THESE NOTES SHALL APPEAR FOR PROJECTS — SITE IMPROVEMENTS, SURFACE q;t WATER UTILITY, WASTEWATER UTILITY, WATER UTILITY, AND TRANSPORTATION PLANS: L0 2. BEFORE ANY CONSTRUCTION OR DEVELOPMENT ACTIVITY OCCURS, A O PRE—CONSTRUCTION MEETING MUST BE HELD WITH THE CITY OF RENTON, C) PUBLIC WORKS DESIGN ENGINEER. qt 3. THE BOUNDARIES OF THE CLEARING LIMITS AND AREAS OF VEGETATION PRESERVATION r AS PRESCRIBED ON THE PLAN(S) SHALL BE CLEARLY FLAGGED BY SURVEY TAPE OR FENCING IN THE FIELD PRIOR TO CONSTRUCTION IN ACCORDANCE WITH APPENDIX "D" OF THE SURFACE WATER DESIGN MANUAL AND OBSERVED DURING CONSTRUCTION.
