It is my understanding the modification you have requested to be made to the detention pond for
the subject project have been addressed by our consultants and direction has been given to the
contractor to execute the work. Because the work required by this effort is weather dependant, a
specific schedule for completion is difficult to predict. It is the Edmonds School Districts
intention to proceed with this work as weather will allow.
As this activity has been listed as needing completion before the issuance of a Certificate of
Occupancy, I request this requirement be lifted giving my assurances to the City of Edmonds the
work will be performed at the earliest possible date.
Please contact me if you have any comments as it relates to this request.

One. of the items on your punch list from 9-6-00 at Chase Lake School is the installation of the
emergency over flow spillway at the Storm Detention Pond.
A change in grading over the play fields east of the detention pond has made the original location
unworkable. We would like to propose installing the over flow at the southeast corner of the pond, the
invert at the elevation proposed on the permit drawings, IE-423.36. (see the attached sketch)
Local conditions may require building up a berm along the south property line to protect the adjacent
property owners. 'rhe existing Catch Basin at the south property line is the local low the overflow will
drain to.
Mease review this proposal or pass it on to the appropriate person(s) at the City. We would like your
approval or comments and suggestions as soon as possible to complete this work.
Thank you,
Ken

Jim,
Due to conflict with the new storm sewer system already installed, the proposed sanitary
sewer alignment exiting the north side of Chase Lake Elementary School has had to be re-
routed to the west and south to connect to the sewer main entering the site from 84th Ave W.
We have investigated other options in an attempt to maintain the flow to the north, but the
lack of cover and shallow slopes required of both the storm ernd sanitary systems prevent this
approach.
This new design will require the installation of one new sanitary sewer manhole and
approximately 125-feet of additional 8-inch pipe.
The sewer will pass under the water fine parallel to the west side of the school building. We
have determined that the invert of the sewer line will be approximately elevation 420.1 and
the invert of the new 8-inch water main will be 421.8, this will provide approximately 1-foot
of separation between the two pipes.
We intend to provide as notes to the contractor section 2.414 (see attached) from the
Washington State Department of Ecology Criteria for Sewage Works Design.
Please see the attached sketch for more details.
Please contact us with comments or questions.

a It is laid in a separate trench; or, it is laid
in the same trench with the water line that is
located at one side on a bench of undisturbed
earth; and
b. In either case, the elevation of the'crown of the
gravity sewer must be at least 18 inches below
the invert of the water line. When this verti-
cal separation cannot be obtained, the gravity
sewer shall be constructed of materials and
joints that are equivalent to water main stand-
ards of construction and shall be pressure
tested to assure water tightness (as per Sec-
tion 3.46) prior to backfilling (see detail
2.4).
2.413 Vertical Separation (Perpendicular)
Sewer lines crossing water lines shall be laid below
the -water lines to provide a separation of at least
18 inches between the invert of the water pipe and
the crown of the sewer, whenever possible.
2.414 Unusual Conditions (Perpendicular)
When local conditions prevent a vertical separation as
described in 2.413, the following construction shall
be used:
; 0 a. Gravity sewers passing over or under water lines
shall be:
1. Constructed of material described in
Table 1. The one segment of the maximum
standard length of pipe, (but no less than
18 feet long)r shall be used with the pipes
centered to maximize joint'separation.
2. Standard gravity sewer material encased in
concrete or in a 1/4" thick continuous
steel casing with all voids pressure -grouted
with sand -cement grout.
3. The length of sewer pipe shall be centered at
the point of crossing so that the joints
will be equ ' i-distant and as far as possible
from the water line. The sewer pipe shall
be the longest standard length available
from the manufacturer.

Roy, attached is some infoftom the design Eng.
regarding the relocation of afire hydrant on the East
side of the schoolproject. This hydrant relocation was
not apart qf the original plan. They want to move it 15'
to the north and raise Its elevation. Not noted on thefax
is that we are now requiring them to replace this
substandard hydrant with a new one. (only because they
opted to move It). I have notyled Florendo of this
additional requirement.

SUBJECT: Pedestrian Safely Issue — 216 1h Street SW at 84'h Avenue Wes
GARY HAAKENSON
MAYOR
It has been brought to the City's attention that there is a pedestrian safety issue along
216th Street SW at the comer of 84h Avenue West. Pursuant to our conversation, City
staff has monitored the area for parents that are lining up on 216th and dropping off the
children. The children then walk to Chase Lake School and are not observed to be
waiting for a Madrona school bus. Reg Clarke of Edmonds School District
Transportation is verifying any conflicting bus area pick up points.
At this time we are asking your assistance in notifying the parents that this drop off point
is not consistent with the traffic plan provided by the School District and promised to the
residents in the area. There is also a concern for child safety at the crosswalk area.
If you would like assistance in discussing traffic safety with the parents, the City will be
happy to assist you with that program. Please call me at 425-771-0220 if you have any
questions or would like to request help with this task

SUBJECT: Review of Traf-fic Impact Analysis — Chase Lake Elementary Schoo
Dear Mr. Flaherty,
At your request, the City has completed a review of the Traffic Impact Analysis Report of
Chase Lake Elementary School. Below is a summary of those findings.
Per the 1995 Transportation Comprehensive Plan designation, 80 Avenue West.
is a collector/arterial street. This means that the road is planned to collect traffic,
as an arterial'.
Traffic counts taken the week of 7/25/00 average 5515 a day.
Per the City of Edmonds 1992 counts,.the average was 53-9D a day.
The Chase Lake Report contains higher peak traffic counts compl eted in 1999
than are currently using 84th Avenue West.
• Per your statement, the Community Transit (CT) bus stop has been at the same
location at least for the length of your residence there (5 years)., -
• The Chase Lake entrance is at the same location as before construction, with a
modification for an entrance and an exit to alleviate circulation conflicts.
• The Level of Service projections at the intersection were completed by the School
District's Engineer. The City concurs with this analysis.
• The transit system in the 1995 Transportation Comprehensive Plan �designates a
transit system on 84th Avenue West. Transit systems are designed- to relieve the
use of Single Occupancy Vehicles.
• 84th Avenue West is identified in the 1995 Transportation Comprehensive Plan
for proposed improvements at 3.1 million dollars (1992 dollars).
• 84th Avenue West is not currently on the City of Edmonds 6-year Transportation
Plan but is prioritized to be added in the years 2006, to 2010. This prioritization
will be reviewed in 2001.
84th Avenue West is proposed to be added to the City of Edmonds Comprehensive
Walkway Plan.

0 There was a public process prior to beginning the Chase Lake Elementary School
project. The public process was from April 7 through April 21, 1999. Enclosed
are copies of your letters in support of the site drawings and commute trip
reduction.
0 The City will be meeting with the School District to discuss school children
crossing issues and improvements.
The City supports the existing bus stop location as evaluated and designated by CT, with
a recommendation of a pedestrian landing improvement at that location. There is, 60 feet
of City right-of-way at this location.
The City of Edmonds has a neighborhood traffic -calming program; however, we need a
volunteer to serve as the neighborhood representative. If you feel this is something you
would like to do and would like more information, I will be happy to send that to you.
Please feel free to contact me at 425-771-0220.

RE: New Chase Lake Elementary Project
Dear Mrs. Johnson:
I have seen the preliminary drawings of the proposed new chool and with to reiterate our
concerns and wishes as homeowners residing across the street from Chase Lake Elementary.
It is our desire, as I believe you have indicated as well, to keep the new school aesthetically
pleasing as well as functional.
I attended the City County Hearing on September 14, 1998. The City Council passed the
rezoning application by the Edmonds School District to change the current zoning from residential
to public.
We would like to highlight the following issues for consideration during your planning meetings
with the School District for this project:
• Maintain the current buffering mechanism by having the school buildings set away from
streets. This would create a transitional zone that provides for the safety of the children and
cuts down on noise. . th
• Put parking behind the school, leaving a greenbelt or play area along 84 Avenue.
• If parking must be put adjacent to 84th Avenue West, provide an extensive buffer and beffn
along 84 �h �venue West with a minimum landscape setback of 25 feet. Now that the. property
along 84 th Avenue West has been zoned Public, the minimum requirement for landscaping
setbacks to be maintained is only 10 feed along a public street as per Edmonds Community
Development Code, Chapter 16.80. th
• Add additional trees and foliage along 84 Avenue West to filter the view of a parking lot and
maintain a park like setting.
• Keep as much existing tees and foliage as possible.
• Use directional sodium lights that provide illumination for the parking lots and do not impact
the neighboring residential areas.
I have appreciated your willingness to work with the neighbors towards resolution of our
concerns. I will be attending the open house on Thursday evening and intend to provide input at
that time as well. Thank you for your interest and assistance on this matter.
Sincerely,
Patricia Flaherty

Re: New Chase Lake School
To Whom -It May Concern:
As homeowners in the Chase Lake area we support the new school facility ff the
plans for the school are the same as the site drawings supported by the Chase
Lake Site Council last fall.
However, regarding the variance for the parking, we have some concerns and
questions. What is the normal allotment of parking spaces for a school the size of
Chase Lake and how many spaces over the allotment are being requested? Why
is a variance necessary? Has the State Commute Trip Reduction plan for state
employees been taken into consideration with these plans? �
We would like to see as many parking spaces set back into the school yard area
as possible, on the north side of the school where parking exists now.
We shared our concerns with the principal at Chase Lake, Pat Johnson, VaW
participated in the.planning meetings with the School District. A copy of our letter
to her from last fall is attached and our concerns have remained the same.
Sincerely,.

Dear Ms. Zukowski and Mr. Carlstad:
I represent the Flahertys concerning Chase Lake Elementary ingress/egress and
the Community Transit bus stop on 84th. By now, you are familiar with how the convergence of
these two factors impacts the Flaherty's property, as well as the safety of pedestrians in the area.
I want to emphasize, from my legal standpoint, the troubling nature of this
situation. On the practical side, the City's decisions are forcing the Flahertys to take
extraordinary steps to protect their own children. Further, the family effectively will be held
caliiiVe� w ith"ift their lidifte during peak traffic hours. In fact, I now understand that the City has
asked the-Flaherty.'s to move their driveway to accommodate the City's decisions.
Legally speaking, the City has created a public nuisance and has inversely
condemned the Flaherty home by virtue of this combined action. Mr. Flaherty no doubt will
blanche at the threatening nature of my legal claims, as he is looking to work with the City
toward a solution, but I fear the City is taking advantage of Mr. Flaherty and his family.
If there remains a possibility of working with Mr. Flaherty toward a solution, I'm
all for it. If not, please have your legal counsel call me. Thank you.

Edmonds, WA 98020
Dear Ms. Zukowski,
FiECEIVED
J 0 L 13 2000
I-zNGINMING
Thank you for your letter of July 5 th and the Traffic Impact Analysis. In going over
the Traffic Impact Analysis, my attorney, Michael McCormack, and I noticed that there is
no mention whatsoever of the new Chase Lake School full entrance traffic impact on my
residential driveway on 84 th avenue West. Page 17 of said study explains: " the parent
drop-off area will be accessed via the south full access driveway on 84 th Ave. W. The
south access will provide a "drop off loop" for parents' The loop will enhance the parent
drop-off circulation and separate bus/vehicle traffic conflicts." Further, the map on page
17 of said report clearly shows the south full access driveway exiting opposite my
driveway and the CT stop — yet remarkably there is no mention whatsoever of the traffic
conflicts impacting my property and driveway access, or the CT stop. In essence these
are the issues I addressed to you in my June 18 th letter. This we believe to be a blatant
oversight, and we are pleased the city of Edmonds is reviewing this study as stated in
your letter.
The survey you sent me is thoughtful and thorough regarding past traffic
problems at the old entrance at 216th, however it misses the mark and is not germane to
issues I brought up in my letter to you of June 18 1h regarding the new traffic and safety
concerns. The moving of the Chase Lake full access driveway from 216 th street
southward on 84 th Avenue West opposite my driveway and CT stop has cre ' ated an
entirely new traffic flow situation that has no history. The moving of the entrance has
created a new confluence of traffic congestion involving the new school driveway, the
existing CT stop and my existing driveway. Each of these access points in themselves
does not seem to pose a problem, however, all three of these points together I believe
creates a serious safety and access threat, and accident waiting to happen.
In regards to your survey I suggest you visit me at the site in question, as Dave
Orviss of the city council has done at my request, and see the escalating traffic
conditions for yourself. We have serious traffic and access issues that I wish to
neutralize before the opening of the school season. Further, in response to your survey
I can tell you that I have lost two mailboxes across the street from the new full access
school driveway. Washington Trucking will be reimbursing me to move my mailbox from
its present location across from the school driveway, as they destroyed the old mailbox
three weeks ago. We thank God it was our mailbox and not one of my four daughters or
God forbid a child or adult at the CT stop. Further, the Edmonds Police Department has
ticketed speeding motorists regularly in front of the school. The 620 and 621 transit stop
on the half-hour at the hours in the morning and afternoon to add to traffic confluence,
which is why we are requesting that the Bus stop be moved. I hope this information is
helpful.
Lastly, I am very concerned about the safety of children, so I will be contacting
you regarding the fencing in of the front of my property to protect my children from the
0 0
developing traffic situation. I am pleased the city is considering a second traffic impact
analysis, and my wife, or I would like to see you for a site visit as soon as possible.

Dear Mr. Fiene,
I am writing you regarding the Bus Stop in front of my home at 21608 84 th th
Avenue West and the Bus Stop across the street from my neighbor's home at 21524 84
Avenue West in Edmonds.
The recent remodel of the Chase Elementary School has positioned a school
entrance/exit directly diagonally across from my driveway. In addition, there is a transit
Bus Stop in front of my home at 21608 84 th avenue West. This Bus Stop, coupled with
the elementary school entrance -exit across the street has inadvertently created a traffic
safety issue overWiit:h+�m deeply concerned. The same is also true for my neighbor,
2)) th
Mrs. Marilyn Gunderson,at 21524 84 avenue West who has a transit Bus Stop and
school entrance7exist directly across from her home. These Transit Stops and school
entrance/exits will congest traffic and students in the early morning and afternoons in an
area less than 75 yards creating in my opinion a traffic pedestrian accident waiting to
happen when school opens in the September of 2000.
Further, I have four daughters; two who have already attended Chase Lake. My
twin's girls will attend the school in a couple of years and I am deeply concerned for all
of their safety, as well as the safety of the other children due to this traffic concentration
in such a small area. I am enclosing the front of my property to protect my children
because my property is at the heart of this traffic congestion, but what will protect the
other children and people waiting at the Bus Stops? In addition, I am also concerned
about the safety of my driveway access to 84 th Avenue with the Bus Stop and School
traffic piling up in front of my driveway sandwiching the entrance in the early morning
Bus and school traffic as my wife and I leave for work.
These concerns lead me to respectfully request that you do a traffic feasibility
study to address these pedestrian and child safety concerns, and street access
concerns that I raise. I request as a start, that you move the Bus Stops in front of my
home at 21608 84 Avenue West and Mrs. Gunderson's home at 21524 84 Avenue West
to another location to alleviate the traffic and safety concerns that I am sure your traffic
feasibility study will confirm. This in itself may remedy the problem, but please let me
know what other solutions you think would ameliorate this situation. I am surprised the
original traffic impact study did not see this glaring problem. Please have your
representative contact me at your earliest convenience regarding these concerns and
what the city intends to do about this matter.

Dear Mr. Flaherty,
GARY HAAKENSON
. MAYOR
At your request, the City has contacted Community Trans . it (CT) regarding the bus stop locations on 84,h
Avenue West near Chase Lake Elementary School. CT previously evaluated the bus stop locations and
has given the City the following information.
• The buses. run every thirty minutes on this route.
• This route does not have a high ridership.
• The stop will possibly be used by staff at Chase Lake Elementary, thus reducing additional Single
Occupancy Vehicles (SOV) on 846'Avenue West.
• Elementary children do not typically use CT
• A stop relocated to the north or to I the south would incur additional pedestrian vehicle conflicts.
• These stops will not cause a significant traffic disruption.
Therefore, at this time, the request to relocate is not advised by CT. If this does become an issue at the
beginning of the school year or for any other issues, please contact CT and the City...
As you requested, you will find enclosed a copy of the Traffic Impact Report for this project prepared by
the School District's Engineer. This information was available during the public process of this project
and expressly evaluates the traffic conditions incurred by the school. It contains information that. is very
technical, and I would be happy to interpret that information for you in our office.
Please also note that your letter and a copy of the report will be forwarded to- the School District
Representative, Brett Carlstad. The School District should also be able to respond to your questions and
. cohcems. If you feel that an additional traffic study should be completed, I can coordinate this with the
School District; however, I will need at least thirty days to complete this task.

Dear Mr. Porter,
BARBARA FAHEY
MAYOR
Yesterday I spoke on the phone with Florendo Cabudol from your office. He asked that I
write a letter based on our conversation. Isince discovered that the information I gave
him was, in this case, erroneous so this letter should help clarify the issue.
When the public water main is existing, the City of Edmonds Water Division crews
perform the tap on the main and set the meter at the property line. The fee that the City
charges varies depending upon the size of the service and the size of the meter.
The exception to this instance is when the developer is installing a watermain. In that
scenario, which is the case on this project, the developer/owner/contractor installs the
main, taps the main for the service and sets the meter box: The City of Edmonds Water
Division then provides the meter to the developer at a cost that is reflective of the reduced
amount of City time.
If you have any questions, please con, me at (425) 775-7744 or Jim Waite, Water/
Sewer Division Supervisor at (425) 771-0235. Thank you.

Re: Your letter of August 14, 1998
Dear Mr. Warden,
In your letter of August 14, 1998, you mentioned that the School District and its engineering consultant were
confused as to what the storrn water detention requirements were for the proposed Chase Lake Community
Learning Center. Back in March of 1997 when I spoke to the School District's engineering consultant, I made
our requirements quite clear. At that time the consultant was unsure whether the existing foundations were to be
left intact for the project, or if existing buildings were to be totally demolished with new buildings constructed.
He believed th6 existing foundations would be kept intact. I told the engineer at that time that the requirement
regarding detention was dependent on whether the project was a remodel or redevelopment. I also mentioned
that the City had a documented interpretation regarding this matter, that we could copy and send them. This is
the standard practice for such a project, and the City has not deviated from that standard.
Attached is a copy of that interpretation for your reference. Also attached is a copy of sections of the
Washington State Department of Ecology Storm Water Manual regarding redevelopment, which is also
consistent with our interpretation. Additionally I should add that I have had numerous conversations with not
only the engineer but also Roger Schultz at the Edmonds School District regarding this issue, and they both
seemed to have a clear understanding regarding our requirements.
In response to the issues you raised in your letter; 1) The Seaview Elementary School project completed last
year was not considered as new impervious, because we were told that the existing foundations were used
throughout the project. 2) The Edmonds Woodway High School project process began before implementation
of our new Storm Water Management Ordinance. 3) Regarding neighboningJurisdiction requirements, I do not
believe that any of the municipalities bordering Edmonds have adopted the State/Department of Ecology
requirements. I would be interested in reviewing any redevelopment policies from other agencies that have
adopted Ecology's manual or standards.
I hope this clarifies the requirements, and that this information will be used when planning future projects. If
you have any questions or you would like any further infori-nation regarding this matter please do not hesitate to
contact me. Thank you.
Sincerely,

RE: Chase Lake Community Learning Center
Detention Facilities
Dear Mr. Fiene,
The Edmonds School District is preparing a new construction prograrrL to replace the facilities at the
subject project. Our consultants have met with you with regard to the handling of storm water as a result
of this development. We have also met with you and others in your offices to discuss the requirements of
the City of Edmonds in our proceeding with this program
During the building evaluation phase of the project, our Civil Engineers, Coughlin Porter Lundeen,
contacted the City of Edmonds to review the design criteria and impacts based upon the options to
renovate or reconstruct. In those conversations with you as the City of Edmonds Hydraulics Engineer, it
was indicated that the City of Edmonds has adopted the DOE manual for storm water quality and quantity
control. Also indicated, per the City of Edmonds adopted code, the threshold for both water quality and
detention was the increase of new impervious greater than 2,000 square feet. (See attached
correspondence record dated 3/11/97). The project design currently does not increase the overall site
impervious area over existing developed conditions.
The confusion is what the City was considering "new" imperious and their definition of re -development.
In the discussions of March 1997, the City did not indicate that they would consider the impervious
surface replacing the existing impervious surface as Anew@. Based on this information, Coughlin Porter
Lundeen was given the impression that storm water detention would not be required for this project. We
had no reason to question this interpretation since detention was not required for either Seaview
Elementary or Edmonds/Woodway High School. Both these schools have similar design aspects with
respect to storm water control as Chase Lake Elementary.
Subsequent interpretation for Chase Lake Elementary by the City of Edmonds has now made both on -site
detention and water quality a requirement of the proposed development. This interpretation, as a result,
has a significant cost impact on the project site development. and in turn, the total cost of the project.
Th e* Department of Ecology (DOE) Storm Water Drainage Manual currently imposes the most restrictive

and extensive storm water control regulations. The DOE Manual requires the developed 2 year/24 hour
design storm to be released at one half the pre-existing the 2 year/24 hour design storm, the developed 10
year/24 hour storm at the pre existing 10 year design storm, and the 100 year developed the pre-existing
100 year design storm. An additional safety factor of approximately 30 percent is required to be added to
the size of the design facility. Many neighboring jurisdictions adopting this manual allow for the use of
existing conditions (the existing storm water runoff is based upon existing developed conditions instead of
pre' -existing undeveloped conditions).
These storm water requirements for the project have impacts to the site plan, project construction budget,
and design fees since no detentions system was anticipated based upon the building evaluation study.
The actual increase in construction cost associated with the detention and water quality improvement is
dependent upon the final design of the detention and water quality facilities. The additional impact to the
project as a result of your interpretation will result in a cost increase in the range $250,000 to $400,000.
depending on whether the design solution is a pond or an underground structure.
The Edmonds School District requests a ftu-ther review of these interpretations and encourages your good
offices to work with the District in developing a position which has less cost impact to the public and the
neighborhood which this facility will serve.

Dear Mayor Naughten,
In the attempt to change long adopted policy and practice,to shut off school
access to 21.5th Street S.W,,the names of several city employees have been
used as authorities to legitimate denial to elementary busses and the children
using them...'I-wi.sh to communicate the following to yourself and to them.
As expressed in the communications to the petitioners and to the parents of
our children that are attached for your information, I remain completely
confident of the support of the Edmonds Police officers and the city
government employees.for the welfare and rights of school children. I can
not know how the decision will go. The School Board will make the judgment
based on the total welfare of students in the school district as well as
those in our particular school. However, in the midst of the quotes and
counterquotes, I would like your employees and the officers to know how much
we have valued their past services and remain confident of the same quality
in the future.

December 12, 1986
To: Parents and Chase Lake Students
From : firs. Park, Principal
Concerning: Attempts to permanently close off access to public street.215th
As you know from the article in the Enterprise and communications from
our Chase Lake PTA Executive Board, a small group of parents to the north of
the school decided unilaterally, starting October 29th of this year, to shut
off use of the public access to 215th street to Chase Lake children and their
school busses. Since 1969, as stated in the original request from the residents
in this particular neighborhood that a gate should be installed to limit traffic
after school hours, busses and related school traffic would continue to use the
right of way.
From the day that one of the residents parked a truck to block the exit,
we have hoped that patience and forbearance would allow time for reason to
prevail in this attempt to discriminate against our children. Unfortunately,
such has not been the result.
It has been our practice to keep you as informed as possible of events here
at school. While we try always to emphasize the positive, we find ourselves
dealing with a firsthand experience in negative application of the social and
political- elements existing in communities. The issue is very clear. Are our
children second class citizens and implicit -dangers which have to be isolated
from public areas?
To the principal of Chase Lake, respons ible for the health, safety, human
rights and education of your children, this is an unacceptable position. You
have done an excellent job of training students to be responsible. We are
doing an excellent job here at school. The behavior of our students is exemplary
and the best testimony to those facts.
Our school district and its related departments such as transportation
do a outstanding job. Many of you personally know the quality of performance
and service provided by our bus drivers. It is beyond my understanding that,
in the Cit
I y of Edmonds, in 1986, any person should accuse our children and their
transportation of being a threat to any neighborhood. It is my experience that
our children are an honor to serve and a joy to be around. The bus drivers are
well -trained and conscientious.
Therefore, I have sent the attached statement to the residents whose various
family members are presenting their petition to change the present policy and
p,-actice so that the access to 215th be permanently closed. I do not know what
the result will be after consideration by the School Board on December 16th.
However, with this statement, my opinion of such accusations and proposed actions
should'�e clear. 'I w:i 11 send that information as'we ai'6�'giVeh di�ett_ion a's
the result. If you have an opinion or an experience you wish to state, please
send that to the PTA Executive Board,at- Chase Lake, They will be willing to
see that it reaches the School Bcard imeetinq in time- for consideration. The
School Bocard meeting comes tho sl--me eveni ng as our winter music program, but is
at a slightly later time. You would be welcome to attend if interested in the
discussion.

Gillihan, and Hacker
From: Laura Park, Principal
We have received.from the Superintendent- a copy of your petition to the
School Board. Our staff examined it with some interest doe to the fact that,
in some cases, their children went through Chase Lake 13 to 15 years ago when
many of your children did. They were happy to see that these members of your.
families known to them seem to be well, although there was some difficulty in
identifying their signatures as they were spread across the several pages of
the petition.
I was personally disappointed that there was no recognition of the factual
information provided where our school has received direct contact from you.
There is also no recognition of the two years of effort to solve traffic prob-
lems from which you were the chief beneficiaries, and for which to date we have
received abuse, insult and harrassment. It is always disappointing to provide
extra consideration for people and then find it is wasted effort.
As of the last School Board meeting, we had some hope that you were begin-
ing to see that the children and the parents Chase Lake serves are entitled to
concern for their safety. We would welcome any assistance with the situation,
however, it is difficult to take seriously your plan to have Chase Lake's gate
used to shut its people inside, away from public access that fronts your property.
This is not a new idea. It was tried in the Middle Ages and thus we have the
work "ghetto". It was tried again in South Africa's "compounds". We simply
don't believe that such an idea or practice is appropriate in Edmonds, Washington,
in 1986.
We do no '_ be I i eve t h_at_ el ement. a ,v children and their transport threaten the
L -11
safety of any neighborhood, and especially yours. Your street is 12 feet wider
and the pavement is in better condition than the other exit our school also uses.
In fact, it is wider and the pavement is better than many streets across the
City of Edmonds. There is no problem with heavy traffic coming from both direc-
tions as with our other exit. Our bus drivers have a superior safety record
using all their routes in South Snohomish County.
You make references to a particular Edmonds police officer and an Edmonds
City employee as authorities supporting you plan to isolate Chase Lake Elementary
School.. I find it hard to believe that the officer is going to be any more
willing to discriminate against our school children than the others on the Edmonds
Police Force with whom we have had regular contact. I personally have found all
of them very interested in the welfare of our children and highly supportive of
their rights. As to the city employee cited, I doubt that he will have taken
the position that school busses are a danger to your neighborhood when he knows
the next questions will come from all the other homeowners whose property fronts
streets in the City of Edmonds used by school busses. They will want to know
why they are not receiving equal consideration if school busses and elementary
children are a danger to the community. (continued)
p. 2
We know that ours is a school where parents expect responsible behavior of
their children, and that is reflected in a school population with almost no
discipline problems and no vandalism. We believe that our children are entitled
to the same respect and consideration that 'they give others. In our view, they
are the greatest resource our country has.
Our children have watched and read about your activities with interest and
puzzlement. We teach principles of American law and government very carefully.
Our children were just recognized by the Edmonds VFW as district winners in their
essay contest on the theme "What Liberty Means to Me". Quoting one of our children
from a Southeast Asian country, "There was no liberty to go where(she) wished to
go in (her) country and here there is freedom". It is an exceedingly great puzzle
to them, in a cou ' ntry where there is supposed to be "liberty and justice for all
that a few people can decide on the basis of no evidence that Chase Lake children
and their busses are a threat to neighborhood safety. It is a puzzle to tile, also.

of the reasons teachers teach in the face of abuse, insult and disrespect for their
work.
A child is a person who -is going to carry -on what you have started.
He is going to sit where you are sitting, and when you are gone, attend
to a"i"I t-hose things you think are ii-iiportant.
You may adopt all the policies you please, but how they are carried
out depends on him. He will assume control of your cities, states, and
nations. He is going to move in and take over your churches, schools,
universities and corporationF,.... The fate of humanity is in his hands.
This fact of life stated by Abraham Lincoln is one of the basic precepts
by which we measure our teaching of students. We know that our children learn
every hour cf1 the day, not just between 8:30 a.m. and 3:00 p.m.. What have they
learned from this case that will affect their attitudes and decisions? The
citizens of the community are responsible wit1h teachers and schools for the quality
of life created as the result of actual experience students carry forward and
from which they build our future. It is ironic that the City of Seattle has a
campaign to become known as a "kid's place" and in Edmonds there is a proposal
to keep them 0Ut of a neighborhood.

MEMO TO: Ronald L. Whaley
M.A.A.
FROM: Leif R. Larson
City Engineer
SUBJECT: Street Right-ofwway at Chase Lake Elementary School
In the early 1960's, the City annexed the school property
prior to the construction of the school. At that time there was a
20-foot right-of-way running through the property dedicated under the
old Alderwood.Manor No. 9 plat. The school District came to the City
with a request for vacation of this right-of-way and propos'ed the dedi-
cation of the orange area indicated on the attached map. The records
of the City did not reflect a requirement that this property be dedi-
cated as a condition of the vacation of the 20-foot right-of-way.
There is no record that the orange area was ever dedicated for right-
of-way. At this point in time, there is an improved street within the
orange area which is barricaded and used only for school access. We-,
-therefore, do not see the need for the street being dedicated at this
time for public right-of-way. However, the portion proposed to be
dedicated that lays within the proposed right-of-way for 84th Avenue
W. is required.'
With your concurrence, we will contact the school district
and request that ' this dedication be made in light of proposals that
they had made during the previous street vacation action.

1r.AT ALL PRACTICALp I WOULD LIKE TO HAVE THF. FOLLOWING ITE143 INCLUDED ON
T,--ic AGENDA OF THE STREET COMMITTEE MECTINQ MARCH 20 1964.
EDMOND3 SCHOOL DISTRICT NO. 15-HAVE ACQUIRED A SITE FOR CONSTRUCTION OF
CHAsL LAKE ELEMENYARY SCHOOL IN THE VICINI7Y OF 2216TH ST. S.W. UETWEEN..82ND Avc.
W. AND 84TO AVE. WESTP AS INDICATED ON THE ATTACHED PRINT, FOR UTILIZATION OF THIZ
siny ZT 13 NECESSARY TO VACATE A 20-FOOT WIDE STRIP OF UNIMPROVED R;GHT-OF-WAY OF
216TH ST. 5,14. AS SHOWN IN RED ON THE ATTACHED MARKED PRINTSo THis STREET IS MOT
OPEN FOR SOME DISTANCE TO THE FAST AT THE SCHOOL SITES AND THE RIGHT-OF-WAY TO 59
VACAYCD 15 NOT 14USE FOR3 1-40R RhQUIRED FOR TRAFFIC CIRCULATION. MR* JRRRY HALL:
SCHOOL DISTRICT ATTORNEY� HAS DISCUSSED YHE PROPOSED STREET VACATION WITH THE COUN'TY
COMMISSIONERS., AND RECEIVVD THEIR ORAL CONCURRENCE, HOWEVER, IT IS OUR OPINION T14AT
THE SCHOOL SITE SHOULD PROPERLY BE ANNEXED TO THE CITY OF, EDMOND Ii CH
S., TO W I IT IS
CONTIGUOUS ON THE NORTH., BY REAS03 THAT THE SCHOOL WILL BE SERVED BY CITY OF EDIAONDS
SANITARY SEWERSS AND SHOULD PROPERLY RELY UPON THE CITY OF ED14ONDS FOR POLICE AND
FIRE PROTECTION, IF ANNEXATION 15 ACCOMPLISHED PRIOR TO CONSTRUCTION OF THE SCHOOL#.
TfiE BUIlLDING PERMIT FEE THEN WILL APPROPRIATELY BF PAID TO THE CITY OF EDNIONDS RATHER
THAN I'D SNOHOMISH COUNTY.
WITH THE FOREGOING FACTORS IN MIND, WE: ARE RECOMMENDING TO THE SCHOOL DISTRICT
THAT REQUESTS FOR ANNEXATION AND FOR STREET RIGHT-OF-WAY VACATION BE SUBMITTrD TO
THE C5TY OF EDMONDS AT ONCEO FOR EXPEDITIOUS ACTION BY THE CITY. IF OUR RECOMMENDATIONS
ARE CONCURRED INp IT IS PROCAOLE THAT FORMAL PETITIONS WILL BE SUBmITTED TO THE CITY
COUNC,IL AT THEIR REGULAR MEETING ON MARCH 3. THE REASON FOR EXPCDITIOUS ACTIOM ON
THE PART or THE CITY IS THAT THE PLANS FOR THE SCHOOL UUILD114GS ARE WELL ADVANCED.,
AND A CALL FOR BID3 IN EARLY APRIL OF THIS YEAR 13 ANTICIPATED. THE CITY THEN SHOULD
BE IN A POSITION TO ISSUE THE BUILDING PERMIT FOR CONSTRUCTION BY THE DATE THAT CON-
STRUCTION CONTRACTS ARE AWARDEDo
IT MAY BE t4anD FRON THE ATTACHED PRINT3 THAT 215TH ST. S.W. (A14D GTH Sir S.E.)
COMPRIS-f-'S AN EXCEPTIONALLY LONG CUL-DE-SAC STREET WITH POOR ACCESS. AT THE TIME OF
PLATTING OF SEALAwm ACRES No, 20 WE DESIGNED THE !NTERIOR STREETS TO INCLUDE All CX-
TE14SIOPI or 18TH PL. TO THE SOUTHCRLY MARGIN OF THE PLAT) AS AN INCREMENT OF A PROJECTED
COMPREHENSIVE PLA14 FOR FUTURE EXTENSION OF TNE STREET SOUTHWARD. IN COLLABORATfON IN
THC PI.ANMiwG OF SITE DEVCLOPMeNTO WE HAVE RECOMMENDED THAT A STREET EXTENSION AS
INDICATED IN YELLOW ON TH& ATTACHED PRINTS TO BE INCLUDED BY DISTRICT 15 IN THEIR
SCHOOL CONSTRUCTIOA PROJECT. OPENING OF THIS PROPOSED NEW STREET IM OUR OPINION
WILL BE MOST VALUABLE IN THe jmpitonmeNT or GE14ERAL AREA ACCESS AND TRAFFIC CIRCULATION.
THE AMOUNT OF LAMD.INVOLVED IN NEW STREET DEDICATION W14L MATERIALLY EXCEED THE AREA
INCLUDED IN THE ACQUESTZO VACATION*

Introduction
This Stormwater Site Plan has been written to support the permit documents submitted for the
Chase Lake Elementary School Relocatable Classrooms project located at 21603 84'h Avenue
West in Edmonds, Washington. The project will meet the Minor Site Requirements, as required
by the 2010 Edmonds Stormwater Code Supplement to Edmonds Community Development Code
Chapter 18.30 (referred to herein as "Supplement").
Existing Conditions
The existing site is currently developed with buildings, parking lots, and play fields serving Chase
Lake Elementary School. Stormwater is collected and conveyed onsite and generally drains
south prior to discharging to the City's public storm system within 218 th Street SW. Existing soils
are Alderwood gravelly sandy loam (Basal Till), per the Web Soil Survey (see Attachment 3). The
site is located within the Halls Creek drainage basin per the City of Edmonds Watersheds Map
(see Attachment 4).
Proposed Conditions
The project consists of the construction of one dry portable classroom, gravel building pad (for
portable building placement), and an asphalt walk for access to the portable. See Attachment 1
for a Civil Site Plan exhibit showing all new and replaced impervious surfaces and disturbed
pervious surfaces. The project will disperse stormwater via a splash block to compost and sand
amended soils. Below is a tabular summary of the proposed land use.

Project Site Classification
Based on Figure B in Handout E72 and the Site Classification Worksheet (see Attachment 2), the
project is classified as a Minor Site Project since the project will construct less than 2,000 square
feet of new plus replaced impervious surfaces, less than 7,000 square feet of land disturbing
activity, and less than 50 cubic yards of grading, fill, or excavation. No new pollution generating
surfaces are proposed.
Minimum Requirements
The project is a Minor Site Project and is required to provide a Minor Site Construction
Stormwater Pollution Prevention Plan, per Section 6.0 of the Supplement.
Stormwater Site Plan
Chase Lake Elementary School
2150007.11
OM130
2.1 Minor Site Construction Stormwater Pollution Prevention Plan
The construction documents include a Temporary Erosion and Sediment Control (TESC) plan,
which shall provide BMPs to meet the Minor Site Construction Stormwater Pollution Prevention
Practices per Section 6.0 of the Supplement and as documented below:
Plan and Implement Proper Clearing and Grading
Contractor shall mark clearing limits as delineated on the TESC plan prior to construction.
Existing vegetation will be preserved and exposed areas will be kept to a minimum per the TESC
plan.
Cover Exposed Soil
Contractor shall cover exposed soils with temporary measures before a storm event and shall
hydroseed exposed soils as soon as possible for final mitigation.
Prevent Discharge of Soil or Sediment
Contractor shall locate soil piles away from drainage facilities and shall cover with plastic sheeting
at the end of each workday.
Provide Storm Drain Inlet Protection
Contractor shall provide storm drain inlet protection at all existing catch basins located
immediately downstream from the project site. Contractor shall be responsible for maintaining
during construction and removing once soils are stabilized.
3.0 Conclusion
This analysis is based on data and records either supplied to or obtained by AHBL. These
documents are referenced within the text of the analysis. The analysis has been prepared using
procedures and practices within the standard accepted practices of the industry.

Site Classification Worksheet
Page 1 of 2
The project's Site Classification will dictate the specific stormwater management
requirements applicable to your site. Completing this worksheet will help determine the amount of
regulated impervious surface and whether your project falls into the classification of a Small Site
(Category I or Category 2), or a Minor Site. Please reference the Glossary (m). 10-11), Figures Q and
E, (pp. 8-9), and Examples (pp. 11 - 12), to assist with completion of this worksheet.
1) Is Permeable Pavement' Proposed For Use on this Site? Yes F1 No
Refer to Stormwater Supplement Chapter 5.1
If YES, the subject area is to be considered impervious for initial site classification purposes. Include total
permeable pavement area in the calculation of Non -Regulated, Replaced and/or New impervious surface
areas in the table below.
2) Determine the Amount and Type of Existing & Proposed Impervious Surface for the Site
Refer to Stormwater Supplement Chapter 2 and Fig. C
Line 1: Identify the Non -Regulated Impervious Surface Area.
Line 2: Identify the Replaced Impervious Surface Area, dividing the total between Exempt and Regulated; either or both
may be zero. Note: For project classification purposes, Replaced Impervious may only be considered exempt
under certain conditions. Refer to the Glossary and Figure D.
Line 3: Identify the New Impervious Surface Area for your project. All impervious areas created post -July 7, 1977 or
after the date of annexation into the City are regulated & should be included in this total unless they can be
categorized separately as a Replaced -Regulated area.
Line 4: Enter the sum of the total Replaced -Regulated plus the total New impervious areas.
Line 5: Identify the total area currently mitigated by an existing city -approved stormwater management system.
Line 6: Enter the sum of the value in Line 4 less the value in Line 5 to identify the total Regulated area in which
stormwater controls have not yet been applied.
Line 7: Identify the total area proposed to be mitigated through the use of Low Impact Development Techniques.
Line 8: Identify the total area proposed to be mitigated through conventional Stormwater Management Techniques.

SITE AND PROJECT DESCRIPTION
The site is occupied by the' existing school and ass6ciated,parking!and playfield. areas-.'. The existin
9
school buildings are concentrated in the central portion of the'site, A 'mix of Asphalt -'and wood chip -surfaced
play areas and sand- and grass-surfAced fields occupy the southern andeastem' portions of the site. A
generalized layout of the principal.site features -is shown on the Site Plan; Figure 2.-
Existing structures consist,of five. classroom buildings (designated Buildings A through Eon the Site
Plan),the.administration and library building, the.gymnasium and kitchen building, and, a covered play area
located to, the south of the building complex. All of the buildings are of concrete construction and all are
single -story except die gymnasium, which is equivalent to two stories in. height. Playcourts located to the west
and east and.1the covered play area to the south, of 'the building,cluster are surfaced with'asphalt pavement,.
Open areas.adjadent to and between d,i e buii I din gs a re surfaced with la wnj other planted areas,'and concr ete
walkways. Asphalt -paved parking andacce§s drives for buses And other vehicles are located in, the northwest
and northeast portions'bf the site.
The school. structures are founded on shallow tom6derately deep perimeter spread foundations with
concrete'column footings. and interior grade beams. Structural elements appear' to consist of precast and cast-:.
in-plAce reinforced concrete.' N6h-lo.Ad-bearing walls- are of gl ass And hard board panels. 'We did not observe
instances of wall cracking orany other I evidenceof differential settlement in tha,buildinis during our field
reconnaissance.. Based on'surface features and a review of the original desigin-drAwings, it appears the building
footingsaregenerall founded on- native soil, at deptlis ranging from about 3. to 8.5 ft below exisiing'grades.
Y�
-The Edmonds School -district has acquired, the re's,idential lot'dirdictly to the north of the main school
entrance. An older wood -framed house, trees,' blackbe brambles, and other vegetation occupy- this
rry
rectangularp''arcel: It is.our understanding that one or more undergrgurid.1storage'tanks, are of wer"e locatedon
this property.. A Phase Il e.nvironmental site assessment (by'othdrs) is currently underway to determine, the
status, of the tank(s) and any impacts to 'soil and/or groundwater quality.
The existing Chase.Lake Elementary School I and".house on the newly acquired - parcel Will be -
'd to make'room for the re"lacement school. The new school will be an Approximately
completely dem6lishe
p
55,000 ft, one- and two-story structure -with interior c , orri'dors , and comm , on areas' between 'the different;
functional units: We assume,that the planned finished floor elevation of the new structures will'be sirmilar to
the existing floor elevation. Th&approximateoititline of the proposed bu.ildingsi.s shown on'Figur.e 2.'.

-,explorations, identified as T?- I through T?-l2j are illustrated on the Site Plan, Figure 2. A discussion of the
field exploration and test procedures, together' with edited logs, are presented in Appendix A.
The following, discussion is based on conditions observed, in, the test *pit explorations, the res ults of
laboratory soil testing, and onsite plans showing the -pre -development and existing site topography. The site
is generally underlain by fill of varying dept4 overlying native soil of primarily *glacial origin. Thin deposits'
of buried topsoil were encountered at various test pit locations across the Site.
A review of topographic data on the grading plan for the existing school shows that the
Oredevelopment ground surface sloped downward from the east and west sides to the west -central portion of
the site. Anorth I -south trending depression centered approximately beneath existing Bui I Idings A and B'(Unit
C on the original grading plan) appears to'have drained the area toward -the 'south. Based on current site,
topography, it,appears that the depression was fillIed as part of site grading performed during construction,of
the existing schooL The depth of fill observed in the, test pits ranged from a thin topsoil layer near-Bdildings
D and E (Unit A on the original grading plan) to about4 ft nearBuildings A and B. Deeper fill maybe present -
to the south of Building B.'Inaddition to the above area, relatively small, former topographic depressions in
other portions of the Site also appear to have been filled to obtain current'site grades. Testpit TP-4 maylbe
.166ated at one such natural dep�essioii.,Jhe fillienerally consists of silty sand an . d sandy silt containing
varying amounts of gravel and organic material. The fill typically ranged from loose to medium. dense -and.
medium stiff to v�ery'stiff, and wa's'gener.ally moist.
Native soil at the site consists primarily of silty sand and sandy silt of glacial Prigin contain mig varying
amount of gravel and cobbles. Where -encountered, the sand and silt was generally moist and- ranged from.
medium dense to dense and medium stiff to very Stiff.. The density and consistency of the sand and'silt
generally improved with depth. Test.pits TP-2, TP-3, TP-4, TP-6, TP-7,, and T`P-8 appear to have terminated
in an ablation till. This ablation till is similar in ap pearance to basal glacial till encountered elsewhere I in the
site vicinity, but,'because it dropped out (ablated) as the base of theglacier melted, if does not have the density
or overall strength of the basal till. Test pit TP-5 encountered a thin layer of apparent ablation till underlain
by wet, medium dense to dense, apparent outwash sand containing varying amounts o , f silt "and gravel.
Relatively thin,(less than I Y2-ft.thick) zones of wet to moist, soft to medium. stiff. silt with varying
amounts of organic matter were encountered immediately above the ablation till. in some of the'tdsi pits. These
relatively soft silt zones may represent post-gla*cial'Efccumulation.o.f material in shallow surface depressions
within the till.. Buried topsoil was encountered beneath the fill in test'pits TP-2 and T�V4.
Slow -to moderate groundwater seepage was observed in'test'pits T?- 19� T?-2,'TP-5 and T`P-6. Where'
observed, the groundwater appeared lo be perched above more competent an1dyeilatively impervious fine-
grained soil such as the ablation till.

,CONCLUSIONS AND RECOMMENDATIONS
Based upon evaluation of the data collected during this investigation, it is our opinion that subsurface
conditions at the site are suitable,for the proposed construction, provided the recommendations, contained
.herein 'are incorporated into, - the project design. Conventional shallow. isolated and continuous footings, slab-
on- grade'. floors, and typical pav . ement sections are feasible. Undist6rbed'native site soil. or properl . y compacted
structural fill placed immediately above undisturbed native'soil will,provide adequate foundation support for.
the 'proposed structures.
The presence of buried topsoil and zones of relatively soft silt suggests that relatively little attention
was given to site preparation prior to.'plac,Oment of the existing fill. This may have been by design. The
foundation plans for,the -existing buildings.indicate that existing foundations for portions of Buildings A', By
and C were founded as much as about 41/2ft below pre -development grades. This would place. the bottom of
the footings on more competent ablation till or outwash sand, and as much as about 81/2ft below existing site
.grades.
Due to the presence of buried topsoil and softer silt, and the Possible variable nature of the existing
fill, we do not recommend founding spread footings on existing soil above the more competent natives6il.
Founding spreadfootings on competent native.soil, or structural fill. ov'ercorripetent native soil, will requite
relatively deep excavations'pAyticularly over the',western portion of the proposed building. Inaddition,
demolition of existing foundations, particularly the deeper foundations, will likely'result in relatively deep
excavations throughout- the proposed buildin 'location. Accordingly, it may be more practical for foundation
9
and slab support toremove the existing fill, buried. topsoil, and soft silt zon6s.across the building location, and
.replace those soils with-6ompacted, imported structural fill.
The native soil and existinz fill are moisture sensitive and susceptible to softening and disturbance by'
construction equipment when wet. The soil will need to be near optimum moisture content in order to, achieve
the proper compacted density. Consequently, site grading operations should ideally be scheduled fori the dry
summer andearly fall months. However,' with careful site prepwitionand the use'of select. structural fill, site
grading can be accomplished.,during other periods of the year. To prevent schedule delays, the need for
imported, -select structural fill should be 'expected regardless 'of the season since weather conditions -can be
unpredictable. The -undisturbed native soffis relatively impermeable and'is not suitable for use as ameans to
dissipate stormwater through ififiltration.
Additional- conclusions and specific recommendations regarding site preparation; foundation 'support,
'foundation' settlement, lateral earth pressures, drainage considerations, pavement'd6sigri, and seismic design
considerations are presented in,the following sections.
SITE PREPARATION
All deleterious, material such as grass, roots, topsoil,'debris-laden fill, and soft'naiive soil should be
stripped fro as to be upied by structures, pavements, ot walkways.,, The general depth of stripping
rn, are occ
required- is.,estimated to range from about 2 to, 18,inches and average about 6 inches.: We alsoxecommen . d
overexcavating existing filli buried.,tops'.6il, and'soft, gilt within the proposed building locations., We estiinate
that up to about 81/2A of overexcavati6n, primarily over the westem portion -,of thepr6posed building, ma be
Y.
required. Soil with more than about 3 percent organic matter should not be used as structural fill.'
Existing building foundations should be removed as a part of the demolition efforts. Existing buried
utilities located, within buifding areas and not slated for reuse should be removed and the.trenches properly
backfilled with'§irtictuial fiR in. accordance with recommendations presented in the fill and compaction section
of this report. For'Jocaliz'ed deeper excavations,such as a utility line crossing, a lean mix concrete may be used
as backfill undemeath,pr6posed footings in place of compacted structural fill. Any pipelines abandoned in
place should have their ends sealed with a concrete plug or other,'appropriate means. Cleared materials should*
-be disposed of Aite. All nibble and debris created during'dern' olition. should also be removed from th'.6 site.,
Based onsubsurfaoe conditions encountered in the'exploraii6ns, it is our opinion, that temporary slopes
incompetent, undisturbed native soil could be cut at an angle of 'about I H: IV or flatter. Slopes in the existi
in&
fill should be cut not steeper than about I'M, IV. Consistent with conventionalconstiuction practices, the
contractor should, be responsible'for maintaining safe slopes based on conditions present in the excavation.
All local, state, and federal safety rules should be followed whileexcavating slopes and working near.open
cuts. -Pemidnent cut. and fill slopes should be constructed at slopes of 2H:IV or flatter.,.:
Following, clearing, �trippin
g, excavations. to grade, and any required overexcavation,.and before
placement of a ment, s' 'I"
ny'structural fi the exposed,sub&ade under all areas to be occupied by pave oi -
supported slabs, or spread footings should be proof.rolle'd or compacted to a'dense and unyielding condition
with.a loaded dump truckjarge self-propelled vibrating roller, or equivalent. The purpose of this.effort is to
identify possible -loose or soft soil deposits- and to r&offipact the soil exposed during site demolition and

observed by a geotechnical engineer to confirm that design recommendations are met.
FoUND.�TION SETTLEMENT'
Settlement of shallowfoundations depends on both soil bearing piessureand. foundation size, as well
,as the strength and compressibility characteristics of the underlying soil. The'soil response to applied, stresses
caused, by building and other loads is'.expe6ted to be predominately elastic in nature. Most of the settlement
should take place relatively rapidly during construction as loads are, applied.
Our estimates of settlement for shallow foundations are based on'th6 maximum allowable soil bearing
pressures recommended previously. For footings founded on undisturbed native soil or on properly compacted
structural fill placed directly over native soil, 'we estimate a* maximumtotal settlement of about V2 to 3/4- inch,
witli a differential- settlement between adjacent . footings expected to be less than I 1/2inch. The settlement is
expected to be relatively elastic in nature with most of the settlement occurring as the loads are applied.. -
SLAB -ON -GRADE SUPPOkT
New. slabs -on -grade will consist of building floor slabs. and exterior walkways. Undisturbed native
soil or well -compacted, structural fill should provide a stable slab subgrade when prepared as described below,
with the intent of placing concrete shortly after completion of the subgradi6 preparation.
'Proper preparation,of subgrades supporting slabs is needed to reduce,the potential for excessive
concrete cracking or differential s6ttlements., Preparation of subgrade areasin' a manner described in previous
sections of this report should provide 'an adequate ba�e for floor slab support. The subgrade should be proof -
rolled with heavy equipment to identify any soft or unstable zones and to provide a smooth, unyielding surface
for slab support.- Any areas exhibiting significant deflection, pumping, or weaving that cannot be adequately
reworked and/or corripacted'should be oyerexcavated and backfilled with 'appropriately compacted material.
It is recommended- that proof -rolling be observed by a representative of the geotechnical engineer.
-We recommend that interior -floor slabs be underlain by a minimum of 4 inches of compacted, clean,
free -draining sand and gravel with less than 5 percent passing the US, No. 200 sieve, based on a wet sieve
analysis of -that portion passing the No. 4-sieve.' The purpose of this -layer is to provide uniform support for
the slab and to actas a drainage layer. The'drain'age layer should be hydraulicallyconnected to an exterior
footing drain or other appropriate drainage collection system. To reduce the potential for capillary,moisture
to migrate through floor slabs, a continuous impermeable membrane of 6- to 10-mil polyethylene sheeting can.
be installed below the slab. In order to promote A more -uniform curing of the slab and to provide protection
of the vapor membrane during construction, it is advisable to place 2 inches of sand over the membrane. The

sand �hould* be moistened slightly'prio'r to placing slab concrete. Exterior slabs may be supported directly on
undisturbed native soil or properly placed and compacted structural fill, but. for better long-term performance,
it may be advisable to place a layer of clean, durable, well -draining granular material.
FOUNDATION DRAINAGE
The site reconnaissance and field 'explorations were conducted during late s . pring and early summer.
Explicit. signs of poor site drainage were not observed. However, we understand that school staff have reported
wet surface conditions in the winter, particularly in the playfield areas. The 6onsistency-of the undisturbed
native soil coupled with its relatively high percentage of fine material makes it relatively impermeable. The -
existing fill also has a high percentage of fine material. The high percentage of fines in these materials
severely impedes the downward and lateral. migration of water and limits the soil's ability to dis'sip . ate excess
Water.
We recommend that exterior footing drain systems�be constructed around the periffieter of new
"building foundations and adjacentio any subsurface retaining walls. The drains shouldconsist of a minninium
4-inch diameter perforated pipe, surrounded by a minimum 12 inches of filtering media and sloppd'tq carry
water toa suitable collection and discharge system. The filt6ring media may consist of open7graded drain rock
wrapped'by a nonwoven geotextile fabric (such as Mirafi;140N, Synthetic Industries 35 1, or.equivalent) or -
a graded sandand gravel filter. The drainage backfill should contain less thip 3 percent by weight passing the
U.S. No. 200.sieve, based on wet sieve analy�sis -of that portion passing the No. 4 sieve. The invert of the pipe
should be placed at approximately the same'elevation as the bottom of the, wall footing elevation or 12 inches
below adjacent floor slab grade, whichever is deeper, so that water will not accumulate behind walls or seep
through wall or slab concrete.
Retaining wall drainage could consist of a system of prefabricated drainage panels or free -draining
sand and/or gravel placed directly behind. the wall. The sand and/or'grayet should meet the gradation. criteria
described above. Drainage material should be 'placed full -height behind- walls except where the backfill surface
would be exposed to surface water infiltration (i.e. landscaped areas). In these areas, at least 2 ft of fine-
grained soil and a nonwoven gebtextile should be placed over the drainage media near the. surface to seal it
60m, w at,er -infiltration. As discussed irf,the floor slab support section, slabs. should -be u nderlain by a
permeable drainage layer hydraulically connected to An appropriate drainage collection system.
Positive surface gr�dients sh6uldbe provided adjacent to buildings to direct surface water away. from
the, foundation and toward suitable dischar'ge facilities. Roof drainage should not be'introduced into,the
perimeter footing drains, but should be discharged directly to the storm water -collection system -or other,
Appropriate outlet. Pavement and sidewalk areas should be sloped and'drainage gradients maintained to carry

all surface water off ihe site or to the storm water collection system.' Surface water should not be allowed't6
pond and, soak into the ground surface near buildings or paved,areas- during or after constructi6n. Construction
excavations should be sloped to drain to sumps where water from, seepage, rainfall, and 'run'off. fro 'in t-he'-
excavation can be collected and pumped to.a suitable facility.
LATERAL EARTH PRESSURES
The lateral earth pressures that.develop against subsurface building and retaining walls will depend
on the method of backfill emenit, degree of compa�tion,..backfill'slope,'type of backfill material' drainage
'placi
provisions, and the degree to which the wall,can yield laterally during or after placement of backfill. When
the wall is, re§'trained against lateral. movement or tilting, the soil pres�ure exerted is th6'at-rest soil pressure.
Wall restraini"may develop if 'a 'rigid structural network,, is -constructed priorlo backfilling.,pr if the w:all is
inherently stiff. If. the wall is allowed to rotate, or yield so, the top of -the Wall- moves an amount equal'to or
greater than about 0.00 1 ti m'es its, height, -the soil pressure -will be the active soil pressure.
We* recommend that" yielding'wallswith: level backfillunder drained conditions be designed for,ah
equivalent fluid density of 35-p6unds per cubic. ft (pcf) for active soil- conditions. N6nyielding walls bnd-er
drained conditions should be designed forhn equivalientfluid-denisity of 55 pcf for,at-rest conditions. , Design
-of subsurface.walls� should include appropriate, lateral pressures caused by. any adjacent vertical surcharge
loads. For uniform surcharge pres§.ur6s, a'tinif6rmly distributed lateral.pressuire equal to 3.5 percent and 50
percent of the'vertical surcharge pressure 'should, be added to the lateral.soil pressures for. yielding and
restrained walls, respectively.
Lateral loads may be,r6sisied by passive earth pressures develope# against the s,ide of the foundation.
'For design purposes, the passive resistance of well -compacted. fill placed against the sides of the foundation's
may be considered equivalent to a fluid with a density of 300 pcf. Thi.9value assumes drained conditions that
will prevent did buildup- of h ydro static pressure in'the �omp I acted fill., These values are based on, the
assumption of a horizontal. surface of at least two times the depth of embedment in the direction of movement.
The upper-12 inches 'of passive resistance should be,neglect6d if the soil -is not covered by floor slabs or
pavement. If future plans call- for the r6moval'of the soil providing resistance, then the passive resistance..
should not be considered.
A coefficient of base friction, applied to vertical, dead loads onl ,of 0.30'may be used betweedth6
y
base of the footing and the underlying soil.' A safety factor of 1.5 is included in. the. pa]ssive pressure and base
friction desii values. We do�noi recommend increasing the coefficient 'f.frictioti to resist seismic or-wifid
gn
loads.

ASPHALT PAVEMENT
New pavement sections must be installed.over firm subgrade.'The, top 12 inches of subgrade in cut
areas. and- all fill soil should be 'Compacted to at least 95 percent of the maximum dry density per ASTM
155T Following excavation or filling to establish subgrade elevation, but immediately prior to paving, t I he

areas exhibiting excessive movement, pumping,,or weaving exposed -by this proof -rolling, which cannot be
easily stabilized, should'b6 ovefexcavated and backfilled with granular fill, placed 'and com t'
pac ed as previously
described. It is recommended iliat Proof -rolling be observed by a re resentative of the'geotechnical engineer.
P
Our minimum pavement design recommendations are made assuming -the pavement subgrade will
consist -of well -compacted structural fill. Paving operations should be scheduled for the drier and warmer
summer months. If work is accomplished during wet weather, 'an additional layer of permeable crushed rock
may be required to properly prepare the s6gode. A California Bearing Ratio of 10 percent has been assumed
for the compacted subgrade soil based on our review of site soil conditions and experience at sites with similar
."Soil conditions. For access drives and areas of heavy bus or truck traffic, we recommend a flexible pavement
section of ai least13 inches of asphalt concrete over 7 inches of crushed rock base. In parking lots and areas
limited to automobile and, light truck- traffic only, We recommend, 2 inches of asphalt concrete over 5 inches
of crushed rock base. 'Crushed rock base should be com acted to at least 95 ercen

If possible, heavy construction equipment imposing loads.greater than the normal loads assumed in

areas cannot be avoided, a thickened pavement section design should be incorporated into the project plans.
The thickened pavement areas should be identified as designated equipment routes and heavy construction
-traffic should be' restricted to these designated routes.

Footing stiffness and overall response of the building foundation system are typicallyevaluated using
the.shear modulus, G, and the Po'isson's ratio, V, of the supporting foundation soil. G is'generally a function
of soil type, effective confining pressure, and strain amplitude, while, p is generally a function 'of soil type and
relative density. Based on an estimated shear wave velocity of about 900 ft per second for shallow soil beneath
the foundations, we estimate a maxiinum value for G, G.., of about 3,200 ksf for the. relatively dense and stiff
-native foundation soil and compacted- structural fill placed above that soil. This value i's for very low shear
strain's on the order. of 0.0001 percent.- Str . ong-motion earthquakes can produce I m . fich larger shear,strains
,related to footing ie.spqnse typically ranking from about 0.01 to,0.5 percent. These higher shear strain& will
result in significantly. lower corresponding values. for G. Accordingly, we recommend selecting a value for

DESIGN REVIEW/CONSTRUCTION MONITORING
Landau Associates recommends that a general review of the'earthwork andfoundation portions of the
design drawings and specifications be accomplished by a geotechnical engineer familiar with the project
design. The purpose of the rev,iew'is to verify that the recommendations presented in this report have been
properly. interpreted* and implementedin the -design and specifications.
We recommend that geotechnical construction: monitoring'services be provided. 'All building areas
and footing excavations should be observed by a representative of the geotechnical engineer. Observations
should be conducted after the demolition and removal of existing landscaping, structures, and utilit I ies and
should also be conducted atfooting -excavations, after the reinforcing, steel has been placed and'within 2,4 hours
prior to placing.concrete.
We recommend that a geotechnical field representative be present to obs . erve other excavations, to
monitor fill placement and compactiodactivities, to observe proof -rolling operations, to document that design
subgrade condition's are'obtain'ed beneath build . ing' and paved areas, and to confirm appropriate drainage
material use and placement. We recommend that in -place density testing be performed on fills, backfills, and
finished subgrade surfaces. Conformance testing of, imported ma�teri - als may also be needed to verify
compliance with project specifications and our recommendations.
The purpose of these services would- be to observe compliance with the design concepts,
specifications, and -recommendations of this report, and to simplify design or construction changes in the event
subsurface conditions differ from those anticipated before the start of construction. Landau Associates would
be pleased to provide, these services for you.
