In order to be included in the RAP priority array, this prospectus must be submitted to CRAB via an online database and signed hard copies sent by September 1. Analysis/Strategic Goals/Pros Et Cons: The segment of South Discovery Road 3 R project (Resurfacing, Restoration and Rehabilitation) between MP 4.52 and MP 4.84 has narrow 11 foot lanes and 3 foot wide gravel shoulders. This project proposes to overlay the existing lanes and widen the 3 foot gravel shoulders to 5 foot paved shoulders. These measures will preserve the existing pavement while increasing overall safety with wider shoulders. Fiscal Impact/Cost Benefit Analysis: Our local funds available for road construction are limited. The Rural Arterial Program is one outside source available to counties. If projects are selected, RAP funds cover 90% of the project cost and the local match is 10%. This is a competitive program within the RAP Northwest Region and no funds are guaranteed for any county. Preliminary planning estimates indicate the total cost of the project is $920,000. If selected, RAP could fund $828,000. County match from the local road fund would be $92,000. This RAP project is included in the draft Six -Year Transportation Improvement Program (TIP) for 2017-2022.

Discovery Rd. is narrow with 11 foot wide travel lanes and 3 foot wide gravel shoulders. The narrow shoulders within this segment are heavily utilized by the adjacent property owners which include a general contractor with numerous accesses for their offices, equipment yard, shop buildings and staging areas; an auto wrecking yard and metal recycling facility; a UPS distribution center; a mini storage complex; and a few residences. The existing gravel shoulder also serves as a non -motorized link from the Milo Curry Road terminus of the Larry Scott Trail (a portion of the Olympic Discovery Trail) and the newly completed Jefferson Transit Authority Facility (located at Four Corners Rd. and SR -20). The commercial / industrial uses generate a number of large truck traffic trips, whereas the residences, trail and transit facility introduce many non -motorized users to this rural segment of road. The proposed project will provide an important safety improvement for the wide variety of users of this segment by widening and paving the shoulders to 5 feet which will require the removal and/or relocation of numerous roadside hazards. Deviation Anticipated? Roadway Structural Section, or Bridge Condition: his project will overlay the existing pavement and widen the existing 3 foot gravel shoulders to 5 foot paved shoulders. Horizontal Alignment: o changes in horizontal alignment are planned. Vertical Alignment: o changes in vertical alignment are planned.

In keeping with these guidelines, I have considered the following factors as well as others in arriving at the proposed scope of improvements: Roadside conditions Funding constraints Environmental concerns Changing traffic and land use patterns Deterioration rate of surfacing Accidents or accident rates. Where justified, the project will include: Guardrail improvements or upgrades Approach and and transition guardrail improvements for bridges Beveled end sections for crossing and parallel culverts located in the clear zone. Relocating, protecting, or providing breakaway features for sign supports and luminaires Protection for exposed bridge piers and abuttments. Removing fixed objects from the clear zone Improvements to roadway geometry. With these and other improvements as mentioned in the project prospectus, the project will sufficiently extend service life, provide additonal pavement strength, restore or improve the original cross section, and enhance safety.
