CONSTRUCTION IS COMPLETED AND POTENTIAL FOR ON-SITE EROSION HAS PASSED. THE
IMPLEMENTATION, MAINTENANCE, REPLACEMENT AND ADDITIONS TO EROSION/SEDIMENTATION CONTROL
SYSTEM SHALL BE THE RESPONSIBILITY OF THE PERMITEE.
4.THE EROSION AND SEDIMENTATION CONTROL SYSTEMS DEPICTED ON THIS DRAWING ARE INTENDED TO
BE MINIMUM REQUIREMENTS TO MEET ANTICIPATED SITE CONDITIONS. AS CONSTRUCTION PROGRESSES
AND UNEXPECTED OR SEASONAL CONDITIONS DICTATE, THE PERMITEE SHALL ANTICIPATE THAT MORE
EROSION AND SEDIMENTATION CONTROL FACILITIES WILL BE NECESSARY TO ENSURE COMPLETE

APPLICABLE TO THE TIME OF YEAR. BRASS SEEDING ALONE WILL BE ACCEPTABLE ONLY DURING THE
MONTHS OF APRIL THROUGH SEPTEMBER, INCLUSIVE. SEEDING MAY PROCEED, HOWEVER, WHENEVER IT
IS IN THE INTEREST OF THE PERMITEE, BUT MUST BE AUGMENTED WITH MULCHING, NETTING OR OTHER
TREATMENT APPROVED BY THE CITY OF RENTON, OUTSIDE THE SPECIFIED TIME PERIOD.
8.FOR ALL EROSION/SEDIMENTATIN CONTROL PONDS WHERE THE DEAD STORAGE DEPTH EXCEEDS 6
INCHES, A FENCE IS REQUIRED WITH A MINIMUM HEIGHT OF THREE (3) FEET, 3:1 SIDE SLOPE.

GENERAL NOTES TAKEN FROM SURVEY
1.) BOUNDARY LINES SHOWN ARE BASED ON RENTON SHORT PLAT #LUA-08-137-SHPL
RECORDED IN VOLUME 268 OF SURVEYS, PAGES 168-170, IN KING COUNTY, WASHINGTON.
2.) INSTRUMENTATION FOR THIS SURVEY WAS A TRIMBLE VX SPATIAL STATION.
PROCEDURES USED IN THIS SURVEY WERE FIELD TRAVERSE, MEETING OR EXCEEDING
STANDARDS SET BY WAC 332-130-090.
3.) THE INFORMATION DEPICTED ON THIS MAP REPRESENTS THE RESULTS OF A SURVEY
MADE IN MAY 2017 AND CAN ONLY BE CONSIDERED AS INDICATING THE GENERAL CONDITION
EXISTING AT THAT TIME.
4.) SANITARY SEWER AND STORM DRAINAGE FACILITIES HAVE BEEN ASBUILT THROUGH
FIELD MEASUREMENTS OF THE LOCATION OF THE ACCESS STRUCTURES, THE TOP
ELEVATION OF THE STRUCTURES, AND THE INVERT ELEVATIONS OF ANY PIPES ENTERING OR
LEAVING THE STRUCTURES. IT IS STANDARD PRACTICE TO SHOW THE PIPES CONNECTING
THESE STRUCTURES AS STRAIGHT LINES. THIS IS ONLY AN ASSUMPTION AND THE ACTUAL
LOCATION OF THE PIPING MUST BE VERIFIED IN THE FIELD BY THE CONTRACTOR PRIOR TO
ANY CONSTRUCTION.
5.) NO EASEMENTS, RESTRICTIONS OR RESERVATION OF RECORD WHICH WOULD BE
DISCLOSED BY TITLE REPORT ARE SHOWN.
6.) PIPE ELEVATIONS SHOWN FOR INACCESSIBLE YARD DRAIN STRUCTURES ARE
APPROXIMATE TO THE TENTH OF A FOOT AND SHOULD BE FIELD VERIFIED PRIOR TO ANY
CONSTRUCTION ACTIVITY AS NECESSARY.
