1. Earth:
a. General description of the site (circle one): r a , rolling, hilly, steep slopes,
mountainous. other-
b. What is the steepest slope on the site (approximate percent slope)?
The site is basically flat. A landscaped berm surrounds and separates
the office buildings from the parking lots. The berms are sloped at 13%,
average.
C. What general types of soils are found on the site (for example, clay, sand,
gravel, peat, muck)? If you know the classification of agricultural soils,
specify them and note any prime farmland.
Unknown.
d. Are there surface indications or history of unstable soils in the immediate
vicinity? If so, describe.
The existing office buildings' foundations consist of friction type timber
piles and a structural concrete slab, which indicates that native surface
soils were inadequate to .support the structures. More than, this is not
known at this time.
e. Describe the purpose, type, and approximate quantities of an fillip or
grading proposed, indicate source of fill. y g
The purpose of the proposed filling in Phases / and // is to construct level
play areas adjacent to new classrooms inside the existing building. Fill
will consist of on -site excavated materials where possible and imported
structural fill from approved quarry source as supplement.
Phase 1 quantity of proposed excavation is 20.59 cubic yards. Quantities
of proposed fill are 20.59 cubic yards of native material and 258.41 cubic
yards of imported fill for a total of 279 cubic yards. There will be 0 cubic
yards of native material to be disposed of.
Phase lI quantity of proposed excavation is 14.9 cubic yards. Quantities
of proposed fill are 14.9 cubic yards of native material and 320.1 cubic
yards of imported fill for a total of 335 cubic yards. Therz will be 0 cubic
yards cf native material to be disposed of.
Could erosion occur as a result of clearing, construction, or use? If so,
generally describe.
