PHASE I CONTROL MEASURES, WHICH ARE NOT IN CONFLICT WITH FINAL CONSTRUCTION AND PROVIDE EFFECTIVE CONTROL, SHALL REMAIN IN PLACE FOR FINAL DEVELOPMENT. THE CONTRACTOR SHALL FOLLOW THE COUNTY ENGINEERING DEPARTMENT'S DIRECTION IN PROVIDING ADDITIONAL CONTROL MEASURES NEEDED DURING THE DEVELOPMENT PROCESS, TO ENSURE THAT SEDIMENT IS PREVENTED FROM POLLUTING OFF-SITE AREAS, STREAMS AND/OR PROTECTED ON-SITE AREAS. THE FOLLOWING SEQUENCE OF

CONSTRUCTION IS SUGGESTED.

1. ROUGH GRADE THE SITE INCLUDING ROADWAYS, DRIVE AISLES, PARKING AREAS, AND SWALES.

2. BEGIN CONSTRUCTION OF BURIAL SECTIONS AND STRUCTURES.

3. THROUGHOUT CONSTRUCTION, INITIATE TEMPORARY OR PERMANENT STABILIZATION MEASURES IMMEDIATELY FOLLOWING THE

COMPLETION OF THE MOST RECENT LAND DISTURBING ACTIVITY. DISTURBED AREAS SHALL BE SEEDED AND MULCHED IF THEY

ARE TO REMAIN UNDISTURBED FOR 14 DAYS OR LONGER.

4. INSTALL UNDERGROUND UTILITIES, INCLUDING STORM SEWER, SANITARY SEWER AND WATER LINES.

5. INSTALL INLET PROTECTION AT ALL STORM DRAIN INLETS AS EACH STRUCTURE IS INSTALLED.

6. INSTALL RIP RAP-END SECTION AT EACH OUTLET STRUCTURE AS EACH STRUCTURE IS INSTALLED.

7. CONSTRUCT THE BASE PAVEMENT FOR ROADWAYS, DRIVE AISLES, AND PARKING AREAS, AND INSTALL CURB SECTIONS.

8. INSTALL ADDITIONAL EROSION AND SEDIMENT CONTROL MEASURES AS NEEDED THROUGHOUT CONSTRUCTION.

9. FINAL GRADE ALL AREAS OF THE SITE LEAVING SEDIMENT CONTROLS IN PLACE AS NEEDED. SPREAD TOPSOIL OVER AREAS TO BE

SEEDED.
