properties are designated in the Tigard Comprehensive Plan for Low and
Medium-High Density Residential development.
4. Site Information and Proposal Description
The Sensitive Lands Permit is required for the sewer line proposed
below the 140 elevation or within a drainageway. The area between 128
and 140 feet in elevation is identified as a significant wetlands area
in the Comprehensive Plan. The and above 140 feet is within a
drainageway.
STAFF REPORT -- SL 9--86 - PAGE 1
The Unified Sewerage Agency is proposing to install a 12 inch, public
sewer line between the existing pump station on the north side of
Durham Road (which will be removed after completion of this line) to
the existing portion of the line that is approximately 1,900 feet to
the south. The elevation of the line will range from 130 to 175 feet.
This line was contemplated in conjunction with the Summerfield
development and the pump station is viewed as an interim solution for
sewerage disposal. The northern section of they line will be within the
City and the remainder will traverse County properties. During
construction, a 50 foot wide area will be cleared of brush but larger
trees are to be avoided to the greatest extent possible. The
construction area will be reseeded immediately following construction.
5. (Agency and NPO Comments
The Engineering Division has no objection to the proposal, provided the
recommended conditions of approval are met.
The Building Inspection Office, NPO #6, and Washington County
Department of Land Use and Transportation have no objection the request.
No other comments have been received .
B. FINDINGS AND CONCLUSIONS
Development in the ravine area between 120 and 140 feet is subject to
the following standards in Section 18 .84.045 of the Code:
Exception for Development in the 108th/113th Ravine Significant
Wetlands Areas .
(a) Under the Sensitive Lands Permit process, the Hearings
Officer may allow portions of the Ravine at 108th and 113th
designated as a significant wetlands area to develop
provided that all of the following criteria are met.
(1) All of the land (within the ravine) being considered
for development is at less than 25% slope.
(2) There are no unstable soil conditions on the land
being considered for development.
(3) The provisions of Chapter 18 . 150— TREE REMOVAL shall
be met.
Development in the northern remainder of the drainageway is subject to
the following requirements that are found in Section 18.84.040 of the
Code:
(c) The Hearings Officer shall make findings that all of the
following criteria are satisfied when approving, approving
with conditions or denying an application request for a
Sensitive Lands Permit within drainageways:
STAFF REPORT - SL 9--86 -- PAGE 2
(1) The extent and nature of the propo.nd land form
alteration or development will not create site
disturbances to the extent greater than that required
for the uses;
(2) The proposed land form alteration or development will
not result in erosion, stream sedimentation, ground
stability or other adverse on—site and off—site
effects or hazards to life or property;
(3) The water flow capacity of the drainageway is not
decreased; and
(4) Where natural vegetation has been removed due to land
form alteration or the development, the areas not
covered by structures or impervious surfaces will be
replanted to present erosion in accordance with
Section 18 . 100 (LANDSCAPING AND SCREENING) .
The proposed sewer line installation can satisfy the above criteria
because of the factors below:
1. The bottom portion of the drainageway has a slope of less than 25
percent and the steeper side slope areas will be avoided.
2. There is no evidence of slope instability and replanting and soil
stabilization measures will be taken.
3 . The cutting trees over 6 inches in diameter will be avoided to
i-ne maximum extent possible as required by Chapter 18 , 150 of the
Code.
4 , The area of work and soil disturbance will be held to a minimum
and will be limited by the width of the easement.
5. The terrain will be virtually unchanged before and after
construction and the present water carrying capacity of the
drainageway will retained .
C. RECOMMENDATION

following conditions:
1 . That construction of the proposed sanitary sewerage improvement
shall not commence until posting of a 100% performance bond,
payment of public improvement plan check and inspection fees and

A. FACTS
1 . General Information
CASE: Sensitive Lands Permit (SL 9 -86)
REQUEST: To allow construction of a sewer line within the
108th/113th Avenue ravine.
COMPREHEN:'','7_ ''i_AN DESIGNATION: Medium High and Low Density
Residential
ZONING Dr_SIGNATION: R-25 (Residential 25 units/acres
APPLICANT: Unified Sewerage Agency OWNER: See Application
150 N. 1st Avenue
Hillsboro, OR 97214
LOCATION: Immediately south of SW Durham Road and west of SW 108th
Avenue.
2. Background Information
A previous application was approved in 1985 (File No. SL 2-85) to
construct the southern portion of their sewer line.
3. Vicinity Information
The area involved in this application is within the City near Durham
Road and the southern section of the proposed line is within Washington
County . The property within the City is zoned R- 7.5 and the County
properties are designated in the Tigard Comprehensive Plan for Low and
Medium—High Density Residential development .
4 . Site Information and Proposal Description
The Sensitive Lands Permit is required for the sewer line proposed
below the 140 elevation or within a drainageway. The area between 128
and 140 feet in elevation is identified as a significant wetlands area
in the Comprehensive Plan. The land above 140 feet is within a
drainageway.
STAFF REPORT -- ;L 9-86 -- PAGI 1
The Unified Sewerage Agency is proposing to install a 12 inch, public
sewer line between the existing pump station on the north side of
Durham Road (which will be removed after completion of this line) to
the existing portion of the line that is approximately 1,900 feet to
the south. The elevation of the line will range from 130 to 175 feet.
This line was contemplated in conjunction with the Summerfield
development and the pump station is viewed as an interim solution for
sewerage disposal. The northern section of tho line will be within the
City and the remainder will traverse County properties. During
construction, a 50 foot wide area will be cleared of brush but larger
trees are to be avoided to the greatest: extent possible. The
construction area will be reseeded immediately following construction.
5. Agency and NPO Comments
The Engineering Division has no objection to the proposal, provided the
recommended conditions of approval are met.
The Building Inspection Office, NPO #6, and Washington County
Department of Land Use and Transportation have no objection the request.
No other comments have been received.
B. FINDINGS AND CONCLUSIONS
Development in the ravine area between 128 and 140 feet is subject to
the following standards in Section 18 .84.045 of the Code:
Exception for Development in the 108th/113th Ravine Significant
Wetlands Areas .
(a) Under the Sensitive Lands Permit process, the Hearings
Officer may allow portions of the Ravine at 108th and 113th
designated as a significant wetlands area to develop
provided that all of the following criteria are met.
(1) All of the land (within the ravine) being considered
for development is at less than 25% slope.
(2) There are no unstable soil conditions on the land
being considered for development.
(3) The provisions of Chapter 18 . 150- TREE REMOVAL shall
be met.
Development in the northern remainder of the drainageway is subject to
the following requirements that are found in Section 18.84.040 of the
Code:
(c) The Hearings Officer shall make findings that all of the
following criteria are satisfied when approving, approving
with conditions or denying an application request for a
Sensitive lands Permit within drainageways:
STAFF REPORT - SL 9--86 - PAGE 2
•
(1) The extent and nature of the propo*nd land form
alteration or development will not create site
disturbances to the extent greater than that required
for the uses;
(2) The proposed land form alteration or development will
not result in erosion, stream sedimentation, ground
stability or other adverse on-sits and off-site
effects or hazards to life or property;
(3) The water flow capacity of the drainageway is not
decreased; and
(4) Where natural vegetation has been removed due to land
form alteration or the development, the areas not
covered by structures or impervious surfaces will be
replanted to prevent erosion in accordance with
Section 18. 100 (LANDSCAPING AND SCREENING) .
The proposed sewer line installation can satisfy the above criteria
because of the factors below:
1 . The bottom portion of the drainageway has a slope of less than 25
percent and the steeper side slope areas will be avoided.
2. There is no evidence of slope instability and replanting and soil
stabilization measures will be taken.
3 . The cutting trees over 6 inches in diameter will be avoided to
i-ne. maximum extent possible as required by Chapter 18 . 150 of the
Code.
4 , The area of work and soil disturbance will be held to a minimum
and will be limited by the width of the easement.
5. The terrain will be virtually unchanged before and after
construction and the present water carrying capacity of the
drainageway will retained .
C. RECOMMENDATION
The Planning staff recommends approval of SL. 9- 86 subject to the
following conditions:
1 . That construction of the proposed sanitary sewerage improvement
shall not commence until posting of a 100% performance bond,
payment of public improvement plan check and inspection fees and
execution of (and City acceptance of) a construction compliance
agreement .
2. That construction of the proposed sanitary sewerage improvement
shall occur between April 30th and October 1st, 1985, unless
written permission is received from the City Engineer.
STAFF REPORT SL 9-86 -- PA(;I1
3 . Erosion control shall be applied through the course of
construction and, further, a temporary (before and during
construction) and permanent (after construction) erosion control
plan be submitted as part of the public improvement plans to be
approved by the City Engineer.
4. Three (3) sets of plan—profile public improvement construction
plans and one (1) copy of construction agreement, stamped by a
Registered Professional Civil Engineer, detailing all proposed
public improvements shall be submitted to the Engineering Section
for approval .
5. A plan showing the location of all trees over 6 inches in
diam±ter that are to be removed shall be approved by the Planning
Director.
6. This approval is valid if exercised within one year or the final
decision date.
