Preface
This recommended action plan outlines a suggested role and
strategy for the Clackamas River Basin Council in protecting and restoring the
health and integrity of Rock and Richardson watersheds. This strategy is based
on information in the October 2000 Rock and Richardson Creek Watershed
Assessment. It is also based on the assumption that significant changes in land
use through the urbanization and associated development of major portions of
these two watersheds is inevitable.
This is a recommended action plan, and has not been adopted in whole or in part by the Clackamas River Basin Council.
Recommended Action Plan
1. Background
The assumed goal for the Clackamas River Basin Council is to
protect and restore the integrity of Rock and Richardson watersheds within the
context of work that must be done for the entire Clackamas Basin. The Council
has identified four primary goals and priorities for their work in the larger
Clackamas Basin.
- Maintain and improve native anadromous and resident fish habitat in the Clackamas River basin.
- Maintain and enhance water quality of the Clackamas River to meet and surpass the state water quality standards.
- Maintain sufficient flows to support in-stream beneficial uses.
- Protect and enhance natural areas associated with river and stream habitat.
Since the financial, labor and political resources of the Council
are limited, setting priorities for action is crucial. In the Rock and
Richardson Creek watersheds these priorities must be driven by the fact that
pending urbanization will have an overwhelming influence on these two
watersheds in the near and long-term. Actions such as upstream riparian tree
planting and bank stabilization — which can have significant value in rural
watersheds where land use patterns are relatively stable — may be relatively
inconsequential in comparison to the need to address the potential impacts of
urbanization in the core of these watersheds. In the face of pending
alterations to the landscape, Council efforts should be focused first on
protecting the best fisheries habitat and watershed values, second on ensuring
that watershed health is maintained as urbanization occurs, and finally on
restoring and rebuilding more damaged ecosystems.
The intent of this recommended action plan is not to provide an
exhaustive list of all potential data collection, restoration, education and
community building projects. Rather, it is intended to outline a strategic
approach for the Council to protect and enhance ecosystem health in these two
watersheds, and is presented here in five sections.
The activities within this recommended approach provide multiple
opportunities for integration of Council efforts in education and outreach,
monitoring, research, planning and policy development, and on-the-ground
actions. There are countless other actions that the Council could take towards
watershed health, but these are suggested as the most strategic.Ý
2. Protection and Restoration of Key Areas
The watershed assessment (Ecotrust, October 2000) identified
three critical areas for salmonids in Rock and Richardson Creeks: Lower Rock
Creek, from the mouth up to the falls; Middle Rock Creek, from SE 172nd
east to Foster Road; and the forested canyons of Lower Richardson Creek. If
salmonids cannot be retained in these core sections, then they cannot continue
to exist in the respective watersheds. Moreover, these core salmonid areas and
the broader zones that support them also have significant water quality, water
quantity, soil stability, and wildlife habitat values. If the Council can do
nothing else in these two watersheds, it should work to ensure that existing
values in these areas are retained and enhanced through protection, monitoring
and restoration.
The recommended protection of these core areas does not negate
the value of protecting and restoring other important ecological values in
these two watersheds. For example, the riparian zones on all creeks in these
two watersheds are critical habitat vital to the survival of salmonids. Good
water quality and healthy riparian zones are the key to salmonid survival. The
Council should make every effort through policy and private landowner incentives
to afford maximum possible protection to these riparian areas.
2.1 Forested Riparian Zone of Lower Richardson Creek
The mostly intact, forested canyon of lower Richardson Creek
(reach 1) is fundamental to the health of this watershed and to the presence of
salmon is this creek. This particular area also provides wildlife habitat
connectivity between the upper Buttes area and the forested areas of the
Clackamas Valley. This zone has been roughly delineated on the accompanying
Opportunity map based on the extent of steep slopes, soils with high erosion
potential, wetlands, and intact forest cover and other natural areas. Highly
erodable soils cover 40 percent of this 620-acre area, over one quarter of the
area has slopes greater than 25 percent, and wetlands cover a little over three
percent, or nearly 20 acres. Over 80 percent of this zone is forested,
primarily in closed canopy mixed conifer deciduous forest.

The protection of this canyon area and the critical salmonid
habitat it supports is particularly important as parts of this watershed
continue to urbanize. Most of this canyon zone lies outside the urban reserve
zone and is therefore unlikely to be developed in the near future. Rather, the
principal threat to the water quality, water quantity, soil stability, and
wildlife habitat values provided by this area is from timber harvesting by
current or future landowners. Given the fragile nature of much of this zone and
its direct connection to critical salmonid habitat; tree removal and other
activities associated with timber harvesting in this particular zone could have
a significant impact on overall watershed health. Current State of Oregon
forest practice regulations do not prevent the removal of most of this forest
cover. The Council must take a lead role in ensuring that this area remains
largely intact. This will require working with landowners, the Metro
Greenspaces Program, Clackamas County, and local land trusts to find
appropriate economic and policy mechanisms for retaining this area as intact
forest.
This lower canyon zone includes about 191 separate tax lots owned
by 142 different landowners. The average lot size is about six acres, although
sizes range from a little over one thousand square feet to 43 acres. Many of
the larger lots, however, extend well beyond the delineated zone. Most of these
tax lots are occupied; about 70 percent have assessed improvement values of
$25,000 or more.
2.2 Forested Riparian Zone of Lower Rock Creek
As in lower Richardson Creek, the forested riparian zone of lower
Rock Creek (reaches 1, 2 and 3) is fundamental to the health of that watershed
and to the hope of restoring healthy populations of salmon to the lower end of
this creek. This zone is also delineated on the accompanying Opportunity map
based on the extent of steep slopes, soils with high erosion potential,
wetlands, and intact forest cover. Highly erodable soils cover 30 percent of
this 293-acre area, and nearly 40 percent of the area has slopes greater than
25 percent. Over 65 percent is forested, primarily in closed canopy mixed
conifer and deciduous forest and nearly 18 percent is in agriculture.

Like the Lower Richardson canyon area, protection of the Lower
Rock Creek canyon area and the critical salmonid habitat it supports is
particularly important as parts of this watershed urbanize. All of this zone
lies either within the current urban growth boundary or within the urban
reserve zone and is therefore likely to be developed in the near future. Given
the fragile nature of much of this zone and its direct connection to critical
salmonid habitat, intensive development could have a significant impact on
overall watershed health. The Council must take a lead role in ensuring that
the remaining forest cover area remains largely undisturbed. This will require
working with landowners, the Metro Greenspaces Program, Clackamas County, and
local land trusts to find appropriate economic and policy mechanisms for
retaining this area as intact forest.
The lower Rock Creek canyon zone includes about 229 separate tax
lots owned by 161 different landowners. The average lot size is about 2 acres,
although sizes range from a little over one thousand square feet to 50 acres.
Many of the larger lots extend beyond the delineated zone. Most of these tax
lots are occupied; nearly 60 percent have assessed improvement values of
$25,000 or more.
The Council must take a lead role in ensuring that this area
remains largely intact. This will require working with landowners, the Metro
Greenspaces Program, Clackamas County, and local land trusts to find
appropriate economic and policy mechanisms for retaining this area as intact
forest.
2.3 Middle Rock Creek
The Council should take a lead role in restoring the riparian
zone and stream channel in middle Rock Creek (all of reach 5 and parts of reach
4 and 6). Part of this area contains a small and isolated population of
cutthroat trout in a stretch of Rock Creek between Foster Road and SE 172nd
Avenues. Generally there is poor riparian cover in this section, partly
channelized stream sections, a lack of habitat complexity and a lack of refuge
habitat. The stability and recovery of cutthroat trout in upper Rock Creek
depends on restoration of riparian cover and habitat in this zone.
As roughly delineated on the Opportunity map, this area is about
300 acres in size, and is characterized by primarily gentle slopes, although
eleven percent of the area has slopes of between 25 and 50 percent. Currently,
only 62 percent of the land cover is forested. Tree planting and restoration is
most important for areas closest to the creek.

The middle Rock Creek zone includes about 189 separate tax lots
owned by 137 different landowners. The average lot size is about four acres,
although sizes range from a little less than 700 square feet to 125 acres. Many
of the larger lots, however, extend well beyond the delineated zone. Most of
these tax lots are occupied; about 65 percent have assessed improvement values
of $25,000 or more
The Council will need to work with landowners and residents of
this area to:
and address them with best management practices, and
riparian zone.

3. Community Outreach and Education
Community outreach and education should be aimed at creating
awareness of the role of watersheds and key watershed issues, building support
for community watershed efforts, and changing behavior patterns in ways that
restore and enhance watershed health. Many of the activities of the Clackamas
Basin Council provide important outreach and education opportunities.
Activities that protect and restore these creeks should be used as a vehicle
for larger Clackamas Basin protection efforts. Moreover, there will be a lot of
media publicity as this area urbanizes, and the Council should be prepared to
use it to advantage There are at least two specific projects, however, for
which education is the principal goal. In conducting outreach and education the
Council should stimulate community partnerships with local schools, landowners,
and businesses, and aim to create a watershed community that will take the
individual steps needed to maintain and restore watershed health. Two excellent
avenues for reaching the local community are the Damascus and Sunnyside
Community Fairs in July and August as well as the Rock Creek Community
Association.
3.1 Damascus Restoration Demonstration
The Council should take a lead role in restoration of the section
of Richardson Creek that has been damaged by channelization and the failure of
the Safeway and Dairy Queen septic systems. This site is a critical link to
water quality in Richardson Creek. Moreover, while it may not be the most
important restoration project in the watershed, it is the most visible one and
provides an excellent opportunity to connect residents to the Richardson Creek
watershed and demonstrate the potential for restoration. As a leader in this
effort the Council will need to work closely with the landowners, broker the
roles of various local and regional agencies, search for creative solutions to
the specific challenges of the site, and gather and focus the energies of local
residents. For example, while the Damascus waste treatment issue has often been
framed as a dilemma between inadequate septic and unavailable sewer systems
there may be other viable alternatives for onsite biological waste treatment. A
Living Machine is one example of an effective and economical system for
biological treatment of high strength industrial wastewater and sewage that
could offer an effective solution. Living Machines incorporate and accelerate
the processes nature uses to purify water. With the help of sunlight and a
managed environment, a diversity of organisms including bacteria, plants,
snails, and fish break down and digest organic pollutants. Depending on the
climate, Living Machines can be housed in a protective greenhouse, under light shelter
or in the open air.
The Council may be able to play a pivotal role in brokering
resources and partners to implement such a local solution.

3.2 Use of Fertilizers, Herbicides, and Pesticides
The Council should take a lead role in educating residents,
operators, businesses and vendors about the role of fertilizer, herbicide and
pesticide on water quality and watershed health, and more sustainable
alternatives to their use. This outreach and education effort should be
strategically focused for greatest long-term impact. Likely partners to the
Council may include University Extension and Metro as well as local business
associations and non-profits.
Conventional agriculture relies on massive application of
pesticides, fertilizers, and fossil fuels, which result in soil erosion and the
contamination of groundwater and ecosystems. As an alternative, sustainable
agriculture eliminates the use of pesticides and artificial chemicals and
largely maintains soil fertility by application of on-farm residues and
rotation of nitrogen-fixing crops. Any external fertilizers must themselves be
sustainably produced. Soil erosion is minimized through crop choices,
cover-cropping, and low-till methods, and crop diversity provides inherent
resilience in the face of pests, disease, and weather extremes.
Most, but not all, aspects of Sustainable Agriculture are addressed by organic
certification standards like those administered state-wide by California Tilth
and Oregon Tilth and nationally by the U.S.D.A. This form of product labeling
and certification is well-understood in the marketplace, and can attract a
premium of 50% or more. The organic food market is the fastest growing sector
of the food industry, with a growth rate of 20% per year over the last two
decades. Processors, handlers, marketers, and restaurants can also receive
organic certification, creating a wide range of opportunities for value-added
production.
Agriculture is only one source of fertilizers, herbicides and
pesticides, and a diminishing one in the Rock and Richardson Creek watersheds.
The use and impact of fertilizers, herbicides and pesticides on watershed
health in urban and suburban areas can often exceeds that of agricultural areas
due to the unregulated use by untrained homeowners. Owners of farms and
household landscapes and gardens can improve watershed health by maintaining
their own soil fertility, avoiding pesticide use, and preventing erosion.
