CONDITIONS
Provisions for surface/subsurface drainage control must be implemented with new construction or development on site and
MUST NOT adversely impact adjacent parcels. Under the requirements of Mason County Stormwater Ordinance, either
private ditches and drains will meet requirements of the stormwater ordinance or prior approval will be granted to use an
existing utility and drainage easement dedicated for that specific purpose. For further information regarding this ordinance
and the REQUIREMENT to obtain an ACCESS PERMIT for the installation/construction of a driveway or access connecting
from a Mason County Road, Contact the Mason County Public Works Department prior to construction at Ext 450. For any
construction which is proposed to be located within 25' of a Mason County road right of way, it is suggested to contact that
office to review future planned work which may affect your project.
• All property lines shall be clearly identified at the time of foundation inspection.
* When parcel development requires direct access to county road(s), a Road Access Permit or Approval must be granted by
the Mason County Department of Public Works. For more information contact Public Works, at (360)427-9670, ext. 450 or
100 W Public Works Dr. Shelton. The building permit will not be finaled until the permit holder can show proof that the
access permit from Public Works has been finaled and approved.
CONSTRUCTION PROCESS TO BE FIELD CORRECTED AS REQUIRED PER MASON COUNTY BUILDING
DEPARTMENT AND THE ADOPTED BUILDING CODE.
The construction of the permitted project is subject to inspections by the Mason County Building Department. All

* Approved per dimensions and setbacks on submitted site plan. Setbacks are measured from the furthest projection of the
structure.
* All changes to"approved" building plans that effect compliance with the international codes as amended and adopted, or
any other Mason County ordinance or regulation, must be reviewed and approved by Mason County prior to construction.
* The plan review check list and corrections are part of the approved plans and must remain attached. It is the responsibility
of the applicant, owner or contractor to make the required corrections indicated on the plans. Once the plans are marked
"APPROVED", they shall not be changed or altered without authorization from the Building Official. The permit holder is
