Project Understanding
Summer Lake is a valued open water feature in Washington County. It provides
aesthetic appeal to Summer Lake Park and to residences surrounding the park.
Summer Lake, however, is an impoundment of water in an urban drainage. Water
' quality concerns typically associated with urban drainages include, high temperatures
and excessive nutrients from runoff. When water from an urban drainage is
impounded behind a dam, these water quality problems become exacerbated due to
' increased solar input and the cycling of nutrients to provide conditions where algae,
bacteria and aquatic weeds flourish.
' Alga blooms and aquatic weeds have reduced the aesthetic appeal of Summer Lake. So
much so, that nearby residents are requesting action to clean up the lake. Nearby
residents are not the only stakeholders concerned about the water quality of Summer
' Lake. The Oregon State Department of Environmental Quality (DEQ) is also concerned
about the water quality of Summer Lake. Summer Creek, which was dammed to form
Summer Lake, is part of the Fanno Creek and Tualatin River Watershed. These streams
' and rivers are designated "Water Quality Limited" by DEQ who enforces compliance
with the Clean Water Act at the state level. Water quality constituents of particular
' concern include total phosphorous, ammonia, temperature, E. coli bacteria, dissolved
oxygen, and chlorophyll-a. It is generally accepted that impoundments of water
generate a negative effect as related to all the water quality constituents listed as
concerns for Summer Creek. This is recognized in the Fanno Creek Watershed
y Masterplan,which recommends restoring Summer Creek to a free flowing state.
Regulatory issues are further complicated since Summer Creek provides habitat for
Steelhead Trout and Coho Salmon,both of which are listed as threatened species under
the Endangered Species Act (ESA). As such, Unified Sewerage Agency (USA) who
manages surface water quality in Washington County will be forced to comply with
two very large regulatory hammers, the Clean Water Act and the Endangered Species
Act. The time to improve the water quality of Summer Creek and Summer Lake is a
' hand.
Project Approach
' Our project team possesses the experience and knowledge to successfully accomplish
the alternatives development and selection phase of this project and carry the project
through design and construction of the preferred alternative. Inter-Fluve, Inc. is a
' multidisciplinary firm that has developed an excellent reputation for restoring streams,
lakes and wetlands. HDR, Inc. provides exceptional expertise related to water quality,
engineering and management of large-scale projects. Jeanne Lawson Associates (JLA)
' provides unsurpassed public involvement expertise to the project team.
The initial phase of this project will largely rely on the skills of the team's public
' involvement consultant JLA, with Inter-Fluve developing alternatives and HDR
providing expertise related to cost and construction of the alternatives. The consensus
building and group decision facilitation skills of JLA are paramount to the successful
completion of the initial phase on time and within budget. Inter-Fluve and HDR will
provide the necessary technical expertise to evaluate the feasibility of alternatives.
Inter-Fluve worked successfully with JLA on the Fanno Creek Watershed Masterplan,
and is currently working with JLA on the OES Marsh Enhancement for USA.
' As the project evolves beyond alternatives selection, Int r Fl v and HD� will assume
more active roles related to design, construction and QA/QC of theZnd
ect. HDR and ;A
Inter-Fluve teamed together to provide design, bid document construction
' oversight services for the Oregon Garden Wetlands in Silverton, OR. It is anticipated
that Inter-Fluve and HDR will approach this project in a similar manner as we
approached the Oregon Garden Wetlands. That is, Inter-Fluve utilizing a collaborative
design approach drawing on the diverse scientific and engineering backgrounds of our
staff, and HDR providing QA/QC related to design, construction and bid document
preparation.

Project Descriptions
1 Goldsboro Dam, Shelton,Wasington
Evaluated five bioengineered bank stabilization alternatives considered for
rehabilitation to allow fish passage to the upper watershed following dam removal.
' Evaluation included hydraulic model analysis using HEC-RAS. Developed preliminary
designs and alternatives analyses that were submitted to the Army Corps of Engineers
for their use in the dam removal project. Alternatives were evaluated based on
erosional resistance and cost.

Ocklawaha River, Daytona, Florida.
Construction of the Rodman Reservoir in the early 1960's resulted in the inundation of
approximately 22 miles of river channel, in addition to several tributaries and
' thousands of acres of floodplain. Much of the former densely vegetated floodplain had
been cleared by crushing the forest into the wet soils, or by cutting and clearing the
trees into windrowed berms. To facilitate barge traffic across the reservoir, a straight
canal was cleared and partially excavated by dredge through the floodplain with spoils
deposited along either side. The canal was excavated across the Deep Creek channel, a
tributary to the Ocklawaha River, and through a portion of the meandering planform of f t tom.
the Ocklawaha River. Construction of the canal also severed the channel of Camp LSV
Branch, a tributary to the Saint Johns River. The current Florida Legislature decided to ��RG
decommission and remove the Rodman dam thus restoring the Ocklawaha River to a
' free flowing condition.
Inter-Fluve was responsible for the preliminary design for the restoration or
' reconstruction of the Ocklawaha River channel and floodplain as well as the channels of
Deep Creek and Camp Branch. Inter-Fluve was a member of the design team to prepare
the permit application for the removal of the Rodman Dam and Reservoir. The project
' included the restoration of approximately 26 miles of channel and the reconstruction of
approximately 5900 feet of channel. This work is required to limit the potential for
channel erosion or avulsion with an increased sediment load in the Ocklawaha River
when flow is reestablished in the denuded channel and floodplain. Since the floodplain
is inundated much of the year, restoration and reconstruction work was designed to be
' performed from barge mounted equipment.

The Oregon Garden, Silverton, Oregon.
Inter-Fluve,Inc. led the effort to design and construct 21 acres of wetlands for this
benchmark,world class botanical garden that also serves as a wastewater polishing
' facility for the City of Silverton Oregon. Inter-Fluve,Inc. participated in the site master
plan and predesign efforts as well.
The wetlands are located on the same site as a botanical garden; thus,aesthetics were a
high priority throughout the design process. Inter-Fluve,Inc. worked closely with
several landscape architecture firms to produce a design that fit with the vision of the
garden master plan. Part of this vision included arranging the wetlands in a terraced
configuration as water flowed down through the site. This terraced configuration
imposed several design challenges related to the stability of earth fill volumes used to
1 impound water within individual wetland cells. An extensive planting plan was
produced considering wetland functionality, aesthetics, and public display of wetland
vegetation with education as a focus.
Water quality was also a primary concern. Although the water entering the site will be
highly treated,nutrient concentrations are considered relatively high compared to most
surface waters. In addition,Oregon statutes do not allow any degradation to ground
water quality. The primary water quality constituents of concern were nitrogen and
r
' hos horous compounds. i t i
p pNitrate,ate,n trogen freely flows through groundwater,
whereas dissolved phosphorous will bind to soil. Nitrate concentrations were predicted
to be effectively reduced within the first two wetland complexes,while phosphorous
concentrations were predicted to remain relatively high. The design solution included
lining the first two wetland complexes, and leaving the third (largest) wetland complex
unlined. This way,nitrate concentrations will be reduced before allowing contact with
groundwater, and dissolved phosphorous will be encouraged to bind to soils beneath
the last wetland complex. A series of subsurface drains that can discharge to the surface
of the next, lower, cell were installed in the unlined wetland complex to allow for
operational flexibility

Whatcom and Hannah Creek Emergency Restoration, Bellingham,Washington
Inter-Fluve was retained by Equilon Enterprises to provide emergency design and
construction oversight services for the repair and restoration of a portion of Whatcom
Creek damaged by a ruptured pipeline and subsequent explosion in June of 1999.
During cleanup efforts,the channel bed was highly disturbed and lost its natural bed
morphology. Inter-Fluve provided re-constructive and enhancement designs.
Following design, Inter-Fluve directed emergency channel re-construction activities
while using on site and imported large wood to enhance habitat. Channel work
included construction of lateral and channel spanning log jams in step pool
morphology,pool riffle construction in downstream alluvial reaches, and step pool
excavation and enhancement. The channel enhancement repaired a previously known
low flow passage problem at Woburn bridge. All work was completed under critical
time parameter due to salmon spawning season. Project monitoring of incoming
chinook has showed extensive use of inchannel emergency enhancement and high
Idegree of upstream passage at Woburn bridge.
Hannah Creek flows directly into Whatcom Creek and was the original spill point of the
' gasoline pipeline rupture. Fuel saturated bed and bank material within a 1000 foot
reach of the creek was excavated and disposed of. Inter-Fluve provided design and
construction oversight for the total reconstruction of the reach. The channel was rebuilt
j from the bedrock on up. Gravel and cobble were imported to first reconstruct the
channel grade. Pools and riffles were built into this the new channel. Large and small
woody debris were incorporated in the project to provide habitat for native trout while
providing bank stabilization and riparian terrestrial habitat near the stream. These
restorations involved close communication and coordination with a variety of federal,
state, city, tribal,private and corporate representatives in an active and changing
emergency,environment. Both Hanna and Whatcom Creeks are within Bellingham City
limits and required working within the constraints of an urbanized watershed.

Proposal for Engineering Design Services for Summer Lake Water Quality Project Tetra Tech,Inc.
' STATEMENT OF UNDERSTANDING
Consistent with the Fanno Creek Watershed Management Plan the City of Tigard has requested an
evaluation of the alternatives that will convert the existing Summer Lake to a free-flowing natural
stream channel during low flows. This feasibility also recommends increased shading of the water by x`
native vegetation to be planted along the shoreline. The concern is the increasing need to provide
' viable habitat for threatened species,Upper Willamette spring Chinook and winter steelhead. The r l 4
likely outcome is that by converting Summer Lake from an in-channel pond to a natural channel with
off-channel features, dissolved oxygen will be increased and stream temperatures will be reduced. In
addition the current outlet structure that results in the formation of Summer Lake is a fish passage
barrier that would be eliminated if Summer Lake is converted to a natural stream channel system.
' The goals of this feasibility study will be to provide a free-flowing stream channel with natural riparian
vegetation to provide shading and a diversity of habitat with minimal maintenance, remove fish
' barriers, improve water quality,provide an off-channel water feature for recreational benefits, and
comply with all regulatory requirements.
' APPROACH/SCHEDULE
To enhance the probability of project success, it is assumed that the Task Force includes resource
agency representatives (USA, ODFW, NMFS, etc.) who will provide input related to funding and
' regulatory requirements during this feasibility planning phase. We recommend monthly meetings of
the Task Force. It is further recommended that a pre-application meeting be conducted with the U.S.
Army Corps of Engineers,National Marine Fisheries Service, U.S. Fish &Wildlife Service, Oregon
Department of Fish &Wildlife, Oregon Department of Environmental Quality, and other permitting
agencies during this phase approximately at the time of selecting the preferred alternative. Feasibility
' planning without regulatory agency involvement throughout most of the process may lead to
significant delays during the permit application process. Additionally, the schedule proposed in this
scope is designed for this feasibility planning phase to be complete by early October, 2000 to coincide
' with City budget planning for fiscal year 2001.
TASK 1: DEVELOP EVALUATION CRITERIA
' In task 1, the project manager will attend a meeting with the Task Force and prepare a memorandum of
the meeting discussion with a statement of the objectives of the proposed project,regulatory
constraints/requirements, ecological functions and public opinions which will be used to evaluate the
' merits of potential alternatives for the project. Prior to the meeting, the consultant (with City of Tigard
project manager) will have prepared a "straw man" list of objectives and evaluation criteria to guide
discussion during the meeting. Consultant will identify evaluation criteria during the meeting to ensure
' the criteria reflect the consensus of the Task Force.
Product: Evaluation criteria developed with consensus of the Task Force.
Schedule: Four weeks total to review background materials, prepare meeting agenda and materials,
and schedule and attend Task Force meeting.
' TASK 2: CREATE ALTERNATIVES
The project manager and project engineers (with input from the City project manager) will develop
several (3-7) conceptual alternatives to accomplish the project objectives as determined in Task 1
(including off-line water feature). Alternatives will be verbally described and have up to 2 conceptual

Summer Lake Integrated Management Plan
Tigard,OR
City of Tigard
' The City of Tigard retained Tetra Tech in 1998 to investigate Summer Lake.Specific objectives of the project
were to evaluate turbidity,elevated water temperatures,nutrient loadings,aquatic plants,and animal/bird activity
that were believed to be impacting the appearance of the pond water.These factors were strongly interrelated and
the pond could be further adversely impacted by upstream development. Tetra Tech reviewed existing reports,
evaluated and determined the cost-effectiveness of various lake management alternatives,assembled draft and
final plans,and attended advisory committee meetings.The plan included evaluation of the following options:
' • Preventive measures such as reducing the duck population at the pond.
• Aquatic plant control-Chemical control with contact and systemic herbicides,Biological control
including the use of Grass Carp,Mechanical control including plant removal by dredging,hand removal,
and machines specifically designed for this purpose.
• Aeration with aerators,fountains and diffusers
• Chemical coagulation with aluminum sulfate
i • Develop a program to accomplish the purposes of the project including estimated costs of recommended
measures,(including ongoing operation and maintenance costs/requirements)plan of implementation,and
' required pen-nits.
Working closely with the City of Tigard and the Summer Lake Citizen Advisory Committee,a integrated lake
management approach was developed and included harvesting aquatic plants,applying lake bottom barriers,
providing vegetative shading,adding alum to control algae,and providing public education.
' Summer Creek Restoration Concept Plan Tigard,OR
City of Tigard,OR
Tetra Tech is currently working with the City of Tigard and the Unified Sewerage Agency to develop a concept
' plan for restoration of Summer Creek between S.W. 121"Avenue and the Summer Lake Dam.The goal of this
initial phase project is to develop a concept plan that is acceptable to the local neighborhood and permittable with
the reviewing agencies prior to proceeding with final design and construction.Agencies that were represented in
' an initial project meeting included Oregon Division of State Lands,Oregon Department of Fish and Wildlife,
Environmental Protection Agency,U.S.Army Corps of Engineers,and Oregon Department of Environmental
Quality.Agency concems are primarily related to increases in stream temperature and fish entrapment potential.
Established project objectives from that meeting included: 1)provide a flow-through meandering creek,2)provide
more shade than currently exists,3)provide large,woody debris,4)provide backwater areas that fill and drain,5)
mimic the meandering creek at two reference sites upstream and downstream of the proposed restoration reach,
and 6)low summer flows should remain in the channel.A concept plan has been developed that is currently under
review by the City of Tigard,USA and the neighborhood.Following resolution of any review comments,the plan
will be submitted to agencies for preliminary review and to seek concurrence with the concept plan.

' Seattle Dist*4 US Army Corps of Engineers
The Goldsborough Creek Restoration study was initiated to consider the removal of a deteriorated dam structure
along Goldsborough Creek which is a hindrance to fish passage.The restoration objective is to remove the dam
and to restore and stabilize Goldsborough Creek at a more natural gradient using a series of weirs that will allow
for unhindered upstream and downstream passage of resident and migratory fish. The design and engineering
' 5
Proposal for Engineering Design Services for Summer Lake Water Quality Project Tetra Tech,Inc.
' focused on the location,alignment,and sizing of 33 weir structures. Bank protection is also an important
component since the stream is confined and the peak flows typically last for a number of days. Combinations of
riprap,fabric-wrapped-reinforced-soil lifts,and vegetation were designed to withstand to expected flows within the
2000 foot long project reach.
' The objective of Tt's support for this project is to conduct necessary engineering,design,and construction support
services through project implementation to assist Seattle District in meeting"fast-track"scheduling goals of
project implementation in 2000. Three separate tasks have been identified as part of this contract: 1)preparation of
an Advance Planning Report,2)preparation of Plans and Specifications(P&S),and 3)provide Construction
Administration and Inspection services.
' Preparation of Advance Planning Report:This task involved additional engineering and design work beyond the
scope of the feasibility report that was required to establish the basis of design for completion of plans and
specifications.Under this task,Tt was responsible for the survey of additional cross sections and development of
' more refined topographic maps. Tt coordinated with and provided input to the Corps on geotechnical drilling
work and other required geotechnical studies. Based on new information,Tt performed additional hydraulic and
sediment transport analyses to verify and refine the concept design and also evaluated bioengineered methods for
' bank stability as an alternative to hardscape. Tt also provided analyses of mitigation for potential losses to flood
plain function,riparian areas,wetland impacts and any other potential impacts outside of the project footprint.
These efforts were closely coordinated with state&Federal agencies
' Pre aration of Plans and Specifications:Tt is under contract to developthe basis of design document contract
�
drawings,specifications and bid documents,construction cost estimate,and preliminary Operations and
Maintenance Manual for the complete dam removal,and stream restoration project.The final product will be
delivered as an Electronic Bid Package in which the drawings will be converted to the Computer Aided
Acquisition and Logistic Support(CALS)Group 4 raster format and the specifications will be converted to the
Adobe Acrobat Portable Data Format(PDF). Tt recently participated in an"over-the-shoulder"review conference
in which they met with the COE study team for a one-day workshop to go over 65%preliminary plans,outline
specs,and the preliminary cost estimate.Tt also completed necessary design documentation to obtain
' environmental permits for construction and to meet Corps of Engineers requirements.Tt has conducted field
reconnaissance and continues to coordinate with other project team members and stakeholders as needed.
Provide Construction Administration and Inspection Services:Tt is under contract to ensure that project
implementation is consistent with plans and specifications,that any required changes are fully coordinated
' between the construction contractor and the District,and to ensure all environmental requirements specified in
permits are complied with.Tt will provide construction administration and inspections service during the
construction phase of the project.
Matilija Dam Decommissioning,Ventura County,CA
' Los Angeles District US Army Corps of Engineers
Matilija Dam is located on Matilija Creek,a major tributary to the Ventura River,California. The dam was
constructed in 1946 for water supply and flood control,but has since filled in with sediment and no longer
' provides either purpose. Ventura County,the U.S.Bureau of Reclamation(USBR)and the Corps of Engineers
(Corps)are investigating removal of the dam to improve fish and wildlife habitat(particularly fish passage),restore
the natural sediment regime and enhance recreational opportunities. The Corps contracted with Tetra Tech,Inc.to
prepare preliminary plans and cost estimates for one alternative;removal of the dam and removal of sediment via a
' 6
Proposal for Engineering Design Services for Summer Lake Water Quality Project Tetra Tech,Inc.
'
slurry pipeline or conveyor,and also to evaluate the potential significant environmental impacts for several dam
removal alternatives identified by the USBR. Additionally,beneficial uses of the sediment were identified,
including beach nourishment and habitat purposes.
Task 1: Develop preliminary plan and cost estimates for sediment transport by slurry and conveyor methods,with
' the material being used as beach fill or to be temporarily stockpiled. Tetra Tech developed a preliminary
alignment for a slurry pipeline or conveyor from the dam site to the beach or other disposal site and developed
costs and schedule for this dam removal alternative.
Task 2: Identify the significant environmental impacts of the alternatives identified by USBR. Tetra Tech
' evaluated the potential significant environmental impacts of each alternative in a format that can be readily
converted into an Environmental Assessment(EA)or Environmental Impact Statement(EIS)during feasibility.
' Significant impacts were primarily related to sediment transport and water quality impacts during and following
dam removal,in the river and at the potential disposal sites.
Task 3: Identify beneficial uses of the sediment. Tetra Tech identified several beneficial uses of the sediment
' which will be evaluated further in feasibility: beach nourishment,commercial uses,spawning gravels and as
topsoil for revegetation projects.
Task 4: Preparation of appraisal report supplement. Tetra Tech prepared draft and final appraisal report
' supplements with Tasks 1-3 described in detail.
' Watershed Planning and TMDL Compliance Activities in Aliso/San Diego Creek Watersheds
County of Orange,Public Facilities and Resources Department
Tetra Tech was contracted by the County of Orange to provide technical assistance on the water quality planning
and water quality initiatives being conducted in the Aliso Creek and Newport Bay/San Diego Creek Watersheds.
This project has an emphasis on understanding water quality problems and recommending approaches for
' alleviating the impairments to beneficial uses in these watersheds.The work performed by Tetra Tech will be
closely integrated with the watershed feasibility studies being conducted in these watersheds by other agencies.
The goal of the project is to assist Orange County in their compliance efforts for Total Maximum Daily Load
' (TMDQ allocations for sediments,nutrients,bacteria,temperature and toxicity.
Tetra Tech conducted an aquatic life assessment for Aliso Creek,which included habitat characterization and
mapping, and evaluation of natural community structure and diversity within the channel. Assessment was
' conducted using established bioassessment techniques such as the U.S. EPA and Water Environment
Federation bioassessment protocols for use in streams and rivers.
' Tetra Tech also assessed the nutrient and sediment loads in the lower San Diego Creek watershed.The project
further assessed the biological resources existing in the project area and identified opportunities for and constraints
on implementing sediment reduction water quality improvements,fish and wildlife habitat restoration and
' recreational enhancement.Our assessment identified that ten vegetation community types and three aquatic habitat
types occurred in the study area.The entire study area is surrounded by developed/urban areas(except upstream of
' the San Joaquin and Sand Canyon Reservoirs). Tetra Tech advised that the riparian corridors provided the best
opportunity to restore and enhance wildlife corridors and restore native plant communities. Additionally,some
sediment control and water quality improvements may occur as a secondary benefit of restoring riparian habitat.
' Tetra Tech is currently preparing conceptual designs for several enhancement projects.

' PROJECT EXPERIENCE
San Diego Creek Watershed Analysis, Orange County, CA. (March 2000). Ms Martz conducted a
' review of the biological resources in the study area and field verified the vegetation communities and
fish and wildlife distribution. She wrote a report documenting the biological resources and provided
updated GIS layers of the vegetation and stream conditions. She identified the opportunities and
' constraints associated with the implementation of biological, recreational, water quality and sediment
control enhancement projects in the study area. She developed conceptual designs for projects and
identified opportunities to reduce habitat fragmentation.

' Green-Duwamish Basin and Stilliguamish River Ecosystem Restoration Studies (ongoing). Ms.
Martz is currently preparing feasibility reports for these two ecosystem restoration studies for the
Seattle District, Corps of Engineers. Responsibilities include the review of all existing reports and
study documentation applicable to the study area for incorporation into the feasibility report;
development of report contents and text to ensure that all regulatory requirements are satisfied;
' environmental technical review of habitat restoration designs for over 60 project sites.
Matilija Dam Decommissioning, Matilija Creek, Ventura County for Los Angeles District Corps
' of Engineers (Feb-March 2000). Ms. Martz evaluated the potential environmental impacts from four
dam removal alternatives proposed by the Bureau of Reclamation based on existing literature. She
wrote a reconnaissance level report, which will become the basis for the Corps and Bureau of
' Reclamation appraisal reports, with recommendations for further studies needed during feasibility.
Porter Levee Section 1135 Habitat Restoration. Ms. Martz was the project manager and one of the
' construction supervisors for this habitat restoration project on the Green River, King County, WA. She
managed all aspects of planning and design for this expedited project. All phases of this project were
completed in 1999. This project involved the breaching of a levee to reconnect an ox-bow to the Green
' River. Additional wetland habitat was created and the floodplain was revegetated with native species.
She designed the revegetation and monitoring plan for this project.
' Sammamish Weir Section 1135 Habitat Restoration. Ms. Martz was the project manager, lead
biologist and one of the construction supervisors for this habitat restoration project on the Sammamish
River, King County, WA. She managed all aspects of planning and design for this expedited project.
Planning, design and construction were completed in 1998. This project involved the replacement of a
weir with a new weir designed to facilitate fish passage at low flows and bank stabilization and
' revegetation of the riparian zone. She designed the monitoring plan for this project, and conducted the
first year of monitoring.
' Bear Creek Section 1135 Habitat Restoration. Ms. Martz was the lead biologist for this project
from 1996-2000. She initially started the study with the City of Redmond and King County. She
provided design input and completed all environmental documentation (permit applications, ESA
compliance, etc.) during the feasibility phase, and assisted with design during the plans and
specifications phase. This project involved the creation of a new meandered creek channel to replace
the existing straight heavily armored channel. The primary goal of this project is to create winter
' rearing and refuge habitat for juvenile salmon and reconnect the creek to its floodplain.
Cedar River Section 205 Flood Control Project. Ms. Martz was the environmental coordinator for
' this flood control project in and along the lower Cedar River, Renton, WA. She designed and
conducted 4 years of environmental baseline monitoring of stream habitat, fish use (salmon, longfin
smelt, resident trout), invertebrate populations and riparian vegetation in the project area. She was the
' primary author of the NEPA Environmental Impact Statement (EIS). She provided design input,
developed a mitigation and monitoring plan and obtained all necessary permits during the plans and
specifications phase. She supervised construction of the mitigation sites and monitored them for one
' year following construction.

FRIENDS OF SUMMER LAKE COMMENTS
• ON
DRAFT ALTERNATIVES EVALUATION CRITERIA
The Task Force voted to accept the April 27, 2000 Technical Memorandum submitted by
Fishman Environmental Services as satisfying the objectives of Phase I of the project.
Friends of Summer Lake voted in the negative because we did not agree. The project is
now reaching the point where it is time to revisit why the Task Force voted to undertake
Phase I. Phase II consultants (Inter-Fluve Assoc.) need to be aware of what has
transpired so that evaluation criteria and alternatives are looked at in relation to prior
understandings and developments within the Task Force.
Phase I, as approved by the Task Force, was to have qualified consultants "examine and
report whether there is an economically and ecologically viable way to improve water
quality in the waters of Summer Creek above Summer Lake (with a cost estimate of
doing so)to insure that those waters will provide year-round habitat for winter steelhead
and spring Chinook salmon. Phase I is to cover consideration of all waters above
Summer Lake dam."
Phase II provided for execution of"the work contained in the current Request for
Proposal or as amended by the City in response to Task Force recommendations" and
further, "whether Phase II is carried out depends on the conclusions reached by the
• consultants in Phase I." Phase II is essentially that work described in the Request for
Proposal for the Summer Lake Water Quality Project.
Phase I was concluded by the acceptance of the Fishman report by the Task Force with
the understanding by Mr. McAdams and Mr. Halberg (the proponent and second of the
motion to approve the Fishman report), and perhaps others,that Phase II would
ultimately provide full answers to the questions posed in Phase I. Certainly the Task
Force members knew at the time that the Fishman report was based on an April 19th
cursory examination of conditions in Summer'-Creek. The first sentence of the Fishman
report alludes to being asked by USA to prepare a"brief analysis." That is all they were
able to do given the time and resources allotted them by the City and USA. Fishman
certainly did not fully deal with all of the issues raised in Phase I. There were simply not
able to fully investigate the questions and issues raised in Exhibit A(Scope of Work and
Special Terms and Conditions) attached to their report. So Friends of Summer Lake
believe that Phase II must attempt to address, in full detail, the issues and questions raised
in Phase I that got no more than a"brief analysis."
We believe the key questions that were asked of consultants in Phase I (Exhibit A) are
being ignored in the draft Mission Statement. Those questions are the following:
(1) "If the conditions above the Lake do not meet standards (water quality
and fish passage), are there actions that could be taken to bring the reach into
compliance?"
• (2) "What are the range of costs associated with the needed activities?"
1
• As to question 1, Fishman could not quickly provide a definitive answer but among other
things said: "Separation of Summer Lake from Summer Creek and removal or
partially breaching of the dam are the most ambitious and likely most expensive of
the alternatives. They went on to say that those actions seemed to be worth
consideration"particularly if the less expensive options such as flow augmentation
and enhancement,tree and shrub planting are found to be reasonably effective and
further compliance measures are warranted." They further stated in relation to
measuring the effectiveness of a flow augmentation and infiltration alternative,that
"a series of temperature monitors strategically place in the three forks of Summer
Creek will provide a good indication of whether this alternative alone will be
adequate to meet the temperature goals. If the data show that acceptable
temperatures of 64° F are unattainable upstream of the lake, it makes little sense to
remove the dam and provide passage for salmonids." Fishman also said, with respect
to removing phosphorus through detention facilities, they may conflict with other
desirable goals such as reduction of stream temperatures or improved fish passage."
It is, of course, easy to observe that Summer Lake dam works as a heat sump keeping
most warm waters from moving downstream when, during hot weather, the flow over the
dam is small or nonexistent. The dam seems to protect resident cutthroat trout in
downstream Summer Creek from over-warm water while acting as a sink for nutrients,
helping attainment of phosphorus standards downstream.
• Regarding question 2, Fishman opined that moving Summer Lake offline and partial
breaching of the dam were the most expensive ways to try to meet standards and
removal of instream detention facilities (other than Summer Lake Dam) along with
shading with trees and shrubs were the least expensive.
Having provided a background for our comments on the Alternatives Evaluation Criteria
Draft (AEC Draft), it seems all too clear that the "Mission Statement" set forth in the
Draft misses the important points entirely. The "biological integrity" of Summer Creek
above the lake has already been severely compromised by urbanization. Will removal of
the dam and planting trees assure enhancement of the integrity of upper Summer Creek in
a significant degree? That is the real question. Just what the mission statement means is
subject to all kinds of interpretation. That suggests it is essentially meaningless. It
doesn't move the Task Force any closer to determining whether the target temperature
range (64°F) or phosphorus standard can be met. It seems not have a focus at all,
allowing those in charge of the project to do anything, as long as their efforts can in
some, even slight, manner appear to "enhance the biological integrity of Summer Creek."
Reading as if no one has read the Fishman report or the available data from water quality
sampling in Summer Creek,the AEC Draft suggests that "the project must improve lake
and downstream water quality" without considering that making that happen must take
into account the fact that waters flowing into the lake are responsible for much of the
poor quality in the lake and the lower reaches of Summer Creek.
•

iWe suggest making the Mission Statement read something like the following: "Assess
what can be done economically and environmentally upstream of the lake to improve
water quality throughout Summer Creek so that it can be year-round rearing habitat for
cutthroat trout and the threatened salmonids." The Fishman report, indefinite as it is,
does at least address this and other important questions the Task Force must address and
it suggests what some of the potential conflicts will need to be resolved as this project
goes forward.
There seems to be an importance ranking intended in the words chosen to follow the
word"Project."For example: "Project must".... The "must"word suggests that it is a
ranking word, rising higher in importance than"allows," "encourages," "enhances,"
"creates," etc. We observe, for example, under Water Quality that"lake and
downstream water quality" and visual aesthetics "must" improve. How are these
imperatives to be measured and understood? Are they to be absolutes or to be glossed
over as laudable goals—the attainment of which actually may be never measured? Will
they actually play a significant role in meeting the standards for temperature, bacteria,
dissolved oxygen, nutrients, pH and chlorophyll in Summer Creek? Exactly such
questions are matters now in litigation between plaintiff Tualatin Riverkeepers who
argue those standards must be attained in the Tualatin River, and by logical extension in
Summer Creek, while defendants the federal Environmental Protection Agency and its
cohorts—Oregon DEQ and Unified Sewerage Agency—protest that they are doing all
they can, given physical limitations over which they have little control. One of those
• limits is the fact that natural phosphorus levels in Tualatin River Basin soils average more
than twice the national average. That is a limitation that the public agencies seem not be
able to completely overcome. None have the physical capacity or political clout to force
its effect to be mitigated to the extent that existing phosphorus standards are certain to be
met or to stop urbanization that is responsible for mobilizing the phosphorus.
We believe that whatever evaluation criteria are finally approved, they ought to focus on
two or three important scientifically and economically attainable objectives that can be
monitored for effectiveness. The focus should be on mutually supporting objectives, with
identification clearly made as to those that are mutually exclusive and cannot be attained
without unacceptable tradeoffs in environmental and economic terms.
We also note that one of our suggested criteria has not been explicitly listed and would
like to know why. It would state something like this: Project must protect the public
interest; i.e.,there will be high public acceptance because the measures taken will be
known and understood to provide net public benefit. Perhaps this is meant to be implict
in the first Other statement, but if so, it is not clear that having neighbors working
"collectively on a solution'with the City and Agencies will assure that the public interest
is adequately protected.
