It is assumed that no public meeting will be required and that the shorelines permit can be issued administratively by the Planning Department. Floodplain Development Permit: A Hydraulic Report will be developed under a different task (Task 7 - River Hydraulics). This report will provide documentation needed to obtain a Floodplain Development Permit from Spokane Valley. The report will address any potential for a rise in river elevation by more than a tenth of a foot during a 100 -year flood event. Deliverables: Prepare and submit a letter to Spokane Valley with the Hydraulic Report attached (report will be attached to the ECS) • Hydraulic Project Approval (HPA) Permit and Section 7 Approval: CH2M HILL will coordinate with the WDFW and track HPA permitting process, including coordination between USFWS and WDFW, the biological evaluation and assessment, and the compensatory mitigation plan. • Water Quality Certification (Section 401) Permit: CH2M HILL will coordinate with Ecology and track Section 401 permitting process, including coordination between USACE and Ecology. • Section 404 Permit: CH2M HILL will coordinate with USACE and track Section 404 permitting process (including wetlands). • DNR Authorization of Entry and Easement: CH2M HILL will coordinate with DNR and track authorization of entry and easement approvals. As required by DNR, CH2M HILL will prepare descriptions of the three guiding principles, an operations plan and a DNR application form, which will all be submitted to DNR to obtain the authorization of entry. An as -built survey of the bridge will be submitted near project completion and additional requirements will be coordinated with the Spokane Valley to obtain the DNR easement. Deliverables: Prepare draft and final DNR application forms for right of entry and for easement, the "Three Guiding Principles" and an operations plan. Assumptions 1. Public involvement with any other stakeholder groups, agencies, organizations or businesses is assumed to be limited to participation in the formal public meetings mandated as part of the permitting process. It is assumed that no public meeting will be required for shorelines permitting, and that the shorelines permit can be issued administratively by the Planning Department. 2. The Local Agency ECS will result in a Documented Categorical Exclusion (DCE) for NEPA and a Determination of Non - significance (DNS) for SEPA. Therefore, there will be SPK/SULLIVAN WEST BRIDGE REPLACEMENT FINAL DESIGN EXHIBIT A -1 SOW.DOCX 4288591D 6OF32 SCOPE OF WORK FOR SULLIVAN ROAD WEST BRIDGE REPLACEMENT, CITY OF SPOKANE VALLEY, JULY 2012 no need for a NEPA Environmental Assessment (EA) or for either a NEPA or SEPA Environmental Impact Statement (EIS). 3. Spokane Valley will provide mapping, transportation data and other information that might be required to complete the ECS and supporting discipline reports, SEPA Environmental Checklist and JARPA. 4. WSDOT will lead consultations with the tribes and other state and federal governmental agencies. If the tribes become involved during the cultural resources field survey or require reimbursement for services, reimbursement of tribal services are not included in this scope of work and will be paid directly by Spokane Valley. 5. Application of Critical Areas Ordinance will be brief. This will include discussions on the aquifer, geological hazardous areas, habitat management, and wetlands. There will not be any need for any special survey, study, analysis, or reports for any of these critical areas. 6. Hydraulic modeling and analysis will be performed under Task 7 — River Hydraulics, which will provide documentation required for a Floodplain Development Permit (addresses potential for rise in river elevation by more than a tenth of a foot during a 100 -year flood event). 7. The Section 4(f) evaluation will not need to address Section 6(f) properties. 8. A de minimis determination for Section 4(f) can be reached and agreed upon by State and Spokane Valley Parks managers for the project. 9. A de minimis determination can be achieved without additional meetings or document preparation, which would be outside of this scope of work. 10. CH2M HILL is not required to prepare documents or attend meetings with Washington State Parks Lands Council to discuss Section 4(f) or right -of -way issues. 11. Compensatory mitigation will be acceptable by fish and wildlife regulatory agencies and no "mitigation site projects" will be assigned to this project or implemented as part of this project. All mitigation fees will be paid by Spokane Valley and is not included in this scope of work. 12. The protection requirements for fish are assumed to be similar to what was required for bull trout at Spokane County's Appleway (State Line) Bridge Replacement project and what was required for red -band trout at the Barker Road Bridge Replacement project. The project scope and budget currently do not include any special evaluations or analyses for fish protection, such as a site - specific noise analysis. 13. Wetlands documentation (inventory, delineation and wetlands mitigation) will be provided by Spokane Valley through a separate agreement with Anderson Environmental. Spokane Valley will coordinate with Anderson Environmental to obtain agency approvals of those documents, which will be attached to the ECS. 14. There are no Bald Eagle nests in the project vicinity. 15. Spokane Regional Transportation Council (SRTC) will conduct the hot spot analysis for the Indiana Avenue and Sullivan Road intersection, and prepare the necessary documentation that will be attached to the ECS. SPK/SULLIVAN WEST BRIDGE REPLACEMENT FINAL DESIGN EXHIBIT A -1 SOW.DOCX 428859.FD 7OF32 SCOPE OF WORK FOR SULLIVAN ROAD WEST BRIDGE REPLACEMENT, CITY OF SPOKANE VALLEY, JULY 2012 16. There is no need to perform a visual impact analysis based on a meeting held with WSDOT on March 12, 2012. 17. There is no need to do a Phase I or Phase II Environmental Site Assessment. 18. Because minority and low- income residences are not anticipated to be found in the project area, a review of the local school- assisted lunch program is not necessary for the environmental justice demographic research. 19. An asbestos survey will be conducted by WSDOT and report findings referenced in the ECS. It is assumed that associated fees would be paid directly by Spokane Valley. 20. The DNR public meeting associated with the DNR right of entry authorization can be conducted prior to issuance of aquatic resource environmental permits from other agencies so that when these bridge permits are issued, the DNR right of entry authorization can be issued immediately by the agency. 21. The Sullivan Road West Bridge Replacement Project will not result in any impacts that are adverse to environmental justice populations and this environmental review will not require a special environmental justice study or evaluation. 22. The schedule assumes Spokane Valley will provide 1 -week reviews for all deliverables. 23. The schedule assumes that WSDOT and FHWA will provide 3 to 4 week reviews for all deliverables. 24. Other permits needed for the bridge replacement project including building, clearing and grading, and public right -of -way are assumed to be the responsibility of Spokane Valley. An NPDES General Permit for Construction is assumed to be the responsibility of the bridge contractor.

Task 9: Final Bridge and Structures Design This task involves final design and contract documentation preparation for replacement of the existing Sullivan Road West Bridge over the Spokane River. Final design will be based on the recommendations in the Preliminary Bridge Design Technical Memorandum, dated March 29, 2012. The following assumptions are made regarding the bridge and structure elements: 1. The existing southbound Sullivan Road West Bridge will be demolished and replaced with a new bridge. 2. The new Sullivan Road West Bridge will be a straight, 4 -span prestressed concrete girder bridge with 4 travel lanes and a pedestrian pathway. The bridge will be approximately 440 feet long, matching the length and skew of the existing Sullivan Road East Bridge. The bridge is anticipated to be supported by multi- column bents founded on drilled shafts. The location of interior piers will match that of the existing Sullivan Road East Bridge. 3. The construction phasing approach to replace the bridge will be based on Construction Phasing Alternative 4, in which the existing northbound Sullivan Road East Bridge will be used to carry three lanes of traffic during construction. 4. The existing Sullivan Road East Bridge (northbound bridge) will be left in place and modified as follows: a) A temporary cantilevered walkway will be added to the east side of the bridge during construction. b) The existing median traffic barrier and pedestrian railing for the bridge will be removed to accommodate three lanes of traffic during construction. A temporary barrier will be placed between the vehicle lanes and the temporary cantilevered SPK/SULLIVAN WEST BRIDGE REPLACEMENT FINAL DESIGN EXHIBIT A -1 SOW.DOCX 428859.FD 16 0F32 SCOPE OF WORK FOR SULLIVAN ROAD WEST BRIDGE REPLACEMENT, CITY OF SPOKANE VALLEY, JULY 2012 walkway at the edge of the bridge deck. Railing will be provided along the east edge of the temporary cantilevered walkway. c) After construction of the new southbound bridge, the temporary barrier and cantilevered walkway and railing will be removed; a new cast -in -place concrete median barrier will be constructed; and the existing pedestrian railing will be reattached to the bridge deck. d) The existing stormwater collection system on the existing bridge will be modified by a separate construction contract designed by Spokane Valley. This construction work is anticipated to occur in spring 2013. Three of the five bridge drains will be plugged at the south end of the bridge. The remaining two drains will be modified to collect stormwater and convey it to a new swale northeast of the existing bridge. e) A temporary stormwater collection system will be required during construction when the existing concrete median barrier is removed. It is assumed that this temporary system will consist of scuppers along the base of the temporary precast barrier and a temporary gutter system along the outside edge of the bridge deck to collect runoff and convey it to the north end of the bridge, where temporary connection will be made to the Spokane Valley - designed pipe system to the new swale. (The temporary cantilevered walkway described in Task 8.7 will be a few inches above the bridge deck to accommodate the temporary gutter system.) 5. The following retaining walls will be required: a) At the south and north ends of the bridge, circular walls at the outlooks, approximately 50- to 60 -feet long. The walls are assumed to be cast -in -place concrete walls with spread footings. b) At the north end of the bridge, a wall along the edge of roadway, approximately 100 -feet long by 6- to 8 -feet maximum height. The wall is assumed to be either cast -in -place concrete with spread footings or a structural earth wall. c) At the north end of the bridge, a wall along the trail, approximately 250 -feet long by 14- to 16 -feet maximum height. The wall is assumed to be either cast -in -place concrete with spread footings or a structural earth wall. d) It is assumed that the walls will have architectural relief to enhance the appearance. e) At the existing northbound bridge, short walls will be required at the ends of the pedestrian walkway on each bank of the river for connection to a new trail. It is assumed that these walls will be cast -in -place concrete with spread footings up to 40 -feet long by 4- to 6 -feet maximum height. 6. All calculations, analyses, design, plans, specifications, and other project work will be prepared in English units. 7. All drawings will be prepared in AutoCAD format in accordance with Spokane Valley drafting standards.
