This checklist was prepared and transmitted to your office with a Determination of Nonsignificance on April 20`h for publication in the SEPA Register. This addendum revises item A.I I (description of project). After the initial preparation of the checklist, two additional items of work were identified as a part of this project. A description of these additional items are included in the revisions to item A.11. Consideration of the environmental impacts of the additional items of work does not change the threshold determination for this proposal. If you have any questions or need further information, please contact Lynn Hakes at (360) 357-2674 or Tom Whitney (360) at 357-2749. Sincerely, Kenneth M. Stone Region Environmental Manager Olympic Region KMS:Ish Attachment cc: Mason County Neal Campbell file ADDENDUM TO ENVIRONMENTAL CHECKLIST Name of proposed project: SR 3 Allyn Vicinity Slide Repair Name of applicant: Washington State Department of Transportation Olympic Region Address and phone number of applicant and contact person: Kenneth M. Stone Olympic Region Environmental Manager PO Box 47440 Olympia, WA. 98504-7440 Telephone:(360) 357-2660 Date checklist prepared: April 20, 1999 This Addendum revises item A.11 of the SEPA Checklist prepared for this project. Two additional items of work have been identified as a part of this project. They are noted in italics and underlined in item 11 (description of project) as set forth below. 11. Give brief, complete description of the project including (but not limited to) its size, general design elements, and other factors that will give an accurate understanding of its scope and nature. There are several questions in this checklist that ask you to describe certain aspects of the proposal. You do not need to repeat those answers on this page. The purpose of the project is to repair SR 3 following a recent slide that caused significant damage to the site. The roadway will be reconstructed to the previous horizontal and vertical alignments. Drainage facilities will be constructed to convey stormwater under the roadway. A retaining wall will be constructed on the east side of the roadway to prevent future slides from occurring. A trench drain will be installed on the west side of the roadway to decrease the subsurface water pressure upon the retaining wall. A series of horizontal drains will be installed into the hillside to the west o_f SR 3 within the area of slope instability to remove the excess water. There will be repairs done to North Bay Road, a portion of the slide detour. This portion is 1.9 miles long. Sections of this roadway are within 200 feet of a shoreline. A 1.26 mile section of the Victor Cutoff Road, a portion of SR 302 which is being used as a detour route, will be preleveled to a depth of 20 mm, and will receive pavement overlay of 45 MM. 1 Washington State Olympic Region Headquarters Department of Transportation 5720 Capitol Boulevard,Tumwater Sid Morrison P.O.Box 47440 Olympia,WA 98504-7440 Secretary of Transportation (360)357-2600 Fax(360)357-2601 April 22, 1999 PFDElVED Mr. Allan Borden APR 2 6 1999 Mason County Department of Community Development MASON CO.PLANNING DEPT P.O. Box 578 Shelton, WA 98584-0578 SR 3, DMC-001 MP 22.51 to MP 22.73 Allyn Vicinity Slide Repair Shoreline Exemption and Critical Area Review Dear Mr. Borden: Attached please find a copy of an addendum to the SEPA Checklist for the above referenced project. After the initial preparation of the checklist, two additional items of work were identified as a part of this project. A description of these additional items are included in the revisions to item A.I I (project description). Our JARPA form submitted to your office on April 20, 1999 also omitted these project components. The installation of the horizontal drains will need to be considered in your review under the Mason County Critical Areas Ordinance regarding geologically hazardous areas and wetland buffers. In addition to the pavement repairs to North Bay Road which occur within 200 feet of North Bay, it appears that the pavement overlay of the Victor Cutoff Road (a portion of SR 302)may end within 200 feet of the confluence of Coulter Creek and North Bay, and may need to be considered in our application for exemption from Shoreline Substantial Development Permit.

I understand that the application for Shoreline Exemption and Mason Environmental Permit arrived without the fee attached.
