Project Schedule

A proposed project schedule is shown in Table 1. Todd Groundwater can begin this project
upon receipt of a notice‐to‐proceed and anticipates that the project can be completed within a
20‐week (4.5‐month) timeframe assuming immediate initiation of the project, timely scheduling
of the pre‐construction meeting and identification of water sources, confirmation of site
management requirements by SBCFCD and other regulatory permitting agencies, and receipt of
comments by Valley District and partner agencies on the Draft Report.

We anticipate Task 1 (Pre‐Field Planning) will take approximately 2 weeks to complete.
The implementation of the infiltration tests is based on the recommended approach described
in Section 3.1 (Fieldwork Schedule) of the Work Plan. Such an approach involves performing
initial site preparation and test initiation at two sites, staggered one week apart. Site
demobilization, preparation, and test initiation would occur on Mondays of each week. Under
this scenario, site preparation and test initiation at Site 1 would occur on Monday of the first
week (Week 1). This would be followed by site preparation and test initiation at Site 2 in Week
2. At the beginning of Week 3, testing would be completed at Site 1, and equipment and
materials would be moved from Site 1 to Site 3, where testing would begin the same week. At
the beginning of Week 4, testing would be completed at Site 2, and equipment and materials
from Site 2 would be moved to Site 4, where testing would begin the same week. This process
would be repeated a‐needed to complete infiltration testing at the thirteen sites. Given this
staggered approach, the number of weeks to complete proposed infiltration testing is equal to
the number of investigation sites plus one week (or 14 weeks).

The proposed field schedule provides the following advantages: (1) the contractor is on a fixed
weekly schedule for excavation, equipment mobilization/demobilization and monitoring
activities, and (2) materials and labor (including fire hose, manifolds, basin trees, fencing, and
traffic ramps/signage) are required for exactly two sites for the project at any given time.

The draft report would be prepared and submitted to Valley District within 2 weeks of the
completion of final testing. The final report would be prepared and submitted one week after
receipt of all agency comments.
