEAM RECOMMENDATION Implement items 1-5 identified above under Key Project Design Elements Implement detached sidewalks on both sides of Pierce Park Ensure that overhead utility locations, storm drain facility locations, and landscape buffers are fully evaluated and identified in the final ACHD Concept Report for this project Page 3 of 4 Packet Pg. 6
2.2.a REQUESTED ACTION Please provide feedback on the recommended intersection design during the September 19 Boise City Council Work Session. NEXT STEPS ACHD staff will present the City s feedback to the ACHD Commission and incorporate into the Concept Report. ACHD will then formally adopt the preferred design and the Concept Report will be finalized in October 2017. Final Design is anticipated to begin in early 2018. Page 4 of 4 Packet Pg. 7
