Pursuant to your request, Petra Geotechnical, Ina (Petra) has observed and
performed relative compaction tests of the compacted subgrade on Martha's
Vineyard Lane, Spring Place Court, Baz Hazbor Lane and Cape Cod Lane within
Tract 32170 (Harveston Neighborhood 6), located in the City of Temecula,

The finished subgrade was tested on February 21 and 22, 2006. Results indicate
that relative compaction of samples tested were in excess of 95 percent as
determined by the sandcone method (ASTM D1556). Based on the results of our
tests and observations, it is our opinion that the subgrade soils within the subject
