Description/Abstract: 

Project and construction managers must consider SWPPP compliance when developing work plans, project phasing, and CPM schedules. No longer can construction professionals rely solely on traditional BMPs to keep a project compliant with the CGP. In year's past, developers and builders would never consider SWPPP compliance when planning a project's construction schedule and phasing plan; it is now imperative that the project team prioritize these activities when developing a project's work plan.

Why spend money installing temporary BMPs when you can have the project's landscape contractor install permanent ground cover and plant landscaping? Is it prudent to clear existing vegetation on hundreds of acres, if all that land won't be developed for months to come? Should the builder pave the site early on to minimize the potential for discharges of sediment laden water? All of these (and other) topics should be considered along with their associated costs when planning a project.

Case studies will be used to show how difficult projects can be constructed while remaining in full compliance with current SW permits. For example, Whitson CM's La Costa Condominium project reconstructed over 9 acres of failed slopes over two rain seasons. When developing the CPM schedule for this project, SWPPP compliance was one of our highest priorities. Ignoring the impact of rain would significantly delay the project and costs for temporary BMPs would have a large negative effect on the project's budget. Another example will discuss the staging of Carmel Valley Road. This project was built over 3 rain seasons and several thousand acres drained through the project limits. Only by staging the installations of permanent drainage features was the project able to be successful. Lastly, the presentation will discuss a project where subcontractors were allowed to operate with impunity. They damaged BMPs as soon as they were installed and caused the General Contractor to be cited by both the City and Regional Board. Only after intensive training and removal from the job site of individuals responsible for flagrantly damaging BMPs did the GC get control of the project's compliance activities.

This presentation will address the importance of non-structural BMPs and how they can be used to assure full compliance without incurring large financial impacts.
