Re: Plan Check: BLD2020-0902
Project Address: 7821, 175t' St SW
Project: DANIALI-Retaining Walls (Revised)
I posted a revised version of my drawings. After detail inspection of the exciting wail, I
decided to remove all rotten timbers. Most of these timbers were located along top two
rows. These rows were not in contact with soil therefore 1 eliminat:cd them. Addition
steel rods were used to provide more lateral supports for the remaining of the wall (24").
Also, I moved the Wall No. 1 and located it behind the existing wall. Wall No. 2.
Remain unchanged.
Please consider the followings as my responses to your itemized comments/questions:
1. The soil report suggested that the walls be designed by a registered Profession
Engineer (page 5, Paragraph 4) not by Nelson Geotechnical Associates (NGA). I
am a Registered Professional Engineer (PE) in State of Washington. I have a
Ph.D. in structural engineering and taught structural Design and soil mechanics
courses at the University of Washington for 20 years and 18 years at the
University of Texas. I designed many heavy civil engineering structures. My
latest project was a massive pump station for the Drainage District 7 (DD7), Port
Arthur Texas. The United States Army Corp of Engineers (USAGE) in Galveston
Texas appiuved the design.
2. 71-,e Structural Design is attached.
3. Number Two (#2) Cedar lumbers will be used in this project.
4. High strength (5000 psi) Ready Mix concrete will be used. Based on my
previous experience, the mix will provide allowable compression strength of
2500-3000 psi after less than 14 days.

5. Three-inch galvanized wood screws or 359 galvanized 10d nails will be used to
attach 2x6 lumbers to the posts.
6. Nelson Geotechnical Engineering firm is already hired inspecting this project. A
copy of their contract is attached.
Inspection:
1. Erosion Control
A total of 1.4 cu-ft of soil will be augured out of each hole which yield to a total
of 29.3 cu-ft of soil per wall. According to the soil report most of this soil is
made of said. I Aill collect mid protect the spoil soil by using Heavy duty plastic
bags. Later, I will used them as a part of the needed fill.
2. Grading/Soils
The site is almost flat, and it will be covered with new fill made of crashed stone
:;and. Tl_e caa.;: ed st€.ine wlsl ci7eate a shallow rlefleh DiainNvllich
will help fast drainage of the site
3. Retaining Wall Installation
NGA is hired to inspect wall installation.
4. R01-ainiin g, Wall D e nee v
The drainage system will be made of 3" diameter perforated, and solid PVC pipes
as shown on Drawing No. 4. EI shape pins made of #4 rebars will be used to keep
the pipes in place. Drainpipes will be terminated inside the property lines after
passing through tow partially embedded concrete masonry blocks. NGA will

Standard of Performance; Disclaimer of Warranties
Subject to the limitations inherent in the agreed scope of work as to the degree of care, amount of time and expenses to be incurred, and subject to any
other limitations contained in this AGREEMENT, NGA will perform its Services consistent with that level of care and skill ordinarily exercised by other
professional geotechnical engineers under similar circumstances at the time the Services are performed. No warranty, express or implied, is included or
intended by this AGREEMENT. NGA oliers difiereiit levels of geutechiticai eng4t!eying services to suit the desires aitd needs of diflererit clients. Aliliuugh the
possibility of an error can never be eliminated, more detailed and extensive services yield more information and reduce the probability of error, but at
increased cost. CIIENT must determine the level of service adequate for its purposes. CLIENT warrants that it has reviewed the scope of work and has
determined that it does not need or want a greater level of services than that beingprovided.
Unanticipated Conditions, Hazardous Materials
Subsurface conditions may vary from those encountered at the locations where surveys or explorations are made by NGA. Because the data, interpretations
and recommendations of NGA are based solely on the information available to NGA, limitations on available data will result in some level of uncertainty, and
therefore risk with respect to the interprPtarir- of environmental, UPological and geotechnical rnnditions, despite the tise of dice prclkssional care.
During the performance of NGA's field services, if any unforeseen hazardous waste substances or elements are encountered, which in NGA's judgment may
significantly affect the scope of NGA's services or present a risk to the health of its personnel in providing the service, NGA will promptly notify CLIENT.
CLIENT understands that NGA's services under this AGREEMENT are limited to geotechnical engine: ing\engineering geolosy and that NGA has no
responsibility to locate, identify, evaluate, treat or otherwise consider or deal with hazardous materials. CLIENT is solely responsible for notifying all
appropriate federal, state, municipal or other governmental agencies, including the potentially affected public, of the existence of any hazardous materials
located on or in the project site, or located during the performance of this AGREEMENT. The existence or discovery of hazardous materials constitutes a
Changed Condition under this AGREEMENT. CLIENT agrees to indemnify and hold harmless NGA, its employees and agents against any and all claims, suits,
liability, damages, injunctive or equitable relief, expenses, including attorney's fees or other loss which arise from, or which is related to the existence,
disposal, release, discharge, treatment or transportation of hazardous materials, or the exposure of any person to hazardous materials„ or the degradation of
the environment due to the presence, discharge, disposal, release of or exposure to hazardous material.
Third Party Reliance Upon Reports
All Documents are prepared solely for use by CLIENT and may not be provided to any other person or entity without NGA's written consent, nor may they be
mentioned, communicated, disclosed or referred to in any offering circular, securities offering, loan application, real estate sales documentation, or similar
piuruuiiuiidi inaieiidl, 5wiiiiuui tale express wiiiieti auibutitdiiuii of NGA. CLIENT agrees tar deieiid, hide:mim, and hold liamiless NGA, its uffiLets,

No other party other than CLIENT may rely, and CLIENT agrees it will make no representations to any party that such party may rely, on Documents without
NGA's express written authorization.
Dispute Resolution
Ail disputes between NGA and CLIENT will be subject to mediation. Either party may dernand mediation by serving a written notice stating the essential
nature of the dispute, the amount of time or money claimed, and requiring that the matter be mediated within forty-five (45) days of service of notice. The

person or organization as the parties agree upon.
No action or suit may be commenced unless the mediation did not occur within forty-five (45) days after the service of notice, the mediation occurred but did
not resolve the dispute, or a statute of limitation would elapse if suit was not filed prior to forty-five (45) days after the service of notice.
