Context Overview
he City of Lake Oswego initiated the master planning
process for George Rogers Park as the list of proposed
improvements to the park became quite lengthy and
unwieldy. A consultant team of landscape architects. historians,
natural resource scientists. architects. and transportation
engineers was engaged to facilitate a public master planning
process for George Rogers Park with the final product to be a
narrative plan for phased improvements and implementation
recommendations. To best understand the park and its context,
the consultant team led investigations to assess the park site's
history, its features and structures, its natural resources, and
transportation influences. This document is the summate• of
those investigations.
A series of focus group meetings accompanied the invesl.iga-
tions, examining the social context of the park at a regional
level, in the community. in the neighborhood, and with special
interestgroups that use the park. These meetings and the
public involvement process used to develop the master plan
recommendations are summarized in the Plarf Uri elopmenl
document of the George Rogers Park .11aster Plan.

unclear whether the Clowewalla of the West Linn area had
villages farther north along the \\,est bank ofthe Willamette
River. There is no documentary evidence of a \-illage at the
mouth of'Os%%-ego Creek in the earls historic period, but the
absence of such a settlennent may be the consequence of the

The treaty ceded to the United States the entire Willamette
Valley, extending from the summit of the Cowst Range to the
summit of the Cascada Mountains then north to the Columbia
River and down the middle of it from the Cascade Falls to Oak
Point. The cession embraced the entire watershed of the
Clackamas River and both banks of the Willamette to the river's
mouth. The agreement • secured at. Dayton, Oregon• was pre-
lude to the removal ofthe Clackamas and other Indians of, the
Willamette Valley to the Grand Ronde Reservation (Kappler

The smelter produced its first "pigs" on August. 24, 1867. The
ore came from deposits on the south side of Sucker Creek about
1.5 miles from the Willamette River. Limestone, used in the
smelting, was imported from the San Juan Islands; sand, used
in processing, came from the Sandy River delta. The iron found
uses: in 1868 the plant produced cast iron water pipe for use in
Portland and. in March. a cast iron stove installed at the Ladd
r and Tilton Bank (Goodall 1958:45).
The Oregon Iron Company then fell oil hard times. Disputes
arose about water rights: allegedly this conflictforced the
closing of the plant in 1869 (Goodall 1958:46). In 1870 Oswego
was again an ordinary, little community of 146 residents on the
west bank of the Willamette. Its primary distinction was a
rambling. deserted iron mill.

On March 17. 1945, the Oregon Iron and Steel Company sold
for $13.234.60 to the City of Lake Oswego, the eastern portion
of what was to become George Rogers Park. The land included
the site of the former Oregon Iron Company facilities. Paul F.
Murphy, vice-president, and William C. Foster, secretary, were

conveyed subjected to easements, roads. state holdings to the
high water mark (on the navigable Willamette River), and a
state wild bird and game refuge agreement (Anonymous n.d.a:

In 1919 the Lake Oswego Garden Club began landscaping in
the park. The work included leveling the grade and laying out
paths and plantings. In 1951 the volunteers set out red roses,

Lake Oswego along the section of land that separates
Oswego Lake from the Willamette River. As illus-
trated in Figure 1. State Street borders the park to the wast
and south, Ladd Street to the north, and the Willamette River
to the east. A portion of they park extends west underneath the
bridge of State Street and is accessed via recreational trails
along Oswego Creek.

Lake Corporation Dam and Powerhouse
The western houndary of George Rogers Park is defined by
State Street and the Lake Oswego Dam. The park extends In a
linear fashion beneath the brldge of' Highway 13 (South State
Street) along Oswego l'rcek to the foot ol'the dam below the
1
bridge of McVey Street. The Lake Corporation uses the dam to
regulate the water level of Lake Oswego, with excess water
funneled off in a "penstock" or wooden slat pipe that runs first
to a surge tank building. located at the corner of State Street
and Green Street and then to a powerhouse concrete building
located further in the park, to the north of Oswego Creek and
below Green Street. The surge tank structure administers the
flow of water to the powerhouse. and reduces the effects of
water hanuner in the penstock pipe. An overflow spillway from
the surge tank drams to Oswego Creek.
The powerhouse generates hydroelectric power from the dam's
water spill during winter months when water is abundant from
rains. In the sununer. the powerhouse is idle,

George Rogers Park occupies a site. which is widely variable in
(.erns of terrain. The park is comprised of a series of hillside
terraces and steep slopes tliat step down towards Oswego Creek
to the south and the Willaniette River to the east. A nulnher of
the terraces on the site are underlain with bedrock. creating
precipitous slopes between the terraces. the stream and the

Goi-ge Rogers Park is located on the west bank of the
\\ allamette River. and includes the mouth of Oswego
Creek. below the Lake Oswego dam, as well as bluffs to
the nl)rt h and south of the creek (Township `L South, Range 1
East., Sections 10 and 11). The park location is shown in
Figure 5.
The Park provides the visitor the opportunity to experience a
variety of habitats, ranging from mature upland conifer stands
dominated by Douglas Fir: younger mixed stands of Bigleaf
Maple, Western Red Cedar, and fir: bottomland riparian stands
of Red Alder, Oregon Ash, and willows, emergent wetlands and
open water, and landscaped gardens and open spaces. The

Geology, Soils and Hydrology
Geology
The geology of the Lake t)s 1 Ko arca previous to 15 million
year,, ago is largely unrecorded. although a pile (possibly all
oceanic Mandl of Focene volcanics and sediments approxi-
mately -10 million years old is exposed further north in Tryon
Creek State Park and Elk Rock Park. The major rock features
exposed within George Rogers Park are flows of the Columbia
River basalts. The oldest flows are the Sentinel Bluffs unit
exposed along the Willamette River just north of' the Oswego
Creak confluence. An argon date for these flows places them at
approximately 15.6 million years ago. On top of t hese and
forming most of the bedrock within the park are two (,inkgo
flows, which lie on top of a thin sedimentary unit on top of the
Sentinel Bluffs. On the hillside to the south In the portion of the
park along the Willamette River are exposed flows of the Sand
Hollow unit. These are elated at 15.3 million years.
The park hes an t he spial' Lone of a series of fault I rending
along the axis of'( )swego Lake and a series of fault trending
along the wosi hills. The area of the park has probable small

Soils
The scouring of late Pleistocene and perhaps later floods from
Lake Oswego into the Willamette River has left the immediate
park area largely bereft of older soils. Soils within t ho park are
mapped as xerochrepts and haploxerolls (Figure To very steep
in the lower portion of the park. The upper portion of ().swego
Creek near the lake dam is mapped as xerochrepts-rock out-
crops. moderately steep. An area of Willamette River sediments
north of the Oswego Creek outletis mapped as McBee silty clay
loam (cumulic ultic haploxeroll). Slag deposits from the 1911'
century iron smelting form the north bank of'Oswet;o Creek in
the vicinity of the footbridge.
Hydrology
The hydrology of Oswego Creek has been quite dependent on
human engineering throughout recent historical tine The
opening of the Oswego Canal at the west end of i he Eike in 1873
probably increased flood flows through Oswego t'rei 1, until the
Oswego Dam was constructed in 1921. The const rnct con of t he
present dam with its major outfall through a wooden tripe east
of State Streetprobably considerably reduced flow; t hrough the
upper portion of the channel. Gauging data from Oswego Creek
at it location near the dam between May 8. 1958 and September
11, 1958 show maximi► discharges of 7.5 cubic feet per second
(cfs) and minimum discharges of 1 cfs through this period. The
flows through Oswego Canol fin• the same period have a maxi-
mum flow of'approx►mately 112 cfs and minimum flows of 12

Upland Coniferous Forest (A)
The upland coniferous forest community is dominated by
Douglas Fir (Pseudotsuga rnen,lr.ih. with minor constituents of
'
Bigleaf Maple (Acer nracroj)hOhim). Grand Fir (Abies grandis).
Western Red Cedar (Thuja phralo). and others. This commu-
nit), is most evident on the southern slopes above Oswego
Creek, primarily upslope of the main trail. Douglas Fir on these
slopes range from less than 12 inches diameter at breast height
(dbh) up to at least 30 inches dbh: some of the trees arc, likely to
be over 65 years old. The current structure probably results
from limited disturbance (i.e. logging activity) for several
'
decades at least, which has allowed the Douglas Fir to overtop
any deciduous trees and dominate the stand

Riparian/Wetland (D)
The riparian wetland community is a narrow fringe along the
lower reaches of Oswego Creek, where backwaters from the
Willamette River and high flows from the Creek combine: to
limit most woody vegetation. This community grades to deep
water habitat unable to support rooted vegetation.
With the exception of occasional hydrophytic woody species (i.e.
Pacific Willow and spiraea), this community primarily supports
stands of Reed Canarygrass. Other species present include
Purple Loosest rife (Lyth ruin salicar•ia) and Yellow Iris (Iris
pseu(lacorus), both non -natives. Purple Loosest.rife and Reed
Canarygrass are considered nuisance plants by the City.

Wildlife Habitat
The location of George Rogers Park creates some unique oppor-
tunities for viewing wildlife species. especially those that are
associated with aquatic habit;it � Almost any species using the
Willamette River as a travel n)i ridor could be seen at George
Rogers Park. The backwater area formed by Oswego Creek at
Its confluence with 1110 W111anuetw l i .'r provides a calm water
resting place for a varicly of « Illllllc• sl ccws. and a small beach
located along the Willamel le Niver is a popular resting place for
various species of waterfowl and wading birds, such as Canada
geese (Branla canwlcn,. I;) Mallards (:liar pkr/vrhiru.ch.os),
cormorants. (Phalacrocorrr.r cnn•iltr.$), and greal blue herons

Beyond (lie aquatic habitats. the use of George Rogers Park by
wildlife is most likely limited to birds and small mammals. The

tures. Few large snags are found in the park and downed logs if,
present., are covered by English Ivy, The shrub component is
'
very limited and English Ivy dominates the herbaceous layer.
The English Ivy hurts the health of the park in other ways.
Downed logs and rock outcroppings used as foraging and
'
denning sites by various species of wildlife are rendered inacces-
siblc by the thick blanket of ivy.
The usefulness of George Rogers Park to wildlife is lnuitc(1 by
its location in the landscape. An important aspect of wildlife
habitat is the connectivity of one area of habitat with another
,
Developed neighborhoods surround the park on I hree sides and
the Willamette River on the fourth. Species that travel through
aquatic habitats can come and go from the Park with relative
'
case. however more terrestrial species access and moven(ent are
limited by roads and developed areas. Therefore the doniinanl

this section of the creek was obtained using a topographic map
marked with 1 foot isoclines. The contour neap did not cover the
entire site area. Coverage ended approxinlatelY 120 feet up-
stream of the road overpass. The habitat assessment was
qualitative. Instream habitat and riparian vegetation was
evaluated with an emphasis on pot'ent'ial fish habitat. Addi-
tional historical fishery information was solicited from Oregon
Department of Fisheries and Wildlife biologists.
Riparian Zone
The creek sits in a steep sloped. constrained valley dominated
by bedrock. Large blocks of rock that have fractured from t he
bedrock of adjacent slopes have slid down into the stream in
several places. The slopes leading clown to Itie creek are pre-
domllrrntly vegetated with an over:st.on, of Douglas fir, particu-
larly upslope of the foottrail on the south side of the creek.
Doww,lope of the trail. a mixture of hardwoods including
cottonwood alder, ash, willow and maple is found. IIII nedlately
adjacent to the stream the most common plant is willow The
stream generally had an open overstorY canopy along its length.

Anecdotal fish information was provided by Jim (_rimes and
Greg Rohart (0DF1Y fish biologists). Each suggested that

capacity for juvenile salmonids. Flows are probable ext renlely '
limited during the summer. Flow data from Oswego t'reek
taken just downstream of the dam identifies flows ranging from
less than 1 efs to spikes around i cfs, between Nle.% and Septem-
ber in 1958.
The creek may have occasional warm water fish species intro- '
duced from the lake above the stream. Summer may be limiting
juvenile rearing due to low flow and warmth. Cutthroat may
also use pools if appropriate sized gravel is nearby for use.
Aquatic Habitat
Stream structure: 1'he stream was composed of riffles, runs,
cascades, and severalsignificant pools located Ihrotighout the

Threatened and Endangered Species
A search of the Oregon Natural Heritage Program (ORNHP)
database was performed to determine if rare, threatened or
endangered species have been documented within a 2 -mile
radius of the Park. The search revealed that listed species of
fish. wildlife and plants may be found in the vicinity of the
Park. The species and their status are summarized below.

In addition to the permits from the DSL and the C:OE, the Citi

the Department of Environlmental Quality (DEQ). Section 401
of the Federal Clean Water Act, requires that applicants for
wetland fill projects compl with state water quality standards.
In Oregon, these are administered by DEQ. DEQ has prepared

Federal regulations define the limits of COE jurisdiction on
"nontidal waters of the U.S." as the "ordinary high hater mark"
(33 CFR 328.=40), on st.reanls where adjacent wetlands are
absent. The ordinary= high water mark can be determined by a
line on the shore or bank established by fluctuations of water
indicated by physical characteristics including: a clear, natural
line on the bank. shelving, changes in soil, destruction of terres-
trial vegetation. or presence of litter and debris. Typically, on a
creek such as Oswego Creek. the ordinary high water mark on
the stream bank can be determined by a scour line that hes
below the top of bank. Thus, the line of DSL jurisdwt Ion Is
typically higher than that of the COE. The ordinar\ I Ilgh water

There are two primary roadways located within the general
vicinity of George Rogers Park. State Street (OR 13) is a major
nun t h -south roadway connecting Lake Oswego with Portland to
the north and the cities of\\'est Linn and Oregon (pity to the
,(rulh (see Figure 11). The other major roadway is McVey
:Avenue. \lc\'ev Avenue serves the southern half of Lake Os-

roadwa.vs provide regional access to George Rogers Park. Film
Direct vehicular access to the park is provided by several local _ K
roadways located off of State Street. One of the access routes is
the Green -McVey Street./State Street intersection. Green Street
is a dedicated park access road serving the southern half of the Green Street Entrance, looking west towards

For circulation purposes, Furnace Street provides a roadway
connection along the east side of the park between Ladd Street
and Green Street. This roadway connection is restricted to
southbound vehicle movements in order to reduce cut -1 hrough
traffic on neighborhood streets. As a result of this circulation
restriction. all vehicles on Green Street are not, permitted to

Pedestrian Access and Circulation
The major regional roadways serving George Rogers Park have
sidewalks and signalized pedestrian crossings resulting in good
pedestrian access opportunities to the park. Although pedes-
trian opportunities are provided along the major regional access
street.,.,, several of the nearby local streets lack sidewalks. 'These
streets Include Uvld Street, Furnace Street. \Wilbur Street. and

available park parking to 121 spaces. On -street parking along
the north side of Ladd Street is restricted to residential use
only.
In order to evaluate the utilization of the parking areas, parked
vehicle counts were conducted on a mid -week afternoon in
October. At the time the counts were conducted, soccer fields,
the playground, and hiking trails were in use. Table 7 illus-
trates the parking lot utilization figures during four separate
observations between the hours of 4:00 p.m. and 6:00 p.m. In
general, it was observed that park patrons who were visiting
the athletic fields, tennis courts, and children's playground
parked priniarik on Ladd Street. The large parking lot at the
southeastern portion of the park was mainly used by prink ,
patrons using the hiking/nature trails it was also observed that

Although not officially designated a parking area. nearby
homeowners observed that park users sometimes park on
Furnace Street, Wilbur Street, and Durham Street during
special events and organized park activities (a listing of some of
the larger special events and organized activities is provided in
Appendix B). Residents also indicate some violation of the
residential parking restriction on the north side of Ladd Street.
Although the parking conditions are a source of some frustra-
tion, residents are generally accepting of the conditions since
most problems occur during infrequent and pre -scheduled
events. Parking impacts are highest for residents of Ladd

Traffic Volumes and Peak Hour Operations
The State Street intersections with McVey -Green Stret-t,

routes to the George Rogers Park. Manual turning movement.
counts were obtained at the three study intersections in October
2001. The weekday evening counts were conducted between
1.00 p.m. and 6:00 p.m. and the Saturday mid-day counts were
conducted between 10:00 a.m. and 1:00 p.m. Appendix F con-
tains the traffic count data sheets used in this study.
Current Intersection Operations
All operations analyses described in this report were performed
in accordance with the procedures stated in the 1997 1lighwa\
Capacit}- Manual. The three study intersections are sill located ,
along an ODOT facility (State Street) and as a result fall Imdur
the operational,jurisdiction of ODOT. For ODOT controlled
intersections, the amended 1999 Oregon Highugy Piaci (Kefer- '
Price 1) requires a volume -to -capacity ratio derived from a t\\ o -
hour peak operating condition be used as the intersection
operational performance ineasure. According to Table i in the ,
1999 Oregon Hightcgv Plan, intersections along State Sireet are
required to operate at or below it maximum volume -to -capacity
ratio of 0.99 during a two-hour peak traffic condition' I
The weekday p.m. and Saturday mid-day traffic vollunes and
operational analyses for the study intersections are illustrated
in Figures 1;, and 16 respectively. Based on the most recent
signal timing data obtained from ODOT, the operational perfor-
mance at the study intersections was calculated. As shown in
Figures 16 and 17. all of the study intersections are functioning
acceptahh according to ODOT standards These operating
conditums closely match what was observed In the field.
It should be noted that the ;Mate titrt t t'\Ic\'e\ :\revue infer

drop adversely impacts the lane utilization of' the southbound
approach as drivers begin to anticipate the lane drop before
traveling through the intersection. As a result, it, was observed
that the outside through lane has a utilization of approximately
twenty percent of the inside through lane. This feature was
accounted for when calculating the operations of the intersec-
tion.
ITraffic Safety
The crash histories of the respective study intersections were
reviewed in an effort to identify potential intersection .safety
issues. Crash records were obtained from ODOT for I.he five-
year period from January 1, 1996 through December 31. 2000.
A summary of t he crash data is provided in Table R t hat
includes the type of crashes over the five-year analysts period at
the study intersections. Because motorists may not report some
crashes, or because the property damage limit was not
exceeded, not all crashes that occur at an intersection will show
up in the data.

protected/permitted phase. has been the subject of smoo dehate
in the past
In 19`17. the City of Lake Oswego and ODOT evalw I ed t he
potential Io reconstruct the intersection due to coilit i\ oil
ing northbound State Street vehicles making a permitted left -
turn (green light with no left -turn arrow) onto MvVeN, Al cnnc.
ODOT analyzed several mitigation options for the intersection
that included dedicated northbound and southbound left -turn
lanes on State Street and widening of the Oswego Crf,rk In edge.
However, due to infrastructure costs and the e.t iiwited degra-
dation that these improvements would have on Iht• Iraffic �IRnal
oprninon, it was determined that these impro\(,iiwnls w(•rc
not feasible at the time. As a compromise. MOT agreed to
install a short protected phase (green left -turn arrow) to the
northbound left -turn movement on Slate Street as a means of
reducing the potential for future collisions. 'Phis protected phase
was installed in mid 1998.
Table 9 shows a year -by -year tally of the northbound left -turn
crashes that have occurred at this intersection since 1996. The
table shows that since 1998 (the year that the protected left -
turn phase was installed) the number of northbound left -turn
crashes has declined, but that the protected phase has not
completely 0iminated the vc,hicle collision type. 11 may he that
the crashes are occurring during the pernutted portion of the
signal phase. (liven that there are only two years ofcrash data
since the installation of the protected left -turn Ilh,lse. it would
be premature to draw conclusions regarding the s;Ifet l henefits

Summary of Existing Conditions
Pedestrian access to/front the park and surrounding neighbor-
hoods/htisiness districts is adequate. However, pedestrian
circulation and connects itv within the park is limited. There
are no dedicated connections between the formal park uses in
tilt, western portion (soccer fields, children's play area, etc.) and
hiking/nature trail connections in the southeastern portion of
the park. lin addition. pedestrian connections between park uses
and the parking areas are limited.

number of trips :recessing the park is relatively low: but during
special events neighborhood curt -through traffic caul be
significant
Parking areas serving George Rogers Park can accommodate
approximately 121 vehicles which is ample capacity for typical
conditions Ilowever, Ladd Street is used for it significant share
of parking. rather than the designated parking lots along Green
Sl i vet. This is due to the us(, of Ladd Street as it primary access

Appendix C Existing Building Evaluation
A site visit was conducted at George Rogers Park in the City of
Lake Oswego to review the six primary building structures
within the park. These structures included:
Concession Building
Upper Picnic Shelter
Rest.roonVINlaintenance
Bandstand
Lower Picnic Shelter
Lower Restroom
The Intent of the review was to evaluate the Innctltlnal :and
programmatic seivices the buildings provide. gait a better
understanding of the character of the structures, assess the
general condition of each building and record any deficiencies
observed. The building evaluation for each structure is broken
down into four categories: 1) General Description / Building
Data: l) Design Consultant Drawings: 3) Observations: and. 1)
Maintenance / General Recommendations. It is intended that
(lie general recommendations provided with each building
evaluation be used as a starting point to determine a more
comprehensive approach to develop a series of cohesn-v and
integrated maintenance and upgrade strategies.
Supplementary information, where provided used to assist ut
the development of this report is indiemed \++ nx stsuremenis
were taken to confirm as -built condhtuul� h,m(-\,-t flnsed upon
the walk-through at appears that the m1m nt;tt ion indicated on
the drawings is generally correct with regard to the architec-
tural features. The dimensions noted on the drawings provided
were assumed to be correct for the purpose of this evaluation.
Curt Mtngis, the manager for George 1Hogers Park, was helpful
in providing access. background uiformat i,m usage patterns
and an ovem-w\\ of itvnu requiring attention fin• the Parlous
structures. Of particular interest was mention of the fact that
vtuidaltsm in the park is not prevalent.
Assessment and vi-rtftcatton ofbudding compiruuc with the
'American with lltsabalattes Act" (ADA) and ;ggshc;ddv budding
codes is not included as part of this evaluation ho\tt'yer the

buildings and review of the provided building docunwnls. No
destructive testing of building components was conducird:
hence no responsibility is assumed for evaluation of concealed
conditions. defects or components.
Concession Building
General Description/Building Data
The concession building is a free standing structure located on
the North side of the playing fields, approximately 300 s.f. in
arca. The building consists of'a slab on grade, concrete masonry
walls, a gable roof fabricated with wood truss roof framing
members and a standing seam metal roof. The concession area
occupies the western portion of the building while the eastern
portion of the building is used for storage. Each area is ac-
cessed by its own door located on the wast and cast side of thc•
building respectively. internally. the two spaces do not conunu-
nicate with one another.
Design Consultant Drawings
No drawings were provided for the structure.
Observations
Overall, the building appears to be in satisfactory condition.
The building form and detailing is unique to the park: it does
not have any significant or notable architectural features and
does not contribute to the overall aesthetic nature of the park or
relate to other park structures. The most significant issue thal
needs to be addressed is water infiltration along the north wall.
The Foundation drainage system. if one exist.. is not functtun-
mg. This has allowed water to penetrate the concrete masonry
,,Nall and collect within the building. Water infiltration may
hn\�� llso have occurred Under the doors as mud \was observed

Maintenance/ General Recommendations
• The interior and exterior finish coatings arvIired'.
Updating these \would improve the general apiworanev
Of I he building.
• The hudding interior is in need of an aggressive
cleaning.
• 1•1)date the detailing and finish surfaces to be more

consistent with other park structures.
• Dry rot was observed at the base of the door frame trim
at both doors.
• Regrade at each of the doors and provide concrete pads
to alleviate water infiltration.
• Remediate the water infiltration problem along the
North Hall.
Install a gutter along the North side of the building to
control nater runoff.
• ILepair portions of the plywood soffit under the eave at
the North side.
• Update access to (lie building from Ladd Street and
provide pedestrian control at the berms.
• Provide a minimum of one A)A compliant service
counter. Roth service counters are not .SDA compliant.
The counters are i,3" A.F.F. which exceeds the• ADA
requirement 436" A.F.F.
• Determine the desirability of providing exterior light-
ing. None was observed. A natural lighting s''stenl
could he integrated if the structure is renovated. Addi
tionally. the use of new exterior lighting nla' provide an
oplwrtunity to develop a park -wide lighting strategy
that \hour(] help establish both visual consistency
throughout the park and to consolidate lighting mainte-
nance.
Pipes are not insulated.
Upper Picnic Shelter
General Description/Building Data
The upper picnic shelter is located on thecEast side of the
pl;l\ ing fields adjacent to the tennis court and the restroom/

Maintenance/General Recommendations
• The underside of the roof deck should be cleaned.
• The building signage should be cleaned.
'
• Finish surfaces are in need of refinishing.
• Lighting is hnuted to one ceiling mounted light fixture.
• The roof leaks
'
and the cedar shakes show signs of age.
• The budding paper between the skip sheathing and the
cedar shakes has deteriorated and should he replaced

Observations
As one of the most recently constructed buildings in the park
the restroom/maintenance building appears to be in good shape.
It is generally consistent with the other structures in the park
although the scale of this structure is relatively larger with less
surface relief. From a security standpoint the restroom facili-
ties provide ample natural light and no significant hidden
corners — it is easy to fully assess the situation upon entering.
Both restrooms proNlde two stalls and one lavatory that appear
to be A -DA compliant.. Natural light is supplemented vvith a
single fluorescent light fixture in each restroom. The restroom
relies on natural ventilation. In lieu of doors the restrooms are
provided with a gate type door that is locked in the open posi-
tion while the facility is open for use Thc, maintenance area,
which occupies the lower level, utilizes the adjacent topography
and landscaping to reduce the visual impact, as well as provid-
ing clear access to Old River Road. Both the storage and work
areas appear adequate with respect to space allocation.
Maintenance/General Recommendations
A roof leak was observed above the mechanical chase
where the vent stack penetrates the roof.
The cedar shakes are showing signs of age.
The facility is provided with porcelain toilets and
urnnals. which can be prone to vandalism to less secure
locat tons.
• There is no gutter along the roof edge at the entrance to
the restrooms. Significant water runoff was observed.
• Ii,estroatn signage is not ADA compliant.
Lighting at the restroom entry is limited to one ceiling
mounted light fixture.
The concrete floor did not appear to he staled or, the
sealer has worn off.

Bandstand I
General Description/Building Data ,
The bandstand is a freestanding struci tire located in t hr Memo-
rial Garden and is approximately 200 s.f in area. The building
is open on all four sides and consists of a raised platform with '
exposed concrete support piers, a wood framed floor, standard
wood framing support columns and a wood framed shed roof
with asphalt shingles. The platform is accessed via a ramp on I the back of the s ructure.
Design Consultant Drawings ,
No di-im nags have been provided for the structure.
Observations '
In concept the structure gestures toward the heavy timber
construction utilized with other structures in the park although
the framing is not technically considered a heavy timber framed
structure. There are no building services provided to the
structure. ,
Maintenance/General Recommendations
Some of the hoards on the ramp show signs of decay and ,
should be replaced.
•
Finish surfaces are in need of refinishing. The paint
color varies from the structures adjacent to the playing '
fields.
Limited water damage was observed at the cdge of'the•
III\ wood roof sheathing along the rear of tht, shed roof.
I n>talling drip flashing or a gutter would help control
i u rt her decay.
The roof'should be cleaned of moss and other accumu- ,
latvd organic debris.
An awkward condition exists at the bottrnn of the ramp '
where it ahuts� up to (lie concrete pier foundation. The
landing surfncl• is nnl'ven. Providing a pad M the base•

General Description;'BmIding Data
The lower picnic shelter is located in the :Memorial Garden in
close proximity to the bandstand. It provides approxintatelY
720 s.f. of covered arca. The shelter is open on all sides and
consists of a slab on grade. hea-v1• timber columns and roof
framing members and a cedar shake roof. The plan is based on
a nine -square pattern with the roof form consisting of a series
of four shed roofs radiating from a central square opening in the
roof. A fixed grilling area is provided in the center of the
structure.

Observations
lnt.erestingl)•. the building does not provide significant weather
protection during rain events There are no building services
provided to the structure. Ofspecific structural concern is tht
rotting / infi•stat.ion observed at the bases of 3 ofthe 1 wood
columns. A structural engineer should evaluate this condition
tMaintenance/General Recommendations
• The concrete slab is out of plane at two locations.
Ll
There is no direct connection with the slab at the picnic
shelter and the adjacent concrete path. Access from the
Imf h to the picnic shelter crosses dirt and may be
difficult to negotiate for someone with a disability.
Spacer hoard.- are missing between the concrete slabs.
The joint width is approximatel'v 1". from edge of
concrete to edge of concrete. The dispant} in alignment
between adjacent slabs is exacerbated b. the increased

well as a mechanical c.haselstorage area and is approxinnately
364 s.f. in area. The building consists of a slab on grade,
concrete masonry walls, wood roof framing members and hip
cedar shake roof.
Design Consultant Drawings
Robert E. Meyer Engineers, Inc.. dated December 1975.
Observations
The building is discretely located within the landscaping
adjacent to the trap of the boat ramp. Overall, the building
appears to be in reasonable shape but is showing signs of age.
Although the materials are relatively consistent with the other
structures in the park (i.e. concrete masonry walls, cealnr shake
roof) the restroom building has its own unique aesth(it u t ►f .all
the buildings evaluated, this building was the most aflectcd ))\-
vandalism, even though the amount of vandalism %%-;o, luuncd.
It as ,a�sunu•d that the vandalism is due to its remote loc;at nrn.
Add,t a rnally, for this same reason. this building seenled to offer
little in the way of a sense of security. Whereas upon entering
the facility it is easy to fully assess (lie situation. taking the
initiative to use the facility seemed to be the biggest hurdle.
Maintenance/General Recommendations
• Provide a greater sense of'securit}• around the perim-
eter of the facility.
A sidewalk is illustrated on the original Construction
Documents that connects the drive at the boat ramp to
the sidewalk leading to the grill pits and iron smelter.
The s►dew,all: has not been ►nstallcd. Til"re are no hard
connections toadjacent djacent walkways.
Lighting at the restroom entry is limited to oue soffit
inotnat.ed light fixture. A snnilar fixture is located on
the West side of the building above the mechanical
room door. Additional arra hghling should he consid-
ered.
• Interior lighting is provided by Iwo surface nunlit ed

incandescent fixtures. Replacing the fixtures with
fluorescent lights would reduce both maintenance and
energy costs,
• The gutters have corroded and need to be replaced.
The cedar shakes are showing signs of age.
The interior and exterior finish coatings need to be
cleaned and generally are 'tired'. Updating these would
improve the general appearance.
• The concrete floor did not appear to be sealed. or. the
sealer has worn off.
• An opaque coating has been applied to the transom
windows. This coating shows signs of vandalism and is
not of a very high qualm- Imish. One window is broken
and the frames on sonic of the other windows are out of
plane. Replacing the windows with a more vandal
resistant, opaque glass and repairing the flames would
improve the overall image of these liter and increase
natural light.
• The exterior creen walls impede on the required clear
dimension at t he restroom entrance doors
• The vent llatl n grilles on both doors are damaged and
should be replaced.
• The door closers do not appear to be ADA compliant.
• Restroom signage is not. ADA compliant.
• The toilet partitions are plastic and have been vandal-
ized. Removing the vandalism has created
variations in the finished surfaces.
The stalls are not ADA compliant. Grab bar have been
'
provided.
• The facility is provided with porcelain toilets and
urinals which can be prone to \'andalis;m In less 6ecure
locations.
• Consideration should be given to installing hand dryers.
None are provided.
• The pipes in the mechanical chase are not insulated.

Executive Summary Master Plan Summary
,urge Rogers Park is in historic landmark in the City
f Lake Oswego, as the site of much of the town's
industrial origins and as the result of a significant civic
effort t.o create a downtown park. The park is immensely
popular. serving a broad-range of recreational needs in the
community and occupying a prominent location on the
Willamette River and Oswego Creek.
The George Rogers Park Master Plan outlines a comprehensive
vision and a long -ranged, phased implementation plan for
improvements to the park to enhance existing recreational uses
and improve overall park utilization, interpret the park's
cultural heritage and natural resources, and to resolve identi-
fied issues in the park, including storniNvater drainage prob-
lems. Neighborhood parking conflicts, and protection of the
Oswego Creek and Willamette River habitat corridors.
The master plan consultant team of landscape architects.
historians, environmental specialists, architects, and transpor-
tation engineers performed a detailed analysis of the park's
cultural and natural resources and characteristics, which is
summarized in the Ini cii/m'v an(I.Inalysis section of the
George Rogers Park 1I/usler Plan.
An extensive public involvementeffort was included in the
master plan process, interviewing park stakeholders from the
'
region. in the community, in (lie neighbhorhood. and special
interest user groups. Public workshops and meetings were
held to identify good things, not so good things, and dream park
'
visions for the park. 'Three concepts were developed (o explore
alternative park inlpro\cnumt scenarios and ware used to
identify a preferred development plan through extensile public
and City comments. The preferred development plan was
presented in a public open house, incl in an inter -agency meet-
ing with City staff and was recc�l\ cd \\ 1t h broad consensus from
disparate parties. The preferred plan has been refined to

Introduction Overview
Oswego Creek Natural Area Corridor beneath the Highway 43 bridge
gorge Rogers Park is an historic park located in the
heart of downtown Lake Oswego, at the confluence of
the Willamette River and Oswego Creek. The park's
site history is integral to the community's origins as a pioneer
industrial town, with its prominent location on the river and
its rich natural resources.
The park encompasses 29 acres that includes two softball
fields, a soccer field. two outdoor tennis courts. a popular
children's playground, two covered picnic shelters, memorial
gardens, two restroom facilities, a Sister City Garden, an
historic smelter relic from the City's industrial past., a
Willamette River sand beach. as well as local and regional
trails through the park's riparian naturalized areas.
This well -loved, and well -used park is showing signs of wear
and tear. Recent planning efforts in the City to address open
space planning and parks and recreation have emphasized the
' significance of the role George Rogers Park plays as the heart
of elle Citys open spike system, with Its 11i1tUral resources,
scenic views and vistas. Its historical importance in the City's
past, and its prominent downtown location.

George Rogers Park Master Plan
Introduction Master Plan Directive
T
he City of Lake Oswego initiated the master planning
process for George Rogers Park as the list ofl)i-ol)osed
improvements to the park became quite loiigtlyy and
unwieldy. It was decided that a comprehensive view of the
park was needed to define a vision for the park, identify goals
and objectives for its use and maintenance, and determine how
the park was to be programmed for public recreation activities.
J::'- '—)twc behind Concert Lawn The consultant team of landscape architect.s, historians,
natural resource scientists, architects, and transportation
engineers was engaged to facilitate a public master planning
process for George Rogers Park with the final product to be a
narrative plan for phased improvements and implementation
recommendations.

Introduction Master Plan Process
he master plan process was designed to occur over a
nine-month period, beginning in October 2001 and
completing in June of 2002. The process moved through
five stages of planning:
i Establish Groundwork for Planning
I I I nvent.ory and Analysis
III Develop Master Plan Alternatives
I \ I(lent .ificat.ion of Preferred Master Plan Concept
\ Document Master Plan.
In Stage 1, the consultant team collected existing background
information from the City regarding the Park's condition and
use, its stsuct.ures and facilities, and key stakeholders related
to the park. Asurvey was initiated to determine the physical
characteristics of the park and the location of legal houndaries,
easements, and utilities. Aproject kick-off meeting was held to
introduce the master pian process to key community stakehold-
ers and City Staff.

Stage 11, Inventory and Analysis commenced with a series of
focus group meetings to examine George Rogers Park from a
regional, a community, and a neighborhood perspective, as well
as to interview special interest user groups of the park, includ-
ing team sports, water recreationist.s, the Lake Corporation,
and park operations and maintenance. Each of the six meet-
ings centered around three common inquiries: describe favorite
features of George Rogers Park describe dislikes, or issues that
needed to be addressed; and finally, if the park could be a clean
slate, what. would be its ideal features and amenities. Minutes
from each of the public meetings were posted on the City of
Lake Oswego's Parks and Recreation Department web site.
Concurrent with the public involvement focus Interviews, the
consultant Wain led detailed investigations into the parks

In Stage 111, the consultant team metwith the City of I,;II:e
Oswego to identify the scope and direction for the master
planning concepts, based on anticipated funding and develop-
ment priorities. Three master plan concepts ware designed to
engage public comment on specific issues of park development,
including the relocation or removal of park elementsparking
,
and circulation alternatives, and general programmmig for the
park. with concepts ranging in order of magnitude concept A
described simple improvements to the existiiig p,lrl: contigura-
'
tion. Concept B relocated existing uses and accommodated
substantial renovations in park facilities. Concept. C described
a completely redeveloped park, examining new parli features
'
and configurnhons. The developed concepts were presented in
a general puldic meeting and then displayed for public- review
and comment. 1'uhllc response to the concepts was substantial
and formed the basis for the development of a preferred plan.
Stage IN' of the master plan process identified a preferred plan
,
for park development describing the park's spatial organiza-
tion. features and components, and-,ynthpsizing preferences
and identified concerns identified from the concept alterna-
tives. The preferred plan was reviewed with City staff and
related agencies and presented in an Open House and on the
City's project website to the general public. The Preferred Plan
received positive support and general consensus on the design
and its features from disparate interests.

Public Process Analysis
1 Porge Rogers Park is Lake Oswego's oldest. and one of
it's favorite public spaces. Called "the jewel" of the
Lake Oswego park and recreation system, this well -
loved and well used multi-purpose park serves diverse demands
for regional trail connectivity, team sport venues, community
festivals, and as a neighborhood's backyard.
The master plan process was designed to engage the public in a
discussion of the park, its features and functions, and its
prominent role in the life of the community. Throughout the
projectthe community was involved in the analysis of the park,
the review of concept, alternatives for development., and the
approval of the preferred plan for a long-term park vision.
To understand the park's many roles in serving the community
of Lake Oswego and the surrounding region as a whole, a series
of focus meetings were designed to examine the lark at mul-
tiple levels of park functionality, moving from regional park
and open space goals and objectives to the everyday function,,.,-
of
unctionsof the park's operations and maintenance.

A schedule of meeting dates and the minutes from each of the
public meetings were made available on the City of Luke
Oswego's Park and Recreation Department's website, through a
link to the George Rogers Park Master Plan Process.
The stakeholder kick-off meeting, the regional focus group
meeting, and the special interest focus group meeting with the
Lake Corporation varied from the common format use([ for the
majority of the information -gathering public process to better
accommodate the specific information requested of the meeting
participants. A sununaiy of these three meetings and their
objectives follows.
Stakeholder Kick -Off Meeting
The consultant team worked with the City of Lake Oswego to
determine a list of key stakeholders Involved in the use of
George Rogers Park to be consulted in tho park's master plan-
ning process.
The stakeholder kick-off meeting invited representatives of
each of the interested organizations to introduce the consultant
team, describe the intended master plan process. and to brain-
storm a master plan vision and process goals, identify potential
park issues, and discuss preliminary programming for the park.
While not anticipated to be comprehensive, the list of stake-
holders was developed to represent as much as possible the
mane' varied interests that use the park. These interested
parties included:

'
Effort was made to ensure a uniform format to each nreeting,
thereby creating comparable meeting results. Meetings cen-
tered on a common agenda to identify "good things", "not. so
good things". and "dream park visions".
'
Good Things ,
George Rogers Park is extremely popular in the conununity,
offering it variety of activities and recreation opporttinituw
including team sports, nature access, historical interests. incl ,
large open areas for play and picnicking. The multiuse charac-
ter of the park is extremely important to the conininnity,
offering something fbr everyone to enjoy. The park is cent rally
located, and is one of, the few public open spaces nvailable ni the
conimunit.y, and as such, is popular for (i st n ;l Is. tn•achtonal
event_,, and community gatherings. '
n
Favorite events include the Festival of the Arts, the qtk of July
Pancake Breakfast, and Easter Egg Hunt. The park's scenic
setting at the confluence of two waterways offers unique
opportunities for beach access, fishing. and canoeing. More
than half of the park is preserved as a forested natural area in
conjunction with Oswego Creek and its steep ravine, offering
opportunities for informal trail connections to regional
greenwav ,Ystems.
—'
Not So Good Things
Despite its popularity, there were many things that were
identified as concerns and problems in the park. Of particular;
concern was the lack of a circulation system throughout the
park. There are a handful of sidewalks that go nowhere, are in
disrepair. or simply too narrow. Universal accessibility to
mayor park features was also a concern. given thatthe park

oiwn ,ryas that are not pleasant for recreation.
The traffic eircillat.ion and demand for parking is inefficientin
the park tt it h the highest demand creating a strain on neigh-
borhood streets, while parking spaces in the park go unutilized
as they are remote from the activity areas.
Because the terrain of the park is made up of terraces divided
by steep slopes, there is a lack of unity to the park that con-
nects one activity area to another. There is also no park
"center'. Activitv in the park is clustered into a few key areas
like the Children's 1'lav Area. Memorial Gardens, and Athletic
Fields, while other parts of the park are underutilized — the
Concert Meadow. the Sister City Garden. and the Barbeque
Terrace.

The park iweds it stronger visual presence on State Street, with
it defined entre for both pedestrians and automobiles. Cm-
'
rently there is no defined park entrance, with significant grade
changes occurring along both State and Ladd Street, and no
access available from I lighway 43, to the south.

Dream Park Visions
When asked to imagine a brand new park with a clean slate of
program and facilities, the visions ranged from the simple to
fairly elaborate. Interpretation of historical as well as natural
resources was emphasized to include explanatory signs, it
museum/visitor center, and archaeological digs or monuments
to illustrate the location of historical elements. Buildings and
park structures would have a common design theme to inte-
grate them and integrate art and history in their design. New
facilities were proposed, including a swimming center, skate
park, croquet and boccie courts. and a floating dock. Facilities
to be improved and/or expanded included the Children's Play
Area, the ball fields, group picnic pavilions, and picnic areas,
and the park itself. Kestoration of the historic smelter and
barbeque terrace was emphasized.
Program Summary Community Workshop
To conclude the inventory and analysis phase of the master
planning process, the consultant team summarized the com-
ments from each of the focus group meetings and provided a
technical analysis of the park's existing conditions, including
historical research, natural resource assessment, architectural
evaluations, transportation analysis, and park features. These
technical reports prepared by the consultant team are summa-
rized in Invenlory an(l Anal•sis /or the 1llasler• Plan of George
Rogers Park, May 2002. The Program Summary Community
Workshop provided the public opportunity to hear the consult-
ants' assessment of'the park. to identlfvanv issues overlooked,
and to build consensus on issues and opportmiihes to be evalu-
ated in the c tmc(�ptual design phase of the master plan process.

Public Process Concept Development
n designing concept alternatives for the future develop
nnent of George Rogers Park, the consultant team began
with a list of basic improvements to be common to all
designs. This list was generated from baseline consultant
recommendations from the analysis of the park and/or were
consensus items drawn from the focus group interviews and
public discussions.
• Remoual of the lower parking area adjacent to Ih.e
Memorial Gardens. The lower parking area was
determined to be a significant detriment to wildlife
habitat in the Oswego Creek Natural Area due to its
proximity to the creek and the unrestricted storniwater
runoff from its surfaces. The parking area also occupies
a large amount ofspace immediately adjacent to (lie
historic smelter and Memorial Gardens to provide
parking and related turn-around movements. As the
park is limited in its amount of large. flat open areas,
they use of the area as a parking lot did not appear to be
the most. efficient and effective use of available land.
• Improve path circulation in park. Paths that provide
access to and connect park features were deemed
critical to the park's future development. Looped
circulation routes that offered a variety of experiences
of the park would be inherent to any scheme for the
park.
• 11Ilrirrluim existing uses in lhr park. The existing mix of
mulliple uses in the park i, extremely popular within
the community and it was thegeneral consensus of the
public that for the most part. the status quo of park
uses should be maintained.
• Restore: beach habilal. An existing boat ramp is located
on the Willamette River beachfront that is in disrepair
and no longer utilized for launching boats f'or recre-
ation. The boat ramp will be removed and the beach
will be restored.
• Derelop accessible routes to all major park lealu res. In
addition to overall path circulation within the park, it is
required that every major feature ofthe park be made
universally accessible.
• Alanage slormiroler runoff an,i Imi>rove lrcrrlc drainage.
The park has significant issues \c u h stornnwater runoff
from neighborhood streets and iwornal park drainage
that have degraded natural hahwo areas and limited
the use of n-creation areas. Thesc problems will need to
be addressed for any park development

Public Response
The three concept alt.ernanvc,� were pi,ented to the commu-
nity in a public meeting on February . 2002 and then dis-
played on the Internet and in City Hall for a two-week period to
allow for comments.
Feedback tended to prefer Concept A as it proposed the least.
amount of change to the park. Major concerns for the concept
included the provision of t.00 much park parking on Ladd,
creating a burden for the neighborhood. The athletic fields
were recommended to be flipped towards Green Street to
alleviate the need to park on Ladd, and the removal of the
lower parking area adjacent to the Memorial Gardens raised
concern for convenient access for elderly walkers, its well as
concern for a net loss in available park parking.
The looped nature trail proposed in Concepts B and C was
much preferred over the extended trail shown in Concept A its it
was less invasive to the natural arca. The removal of Furnace
Street also received positive comments for the anunrnt of open
space made available.

A Preferred Plan
Given the significant public response to the concept. aherna-
t.ives, the development of a preferred plan sought to overcomP
the defined obstacles of parking on Ladd Street, ivanaging
st.ormwat.er runoff, and providing limited vehicular access to
the Memorial Gardens terrace. The preferred plan was re-
viewed by cite departments and then presented to the commu-
nity at an Open House on March 21, 2002. Comments were
very positive and supportive.
The preferred plan has been only slightly modified to become
the George Rogers Park Master Plan. ReNisions have included
improvements on Ladd Street from parallel parking and side-
walks on both sides of the road to become a "green street"
providing clustered parking for both the park and residents and
integrating st.ormwater swales and plantings with a sidewalk.
The "green street" approach was presented at the Open Ilouse
and was widely supported I)Y neighbors as a wa.y to limit park
,
parking and to also maintain the country lane character they
curmntly enjoy.
S
Other changes to the preferred plan include providing emer-
gency vehicle access to the limited parking area adjacent to the
IN4emorial Gardens and providing access to launch eniergencv
rescue boats from the new canoe launch area. The concessions
that were originally located in conjunction with the program
facility and rest -rooms to the south of the Children's Play Area
have been relocated to the proposed storage facihlN m1picent to
the Green Street ballfield. This relocation was dmw m re-
sponse to concerns raised by the Team Sports groups that the
concessions were too remote from the fields and required
crossing a vehicular accessway.

Master Plan Overview
The historic smelter. a relic from the site history of George Rogers Perk
he objective in developing a master plan for George
Rogers Park was to identiA, and sequence improvements
thatare necessary in the park and to develop a long-
range vision for the park to provide an overall framework that
would unify the park and enhance the significant role the park
plats in the life of the Laker Oswego communitN.
The vision for George Rogers Park is a community park that
offers ;t \ariety of recreational opportunities that Include
athletics_ play, picnicking, and hiking. The parks downtown
location, scenic context, and large open spaces make it ideal for
community festivals and gatherings.
Because of the uniqueness and historical importance of the
park's site, the themes of history interpretation and natural
reslulrce protection and enhancement characterize the improve-
jiwiii p1mi for the park.

Maetar Plan . Site Development
ho master plan for George Rogers Park retains t lie
existing uses of the park, making improvements in
function and aesthetics, with a few significant overall
site development changes.
The most significant site change is the vacation oft he V nrnace
Street right-of-way in the park. In the master plan design,
Furnace Street terminates in the park adjacent t.o the Furnace
Street residence immediately to the north of the park. By
removing the Furnace Street connection from Ladd Street to
Green Street, the park becomes less compartmentalized. With
the additional removal of the lower parking lot adjacent to the
Memorial Gardens and I list.oric Smelter, traffic circulation
impacts are minimized in the park, allowing for broader
uninterrupted open spaces for recreation.
The removal of the Furnace Street connection between Ladd
and green Streets is replaced with a Green Street loop that is
located west of Furnace Street and 130 -feet east of the Durham
Street alignment.. The Green Street. Loop is a proposed park
road to minimize traffic impacts in the adjacent. Old Town
Neighborhood by providing one-way circulation into the park
south from Ladd Street to the Green Street parking area.
With the above mentioned adjustments in the traffic circulation
in the park and associated site redevelopment, the overall
structure for the parks improvements was defined.
Art in the Park
Redevelopment of park facilities will allow for opportunities to
use art as an integration tool in the park, and create a unique-
ness for the park and its structures, appropriate to 1he City's
oldest park. located in the heart of downtown. Opportunities
abound in the park to use art to tell of•the park site's history.
and its cultural significance to the founding of Lake Oswego.

There are several st,,ri lines to tell in interpreting h,story at the
site of Cxeorge Rogers Park:
• Euro -American settlement extends back a little m r
150 years at the sit.e. Nat.iveAmerican occupant \ (I;,ie�'
to over 6,000 ,years ago. The outlines of prehiston ;lull
the contact culture of the Clackamas Indians shoul(l I)c
interpreted at the hark.
The Oswego Landing at the north side of the mouth
Oswego Creek was an import ant. point of commerce on
the lower Willamette. Canoes, scows, barges, t ugs, and
sternwheelers used this site for the delivery and receipt
of passengers and freight. Durham began exporting
lumber from this landing in 1851 for both building
Portland as well as gold rush towns in ('Aiforma.
Trullinger's sawmill continued to use (Ills landing for
lumber export in the mid -1860s. Passengers came and
went from this site, as did residents of Lake Oswego
into the 1910s. The Landing is an ideal theme or
story1mv for interpretation of the significance of the site
in the development of Lake Oswego.
The Durham and Trullinger sawmills should he Inter-
preted at George Rogers Park. The water -driven
sawmills contributed to the damming of Sucker Lake
cutting of the'Rialatin Canal, and development of Lake
Oswego. The Trullinger sawmill was a testing place for
the inventive skills of John C. Trullinger and, possi))ly,
the site of initial use of his patented water turbine and
other inventions,

tion in George Rogers could speak to the role of the
Chinese in the early history of Lake Oswego, the canal

landing as a seasonal gypsy camp in the twentieth
century.
George Rogers Park is Lake Oswego's oldest cite I m k
and honors a visionary residentand former city count 11
member. The park initially grew because of civic
interest., but without any long-term planning. As a
result, the park has supported multiple uses over more
than a half century. The Park should interpret its name
and the role George. Rogers played in helping create this
urban amenity in the town where he was a resident,
merchant, and city council member.
• The Memorial Garden is an informal garden laid out, by
volunteers, most especially the Lake Oswego «'omen :s
Garden Club. The garden is representative of the
initial civic efforts that created the park, and should be

curving stone wall creates an overlook into the park and
provides opportunity for interpretation of the park's history, its
namesake. as well as the historic role of the park site in the
development of the original Lake Oswego town site. A ramped
accessway provides an accessible pedestrian entrance into the

Ladd Street Improvements
Section of proposed Ladd Street Improvements
Ladd Street is redeveloped as a "green street" to accomodate
stormw•ater run-off from the neighborhood and to reduce the
impact of park vehicular circulation on adjacent residences. ""'
The "green street" concept illustrated in the master plan is
based on a pilot program developed and constructed on a
similar neighborhood street in Seattle, Washington. The design
describes a narrowed road section clearly indicated by concrete
bands flush with the road pavement and has clustered parking r:::z=I
in parallel. angled, and perpendicular arrangements. This V
variety and clustering of parking accomodates the development
' of landscape swales on either side of the street to capture and
treat stormwat.er run-off. The meander of the new roadway
accomodates the irregular disbursementof parking and swalvs,
as well as slowing through traffic. A pedestrian sidewalk is
provided on the park side of Ladd Street. Parking spaces for
the park are limited to four, adjacent. to the Children'.- Play
Area.
tThe development of a "green street," on Ladd Street will require Prototypical `Green Street' improvementsin

Tennis Courts and Maintenance Facility
The two tennis courts arr retained in the master plan, although
they are reconstructed in conjunction with grading and con-
struction of the Green Street Loop connecting to Ladd Street.
The new road passes through the existing eastern most. court,
whwh is subsequently relocated south of the west tennis court.
This southern tennis court is elevated to accommodate a
subterranean maintenance facihhy accessible from Green
Street.
The maintenance facihtY remains in the park and is relocated
under the southern tennis court, taking advantage of grade
changes and in elevated court to minimize the facility's promi-
nence in the stark. The facility has a street frontage and access
on Green Street, and with sufficient space for offices, storage,
bulk materials storage, and a locker/rest.room facility for crews.
The George Rogers Park maintenance facility services parks for
the entire east side of Lake Oswego. Available square footage
for the facibtY is the size of the tennis court. 7.200 s.f., a net
increase of the existing facility by 1.200 s.f.

Green Street Parking
With the removal of on-<treet pm -king on Ladd Street and the
re -orientation of facilow away from the neighborhood as well
as the removal of the lower parking area adjacentto the Memo-
rial Gardens, Green Street becomes the vehicular spine in the
park, providing access and increased parking, so t.lint overall
provided parking spaces remain the same as currently pro-
vided, at 121 spaces. Parking on both sides of Green Street is
expanded to run continuously along the street. The south side
Of Green Street is resurfaced in reinforced grass paving to allow
fur stormwater infiltration and detention using an encapsulated
sub -drainage system. Curbs and sidewalks that parallel Green
Street on both sides will provide safe pedestrian access from
cars to park facilities, as well as providing critical linkages in
the park circulation system.

A drop-off and turnaround is located at the terminus of Green
Street near the Furnace Street alignment. This area will allow
for convenient vehicular turnaround and exiting from the park
' on Green Street., rather than infiltrating park traffic into the
neighborhood. The drop-off area provides lower park access in
two access roads, one utilizing part of the exist nig boat launch
ramp road to provide catering access to the group picnic pavil-
ion located at the Barbecue Terrace, and the other running
west of the smelter at the top of the Oswego Creek embank-
ment to provide vehicular access to a small parking area just
north of the Old River Road Bridge. The small lower parking
arca provides re,,t u•ted harking for di.sahled park users and for
canoe/kayak launch awcc. it total of four parking spaces.
Because of its proxinut}y to the Oswego Creek Corridor, the
parking lot and its access road are paved in reinforced grass t.o
Inlnimize environmental impact and to allow for stormwater

Park Circulation
A primary goal of the master plan is to integrate the diverse
park attractions and features with a circulation system that
,
provides access and a variety of experiences. The pat systems
are designed to provide accessible slopes for the majority of the
park, with a few exceptions where stairs or steeper slopes were
'
required. The path system is comprised of loops that spiral off
of each other so that the opportunity for discovery allows a

The renov <awn and restoration of the Historic Smelter is the
'
focus of a special study to assess and stabilize the condition of
the structure and to evaluate the archaeological resource
potential of this remnant of the site's industrial uses. The
'
master plan for George Rogers Park considers primarily the
relationship of this important structure within the park and
'
the opportunity for interpretation it proOdes.
In order to protect the historic structure. public access needs to
be limited. The smelter occupies a prominent location in the
N—lemorial Gardens however, and needs to be appropriately
acknowledged. The chain link fiance that currently surrounds
the structure encases a variety of garden plants. The fence:
needs to be removed and replaced with an ornamental wrought
iron fence, preferably of an historic tradition. The plantings
inside of the fence are removed so t hn l t lie smelter occupies the
more open setting of a meadow. wit hl it a clutter of non historic
plants at its base,

Master Plan - Components
The natural resource area associated with ()�,i�ego Creek and
the Old River Road Trail is a sizable area of George Rogei:s
Park, and providing public access that also proteeted the
habitat value of this resource is a goal of the Mauer Plan for
the park. The Nature Loop Trail provides a trail through a
significant portion of the Oswego Creek Corridor. providing a
connection across the Creek wit 1) a suspension bridge and
elevated boardwalk that connects with the existing park access
road for the Lake Corporations Powerhouse. Vertical and
horizontal separation of the trail protects the historic structure
from immediate public access, while providing views of the
Creek, the Powerhouse. and the Surge Tank for historical
interpretation. The loop trail is not accessible for its entire
length, due to significant slopes in the Creek Corridor, and the
emphasis on protecting the natural s'vstenis as much as pos-
sible. An overlook marks the end of the accessible pathway, and
Ilrovidos an opportunity for historic and natural resource
interpretation.
A formalized trail and signage l.hrough the natural area will
encourage users to staff• on the trail and keep clogs on leashes,
protecting wildlife nesting and bedding areas From disruption
by roaming pets and humans. and minimizing damage to soils
and plant communities.
Also located in the ilsiir; a Creek Corridor is a new facility' for
the pari:, a Nmiu•e lnivi-prent,v I'm dion. The pavilion is

platforms would provide information on the resources of
Oswego Creek and could be supplemented with additional
panels or interpretive devices along the Nature hoop Trail.
A priniary issue in the restoration of they Oswego Creek Natural
Area is the control of English Ivy within the park. Infestations
of this nuisance plant increase tree mortality as well lower
species diversity, effectively crowding out native herbaceous
species and competing with desirable shrubs and seedlings.
Once nuisance plants are controlled, the Natural Area will be
replanted with native plants that are appropriate for the site
conditions, are valuable for their food and cover for wildlife, and
their likelihood for successful establishment and growth. New
plantings will be concentrated in designated areas rather than
spread throughout the Natural Area to provide more protection
for %wildlife and to discourage random trails.
'I\hroughout the forested portions of the Natural Area and
within the stream, installation of structural elements in the
stream and forested area will enhance fish, amphibians and
reptiles. and inve\rtc orate habitat. Placement of logs or brush
piles that extend outward from the stream bank will provide
cover and organic inaterial for aquatic species as well as sun-
ning spots for turtles, etc. Other proposed in -stream habitat.
restoration measures include the addition of gravel to the
stream bottom to enhance the area for spawning.
Snags providing nesting and forage habitat for a variety of
wildlife species will be created by girdling selected trees or

allowing dead and diseased trees to remain. Creation of snags
will also create or enlarge openings in the canopy for a more

Willamette Greenway
The Old River Road bridge and trail that extends south of the
park along the Willamette River is the southern segment of the
Willamette Greenway Trail in Lake Oswego. The southern
Greenway Trail terminates in George Rogers Park, and it
northern Greenway Trail begins north of the park, just, south of
Roehr Park. There are five residential properties along the
Willamette River where an easement for the trail door not

River until access is obtained.
For the master plan of George Rogers Park. the Old River Road
segment of the trail is continued in the park, with an outlet at.
the end of Furnace Street. The proposal is to provide the
Greenway bail connection along the neighborhood sti-vet. for
the five property lengths. and to look at reconnecting the trails
south of Roehr Park.

• A stormwat.er management study for the drain
-age area of Ladd Street and the neighborhood
flowing towards the park;
• Design and development of street improvements for
Ladd Street based on a green street design minimizing

Phase 111. Tennie Courts and Maintenance Facility
Relocation
Phase three is sequenced to provide the critical Green Street
Loop Road connecting Ladd Street. and Green Street and to
accomodate traffic circulation int.o the park from Ladd Street.
prior to the vacation of Furnace Street.. With the development
of the park road, the tennis courts and maintenance facility are
displaced and redeveloped west of the road. Grading for the
roadway and pathways will achieve a maximum 5% slope for
accessibility, and will excavate the new maintenance facility
location below the southern tennis court., accessible from Breen
Street.
These improvements will replace disrupted functionality of the
tennis courts and maintenance facility, with minimal impact to
other park uses.

Phase VI. Natural Area Restoration and Improvements
The Oswego Creek Corridor will be the focus of phase six with
'
the removal of invasive plants and the re-establishment of
riparian habitat. While volunteer efforts can be used during
any of the master plan phases to help remove invasive phuit
species, the magnitude of the effort and the size of the area ,
warrant a comprehensive effort to reclaim and enhance t he
natural area. Natural area restoration will occur above the
regulatory Ordinary high Water demarcation and encompass
the remainder of the George Rogers Park Natural Area. Con-,
current %N it 11 the restoration effort will be development improve-
ments that include the Nature Loop Trail with overlook and
suspension bridge, and restoration of the Old River Road
,
historic covered bridge.
Phase six improvements will lead to a temporary removal of the '
floor of the Old River Road bridge as a covered bridge is built in
its place. No other park activities will be impacted.

moval of the lower parking area adjacent to the Garden, termi-

plants, opening up views towards the Creek and Willamette
River. Phase development will improve the context of the ,
historic smelter with an ornamental perimeter fence and the
removal of non -historic plantings.
