THE EROSION & SEDIMENT CONTROL AND STORM. DRAINAGE SYSTEM(S) SHOWN HEREON ARE DESIGNED TO PREVENT THE TRANSPORTATION OF SILT VIA STORMWATER RUNOFF AND TO PROVIDE STORMWATER MANAGEMENT OF THE RUNOFF RESULTING FROM THE IMPROVEMENTS SHOWN. THE DESIGN PONDfiU IS COMPLIANT WITH THE STORMWATER MANAGEMENT MANUAL FOR WESTERN WASHINGTON - 2012 (SWMMWW). 2. UNLESS SPECIFIED OTHERWISE ON THESE PLANS OR BY COUNTY CODE, ALL MATERIALS AND WORKMANSHIP SHALL CONFORM TO THE MOST RECENT ADOPTED EDITIONS OF: • THE INTERNATIONAL BUILDING CODE / INTERNATIONAL RESIDENTIAL CODE (IBC/IRC), AS AMENDED BY WASHINGTON STATE; • STANDARD SPECIFICATIONS FOR ROAD, BRA, AND MUNICIPAL CONSTRUCTION, WASHINGTON STATE DEPARTMENT OF TRANSPORTATION (WOOT-5S); • AMERICAN PUBLIC WORKS ASSOCIATION (APWA), WASHINGTON CHAPTER, 3. THESE PLANS AND ASSOCIATED REPORT(S), AS APPROVED BY CLALLAM COUNTY, DO NOT RELIEVE A BUILDER OR OWNER FROM COMPLYING WITH ADDITIONAL OR FUTURE REGULATORY REQUIREMENTS.

IMPROVEMENTS SHALL BE LOCATED SO THEY DO NOT ENCROACH ON SEPTIC SYSTEM COMPONENTS OR RESERVE AREA(S), EASEMENTS, STRUCTURES, OR BUFFERS. REQUIRED SEPARATIONS INCLUDE: • 100' BETWEEN WELLS AND SANITARY DRAINFIELD & RESERVE AREAS • 2' BETWEEN BUILDING AND CONVEYANCE SYSTEMS • 10' BETWEEN BUILDING AND DRYWELL • 30' BETWEEN SANITARY DRAINFIELD AND DRYWELL(S). 5. CONSTRUCTION SEQUENCE SHALL BE AS FOLLOWS: A. PROMINENTLY FLAG BUFFERS AND CONSTRUCTION LIMITS. B. LOCATE EXISTING UTILITIES, VERIFY ELEVATIONS AND GRADES C. PLACE GRAVEL SURFACING ON EXISTING DRIVE D. INSTALL TEMPORARY EROSION CONTROL MEASURES REQUIRED BY SITE CONDITIONS E. ROUGH GRADE SITE F. INSTALL DRAINAGE SYSTEM (DO NOT CONNECT FOUNDATION AND STORMWATER DRAINS) G. CONSTRUCT ON -SITE SEWAGE AND WATER SYSTEMS AS APPLICABLE H. CONSTRUCT BUILDING FOUNDATION I, CONSTRUCT BUILDING J. FINE GRADE DISTURBED AREAS K. PERMANENT SEED OR ESTABLISH OTHER APPROVED PERMANENT GROUND COVER. L FOLLOWING STABILIZATION OF SITE AND THE DEVELOPMENT OF PERMANENT GROUND COVER REMOVE TEMPORARY EROSION CONTROL MEASURES AND ACCUMULATED SEDIMENT. 6. TOPOGRAPHIC INFORMATION SHOWN IS PER JEFFERSON COUNTY AND/OR OTHER PUBLIC RECORDS. THE FEATURES SHOWN AS EXISTING ARE SHOWN IN THEIR APPROXIMATE AND / OR REPORTED LOCATION. THE OWNER SHALL BE RESPONSIBLE TO HAVE ANY SURVEY COMPLETED THAT MAY BE NECESSARY AS A RESULT OF THESE PLANS. 7. AVOID CONSTRUCTION DURING FALL AND WINTER OR OTHER PERIODS LIKELY TO EXPERIENCE HEAVY RAINFALL. DURING HEAVY RAIN, PLACE VISQUEEN SHEETING, SOIL BLANKETS, OR EQUIVALENT PROTECTION OVER AREAS WITH EXPOSED SOIL B. DISTURBED AREA THAT HAS BEEN STRIPPED OF VEGETATION AND WHERE NO FURTHER WORK IS ANTICIPATED FOR A PERIOD OF 2 DAYS BETWEEN OCTOBER 1ST THROUGH APRIL 30TH (WET SEASON) OR 7 DAYS BETWEEN MAY 1ST THROUGH SEPTEMBER 30TH (DRY SEASON), MUST BE IMMEDIATELY STABILIZED WITH COMPOST. MULCHING, GRASS PLANTING, OR OTHER APPROVED EROSION CONTROL TREATMENT APPLICABLE TO THE TIME OF YEAR. SEEDING ALONE IS ONLY ACCEPTABLE BETWEEN THE MONTHS OF APRIL THROUGH SEPTEMBER INCLUSIVE, SEEDING MAY PROCEED OUTSIDE THE SPECIFIED TIME PERIOD WHENEVER IT IS IN THE INTEREST OF THE DEVELOPER, BUT MUST BE AUGMENTED WITH MULCHING, NETTING, SOD, PLASTIC COVERING, OR OTHER TREATMENT. 9. SEEDING SHALL BE WITH KENTUCKY BLUE GRASS, TALL FESCUE, PERENNIAL RYE, OR CHEWING FESCUE. THE APPLICATION RATE SHALL BE 12D POUNDS OF SEED PER ACRE. ALL WORK SHALL BE COMPLETED CONSISTENT WITH BMP C120: TEMPORARY AND PERMANENT SEEDING IN VOLUME II STORMWATER MANAGEMENT MANUAL FOR WESTERN WASHINGTON - 2012. 10.
