Without the grant for Phase 3 and in order to complete the entire highway, we will have to change the scope of the project to a budget of only $9.5 million. We may however be able to include additional monies from WSDOT and bring the budget to $12.5 million. Funding with or without the WSDOT contribution will require a change in project scope and approval from Council. We will then direct the current design to include any changes. TO: FROM: DATE: SUBJECT: INFORMATION MEMO Mayor Mullet Public Works Directo}IIJJ January 22, 2004 Tukwila International Blvd. Phases 2 3 (S 116 St to S 138 St) Scope and Budget Alternatives Project No. 95 -RWO3 ISSUE Present scope alternatives based on secured funding and potential funding from WSDOT. BACKGROUND This project was presented to Transportation Committee in February 2003 where project limits were discussed. The resulting consensus was the preference to complete roadway improvements from the north limit of Phase 1 (S 138 St) to as far north as possible with the available funding (just north of the Sabey development). This would eliminate having a "gap" in improvements where Phase 3 is currently identified. The City has subsequently learned about a WSDOT funded project that overlaps the City's Phase 3 project and a portion of Phase 2. City staff is in discussions with WSDOT to transfer state funds to the City to complete all desired /needed improvements with one project managed by the City. KPG, Inc., is under contract with the City to design Phase 2 of T.I.B. improvements. They have developed scope and budget alternatives for the project limits from S 138'" St to S 116t St based on the different funding scenarios. The estimated costs with descriptions of included and excluded scope items are shown in the attached spreadsheet. ANALYSIS All alternatives are based on the same project limits from S 138 St to S 116t St. The scopes and budgets shown are based on: 1) the original information developed within the design report, 2) the current secured funding, and 3) the current funding plus the budgeted state funds. The description shown for each funding alternative identifies scope items that are assumed to be included or excluded in order to fit within each estimated budget. RECOMMENDATION Discuss the alternatives presented and provide direction to staff on desired scope items in order to proceed with design of improvements. attachment: Scope and Budget Alternatives (P:Projee¢U- RW RS ProjectsW5RW03 TIR2 \Memo Phase 2 Alts) Tukwila International Boulevard Phase II and III South 138th STreet to South 116th Street Scope and Budget Alternative December 12, 2003 Underground all aerial utilities New Illumination system 5 lane roadway section 4" planters with 8' sidewalks both sides provide medians where left turn access is not required 4" planter with 8' sidewalk on west side for pedestrian connection to the Green River trail No undergrounding - pole relocations only Illumination on relocated utility poles Transition to 4 lane section at Southgate and Riverton Creek crossings to reduce wall costs Typically 4' planters with 6' sidewalks reduce to 6' sidewalk and no planter in some locations to reduce wall costs Minimal medians Use roadway shoulder for pedestrian connection to Green River Trail No undergrounding - pole relocations only Budget would allow a new illumination system 5 lane roadway section 4' planters with 6' sidewalks both sides provide medians where left turn access is not required Curb or planter separation for pedestrian connection to Green River Trail JL 11 2.004 C.I.P. in PHASE1 PHASE 2 PHASE 3 S I \LL City of Tukwila Tukwila International Boulevard Design Report Section 1— Executive Summary ['Lc NTS JI Tukwila International Blvd. Report Vicinity Map Transportation Committee January 26, 2004 DRAFT Present: Joan Hernandez, Chair; Pam Carter; Joe Duffle (arr. 6:15) Jim Morrow, Brian Shelton, Bob Giberson, Ryan Partee, Cyndy Knighton, Gail Labanara, Robin Tischmak, Lucy Lauterbach; Brent Carson- Westfield Mall 1. Tukwila International Boulevard Because the City did not receive a $4 million grant from TIB they were hoping for, Phase 3 of TIB is short of funding. To address the issue, the department decided to combine KPG's Phase 2 and 3 designs to see what kinds of savings they could get. They showed the Committee some options they have found thus far. As undergrounding costs are very high, the option saving the most money does not include undergrounding from about S. 139` north on the highway. To do the two projects together with only Tukwila money, one lane would be taken out in parts, with no planters in some positions, and a road shoulder to get to the river. However, it is possible we will be able to use some WSDOT fluids they had scheduled for using in the same area. If so, though there would still be less undergrounding than if full funding were available, but five lanes would be maintained, and medians would be put in where there are no left turns. The Committee agreed that changing the undergrounding ordinance would be a policy decision the Council would need to make before we could consider option 2 or 3. Joan said that topic is an item on the Council Retreat Agenda. Information 2. Transportation Imnact Fees A recent court case showed that the City needs to formalize its impact fee process. The long -term goal will be to change the Transportation Concurrency ordinance. For now they have devised a table with impact fees based on the methodology in the current comp plan. They showed the cost for several sections of roadway or intersections calculated according to the RCW. Cost ranged from $280 /trip to $12,900 for the most expensive cost/trip. Trips are calculated on the number of 4 -6 p.m.weekday peak trips. When asked what other cities did, Cyndy said there is a large range of costing methods. Some cities have a flat fee, and others negotiate every case. Some have different per cost trips for different areas of their city. The Committee pointed out that the highest three cost/trip (Southcenter Parkway S. of 180` Southcenter Blvd 51 t -TIB; and Klickitat Southcenter -I -5 flyover) should be looked at for options that would reduce their high costs. Brent pointed out that one trip could involve several of these areas, each with a separate cost/trip. Reschedule. 3. 2004 Committee Agendas Jim had a list of 11 potential committee agenda items. Some are very large items, such as funding options for infrastructure improvements in the TUC. Almost each of the policies could take several meetings. Staff mentioned that Renton wants a meeting with the Transportation Committee to talk about the Strander project February 9` Information. 4. Relocation of City Light Facilities The Sound Transit (S.T.) project will require undergrounding some Seattle City Light facilities. Staff pointed out those areas where they will not be required to underground, areas where they'll need to raise the wire heights, and areas that will be undergrounded. The area on S. 154 (Southcenter Boulevard) from 42 to TIB is still under discussion, with the City's view that it needs to be undergrounded. Sound Transit wants this agreement to be a separate contract with the City. With only four crews for the whole South end, City Light will lend Sound Transit two of those four crews for this project.
