Jim, could you go a couple steps beyond this direction? Could you
and Engineering each identify an individual inspector who is assigned
to this project who will make daily stops at the site to look for and
respond to issues such as dust, mud in the street, construction
equipment and vendors accessing the site through the neighborhood,
etc. This has been so controversial that I believe that we need
identified contact people with the city who have ease of access to
supervisors of the construction crews, knowledge of all the
conditions of approval specifically the restrictions, and direction
to err on the side of enforcement.
This will be a issue consistently throughout construction and I want
us to be on top of it, always ready to respond to council and the
public in a manner that exhibits our control of the situation.
y' I would be happy to meet with you and Greg about this if you wish.
Thanks.

Paul Hunt, was in today and complained about the dust from the
construction at Arbor Hts. Next time an inspector goes out would
you have them address this issue. I have asked Engineering the same.

Here is the info...thanks for taking these
back!!!!!!!!!!!!!!!!!!!!! I!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
FYI, they are watering both 109th and Naeve
Sts three times a day, once at the beginning
of the work day, once at lunch time, and once
before leaving for the evening. They are also
running the water truck around the site every
hour or.two, there's really not a whole lot more
they can be doing. If you think it would be helpful
for you and/or Tom I have the name and phone number
for the project manager out on site. Let me know if
this would be helpful.
anyway, here are the names /numbers of the people that
complained. I didn't call them back yet today but I did
speak with the project manager at lunch time.

Re: Arbor Heights Apartment Complex
Dear Sir or Madam:
I am advised by your sprinkler contractor for the required alarm and monitoring
systems that, in order to issue the sprinkler system, we will require the following:
1. Provide an application and plans for your sprinkler monitoring and alarm
system [OSSC, Section 904.3.1 and 904.3.2]. Provide visual alarms in
accordance with OSSC Section 1109.14.2 and access to alarms in
accordance with OSSC, Section 1109.14.4.

FROM: Jean Heitschmidt, DST
DATE: 23 February 1996
SUBJECT: Building Permits for Arbor Heights
After a quick look at the plans for Arbor Heights Jill and I discovered several discrepancies
between the requirements listed for permit approval of SDR93 -0009 and the applicant's
submittal. To list just a few:
ENGINEERING:
a. Engineering Division to receive 2 sets of sitework plans and 7 sets of approved
plans including itemized cost estimates prepared by a P.E. in addition to the standard
site plans. See condition #2 attached.
b. Engineering Division to receive Assurety Agreement and 100% bond before building
permits can be issued. Condition #20 (attached) also requires review and approval by
the Engineering Division.
c. Street work on the new portion of 109th and the addition of a fire lane/hammerhead
is shown on site plan E1.2, but is missing on the WH Pacific drawing (attached).
d. Street Opening Permits were not addressed in the letter from Dennis Riebe.
e. Our plat, Book 54, Page 38 for Bramble Bend is missing, so I couldn't check to see if
2S1 10 AD -9200 is as represented.
f. Bramble Bend sanitary sewer M.H. #2 doesn't seem to be shown on the sitework plan
as required. In fact the sewer line on 109th and the 'T' to TL9200 is not illustrated.
PLANNING:
g. The parcels listed in Tidemark for the SDR are different than the parcels in the final
order. Also, BUILDING 'N' IS DESIGNED OVER TWO SEPARATE PARCELS! Which
parcel should be primary? There are no conditions to address extinguishment of one
of the parcels. See map attached. If we created the 30+ permits for this project on
the wrong parcel, it would take days to correct.
BUILDING:
h. The applicant refers to a "Commercial Plans Submittal Checklist." That one is for a •
commercial structure only (a shell). We don't have a multi - family checklist.
I. The plans show fire alarm terminal cases, fire horns, security circuits for the fire
alarm system; GTE's equipment; security lighting w /detectors on each building; and
probably lots of stuff we missed. Limited energy and fire suppression permits are
needed. There is a sprinklered control room in the Rec Building too.
j. Should we fax them permit applications for Plumbing, Electrical and Mechanical?
A
Page 2 of 2
Arbor Heights
h. When I last talked to Mike from ? ?'s office, he said the contractor would not
apply for the specialty permits because, " we're going out to bid." Then they forget
to tell us who won the bid and guess what happens. I told them to submit an
application with "out to bid" in the spot for contractor and then we could proceed with
plan review for plumbing, electrical, etc.
I. Permits will take forever to create, so the more we know now, the less time it will take
to update /correct.
j. Is it realistic to believe the SDR conditions will be completed?
k. Will we still hold permits until all conditions are completed?
MISC:
I. Add TIF, SDC's to one permit or distribute on all buildings.
m. Some pages show carports, some show garages. We need to contact them and find
out if they are garages, carports or both?
Call me if you need me to help this weekend.

Dear Applicant:
The Development Services Team recently received building plans for your commercial
project without a sitework permit application. To expedite the plan review process, please
forward a sitework plan (one copy), permit application and payment as soon as possible.
After the sitework plan is received the Plans Examiner will be able to address:
1. Handicap Accessibility
2. Storm and Sanitary Sewers (building laterals)
3. Fire Line, Water Line, Private Water Mains, Water Meter Location and Size
4. Site Erosion
5. Site Detention (grading, retaining structures)
6. Utility Location
7. Private Streets
8. Landscaping (per conditions of land use resolution)
Overall, the sitework plan determines many of your development's features. Before the
building plans are approved the sitework plan is distributed to Tualatin Valley Fire and
Rescue, United Sewerage Agency, and the City's Water, Engineering, Planning and
Building Departments for comments and corrections. This preliminary coordination takes
extra effort, but will result in fewer revisions and quicker final approvals.
Thanks for your cooperation. If you have any questions or concerns, please feel free to
contact me at 503 - 639 -4171, extension 322. If you reach my voice mail, please leave a
message or transfer to the Development Services Team at extension 304.

Dear David, .
I have reviewed the City of Tigard Site Permit review; items regarding accessibility, as you requested. The
following is my analysis of thcsc correction requests, and what I think needs to be done to the drawings to
satisfy those concerns.
Regarding ACCESSIBILITY item #I:
•
These are revisions that nccd to occur to your drawings in the locations referenced. Please:see my sheet A1.2
which shows the plan view of the van - accessible parka stall, located in front of the recreation building.
We should add this plan view to your drawings.
Regarding ACCESSIBILITY item #2: . .
The handrail shown on your detail needs revision. The handrail shows the required horizontal extension
required at the top of the stairs. Add a dimension showfing•that this is 12" beyond the nosing of the first riser. '
Revise this detail at the toe of the stairs to show a horizontal extension that measures 12" + I tread. depth_ /
This extension needs to start at the nosing of the first riser from the bottom. Dimension this minimum
dimension. Add to the specification of this handrail that the required 1 1/2" diameter is OD.
Regarding ACCESSIBILITY item #3: •
We need to provide and accessible route, as defined inf, OSSC to the locations noted in the review letter_ As
we discussed on the telephone, some additional curb etas need to be added. As we discussed, the accessible .
route needs to extend to the site facilities on site, which with the additional curb cuts, will be provided.
I
We need to extend the accessible route to the propert lines which will tie into the City sidewalk on 109th
Street. You have shown that the required curb cuts a provided on this street at the required locations.
There are no public transportation stops on our site. Therefore, the public transportation stops that we need
to provide access to are on the City streets. I believe that since we have provided the necessary curb cuts from
out site, across our entry roads, and the city street intlersections, we have satisfied the requirements of the
code. The balance of the travel route is on city stye I ts and I am sure that the city has • provided for this
continuation in their design and construction of these affected city streets.
The sidewalk slopes in our site, and on the city streets, O re acceptable. We have designed the site roadway and
pedestrian access system to the minimum slopes possiblg given the sloping nature of the site. We have adhered
to the city requirements for maximum slopes allowed, a directed by the fire department access. OSSC Section
3103 b. 4 C is the section that mandates the slope requirements of walks. Exception 1 applies to our site in
those areas where site infeasibility precludes a running slope of 1:20. In these locations, which arc minimal,
