EXHIBIT A SCOPE For ENGINEERING SERVICES In 2009 Taylor Engineering completed design plans and specifications for the milling and overlay of Sprague Avenue between Evergreen and Sullivan Roads. The plans included construction signing, storm drainage improvements, limited removable and replacement of pavement with unsuitable subgrade, ADA access improvements, restriping, new traffic loops at the intersections of Adam and Progress Roads, and interconnect conduit for traffic control. At that time, the plan was to mill and overlay 2 inches of asphalt pavement, similar to Sprague Avenue west of Evergreen Road, completed recently. Now in November, 2011, the City of Spokane Valley believes a more complete renovation of the pavement and subgrade is warranted. Taylor Engineering has reviewed the previous plans and concludes that the plans and specifications may be revised and updated to provide construction documents for the new project. This work will be completed for bidding prior to March 19, 2012. SCOPE 1 —Administration A.

Agents with the Spokane Valley have secured the funding to resurface sections of Sprague Avenue. As a function of this project, the City staff is looking to update hardware/ materials for the Sprague Avenue /Adams Street traffic signal and deactivate the Sprague Avenue /Progress Road signal (removing some hardware), as the signal is no longer needed /warranted to control traffic volumes at this time. Thus, this project includes the provision of designs to update the Sprague Avenue /Adams Road traffic signal with updated hardware /materials, as this signal will be installed with the resurfacing project. Plans for the Sprague Avenue /Progress Road signal have not yet been finalized. At a minimum, the City may simply shut off the signal and leave all hardware, poles, and signal heads in place. On the more assertive end, the City may wish to pull the majority of hardware (potentially removing signal heads) and prepare the intersection for updated signal construction again in the future, when warrants based on prevailing traffic conditions. Our scope and budget proposal includes the provision of designs and material recommendations to update the Sprague Avenue /Progress Road signal, such as locating conduits and signal control boxes, to provide a conservative estimate of work. However, work and budget could be reduced accordingly if the City decided no designs are required following project initiation. Taylor Engineering will lead this project and provide designs for the resurfacing project. ITS, LLC traffic engineering services have been requested to assist with redesign plans for both signals. In addition, ITS LLC staff will provide: demolition plans current signals, assist with traffic control plans, attend project, meetings, attend a public meeting, and assist with specs, bid /quantities, and construction advertising. The traffic engineering elements required to perform these actions items is summarized as follows: ♦ Meetings. Meet with City of Spokane staff for a scoping session, and to review initial and final design plans. These meetings are performed to identify comments and steps required to prepare 100 percent /final design plans for the project in accordance with current City, County, and State practices. One additional meeting will be used to address other elements such as the demo plan, bid quantities, etc. This represents a total of four programmed/ formal meetings for this project. ♦ Public Meeting. The project will impact access to businesses and homes located along Sprague Avenue. As such, City staff wishes to perform a public meeting to inform the public of the project, proposed traffic control conditions, and to solicit comments. Staff from ITS LLC has been requested by the project manager to attend and support this meeting. ♦ Traffic Control Plans. We will work with Taylor Engineers to develop traffic control plans the Sprague avenue corridor, as well as any special provisions are analysis for the Progress and Adams intersections with Sprague Avenue, as needed. These plans will provide schedule estimates for constniction, as well as the routing recommendations needed to facilitate the safe and effective movement of traffic wile construction and demolition occurs at the intersection. Plans will be prepared primarily in accordance with the 2012 WSDOT Specifications Manual; again, as supported with any operational /traffic analyses that may be required for rush hour conditions. Note there may need to be some phasing of control plans, pending the outcomes of public Page 1 ITS Intermountain Transportation Solutions Traffic Studies ♦ Transportation Analysis ♦ Signal Design ♦ Site Planning meetings and construction schedules. Ourinformation will be provided to Taylor Engineers electronically (in AutoCad) for production and incorporation into master plan sets. ♦ Demo Plan and Material Review. We will work with Taylor engineers to provide demo plans for the study intersections. The materials removed will be reviewed to determine whether any components can be utilized for use in future signals. Coordination will ensue with City staff to determine what materials should remain for the Progress Road /Sprague Avenue intersection. Our information will be provided to Taylor Engin eers electronically (in Auto Cad) for production and incorporation into master plan sets. ♦ Designs Plans. ITS staff will develop initial and final /100 - percent designs for the Sprague Avenue /Adams Road and Sprague Avenue /Progress Road traffic signals. As indicated, full designs will be prepared for the Sprague Avenue /Adams Road intersection, as this signal will be updated and constructed with the intent for immediate operation. We have assumed that design plans for Sprague Avenue /Progress Road will be needed for the purpose of this project scope, and will include the location of conduits, signal control boxes, and signal poles (these designs can be reduced if the City elects not to move forward on Progress improvements). The intent is to develop the intersection for future signalization, as needed based upon prevailing traffic volumes. These plans sheets will contain details such as the location and type of signal poles, mast arms, pull/controller boxes, conduits, preemptive devices, circuits, power connection, etc. and plans required for the operation of a traffic signal. Special elements of design include coordination with The Transpo Group regarding an intelligent transportation system project for Sprague avenue and coordination with City staff regarding the location of proposed bus stops. Designs will be provided per City requirements and will include general information, signal details, phasing plans, wiring /electrical details, and any special provisions. We estimate signal design information will be provided on three plan sheets, which will be submitted electronically (In AutoCad) to Taylor Engineering for review and production with master plan sheets. Special notes and instructions provided by City staff this far for the project are as follows: Sprague /Adams — Purchase new poles and arms for the N\V and SE corners of the intersection, — Replace cabinet foundation and purchase new cabinet, — Replace all wiring underground, — Upgrade any small concrete junction boxes, — Install T -cans on all 4 poles, Replace electrical service on the NE corner (pole- mounted) with new pole- mounted service. — Install countdown pedestrian heads and new pushbuttons at the intersection, — Add advance detection on Sprague, Extend the overlay to the north and south approaches and replace the stop bar detection, and Provide bicycle loop detection on Sprague Avenue (and Possibly Adams pending future coordination with City staff). Sprague/Progress — The decision to leave signal heads up or remove will be made at the onset of the project (will provide designs in accordance), — Replace the detection either way, Page 2 ITS Intermountain Transportation Solutions Traffic Studies ♦ Transportation Analysis ♦ Signal Design ♦ Site Planning — Extend the overlay to the south approach and replace the stop bar detection, — Detection on the north leg was recently replaced, so protect these loops, — Designs should show updated pedestrian heads and pushbuttons, — Designs should show replaced wiring (splices in the jboxes), new cabinet and foundation location, and installation of T -cans and upgrade the electrical service, — Designs should show bicycle loop detection on Sprague Avenue (and Possibly Progress pending future coordination with City staff). ♦ Bid Quantities. ITS will work with Taylor Engineering to develop bid quantities for use in the project contracting /construction process. We will help project the cost of all materials, construction impacts (project development, traffic plan contracting, etc.) as well as estimate the reasonable mark -up expected for actual construction efforts. Support information will be submitted electronically (in Excel or Word) to Taylor Engineering for review and submittal to the City with master quantity work. ♦ Specifications Review and Final. We will work with Taylor Engineering and City staff to prepare signal specifications for the Adams Road /Sprague Avenue traffic signal and the Sprague Avenue /Progress Road future signal, as needed. These specifications will include materials information, electrical details, signal operation information /data, etc., as per City and /or State code (per the 2012 WSDOT Specifications Manual). Designs, specifications, control plans, and bid quantities will be finalized for use by the City in bidding and construction the project. Our information wig be provided to Taylor Engineers electronically (in AutoCad and Word) for production andincorporation into masters and documentation.
