RE: La Costa Glen Archaeological Mitigation Program
Dear Mr. Westman:
Since early March, we have been conducting the data recovery program at Site SDI-13,172 at
the La Costa Glen Project in Green Valley. The program has followed the outline provided to you in the
Research Design document submitted in February. In accordance with our plan, we began the project
with a 5% sample of 13 test units in the location designed by Archaeological Associates as the area of
significance of the prehistoric occupation at SDI-13,172 (Archaeological Associates 1993). The test
units were excavated to depths that equaled or exceeded the reported depth of the archaeological
deposit identified by Archaeological Associates.
The results of the excavation of the 13 test units generally correlated with the results of the
units excavated previously in 1993. The recovery from the units typically included a less than 15 flakes
and 10 marine shell fragments. The total recovery from the test units included 72 pieces of lithic
production waste (primarily flakes), two manos, one projectile point fragment, and one potsherd of
Tizon Brown Ware. Marine shell from the units included approximately 91.3 grams, and 11.8 grams of
food bone was also recovered. The projected discovery of features or concentrations of artifacts, as
proposed by Archaeological Associates, never materialized. The overall recovery from the test units
was disappointing, as the research potential of the materials from the test units is very limited.
Based upon the recovery from the test units, the potential to find any significant components
within the boundaries of SDI-13,172 seems very remote. Since the deposit appears to be very
homogeneous, and lacks any indications of features, I will propose that the Phase 1 sample of 5% will
be sufficient to achieve the goals of the data recovery program. A Phase 2 sample will not be required,
and no additional field work is necessary. We will contin~ie to conduct the laboratorv analysis, and
will submit a final technical report in the next month. At this tune, the property can be released for
grading from the standpoint of the cultural resource mitigation requirements of the EIR and conditions
of approval. I would recommend that an archaeologist be on site during the grading operation in the
area of SDI-13,172 in the event that other important deposits are uncovered and require salvage.
If you have my questions regarding the data recovery program, please call me.
