As you may be aware, our client, White Star Development, entered into a Developer's Extension
Agreement with Soos Creek Sewer and Water District to provide water service to the Talbot
Ridge Development. The reason that Soos Creek is serving this area, is that the elevation of the
development is too high for Renton's water system to serve. Therefore the city deferred to Soos
Creek to provide service. In late December 1998, the engineer for the District, Mr. John Block,
of Roth/Hill Engineers received a letter from your Fire Marshall's office signed by Mr. Corey
Thomas, which rejected the water system design because it was not a looped system.
Unfortunately, Triad Associates did not become aware of this until mid April 1999. In
discussions with the District and with Roth/Hill Engineers, they have indicated that Soos Creek
endeavors to provide a looped system. However, in instances when there are 20 lots or fewer,
and providing a looped system is' problematic, they do not require looping the system. The
design as presented to the City of Renton meets the requirements of the Soos Creek Water and
Sewer District.
The pre-construction conference for this development was held at the City of Renton on May 13,
1999. In that meeting Corey Thomas recommended providing a redundant, eight-inch water
main with a separation of 10 feet, which reconnects to the water main on 102nd Avenue. In my
opinion, this proposed solution is flawed. The redundant system adds a cost of over $46,000 to
the project. Since the entire water system in the northern portion of 102nd Avenue is already a
dead end, we see no benefit to providing a looped system back to a dead end line.
We are hereby requesting your reconsideration of the looped water system requirement. You
may be aware that the two parcels of land to the south of Talbot Ridge are slated for
development in the near future. The developer is negotiating an emergency secondary access
route for that development which would then satisfy the requirement for looping the water
system. Our best estimate on the timing of that development is approximately two and one half
years.

It is my understanding that Mr. Ron Speer, general manager for the Soos Creek Water and Sewer
District is planning to either discuss this issue or meet with the appropriate personnel at the City
of Renton to come to an agreement on this issue. I highly encourage us to meet and resolve this
as quickly as possible. Thank you for your consideration. I may be reached at(425) 821-8448.

Re: Proposed Land Use Action on Campen Property Adjacent to Talbot Ridge
Dear Mr.Lumbert:
Ross Case has asked me to contact you for the purpose of informing you of our plans to develop property
located adjacent to the Talbot Ridge project. I understand there are some water issues he is being faced
with that may be avoided if the city of Renton has some assurances that the property to the south will be
developed in the foreseeable future.
Schneider Homes,Inc. is under contract to purchase Lila Campen's twenty acres located on the east side of
Talbot Rd. S. While we are currently working on a proposal to create 152 condo/townhouse units on the
ten acres located at the toe of the slope,no application has been made to develop the approximately 7 acres
located at the top of the hill. We have every intention to submit a development application for the balance
of the property once we have the Site Plan Approval for the lower portion in hand.
Since we have a July 8, 1999 date before the Community Planning Committee for the purpose of
addressing our appeal of the Hearing Examiner's decision,I can assure you that no applications will come
in before that time. But, in the event the Council overturns the Examiner's decision,we will most likely
apply for development permits on the balance of the property before the end of 1999.
If you have any questions,please feel free to call me at(206)248-2471.

MEMORANDUM
DATE: July 17, 1998
TO: Fred Kaufman,Hearing Examiner
FROM: Jennifer Toth Henning 00
SUBJECT: Talbot Ridge Preliminary Plat(File No. LUA-97-087,PP,CU-H,V)
The applicant has submitted a revised preliminary plat map which modifies the previous submittal in
January of this year, and which addresses Conditions No. 1 from the Hearing Examiner's Decision
and Recommendation (dated December 4, 1997). Staff has reviewed the proposed plat drawing for
compliance with the recommended conditions of plat approval and the development standards of the
R-8 Zone. A summary of that analysis follows:
R-8 Zone. The Hearing Examiner's Decision and Recommendation approves the Conditional Use
Permit and Variance, and recommends approval of the Preliminary Plat for 16 to 18 lots, subject to
conditions. The applicant submitted a revised plan in January that showed 17 lots and a temporary
cul-de-sac on an easement that would be included on a tract of land (Tract C). The applicant
proposed creating a tract for the turnaround, that could later be short platted to create an additional
buildable lot, when the road was extended off-site. Separate tracts (Tracts A and B)were shown on
the January 1998 submittal for Native Growth Protection Easement.
The revised Talbot Ridge Preliminary Plat is 18 residential lots, each suitable for the construction of
one detached single family residential home. The former Tract C is now shown as new Lot No. 4, and
the temporary cul-de-sac turnaround has been moved off-site to the abutting property on the south.
Burnett Avenue South would be extended to tie into the abutting property for the turnaround, until
such time that Burnett is extended through the property to the south. The applicant has provided a
draft easement agreement between the property owners for the granting of the easement.
The proposal for 18 lots is consistent with the Hearing Examiner's Decision and Recommendation and
also with the primary permitted uses in the R-8 Zone.
Tracts. One tract is delineated on the revised preliminary plat mat. Tracts A represents the steep
slope area on the west portion of the site. This area shown is the Native Growth Protection Easement
for the site. Previously shown Tracts B and C have been eliminated. Tract B was combined with
Tract A and Tract C was converted to a residential lot.
Based on discussions with the City Attorney, staff is recommending that the applicant that a covenant
be recorded on the property which states that the Homeowner's Association be responsible for
maintaining the Native Growth Protection Easement and paying taxes on the property.
Development Standards. The preliminary plat drawing indicates lot size, width and depth
dimensions, and setbacks. Each of the proposed lots meets the minimum lot size, width and depth
\\TS_SERVER\SYS2:\COMMON\-H:\DIVISION.S\DEVELOP.SER\DEV&PLAN.INGVTH\TALRDHXDOC\sj
Page 2
requirements. Lots No. 5 and 7 are pipestem lots that meet the minimum size, width, depth and
setback requirements exclusive of the pipestem portion of the lot. Lot No. 11 has a front width
dimension of 35 feet, which technically qualifies the parcel as a pipestem lot. Lot No. 11 would still
have sufficient lot area when the pipestem portion of the parcel is eliminated from the calculation. Lot
11, could also be considered to be located on a turning circle of a road, and therefore, the 35-foot
width is acceptable as is.
Density. The proposal for 18 residential parcels complies with the density range permitted in the R-8
Zone. A maximum of 18 residential parcels would be permitted given the current configuration which
includes a temporary turnaround located off-site. The density achieved under the 18-lot configuration
has been calculated at 7.75 dwelling units per acre. This is within the permitted range of 5.0 to 8.0
du/ac as permitted in the R 8 Zone.
Access. Each of the proposed residential building lots would be accessed form the new public street,
South 47th/Burnett Avenue South. Lots 5 and 7 would access via a 20-foot wide pipestems, 80 and
100 feet long respectively. Lots No. 11, 12, and 13 would utilize a 26-foot wide private street for
access from the new public streets (consistent with Code Section 4-34-5, Street Improvements).
I belive this proposal addresses all of your concerns and meets the conditions of the Decision and
Recommendation of December 4, 1997. Please feel free to contact me if you have any questions or
comments regarding this project. I can be reached at 430-7286.

Re: Talbot Ridge Preliminary Plat
LUA97-087,PP,,CU-H,V
Dear Jennifer:
This office has reviewed the latest submittals from the applicant and staff. It appears that most of the
pre-conditions.have been satisfied regarding lot and road dimensions. . .
There is still a concern over creating Tract C. This would provide a separate tract that would be used to
accommodate the cul-de-sac bulb. Since there is no time-frame in place for the expansion or connection
of the road system to create a through street,the tract could be in existence for a long period of time.
That raises the possibility that the portions of the tract not occupied by road will slip into a non-
maintained appearance..If ownership were to remain with the applicant;.there would be no way to
burden the remaining homeowners with the costs or responsibilities to maintain the excess property.
Therefore, it should be added to Proposed Lot 3,remaining subject to the easement for the cul-de-sac
bulb. If the road is eventually extended and the cul-de-sac abandoned,then that portion of enlarged Lot
3 can be segregated according to the then existing zoning standards. Therefore,Tract C should be
eliminated and made part of Proposed Lot 3.
There does not appear to be any reason to complicate the plat or legal descriptions by creating a Tract B,
which appears to be part of and subject to the same Native Growth Protection Easement standards as the
much larger Tract A._It is merely separated by an easement. It should be eliminated and incorporated
into Tract A. The homeowners shall be clearly responsible for the maintenance of the Native Growth
Protection Easement and it shall not be sold or developed other than for the currently proposed utility
. easement.
It appears that the discrepancy in the legal description has been rectified.
With the submission of a Plat map incorporating Tract C into Lot 3 and the consolidation of the Native
Growth area into.one tract,the plat can be submitted to the City Council.
If this office can be of further,assistance,please feel free to write.
Sincerely,
•

DATE: January 27, 1998
r
TO: Fred Kaufman,Hearing Examiner
FROM: Jennifer Toth Henning d
SUBJECT: Talbot Ridge Preliminary Plat--LUA-97-097,PP,CU-H,V
The applicant for the Talbot Ridge Preliminary Plat, Triad Associates, has resubmitted the
preliminary plat map in compliance with Condition No. 1 of the Hearing Examiner's Decision and
Recommendation (dated December 4, 1997). Staff have reviewed the proposed plat for compliance
with the recommended conditions of plat approval and the development standards of the R-8 Zone. A
summary of that analysis follows.
R-8 Zone. The revised Talbot Ridge Preliminary Plat is shown with 17 residential lots, suitable for
the construction of detached single family residential homes. The proposed use is consistent with
primary permitted uses in the R 8 Zone.
Tracts. Three tracts are delineated on the plat map. Tracts A and B include the steep slope area on
the western half of the site, and are shown as being reserved as Native Growth Protection Easements
(NGPE). A 15-foot wide utility easement for stormwater and sanitary sewer lines separates the two
NGPE tracts. Based on recent discussions with the City Attorney, staff will recommend to the
applicant that only one NGPE tract be established and recorded for the steep slope area. The utility
easement will be established within that NGPE. Furthermore, the City Attorney has advised that a
covenant be recorded which states that the Homeowner's Association be responsible for maintaining
the NGPE and paying taxes on the property.
The applicant shows Tract C for future development, and intends to create an additional residential lot
in the future when Burnett Avenue South is extended off-site to the south, and the temporary cul-de-
sac is vacated. A future short plat would be needed to create the additional residential lot at the time
that the temporary turnaround is vacated. Application for the short plat could be made consistent with
state subdivision law.
Development Standards. The preliminary plat drawing indicates lot size, width and depth
dimensions,and setbacks. Each of the proposed lots (including Tract C)meets the minimum lot width
and depth requirements. In addition each of the lots (Nos. 9, 10, and 13) lying around the cul-de-sac
exceed the 4,500 square foot minimum lot size requirement exclusive of the easement and consistent
with Condition No. 2. Lots No. 5 and 6 are pipestem lots and meet the minimum size, width, depth
and setback requirements exclusive of the pipestem portion of the lot. Lot No. 10 would also be
considered to be a pipestem lot, since it does not meet the minimum lot frontage requirements.
However, it too meets the minimum size requirement of 4,500 square feet after deducting the area for
the temporary turnaround and the pipestem portion of the parcel.

Density. The proposal for 17 residential parcels complies with the density range permitted in the R-8
Zone. .A maximum of 17 residential parcels would be permitted given the current configuration which
includes a temporary turn-around. Once the turnaround is vacated (assuming extension of the public
street to the south), the additional land area available could accommodate one more lot and still be
within the density range of 5.0 du/ac minimum and 8.0 du/ac maximum. With 17 parcels the density
would be 7.75 du/ac. When the additional right-of-way is vacated, and if another lot was approved
via a short plat,the density would also be 7.75 du/acre.
Access. Each of the proposed residential building lots would be accessed from the new public street,
South 47thBurnett Avenue South. Lots No. 5 and 6 would access via a pipestem that would be 20
feet wide and 80 to 100 feet in length. (These distances are within the regulations governing pipestem
lots as stated in Code Section 9-12-19:D.) Lots No. 12 and 13 would access via a joint-use driveway
located on a permanent 26-foot wide access and utility easement consistent with Code Section 4-14
(Parking and Loading Ordinance). The access/utility easement would be partially located on Lot Nos.
10, 11, 12 and 13.

SUBJECT: Talbot Ridge Preliminary Plat(File No. LUA-97-087,PP,CU-
H,V,ECF)
You have requested clarification of two issues pertaining to the above-referenced preliminary plat.
The first has to do with errors on the legal description shown on the previously submitted plat
drawing. Your second concern was with regard to ownership of Tract C.
1. The attached preliminary plat drawing has been revised by the applicant to address the
concerns regarding errors in the legal description. The legal has been revised and approved as
acceptable by Bob MacOnie,Property Services. Written documentation of that approval will
be forwarded to your office separately.
2. According to Brian Johnson of Triad Engineers, the owner, Jim O'Donnell intends to retain
ownership of Tract C until such time that application is made to further sub-divide the parcel.
'That application could not be made until the public street is extended, and the restrictions for
use of Tract C for temporary turn-around are removed.
Alternatively, Tract C could be incorporated into either Lot No. 3 or Lot No. 4, and the owner
of either Lot 3 or 4 could make application for the future subdivision.
Should you have any other questions,please contact me at Extension 6186.

MEMORANDUM

TO: Fred Kaufman,Hearing Examiner
FROM: Jennifer Toth Henning C1
SUBJECT: Talbot Ridge Preliminary Plat--LUA-97-097,PP,CU-H,V
The applicant for the Talbot Ridge Preliminary Plat, Triad Associates, has resubmitted the
preliminary plat map in compliance with Condition No. 1 of the Hearing Examiner's Decision and
Recommendation (dated December 4, 1997). Staff have reviewed the proposed plat for compliance
with the recommended conditions of plat approval and the development standards of the R-8 Zone. A
summary of that analysis follows.
R-8 Zone. The revised Talbot Ridge Preliminary Plat is shown with 17 residential lots, suitable for
the construction of detached single family residential homes. The proposed use is consistent with
primary permitted uses in the R-8 Zone.
Tracts. Three tracts are delineated on the plat map. Tracts A and B include the steep slope area on
the western half of the site, and are shown as being reserved as Native Growth Protection Easements
(NGPE). A 15-foot wide utility easement for stormwater and sanitary sewer lines separates the two
NGPE tracts. Based on recent discussions with the City Attorney, staff will recommend to the
applicant that only one NGPE tract be established and recorded for the steep slope area. The utility
easement will be established within that NGPE. Furthermore, the City Attorney has advised that a
covenant be recorded which states that the Homeowner's Association be responsible for maintaining
the NGPE and paying taxes on the property.
The applicant shows Tract C for future development, and intends to create an additional residential lot
in the future when Burnett Avenue South is extended off-site to the south, and the temporary cul-de-
sac is vacated. A future short plat would be needed to create the additional residential lot at the time
that the temporary turnaround is vacated. Application for the short plat could be made consistent with
state subdivision law.
Development Standards. The preliminary plat drawing indicates lot size, width and depth
dimensions, and setbacks. Each of the proposed lots (including Tract C)meets the minimum lot width
and depth requirements. In addition each of the lots (Nos. 9, 10, and 13) lying around the cul-de-sac
exceed the 4,500 square foot minimum lot size requirement exclusive of the easement and consistent
with Condition No. 2. Lots No. 5 and 6 are pipestem lots and meet the minimum size, width, depth
and setback requirements exclusive of the pipestem portion of the lot. Lot No. 10 would also be
considered to be a pipestem lot, since it does not meet the minimum lot frontage requirements.
However, it too meets the minimum size requirement of 4,500 square feet after deducting the area for
the temporary turnaround and the pipestem portion of the parcel.

Density. The proposal for 17 residential parcels complies with the density range permitted in the R 8
Zone. A maximum of 17 residential parcels would be permitted given the current configuration which
includes a temporary turn-around. Once the turnaround is vacated (assuming extension of the public
street to the south), the additional land area available could accommodate one more lot and still be
within the density range of 5.0 du/ac minimum and 8.0 du/ac maximum. With 17 parcels the density
would be 7.75 du/ac. When the additional right-of-way is vacated, and if another lot was approved
via a short plat,the density would also be 7.75 du/acre.
Access. Each of the proposed residential building lots would be accessed from the new public street,
South 47thBurnett Avenue South. Lots No. 5 and 6 would access via a pipestem that would be 20
feet wide and 80 to 100 feet in length. (These distances are within the regulations governing pipestem
lots as stated in Code Section 9-12-19:D.) Lots No. 12 and 13 would access via a joint-use driveway
located on a permanent 26-foot wide access and utility easement consistent with Code Section 4-14
(Parking and Loading Ordinance). The access/utility easement would be partially located on Lot Nos.
10, 11, 12 and 13.

RE: Talbot Ridge BUILDING
DIVISION
Triad Job No. 97-006
Dear Ms. Henning:
In accordance with the Hearing Examiner's decision, dated December 4, 1997, we provide the
following responses to each of the ten conditions addressed in the Hearing Examiners report:
Condition No. 1
The preliminary plat map demonstrating the appropriate aspects of Exhibits 7 and 8 shall be
resubmitted for review by staff who shall forward said plat and written documentation indicating
that each lot meets all City standards within sixty (60) days of publication. If such a plat and
written documentation is not submitted in a timely fashion, the matter will be reopened for
additional public hearing.
The preliminary plat has been modified to include all appropriate aspects of
Exhibits 7 and 8. The revised plat depicts all lots meeting all the required minimum
standards for the City's R 8 zone. Each lot within this plat will have a minimum lot
size of 4,500 square feet. Also, all lots will have the required 50-foot minimum lot
width and 65 feet of lot depth. Each lot will provide a minimum of 15-foot front
yard setbacks, 20-foot rear setbacks, and 5-foot side yard setbacks. Tract C, if
developed, would not meet the setback criteria for the City of Renton due to the
temporary turn-around. Therefore, Tract C is considered a Future Development
Tract for this preliminary plat. As a result, until Burnett Avenue South extends
through to the south and the cul-de-sac can be replaced, Tract C will not be built
upon at this time. Also, as required in the above condition, the applicant has until
February 2nd (60 days from December 4th) in which to resubmit the revised plat.
Therefore, the applicant has resubmitted the plat in a timely matter according to the
Hearing Examiner's conditions.
Condition No. 2
All lots shall have sufficient lot area exclusive of any easement. That is, all lots lying around the
cul-de-sac shall contain 4,500 square feet exclusive of any easement property.
As shown on the revised preliminary plat, all developed lots have a minimum area of
4,500 square feet exclusive of any easements.

Condition No. 3
All public rights-of-way within the site shall be developed to the City's 50 (fifty)foot roadway
standards. The cul-de-sac shall meet all turning radii standards.
The preliminary plat has been revised and depicts a 50-foot right-of-way and a
turning radius of 55 feet which is in accordance with the City of Renton road
standards.
Condition No. 4
The applicant shall submit a tree planting plan showing a minimum of two (2) street trees for
each lot, although the distribution may be altered as determined by the City. The applicant shall
post a bond to assure compliance wit this condition. The City shall be responsible for planting
the trees.
The applicant will comply with the Hearing Examiner's decision and submit a tree
planting plan which will show a minimum of two trees for each lot, or a number to
be later determined by the City.
Condition No. 5
All land clearing both in the plat and particularly along the steep slopes shall be as limited as
possible. In the steep slopes all clearing shall be limited as much as practical to the immediate
vicinity of the two utility lines.
All clearing within the slope area will be minimal, limited to the placement and
maintenance of the storm sewer lines only.
Condition No. 6
The applicant is required to comply with the mitigation measures which were required by the
ERC prior to the issuance of a construction or building permit.
The applicant will comply with all mitigation measures required by the ERC prior
to the issuance of a construction or building permits.
Condition No. 7
The applicant shall draft and record a maintenance agreement or establish a homeowner's
association for the maintenance of all common plat improvements (storm water detention vault,
utility easements, access easements). A draft of the document shall be submitted to the City for
review and approval by the City Attorney prior to the recording of the plat.
The applicant will establish a homeowners association for the maintenance of Talbot
Ridge. The documents for the homeowners association will be submitted to the City
for review prior to the recording of the plat.

Condition No. 8
The applicant shall define and record a Native Growth Protection Easement on the face of the '
plat for the steep slope areas west of the storm water detention vault. The applicant shall adhere
to the City code requirements for such areas.
The plat has been revised to include an NGPE for the sloped areas on the western
portion of the site. The plan depicts two separate NGPE areas, separated by the
storm sewer utility easement.
Condition No. 9
The access tract shown for any lots shall be eliminated and that area incorporated into one of
the lots as a pipe stem, with an access easement for the other lot.
The revised preliminary plat drawing eliminates the access tract which was
associated with the original preliminary plat.
Condition No. 10
The applicant shall be required to install slope stabilization devices as recommended by the
applicant's engineer or geotechnical consultant.
The applicant will install slope stabilization devices recommended by the
engineering firm, Triad Associates, or the geotechnical consultant, Associated Earth
Sciences Inc.

SUBJECT: Talbot Ridge Preliminary Plat
The Technical Services Section of the Planning/Building/Public Works Department reviews but does
not provide legal descriptions for private development projects. In September of last year, I reviewed
some of the initial submittal materials for the subject project. As part of that review, I checked the
legal description included with the Master Application, against descriptions contained in the King
County tax rolls and a title report submitted to the city. All these legal descriptions were consistent
except for a missing word in the title report legal, which was correctly included in the others.
A second and more thorough review of the legal description for this project initiated by the receipt of
your request has revealed that all the legal descriptions cited above contains serious flaws. I have
contacted the title company and the surveyor for this project and requested that they make the
necessary corrections to the legal description for this project.

Re: Request for Clarification/Reconsideration regarding
Talbot Ridge Preliminary Plat,File No. LUA97-097,PP, CU-H,V
Dear Mr. Zimmerman:
I have reviewed your requests for clarification and reconsideration in the above matter.
Condition No. 1
As you might expect,the date that the decision was issued is the date of publication mentioned in
Condition No. 1.
Condition No. 2
Condition No. 2 is not intended to exclude the normal utility easements for water, sewer or
private gas, electric,phone or cable TV lines. It was intended to refer to access easements and
the proposed cul-de-sac.
As you might expect,when an application is as sketchy as this one(with changes submitted
during the public hearing),there,are few concrete details upon which to base a decision,requiring
instead the necessarily vague attempts to define what is not accurately represented in any of the
submissions or exhibits. This lack of both detail and staff review of the late submissions by the
applicant is what gives rise to the Condition No..1 where this office needs the assurance that the
plat actually does meet code requirements.
Condition No. 3
•
The plans were submitted with the larger road dimensions and those were the plans reviewed.
The changes should have been made prior to the public hearing in order for them to have been
considered. Like other aspects of this application,too much was left for conjecture or altered
after staff review,making some aspects of review quite problematic. This is not to say that
modifications after staffs recommendations should be out of the ordinary;but some aspects of
this plat were clearly unacceptable and should have been refined prior to the public hearing.
Condition No. 4
This office adopted the staff recommendation in regards to the number and general arrangement
of the street trees. This office will modify the decision to accept any legal method that assures
200 Mill Avenue South -Renton; Washington 98055 - (206)235-2593
This paper contains 50%recycled material,20%post consumer
that the trees are bonded and installation accomplished. The condition requiring the planting was
to insure that the City act on the bond or other legal guarantee as it would any other bonded
obligation, either contracting out the installation of the improvements as they would street
lighting or similar improvements, or making sure the work is completed.
This office hopes this letter appropriately addresses your concerns regarding this application.

C .

MEMORANDUM
DATE: December 17, 1997
TO: Fred Kaufman,Hearing Examiner
FROM: Gregg Zimmerman 5
SUBJECT: Talbot Ridge Preliminary Plat(LUA-97-087,PP,CU-H,V) --Request
for Clarification/Reconsideration
I have read your decision and recommendation of December 4, 1997 for the proposed Talbot Road
Preliminary Plat. Condition No. 1 states that the preliminary plat map shall be resubmitted for review
by staff "within sixty (60) days of publication." It appears that the publication referenced is the date
of the Hearing Examiner's decision, however, it could be interpreted differently. Please clarify this
condition.
Condition No. 2 states that: "All lots shall have sufficient lot area exclusive of any easement. That
is, all lots lying around the cul-de-sac shall contain 4,500 s.f. exclusive of any easement property."
This condition requires additional clarification. Does the condition pertain to "any" easement
including franchise utilities, City systems, access easements, drainage features, and the like? Or, was
the intent of the condition only for the access easement associated with the proposed cul-de-sac?
Condition No. 3 states that: "All public rights-of-way within the site shall be developed to the City's
50 (fifty) foot roadway standards. The cul-de-sac shall meet all turning radii standards." City Code
Section 4-34-11:D allows a reduction of required right-of-way by the Department Administrator for
new residential access streets within a subdivision "to forty-two feet (42') when the extra area from
the reduction is used for the creation of an additional lot(s) which could not be platted without the
reduction; or when the platting with the required right-of-way width results in the creation of lots with
less than one hundred feet (100) in depth. The Department may require additional easements be
provided for the franchise utilities outside of the dedicated right-of-way when such a right-of-way
reduction is approved. In no case shall a reduction in the required right-of-way be approved unless it
is shown that there will be no detrimental effect on the public health, safety or welfare if the right-of-
way is reduced,and that the full right-of-way width is not needed for current or future development."
With a reduced right-of-way width of 42-feet, the resulting travel lane is 32 feet, the same width of
travel lane as would occur with a 50-foot-wide right--of-way. I understand that the Fire Prevention
Bureau was concerned about adequate roadway width, turning radii, and turnarounds. Please clarify
whether you would permit the applicant to apply for a reduced right-of-way per Code Section 4-34-
11:D.
Condition No. 4 requires the applicant to submit a tree planting plan showing a minimum of two (2)
street trees for each lot, with the possibility of the distribution being altered as determined by the City.
The requirement would result in 32 to 38 trees being planted in association with the plat. Planting of
trees on the individual lots, or in the right-of-way adjacent to the lots would not be practical, since
many of the new lots have narrow street frontage,frontage on an access easement, or driveways taking
December 17, 1997
Page 2
up much of the street frontage. The preference of the Planning/Building/Public Works Department
(PB/PW) is to require the planting of the required trees in the right-of-way for the new public street
(South 47th Street). The trees could be installed along with other street improvements and prior to the
recording of the plat. Therefore, no surety device or bond would be necessary. We rarely bond for
required landscaping, unless a deferral is granted, and I would not support it for this project. In
addition,I strongly yet respectfully disagree with the second portion of the condition requiring the City
to plant the trees mitigating impacts of private developmnet. We do not have the personnel to
accomplish this, and it would set a precedent for other plats,that is not supported by this Department.
Again, if the street trees were installed by the applicant/developer in conjunction with required street
improvements,this could be accomplished in a timely manner, and prior to recording of the plat.
In summary, I am requesting clarification of Conditions No. 1, 2, and 3, and reconsideration of
Condition No. 4. Please do not hesitate to contact me if you have questions regarding this
correspondence.

to thoroughly review the changes. The presentation was made on the application submitted as well as the
alternate layout.
The presentation of the staff report was given by JENNIFER HENNING,Project Manager, Development
Services, City of Renton, 200 Mill Avenue South, Renton, Washington 98055. This is an application not only
for a preliminary plat, but for a conditional use permit and a variance in order to build site utilities. This site is
4.55 acres in size,with 2.7 acres being proposed for the subdivision. This property is located east of Talbot
Road and west of 102nd Avenue SE,which is a street in King County, in the Talbot Hill portion of the City.
There is split zoning on the site. The R-1 zone,which is a low density zone, encompasses a steep slope area on
the western portion. The eastern portion of the site which is to be developed is zoned R-8 and is in the
residential single family Comprehensive Plan(CP)designation.
This parcel is currently landlocked and in order to develop the parcel the applicant would have to extend an
existing street, 102nd Avenue SE, about 200 feet to the north which would end at the point where the City of
Renton and King County boundaries meet. A new street, South 47th Street,would be extended to the west
from 102nd Avenue SE into the site. The property the new street would be located on is currently owned by the
State of Washington Department of Transportation and they are willing to deed over the right of way needed
for this street.
This site has steep slopes that occur on the western portion that range from 25 to 70 percent, and is designated
as a green belt. The eastern portion of the site is flatter ranging from about 5 to 25 percent slopes. There is
extensive vegetation on the site. Applicant has provided geotechnical reports to address the steep slope issues
where the utilities would be constructed, as well as whether or not the homes that were proposed on the western
portion of the developable area would require any special foundations or setbacks and such. The conclusion of
the report was that conventional engineering would suffice.
The new street would be extended into the plat and S 47th Street would end in a cul-de-sac to serve the new 19-
lot plat. There is also a proposal to access some of the lots through a private street system. Lots 1, 2, 3,4, 5
and 6 would be on a private easement from S 47th Street to the south. There would be a driveway access
easement that would serve Lots 9 and 10 in the southwest corner. Lots 8 and 13, as well as Lots 9 or 10 would
be pipestem lots. The other lots, 7, 8, 9, 10, 11, 12, 13, 14, and 15,meet the minimum radius of 35 feet for
location on the cul-de-sac.
This site is zoned R-1 on the west and R-8 on the east. There is a proposal to put a storm water detention vault
at the top of the slope, still within the R-8 area. The proposal includes the extension of utility systems,waste
water and storm water to the southwest corner of the site where there is an existing stub at the Springbrook
Condominiums. Water is being provided by Soos Creek Water District. In order to build S 47th Street from
102nd,there is a drainage swale to be crossed. Because of its size it does not require any special mitigation, but
the applicant is proposing to revegetate the disturbed areas with native and riparian vegetation.
The Environmental Review Committee(ERC)heard this proposal on October 21, 1997. They issued a
Determination of Non-Significance- Mitigated(DNS-M)with six mitigation measures. The applicant was
required to provide additional geotechnical information to determine whether or not the homes that were being
proposed would require special engineering or setbacks. They were required to provide additional detention of
storm water through the 100 year storm event. They will be required to pay the appropriate transportation,

parks and fire mitigation fees, and also to revise their construction mitigation plan to restrict construction-
related traffic to the off-peak hours between 8:30 a.m. and 3:30 p.m.
There is no sewer available in this portion of King County. The only viable choice is to go downslope and tie
into the City system at Springbrook. When the Springbrook project was approved, it was intended that
properties to the east would tie into the system at this location. The City zoned this area for single family
residential lots at a density of up to 8 units to the acre,minimum lot size of 4,500 square feet. The community
needs to absorb additional growth per the mandates of the Growth Management Act and the only viable way to
do that is to tie into the existing utility systems down slope.
In order to build the storm water and waste water lines that would connect to the stubs in the Springbrook
Condominium area in the southwest corner of the site,the applicant has proposed a 20 foot wide utility corridor
through the steep slope designated greenbelt area. In order to do that they need to be granted a CUP. There
would be minimal clearing of vegetation. The applicant proposed to install both the waste water and the storm
water line on the surface, but the State Department of Ecology does not permit sanitary sewer systems to be laid
on top of the ground. In this instance the storm water line would be on top of the ground,the waste water line
would be buried. The actual excavation width would be about 6 feet. The remainder of the greenbelt area
would be undisturbed. Staff is recommending that the remainder of the greenbelt area be placed in a native
growth protection easement that would be recorded.
Development of the utility lines to serve this single family plat would be compatible with the existing and
proposed residential scale of the area. There would be minimal disturbance of the slope to construct the utility
systems. The applicant is proposing to place hill-holders or other slope stabilizing mechanisms through the
slope that would ensure the stability of the line. Vegetation would need to be managed over time so that
maintenance could occur, but undergrowth could re-grow in a particular area. The entire corridor would not
have to be clear at all times.
Staff is recommending approval of the CUP with a condition associated with both the CUP and variance that
the applicant be required to install slope stabilization devices recommended by their engineer.
A variance is needed in order to manage and clear the vegetation in this steep slope area. The clearing which
would occur for the utility lines would tie into the existing sewer stub to the west. There are no other gravity
fed sewer system options existing for this site. The proposed hill holders would help ensure that this project
would not be detrimental to the hillside and it would minimize the impacts to the slope and the greenbelt. All
clearing activities would need to be accomplished in accordance with City codes and policies.
Regarding preliminary plat criteria,this is a proposal for 19 lots and it is within the required density. In this
zone and CP designation, lots are permitted as small as 4,500 square feet. In this proposal the smallest lot size
is 4,500 and the largest lot is 5,642 square feet. These are smaller than the existing lots in the area, but they are
compatible with the R-8 designation. The R-8 zone provides for minimum densities of 5 units to the acre and
maximum of 8 units to the acre. The latest calculation takes into account the additional area zoned R-8 to the
west of the site. The 19 lot proposal would result in a density of 7.68 dwelling units per acre. The lots all meet
the minimum size, shape and orientation of the lots with the exception of the pipe stem lots. Because there are
private street approaches for Lots 1 through 6, staff looks at how these lots lay out and the lot actually goes to
the center line of that private street. Regarding minimum width and depth requirements,this application

appears to meet those with some possible fine-tuning of Lots 1 and 6. They may need some additional area to
meet the setbacks needed from the public street,but it appears there is room to accommodate that. The number
of traffic trips generated from this project would be about 181 new average daily trips. Applicant has proposed
sidewalks on both sides of the street. South 47th Street leading into the plat would be at full 50 foot right of
way with sidewalks on both sides. In order to extend this street and have a dead-end cul-de-sac at this point,
the Fire Department would require that the street be at full City right of way with 32 feet of travel lane and all
the homes would have to be sprinkled.
One of the biggest concerns for this plat is the precedent it would set for dead-end cul-de-sacs coming into this
parcel from 102nd Avenue SE. It has been recommended that applicant be required to provide a public street
to the south and also to the north; a public street extension that could connect to these other parcels. Applicant
had two options as to how they would be able to provide that plan. Either a 35 foot dedicated right of way on
the eastern property line that would have 28 feet of pavement, sidewalk and curb along the west side of the
street; or provide 42 feet of right of way within the plat boundaries that would be a fully developed 32 feet of
pavement with curb and sidewalks along both sides with street lighting. That would occur somewhere in the
plat. The rest of the street improvements for the plat have been analyzed by staff and are acceptable as shown
on the preliminary plat submittals. The Fire Department did grant a modification to the dead-end street length
requirement. Typically it is not allowed to have a dead-end street exceed 500 feet without sprinkling or to
exceed 700 feet total. Since this is about 930 feet from its secondary point of access,the Fire Department did
agree if there was a wider access street going in and all the units were sprinkled,that they would support this.
City standards do not support or permit the construction of a private street if adjacent property needs to be
served. If a public street were extended on the site,the area for the public right of way does need to be taken
out from the density calculations and that can affect the overall density.
The site slopes from east to west with severe slopes up to 70 percent. The area that is proposed for
development would be in the 5 to 20 percent range with the steeper slopes occurring on the western portion,
Lots 10, 11, 12 and 13. The project site is vacant along with sites to the north and south. The storm water
would be collected by a tight line conveyance system and would be routed and conveyed to the underground
detention vault just west of Lots 11 and 12. From there the storm water would be tight-lined down the slope to
the west to tie into the existing system in Springbrook Condominium. Talbot Road South does have a system
of storm water ditches. Runoff from about half an acre of the frontage improvements would be conveyed to the
on-site detention facility. There has been localized flooding in the Talbot road area in the past. The ERC did
recognize this and is requiring additional storm water detention through the 100 year storm water event to
minimize those impacts downstream. The appropriate police, fire and recreation facilities are available to serve
this proposal. Renton School District has indicated they would be able to accommodate the number of children
generated from 19 new homes.
Staff would recommend approval of this preliminary plat subject to the following: (1)compliance with the
ERC mitigation measures; (2)drafting of a homeowners association or maintenance agreement to maintain the
common plat improvements such as storm water detention vault, utility and access easements; (3)
establishment of a native growth protection easement for the area on the west that is not included in the utility
corridor. Staff has recommended modification of the plat to provide a north-south public street,but would like
to revise that to a south public street only. There are extreme slopes to the north with a quarry owned by the
State Department of Transportation, and an extension of a road would basically just fall off. The fifth
recommendation is to modify Lots 1 through 6 in order to meet the zoning and subdivision standards.

Because staff does not know at this point where the public street will be located and its affect on layout of the
lots,their sizes and setbacks, it is a general recommendation to meet requirements. The applicant is proposing
a private street for Lots 1 through 6 and a public street in a different configuration. This plat generally meets
the City's requirements,but staff feels it is appropriate to require a public street. There have been other plats
which have temporary fire turnarounds that are proposed on lots and at such time when a connection goes
through then those lots could be developed.
Staff is also asking that the applicant be required to submit a tree planting plan that would provide a minimum
of two street trees to be planted for each lot developed within the plat,or 38 trees. These would be planted in
the right of way and would be street trees approved by the City. They would need to be maintained by the
property owners and/or homeowners association.
The applicant has responded to these recommended staff conditions with a new lot layout. They are proposing
18 lots by giving up Lot 8. They are keeping their private street for access to Lots 1 through 6. Instead of
having the cul-de-sac in the center of the site, it becomes a temporary cul-de-sac off-site on the adjacent
property to the south. There is no written confirmation that that easement would be granted by the off-site
property owner. In the alternative,the applicant has stated they could pull the turnaround back and at such
point that the property to the south develops,then they could develop Lot 7 as a residential lot. Applicant has
also extended the configuration to the west slightly. Previously the lots were all held back behind the detention
basin. Now Lots 8, 9 and 12 would extend to the west slightly. Staff does not have geotechnical information
regarding that extension of Lot 12 to the west.
Colin M.Lund, 11814 115th Avenue NE,Kirkland,Washington 98034,applicant herein, addressed several
items in the staff report. He stated that they had provided and staff had concluded that the density range was 19
lots. Regarding the requirement for Lots 1 and 6 to be corner lots and meet the minimum 60 foot in width,he
stated that after discussions with staff it was concluded that Lots 1 and 6 would not be corner lots. However,
they recognized that additional setbacks may be needed than shown on the plat. A discussion then ensued
among the Examiner, Ms.Henning and Mr. Lund as to the determination of corner lots on public or private
streets.
Regarding the Fire Department right-of-way in the plat,Mr.Lund asserted that a 42 foot right-of-way would be
adequate within the plat boundaries. It would provide the same roadway improvements that a 50 foot right of
way would.
Mr.Lund addressed the conditions of approval. Regarding No.4,he concurred that it would not be possible to
put a road to the north because of the topography,but concurred that a road to the south should be provided.
Condition 6 discusses the density and applicant has provided additional information that based on the plan
submitted 19 lots would be within the permissible density range.
Mr.Lund introduced Exhibit 7,their most recent plat map, and discussed the changes from the previous plat
map. This one indicates 18 lots. The road to the south was extended and required removal of one lot.
Applicant is proposing an offsite temporary cul-de-sac turnaround,but an easement has not yet been secured.
If that option is not available, applicant would locate the cul-de-sac generally in the same location as earlier
proposed.

Mr.Lund concluded that the revised layout addressed staffs concerns and recommended conditions and was
an appropriate use of this land.
Jim Gray,Assistant Fire Marshal,City of Renton,200 Mill Avenue South,Renton,Washington 98055, stated
he had not seen the latest plat maps until the previous afternoon and was at a disadvantage to comment.
Normally a cul-de-sac of this length would not be approved without special conditions.
Paul Lumbert,Plan Review,Development Services Division,City of Renton,200 Mill Avenue South,Renton,
Washington 98055, explained that the 20 foot utility easement is basically to keep the two utilities separate
from each other,particularly in this case where one is anchored above ground and the other is buried.
The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and
no further comments from staff. The hearing closed at 10:45 a.m.
FINDINGS,CONCLUSIONS&RECOMMENDATION
Having reviewed the record in this matter,the Examiner now makes and enters the following:
FINDINGS:
1. The applicant, Jim O'Donnell,filed a request for approval of a 19-lot Preliminary Plat called Talbot
Ridge.
2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation
and other pertinent materials was entered into the record as Exhibit#1.
3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of
Non-Significance-Mitigated(DNS-M)for the subject proposal.
4. The subject proposal was reviewed by all departments with an interest in the matter.
5. The subject site is located approximately 700 feet west of 102nd Avenue SE. The site is directly west
of SE 184th Street if it were extended to the west(King County street designations).
6. The subject site is an approximately 2.7 acre parcel which is part of a larger 4.55 acre property. The
4.55 acres are divided by a Zoning District boundary that divides the site into the 2.7 acre,R-8 (Single
Family: 8 dwelling units/acre)district and a 1.85 acre,R-1 (Single Family: 1 dwelling unit/acre)
district.
7. The portion of the site which is the subject of this hearing is the R-8 portion,noted above. It appears
that the actual Zoning District line may not have been appropriately located as it was to correspond to
the demarcation between the more level portions of the site and the steep slopes found on the west
portion of the site.
8. The subject site was annexed to the City with the adoption of Ordinance 3268,enacted in December
1978.

9. The map element of the Comprehensive Plan designates the area in which the subject site is located as
suitable for the development of single family residential uses,but does not mandate such development
without consideration of other policies of the Plan.
10. In addition to the general policies found in the Comprehensive Plan there are specific policies
regarding the development of the City's street system, including grid patterns and through access. The
following policies are applicable:
Policy LU-41. Development should occur on a flexible grid street system to the extent
feasible given environmental constraints. Objective LU-M: Reduce congestion on
arterials and provide more linkages within and between neighborhoods by developing a
system of residential streets which serves both vehicles and pedestrians and creates a
continuous,efficient,interconnected network of roads and pathways throughout the
City.
Policy LU-70. Streets, sidewalks,pedestrian or bike paths in a neighborhood
development should be arranged as an interconnecting network. Cul-de-sacs should be
limited to areas where natural barriers occur. Grid pattern streets are preferable to
connect adjacent and future development.
11. The subject site is a rectangular parcel. It is approximately 660.18 feet deep(east to west)by
approximately 300.71 feet wide.
12. The approximately one-third westernmost portion of the site has very steep slopes approaching 70
percent. The remaining site has slopes that vary from 10 percent or less(the eastern half(Proposed
Lots 1-8 and 16-19))up to 20 percent for the middle section of the site.
13. The site was reviewed for wetlands on two occasions. The report found a small creek that runs north to
south east of the actual site but in the area where the access road would be developed. A small,
approximately 1,800 square foot wetland was identified. It is a Class 3 because of its small size and
limited habitat.
14. The main access to the site would be a cul-de-sac public roadway. In order to provide access to some
of the resulting parcels that would lack frontage on a public right-of-way,the applicant has proposed
creating a private north-south street to serve proposed Lots 1-6 and a roadway for Proposed Lots 9 and
10 over a separate Tract A. Proposed Lots 1 and 6 would actually front on the new public street but
would gain access from the proposed private street.
15. The applicant proposes dividing the subject site into 19 single family lots ranging in size from
approximately 4,500 square feet to 5,642 square feet.
16. Staff noted that the location of the site coupled with limited access to other parcels would require the
applicant to create a public street extending to the south. This requirement would reduce the number of
lots to 18 or less.
17. Staff also noted that the creation of a tract,Tract A, is not permitted but that a pipestem to one or both
and an easement to the other would be acceptable.

18. The proposed cul-de-sac extends beyond the 500 foot"dead-end" length permitted by the Fire
Department. It is acceptable as long as the homes are provided with sprinkler systems and the roadway
has a 32 foot wide paved roadbed and sidewalks on one side of the off-site street improvements.
19. The applicant submitted some alternative plat layouts that would extend a road south from the vicinity
of the now proposed cul-de-sac. One would extend the roadway to the south creating the actual cul-de-
sac bulb on the adjoining lot to the south. No formal agreement for use of this adjoining parcel has
been executed. Another proposal would extend the roadway south from the cul-de-sac creating an
easement for the bulb that could be dissolved allowing lot development in the future.
20. The nearest practical sewer connection is west of the site well down the steep slopes. Another
development was required to install a City sewer stub to eventually serve the area in which the subject
site is located. Similarly, storm water would need to be conveyed over and down the steep slope to a
City facility.
21. These lines will disturb the steep slope which is designated Greenbelt in the Comprehensive Plan. A
Conditional Use Permit is required to install utility lines in designated Greenbelts. In addition,the
removal of vegetation on these slopes requires a Variance under the Land Clearing and Tree Cutting
Ordinance.
22. The utility corridor will be 20 feet wide. State law requires sanitary sewer lines to be buried. The
storm water line will be aligned along the surface. The applicant will be clearing only as much of the
slope as necessary to dig its trench and bury the line. The slope would be re-stabilized with techniques
including "hill holder" devices. The slope would also be replanted to prevent erosion although the
vegetation would be such as to prevent interference with the operation or maintenance of the utility
lines.
23. The development of the subject site would generate approximately 9.55 daily vehicles trips per
dwelling. The proposed 19 dwelling units would generate approximately 181.45 trips overall. Staff
has indicated that the underlying road system can handle this traffic. Eighteen lots would generate
approximately 170 trips.
24. Development of the subject site will generate approximately 14 students. They will be spread over the
grades of the Renton School system which apparently has sufficient capacity.
25. The new roadway will run north and then west to the subject site. It will be located in both the City and
King County. It will cross State land. The State has indicated a willingness to dedicate the right-of-
way to the City. There will be approximately 980 lineal feet of roadway constructed between the
subject site and the existing road, SE 102nd Street. The new roadway will continue SE 102nd Street
north for approximately 280 feet,then will turn west where it will be South 47th Street in Renton. This
leg will be 700 feet in length. As noted,it will have a 32 foot wide road surface to provide emergency
access vehicles adequate room. Two overall widths were noted in the staff report.
26. Staff has recommended that the applicant submit a plan showing the planting of street trees.
27. A geotechnical analyses demonstrates that homes and detention system may be placed along the top of
the slope as long as certain construction standards are complied with by the applicant.

CONCLUSIONS:
Greenbelt Encroachment Conditional Use Permit
1. The applicant for a Conditional Use Permit must demonstrate that the use is in the public interest,will
not impair the health, safety or welfare of the general public and is in compliance with the criteria
found in Section 4-31-36(C)which provides in part that:
a. The proposal generally conforms with the Comprehensive Plan;
b. There is a general community need for the proposed use at the proposed location;
c. There will be no undue impacts on adjacent property;
d. The proposed use is compatible in scale with the adjacent residential uses, if any;
e. Parking,unless otherwise permitted,will not occur in the required yards;
f. Traffic and pedestrian circulation will be safe and adequate for the proposed project;
g. Noise, light and glare will not cause an adverse affect on neighboring property;
h. Landscaping shall be sufficient to buffer the use from rights-of-way and neighboring property
where appropriate; and
i. Adequate public services are available to serve the proposal.
The requested conditional use appears justified.
2. While the Comprehensive Plan designates the site for Greenbelt or low density single family uses,that
does not completely exclude the development,with reasonable protections, of utility corridors. In
addition,the Greenbelt regulations permit utility lines. The intrusion should be minimal although the
storm water line will be above the surface. Clearly a surface line will create a visual intrusion but
minimizes the disturbance of the underlying soils and the vegetation.
3. Whether there is a community need for this line is a matter of timing. This site is "hostage"to access to
utilities. The only utilities are those down below the steep slopes. If there is a community need for this
particular development and its additional housing,then there is a need for the utility lines to be
extended down a steep slope and across a designated greenbelt. It would appear that until lines are
brought in from the east,the subject site,which is zoned for eight dwelling units per acre, could not be
developed as envisioned in the Comprehensive Plan. One could argue that the Comprehensive Plan did
not truly understand the nature of this area. Property to the east of the site along the plateau is actually
less developed than the areas below along Talbot Road. Therefore,the only practical,current solution
is the proposed corridor.
4. The development of the site, if managed appropriately so that erosion or slippage does not occur,
should not affect adjacent property. The two lines are a minimal intrusion and slope restoration and
vegetation should eventually screen the refilled sewer trench and soften the appearance of the above-
ground storm line.

5. The line itself should not generate much traffic after construction activity,only periodic maintenance or
inspections, and not be out of scale due to the nature of the project. There should not be any
unacceptable noise, light or glare once construction is completed.
6. The slope will be replanted with appropriate materials to prevent slippage or erosion but allow
maintenance.
Land Clearing Variance
7. Variances may be granted when the property generally satisfies all the conditions described in part
below:
a. The applicant suffers undue hardship caused by special circumstances such as:the size, shape,
topography,or location where code enforcement would deprive the owner of rights and
privileges enjoyed by others similarly situated;
b. The granting of the variance would not materially harm either the public welfare or other
property in the vicinity;
c. The approval will not constitute a special privilege inconsistent with the limitations on other
property in the vicinity; and
d. The variance is the minimum variance necessary to allow reasonable development of the
subject site.
The applicant's property appears ripe for the variance requested.
8. It appears that the only reasonable corridor for the two utility lines is across the vegetated steep slope.
The location of the site makes any other route impractical since there are no sewer lines to hook up to
other than the one below the slope. Additionally,the storm line needs gravity which necessitates
dropping the storm line over the bank and down the slope.
9. The approval will alter the natural surface of the site,but if done correctly should not cause any long
term harm to neighboring properties or the public welfare.
10. The approval should not grant the applicant a special privilege. The lines will be available to serve
other nearby properties,reducing the need for similar intrusions into other areas along this slope. In
addition,the unique circumstances should limit the precedent created by granting this variance.
11. The land clearing should be limited to the immediate vicinity of the two lines. The trenched line will
require more width but will not require the removal of vegetation from the entire easement width. The
surface line will require less ground disturbance. The areas disturbed will be the minimum necessary
to accomplish the work.
Preliminary Plat
12. The proposed plat, subject to the conditions noted below, appears to serve the public use and interest.
Although it might be premature to develop the subject site due to the need to step around a variety of
Jim O'Donnell
Talbot Development Partners,LLC

File No.: LUA-97-087,PP,CU-H,V
December 4, 1997
Page 11
limitations, staff has noted that the proposal is compatible with the Comprehensive Plan and Zoning
which both call for up to 8 homes per acre. The development will provide additional housing choices
although extending services to this area does require both a Conditional Use and Variance to provide
the site with sanitary and storm water systems. In addition, an access road must be extended without a
master plan of where the street grid system will be located which will ultimately serve the site and
surrounding area.
13. The plat represented by Exhibit Number 7 with the Exhibit Number 8 overlay shall be the plat that is
developed for this project if it can be demonstrated that it meets the necessary code provisions for lot
area and setback for front yards and corner lots. The cul-de-sac shall be created solely on the subject
site and the off-site cul-de-sac is not approved. Preliminary Plat approval is not speculative. While
modest alterations might be accommodated,a specific plan for streets as well as the various utilities is
necessary for the approval of a Preliminary Plat. It is inappropriate to approve a conjectural plan at this
time. In addition, since development of the adjacent properties may not occur for a long period of time,
any cul-de-sac may be a long term access requirement. Therefore,while it may be created as an
easement which may be dissolved if the roadway is extended creating a through grid pattern, all lots
shall have sufficient lot area exclusive of any such easement at this time. That is,all lots lying around
the cul-de-sac shall contain 4,500 square feet exclusive of any easement property. This is similar to the
requirement that all lots shall have the minimum lot area exclusive of any pipestem access. Again,any
extension that creates a through street system could be years off and all lots should have the minimum
lot area as well as front, side and rear yard areas.
14. The creation of a separate legal tract to provide access to interior lots is inappropriate, creating
maintenance and ownership complications that can be avoided. The applicant shall provide the
appropriate access to any interior lots over an easement roadway and not a separate tract.
15. The private street to provide access to Proposed Lots 1 - 6 appears reasonable, although a more long-
term street grid system probably should have been carefully analyzed so that the applicant would have
had more information on which to base some of their plat decisions.
16. Since access to the site is basically a long dead-end street and emergency access in such a situation is
very important, all rights-of-way within the site shall be developed to the City's 50(fifty)foot roadway
standards.
17. The lots appear to be as rectangular as possible given the need for a cul-de-sac bulb to accommodate a
turnaround location and emergency access.
18. The development will increase the tax base of the City. It appears that utility services can be extended
to serve the site.
19. As staff has suggested,the applicant shall submit a tree planting plan showing a minimum of two(2)
street trees for each lot,although the distribution shall be altered as determined by the City.
20. In conclusion,while many aspects of the plat still appear vaguely defined,the concept after staff
calculates the lot area,yard setbacks and appropriate zoning demarcation,generally appears to serve
the public use and interest. The matter will not be forwarded to the City Council for review until a plat
has been submitted to staff which meets all requirements and said plat has been submitted to the
Hearing Examiner with a written statement indicating that each lot meets all City standards within sixty

(60)days of publication. If such a plat and written documentation is not submitted in a timely fashion,
the matter will be reopened for additional public hearing.
DECISION AND RECOMMENDATION
The Conditional Use Permit and Variance are approved,as is a Preliminary Plat for 16 to 18 lots
subject to the following conditions:
1. The preliminary plat map demonstrating the appropriate aspects of Exhibits 7 and 8 shall be
resubmitted for review by staff who shall forward said plat and written documentation indicating that
each lot meets all City standards within sixty(60)days of publication. If such a plat and written
documentation is not submitted in a timely fashion,the matter will be reopened for additional public
hearing.
2. All lots shall have sufficient lot area exclusive of any easement. That is,all lots lying around the cul-
de-sac shall contain 4,500 square feet exclusive of any easement property.
3. All public rights-of-way within the site shall be developed to the City's 50(fifty)foot roadway
standards. The cul-de-sac shall meet all turning radii standards.
4. The applicant shall submit a tree planting plan showing a minimum of two(2)street trees for each lot,
although the distribution may be altered as determined by the City. The applicant shall post a bond to
assure compliance with this condition. The City shall be responsible for planting the trees.
5. All land clearing both in the plat and particularly along the steep slopes shall be as limited as possible.
In the steep slopes all clearing shall be limited as much as practical to the immediate vicinity of the two
utility lines.
6. The applicant is required to comply with the mitigation measures which were required by the ERC
prior to the issuance of a construction or building permit.
7. The applicant shall draft and record a maintenance agreement or establish a homeowner's association
for the maintenance of all common plat improvements(storm water detention vault,utility easements,
access easements). A draft of the document shall be submitted to the City for review and approval by
the City Attorney prior to the recording of the plat.
8. The applicant shall define and record a Native Growth Protection Easement on the face of the plat for
the steep slope areas west of the storm water detention vault. The applicant shall adhere to the City
code requirements for such areas.
9. The access tract shown for any lots shall be eliminated and that area incorporated into one of the lots as
a pipestem,with an access easement for the other lot.
10. The applicant shall be required to install slope stabilization devices as recommended by the applicant's
engineer or geotechnical consultant.

request shall set forth the specific ambiguities or errors discovered by such appellant,and the Examiner may,
after review of the record,take further action as he deems proper.
An appeal to the City Council is governed by Title IV, Chapter 8, Section 16,which requires that such appeal
be filed with the City Clerk,accompanying a filing fee of$75.00 and meeting other specified requirements.
Copies of this ordinance are available for inspection or purchase in the Finance Department,first floor of City
Hall.
If the Examiner's Recommendation or Decision contains the requirement for Restrictive Covenants,the
executed Covenants will be required prior to approval by City Council or final processing of the file.
You may contact this office for information on formatting covenants.
The Appearance of Fairness Doctrine provides that no ex parte(private one-on-one)communications may
occur concerning pending land use decisions. This means that parties to a land use decision may not
communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use
process include both the Hearing Examiner and members of the City Council.
All communications concerning the proposal must be made in public. This public communication permits all
interested parties to know the contents of the communication and would allow them to openly rebut the
evidence. Any violation of this doctrine would result in the invalidation of the request by the Court.
The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as
Appeals to the City Council.

HEARING AMNER
CITY OF RENTON
PLANNINGBUILDING/PUBLIC WORKS
MEMORANDUM
DATE: November 19, 1997
TO: Fred Kaufman,Hearing Examiner
FROM: Jennifer Toth Henning al\
SUBJECT: Talbot Ridge Preliminary Plat(File No. LUA-97-087,PP,CU-
H,V,ECF)
After the public hearing today, I researched some of the items discussed and would like to add the
following information to the project file:
Schools. The factor used to calculate the average number of school-age children generated by
residential development is discussed in the Renton Draft EIS for the Land Use Element of the
Comprehensive Plan(January 1992) The Renton School District uses the following factors:
Single Family Residential:
Elementary: 0.443 children per unit
Middle: 0.171 children per unit
High: 0.145 children per unit
TOTAL: 0.759 children per single family residential home
A total of school-age 14.4 children would be expected to reside in the proposed 19 homes (0.759
children/unit X 19 homes)= 14.4 children.
Density Calculations. The revised density calculation sheet for the proposed plat, as discussed during
the public hearing is attached. All of the area of the parcel was included minus sensitive areas, and
the public right-of-way (South 47th Street). The calculation assumes that all of the area zoned R-8
(from the top of slope to the east)minus the public right-of-way is available for development.
This differs from the discussion in the staff report(page 10,,item 7(b)) in that staff did not previously
consider all of the R-8 area in the density calculation. That portion of the subject property east of the
top of slope and west of the proposed property lines for lots 10 through 13 is within the R-8 Zone, and
is not considered to be sensitive, or greenbelt. Therefore, this area (shown in diagonal lines on the
attached map)should have been included in the original analysis.
Based on this,the applicant would be able to provide a minimum of 13 dwelling units, or a maximum
of 19 dwelling units and be within allowable density of 5.0 to 8.0 du/acre. With 19 lots the density
would be 7.68 du/acre.
Street Names. According to Code Section 9-11-2, private roads (streets) with three or more houses
are designated according to the adopted City street grid system. The proposed private street within the
plat would be assigned a name in accordance with the grid, and would likely be named,either: Burnett
November 18, 1997
Page 2
Place South, or Burnett Court South, or Burnett Lane South. Since this would not be a public street,
the street name sign would indicate"private street"or"private road". A new north/south public right-
of-way would likely be assigned the name Burnett Avenue South per Code Section 9-11.
Number of Existing Parcels. The subject site is presently one parcel. The applicant provided a copy
of a title report that is included in the project file. A lot line adjustment was approved in 1996 as part
of the Springbrook Residential Development project (File No. LUA-96-004, SA, LLA, ECF).
Previously the Talbot Ridge site was a portion of two east/west lots that extended from Talbot Road
to the eastern boundary of the Talbot Ridge site. King County recorded the lot line adjustment under
recording number 9609179003. The east/west property line was dissolved and a north/south property
line created at the bottom of the steep slope area as part of the lot line adjustment.
Staff Recommendation No. 7 (page 14 of Preliminary Report to the Hearing Examiner). Based
on further staff discussion,we would like to revise the Recommended Condition No. 7 for the planting
of street trees. The recommendation should state: "The applicant/owner shall be required to submit
a tree planting plan which provides for the installation of street trees along the 50-foot wide public
right-of-way leading into the plat (South 47th Street and/or 102nd Avenue SE). The minimum
number of trees to be planted is equal to two trees per lot. The type of trees installed is subject to
review and approval of the City's Development Services Division project manager. Installation
would be required at the same time that plat improvements are installed. Maintenance of the trees
would be the responsibility of the individual homeowner, or the homeowner's association."
This proposed revision stems from the practical difficulty of enforcing and inspecting for the
previously recommended condition on a lot-by-lot basis. Installing the street trees in the public right-
of-way leading to the plat, rather than inside the plat, simplifies matters since the trees could be
installed with street improvements, rather than having the requirement tied to individual building
permits.
Please feel free to contact me at Extension 6186 if you have any questions.
Talbot Ridge 11/18/97
City of Renton
Density Worksheet for Development in the R-8 Zone
According to Renton's City Code, the standards for new development in the R-8 Zone
require that residential densities fall within a range of 5 to 8 dwelling units per net
developable acre. (Section 4-31-5.D.2) The code does not require that the lots be developed
simultaneously. However, the land must be platted so as not to preclude future development at
an appropriate density.
1) Total parcel size minus street r-o-ws and sensitive areas: . 107820.80 square feet
2) Net Acreage (line 1 divided by 43560): 2.48 acres
dwelling units net density
3) Maximum and minimum allowed dwelling units Max. 19 7.68 units/net acre
and respective net densities: Min. 13 5.25 units/net acre
4) 107820.80 sq ft and - 19 dwelling units result in a density of 7.68 d.u./acre.
Deductions from gross area: 19,718.5 for roadway.

1.0 INTRODUCTION
This report presents the results of our subsurface exploration and preliminary geotechnical
engineering feasibility study for the proposed 19 lot single-family home, and storm water
detention vault located approximately one-fifth of a mile west of the end of 102' Avenue SE
(Figure 1). The proposed vault and lot layout and the approximate locations of the
explorations accomplished for this study are presented on the Site and Exploration Plan, Figure
2. After site access is available for construction equipment, additional exploration pits are
recommended to verify subsurface and shallow ground water conditions in the vault and home
areas. In the event that any changes in the nature, design or location.of the structures are
planned, or if subsurface conditions are found to differ significantly from those encountered in
the explorations for this study, the conclusions and recommendations contained in this report
should be reviewed and modified, or verified, as necessary.
1.1 Purpose and Scope
The purpose of this study was to provide subsurface data and preliminary geotechnical
recommendations to be utilized in the design and development of the subject project Our
study included a review of available geologic literature, 9 hand borings, and performing
geologic studies to assess the type, thickness, distribution and physical properties of the
subsurface sediments and shallow ground water conditions. Preliminary geotechnicaI
engineering studies were also completed to determine slope building setbacks from the top of
the on-site slope, the type of suitable foundation, allowable foundation soil bearing pressures,
anticipated foundation settlements and drainage considerations. This report summarizes our
current field work and offers development recommendations based on our present
understanding of the project and surrounding geologic conditions.

1.2 Authorization
Verbal authorization to proceed'with this study was granted by Mr. Brian Johnson of Triad
Associates on behalf of the owner, Talbot Development Partners, L.L.C. Our work was
completed in accordance with our proposal dated June 10, 1997 and subsequent discussions
with Brian Johnson. This report has been prepared for the exclusive use of. Talbot
Development Partners, L.L.C. and their agents, for specific application to this project. Within
the limitations of scope, schedule and budget, our services have been performed in accordance
with generally accepted geotechnical engineering and engineering geology practices in effect in
this area at the time our report was prepared. No other warranty, expressed or implied is
made. Our observations, findings, and opinions are a means to identify and reduce the
inherent risks to the owner.
2.0 PROJECT AND SITE DESCRIPTION
This report was completed with an understanding of the project based on a site plan with
topographic information referenced as Preliminary Plat Talbot Ridge, sheet 1 of 4, completed
by Triad Associates dated June 5, 1997, that showed the site with elevation contours, the
planned locations of lots, paved roadways, and the detention vault. The proposed development
area in the upper, eastern portion of the property measured roughly 380 feet east-west by 300
feet north-south with a change in elevation of approximately 40 feet. West of this area, slope
gradients steepen to approximately 50 percent with a vertical relief of about 100 feet on the
Property.
We understand that the development will include 19 single family lots, an approximate 900
foot long extension of SE 183n1 Place, and construction of a storm water detention vault.
The 20 foot (east-west) by 100 foot (north-south) by 12 foot deep storm water detention vault
will be located on the west end of the proposed housing development (Figure 1). Borings HB-
1, HB-2 and HB-3 were completed on June 16, 1997 in the original vault location. Since then,
the detention vault was moved approximately 35 feet west and 20 feet south to the current
location shown on Figure 1. H3-9 was located in the new vault area.
The 900 foot long extension of SE 183cd Place will run west from 102' Avenue SE and end in
a cul-de-sac in the central portion of the development area. Elevation change across the road
length will be approximately 20 feet.
Vegetation on the site consisted of fir and cedar trees with moderate to thick underbrush.
Other land uses in the vicinity consisted of residential and undeveloped land.

3.0 SUBSURFACE EXPLORATION
Our field study included advancing a series of 9 hand borings to gain information about the
subsurface soil and shallow ground water conditions at the site. . The various types of
sediments; as well as the depths where characteristics of the sediments changed are indicated
on the exploration logs presented in the Appendix. The depths indicated on the logs where
conditions changed may represent gradational variations between sediment types in the field.
Our borings were approximately located in the field by measuring from known site features
shown on the site and topographic map.
The conclusions and recommendations presented in this report are based on our geologic
reconnaissance. and the hand borings completed for this study. Because of the nature of
exploratory. work .below ground and limited depth capability of hand exploration methods,
extrapolation of subsurface conditions is necessary, and it should be noted that differing '
subsurface conditions may sometimes be present due to the random nature of deposition and
the alteration of topography by past grading, or.filling. The nature and extent of any variations
in soil conditions may not become fully evident until equipment access is secured for
exploration pits or until construction. If variations are observed at that time, it may. be
necessary to re-evaluate specific recommendations in this report and make appropriate changes.
3.1 Hand Borings
Hand borings HB-1 through HB-3 were completed on June 16, 1997 and HB-4 through HB-9
were completed on November 7, 1997 using hand auger methods. Materials encountered from
the borings were studied and classified by a geologist from our firm. All borings were
backfilled after examination and logging. Selected samples were' then transported to our
laboratory for further visual classification as necessary.
4.0 SUBSURFACE CONDITIONS
A review of the Geologic Map of the Renton Quadrangle, King County, Washington by D.R.
Mullineaux 1965 showed that the soils within the lower portions of the property (including the
vault location) consisted of undifferentiated glacial deposits. Soils within the upper portion of
the property (home and road locations) were mapped as glacial moraine deposits. Our
interpretation of the sediments encountered in our hand auger holes generally agree with the
geologic map, as discussed below.
Subsurface conditions on the parcel were inferred from the field explorations accomplished for
this study, visual reconnaissance of the site and review of published geologic literature. As
shown on the field logs, the upper portion of the borings generally encountered about 1/2 to 2
feet of loose, moist, dark brown to brown silty sand (topsoil) with varying amounts of roots
and other organic materials.
3
11'/17/97 13:36 22206 82 l81 TRIAD ASSOCIATES V1 006
The encountered undifferentiated glacial deposits generally consisted of loose/soft, grading to
medium dense/stiff, damp to moist, brown, silty sand to sandy silt. Some organics, scattered
cobbles and gravel lenses were also encountered_ These sediments were encountered in HB-1,
HB-2, HB-3, HB-4, HB-6, HB-7 and'HB-9.
In HB-1, HB-2, HB-3 and HB-9 these undifferentiated glacial deposits extended to below the
termination depth of the borings (deepest at 7 feet 6 inches below surface grade).
Beneath the undifferentiated glacial deposits in HB-4, HB-6 and HB-7 and near the surface in
HB-5 and HB-8, dense glacial moraine deposits were encountered. The glacial moraine
- deposits generally consisted of dense/stiff to hard, moist, reddish-brown, very fine to medium
sand and silt with varying amounts of gravel. In HB-4, HB-6 and HB-7, the depth to dense
glacial moraine deposits were 3.5 feet, 4 feet, and 3.5 feet, respectively. In HB-5 and HB-8,
dense sediments were encountered approximately 1 to 2 feet below the surface.
4.1 Hydrology
•
Ground water seepage was not encountered in the borings at the times of our field studies.
The location and rate of ground water seepages may vary with changes in rainfall.
A drainage swale was present adjacent to 102' Avenue SE. and sloped down to the northwest.
Based on a USGS topographic map, this is a seasonal drainage that is only affected by heavy
precipitation_

II. PRELIMINARY DESIGN.RECOMMENDATIONS
5.0 INTRODUCTION
Our explorations, geologic reconnaissance and interpretations of published geologic Iiterature
indicate that from a geotechnical standpoint, the site is suitable for the proposed development.
The bearing strata (medium dense to dense sand or stiff to hard silt) was relatively shallow
(within 1 to 3 feet of ground surface) in most of our exploration borings_ No evidence of past
landslide or debris flow activity was observed in the vicinity of the vault or the lots, nor were
they mapped in the geologic literature.
It is our opinion that the vault and homes may be constructed using a conventional, shallow
foundation and retaining walls, without a significant adverse impact on slope stability.
Provided that the foundation and drainage recommendations in this report are followed, no
setback of the house or vault foundations from the slopes are required from a geotechnical
standpoint.
6.0 SITE PREPARATION
•
Site preparation for the planned vault and homes should consist of stripping and removing the
upper, organic topsoil horizon. This material may be.set aside for later reuse as a mulch layer
to promote germination and growth of natural plants. Once the foundation footprint is
stripped, excavation for the foundations may proceed. It is anticipated that the depth of
foundation excavations below existing grade will be on the order of 6 feet for the vault and 2 to
3 feet for the homes. Based on our exploration borings, we anticipate loose, grading to dense,
silt, sand and gravel sediments will be encountered. We do not expect that significant ground
water seepage will be encountered in the excavations, however, seepage zones may occur
during the wetter periods of the year.
The on-site sediments contained a high percentage of fine-grained material which makes them
moisture sensitive and subject to disturbance when wet. The contractor must use care during
site preparation and excavation operations so that the underlying soils are not softened. If
disturbance occurs, softened soils should be removed and the area brought to grade with
structural fill compacted to a minimum of 95 percent of ASTM:D-1557 (modified Proctor).
5
11'/17/97 13:37 22206 82 81 TRIAD ASSOCIATES Zoos
Once the excavation is completed to the required depths and any softened soils removed and
replaced by structural fill, the subgrade should be recompacted to at least 95 percent of the
above standard prior to foundation construction_ After the subgrade is prepared and approved
by the geotechnical engineer, foundation construction can begin_
7.0 STRUCTURAL FILL
For the proposed development we do not anticipate the need for structural fill under home
Iocations. However, structural fill will be required to backfill utility trenches within the
planned roadway. The on-site soils will be suitable for structural fill if placed within
approximately 2 percent of the optimum soil moisture content. As previously mentioned, the
on-site soils are moisture-sensitive and near optimum moisture content. Therefore, their use as
structural fill should be limited to favorable dry weather and dry subgrade conditions.
Structural fill is defined as non-organic soil, acceptable to the field engineer, placed in
maximum 8 inch Ioose lifts, with each lift compacted to at least 95 percent of the modified
•
Proctor maximum density (ASTM:D-1557). The top of compacted fill should extend
horizontally outward a minimum distance of 3 feet beyond pavement edges before sloping
down at a maximum angle of 2H:1 V (Horizontal:Vertical).
A representative from our firm should be present during the placement of structural fill to
observe the work and perform a representative number of in-place density tests.
8_Q FOUNDATIONS
Conventional spread footings may be used for support of the vault and homes when founded on
the medium dense to dense natural sands, stiff silts, or structural fill placed as previously
discussed. For the vault, we recommend that an allowable soil bearing pressure of 2,500
pounds per square foot (psf) be utilized for design purposes, including dead and live loads.
For the homes, we recommend that an allowable soil bearing pressure of 2,000 psf be utilized
for design purposes, including dead.and live loads. For frost protection all exterior footings
must be buried at least 18 inches below surrounding grades. However, all footings must
penetrate to the prescribed bearing strata and no footings should be founded in or above
loose/soft or organic soils. All footings should have a minimum width of 16 inches.
The area bounded by lines extending downward at a 1 H:l V inclination from any footing must
not intersect another footing or intersect a filled area which is not being compacted to at least
95 percent of ASTM:D-1557.
•
Anticipated settlement of footings founded on medium dense to dense sand, stiff silt or
approved structural fill should be less than I inch_ However, disturbed soil not removed from
footing excavations prior to footing placement, could result in increased settlements. All
6
11/17/97 13:37 22206 82- -,81 TRIAD ASSOCIATES I ]009
footing areas should be inspected by Associated Earth Sciences, Inc. (AESI) prior to placing
concrete to verify that the design bearing capacity of the soils has been attained and that the
construction conforms to the recommendations contained in this report. Such inspections may
also be required by the governing municipality.
9.0 TEMPORARY AND PERMANENT CUT SLOPES
In our opinion, stable construction slopes should be the responsibility of the contractor and
should be determined during construction based on the encountered soil and ground water
conditions. For estimating purposes, we anticipate that temporary, unsupported cut slopes in
the silt, sand and gravel sediments may be made at a maximum slope of 111:1V. As is typical
with earthwork operations, some sloughing and raveling may occur and cut slopes may have to •
be adjusted in the field_ In addition, WISHA/OSHA recommendations should be followed at
all times. Permanent cut slopes may be made at a maximum slope of 2H:1V.
10.0 LATERAL WALL PRESSURES
Horizontally backfilled walls which are free to yield laterally at least 0.1 percent of their height
may be designed using an equivalent fluid equal to 35 pounds per cubic foot (pcf)_ Fully
restrained, horizontally baclfilIed rigid walls which cannot yield should be designed for an
equivalent fluid of 50 pcf. The upper, east wall of the vault will likely have a sloping backfill
condition at an approximate inclination of 5H:1V and should be designed for an equivalent
fluid of 40 pcf for yielding conditions and 60 pcf for restrained conditions. The lateral
pressures presented above are based on the conditions of a uniform backfill consisting of a
select on-site sand/silt and/or gravel backfill compacted to 90 percent of the ASTM:D-1557. A
higher degree of compaction is not recommended as this. will increase the pressure acting on
the walls.
•
Proper drainage must be provided so that hydrostatic pressures do not.develop against the
walls. This would involve installation of a minimum 1 foot wide blanket drain for the full
height of the wall using imported, washed gravel. A perforated, rigid, PVC pipe should be
placed at the wall base elevation and sloped to drain to a suitable outlet location. The drain
pipe must be hydraulically connected to the wall blanket drain.
11.0 DRAINAGE RECOMMENDATIONS
•
All perimeter foundation and retaining walls should he provided with a drain at the base of the
wall. Drains should consist of rigid, PVC, perforated pipe baclffilled within 1 foot of ground
surface with washed drain rock. The size of the drain rock must be greater than the diameter
of the pipe perforations. The bottom of the pipe should be set approximately 2 inches below
the bottom of the foundation and should he constructed with sufficient gradient to allow gravity
7
11%17/97 13:38 22206 82: - 81 TRIAD ASSOCIATES ti O10
discharge away from the homes. Roof and surface runoff should not discharge into the footing
drain system but should be handled by a separate tightline drain_ In planning, exterior grades
adjacent to walls should be sloped downward away from the structures to achieve surface
drainage. All drains must be tightlined to a suitable engineered storm water conveyance
system.
12.0 SLOPE REMEDIATION
Once the vault and outfall pipe are constructed, the areas disturbed by the construction should
be restored and planted to reduce the potential for erosion and slope instability. In general, we
recommend that the following measures be used.
•
1. All excavations should be hack filled with granular, natural soils derived from
on-site, and compacted to at least 90 percent of ASTM:D-1557.
2. Finished grades should be contoured to blend into the surrounding natural
slopes, and to avoid concentrated flows of runoff water. Concentrated runoff
must not be directed onto or above more steeply sloping areas of the site_
3_ Disturbed areas should be revegetated with a suitable hydroseed mixture. To
promote plant germination and growth, mulching the slopes with the on-site
topsoil sediments is recommended prior to hydroseeding. The mulch/topsoil
thickness should not exceed 1 foot.
13.0 CLOSURE
At time of this report, site grading, structural plans, and construction methods had not been
finalized. The recommendations presented in this report are therefore preliminary and should
be reviewed and/or modified as necessary as new design infortlaation becomes available. We
are available to provide additional geotechnical engineering exploration or consultations as the
project design develops and possibly changes from that upon which this report is based.
We are also available to provide geotechnical engineering and monitoring services during
•
construction. The integrity of the foundations depends on proper site preparation. and
construction procedures. In addition, engineering decisions may have to be made in the field
in the event that variations in subsurface conditions become apparent.

Re: Wetland investigation: Talbot Ridge Preliminary Subdivision -
City of Renton.
Dear Mr. Lund:
•
Per your request, a wetland investigation was conducted on November 9, 1997. The Talbot
Ridge project Is a preliminary residential sut)rlivision plat on approximately 4.5 acres. The
subject site Is located west of the end of 102nd Avenue S.E. within the city of Renton • King
County, Washington (Section 31, Township 23 North. Range 5 East, WM).
The proposed access is a 50-foot right-of--way, about /00 feet long, that wilt extend from 102nd
Avenue S.E. Most of the right-of-way area consists of mature, deciduous upland forest but
includes a small drainage corridor that will need to hot Crossed_ A wetland/stream investigation for
the proposed right-of-way crossing was conducted during the summer of 1997 (Schulz-Letter
Report, 7/30/97).
Site/Project Description
The Talbot Ridge subdivision proposal consists of 19 rlew residentiai lots. The Talbot Ridge site
is also a forested area extending to the east valley rim of steep slope areas. No significant
development is proposed on the steep slope area.
According to the King County Area Soif Survey (US Soil Conservation Service 1973), the
property is mapped as Alderwood gravelly sandy loam soil, 6 to 15 percent slopes (AgC). The
Alderwood mapped soil unit Is associated with upland habitats. Smaller areas of poorly drained
Soils included within this map unit are reported its Norma, Bellingham, Seattle, Tukwila, and
Sh altar series.
The site is described as having a mixed deciduous, forest cover throughout the plateau area_
Dominant tree species include red alder(Alnus rubra) and big leaf maple (Acermacrphyffum) with
some scattered Douglas lir(Pseudotsuga menziesir) and western red cedar(Thuja p/icata)conifer
trees. The western slope area Is an open forest comprised or mostly intermediate-aged Douglas
fir mixed with some big leaf maple trees. Shrub and groundcover spades are typical of the Pacific
Northwest and the majority are mostly found growing in upland habitats.

investigation Findings •
The Talbot Ridge site was field-Investigated on 11/9/97 for the potential presence cif wetland
habitat. The site visit included walking the steep slope area on the west side of the property.
The methodology used is consistent with the U.S. Army Corps of Engineers 1987 Wetlands
Delineation Manual (Environmental Laboratory 1987). Three 0.01-acre data plots were
established on the site and soli samples were taken :at all data plots. Data plot field forms are
attached to this report with an approximate location real)_
In summary, all soil investigations found the Alderwond series associated with upland areas. No
surface water drainage or groundwater seepage was observed. As a result,wetland habitat was
also not observed anywhere on the subdivision project property.
If there are any questions or concerns regarding this investigation report, please feel free to
contact rne.
Sincerely.

RE: Talbot Ridge
Triad Job No. 97-006
Dear Jennifer:
Here is a copy of the new preliminary layout for Talbot Ridge. There were a few minor
changes to the original layout as depicted on the attached drawing. I have prepared the
new density calculations as indicated below for this revised proposal_ The density range,
based on our calculations, is between 13 and 19 lots for the property. We did,however, •
lose one lot as a result of the road stub to the south and are now down to 18 lots.
•
The new density calculations are as follows:
• Total parcel size(including detention) 125298 sq. ft
• Sensitive areas 155 sq_ ft
• R-O-W 18154 sq. ft
I) Total parcel size minus street r-o-w's and sensitive areas: 106989 sq_ ft
2) Net Acreage 2.46 acres
dwelling units net density
3) Maximum and minimum allowed dwelling max 19 7.72.
• units and respective net densities mini 13 5.28
4) 106989 sq. ft and 18 dwelling units result in a density of 7.32 d.u./acre
As noted above, the new layout shows a stub which will provide access to the southern
property per your request. However,Colin and T visited the site after our Monday
meeting to check the feasibility of an additional stub road to the north and it is physically
not feasible. The slope to the north which we discussed at our meeting is extremely steep,

in excess of 40%(sloping down into the gravel pit at least 150-200 feet below the
elevation of Talbot Ridge). Therefore, a northern access stub is not feasible and should
not be required for this project.
Should you have any additional questions with the new layout and/or density calculations,
or would like to discuss these issues any further, please don't hesitate to contact me, 821-

PROJECT NAME: Boeing Crew Shelters
PROJECT NUMBER: LUA-97-143,CU-H,ECF
DESCRIPTION: In 1990 the Boeing Company obtained a conditional use permit(CU-081-
90)to locate ten Crew Shelters and a Crew Support Building on Aprons B &C of the Renton Municipal
Airport. This permit was given a termination date that has now expired. The Boeing Company is
requesting a new permit in order to continue the use of the buildings in their existing locations. A
Temporary Use Permit for the buildings was issued to cover the time period until the City can consider
the new application. The Crew Shelters and Crew Support Building are used to provide a location for
Boeing's employees to read blue prints and store tools while working on the adjacent aircraft. If the
conditional use permit is approved there will be no change in the site as the buildings will remain where
they are presently located. Location: Aprons B &C Renton Municipal Airport(West side of main
runway).
PROJECT NAME: Talbot Ridge Preliminary Plat
PROJECT NUMBER: LUA-97-087,PP,ECF,CU-H,V
DESCRIPTION: The applicant, Triad Associates, proposes to subdivide 4.55 acres of a
vacant site into 19 lots for single family homes. The site is zoned R-1 and R-8. Project requires
environmental review, preliminary plat approval, conditional use permit and variance to construct storm
sewer lines in a steep slope/greenbelt area. A new street would be extended from 102nd Avenue SE to
serve the plat. Location: 600 feet east of 102nd Avenue SE and SE 184th.
PROJECT NAME: GTE PCS Monopole/Duvall-Continuation
PROJECT NUMBER: LUA-97-103,CU-H,V-H,ECF
DESCRIPTION: GTE proposes to construct a Personal Communications Service (PCS)
facility located at 1160 Duvall Avenue NE. The proposed facility calls for a 120 foot monopole with three
(3) antenna arrays. Each antenna will include four (4) PCS antenna (approximately 60" x 6") for a total
of 12 antennas. Site development will also include two equipment cabinets. Each cabinet will be
approximately 8 feet long by 2.5 feet wide by 6 feet tall. The total project area will be approximately 800
square feet. The applicant is seeking a variance of 285 feet from the required 300 foot setback from
• residential property and a variance from the height limit of 65 feet to allow a 120 foot monopole
structure. Ordinance 4666 which became effective on June 2, 1997, prior to the submittal of this
application, list this proposed monopole structure as a prohibited use as it is within 300 feet of property
zoned R-8. Location: 1160 Duvall Ave. NE.

G. DEPARTMENT ANALYSIS:
1. PROJECT DESCRIPTION/BACKGROUND
The applicant proposes to subdivide 4.55 acres of a vacant site into 19 lots suitable for the development
of single family residential homes. The resulting parcels would range in size from 4,500 square feet to
5,642 square feet. A new public street (South 47th Street) would be extended west from 102nd Avenue
SE to serve the plat. And, 102nd Avenue SE would be extended north from SE 185th Place.
Approximately 980 lineal feet of the new 50-foot wide right-of-way street would be located off-site, on
land presently owned by the State of Washington. Of this, 700 lineal feet would be within the City of
Renton, and 280 feet would be the extension of 102nd Avenue SE, a King County street. The.3,500
square feet of land on State land that would be developed as South 47th Street would be dedicated to
the City of Renton. Negotiations are currently underway with the Washington Department of
Transportation to transfer title of that portion of the property to the City.
A 26-foot wide private street (Burnett Avenue South) would provide access to new lots Nos. 1 through 6,
although Lots 1 and 6 would also have access to the new public street. An access easement would
provide vehicular access to new Lots No. 9 and 10 from the cul-de-sac of the public street.
Development would occur on approximately 2.7 acres of a 4.55 acre site. The new parcels would be
created on the eastern half of the site, which is zoned Residential - 8 dwelling units per acre (R-8). The
western half is zoned R-1 due to the steep slopes. Only the construction of a sanitary sewer line,
stormwater detention vault, and stormwater conveyance facilities is proposed to occur on the western
portion of the property.
A site-specific wetland investigation report was prepared to determine whether wetland habitat was
present in the off-site area proposed for the public right-of-way. The report determined that an
unclassified steam flows from south to north through the area of the proposed road. The area is partially
within the jurisdiction of both the City of Renton and King County. A small wetland was identified
associated with the stream. The delineated wetland exists within the stream corridor and the delineated
area is approximately 1,800 square feet in size. Most of the riparian area existing within King County's
jurisdiction. According to the King County Sensitive Areas Ordinance, the riparian area of the stream
would be rated a Class 3 because of it's small size and limited habitat. The stream is not rated by the
City of Renton, and could be rated Class 3 because it is seasonal and does not support salmonid fish
species. The stream is mapped as a tributary to Panther Creek, located to the north.
Construction of the proposed right-of-way would result in the placement of fill and culverting of an area of
approximately 9000 square feet. Half of this impacted area would be within King County, and the
remainder in Renton.
The site is zoned both R-1 and R-8. The proposal requires environmental review, preliminary plat
approval, conditional use permit and a variance to construct storm sewer lines in a steep slope/greenbelt
area.

5. CONSISTENCY WITH CONDITIONAL USE CRITERIA
City Code Section 4-31-35F.2 requires a Conditional Use Permit for the construction of utilities in
a designated greenbelt area. The subject application includes construction of stormwater and
sanitary sewer lines within the greenbelt portion of the site. The following analysis discusses
only the construction of the proposed utility lines.
Section 4-31-36 lists 11 criteria that the Hearing Examiner is asked to consider, along with all
other relevant information, in making a decision on a Conditional Use application. These include
the following:
(5A) CONSISTENCY WITH THE COMP. PLAN, ZONING CODE& OTHER ORDINANCES:
The proposed use shall be compatible with the general purpose, goals, objectives and standard
of the Comprehensive Plan, the Zoning Ordinance and any other plan, program, map or
ordinance of the City of Renton.
(1) COMPREHENSIVE PLAN LAND USE ELEMENT
The proposed storm and sanitary sewer lines would be constructed in a steep slope area
of a designated greenbelt. The Comprehensive Plan Land Use designation for the area
is Residential Rural (RR) and states that open space and natural resources and
environmentally sensitive areas should be preserved and protected by limiting residential
development in critical areas (Objective LU-I). Low density residential development (1
du/acre) should be permitted in areas with significant environmental constraints,
including steep slopes (Policy LU-26).
Proposed utility lines would not result in higher density residential development in the RR
designated area. Minimal clearing of vegetation would occur within the 20-foot wide
utility corridor in order to install the storm water line above ground. More extensive
clearing within the 20-foot wide corridor would need to be accomplished to install the
sanitary sewer line below ground in accordance with State Department of Ecology
regulations. The proposed corridor is a designated greenbelt due to steep slopes. No
wetland or wetland buffers appear to be located within the proposed corridor. The
applicant's wetlands biologist has visited the site with instructions to delineate wetlands
in the corridor. None were found during the November, 1997 visit.
(2) ZONING CODE
The Residential - 1 Dwelling Unit per Acre (R-1) Zone (Section 4-31-4) permits single
family residential development at low densities. Small utilities are also permitted as a
primary use. The proposal complies with permitted uses and applicable development
standards of the R-1 Zone.
(3) GREENBELT REGULATIONS
The Greenbelt Regulations (Code Section 4-31-35) guides development activities
allowed greenbelt areas. Utilities are permitted with the approval of a Conditional Use
Permit. The proposal to construct a sanitary sewer line and storm sewer line within a 20-
foot wide utility corridor,would result in the removal of vegetation on the slope within the
greenbelt. The applicant has proposed minimal disturbance of vegetation by installing
both utility lines on the surface of the slope. However, State Department of Ecology
(DOE) does not allow wastewater lines to be installed above ground. Clearing and
digging would be required to construct the sewer line at the appropriate depth required
by DOE. A stormwater and wastewater stub connection was installed in the abutting
Springbrook Condominium development to the west, and the Talbot Ridge plat would tie
into that stub.

(5B) COMMUNITY NEED:
There shall be a community need for the proposed use at the proposed location. In the
determination of community need, the Hearing Examiner shall consider the following factors,
among all other relevant information:
(a) The proposed location shall not result in either the detrimental over concentration of a
particular use within the City or within the immediate area of the proposed use.
Two utility systems to serve the plat would be located within the greenbelt. Both
stormwater and sanitary sewer would be constructed within a 20-foot wide utility
easement that would traverse the slope to connect with existing stormwater and
wastewater stubs in the Springbrook Condominiums project to the west. The remainder
of the greenbelt area would be undisturbed.
(2) That the proposed location is suited for the proposed use.
A utility stub connection exists on the abutting property to the west (4700 block of Talbot
Road South). Eventual development of the parcel to the east was anticipated during the
design and construction of the Springbrook Residential community, and the stub-out was
installed to connect with the Talbot Ridge parcel.
(5C) EFFECT ON ADJACENT PROPERTIES:
The proposed use at the proposed location shall not result in substantial or undue adverse
effects on adjacent property. The following site requirements shall be required:
(1) Lot Coverage: Lot coverage shall conform to the requirements of zone in which the
proposed use is to be located.
Not applicable
(2) Yards: Yards shall conform to the requirements of the zone in which the proposed use is
to be located. Additions to the structure shall not be allowed in any required yard.
Not applicable
(3) Height: Building and structure heights shall conform to the requirements of the zone in
which the proposed use is to be located. Spires, belltowers, public utility antennas or
similar structure may exceed the height requirement upon approval of a variance.
Building heights should be related to surrounding used in order to allow optimal sunlight
and ventilation, and minimal obstruction of views from adjacent structures.
Not applicable
(5D) COMPATIBILITY:
The -proposed use shall be compatible with the residential scale and character of the
neighborhood. (Ord 3599, 1-11-82)
Development of utility lines to serve the single family residential plat would be compatible with
the existing and proposed residential scale of the area. Minimal disturbance of the vegetated
slope would occur to construct the utility systems. The applicant proposes to place "hill holders"
or other slope stabilizing mechanisms appropriately throughout the slope to insure stability.
Vegetation would need to be managed over time to provide for maintenance access as needed.
(5E) PARKING:

Parking under the building structure should be encouraged. Lot coverage may be increased to
as much as seventy-five percent(75%) of the lot coverage requirement of the zone, in which the
proposed use is located, if all parking is provided underground or within the structure. (Ord.3903,
4-22-85)
Not applicable
(5F) TRAFFIC:
Traffic and circulation patterns of vehicles and pedestrians relating to the proposed use and
surrounding area shall be reviewed for potential effects on, and to ensure safe movement in the
surrounding area.
Not applicable
(5G) NOISE, GLARE:
Potential noise, light and glare impacts shall be evaluated based on the location of the proposed
use on the lot and the location of on-site parking areas, outdoor recreational areas and refuse
storage areas.
Not applicable
(5H) LANDSCAPING:
Landscaping shall be provided in all areas not occupied by building or paving. The Hearing
Examiner may require additional landscaping to buffer adjacent -properties from potentially
adverse effects of the proposed use.
Not applicable
(5/) ACCESSORY USES:
Accessory uses to conditional uses such as day schools, auditoriums used for social and sport
activities, health centers, convents, preschool facilities, convalescent homes and others of a
similar nature shall be considered to be separate uses and shall be subject to the provisions of
the use district in which they are located.
Not applicable
(5J) CONVERSION:
No existing building or structure shall be converted to a conditional use unless such building or
structure complies, or is brought into compliance, with the provisions of this Chapter.
Not applicable
(5K) PUBLIC IMPROVEMENTS:
The proposed use and location shall be adequately served by and not impose an undue burden
on any public improvements, facilities, utilities, and services. Approval of a conditional use permit
may be conditional upon the provision and/or guarantee by the applicant of necessary public
improvements, facilities, utilities, and/or services.
The proposal is to provide necessary utility systems to adequately serve the proposed plat to the
' east.

PUBLIC HEARING DATE: NOVEMBER 18, 1997 Page 9 of 15
6. CONSISTENCY WITH VARIANCE CRITERIA:
The proposal to remove vegetation on a steep slope in order to construct the storm sewer and
wastewater utility lines would result in the removal of trees and vegetation. The applicant has applied for
a variance from Code Section 4-9-10:C in order to cut trees and clear land in steep slope areas.
City Code Section 4-31-19 F. states that the Hearing Examiner has authority to grant a variance upon
making a determination, in writing, that the conditions specified below have been found to exist:
a. That the applicant suffers undue hardship and the variance is necessary because of special
circumstances applicable to subject property, including size, shape, topography, location or •
surroundings of the subject property, and the strict application of the Zoning Code is found to
deprive subject property owner of rights and privileges enjoyed by other property owners in the
vicinity and under identical zone classification:
The clearing which would occur for the utility lines would tie into the existing Springbrook
development (downslope to the west). This is the only feasible way in which to serve the
proposed Talbot Ridge plat with the necessary storm and sanitary sewer facilities. The subject
site is located adjacent to the Renton/King County boundary, and Renton is the only utility
purveyor with the ability to serve the site with sanitary sewer. No other gravity fed sewer system
option presently exists for the site which is both zoned for and designated in the Comprehensive
,Plan for up to 8 dwelling units per acre.
b. That the granting of the variance will not be materially detrimental to the public welfare or
injurious to the property or improvements in the vicinity and zone in which subject property is
situated:
The developer is proposing to install "hill holders" or other slope stabilizing mechanisms to help
stabilize the slope. This would help insure the utility connection would not be detrimental to the
hillside and would help minimize the impacts to the slope and greenbelt area. All clearing
activities would need to be accomplished in accordance with City codes and policies.
c. That approval shall not constitute a grant of special privilege inconsistent with the limitation upon
uses of other properties in the vicinity and zone in which the subject property is situated:
The portion of the property that would be developed for the residential lots occupies a bluff
overlooking a valley area. Land to the east of the subject site is within King County jurisdiction,
and south is a limited triangular portion of the City of Renton which is designated for single
family residential development at up to 8 dwelling units per acre. Because this property sits at a
higher elevation adjacent to the easterly boundary to the City, the only potential for Renton
sewer service is downhill to the west. Without the sewer connection, the development could
occur, since septic systems are not permitted for new residential development of this density.
Utilities Policy U-56 states that: "All new developments should be required to connect to the
sanitary sewer system, except low density single family residential development located away
from environmentally sensitive areas." There are only a limited number of properties which
require variances for utilities extending westerly through the greenbelt and steep slope areas.
d. That the approval as determined by the Reviewing Official is a minimum variance that will
accomplish the desired purpose:
The proposal is to develop a utility corridor within the steep slope area for an above-ground
storm water pipe and an underground sanitary sewer pipe to serve the Talbot Ridge plat.
Construction within the 20-foot wide utility easement would be the minimum variance needed to
serve the plat with sanitary and stormwater facilities.

TALBOTRIDGEPRELIMINARYPLAT LUA-97-087,PP, CU-H,V,ECF
PUBLIC HEARING DATE: NOVEMBER 18, 1997 Page 10 of 15
7. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA:
Approval of a plat is based upon several factors. The following preliminary plat criteria have been
established to assist decision makers in the review of the plat:
(a) Compliance with the Comprehensive Plan Designation. The proposal is consistent with
the Comprehensive Plan designation of Residential Rural (RR) and Residential - Single Family
(RSF).
(b) Compliance with the Underlying Zoning Designation. The proposal site is designated R-1
and R-8, on the City of Renton Zoning Map. The proposed development would allow for future
construction of up to 19 new dwelling units.
Minimum lot size permitted in both the R-1 and R-8 Zones is 4,500 sf. The proposed
plat provide 19 lots all within the R-8 portion of the project and ranging in size from 4,500 square
feet to 5,642 square feet. These lot sizes are smaller than other existing lots in this area, but
compatible with the R-8 designation that applies to other parcels located south of the subject
site.
The R-8 Zone permits densities of 5.0 dwelling units per net acre minimum to 8.0
dwelling units per acre maximum. Net density is determined by deducting the right-of-way and
sensitive areas from the overall site area. It appears that the 19 lots proposed exceed maximum
density requirements of the R-8 Zone. Based on staff calculations, the applicant would be
permitted a minimum of 12 units or a maximum of 17 units. This calculation could change
based on requirements for dedication of additional right-of-way. In any event, staff will
recommend that the applicant modify the plat to meet the density requirements of the R-8 Zone.
It appears that this modification could occur through the reduction of the number of lots in the
plat. A detailed analysis will be presented during the public hearing.
(c) Compliance with Subdivision Regulations.
Lot Arrangement. Side lot lines are to be at right angles to street lines, and each lot must
have access to a public street or road. Access may be by private access easement
street per the requirements of the Street Improvement Ordinance (Code Section 4-34).
The nineteen proposed lots generally meet the requirements for side lot lines to be at
right angles to streets. The lots proposed for the turning circle of the cul-de-sac are
irregularly shaped and the side lot lines at the frontage intersect the cul-de-sac
somewhat irregularly. However,the intent of the lot arrangement criteria is met.
Lots: The size, shape and orientation of lots shall meet the minimum area and width
requirements of the applicable zoning classification and shall be appropriate for the type
of development and use contemplated.
The proposed parcels would meet minimum size, shape and orientation requirements.
Width and depth requirements are also generally met. Proposed lots Nos. 1 and 6 would
be located both on the new public street (South 47th Street) and the new private street
(Burnett Avenue South). If they are considered to be corner lots, then the width would
need to be adjusted to the minimum 60-foot width requirement. This minor adjustment
could be accomplished by shifting the lot lines slightly for Lots 2/3 and 4/5. This would
be considered to be a minor adjustment. The applicant has indicated the building
envelopes for each of the proposed lots in accordance with the applicable development
standards.
Property Corners at Intersections: All lot corners at intersections of dedicated public
rights-of-way, except alleys, shall have minimum radius of 15 feet.

City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner
TALBOT RIDGE PRELIMINARY PLAT LUA-97-087,PP, CU-H,V,ECF
PUBLIC HEARING DATE: NOVEMBER 18, 1997 Page 11 of 15
The proposal would comply with the minimum radius requirement.
(d) Reasonableness of Proposed Boundaries
Access
The proposal is anticipated to generate up to 181.45 new average daily trips. Access would be
from 102nd Avenue SE, a King County street. This street would be extended north, and a new
east/west public street would be constructed (South 47th Street) to serve the plat. This street
would end in a cul-de-sac. A new private street (Burnett Avenue South) serving up to six lots
(Nos. 1 through 6) would be constructed. Lots 9 and 10 are shown accessing from a tract (Tract
A).
Objective LU-M of the Comprehensive Plan calls for more linkages within and between
neighborhoods by developing a system of residential street which serve both vehicles and
pedestrians and creating a continuous, efficient, interconnected network of roads and pathways
throughout the City. Policy LU-70 states that: "Streets, sidewalks, pedestrian or bike paths in a
neighborhood development should be arranged as an interconnecting network. The extensive or
predominant use of cul-de-sacs and pipestems should be discouraged for new development. A
"flexible grid"pattern of streets and pathways should be used to connect adjacent and future
development." The proposed plat would not provide the interconnecting street system
envisioned by the policies of the Comprehensive Plan. Adjacent parcels would continue to be
landlocked.
Therefore, staff will recommend as a condition of plat approval, that the Talbot Ridge Plat should
be modified to provide dedicated public right-of-way to allow for future access to the
undeveloped properties north and south of the site. The property to the north appears to have
limited development potential due to the R-1 zoning, and the existence of a large pit near this
site. The right-of-way to the north property line will not need to improved at this time, since it is
not possible to determine the number of lots which will be developed to the north, and therefore
the level of street improvements required. This right-of-way must be either 35 feet in width if
provided along the east property line, or 42 feet in width if provided within the plat boundaries.
The property to the south clearly has the potential for development of 20 to 30 parcels. This
right-of-way, and related street improvements may be provided in one of two ways:
1. Provide for half street improvements along the east property line, with 35 feet of
dedicated right-of-way, 28 feet of pavement, sidewalk and curb along the west side of
the street and street lighting, or
2. Provide 42 feet of right-of-way within the plat boundaries, with a fully developed 32
feet of pavement,with curb and sidewalks along both sides, and street lighting.
The rest of street improvements for the plat (South 47th Street and 102nd Avenue SE) have
been analyzed by City staff and are acceptable as shown on the preliminary plat submittals. The
Fire Department, in consultation with the Planning/Building/Public Works Department
Department, granted a modification to the dead-end street length to allow for a system which
exceeds 700 feet in length. This modification was granted based on the conditions of providing a
full 32 feet pavement width for the entire length of the single access to the plat, along with a
sidewalk along one side of this off-site street improvement. Additionally, all the houses within
the new plat must be constructed with sprinkler systems. This wider street section (standard
code requirement for off-site width is 20 feet minimum) will allow for reliable access for
emergency vehicles,with adequate room to get around any blocking vehicles within the roadway.
City street standards (Section 4-34-5D) do not permit the construction of a private street if the
adjacent property needs to be served. The private street serving Lots 1 - 6 (Burnett Avenue
South) would not be acceptable as depicted. The applicant would need to demonstrate an
HEXRPT.DOC

PUBLIC HEARING DATE: NOVEMBER 18, 1997 Page 12 of 15
appropriate connection to the abutting south parcel with a public street. Either the private street
would need to be revised to a public right-of-way width, or an additional public street right-of-way
would need to be proposed to the south.
In addition, Tract A, shown serving Lots 9 and 10 would not be permitted. However, this tract
could be incorporated into either of the lots as a pipestem, provided the other lot was granted an
access easement. This would be a minor modification for the proposed plat.
Topography
The site slopes from east to west. Severe slopes of up to 70% are present on the western one-
half of the property. This area is designated as greenbelt by the City, and zoned for low density
residential development (R-1). No development of building lots is proposed in the greenbelt
area/R-1 portion of the site.
Low to moderate slopes (less than 10%) are found on the easternmost parcels -- proposed lots
No. 1 through 8 and 16 through 19. The westernmost parcels- Lots 8 through 15 have slopes of
up to 20%. Additional geotechnical studies for the western portion of the site were required as a
mitigation measure. According to the applicant, the studies have not resulted in additional
recommendations affect how the lots could be developed.
City Code limits maximum driveway slope for single family residential uses to 15% (Code
Section 4-14-4:B.7.a). The applicant would need to provide slotted drains at the lower end of
driveways exceeding 8% slope, with positive drainage discharge to restrict runoff from entering
the garage/residence or crossing any public street.
Relationship to Existing Uses
The project site is presently vacant. Access and utility constraints have kept the parcel from
developing until now. This area is at the boundary of King County and City of Renton.
Development is occurring within the City of Renton to the west, along Talbot Road South. These
sites have zoning which permits higher densities than proposed here. Adjacent parcels on the
top of the plateau are typically undeveloped and are from one to five acres, unless subdivision
has taken place under King County. Fredericks Place, a subdivision east of 102nd Avenue SE
and SE 186th has lots that are generally 6,000 to 7,000 square feet in size, with larger
undeveloped open space tracts.
The proposal would differ from the existing residential uses surrounding it, but only for such time
that those parcels remain undeveloped or underdeveloped based on current zoning. The steep
slope and wetland areas on the slopes are zoned for low intensity residential uses (1 unit per
acre) and would not be developed in the foreseeable future.
(e) Availability and Impact on Public Services(Timeliness)
Police and Fire
Police and Fire Prevention Bureau staff indicate that sufficient resources exist to furnish services
to the proposed development, subject to the condition that the applicant provide Code required
improvements and fees.
Recreation
The proposal would impact the local park and recreation facilities, however, no further conditions
would be required to off-set those impacts, provided that the applicant pays the required Park
Mitigation Fee.

Schools
The Renton School District was contacted regarding the proposal to construct 19 lots suitable for
single family residences. A response was received and the School District indicated that they
would be able to accommodate the additional students such a development would generate.
The students would attend Renton Park Elementary, Nelsen Middle School or Lindbergh High
School.
Storm water
Stormwater would be collected by a tightline conveyance system and routed to conveyed to an
underground detention vault. The vault would be constructed at the top of the slope, west of
proposed lots 10, 11, and 12. From there, the stormwater would be tightlined downslope to the
west, and tie into an existing stub in the Springbrook Condominium development. Talbot Road
South is developed with a system of stormwater ditches. Runoff from 0.44 acre of frontage
improvements would be conveyed to the onsite detention facility. Runoff from the remaining
frontage improvements would be conveyed to a detention pipe which would discharge into an
existing swale.
There has been localized flooding in the area. The City's Environmental Review Committee has
required that additional stormwater detention-through the 100-year storm event- be provided to
minimize the stormwater drainage impacts presently occurring downstream.
Water and Sanitary Sewer Utilities
Talbot Ridge Plat would be served by Soos Creek Water District. A Certificate of Water
Availability from the Soos Creek Water and Sewer District has been provided as part of the plat
application. Soos Creek does not have sewer facilities serving this property.
City of Renton would provide sanitary sewer service. The applicant has proposed to tie into an
existing wastewater connection at the common property boundary between the Springbrook
Condominiums and Talbot Ridge Plat. Adequate capacity exists in the City's system to
accommodate the proposed 19 lots.
Street Improvements:
The proposal would result in the extension of an existing County street (102nd Avenue SE) and
the construction of a new public street (South 47th Street) and private street (Burnett Avenue
South). The parcel would be landlocked without this street extension. Since the proposal is
more than 700 feet from a secondary point of access, the Renton Fire Department is requiring
that the proposed street(South 47th Street) be constructed at full City right-of-way standards- 50
feet in width. In addition, all of the homes within the plat will be required to have fire sprinklers.
City Code permits the construction of new private streets only if the proposed private street is not
anticipated by the Department to be necessary for existing or future traffic and/or pedestrian
circulation though the subdivision or to serve the adjacent property. Since adjacent properties
are landlocked, a recommended condition of plat approval will be for the extension of a public
street north and south. Improvements in the form of curb, gutter, sidewalks and street lighting
would be required for the southerly extension. Dedication would be required for the northern
extension, but improvements would not be required.
South 47th Street would need to meet City street standards for curb, gutter, sidewalk and street
lighting.

LOCATION OF PROPOSAL: 600 feet east of 102nd Avenue SE and SE 184th
Advisory Notes to Applicant:
The following notes are supplemental information provided in conjunction with the environmental
determination. Because these notes are provided as information only, they are not subject to the appeal
process for environmental determinations. .
Plan Review- Transportation
1. New curb, gutter, sidewalk, driveways, street paving and street lighting will be required per City Code/Standards.
2. A traffic mitigation fee of$75.00 per each new single family residence will be required. The fee is discussed in the
mitigation measures and is estimated to be $13,608.75 (9.55 trips x 19 new homes= 181.45 new daily trips x$75.00 per
trip= $13,608.75). The fee is due prior to recording of the plat.
3. The access to the site (proposed to run through the State of Washington property)would need to be dedicated to the
City of Renton. The right-of-way would need to be a minimum of 50 feet in width to meet minimum City design
standards.
4. City Code limits maximum driveway slope to 15%; provided that slopes exceeding 8% shall provide slotted drains at
the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any public
sidewalk. If any proposed driveways exceed 15%,then the applicant would need to seek a variance.
Plan Review-Water
5. The site will be served by the Soos Creek Water District. The water system must meet Renton Fire Department
Standards/Regulations and the current Fire Code. Fire hydrants will need to supply 1,000 gallons per minute. Any
system development charges needed for the water system should be paid to and per the requirements of the Soos Creek
Water District.

TO: Jennifer Toth Henning
FROM: Bob Mac Onie
SUBJECT: Talbot Ridge Preliminary Plat No.,LUA-97-087-PP
Initial Review
I have reviewed the above referenced preliminary plat submittal and have the following comments:
The 50' right-of-way extending into the site is apparently not part of the property under plat and •
therefore will require separate approval of the dedication. It may be possible to have council act on it
concurrently if it is specifically noted as a spearate dedication.
N-Information needed forfinal plat approval includes the following:
Show ties to the City of Renton Survey Control network.network.—See-attaolietl.
The geometry will be checked when the ties have been provided.
Provide plat and lot closure calculations.
Note discrepancies between bearings and distances of record and those measured or calculated,if any.
Note the ity's land use action number (LUA-97-XXX-FP) and the city's land record number (LND-
10-032yron the drawing, preferably in the upper right-hand corner. The type size used for the land
record number should be smaller than that used for the land use action number. Please note that the
land use action number for the final plat is different from the preliminary plat number and is unknown
as of this date.
The owner(s) of the property needs to sign the final lot document(include notary blocks as required).
Include a dedication/certification block on the drawing.
Required signature blocks are: (1) City of Renton Administrator of Planning, Building and Public
Works, (2) City of Renton Mayor, (3) City of Renton City Clerk, and (4) City of Renton Director of
Finance,Department of Finance. The appropriate King County approvals are also needed.
The addresses for the proposed lots will be sent under separate.cover.
V
Include the basis of bearing,per WAC 332-130-050 1.b.iii.
Include a statement of equipment and procedures used,per WAC 332-130-100.
September 15, 1997
Page 2
Indicate what is,or has been,set at the corners of the proposed lots.
Note the date the existing monuments were visited, per WAC 332-130-150-1:f.iv., and what was
found.
Note to whom the new easements are to be granted(private or City-held).
Note thatj( there are easements, restrictive covenants or agreements, to others, as part of this
subdivision, they can be recorded concurrently with the plat. The plat drawing and the associated
document(s) are to be given to the City Clerk's Office as a package. The plat shall have the first
recording number. The recording number(s) for the associated document(s) will be referenced on the
plat in the appropriate location(s).
"(new easements, like the access easement, are shown for the benefit of future owners of the proposed
lots, then include the following statement on the drawing,juxtaposed to the subject easements: "Area
reserved for private exclusive easement for to be created upon the sale of the lots
shown on this plat." Since the lots created via this plat are under common ownership at the time of
recording, there can be no easement until such time as ownership of one, or more, of the lots is
conveyed to others,together with and/or subject to specific easement rights.
Because this property is located within Zone 2 of Renton's Aquifer Protection Area, the Aquifer
Protection Notice needs to be noted on the drawing. See attached.
An updated Plat Certificate , dated within 45 days of Council action on the approval of the plat, is
needed.
Complete City of Renton Monument Cards,with reference points for new right-of-way monuments.
The surveyor needs to stamp,sign and date the drawings before recording.

MEMORANDUM
DATE: NOVEMBER 6, 1997
TO: JENNIFER HENNING
FROM: NEIL WATTS
SUBJECT: - ADDITIONAL STREET IMPROVEMENT REQUIREMENTS
TALBOT RIDGE PLAT
The Talbot Ridge Plat should be modified to provide dedicated public right-of-way to allow for
future access to the undeveloped properties north and south of the site. The property to the north
appears to have limited development potential due to the R-1 zoning, and the existence of a large
pit near this site. The right-of-way to the north property line will not need to improved at this
time, since it is not possible to determine the number of lots which will be developed to the north,
and therefore the level of street improvements required. This right-of-way must be either 35 feet
in width if provided along the east property line, or 42 feet in width if provided within the plat
boundaries.
The property to the south clearly has the potential for development of 20 to 30 parcels. This
right-of-way, and related street improvements may be provided in one of two ways:
1. Provide for half street improvements along the east property line, with 35 feet of dedicated
right-of-way, 28 feet of pavement, sidewalk and curb along the west side of the street and street
lighting, or
2. Provide 42 feet of right-of-way within the plat boundaries, with a fully developed 32 feet of
pavement, with curb and sidewalks along both sides, and street lighting.
The rest of street improvements for the plat are acceptable as shown on the preliminary plat
submittals. The Fire Department, in consultation with the PBPW Department, granted a
modification to the dead-end street length to allow for a system which exceeds 700 feet in length.
This modification was granted based on the conditions of providing a full 32 feet pavement width
for the entire length of the single access to the plat, along with a sidewalk along one side of this
off-site street improvement. Additionally, all the houses within the new plat must be constructed
with sprinkler systems. This wider street section (standard code requirement for off-site width is
20 feet minimum) will allow for reliable access for emergency vehicles, with adequate room to get
around any blocking vehicles within the roadway.

POLICE RELATED COMMENTS
14.06 Police Calls for Service Estimated Annually
CONSTRUCTION PHASE
Theft from construction sites is one of the most common reported crimes in the city. To
protect materials and equipment it is recommended that all materials and tools be locked
up when not in use. The site will need security lighting and any construction trailer should
be fenced in with portable chain-link fencing. The fence will provide both a physical and
psychological barrier to any prospective thief and will demonstrate that this area is private
property.
COMPLETED BUILDINGS
The single-family residences should have solid core doors, preferably metal or metal over
solid wood with peep holes and heavy-duty dead bolt locks. The bolts need to be at least
1-1/2" in length when extended and installed with 3"wood screws.
Sliding windows, including the glass patio doors,will need additional locks;these locks
will need to secure the windows from being pried out of the frames vertically. This means
the locks will need to be placed into the top or bottom of the frames, in addition to any
lock that limits horizontal movement.
Any stairways should be constructed of lattice or metal railing so visibility is possible.
There should not be any solid walls in any stairway that would serve to limit the visibility
up and down the stairs and provide a place for a criminal to hide while waiting for a
homeowner to return home. In addition, any fencing around the homes should be made of
• either metal or wood lattice or railing-no solid fencing for the same reason.
The homes should have the addresses listed clearly,with numbers at least 6" in height, of a
color that contrasts with the color of the homes, and placed under a light. This will aid
police or medics who respond to a call in finding the address that they need to go to.
Landscaping around the exterior of the property should not be too dense or high. It is
important to allow visibility. Too much landscaping will give the property the look of a
fortress and make the homeowner feel isolated, and could also possibly give a burglar
sufficient coverage to break into the residences.
Theft from motor vehicle is one of the most common occuring crimes in this city. It is
important that sufficient street lighting be provided leading to each home, as well as for
any outside parking.

PLANNING/BUILDING/PUBLIC WORKS DEPARTMENT
MEMORANDUM
DATE: NOVEMBER 6, 1997
TO: JENNIFER HENNING
FROM: NEIL WATTS
SUBJECT: ADDITIONAL STREET IMPROVEMENT REQUIREMENTS
TALBOT RIDGE PLAT
The Talbot Ridge Plat should be modified to provide dedicated public right-of-way to allow for
future access to the undeveloped properties north and south of the site. The property to the north
appears to have limited development potential due to the R-1 zoning, and the existence of a large
pit near this site. The right-of-way to the north property line will not need to improved at this
time, since it is not possible to determine the number of lots which will be developed to the north,
' , and therefore the level of street improvements required. This right-of-way must be either 35 feet
in width if provided along the east property line, or 42 feet in width if provided within the plat
boundaries.
The property to the south clearly has the potential for development of 20 to 30 parcels. This
right-of-way, and related street improvements may be provided in one of two ways:
1. Provide for half street improvements along the east property line, with 35 feet of dedicated
right-of-way, 28 feet of pavement, sidewalk and curb along the west side of the street and street
lighting, or
2. Provide 42 feet of right-of-way within the plat boundaries, with a fully developed 32 feet of
pavement, with curb and sidewalks along both sides, and street lighting.
The rest of street improvements for the plat are acceptable as shown on the preliminary plat
submittals. The Fire Department, in consultation with the PBPW Department, granted a
modification to the dead-end street length to allow for a system which exceeds 700 feet in length.
This modification was granted based on the conditions of providing a full 32 feet pavement width
for the entire length of the single access to the plat, along with a sidewalk along one side of this
off-site street improvement. Additionally, all the houses within the new plat must be constructed
with sprinkler systems. This wider street section (standard code requirement for off-site width is
20 feet minimum) will allow for reliable access for emergency vehicles, with adequate room to get
around any blocking vehicles within the roadway.

DESCRIPTION OF PROPOSAL: The applicant,Triad Associates, proposes to subdivide 4.55 acres of a vacant site into
19 lots for single family homes. The site is zoned R-1 and R-8. Project requires environmental review, preliminary plat approval,
conditional use permit and variance to construct storm sewer lines in a steep slope/greenbelt area. A new street would be
extended from 102nd Avenue SE to serve the plat.
LOCATION OF PROPOSAL: 600 feet east of 102nd Avenue SE and SE 184th
Advisory Notes to Applicant:
The following notes are supplemental information provided In conjunction with the environmental
determination. Because these notes are provided as Information only, they are not subject to the appeal
process for environmental determinations.
Plan Review- Transportation
1. New curb, gutter, sidewalk, driveways, street paving and street lighting will be required per City Code/Standards.
2. A traffic mitigation fee of$75.00 per each new single family residence will be required. The fee is discussed in the
mitigation measures and is estimated to be $13,608.75 (9.55 trips x 19 new homes= 181.45 new daily trips x$75.00 per
trip= $13,608.75). The fee is due prior to recording of the plat.
3. The access to the site (proposed to run through the State of Washington property)would need to be dedicated to the
City of Renton. The right-of-way would need to be a minimum of 50 feet in width to meet minimum City design
standards.
4. City Code limits maximum driveway slope to 15%; provided that slopes exceeding 8% shall provide slotted drains at
the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any public
sidewalk. If any proposed driveways exceed 15%,then the applicant would need to seek a variance.
Plan Review-Water
5. The site will be served by the Soos Creek Water District. The water system must meet Renton Fire Department
Standards/Regulations and the current Fire Code. Fire hydrants will need to supply 1,000 gallons per minute. Any
system development charges needed for the water system should be paid to and per the requirements of the Soos Creek
Water District.
Plan Review-Surface Water
6. Drainage system and temporary erosion control plans for the site shall be designed in accordance with the 1990 King

TALBOT RIDGE PRELIMINARY PLAT LUA-97-098,PP,CU-H,V ECF
REPORT OF OCTOBER 20,1997 Page2 of 8
The applicant proposes to subdivide 4.55 acres of a vacant site into 19 lots suitable
Project Description for the development of single family residential homes. The resulting parcels would
range in size from 4,500 square feet to 5,642 square feet. A new public street would
be extended from 102nd Avenue SE to serve the plat. Approximately 980 lineal feet
of the new 50-foot wide right-of-way street would be located off-site, on land
presently owned by the State of Washington. Of this, 700 lineal feet would be within
the City of Renton, and 280 feet would be the extension of 102nd Avenue S.E., a
King County street. A 26-foot wide private street would provide access to new lots
Nos. 1 through 6, although Lots 1 and 6 would also have access to the new public
street. An access easement would provide vehicular access to new Lots No. 9 and
10 from the cul-de-sac of the public street.
Development would occur on approximately 2.7 acres of a 4.55 acre site. The new
parcels would be created on the eastern half of the site, which is zoned Residential-
8 dwelling units per acre (R-8). The western half is zoned R-1 due to the steep
slopes. Only the construction of a sanitary sewer line, stormwater detention vault,
and stormwater conveyance facilities is proposed to occur on the western portion of
the property.
A site-specific wetland investigation report was prepared to determine whether
wetland habitat was present in the off-site area proposed for the public right-of-way.
The report determined that an unclassified steam flows from south to north through
the area of the proposed road. The area is partially within the jurisdiction of both the
City of Renton and King County. A small wetland was identified associated with the
stream. The delineated wetland exists within the stream corridor and the delineated
area is approximately 1,800 square feet in size. Most of the riparian area existing
within King County's jurisdiction. According to the King County Sensitive Areas
Ordinance,the riparian area of the stream would be rated a Class 3 because of it's
small size and limited habitat. The stream is not rated by the City of Renton, and
could be rated Class 3 because it is seasonal and does not support salmonid fish
species. The stream is mapped as a tributary to Panther Creek, located to the north.
Construction of the proposed right-of-way would result in the placement of fill and
culverting of an area of approximately 9000 square feet. Half of this impacted area
would be within King County, and the remainder in Renton.
The site is zoned both R-1 and R-8. The proposal requires environmental review,
preliminary plat approval, conditional use permit and a variance to construct storm
sewer lines in a steep slope/greenbelt area.

unit. The required mitigation fee shall be paid prior to the recording of the plat.
6. The applicant shall pay the appropriate Fire Mitigation Fee equal to $488 per single family residential lot. The
Fire Mitigation Fee is payable prior to the recording of the plat.
Advisory Notes to Applicant:
The following notes are supplemental information provided in conjunction with the environmental
determination. Because these notes are provided as information only, they are not subject to the appeal
process for environmental determinations.
Plan Review-Transportation
1. New curb, gutter, sidewalk, driveways, street paving and street lighting will be required per City Code/Standards.
2. A traffic mitigation fee of$75.00 per each new single family residence will be required. The fee is discussed in the
mitigation measures and is estimated to be $13,608.75 (9.55 trips x 19 new homes= 181.45 new daily trips x$75.00
per trip= $13,608.75). The fee is due prior to recording of the plat.
3. The access to the site (proposed to run through the State of Washington property)would need to be dedicated to
the City of Renton. The right-of-way would need to be a minimum of 50 feet in width to meet minimum City design
standards.
4. City Code limits maximum driveway slope to 15%; provided that slopes exceeding 8% shall provide slotted drains
at the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any
public sidewalk. If any proposed driveways exceed 15%, then the applicant would need to seek a variance.
Plan Review-Water
5. The site will be served by the Soos Creek Water District. The water system must meet Renton Fire Department
Standards/Regulations and the current Fire Code. Fire hydrants will need to supply 1,000 gallons per minute. Any
system development charges needed for the water system should be paid to and per the requirements of the Soos
Creek Water District.

family structures exceed 3,600 square feet total floor area (including garage and basements).
10. The fire mitigation fees are applicable at the rate of$488 per single family building: 19 single family units x
$488.00 = $9,272.00. The fire mitigation fees are discussed under the mitigation measures. The fee is due prior to
recording of the plat.
11. An approved fire sprinkler system is required to be installed throughout all the structures. All building shall have
the sprinkler system monitored by an approved alarm company.
12. The fire main serving this subdivision shall be looped to the supply serving the existing residential building fire

REPORT OF OCTOBER 20,1997 Page5 of 8
D. ENVIRONMENTAL IMPACTS
In compliance with RCW 43.21 C. 240, the following project environmental review addresses only
those project impacts that are not adequately addressed under existing development standards and
environmental regulations.
Has the applicant adequately identified and addressed environmental impacts anticipated to occur in
conjunction with the proposed development?
1. Earth
Impacts: The proposed development of new lots would be limited to the eastern half of the site (approximately 2.7
acres), in order to avoid construction within the steep slope area on the west. The ground surface on the west portion
of the site slopes approximately 7.5% (west to east). The west half has slopes that are approximately 70%. Slopes
on individual parcels would not exceed 20% and the steeper slopes would b for lots abutting the west edge.
Clearing and grading on the east part of the site would be necessary in order to create streets, install utilities, and
develop building pads. The applicant has not provided estimates for the amount of material that would be cut and
either exported or reused as fill on the site, or for the amount of material of fill thatwould be imported for the
construction of roads, building pads, and site improvements.
A subsurface exploration and preliminary geotechnical engineering report prepared by Associated Earth Sciences,
Inc. (AES)was submitted with the project application. This analysis was specifically to determine the engineering
feasibility for proposed stormwater detention vault on the subject site. The report determined that the vault could be
constructed using a conventional, shallow, foundation and retaining walls,without.a significant adverse impact on
slope stability.: No soils report or geotechnical recommendations were provided with regard to the construction
methods or appropriate setbacks from the steep slope area to the west. The applicant will be required to submit a
supplemental geotechnical report which specifies recommendations for appropriate construction methods and
setbacks from slopes for the homes which would be constructed in the plat.
A supplemental letter was submitted by AES regarding the liquefaction potential at the subject site. The letter
concluded that based on subsurface data from the geotechnical study, and knowledge of the regional geology and
ground water conditions,that their interpretation is that the risk of seismic induced liquefaction on the site is low,
which would not require mitigation measures.
Mitigation Measures: The applicant shall follow the recommendations of the geotechnical engineering study as
prepared for the Talbot Ridge Preliminary Plat by Associated Earth Sciences, Inc. In addition,the applicant will be
required to submit a supplemental geotechnical report which specifies recommendations for appropriate construction
methods and setbacks from slopes for the homes which would be constructed in the plat.
Nexus: Environmental (SEPA) Ordinance (Section 4-6)
2. Air
Impacts: Impacts to air quality can be anticipated during construction and after occupancy of the proposed project.
Impacts during construction would include increased levels of airborne particulates (especially dust) from disturbance
of exposed soils. Construction impacts would be short term in nature and would be mitigated through best
management practices of the required Temporary Erosion/Sedimentation Control Plan and with the Construction
Mitigation Plan. Emissions from construction equipment exhaust would have a minor impact on local air quality.
Exhaust from construction vehicles is regulated by State and City Codes. After construction the impacts would be
associated primarily with vehicle exhaust from resident traffic. Vehicle emissions are regulated by the State of
Washington. Overall,air impacts would be relatively minor in nature and not considered significant to warrant special
mitigation measures.
Mitigation Measures: No further mitigation required.

REPORT OFOCTOBER 20,1997 Page6 of 8
3. StormWater
Impacts: The stormwater runoff generated from the project site including roads, dirveways, and roofs would be
collected in a series of catch basins,and routed to a detention system constructed on-site. The stormwater would be
released as a control rate not to exceed that of the post development rate for the 2, 10, and 100-year/24 hour storm
events. The detention outfall would be tightlined along the southerly property line, and would tie into the storm system
of Talbot Park located west of the subject site. In addition of this,there would be a separate detention system for the
construction of the off-site access roadway. This detention system would discharge water flows into the wetland.
Localized flooding presently occurs downstream from the subject parcel. Additional upstream development would
worsen the existing downstream flooding as the amount of impervious surface would increase. The project would
meet current Code requirements for stormwater facilities, but would still contribute to the off-site flooding, unless
additional detention is provided.
Mitigation Measures: The applicant shall be required to provide additional detention of stormwater through the 100-
year storm event, in order to minimize stormwater drainage impacts presently occurring downstream.
Nexus: Environmental Ordinance SEPA(4-6)
4. Transportation
Impacts: The proposed preliminary plat development would result in an increase in traffic trips on the local street
system and therefore would be subject to the City's Transportation Mitigation Fee. The trip generation values are
based on the ITE Trip Generation Manual which estimates 9.55 average daily trips per single family residence, or a
total of 181.45 new average daily trips for the 19-lot development. The Transportation Mitigation Fee is calculated to
be$75 per average daily trip attributable to the project. The traffic mitigation fee is estimated to be$13,608.75 and
would need to be paid prior to the recording of the plat.
The applicant has indicated that construction hauling would occur during the hours of 7:00 am to 9:00 pm Monday
through Friday, and if necessary, 9:00 am to 5:00 pm Saturday and Sunday. City Code precludes site construction on
weekends, except construction on Saturdays may occur with special permission. The applicant would need to revise
the construction mitigation plan to restrict construction-related traffic to off-peak hours between 8:30 a.m. and 3:30
p.m., unless approved in advance by the Development Services Division.
Mitigation Measures: The applicant shall pay the applicable Transportation Mitigation Fee, at a rate of$75.00 per
each new average daily trip attributable to the project. The fee is payable prior to the recording of the plat.
The applicant would need to revise the construction mitigation plan to restrict construction-related traffic to off-peak
hours between 8:30 a.m. and 3:30 p.m., unless approved in advance by the Development Services Division.
Nexus: Transportation Mitigation Fee Resolution and adopting ordinance; Environmental Ordinance (SEPA) 4-6.
5. Wetlands and Streams
Impacts: A swale and wetland are present off-site in the location proposed for the site access road. The new 50-foot
wide public street would require the import of fill material and the installation of culverts to pipe the existing stream
under the proposed road. The stream and wetland area in the stream swale are located within both the City of Renton
and King County. The stream is not classified by the City and is considered to be a Class III stream by King County.
The wetland area would be considered to be a Category 3 wetland by the City. Filling of the approximately 900
square feet of wetland area is proposed, and the wetland report suggests that the impact can be mitigated through the
restoration of disturbed areas with native wetland and riparian species. According to the City's Wetlands Ordinance,
a hydrologically isolated Category 3 wetland of less than 5,000 square feet within a property boundary is exempt from
the requirements of the Ordinance.
Mitigation Measures: No further mitigation required.

6. Parks and Recreation
Impacts: The proposal would allow for the construction of 19 detached single family residential units. Future
residents would make use of the existing and future City park and recreation facilities throughout the City. In order to
mitigate the impact of the development on the City's parks and recreation facilities the City has adopted a mitigation
fee of$530.76 per each new single family residence. The fee would be payable prior to recording of the plat.
Mitigation Measures: The applicant shall pay a Park's Department mitigation fee of$530.76 per each new single
family dwelling unit. The required mitigation fee shall be paid prior to the recording of the plat.
Nexus: Parks Mitigation Fee Resolution, Environmental Ordinance (SEPA) 4-6.
7. Fire and Police Services
Impact: The proposal would add new construction to the City and would potentially impact the City's Fire Department.
A Fire Mitigation Fee would apply to all new construction at a rate of$488 per each new single family unit, for an
estimated total of$9,272.00 (19 lots X$488 = $9,272). The Fire Mitigation Fee is payable prior to the recording of the
plat.
Mitigation Measures: The applicant shall pay the appropriate Fire Mitigation Fee equal to $488 per single family
residential lot. The Fire Mitigation Fee is payable prior to the recording of the plat.
Nexus: Fire Mitigation Fee Resolution and adopting ordinance, Environmental Review(SEPA)
8. Vegetation
Impacts:. The applicant has submitted a preliminary grading plan which depicts trees that would be saved and those
that would be removed for construction of the project. Trees on the wooded west slope would not generally be
disturbed, except to install the stormwater detention vault and wastewater utility line. The grading plan shows five fir
trees and approximately five maple trees that would be retained on the edges of the site. Mass grading for the
proposal would result in the removal of all site vegetation within the clearing limits. Since the proposed parcels are
generally 4,500 square feet to 5,500 square feet, the construction of access, building pads and installation of utilities
would impact the majority of the trees on the eastern 2.7 acres of the site. In order to mitigate this impact, staff will
recommend during the preliminary plat hearing that the applicant be required to establish a Native Growth Protection
Easement for the steep hillside area.
Mitigation Measures: No additional mitigation measures required.

Dear Mr. Guest: •
We understand that the City of Renton has expressed concerns regarding seismic liquefaction
potential at the subject site.
The. explorations completed for Associated Earth Sciences, Inc.'s (AESI's) June 20; 1997
Subsurface Exploration and Preliminary Geotechnical Engineering Report for this project generally
encountered loose grading to medium stiff, or medium dense sand, silt and gravel. These
sediments were interpreted as glacial outwash. No ground water was encountered in any of the
three exploration.holes dug for this study, nor were any evidence of seepages or hillside springs
noted during our geologic:reconnaissance of the hillside. With the possible exception of localized
perched ground water during and after periods of heavy precipitation, it is our interpretation that
there are no adverse ground water conditions in the vicinity of the proposed detention vault.
Based on this subsurface data from our geotechnical study, and our knowledge of the regional
geology and ground water conditions,• it is our interpretation'that the risk of seismic induced
liquefaction on this site is low, and that no mitigating measures for liquefaction are necessary.

MEMORANDUM

TO: Jennifer Toth Henning
FROM: Bob Mac Onie
SUBJECT: Talbot Ridge Preliminary Plat No.,LUA-97-087-PP
Initial Review
I have reviewed the above referenced preliminary plat submittal and have the following comments:
The 50' right-of-way extending into the site is apparently not part of the property under plat and
• therefore will require.separate approval of the dedication. It may be possible to have council act on it
concurrently if it is specifically noted as a spearate dedication.
-Information needed forfinal plat approval includes the following:
Show ties to the City of Renton Survey Control network.—geeasked.
The geometry will be checked when the ties have been provided.
Provide plat and lot closure calculations.
Note discrepancies between bearings and distances of record and those measured or calculated,if any.
Note the ity's land use action number (LUA-97-XXX-FP) and the city's land record number (LND-
10-032on the drawing, preferably in the upper right-hand corner. The type size used for the land
record number should be smaller than that used for the land use action number. Please note that the
land use action number for the final plat is different from the preliminary plat number and is unknown
as of this date.
The owner(s) of the property needs to sign the final lot document(include notary blocks as required).
Include a dedication/certification block on the drawing.
Required signature blocks are: (1) City of Renton Administrator of Planning, Building and Public
Works, (2) City of Renton Mayor, (3) City of Renton City Clerk, and (4) City of Renton Director of
Finance, Department of Finance. The appropriate King County approvals are also needed.
The addresses for the proposed lots will be sent under separate cover.
Include the basis of bearing,per WAC 332-130-050 1.b.iii.
Include a statement of equipment and procedures used,per WAC 332-130-100.

Page 2
Indicate what is, or has been, set at the corners of the proposed lots.
Note the date the existing monuments were visited, per WAC 332-130-150-1.f.iv., and what was
found.
Note to whomthe new easements are to be granted(private or City-held).
Note that there are easements, restrictive covenants or agreements, to others, as part of this
subdivision, they can be recorded concurrently with the plat. The plat drawing and the associated
document(s) are to be given to the City Clerk's Office as a package. The plat shall have the first
recording number. The recording number(s) for the associated document(s) will be referenced on the
plat in the appropriate location(s).
Ifnew easements, like the access easement, are shown for the benefit of future owners of the proposed
lots, then include the following statement on the drawing,juxtaposed to the subject easements: "Area
reserved for private exclusive easement for to be created upon the sale of the lots
shown on this plat." Since the lots created via this plat are under common ownership at the time of
recording, there can be no easement until such time as ownership of one, or more, of the lots is
conveyed to others,together with and/or subject to specific easement rights.
Because this property is located within Zone 2 of Renton's Aquifer Protection Area, the Aquifer
Protection Notice needs to be noted on the drawing. See attached.
An updated Plat Certificate , dated within 45 days of Council action on the approval of the plat, is
needed.
Complete City of Renton Monument Cards, with reference points for new right-of-way monuments.
The surveyor needs to stamp,sign and date the drawings before recording.

Response to September 26, 1997 Memo
Bob Mac Onie and I have reviewed the above referenced drawings and have no comments concerning
the zoning and subdivision requirements imposed on the applicant.
However, we noted that the street name was changed to SE 183rd Place on the revised submittal (the
first submittal reviewed named the subject street South 47th Court). This street is within the City of
Renton city limits and should therefore be named SE 47th Street (per Jan Conklin). In addition, note
that the 26' private access over Lots 1 through 6, inclusive, has been given a name (Burnett Avenue
South). See the attachment for a complete overview of street names and addresses pertaining to this
proposed plat.
All comments noted in our review memo for this proposed subdivision (dated September 15, 1997)
apply to this revision.

POLICE RELATED COMMENTS
14.06 Police Calls for Service Estimated Annually
CONSTRUCTION PHASE
Theft from construction sites is one of the most common reported crimes in the city. To
protect materials and equipment it is recommended that all materials and tools be locked
up when not in use. The site will need security lighting and any construction trailer should
be fenced in with portable chain-link fencing. The fence will provide both a physical and
psychological barrier to any prospective thief and will demonstrate that this area is private
property.
COMPLETED BUILDINGS
The single-family residences should have solid core doors, preferably metal or metal over
solid wood with peep holes and heavy-duty dead bolt locks. The bolts need to be at least
1-1/2" in length when extended and installed with 3"wood screws.
Sliding windows, including the glass patio doors, will need additional locks; these locks
will need to secure the windows from being pried out of the frames vertically. This means
the locks will need to be placed into the top or bottom of the frames, in addition to any
lock that limits horizontal movement.
Any stairways should be constructed of lattice or metal railing so visibility is possible.
There should not be any solid walls in any stairway that would serve to limit the visibility
up and down the stairs and provide a place for a criminal to hide while waiting for a
homeowner to return home. In addition, any fencing around the homes should be made of
either metal or wood lattice or railing- no solid fencing for the same reason.
The homes should have the addresses listed clearly, with numbers at least 6" in height, of a
color that contrasts with the color of the homes, and placed under a light. This will aid
police or medics who respond to a call in finding the address that they need to go to.
Landscaping around the exterior of the property should not be too dense or high. It is
important to allow visibility. Too much landscaping will give the property the look of a
fortress and make the homeowner feel isolated, and could also possibly give a burglar
sufficient coverage to break into the residences.
Theft from motor vehicle is one of the most common occuring crimes in this city. It is
important that sufficient street lighting be provided leading to each home, as well as for
any outside parking.

Initial Review
I have reviewed the above referenced preliminary plat submittal and have the following comments:
The 50' right-of-way extending into the site is apparently not part of the property under plat and
therefore will require separate approval of the dedication. It may be possible to have council act on it
concurrently if it is specifically noted as a spearate dedication.
Information needed forfinal plat approval includes the following:
Show ties to the City of Renton Survey Control network. See attached.
The geometry will be checked when the ties have been provided.
Provide plat and lot closure calculations.
Note discrepancies between bearings and distances of record and those measured or calculated,if any.
Note the city's land use action number (LUA-97-XXX-FP) and the city's land record number (LND-
10-0329) on the drawing, preferably in the upper right-hand corner. The type size used for the land
record number should be smaller than that used for the land use action number. Please note that the
land use action number for the final plat is different from the preliminary plat number and is unknown
as of this date.
The owner(s) of the property needs to sign the final lot document(include notary blocks as required).
Include a dedication/certification block on the drawing.
Required signature blocks are: (1) City of Renton Administrator of Planning, Building and Public
Works, (2) City of Renton Mayor, (3) City of Renton City Clerk, and (4) City of Renton Director of
Finance, Department of Finance. The appropriate King County approvals are also needed.
The addresses for the proposed lots will be sent under separate cover.
Include the basis of bearing,per WAC 332-130-050 I.b.iii.
Include a statement of equipment and procedures used,per WAC 332-130-100.

lots, then include the following statement on the drawing,juxtaposed to the subject easements: "Area
reserved for private exclusive easement for to be created upon the sale of the lots
shown on this plat." Since the lots created via this plat are under common ownership at the time of
recording, there can be no easement until such time as ownership of one, or more, of the lots is
conveyed to others,together with and/or subject to specific easement rights.
Because this property is located within Zone 2 of Renton's Aquifer Protection Area, the Aquifer
Protection Notice needs to be noted on the drawing. See attached.
An updated Plat Certificate , dated within 45 days of Council action on the approval of the plat, is
needed.
Complete City of Renton Monument Cards,with reference points for new right-of-way monuments.
The surveyor needs to stamp, sign and date the drawings before recording.

1. The minimum fire flow for the single family structures is 1,000 gpm with one fire hydrant
within 300-feet of the structure. Fire flow would be a minimum of 1,500 gpm with two fire
hydrants required if single family structures exceed 3,600 square feet total floor area
including garage and basements.
2. The fire mitigation fees are applicable at the rate of$488 per single family building:
19 single family units x $488.00 = $9,272.00
3. An approved fire sprinkler system is required to be installed throughout all the structures. All
buildings shall have the sprinkler system monitored by an approved alarm company.
4. The fire main serving this sub-division shall be looped to the supply serving the existing
residential building fire hydrants. Fire hydrants shall be provided at 600-foot interval spacing
along the looped fire main.
5. Access roadways appear adequate as proposed.

Dear Mr."Johnson:.
We have received revised drawings and your statement of justification for the conditional use and variance for the above-referenced project.. These items have been routed to staff to continue their
review, but we cannot take your project off of its "on-hold" status until such time that the fee for
the conditional use permit and•variance is submitted. As we discussed, this fee is $1,250.00 and
can be submitted during regular office hours at our third floor customer assistance counter(Mon-
Fri, 8:00 am to 5:00 pm). ..
Based on the amount of time needed to review the materials and prepare staff reports, the project
.will be reviewed by the Environmental Review Committee on either October 14th or October 2-1st.
Following issuance of the environmental threshold determination and completion of the
comment/appeal periods,the public hearing will be held. We anticipate that this date is now ."
November 18th. The previous date of November 4th will not allow adequate time to complete the "
mandated comment/appeal period, and November, 11th is a legal holiday (Veteran's Day) with
government offices closed. - .
I will be away from the'office the week of September 29th,but will be in contact with you upon my
return. If you have any questions regarding this correspondence in the interim,please contact Jana
Huerter at(425)235-2518. — -- " -

Justification for a Conditional. Use Permit
Talbot Ridge
The followingoutlines the necessaryfindings of fact r uired to be met for the Renton
g c9.
Hearing Examiner to grant an approval of a Conditional Use Permit. The request is to
allow the construction of utility lines within a greenbelt area in association with the Talbot
Ridge development pursuant to Renton Code, Section 4-31-35F.2:
Where the provisions of these regulations limit construction of public or private
. utilities or appurtenant structures, approval for such construction may he granted by
approval of a conditional use permit subject to a showing of necessity and
compatibility of the use with these regulations.
1. Comprehensive Plan: The proposed use shall be compatible with the general
purpose, goals, objectives,_and standards of the comprehensive plan, the zoning
ordinance, and any other plan,program,"map, or ordinance of the City of Renton.
This project is within the guidelines outlined by the City of Renton Zoning Code and
the City's Comprehensive plan. The site which the utilities will be associated with is
zoned R-S. This follows all the housing policies and goals with housing for the City
within the designated zone.
Policy H-14- Minimum density requirements shall be established in all zones
which allow residential development to ensure adequate capacity for growth and
create greater efficiency in the provision of urban services.
Policy H-85 - Provide homeownership opportunities in all neighborhoods.
In addition,this project will provide for infill development, a condition of the
comprehensive plan:
Policy H-4- Encourage infill development as a means to increase capacity.
In order for this development to take place,utilities must be available at the site. The
only feasible connection of utilities is to tie into the existing systems(sewer and
stormwater)within the Springbrook Condominiums located to the west of the subject
site. For thus connection to take place, it must be made through the greenbelt area.
In addition,this development will preserve as much greenbelt space as possible, and
will create better stability on the slope by providing an up to date drainage plan which
will help control any existing erosion and sedimentation for the surrounding area.

2. Community Need: There shall be a community need for the proposed use at the
proposed location. In the determination of community need, the Hearing Examiner
shall consider the following factors among all other relevant information:
1). The proposed location shall not result in either the detrimental
overconcentration of a particular use within the City or within the immediate area
of the proposed use.
2). That the proposed location is suited for the proposed use.
With the smaller lots being created as a result of the development, a differing housing
type and value will be available at this site. However,in order for this development to
take place,utilities must be available to the developer. The only feasible option is to
provide a utility line directly from the proposed Talbot Ridge to the existing
Springbrook development located down the hill and to the west. The Springbrook
development anticipated this utility connection and provided the appropriate sewer
sizing and stub to serve the proposed project.
3. Effect on Adjacent Properties: The proposed rise at the proposed location shall not
result in substantial or undue adverse effects on adjacent property.
Clearing the greenbelt for utilities is the only feasible alternative for this site. It will
not result in any undue or adverse impacts to the surrounding area. Hill holders,or
other slope stabilizing mechanisms,will be placed appropriately throughout the slope
to insure stability. All clearing activities will be during approved hours of operation
and will strictly follow city codes and ordinances.
•
II
Justification for a Variance Request
Talbot Ridge
The following outlines necessary findings of fact required to be met for the Renton
Hearing Examiner to grant a Variance Request to allow the construction of utility lines in
an area where the predominant slope is greater than 40% pursuant to Renton City Code
Section 4-9-5D:
No tree cutting or land clearing is permitted within twenty five feet of any shoreline
area, within twenty five feet of the ordinary high water mark of creeks, in a wetland
area, or on parcels where the predominant slope or individual slope is in excess of
forty percent except enhancement activities.
,4_ That the applicant suffers undue hardship and the variance is necessary because
of special circumstances applicable to subject property, including size, shape,
topography, and location or surroundings of the subject property; and the strict
application of the Building&Zoning Code is found to deprive subject property owner of
rights and privileges enjoyed by other property owners in the.vicinity and under identical
classification.
The clearing which will take place is a direct result of the utilities which will Lie in to the
existing Springbrook development down the slope and to the west. This is the only
feasible way in which to provide the site with the necessary utilities. This property is
adjacent to the King County boundary line and the City of Renton is the only utility
purveyor serving this site with sewer. No other gravity fed sewer system option exists for
this site which is both zoned for and designated in the comprehensive plan for up to 8
units per acre. All clearing for the proposed utility lines will strictly apply to all Renton
codes, ordinances and laws.
B. That the granting of the variance will not be materially detrimental to the public
welfare or injurious to the property or improvements in the vicinity and zone in which
subject property is situated.
The developer would install hill holders or other slope stabilizing mechanisms to help
stabilize the slope. This will help insure the utility connection will not be detrimental to
the hillside and will help minimize the affect this development will have on the slope and
greenbelt areas. All clearing will be in accordance with the City of Renton's codes and
ordinances.
C. That approval shall not constitute a grant of special privilege inconsistent with
the limitation upon uses of other properties in the vicinity and zone in which the subject
property is situated
The property sits on a bluff overlooking the green river valley. East of the subject site is
King County jurisdiction and south is a limited triangular portion of the city designated R-
8 by the city zoning code. Because this property sits at a higher elevation adjacent to the
easterly boundary to the city,the only potential for Renton sewer service is downhill to the
west. Without this sewer connection,the development could not meet the growth
management minimum density of the site when assuming IA acre lots for on-site septic.
There is only a limited number of properties within this small triangle of R-8 zoning where
similar conditions apply and would require similar variances for utilities extending westerly
through the greenbelt and steep sloped areas_
D_ That the approval, as determined by the Hearing Examiner or Board of
Adjustment, is a minimum variance that will accomplish the desired purpose.
If approved,the only action that will take place within the steep slope will be to build an
above ground storm pipe and a underground sewer line tying in with the existing
Springbrook utility lines. No other activity is proposed within this area.

Dear Leslie:
Thankyou foryourquick response to our submittal of Talbot Ridge. Regarding your June 27th
pg g
,A c_ letter, enclosed is a map of Talbot Ridge with the existing and proposed zoning boundary lines.
is, To help you understand the proposed zoning boundary line better, I will explain to you the
t ` y J•5 methodology in reaching this decision:
1""� ) 1. We calculated the top of slope line within the proposed Talbot Ridge and Summit Park
itor developments(see attached sheets).
L.P 2. On the Kroll map (see attached), I drew the current zoning line using the City of Renton's
r, " ' Zoning Map. Plus, I connected the top of slope lines for Talbot Ridge and Summit Park.
X 3. After defining the new zoning line for the R8/R1 zone, using top of slope, I then attached the
top of slope line to the Talbot Ridge site.
4. Using this methodology, this should be the new zoning line(approx.)
Under the current zoning boundary, Talbot Ridge has 2.12 acres in the R8 zone, and 2.43 acres in
the Rl zone. Under the new zoning boundary, the R8 zone increases to 2.88 acres, and the R1
zone decreases to 1.67 acres.
I hope this answers any questions you may have. Should you have any more questions or require
any additional information, please don't hesitate to call me, 821-8448. Also, please note that the
copies of the wetland report and delineation are forthcoming.

MEMORANDUM
DATE: February 5, 1997
TO: Pre-Application File
FROM: Mark R. Pywell, AICP
SUBJECT: Springbrook East Preliminary Plat
Pre-App 97-08
We have completed a preliminary review of the pre-application for the proposed development. The
following comments on development and permitting issues are based on the pre-application submittals
made to the City of Renton by the applicant. The applicant is cautioned that information contained in this
summary may be subject to modification and/or concurrence by official decision makers (e.g., Hearing
Examiner, Zoning Administrator, Board of Adjustment, Board of Public Works, and City Council).
Review comments may also need to be revised based on site planning and other design changes
required by City staff or made by the applicant. The applicant is encouraged to review all applicable
sections of the Renton Municipal Code.
1. The project site is located to the east of Talbot Road S. and is south of SE Carr Road. The project
site appears to have a split zoning R-1 and R-8, copies of these zones are attached for your review.
2. The applicant is proposing a subdivision for 14 lots. These lots would be used for the construction of
single-family homes.
3. The applicant will need to prepare a plan that demonstrates the area of steep slope and the area that
is zoned R-8 and the area that is zoned R-1. The acreage of these areas should be shown on the
plan. This plan should be submitted with the subdivision application. A copy of the subdivision
application is attached for your use. All items listed on the application must be submitted with the
application and any other information requested herein must also be submitted at the same time.
4. Seeps and wetlands have been identified in the area of this site. The applicant will need to have a
biologist walk the to identify the fauna and flora on-site. Any wetlands identified by the biologist will
need to be delineated and a report will be required with the application. If no wetlands are identified
a letter should be submitted indicated that no wetlands were identified on this site.
5. A slope map for the steep slope and the portion of the site to be developed will need to be submitted
with the application.
6. A geologic report discussing soil types, slope stability and any required setbacks from the steep
slope area will need to be submitted with the application. Coal mines have been identified to the
north of this site. The geologist should review the appropriate records to ensure that the site does
not have any identified coal mine shafts that will need to be addressed.
7. The plans should demonstrate any required cut and fills, the quantity of material required, and if any
material will need to be removed on imported.

Project Narrative
for the Preliminary Plat of
Talbot Pam. p.i 06 p
The preliminary plat of Talbot Ridge is a 19-lot single-family detached project on 4.55
acres of land. The tax parcel number of the forested and undeveloped land is 312305-
9063-06. The site is located just east of Talbot Road, however, the only access to the site
will be via an off-site extension of 102'd Avenue SE. The roadway extension will end in a
cul-de-sac within the proposed development and no access will be provided through the
site to Talbot Road. The proposed lots will primarily be served by the proposed South
47th Ct. However, lots 1-6 will be served by a private 20-foot wide access easement.
The site maintains two zoning districts. The easterly portion of the property, where
development is anticipated to take place, is zoned R-8. The westerly portion on the site is
zoned R-1 primarily as a result of the steep slopes. The City of Renton has confirmed that
the zoning boundary between the R-1 and R-8 districts is the top of slope and the plan has
been designed to represent this boundary line. The zoning densities are consistent with the
comprehensive plan.
The westerly portion of the site contains steep slopes which are in excess of 40 percent.
No development, other than necessary utilities, are proposed within the steep sloped areas.
For the most part, the trees and understory on the steep slopes will be preserved. A
preliminary geotechnical report has been prepared and submitted with this application. An
off-site wetland exists to the east of the site which will be impacted by the development of
the access roadway. Based on the proposed grading plan and surveyed wetland location,
approximately 3,800 square feet of the wetland would be impacted by the development of
the roadway. The wetland disturbance is partially within King County jurisdiction and
partly in the City of Renton. A wetland report is being prepared and will be submitted as
an addendum to this application. Hydrology of the wetland feature is conceptually being
Y gY P Y
maintained by a proposed 24"culvert under the proposed access roadway. This storm
water conveyance system ultimately flows to the Green river and out to the Puget Sound.
The existing King County access road(102nd Avenue SE)maintains curb, gutter and
sidewalk on the easterly side of the street in the vicinity of the proposed project. The
westerly side of the roadway is a thickened edge section. This development anticipates
extending 102nd Avenue SE to the north and tying into an access roadway(47rh Court) at
the City of Renton boundary limits. 47th Court will be developed as a full street with a
sidewalk, curb and gutter on the north side. The plat will provide rolled curbs and a
sidewalk extending along both sides of the street and around the cul-de-sac bulb.
A final grading plan has not been developed to date, however, it is anticipat® -fhat�mo�,,ct f
the vegetation on the portion of the site to be developed will be removed. ' he vegetat`id n
az
in the steep sloped areas will be retained, except where conflicts with necessary utility
lines exist. It is anticipated that an export of material will be required for this
development. The quantity will not be substantial, given the size of the project.
Construction of the project will occur as soon as all necessary approvals and permits have
been issued by the City of Renton. Estimated start of construction is July 1998.
•
Preliminary Plat of Talbot Ridge
Construction Mitigation Plan
(June 24, 1997)
A) What are the proposed construction dates (beginning and ending dates) and phasing, if
P P (bg g
any:
Construction is anticipated to begin in the summer of 1998 with the plat being recorded by
spring of 1999. At this time no phasing is anticipated with the project development.
B) What are the anticipated hours of construction related operations:
The hours of construction related activities would be limited to those customary for the
City of Renton. It is estimated that construction related activities would generally be from
7:00 A.M. to 9:00 P.M. Monday through Friday and, if necessary, 9:00 A.M. to 5:00 P.M.
on Saturday and Sunday.
C) What are the proposed hauling/transportation routes:
It is not known at this time if exportation of soils will be required as a result of the
proposed development. However,if hauling is necessary,the site is near Talbot Road
which is a main north/south arterial. South 55th Street and 102nd Avenue SE may be used
to provide access from Talbot Road to Highway 167.
D) Measures to be implemented to minimize dust, traffic, and transportation impacts, mud,
noise, and other noxious characteristics:
Frequent watering of the site during construction would limit the quantity of dust
particulates created by workers' vehicles and heavy machinery. Because the site is
adjacent to a main north/south arterial, no substantial impacts on traffic and transportation
are anticipated other than road improvement related construction.
Soils being transported off the site and onto 102nd Avenue SE could be minimized by
placing crushed rock at the entrance to the development site during construction.
Frequent watering of the entry location and street sweeping would further help control
transient soils. Noise and other generally noxious characteristics associated with land
development will be temporary and generally would not beginning prior to sunrise and
would generally not continue beyond sunset. Because the area is primarily surrounded by
single-family low density residential housing,the impacts to the existing neighborhood
would be minimal. SC

IMPACTS TO THE EARTH, IF ANY:
During construction,temporary erosion/sedimentation control devises would be
implemented to minimize erosion. Key elements of a typical erosion control
measure would consist of clear marking of clearing limits, installation of ditches,
sedimentation traps, filter fabric fencing and biofiltration areas prior to the start of
construction. A plan including part or all of the above items will be submitted for
review and approval to the City of Renton prior to any grading activity on the subject
site. In addition,the project will comply with NPDES requirements and will be
covered under the State Waste Discharge General Permit.

and roofs would be collected in a series of catch basins and routed to a detention
system constructed specifically for this development site. The storm water would be
released as a control rate not to exceed that of the post development rate for the 2,
10, and 100 year/24-hour storm events. The detention outfall will be tightlined along
the southerly property line, and will tie into the storm system of Talbot Park located
west of the subject site. In addition to this,there will be a separate detention system
for the construction of the off-site access roadway. This detention system will
discharge water flows into the wetland feature.
2) COULD WASTE MATERIALS ENTER GROUND OR SURFACE WATERS? IF SO,
GENERALLY DESCRIBE.
Some pollutants normally associated with residential development could enter the
surface water, however,the amount would be minimal since the on-site drainage will
include the use of treatment facilities in conformance with current city standards.
The proposed plans for stormwater and run-off control are expected to minimize
waste materials or pollutants entering ground water resources and/or surface waters.
D. PROPOSED MEASURES TO REDUCE OR CONTROL SURFACE, GROUND,AND

INTRODUCTION
The proposed project is to construct 19 single family dwelling units on approximately 4.55
acres located between Talbot Road and 102nd AVE SE in the City of Renton. In order to
provide site access, frontage improvements will be done from the existing pavement of
102nd AVE SE to the site(approximately 935 linear feet of proposed road).
The 4.55 acre site is covered predominantly with a combination of scattered trees and
brush. The site slopes from east to west at approximately 5 to 40 percent. Runoff will be
collected by a tightline conveyance system and routed to an underground detention
facility. Runoff will leave the detention facility and connect to the existing tightline
conveyance system for the Springbrook development located west of the property. Runoff
from approximately 0.44 Ac of the frontage improvements will be conveyed to the onsite
detention facility. The remaining runoff from the frontage improvements will be conveyed
to a detention pipe which will discharge into an existing swale. According to the "Soil
Survey-King County Area", the site is underlain with Alderwood, type 'C' soils.

DRAINAGE CONCEPT
The storm drainage systems for the proposed project were designed with reference to
standards found within the 1990 King County Surface Water Design Manual
(KCSWDM). The onsite drainage system will convey runoff from the developed site and
a portion of the frontage improvements within a tightline drainage system to an
underground detention vault located near the west property line. The detained storm
drainage will connect to an existing tightline conveyance system located in the
Springbrook project just west of the site.
The drainage system for the frontage improvements will convey runoff to a detention pipe
located in SE 183`d PL. The detained storm water will then be discharged into an existing
swale.
Both detention facilities were designed to provide peak rate runoff control for the 2, 10,
and 100-year, 24-hour storm events. The facilities were designed such that the post-
developed peak runoff rates are attenuated to the pre-developed peak runoff rates for each
of the 2, 10, and 100-year, 24-hour storm events. A 30-percent volume correction factor
(factor of safety) will also be applied to the live storage volume for each facility. Water
quality enhancement will be provided within the facilities through the use of "dead
storage". The amount of"dead" storage provided is equal to the volume of the "water
quality" (6-month) storm event. The precipitation to be used for the water quality storm
event will be 64% of the 2-year, 24-hour precipitation.
PRELIMINARY STORM DRAINAGE REPORT FOR TALBOT RIDGE-PAGE-3
DOWNSTREAM ANALYSIS
Runoff leaving the site will connect with the Springbrook project's conveyance system
located west of the site. A downstream analysis was performed by Triad Associates for
the Springbrook project. Please reference excerpts from the Springbrook Technical
Information Report located in the appendix of this report. In general, the downstream
conveyance system is considered in"good" condition and shows "no evidence of drainage
related problems".
, Runoff leaving the detention pipe located in SE 183rd PL will drain into an existing swale.
The swale, labeled as tributary #0010 by The King County Basin Reconnaissance
Program, flows into tributary #0060 approximately'0.4 miles downstream of the site.
Please reference the Basin Exhibits located in the appendix of this report. Ultimately the
tributaries flow into the Black River stream bed and are conveyed to the Green River.
PRELIMINARY STORM DRAINAGE REPORT FOR TALBOT RIDGE-PAGE-4
DETENTION CALCULATIONS
The following detention calculations were performed using Engenious Systems, Inc.'s
hydrology program Water Works. The hydrographs were developed using the S.B.U.H.
methodology with a King County Type I-A, 24-hour (User 1) rainfall distribution.
Separate S.C.S. curve numbers were applied for the impervious and pervious portions of
the site. Approximately 0.44 acres of the frontage improvements will be conveyed by the
onsite system to the detention facility located near the west property line. A separate
conveyance system will direct runoff from the remainder of the frontage improvements to
a detention pipe located along SE 183`d PL. The detention pipe will discharge into an
existing swale.
The developed hydrographs for each detention system were routed through a
"theoretical" structure to determine the theoretical volume of storage required. The
theoretical volume of live storage was then increased by the 30-percent volume correction
factor (factor of safety) to determine the actual volume of live storage required. Please
refer to the Existing and Developed Condition Maps and the table of Curve Numbers
located in the Appendix of this report. The total precipitation for the water quality, 2, 10,
and 100-year, 24-hour storm events are 1.28", 2.00", 2.90", and 3.90", respectively.
Elevations used for the detention facilities are assumed. Exact elevations will be used in
the final engineering design and accompanying report. _ o

Live Storage
The theoretical volume of live storage required is 10,376 cubic-feet: In addition to the
30% volume correction factor required by the Department of Ecology and additional 3%
volume correction factor was applied to the live storage volume to account for
inaccuracies during vault construction. Therefore, the actual volume of live storage
required is 13,800 cubic feet (1.33 x 10,376 ft). The actual detention vault was
designed to provide 14,000 cubic feet of live storage(20'x 100'x 7').

Dead Storage
The facility will be designed to provide "dead" storage in the amount equal to the volume
of the water quality storm event. The volume of the water quality hydrograph(64% of the
2 year precipitation)' was determined to be 0.21 Ac-ft or 9,150 cubic-feet as stated
previously in the Developed Condition Hydrograph Summary. A 3 % factor of safety was
then applied to account for inaccuracies that may occur during vault construction. The
required volume of dead storage is therefore 9,925 cubic feet (1.03 x 9,150). The
actual detention vault was designed to provide 10,000 cubic feet of dead storage (20'x
100'x 5'). The detention vault will have a total depth of 12 feet

Section III: OFF-SITE ANALYSIS
A downstream drainage analysis was performed on December 7, 1995, a cloudy and cold
day. Please refer to the Downstream Drainage Map, located in the Appendix, along with
the following description of the downstream system. There was a small quantity of runoff
being conveyed within the existing drainage ditches and tightline storm drainage systems.
Runoff from the site currently sheet flows in a westerly direction and is collected within
the existing drainage ditch located on the east side of Talbot Road South. The drainage
ditch is approximately two to three feet deep and has side slopes of 2:1, with a one foot
base width. The ditch runs northerly along Talbot, Road South, at a slope of
approximately one-half to one percent, while conveying flows through a series of(3) 12-
inch diameter culverts. Immediately north of the subject property, flows are conveyed
beneath an existing driveway via a 12-inch diameter HDPE culvert. Runoff then continues
northerly within the ditch for approximately 200 feet. Then, runoff is collected within a
City of Renton storm drainage system via a 12-inch diameter CMP culvert (located across
from South 45th Place). Runoff is conveyed within this tightlined conveyance system to a
point beyond one quarter-mile downstream.
The downstream conveyance system was in good shape and showed no evidence of
drainage related problems (flooding, erosion, etc.). The system appears to have more than
adequate capacity to handle the existing flows. The King County Sensitive Areas Folio
was researched and the site was not found, nor was it tributary to (within at least a quarter
mile), any sensitive areas (wetlands, erosion hazard areas, etc). As such, it is our opinion
that a detention standard more restrictive than matching the pre-existing flows for the 2,
10, and 100-year, 24-hour storm events is not warranted.

102ND AVENUE SE
RENTON, WASHINGTON
June 20, 1997
Project No. G97177A
I. PROJECT AND SITE CONDITIONS
1.0 INTRODUCTION
This report presents the results of our subsurface exploration and preliminary geotechnical
engineering feasibility study for the proposed storm water detention vault located one-fifth of a
mile west of the end of 102' Avenue SE (Figure 1). The approximate proposed vault location
and approximate locations of the explorations accomplished for this study are presented on the
Site and Exploration Plan, Figure 2. After site access is available for construction equipment,
additional exploration pits are recommended to further evaluate subsurface conditions in the
vault area. In the event that any changes in the nature, design or location of the-structure are
planned; or if subsurface conditions are found to differ significantly from those encountered in
the explorations for this study, the conclusions and'recommendations contained in this report
should be reviewed and modified, or verified, as necessary.
1.1 Purpose and Scope
The purpose of this study was to provide subsurface data and preliminary geotechnical
recommendations to be utilized in the design and development of the subject project. Our
study included a review of available geologic literature, 3 hand borings, and performing
geologic studies to assess the type, thickness, distribution and physical properties of the
subsurface sediments and shallow ground water conditions. Preliminary geotechnical
engineering studies were also completed to determine the type of suitable foundation, allowable
foundation soil bearing pressures, anticipated foundation settlements and drainage
considerations. This report summarizes our current field work and offers development
recommendations based on our present understanding of the project and surrounding geologic
conditions.
1.2 Authorization -
Verbal authorization to proceed with this study was granted by Mr. Ron Guest of Triad and
Associates on behalf of the owner, White Star Development. Our work was completed in
accordance with our proposal dated June 10, 1997. This report has been prepared for the
exclusive use of White Star Development and their agents, for specific application to this
project. Within the limitations of scope, schedule and budget, our services have been
performed in accordance with generally accepted geotechnical engineering and engineering
geology practices in effect in this area at the time our report was prepared. No other warranty,
expressed or implied is made. Our observations, findings, and opinions are a means to
identify and reduce the inherent risks to the owner.
2.0 PROJECT AND SITE DESCRIPTION
This report was completed with and understanding of the project based on a May 28, 1997
grading and drainage plan completed by Triad and Associates that showed the site with
elevation contours, existing structures, and,the planned locations of lots, paved roadways, and
the detention vault. We understand that the development will include fourteen (14) lots for
single family residences. Access is planned from the east off 102' Avenue SE.
Present plans call for the construction of a 20 foot by 100 foot by 6 foot deep storm water
detention vault located east of the proposed housing development. The north to south trending
rectangular vault will be situated on a gently sloping ridge, also trending north to south, with
well defined steep slopes on both the western and northern portion of the site. The steep,
western slope is located about 100 feet west of the proposed detention vault, and extends down
to a developing condominium site. Based on the previously referenced grading and drainage
plan, the detention vault will be located in an area with an elevation change of about 40 feet
from the end of 102nd Avenue SE. With the exception of a narrow mid-slope terrace, this slope
has an approximate inclination of 2H:1 V (Horizontal:Vertical). Located approximately 200
feet northeast of the proposed vault, the steep, northern slope extends down to a road on the
valley floor, with an approximate slope of 2H:1V.
The site was generally vegetated with fir and cedar trees, and a moderate to thick covering of
brush, ferns, and blackberries. Other land use in the vicinity consisted of residences and
undeveloped land.
Our geologic reconnaissance did not reveal evidence of debris flow or landslide activity in the
vicinity of the proposed vault or surrounding slopes. No evidence of adverse ground
water/springs or surface water conditions were observed on the slopes either.
3.0 SUBSURFACE EXPLORATION
Our field study included advancing a series of 3 hand borings to gain information about the
subsurface soil and shallow ground water conditions at the site. The various types of
sediments, as well as the depths where characteristics of the sediments changed are indicated
on the exploration logs presented in the Appendix. The depths indicated on the logs where
2
conditions'changed may represent gradational variations between sediment types in the field.
Our borings were approximately located in the field by measuring from known site features
shown on the topographic map.
The conclusions and recommendations presented in this report are based on our geologic
reconnaissance and the hand borings completed for this study. Because of the nature of
exploratory work below ground and limited depth capability of hand exploration methods,
extrapolation of subsurface conditions is necessary, and it should be noted that differing
subsurface conditions may sometimes be present due to the random nature of deposition and
the alteration of topography by past grading, or filling. The nature and extent of any variations
in soil conditions may not become fully evident until equipment access is secured for
exploration pits or until construction. If variations are observed at that time, it may be
necessary to re-evaluate specific recommendations in this report and make appropriate changes`.
3.1 Hand Borings
The borings were completed on June 16, 1997 using a hand auger. Materials encountered
from the borings were studied and classified by a geologist from our firm. All borings were
backfilled after examination and logging. Selected samples were then transported to our
laboratory for further visual classification as necessary.
4.0 SUBSURFACE CONDITIONS
Subsurface conditions on the parcel were inferred from the field explorations accomplished for
this study, visual reconnaissance of the site and review of published geologic literature. As
shown on the field logs, the upper portion of the borings generally encountered about 1 to 2
feet of loose, moist, dark brown to brown silty sand (topsoil) with varying amounts of roots
and other organic materials.
Beneath the topsoil were sediments that were interpreted as undifferentiated glacial deposits.
•
These undifferentiated glacial deposits consisted of loose grading to medium dense, damp to
moist, brown silty sands and soft grading to medium stiff, moist to wet, mottled gray and red
sandy silts. Some organics, scattered cobbles and gravel lenses were also encountered. A lens
of loose, brown, well-rounded, cobbly sand was encountered at a depth of approximately 4 feet
in HB-2 and HB-3, but was impenetrable in HB-2 after 4 separate borings were attempted.
However, the continuation of HB-3 at 4 feet was successful, and medium dense, moist, brown,
silty fine sand was encountered below the upper sand and silt. All of the undifferentiated
deposits are most likely the result of glaciofluvial sediment deposition.
4.1 Hydrology
Ground water seepage was not encountered in the borings at the time of our field study.
• 3
A small drainage swale was present adjacent to 102nd Avenue SE, and sloped down to the
northwest. Based on a USGS topographic map, this is a seasonal drainage that is only affected
by heavy precipitation.

II. PRELIMINARY.DESIGN RECOMMENDATIONS
5.0 INTRODUCTION
Our explorations, geologic reconnaissance and interpretations of published geologic literature
indicate that from a geotechnical standpoint, the site is suitable for construction of the proposed
detention vault. The bearing strata (medium dense sand) was relatively shallow in 5 our
exploration borings and should be encountered at the proposed 6 foot excavation depth for the
vault foundation. No evidence of past landslide or debris flow activity were observed in the
vicinity of the vault, nor were they mapped on geologic literature. It is therefore our opinion
that the vault may be constructed using a conventional, shallow foundation and retaining walls,
without a significant adverse impact on slope stability. The construction area should be
restored by grading to match the surrounding, natural contours and revegetating with a suitable
seed/plant mixture.
6.0 SITE PREPARATION
Site preparation for planned vault should consist of stripping and removing the upper, organic
topsoil horizon. This material may be set aside for later reuse as a mulch layer to promote
germination and growth of natural plants. Once the vault-footprint is stripped, the excavation
for the vault chamber may proceed. It is anticipated that the depth of the excavation will be on
the order of 6 feet, and based on our exploration borings, we anticipate loose, grading to
medium dense silt, sand and gravel sediment will be encountered. We do not expect that
significant ground water seepage will be encountered in the planned excavation, however,
seepage zones may occur during the wetter periods of the year.
, In our opinion, stable construction slopes should be the responsibility of the contractor and
should be determined during construction based on the encountered soil and ground water
conditions. For estimating purposes, we anticipate that temporary, unsupported cut slopes in
the silt, sand and gravel sediments may be-made at a maximum slope of 1.5H:1V. As is
typical with earthwork operations, some sloughing and raveling may occur and cut slopes may
have to be adjusted in the field. In addition, WISHA/OSHA recommendations should be
followed at all times.
Some of the on-site sediments contained a high percentage of fine-grained material which
makes them moisture sensitive and subject to disturbance when wet. The contractor must use
care during site preparation and excavation operations so that the underlying soils are not
5
.
softened. If disturbance occurs, softened soils should be removed and the area brought to
grade with structural fill compacted to a minimum of 95 percent of ASTM:D 1557.
Once the excavation is completed to the required depths and any softened soils removed to
replace by structural fill,. the subgrade should be recompacted to at least 95 percent of the
above standard prior to foundation construction. After the subgrade is prepared and approved
by the geotechnical engineer, foundation construction can begin.
7.0 FOUNDATIONS
Conventional spread footings may be used for support of the vault when founded on the
medium dense natural sands or structural fill placed as previously discussed. We recommend
that an allowable soil bearing pressure of 2,500 pounds;per square foot (psf) be utilized for
design purposes, including 'dead and live loads. Footings should be buried at least 18 inches
below surrounding grades for frost protection. All footings must penetrate to the prescribed
bearing strata and no footings should be founded in or above loose/soft or organic soils. All
footings should have a minimum width of 16 inches.
The area bounded by lines extending downward at a 1H:1V inclination from,any footing must
not intersect another footing or intersect a filled area which is not being compacted to at least
95 percent of ASTM:D 1557.
Anticipated settlement of footings founded on medium dense sand or approved structural fill
should be less than 1 inch. However, disturbed soil not removed from footing excavations
prior to footing placement, could result in increased settlements. All footing areas should be
inspected by Associated Earth Sciences, Inc. (AESI) prior to placing concrete to verify that the
design bearing capacity of the soils has been attained and that the construction conforms to the
recommendations_,contained in this report. Such inspections may also be required by the
governing municipality.
8.0 LATERAL WALL PRESSURES
Horizontally backfilled walls which are free to yield laterally at least 0.1 percent of their height
may be design using an equivalent fluid equal to 35 pounds per cubic foot (pcf). Fully
restrained, horizontally backfilled rigid walls which cannot yield should be designed for an
equivalent fluid of 50 pcf. The upper, east wall will likely have a sloping backfill condition at
an approximate inclination of 5H:1V and should be designed for an equivalent fluid of 40 pcf
for yielding conditions and 60 pcf for restrained conditions. The lateral pressures presented
above are based on the conditions of a uniform backfill consisting of a select on-site sand and
gravel backfill compacted to 90 percent of the ASTM:D 1557. A higher degree of compaction
is not recommended as this will increase the pressure acting on the walls.
Proper drainage must be provided so that hydrostatic pressures do not develop against the
walls. This would involve installation of a minimum 1 foot wide blanket drain for the full
height of the wall using imported, washed gravel. A perforated, rigid, PVC pipe should be
placed at the wall base elevation and sloped to drain to a suitable outlet location. The drain
`pipe must be hydraulically connected to the free-draining wall backfill material.
•
9.0 SLOPE REMEDIATION
Once the vault is constructed, the areas disturbed by the construction should be restored and
planted to reduce the potential for erosion and slope instability. In general, we recommend
that the following measures be used.
•
1. All excavations should be backfilled with granular, natural soils derived from
on-site, and compacted to at least 90 percent of ASTM:D 1557.
2. Finished grades should be contoured to blend into the surrounding natural
slopes, and to avoid concentrated flows of runoff water. Concentrated runoff
must not be directed onto or above more steeply sloping areas of the site.
3. Disturbed areas should be revegetated with a suitable hydroseed mixture. To
promote plant germination and growth, mulching the slopes with the on-site
topsoil sediments is recommended prior to hydroseeding. The mulch/topsoil
thickness should not exceed 1 foot.
10.0 CLOSURE
• At time of this report, site grading, structural plans, and construction methods had not been
finalized. The recommendations presented in this report are therefore preliminary and should
• be reviewed and/or modified as necessary as new design information becomes available. We
are available to provide additional geotechnical engineering exploration or consultations as the
project design develops and possibly changes from that upon which this report is based.
We are also available to provide geotechnical engineering and monitoring services during
construction. The integrity of the foundation depends on proper site preparation and
construction procedures. In addition, engineering decisions may have to be made in the field
in the event that variations.in subsurface conditions become apparent.
•
•
We have enjoyed working with you on this study and are confident that our recommendations
will aid in the successful completion of your project. If you have any questions or require
additional information, please do not hesitate to call.

Re: Wetland Investigation: Right-of-Way for Talbot Ridge Subdivision -
_ City of Renton.
Dear Mr. Lund:
Per your request, a site-specific wetland investigation was conducted on June 1, 1997. The
subject site is a new right-of-way proposed for access into the Talbot Ridge preliminary
subdivision. The site is located at the end of 102nd Avenue S.E. just north of the Windsor
Heights residential development at S.E. 185th Place, King County, Washington (Section 31,
Township 23 North, Range 5 East, Willamette). Most of the right-of-way site consists of mature,
deciduous forest. The proposed right-of-way area was not field-located at the time of this
investigation.
Site/Project Description
The subject site is a proposed 50-foot wide right-of-way about 700 feet long just inside the
current south boundary of the City of Renton. The new street right-of-way, S. 47th Court, will
run along the north boundary of King County, in the City of Renton, to extend access from 102nd
Avenue S.E. The Talbot Ridge Subdivision project is an approximately 5-acre parcel located to
the west. This parcel appears to be"landlocked"as there is no designated access easement.
The Talbot Ridge subdivision proposal consists of 19 new residential lots. The State of
Washington currently owns the land area proposed for S. 47th Court right-of-way access. The
area is predominantly forest with significant deciduous tree cover. Site topography is described
as being gently sloping except for a swale area on the eastern portion. The identified swale area
conveys surface water runoff from mostly residential development located to the southeast along
102nd Avenue S.E. In order to provide access to the proposed Talbot Ridge project, the new
road will need to cross over the subject swale area.
Purpose/Method
The primary purpose of the investigation was to determine if wetland habitat is present and
provide assistance with County and City environmental permits. The City of Renton and King
County require the U.S. Army Corps of Engineers 1987 Wetlands Delineation Manual
(Environmental Laboratory 1987)be used for wetland determination. In accordance with a recent
change, the new Washington State Wetlands Identification and Delineation Manual must be used
by all jurisdictions(WADOE-3/31/97,Letter). The attached letter from Dept. of Ecology explains
the new manual's consistency with 1987 Corps Manual methodology.

Mr. Colin Lund

Public natural resource documents were reviewed for the site. King County's Sensitive Areas
Map Folio (1990) has not mapped wetlands as being on the site; however has mapped the
subject drainage as an "unclassified stream". Renton has not formally adopted wetland or,stream
inventories; however, reported that this portion of the City has not been mapped yet.
According to the King County Area Soil Survey (US Soil Conservation Service 1973), the
property is mapped as Alderwood gravelly sandy loam soil,.6 to 15 percent slopes (AgC). The
Alderwood mapped soil unit is associated with upland habitats. Smaller areas of poorly drained
soils included within this map unit are reported as Norma, Bellingham, Seattle, Tukwila, and
Shalcar series. If present, these soil inclusions may be associated with wetland habitats.
Three 0.01-acre data plots were established within the swale area associated with the proposed
right-of-way improvement. In addition to vegetative composition/cover data, soil samples were
taken at all data plots. . Wetlands were delineated where vegetation, soils, and hydrology all
reflect hydric conditions. Data plot field forms are attached to this report.
Investigation Findings
The following subsections include soil, hydrology, and plant community descriptions observed on
the subject property during the 6/1/97 right-of-way investigation. An unclassified stream flows
south to north through the subject site. A small wetland was identified associated with the stream.
The delineated wetland exists within the stream corridor generally south of-Flags#2 and #12 (see
attached map). As the slope gradient steepens the drainage channel narrows and is contained
by steeper banks. The attached professional survey/site map was provided by Triad
Associates, Inc. The total size of the delineated wetland area is approximately 1,800 square feet.
Soil/Hydrology
Generally, the investigated wetland soils have "A" horizon chroma values of 10YR 3/1 and 3/2,
with mottles, extending to a depth of 18 inches. Adjacent upland soils have chroma values of
10YR 3/2 without mottles to about the same depth. The observed soils were sandy to very
sandy barns that may be considered as variations within the Alderwood soil series.
A significant contribution of seasonal runoff appears to originate from old and recent residential
development to the south. Stormwater water runoff from the Windsor Heights residential
development is conveyed under 102nd Avenue S.E. through a culvert directly into the stream
channel.
Generally, the site's intermittent, surface flows are confined to a channel less than 6 feet wide.
Subsurface hydrology was observed in the wetland area during the 6/1/97 investigation.
However, this drainage area is located in the upper portion of the stream corridor and it is
probably dry during the summer months.
Mr.Colin Lund
July 30, 1997

Wetland/Stream Community
Due to unrelated, previous clearing, the subject wetland is an emergent area dominated by reed
canarygrass. Additional species observed include common velvet grass (Holcus lanatus),
speedwell (Veronica sp.), and giant horsetail (Equisetum telmateia). Using the US Fish and
Wildlife Service classification system (USFWS .1979), this wetland is classified as palustrine,
emergent with seasonal hydrology.
Most of the riparian wetland area exists within King County's jurdisdiction. Therefore, using the
Sensitive Areas Ordinance (King County 1990) it would be rated a Class 3 because of it's small
size and limited habitat.
The stream corridor has tree cover dominated by black cottonwood (Populus baslamifera). Big-
leaf maple (Acermacrophyllum) and red alder (Alnus rubra) are also growing adjacent to the
stream. Observed shrub species include salmonberry (Rubus spectabilis), Himalayan
blackberry (Rubus discolor), Indian plum (Oemlaria cerasiformis), and thimbleberry (Rubus
parvifiorus). Groundcover within the stream channel includes mannagrass (Glyceria sp.) and
great hedgenettle(Stachys ciliata).
• As reported, the City of Renton has not inventoried this stream. King County has mapped the
drainage as an "unclassified stream" and it could be rated Class 3 because it is seasonal and
does not support salmonid fish species. The subject stream is mapped as a tributary to Panther
Creek which is located a significant distance to the north.
Wetland/Stream Development Considerations
The proposed right-of-way development for the Talbot Ridge project is somewhat complex
because.it involves at least two governmental jurisdictions, Renton and King County, and will
occur on land currently owned by the State. Wetland area associated with a stream drainage will
have some construction impacts. In order to construct the proposed access road (S. 47th Court)
across the subject stream corridor, some fill material will be necessary. Due to access needs, the
impacts are considered to be unavoidable. The proposed wetland/stream road crossing will
require a State Dept. of Fish & Wildlife Hydraulic Project Approval permit (HPA) for work in the
water. This permit will be conditioned with appropriate construction design and,erosion control
measures.
A single, large culvert or several smaller culverts may be used for the road crossing. The
preliminary mapping indicates the proposed wetland fill and piping for the new roadway is
approximately 900 square feet (see attached map). Half of the total wetland area impact,
approximately 450 square feet, will occur within King County on the south side of the new road
right-of-way. The stream channel, on the north side, will be replaced by culvert and the addition
of fill material that is necessary to support the new road.

Mr. Colin Lund -
July 30, 1997

' Due to limited right-of-way width for the access road, the topographic restraints, and the relatively
small impacts, wetland replacement is not being proposed. In order to mitigate for unavoidable
roadway crossing impacts, all disturbed areas be can planted with native wetland and riparian
species. In accordance with King County's Environmentally Sensitive Areas code (Chapter
21 A.24.330), wetland road crossings can be allowed with mitigations that include restoration,
enhancement, or replacement of disturbed areas. The City of Renton may require additional
mitigation for impacts to wetland and stream area.
This investigation and report needs to be verified by the appropriate agencies. If there are any
questions or concerns regarding the wetland/stream investigation or other aspects this report,
please feel free to contact me.

Dear Local Government:
Enclosed is a copy of the recently adopted Washington State Wetland Identification and Delineation
Manual: Also enclosed is a copy of the revised state regulations (WAC 173-22) addressing wetland
delineation.
The 1995 state Legislature (in Senate Bill 5776) required that Ecology adopt into state regulations a
wetlands delineation manual, consistent with the US Army Corps of Engineers (Corps) 1987 manual. All
state and,local governments must now use this delineation manual to implement the state Shoreline
Management Act and local wetlands regulations adopted pursuant to the Growth Management Act. For
those local governments that have adopted either the 1987 or 1989 federal manuals into local regulations, it
is not necessary to revise the local regulations in order to legally require use of the state manual since it is
required by state statute. However,we recommend that you revise the regulations to reference the new
state manual when it is convenient to do so.
Because the delineation manual includes extensive background information, recommended field methods
and technical information, Ecology adopted only the essential,mandatory portions of the manual into state
rules. Ecology added these elements as new sections in an existing rule (Chapter 173-22 WAC, Adoption
of Designations of Wetlands Associated with Shorelines of the State).
The elements of the manual that were adopted into rule are:
1) criteria and indicators for vegetation, soils and hydrology,
• 2)language on problem areas and atypical situations, and
3) an introduction on how to use and apply the manual.
The Washington State Wetlands Identification and Delineation Manual includes all the language in the rule
as well as recommended methods, references and appendices: Wetland delineators will be able to use the
manual in the field. The Corps of Engineers and the Environmental Protection Agency concur that the
state manual is consistent with the 1987 Corps Manual. Anyone conducting a delineation that will need
approval from the Corps and either state or local governments should designate the delineation as being
conducted using the State of Washington Manual and the 1987"Corps Manual. This will meet the
necessary legal requirements of all agencies.
•
Additional paper,copies can be obtained from Ecology's Publication Office by calling(360) 407-7472. We
realize there may be a high demand for multiple copies. However, due to budget constraints,we are
limiting distribution to one copy per request. The document has no copyright and may be duplicated
without requesting permission. Original copies may be downloaded from Ecology's World Wide Web
home page at www.wa.gov/ecology/in the section called"Shorelands and Wetlands."

to thoroughly review the changes. The presentation was made on the application submitted as well as the
alternate layout.
The presentation of the staff report was given by JENNIFER HENNING,Project Manager,Development
Services, City of Renton,200 Mill Avenue South,Renton,Washington 98055. This is an application not only
for a preliminary plat,but for a conditional use permit and a variance in order to build site utilities. This site is
4.55 acres in size,with 2.7 acres being proposed for the subdivision. This property is located east of Talbot
Road and west of 102nd Avenue SE,which is a street in King County, in the Talbot Hill portion of the City. •
There is split zoning on the site. The R-1 zone,which is a low density zone,encompasses a steep slope area on
the western portion. The eastern portion of the site which is to be developed is zoned R-8 and is in the
residential single family Comprehensive Plan(CP)designation.
This parcel is currently landlocked and in order to develop the parcel the applicant would have to extend an
existing street, 102nd Avenue SE,about 200 feet to the north which would end at the point where the City of
Renton and King County boundaries meet. A new street, South 47th Street,would be extended to the west
from 102nd Avenue SE into the site. The property the new street would be located on is currently owned by the
State of Washington Department of Transportation and they are willing to deed over the right of way needed
for this street.
This site has steep slopes that occur on the western portion that range from 25 to 70 percent,and is designated
as a green belt. The eastern portion of the site is flatter ranging from about 5 to 25 percent slopes. There is
extensive vegetation on the site. Applicant has provided geotechnical reports to address the steep slope issues
where the utilities would be constructed,as well as whether or not the homes that were proposed on the western
portion of the developable area would require any special foundations or setbacks and such. The conclusion of
the report was that conventional engineering would suffice.
The new street would be extended into the plat and S 47th Street would end in a cul-de-sac to serve the new 19-
lot plat. There is also a proposal to access some of the lots through a private street system. Lots 1,2,3,4, 5
and 6 would be on a private easement from S 47th Street to the south. There would be a driveway access
easement that would serve Lots 9 and 10 in the southwest corner. Lots 8 and 13,as well as Lots 9 or 10 would
be pipestem lots. The other lots, 7, 8,9, 10, 11, 12, 13, 14,and 15,meet the minimum radius of 35 feet for
location on the cul-de-sac.
This site is zoned R-1 on the west and R-8 on the east. There is a proposal to put a storm water detention vault
at the top of the slope, still within the R-8 area. The proposal includes the extension of utility systems,waste
water and storm water to the southwest corner of the site where there is an existing stub at the Springbrook
Condominiums. Water is being provided by Soos Creek Water District. In order to build S 47th Street from
102nd,there is a drainage swale to be crossed. Because of its size it does not require any special mitigation,but
the applicant is proposing to revegetate the disturbed areas with native and riparian vegetation.
The Environmental Review Committee(ERC)heard this proposal on October 21, 1997. They issued a
Determination of Non-Significance-Mitigated(DNS-M)with six mitigation measures. The applicant was
required to provide additional geotechnical information to determine whether or not the homes that were being
proposed would require special engineering or setbacks. They were required to provide additional detention of
storm water through the 100 year storm event. They will be required to pay the appropriate transportation,

parks and fire mitigation fees,and also to revise their construction mitigation plan to restrict construction-
related traffic to the off-peak hours between 8:30 a.m.and 3:30 p.m.
There is no sewer available in this portion of King County. The only viable choice is to go downslope and tie
into the City system at Springbrook. When the Springbrook project was approved, it was intended that
_ properties to the east would tie into the system;at this location. The City zoned this-area for single family
residential lots at a density of up to 8 units to the acre,minimum lot size of 4,500 square feet. The community
needs to absorb additional growth per the mandates of the Growth Management Act and the only viable way to .
do that is to tie into the existing utility systems down slope.
In order to build the storm water and waste water lines that would connect to the stubs in the Springbrook
Condominium area in the southwest corner of the site,the applicant has proposed a 20 foot wide utility corridor
through the steep slope designated greenbelt area. In order to do that they need to be granted a CUP. There
would be minimal clearing of vegetation. The applicant proposed to install both the waste water and the storm
water line on the surface,but the State Department of Ecology does not permit sanitary sewer systems to be laid
on top of the ground. In this instance the storm water line would be on top of the ground,the waste water line
would be buried. The actual excavation width would be about 6 feet. The remainder of the greenbelt area
would be undisturbed. Staff is recommending that the remainder of the greenbelt area be placed in a native
growth protection easement that would be recorded.
Development of the utility lines to serve this single family plat would be compatible with the existing and
proposed residential scale of the area. There would be minimal disturbance of the slope to construct the utility
systems. The applicant is proposing to place hill-holders or other slope stabilizing mechanisms through the
slope that would ensure the stability of the line. Vegetation would need to be managed over time so that
maintenance could occur,but undergrowth could re-grow in a particular area. The entire corridor would not,
have to be clear at all times.
Staff is recommending approval of the CUP with a condition associated with both the CUP and variance that
the applicant be required to install slope stabilization devices recommended by their engineer.
A variance is needed in order to manage and clear the vegetation in this steep slope area. The clearing which
would occur for the utility lines would tie into the existing sewer stub to the west. There are no other gravity
fed sewer system options existing for this site. The proposed hill holders would help ensure that this project
would not be detrimental to the hillside and it would minimize the impacts to the slope and the greenbelt. All
clearing activities would need to be accomplished in accordance with City codes and policies.
Regarding preliminary plat criteria,this is aproposal for 19 lots and it is within the required density. In this
zone and CP designation, lots are permitted as'small as 4,500 square feet. In this proposal the smallest lot size:
is 4,500 and the largest lot is 5,642 square feet. These are smaller than the existing lots in the area;but they are
compatible with the R-8 designation. The R-8 zone provides for minimum densities of 5 units to the acre and
maximum of 8 units to the acre. The latest calculation takes into account the additional area zoned R-8 to the
west of the site. The 19 lot proposal would result in a density of 7.68 dwelling units per acre. The lots all meet
the minimum size,shape and orientation of the lots with the exception of the pipe stem lots. Because there are
private street approaches for Lots 1 through 6,staff looks at how these lots lay out and the lot actually goes to
the center line of that private street. Regarding minimum width and depth requirements,this application

appears to meet those with some possible fine-tuning of Lots 1 and 6. They may need some additional area to -
meet the setbacks needed from the public street,but it appears there is room to accommodate that. The number
of traffic trips generated from this project would be about 181 new average'daily trips. Applicant has proposed
sidewalks on both sides of the street. South 47th Street leading into the plat would be at full 50 foot right of
way with sidewalks on both sides. In order to extend this street and have a dead-end cul-de-sac at this point,
the Fire Department would require that the street be at full City right of way with 32 feet of travel lane and all
the homes would have to be sprinkled.
One of the biggest concerns for this plat is the precedent it would set for dead-end cul-de-sacs coming into this
parcel from 102nd Avenue SE. It has been recommended that applicant be required to provide a public street
to the south and also to the north;a public street extension that could connect to these other parcels. Applicant
had two options as to how they would be able to provide that plan. Either a 35 foot dedicated right of way on
the eastern property line that would have 28 feet of pavement,sidewalk and curb along the west side of the
street; or.provide 42 feet of right of way within the plat boundaries that would be a fully developed 32 feet of
pavement with curb and sidewalks along both sides with street lighting. That would occur somewhere in the
plat. The rest of the street improvements for the plat have been analyzed by staff and are acceptable as shown
on the preliminary plat submittals. The Fire Department did grant a modification to the dead-end street length
requirement. Typically it is not allowed to have a dead-end street exceed 500 feet without sprinkling or to
exceed 700 feet total. Since this is about 930 feet from its secondary point of access,the Fire Department did
agree if there was a wider access street going in and all the units were sprinkled,that they would support this.
City standards do not support or permit the construction of a private street if adjacent property needs to be
served. If a public street were extended on the site,the area for the public right of way does need to be taken
out from the density calculations and that can affect the overall density.
The site slopes from east to west with severe slopes up to 70 percent. The area that is proposed for
development would be in the 5 to 20 percent range with the steeper slopes occurring on the western portion,
Lots 10, 11, 12 and 13. The project site is vacant along with sites to the north and south. The storm water
would be collected by a tight line conveyance system and would be routed and conveyed to the underground
detention vault just west of Lots 11 and 12. From there the storm water would be tight-lined down the slope to
the west to tie into the existing system in Springbrook Condominium. Talbot Road South does have a system
of storm water ditches. Runoff from about half an acre of the frontage improvements would be conveyed to the
on-site detention facility. There has been localized flooding in the Talbot road area in the past. The ERC did
recognize this and is requiring additional storm water detention through the 100 year storm water event to
minimize those impacts downstream. The appropriate police,fire and recreation facilities are available to serve
this proposal. Renton School District has indicated they would be able to accommodate the number of children
generated from 19 new homes.
Staff would recommend approval of this preliminary plat subject to the following: (1)compliance with the
ERC mitigation measures;(2)drafting of a homeowners association or maintenance agreement to maintain the
common plat improvements such as storm water detention vault,utility and access easements;(3)
establishment of a native growth protection easement for the area on the west that is not included in the utility !
corridor. Staff has recommended modification of the plat to provide a north-south public street,but would like
to revise that to a south public street only. There are extreme slopes to the north with a quarry owned by the
State Department of Transportation,and an extension of a road would basically just fall off. The fifth
recommendation is to modify Lots 1 through 6 in order to meet the zoning and subdivision standards.

Because staff does not know at this point where the public street will be located and its affect on layout of the
lots,their sizes and setbacks, it is a general_recommendation to meet requirements. The applicant is proposing
a private street for Lots 1 through 6 and a public street in a different configuration. This plat generally meets
the City's requirements,but staff feels it is appropriate to require a public street. There have been other plats
which have temporary fire turnarounds that are proposed on lots and at such time when a connection goes
through then those lots could be developed.
Staff is also asking that the applicant be required to submit a tree planting plan that would provide a minimum .
of two street trees to be planted for each lot developed within the plat,or 38 trees. These would be planted in
the right of way and would be street trees approved by the City. They would need to be maintained by the
property owners and/or homeowners association.
The applicant has responded to these recommended staff conditions„with a new lot layout. They are proposing
18 lots by giving up Lot 8. They are keeping their private street for access to Lots 1 through 6. Instead of
having the cul-de-sac in the center of the site, it becomes a temporary cul-de-sac off-site on the adjacent
property to the south. There is no written confirmation that that easement would be granted by the off-site
property owner. In the alternative,the applicant has stated they could pull the turnaround back and at such
point that the property to the south develops,then they could develop Lot 7 as a residential lot. Applicant has
also extended the configuration to the west slightly. Previously the lots were all held back behind the detention
basin. Now Lots 8,9 and 12 would extend to the west slightly. Staff does not have geotechnical information
regarding that extension of Lot 12 to the west.
Colin M.Lund, 11814 115th Avenue NE,Kirkland, Washington 98034,applicant herein,addressed several
items in the staff report. He stated that they had provided and staff had concluded that the density range was 19
lots; Regarding the requirement for Lots 1 and 6 to be corner lots and meet the minimum 60 foot in width,he
stated that after discussions with staff it was concluded that Lots 1 and 6 would not be corner lots. However,
they recognized that additional setbacks may be needed than shown on the plat. A discussion then ensued
among the Examiner, Ms.Henning and Mr. Lund as to the determination of corner lots on public or private
streets.
Regarding the Fire Department right-of-way in the plat,Mr.Lund asserted that a 42 foot right-of-way would be
adequate within the plat boundaries. It would provide the same roadway improvements that a 50 foot right of
way would.
Mr.Lund addressed the conditions of approval. Regarding No.4,he concurred that it would not be possible to
put a road to the north because of the topography,but concurred that a road to the south should be provided.
Condition 6 discusses the density and applicant has provided additional information that based on the plan
submitted 19 lots would be within the permissible density range.
Mr.Lund introduced Exhibit 7,their most recent plat map,and discussed the changes from the previous plat
map. This one indicates,18 lots. The road to the south was extended and required removal of one lot.
Applicant is proposing an offsite temporary cul-de-sac turnaround,but an easement has not yet been secured.
If that option is not available, applicant would locate the cul-de-sac generally in the same location as earlier
proposed. '''

Mr.Lund concluded that the revised layout addressed staffs concerns and recommended conditions and was
an appropriate use of this land.
Jim Gray,Assistant Fire Marshal,City of Renton,200 Mill Avenue South,Renton,Washington 98055, stated
he had not seen the latest plat maps until the previous afternoon and was at a disadvantage to comment.
Normally a cul-de-sac of this length would not be approved without special conditions.
Paul Lumbert,Plan Review,Development Services Division,City of Renton,'200 Mill Avenue South,Renton, •
Washington 98055,explained that the 20 foot utility easement is basically to keep the two utilities separate
from each other,particularly in this case where one is anchored above ground and the other is buried.

The Examiner called for further testimony regarding this project. There was no one else wishing to speak,and
no further comments from staff. The hearing closed at 10:45 a.m.
FINDINGS,CONCLUSIONS &RECOMMENDATION
Having reviewed the record in this matter,the Examiner now makes and enters the following:
FINDINGS: , f
1. The applicant,Jim O'Donnell,filed a request for approval of a 19-lot Preliminary Plat called Talbot
Ridge.
2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation
and other pertinent materials was entered into the record as Exhibit#1.
3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of
Non-Significance-Mitigated(DNS-M)for the subject proposal.
4. The subject proposal was reviewed by all departments with an interest in the matter.
f'.
5. The subject site is located approximately 700 feet west of 102nd Avenue SE. The site is directly west
of SE 184th Street if it were extended to the west(King County street designations).
6. The subject site is an approximately 2.7 acre parcel which is part of a larger 4.55 acre property. The
4.55 acres are divided by a Zoning District boundary that divides the site into the 2.7 acre,R-8 (Single
Family: 8 dwelling units/acre)district and a 1.85 acre,R-1 (Single Family: 1 dwelling unit/acre)
district.
7. The portion of the site which is the subject of this hearing is the R-8 portion,noted above. It appears
that the actual Zoning District line may not have been appropriately located as it was to correspond to
the demarcation between the more level portions of the site and the steep slopes found on the west
portion of the site.
8. The subject site was annexed to the City with the adoption of Ordinance 3268,enacted in December
1978.

9. The map element of the Comprehensive Plan designates the area in which the subject site is located as
suitable for the development of single family residential uses,but does not mandate such development
without consideration of other policies of the Plan.
10. In addition to the general policies found in the Comprehensive Plan there are specific policies
regarding the development of the City's street system, including grid patterns and through access. The
following policies are applicable:
Policy LU-41. Development should occur on a flexible grid street system to the extent •
feasible given environmental constraints. Objective LU-M: Reduce congestion on
arterials and provide more linkages within and between neighborhoods by developing a
system of residential streets which serves both vehicles and pedestrians and creates a
continuous,efficient, interconnected network of roads and pathways throughout the
City.
Policy LU-70. Streets,sidewalks,pedestrian or bike paths in a neighborhood
development should be arranged as an interconnecting network. Cul-de-sacs should be
limited to areas where natural barriers occur. Grid pattern streets are preferable to •
connect adjacent and future development.
11. The subject site is a rectangular parcel. It is approximately 660.18 feet deep(east to west)by
approximately 300.71 feet wide.
12. The approximately one-third westernmost portion of the site has very steep slopes approaching 70
percent. The remaining site has slopes that vary from 10 percent or less(the eastern half(Proposed
Lots 1-8 and 16-19))up to 20 percent for the middle section of the site.
13. The site was reviewed for wetlands on two occasions. The report found a small creek that runs north to
south east of the actual site but in the area where the access road would be developed. A small,
approximately 1,800 square foot wetland was identified. It is a Class 3 because of its small size and
limited habitat.
14. The main access to the site would be a cul-de-sac public roadway. In order to provide access to some
of the resulting parcels that would lack frontage on a public right-of-way,the applicant has proposed
creating a private north-south street to serve proposed Lots 1-6 and a roadway for Proposed Lots 9 and
10 over a separate Tract A. Proposed Lots 1 and 6 would actually front on the new public street but
would gain access from the proposed private street.
15. The applicant proposes dividing the subject site into 19 single family lots ranging in size from
approximately 4,500 square feet to 5,642 square feet.
16. Staff noted that the location of the site coupled with limited access to other parcels would require the
applicant to create a public street extending to the south. This requirement would reduce the number of
lots to 18 or less.
17. Staff also noted that the creation of a tract,Tract A, is not permitted but that a pipestem to one or both
and an easement to the other would be acceptable.

18. The proposed cul-de-sac extends beyond the 500 foot"dead-end"length permitted by the Fire
Department. It is acceptable as long as the homes are provided with sprinkler systems and the roadway
has a 32 foot wide paved roadbed and sidewalks on one side of the off-site street improvements.
19. The applicant submitted some alternative plat layouts that would extend a road south from the vicinity
of the now proposed cul-de-sac. One would extend the roadway to the south creating the actual cul-de-
sac bulb on the adjoining lot to the south. No formal agreement for use of this adjoining parcel has
been executed. Another proposal would extend the roadway south from the cul-de-sac creating an
easement for the bulb that could be dissolved allowing lot development in the future.
20. The nearest practical sewer connection is west of the site well down the steep slopes. Another
development was required to install a City sewer stub to eventually serve the area in which the subject
site is located. Similarly, storm water would need to be conveyed over and down the steep slope to a
City facility.
21. These lines will disturb the steep slope which is designated Greenbelt in the Comprehensive Plan. A
Conditional Use Permit is required to install utility lines in designated Greenbelts. In addition,the
removal of vegetation on these slopes requires a Variance under the Land Clearing and Tree Cutting
Ordinance.
22. The utility corridor will be 20 feet wide. State law requires sanitary sewer lines to be buried. The
storm water line will be aligned along the surface. The applicant will be clearing only as much of the
slope as necessary to dig its trench and bury the line. The slope would be re-stabilized with techniques
including"hill holder" devices. The slope would also be replanted to prevent erosion although the
vegetation would be such as to prevent interference with the operation or maintenance of the utility
lines. -
23. The development of the subject site would generate approximately 9.55 daily vehicles trips per
dwelling. The proposed 19 dwelling units would generate approximately 181.45 trips overall. Staff
has indicated that the underlying road system can handle this traffic. Eighteen lots would generate
approximately 170 trips.
24. Development of the subject site will generate approximately 14 students. They will be spread over the
grades of the Renton School system which apparently has sufficient capacity. -
25. The new roadway will'run north and then west to the subject site. It will be located in both the City and
King County. It will cross State land. The State has indicated a willingness to dedicate the right-of-
way to the City. There will be approximately 980 lineal feet of roadway constructed between the
subject site and the existing road, SE 102nd Street. The new roadway will continue SE 102nd Street
north for approximately 280 feet,then will turn west where it will be South 47th Street in Renton. This
leg will be 700 feet in length. As noted, it will have a 32 foot wide road surface to provide emergency
access vehicles adequate room. Two overall widths were noted in the staff report.
26. Staff has recommended that the applicant submit a plan showing the planting of street trees.
27. A geotechnical analyses demonstrates that homes and detention system may be placed along the top of
the slope as long as certain construction standards are complied with by the applicant.

CONCLUSIONS:
Greenbelt Encroachment Conditional Use Permit
1. The applicant for a Conditional Use Permit must demonstrate that the use is in the public interest,will
not impair the health, safety or welfare of the general public and is in compliance with the criteria
found in Section 4-31-36(C)which provides in part that:
a. The proposal generally conforms with the Comprehensive Plan; •
b. There is a general community need for the proposed use at the proposed location;
c. There will be no undue impacts on adjacent property;
d. The proposed use is compatible in scale with the adjacent residential uses, if any;
e. Parking,unless otherwise permitted,will not occur in the required yards;
f. Traffic and pedestrian circulation will be safe and adequate for the proposed project;
g. Noise, light and glare will not cause an adverse affect on neighboring property;
h. Landscaping shall be sufficient to buffer the use from rights-of-way and neighboring property
where appropriate; and
i. Adequate public services are available to serve the proposal.
The requested conditional use appears justified.
2. While the Comprehensive Plan designates the site for Greenbelt or low density single family uses,that
does not completely exclude the development,with reasonable protections,of utility corridors. In
addition,the Greenbelt regulations permit utility lines. The intrusion should be minimal although the
storm water line will be above the surface. Clearly a surface line will create a visual intrusion but
minimizes the disturbance of the underlying soils and the vegetation.
•
3. Whether there is a community need for this line is a matter of timing: This site is "hostage"to access to
utilities. The only utilities are those down below the steep slopes. If there is a community need for this
particular development and its additional housing,then there is a need for the utility lines to be
extended down a steep slope and across a designated greenbelt. It would appear that until lines are
brought in from the east,the subject site,which is zoned for eight dwelling units per acre;could not be
developed as envisioned in the Comprehensive Plan. One could argue that the Comprehensive Plan did
not truly understand the nature of this area. Property to the east of the site along the plateau is actually
less developed than the areas below along Talbot Road. Therefore,the only practical,current solution
is the proposed corridor.
4. The development of the site, if managed appropriately so that erosion or slippage does not occur,
should not affect adjacent property. The two lines are a minimal intrusion and slope restoration and _
vegetation should eventually screen the refilled sewer trench and soften the appearance of the above-
ground storm line.

5. The line itself should not generate much traffic after construction activity,only periodic maintenance or
inspections,and not be out of scale due to the nature of the project. There should not be any
unacceptable noise, light or glare once construction is completed.
6. The slope will be replanted with appropriate materials to prevent slippage or erosion but allow
maintenance.
Land Clearing Variance •
7. Variances may be granted when the property generally satisfies all the conditions described in part
below:
a. The applicant suffers undue hardship caused by special circumstances such as: the size, shape,
topography,or location where code enforcement would deprive the owner of rights and
privileges enjoyed by others similarly situated;
b. The granting of the variance would not materially harm either the public welfare or other
property in the vicinity;
c. The approval will not constitute a special privilege inconsistent with the limitations on other
property in the vicinity;and
d. The variance is the minimum variance necessary to allow reasonable development of the
subject site.
The applicant's property appears ripe for the variance requested.
8. It appears that the only reasonable corridor for the two utility lines is across the vegetated steep slope.
The location of the site makes any other route impractical since there are no sewer lines to hook up to
other than the one below the slope. Additionally,the storm line needs gravity which necessitates
dropping the storm line over the bank and down the slope.
9. The approval will alter the natural surface of the site,but if done a correctly should not cause any long
term harm to neighboring properties or the public welfare.
10. The approval should not grant the applicant a special privilege. The lines will be available•to serve
other nearby properties,reducing the need for similar intrusions into other areas along this slope. In _
addition,the unique circumstances should limit the precedent created by granting this variance.
11. The land clearing should be limited to the immediate vicinity of the two lines. The trenched line will
require more width but will not require the removal of vegetation from the entire easement width. The
surface line will require less ground disturbance. The areas disturbed will be the minimum necessary
to accomplish the work.

G'
12. The proposed plat, subject to the conditions noted below,appears to serve the public use and interest.
Although it might be premature to develop the subject site due to the need to step around a variety of
1 I .

limitations, staff has noted that the proposal is compatible with the Comprehensive Plan and Zoning
which both call for up to 8 homes per acre. The development will provide additional housing choices
although extending services to this area does require both a Conditional Use and Variance to provide
the site with sanitary and storm water systems. In addition,an access road must be extended without a
master plan of where the street grid system will be located which will ultimately serve the site and
surrounding area.
13. The plat represented by Exhibit Number 7 with the Exhibit Number 8 overlay shall be the plat that is
developed for this project if it can be demonstrated that it meets the necessary code provisions for lot •
area and setback for front yards and corner lots. The cul-de-sac shall be created solely on the subject
site and the off-site cul-de-sac is not approved. Preliminary Plat approval is not speculative. While
modest alterations might be accommodated, a specific plan for streets as well as the various utilities is
necessary for the approval of a Preliminary Plat. It is inappropriate to approve a conjectural plan at this
time. In addition, since development of the adjacent properties may not occur for a long period of time,
any cul-de-sac may be a long term access requirement. Therefore,while it may be created as an
easement which may be dissolved if the roadway is extended creating a through grid pattern, all lots
shall have sufficient lot area exclusive of any such easement at this time. That is,all lots lying around
the cul-de-sac shall contain 4,500 square feet exclusive of any easement property. This is similar to the •
requirement that all lots shall have the minimum lot area exclusive of any pipestem access. Again;any
extension that creates a,through street system could be years off and all lots should have the minimum
lot area as well as front, side and rear yard areas.
14. The creation of a separate legal tract to provide access to interior lots is inappropriate,creating
• maintenance and ownership complications that can be avoided. The applicant shall provide the
appropriate access to any interior lots over an easement roadway and not a separate tract.
15. The private street to provide access to Proposed Lots 1 -6 appears reasonable,although a more long-
term street grid system probably should have been carefully analyzed so that the applicant would have
had more information on which to base some of their plat decisions.
16. Since access to the site is basically a long dead-end street and emergency access in such a.situation is
very important,all rights-of-way within the site shall be developed to the City's 50(fifty)foot roadway
standards.
17. The lots appear to be as rectangular as possible given the need for a cul-de-sac bulb to accommodate a
turnaround location and emergency access.
18. The development will increase the tax base of the City. It appears that utility services can be extended
to serve the site.
19. As staff has suggested,the applicant shall submit a tree planting plan showing a minimum of two(2)
street trees for each lot,although the distribution shall be altered as determined by the City.
20. In conclusion,while many aspects of the plat still appear vaguely defined,the concept after staff
calculates the lot area,yard setbacks and appropriate zoning demarcation,generally appears to serve
the public use and interest. The matter will not be forwarded to the City Council for review until a plat
has been submitted to staff which meets all requirements and said plat has been submitted to the
Hearing Examiner with a written statement indicating that each lot meets'all City standards within sixty

(60)days of publication. If such a plat and written documentation is not submitted in a timely fashion,
the matter will be reopened for additional public hearing.
DECISION AND RECOMMENDATION
The Conditional Use Permit and Variance are approved,as is a Preliminary Plat for 16 to 18 lots
subject to the following conditions:
1. The preliminary plat map demonstrating the appropriate aspects of Exhibits 7 and 8 shall be
resubmitted for review by staff who shall forward said plat and written documentation indicating that
each lot meets all City standards within sixty(60)days of publication. If such a plat and written
documentation is not submitted in a timely fashion,the matter will be reopened for additional public
hearing.
2. All lots shall have sufficient lot area exclusive of any easement. That is,all lots lying around the cul-
de-sac shall contain 4,500 square feet exclusive of any easement property.
3. All public rights-of-way within the site shall be developed to the City's 50(fifty)foot roadway
standards. The cul-de-sac shall meet all turning radii standards. I'
4. The applicant shall submit a tree planting plan showing a minimum of two(2)street trees for each lot,
although the distribution may be altered as determined by the City. The applicant shall post a bond to
assure compliance with this condition.The City shall be responsible for planting the trees.
5. All land clearing both in the plat and particularly along the steep slopes shall be as limited as possible.
In the steep slopes all clearing shall be limited as much as practical to the immediate vicinity of the two
utility lines.
6. The applicant is required to comply with the mitigation measures which were required by the ERC
prior to the issuance of a construction or building permit. p
7. The applicant shall draft and record a maintenance agreement or establish a homeowner's association
for the maintenance of all common plat improvements(storm water detention vault, utility easements,
access easements). A draft of the document shall be submitted to the City for review and approval by
the City Attorney prior to the recording of the plat.
8. The applicant shall define and record a Native Growth Protection Easement on the face of the plat for
the steep slope areas west of the storm water detention vault. The applicant shall adhere to the City j p
code requirements for such areas.
9. The access tract shown for any lots shall be eliminated and that area incorporated into one of the lots as
a pipestem,with an access easement for the other lot.
10. The applicant shall be required to install slope stabilization devices as recommended by the applicant's
engineer or geotechnical consultant.

TO: Fred Kaufman,Hearing Examiner
FROM: Gregg Zimmerman 6'
SUBJECT: Talbot Ridge Preliminary Plat(LUA-97-087,PP,CU-H,V) —Request
for Clarification/Reconsideration•
I have read your decision and recommendation of December 4, 1997 for the proposed Talbot Road
Preliminary Plat. Condition No. 1 states that the preliminary plat map shall be resubmitted for review
by staff "within sixty (60) days of publication." It appears that the publication referenced is the date
of the Hearing Examiner's decision, however, it could be interpreted differently. Please clarify this
condition.
Condition No. 2 states that: "All lots shall have sufficient lot area exclusive of any easement. That
is, all lots lying around the cul-de-sac shall contain 4,500 s.f. exclusive of any easement property."
This condition requires additional clarification. Does the condition pertain to "any" easement
including franchise utilities, City systems, access easements, drainage features, and the like? Or, was
the intent of the condition only for the access easement associated with the proposed cul-de-sac?
Condition No. 3 states that: "All public rights-of-way within the site shall be developed to the City's
50 (fifty) foot roadway standards. The cul-de-sac shall meet all turning radii standards." City Code
Section 4-34-11:D allows a reduction of required right-of-way by the Department Administrator for .
new residential access streets within a subdivision "to forty-two feet (42') when the extra area from
the reduction is used for the creation of an additional lot(s) which could not be platted without the
reduction; or when the platting with the required right-of-way width results in the creation of lots with
less than one hundred feet (100') in depth. The Department may require additional easements be
provided for the franchise utilities outside of the dedicated right-of-way when such a right-of-way
reduction is approved. In no case shall a reduction in the required right-of-way be approved unless it
is shown that there will be no detrimental effect on the public health, safety or welfare if the right-of-
way is reduced,and that the full right-of-way width is not needed for current or future development."
With a reduced right-of-way width of 42-feet,'the resulting travel lane is 32 feet, the same width of
travel lane as would occur with a 50-foot-wide right--of-way. I understand that the Fire Prevention
Bureau was concerned about adequate roadway width, turning radii, and turnarounds. Please clarify
whether you would permit the applicant to apply for a reduced right-of-way per Code Section.4-34-
11:D.
Condition No. 4 requires the applicant to submit a tree planting plan showing a minimum of two (2)
street trees for each lot,with the possibility of the distribution being altered as determined by the City.
The requirement would result in 32 to 38 trees being planted in association with the plat. Planting of
trees on the individual lots, or in the right-of-way adjacent to the lots would not be practical, since
many of the new lots have narrow street frontage,frontage on an access easement, or driveways taking
December 17, 1997
Page 2'
up much of the street frontage. The preference of the Planning/Building/Public Works Department
(PB/PW) is to require the planting of the required trees in the right-of-way for the new public street
(South 47th Street). The trees could be installed along with other street improvements and prior to the
recording of the plat. Therefore, no surety device or bond would be necessary. We rarely bond for
required landscaping, unless a deferral is granted, and I would not support it for this project. In
addition,I strongly yet respectfully disagree with the second portion of the condition requiring the City
to plant the trees mitigating impacts of private developmnet. We do not have the personnel to
accomplish this, and it would set a precedent for other plats,that is not supported by this Department.
Again, if the street trees were installed by the applicant/developer in conjunction with required street
improvements,this could be accomplished in a timely manner,and prior to recording of the plat::
In summary, I am requesting clarification of Conditions No. 1, 2, and 3, and reconsideration of
Condition No. 4. Please do not hesitate to contact me if you have questions regarding this
correspondence.

Re: Request for Clarification/Reconsideration regarding
Talbot Ridge Preliminary Plat,File No. LUA97-097,PP,CU-H,V
Dear Mr. Zimmerman:
I have reviewed your requests for clarification and reconsideration in the above matter.
Condition No. 1
As you might expect,the date that the decision was issued is the date of publication mentioned in
Condition No. 1.
Condition No. 2
Condition No. 2 is not intended to exclude the normal utility easements for water, sewer or
private gas, electric,phone or cable TV lines. It was intended to refer to access easements and
the proposed cul-de-sac.
As you might expect,when an application is as sketchy as this one(with changes submitted
during the public hearing),.there,are few concrete details upon which to base a decision,requiring
instead the necessarily vague attempts to define what is not accurately represented in any of the
submissions or exhibits. This lack of both detail and staff review of the late submissions by the
applicant is what gives rise to the Condition No. 1 where this office needs the assurance that the •
plat actually does meet code requirements.
•. Condition No. 3
The plans were submitted with the larger road dimensions and those were the plans reviewed.
The changes should have been made prior to the public hearing in order for them to have been -
considered. Like other aspects of this application,too much was left for conjecture or altered
after staff review,making some aspects of review quite problematic. This is not to say that
modifications after staffs recommendations should be out of the ordinary,but some aspects of •.
this plat were clearly unacceptable and should have been refined prior to the public hearing.
Condition No. 4
--This office adopted the staff recommendation in regards to the number and general arrangement
of the street trees. This office will modify the decision to accept any legal method that assures
200 Mill Avenue South - Renton, Washington 98055 - (206)235-2593
,
I'.
•
that the trees are bonded and installation accomplished. The condition requiring the planting was
to insure that the City act on the bond or other legal guarantee as it would any other bonded
obligation, either contracting out the installation of the improvements as they would street
lighting or similar improvements, or making sure the work is completed.
This office hopes this letter appropriately addresses your concerns regarding this application.
Sincerely,
Fred J. Kaufman

Re: Talbot Ridge Preliminary Plat
LUA97-087,PP,CU-H,V .
Dear Jennifer:
This office has reviewed the latest submittals from the applicant and staff. It appears that most of the
pre-conditions have been satisfied regarding lot and road dimensions.
There is still a concern over creating Tract C. This would provide a separate tract that would be used to
accommodate the cul-de-sac bulb. Since there is no time-frame in place for the expansion or connection
of the road system to create a through street,the tract could be in existence for a long period of time.
That raises the possibility that the portions of the tract not occupied by road will slip into a non-
maintained appearance. If ownership were to remain with the applicant,there would be no way to
burden the remaining homeowners with the costs or responsibilities to maintain the excess property.
Therefore, it should be added to Proposed Lot 3,remaining subject to the easement for the cul-de-sac
bulb. If the road is eventually extended and the cul-de-sac abandoned,then that portion of enlarged Lot
3 can be segregated according to the then existing zoning standards. Therefore,Tract C should be
eliminated and made part of Proposed Lot 3.
There does not appear to be any reason to complicate the plat or legal descriptions by creating a Tract B,
which appears to be part of and subject to the same Native Growth Protection Easement standards as the
much larger Tract A. It is merely separated by an easement. It should be eliminated and incorporated
into Tract A. The homeowners shall be clearly responsible for the maintenance of the Native Growth
Protection Easement and it shall not be sold or developed other than for the currently proposed utility
easement.
It appears that the discrepancy in the legal description has been rectified:
With the submission of a Plat map incorporating Tract C into Lot 3 and the consolidation of the Native
Growth area into one tract,the plat can be submitted to the City Council.
If this office can be of further assistance,please feel free to write.
Sincerely,
t ` J(..
