RE: Plan Check # 2006-0996
Project: Pritchett Pool/Spa
Project Address: 18108 76t' Ave W.
During review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please redline plans or submit two (2) sets of revised
plans/documents (affected sheets only) with a written response to each of the items below to a
Permit Coordinator.
Before all Building Plan Review items below are addressed you may want to review and consider
comments from the Planning and Engineering Departments (to follow shortly) before deciding
how to proceed with this application.
1) Please submit a complete soils report just for area of the proposed poollspa complying with IRC
chapter 4 with specific design criteria for proposed swimming pool/spa. See attached for
minimum report submittal requirements. All design criteria specified by the Geotech of Record
must be incorporated in the pool design by the Structural Engineer of Record.
2) For proposed pool fence specify that there shall be no opening greater than 2". Also how will
protection along the North side of the house be obtained (i.e. self closing, self latching gate?).
Currently as shown someone could walk along the North side of the house and gain access to the
pool.
3) Energy code requires all heated pools to have a pool cover. Note on plans.

SOILS INVESTIGATION AND/OR REPORT (Cont.)
The classification of bearing soil at the site must be
determined and called out on the plans. The following
information from IRC Table R401.4.1, will assist
individuals in determining the soil classification of the
building site. The Building Official may require this
classification to be made by a Washington State licensed
Geotechnical Engineer or Engineering Geologist in a
written report when soils are not adaptable to conventional
spread footings or if allowable foundation and lateral
pressures do not meet the values set forth in the table
below. The allowable foundation and lateral pressures
may not exceed the values in this table, unless data to
substantiate the use of higher values is submitted. Sidehill
or steep slope construction IS NOT considered
conventional construction and soils reports are required for
lots with 15% or more slope, unless determined
unnecessary by the Building Official. For more specific
and technical information on soil capacity, foundation
design and construction components, refer to IBC Chapter
18 and 1RC Chapter 4 or contact a professional engineer_

For SI: 1 pound per square foot = 0.0479 kN/m2.
a. When soil tests are required by Section R401.4, the allowable bearing
capacities of the soil shall be part of the recommendations.
b. Where the building official determines that in-place soils with an
allowable bearing capacity of less than 1,500 psf are likely to be present
at the site, the allowable bearing capacity shall be determined by a soils
investigation.
hen soils reports are required, they shall include the following:
1. A plot plan showing the location of test borings and/or excavations.
2. A complete record of the soil samples.
3. A record of the soils profile.
4. Elevation of the water table, if encountered.
5. Recommendations for foundation type and design criteria, including but not limited to: bearing capaci
of natural or compacted soil; provisions to mitigate the effects of expansive soils; mitigation of the effe I s
of liquefaction, differential settlement an carrying soil strength, the effects of adjacent loads, and
foundation drainage.
b. Expected total and differential settlement.
7. Pile and pier foundation information in accordance with IBC Section 1808.2.2.
8. Special design and construction provisions for footings or foundations founded on expansive soils, as
necessary.
9. Compacted fill material properties and testing in accordance with IBC Section 1803.5.
NOTE: Report recommendations shall be incorporated into the foundation design
4. DRAINAGE PLAN (See Handout #E72) r�
Development of over 2,000 square feet of new impervious area since July 1977 requires an on-site drainage
system. Impervious area includes: building pad with cave overhangs, paved or graveled areas, solid surface
decks, patios, walkways, breezeways, awnings, accessory structures, sidewalks, and driveways. Submit three
(3) drainage plans, scaled 1"-20', showing all impervious area with square footages as well as the location of
the proposed drainage detention system. Attach three (3) copies of the drainage worksheet (See Handout
#E72). Note: The plan must provide for temporary and permanent erosion control and must include footing
drain details.
