PLANNING COMMISSION MEETING MINUTES—July 16,2007—Page 1
• •
Duane Roberts discussed the proposed goals, policies, and action measures language for
parks, recreation, trails, and open spaces (Exhibit A). The final product will be forwarded
to the Planning Commission next month for consideration and recommendation to
Council.
The Commissioners had the following comments/questions. Staff comments are written
in italics:
• Should 6.1.3 be revised to the upward end of what's achievable? The Policy Interest
Team, the Planning Commission, and Councilor Woodruff are strongly supportive of this goal. It
was included in the Park Master Plan from 10 years ago.
• How many acres per thousand does the City currently have? About 7.7 acres per
thousand, which includes developed parks and undeveloped natural areas. Roughly, there are
about 170 acres of active parks. To meet the 11 acres standard, we would need an additional
142 acres.
• Is this an achievable figure? Does it take continuing growth into the equation?
The Master Plan says we can't meet our needs for the future. We would have to rely on
partnerships (e.g., school playgrounds. Eleven acres is intended to be aspirational. It was
clarified that this is a policy the City wants to achieve.
• Would it benefit the process to have the acreage stated in the Plan? The Resource
Document is a companion document to the Comp Plan— this information could be included in
the Resource Document.
• When is the City planning to "go after certain pieces of property" for parkland?
The Park and Recreation Board and the City Parks Division have been working on this (what
land is available;what the City and Metro policies are for acquiring land;if there are willing
sellers;and what funding is available).
• What is the potential for park acreage within the school system? Approximately 55
acres.
• Regarding 6.1.23 c, (the degree to which property meets the "site selection criteria"
for the facility type corresponding to its intended use as listed in the Park System
Master Plan),is this an established site selection criteria? Yes, the criteria are detailed
in the Park Master Plan.
• Action Measure 6.1.a talks about regularly updating the Parks System Master Plan
every 5-10 years. That seems to be a large gap. Is there an average for Parks
Master Plans? It averages about 10 years, but portions can be updated more frequently. The
City of Tigard is on a 10 year schedule. The issue in the Metro area is that things are growing
quickly and it's believed that Master Plans should be updated as needed.
• For item #1 under funding,isn't there a problem where we can only use SDCs for
a portion of park improvement, so we have money we can't use? Our current Park
SDC study is based on meeting the needs of growth. According to State law, we can charge a
park fee for new development to maintain the current level of service in the community. We can
charge the fee to developers, but we can't use all of the SDCs to pay for park improvements. On
average, 63% of that funding has to come from other sources. Up to now, that has been from the
general fund. Another problem is that approximately 47% of the capital improvements identified
in the methodology are in the unincorporated area. Since the City doesn't derive any funds from
PLANNING COMMISSION MEETING MINUTES—July 16,2007—Page 2
• .
that area, we are unlikely to build capital improvements on Bull Mountain outside the CO.
• If we don't get funding for a full-service recreational facility, how will we achieve
this goal? If a bond measure fails, the funds would have to come from City general funds.
• Could an overhaul of the SDCs allow for contribution to this? No, we can only
charge for land and facilities;we can't pay for operations or programs with SDC money.
• We should start a public awareness program now for a recreation district. We
could show the need for a program and give the reasons why we're asking for the
money. Staff agreed and suggested an action measure along the lines of `Development of
information program to raise the public's awareness of the importance of parks and recreation
facilities to the livability of the community."
• Is there enough weight in the proposed policies and action measures to be able to
start developing the code to support them and move toward putting the emphasis
on achieving them? Staff believes they're good goals,policies, and action measures. There are
basically 3 ways to accomplish the goals: through land use conditions of approval;updating the
ystem development charges;and the City's own reference to the goals,policies, and action
measures in the normal course of work. In addition, there are elements that can be reinforced by
other goals,policies, and action measures in the Comprehensive Plan.
• Do we need some kind of time restraints? Typically, we're required to update our
Comprehensive Plan every 7-10 years. We can go back and assess the implementation of the
goals and policies with the next update. Another aspect should be in the Parks and Recreation
Master Plan. The implementation schedule could be a part of that Plan. When the Master Plan
is approved by Council, they would then buy into the administrative schedule. The
Comprehensive Plan itself is an implementing document for establishing the policies.
John Frewing, citizen, noted that although Tigard doesn't have a recreation program, we
have a low tax rate —you get what you pay for. His past experience with the U.S. Forest
Service, when they had a plan for something, showed that things get done when they have
revenue for them. Some of the things that don't get done are the ancillary things. He
suggested using such language as, "We'll acquire parks in this sector of the City before we
widen Walnut Street." This would logically tie the acquisition of parks and open space to
other elements. That would be legitimate as a City policy.
Frewing believes that the current Resource Document has a lot of good technical
information that the 2007 Resource Document and these policies do not have— trends
and natural resources for example. He thinks that kind of factual information should be
in the 2007 Resource Document and the Comp Plan in order to provide a legislative basis
for policies and actions.
Frewing noted that Policy 6.1.2 states, "The City shall acquire... natural areas within a
mile..." and later on, in Policy 6.1.4, "... parks within half a mile..." The "Tigard
Beyond Tomorrow" 2004 survey listed the following issues as important or very
important: undeveloped open space or greenways within half a mile of residents (84%);
neighborhood parks within half a mile (83%). Why have we changed? He thinks the
policy should be the same as we have had.

6. ENVIRONMENTAL QUALITY POLICY REVIEW AND DISCUSSION
Darren Wyss reviewed the draft goals, policies, and actions measures for environmental
quality (Exhibit B). The Commissioners had the following comments/questions. Staff
comments are written in italics:
• On 4.1.7, it seems that noise and light pollution are misplaced in the air pollution
section. DEQ defines noise as air pollution. A lot of communities also define light as air
pollution.
• For 4.1.3, where do we go as far as developing a public transportation system?
Right now,we're restricted to 2 major lines. TriMet is our public transportation
provider. Working with them to expand the system is the best place to start. Under action
measure 4.1.d, the City would work with TriMet to identify underserved neighborhoods.
• TriMet is pretty well restricted on where their funds come from and what their
capacity is. Their primary focus has been light rail. In reality, our chances of them
developing anything in this area are slim to none. If we're going to reduce
automobile traffic, we should consider developing our own transportation system,
such as Wilsonville has. We shouldn't block off other avenues that could expand
our ability to create an intra-city transportation system that could tie to TriMet
stops. We shouldn't focus only on TriMet and Metro. Policy 4.1.3 doesn't restrict us
from developing our own ystem. Staff suggested adding the action measure, `Evaluate the
feasibility of providing local transportation options,particularly to connect with a regional transit
ystem."
• We need an action measure statement that states, "We will develop an ongoing
committee made up of citizens and staff to explore the aspect of a City
transportation system that would hook to the existing TriMet system."
• Staff advised that "dark skies"ordinances provide direction on illumination— bulb wattages,
angle of the lights, etc.
• Could action measure 4.1.g, also work in tandem with the schools? They also have
programs on pollution and recycling; this might be a way to get the information
out. There are also people who may go into the schools, but not into City Hall or
the library.
• Does 4.1.j refer to gas leaf blowers only? Yes— we will be more specific about that.
• Staff advised that.policy 4.2.3 originally read, "The City shall prohibit unnecessary
increases in the percentage of Tigard's effective impervious areas." The word
`unnecessary'was inadvertently left out.
• Policy 4.2.3 might not be very practical. Perhaps it should be blended with 4.2.7 to
achieve the goal.
• One Commissioner was thinking small scale and more of the individual land owner,
not something that was going through another permitting process. There was some
discussion on what this meant for a homeowner wanting to put in a patio. Staff
advised that the policy is intended for both the single family home and commercial development.
Regulations would have to be done through the Development Code. An important point of the two
policies is the phrase to the extent practical." That provides the common sense element to develop
standards and ordinances that are practicable and implementable.
PLANNING COMMISSION MEETING MINUTES—July 16,2007—Page 4
• •
• We need to add more detail to these 2 policies to make them clearer.
• Staff may want to check with John Floyd about verbage for 4.2.c.
• Can we add an action measure to revisit our Public Works standards to encourage
and support green development practices? There are other entities in the City (ODOT
and Washington County)whose practices also affect the City's storm water quality. They need to
be encouraged to develop ways to improve storm water quality run off Staff will develop a policy to
address this.
• On 4.2.f,what is the advantage of joining with CWS on NPDES permits? This
encourages the City to take more responsibility for storm water.
• For action measure 4.3.b, are there plates, utensils, and cups that you can compost?
Yes.
• With regard to policy 4.4.5 D,it was suggested that we add an action measure to
survey the community to find out what the top 3 goals would be regarding building,
so that we could look at incentives (e.g., density awards, tax incentives) to encourage
reduction in energy consumption. Staff is interested in engaging the community in a dialog
about energy consumption and what their concerns are. Staff will develop an action measure for this.
• Would like to see something in the policy statements along the line of what we can
offer through the City.
• Would like to see something stronger in action measure 4.4.d,perhaps using the
word "implement"instead of"research"in the sentence.
John Frewing likes Commissioner Caffall's ideas of local action for transportation. It things
it should include not only programmatic things, but also capital things such as enhancing
sidewalks close to bus stops. He suggested the idea of a fee. Maybe the street maintenance
fee could be expanded to include sidewalks.
Frewing urged the City to look at undergrounding of powerlines. Overhead lines are a
barrier to canopy cover; small trees don't give very much shade. He also thinks the City
should use a best management practice. Commissioner Caffall noted that undergrounding
existing utilities is almost cost prohibitive unless it comes with new development. Sidewalks
are also very expensive; funding is an issue. Caffall suggested the possibility of doing it in
piecemeal quantities, so that in so many years, a certain percentage of the City would be done
(e.g.,in 10 years, 20% of the City would be done).
Ron Bunch advised that the next step in the Comp Plan process will be to bring changes
back to the Commission which can be considered for a recommendation to City Council.
7. SUBCOMMITTEE RECOMMENDATIONS FOR DOWNTOWN DESIGN
REGULATIONS
Sean Farrelly updated the Planning Commission about the City Center Advisory
Commission/Planning Commission joint subcommittee recommendations for Downtown
Design Regulations (Exhibits C and D). After reviewing different design regulations, the
PLANNING COMMISSION MEETING MINUTES—July 16,2007—Page 5
• •
subcommittee decided to recommend a "hybrid" code that would incorporate a form-based
code approach and use provisions, processes, and standards of the existing development code.
Farrelly explained the 3 alternate ways to receive approval based on the complexity of the
development (clear and objective track; discretionary track; and over the counter track).
He advised that the subcommittee recommendations and Planning Commission and CCAC
comments will be taken to City Council on August 14th. The subcommittee will then meet to
finalize the regulations.
The Commissioners provided the following comments:
• A lot of existing downtown buildings may not meet any standards. What would the
impact of these regulations be on those buildings? There could be problems for buildings that
don't meet design regulations. Existing development could be considered a non-conforming use and when
it redevelops, the new building would have to meet the new code. If there was significant redesign of the
building, the new standards would apply.
• President Inman (subcommittee member) advised that the subcommittee struggled with
some of the pieces of the standards, e.g., at what point to require a major redesign.
There was a general consensus to look long-term and take a harsher approach to ensure
that long-term got us to where we want it to be.
• Commissioner Anderson (subcommittee member) noted that using form-based code is
new. Staff research found that cities using a form-based code tend to use a hybrid code.
This may be more applicable for Main Street than it would be for Burnham Street.
Hopefully,we can get the community behind the new code. We also want to get some
feedback from developers.
• Does the code address the functional realities of the kinds of businesses that we would
like in the Downtown? We have a real estate and economics consultant who is looking at the
Downtown and giving us some advice to kick-start the development. Part of that is looking at what uses
would be best in the Downtown. That will be taken into account when we revisit the zoning for the
Urban Renewal District. We want a mixed-use feel in the area.
• Some businesses require unique amenities or structural machinery, etc. Will this be
taken into consideration?
• When we get to that point,we'll have to evaluate whether we want to make
accommodations for something like that or not.
• We do have architectural review for these buildings, so we want to keep the design
standards high.
8. OTHER BUSINESS
The upcoming calendar was reviewed. The Planning Secretary distributed draft copies of
motion worksheets. The Commissioners will review them and forward comments to the
secretary. The next meeting will be August 6th.

TIGARD 2027
City of Tigard Comprehensive Plan
The Tigard 2007 resource report establishes the factual basis that will be used,in conjunction
with the community issues and values, to develop Comprehensive Plan goals, policies, and
action measures. Below are the key findings from the Parks, Recreation, and Open Space
chapter of the document (which can be found in its entirety at www.tigard-or.gov/2027 ).
Please review the key findings as they will provide important background information when
discussing goals, policies, and action measures.
KEY FINDINGS
• The system of adding parks and related land and facilities in the City has kept up
with growth in the seven years since the Park System Master Plans adoption in 1999,
but has not achieved the Plan's aspirational standard.
• Many areas of the City are park deficient.
• The land supply available for parks and open space is becoming smaller and more
expensive.
• Given the current density in Tigard, sufficient land for neighborhood parks is
unavailable to meet the needs of underserved residential and non-residential areas.
• Many non-City-owned lands and facilities serve the park and leisure needs of Tigard •
residents.
• The City lacks a trail master plan to guide the development of the trail system and
facilitate progress toward its completion.
• The City has regulations in place that effectively provided for block links and
pedestrian connectivity in new neighborhoods. At the same time, the City has not
been proactive in addressing gaps in the off-street pedestrian system within older
neighborhoods.
• The SW Trails Group has identified a trail route within Northeast Tigard that
includes on and off street segments and inter-connects with the City of Portland-
1
• •
adopted SW Communities trail network. The group proposes that this route be
considered for adoption into the Tigard trail plan.
• In the past, the City has followed a de facto policy of not condemning land for trails.
This willing property approach has led to significant missing links in the trail system.
• The trail officially identified by Tigard as the "Powerline Trail" is a segment of a
larger inter-jurisdictional trail formally identified as the "Westside Trail" in the Metro
Regional Trails Map.
• The City does not operate a recreation program and is not served by a special park
and recreation district. In consequence of this, residents have limited opportunities
to participate in recreation programs. This deficiency includes ethno-specific
activities appealing to Tigard's growing minority populations.
• Overall, City parklands are well maintained. Maintenance problems identified in the
1999 Tigard Park System Master Plan have been, or are being, addressed.
• The new Park SDC methodology sets a per-project percentage limit on the use of
SDC funds. Some 63% of the cost of park improvements is assigned to non-SDC
funding sources. At this time, the City does not have a stable source of revenue that
can be used as the companion funding source for capital projects.
• Many of the projects identified in the Parks SDC parks capacity program are located
in the Bull Mt Urban Services Area.
• Tigard does not have a parks foundation. Such foundations provide local
governments with important additional programs to finance park and open space
projects.
• The City has been proactive in working with the Tigard Water District in regard to
the use of reservoir properties for open space. At the same time, the City has not
developed a partnership plan with the school district for the renovation and joint use
of school playgrounds to meet neighborhood park needs.
• Volunteers annually contribute thousands of hours to Tigard's park system and are a
non-monetary funding source for park maintenance and improvements.
• In recent years, the City has developed and employed innovative methods to create
more active park acreage to serve community needs. This has included making use of
a state infrastructure loan program to expand Cook Park and making certain types of
industrially zoned properties available for park uses.

TIGARD 2027
City of Tigard Comprehensive Plan
The Tigard 2007 resource report establishes the factual basis that will be used, in conjunction
with the community issues and values, to develop Comprehensive Plan goals, policies, and
action measures. Below are the key findings from the Environmental Quality chapter of the
document (which can be found in its entirety at www.tigard-or.gov/2027 ). Please review
the key findings as they will provide important background information when discussing
goals, policies, and action measures.
KEY FINDINGS—AIR RESOURCE QUALITY
• The air pollutants of greatest concern in Oregon are:
• Ground-level ozone, commonly known as smog
• Fine particulate matter (mostly from wood smoke, other combustion sources, cars
and dust)
• Hazardous air pollutants (also called Air Toxics)
• Carbon monoxide (mostly from motor vehicles)
• The City of Tigard is part of the Portland Area Airshed, which is currently in
compliance with the Clean Air Act requirements.
• DEQ has issued six active Air Contaminant Discharge Permits (ACDP) within the
City to regulate minor sources of contaminant emissions.
• Motor vehicles are now the primary source of air pollution in Oregon and the
number of miles driven daily by Tigard residents has increased 67% since 1990.
• Options available to the City for reducing vehicle miles traveled:
• Mixed-use zones that encourage working, living, and shopping in the same
neighborhood
• Land use patterns that provide alternative transportation opportunities
• Providing opportunities for increased density along public transit lines
• Developing a public transit system that is reliable,connected, and efficient
• Building a bicycle and pedestrian network that is connected, safe, and accessible
1
• •
• Connecting streets to provide additional travel options
• Options available for decreasing motor vehicle emissions include alternative
fuels/vehicles.
• The primary sources of household pollutants in Tigard include wood burning
fireplaces, and lawn and garden equipment.
• The City regulates noise and light pollution through Environmental Performance
Standards.
• The City can improve air quality for the community by continuing to participate in
alternative transportation programs and by purchasing alternative vehicles.
KEY FINDINGS—WATER RESOURCE QUALITY
• The Federal Clean Water Act regulates the release of pollutants into waterways
through the NPDES permit.
• Clean Water Services holds the NPDES permits for wastewater and stormwater in
the Tualatin River watershed and submits plans to Oregon DEQ outlining best
management practices.
• The City of Tigard implements the NPDES permits through and IGA with Clean
Water Services. The IGA outlines the functions the City must perform to ensure
compliance.
• Clean Water Services has a number of programs,including the Healthy Streams Plan,
which addresses non-point source pollution in the watershed.
• The City is devoted to improving water quality through the Sensitive Lands chapter
of the Community Development Code and the Citywide Sewer Extension Program.
• Water quality in the Tualatin River basin has been generally improving since the
1970s, despite continued urbanization in the watershed.
• DEQ has characterized Fanno Creek and the Tualatin River as having poor water
quality within the City of Tigard, and both will soon be added to the updated 303d
list for the Tualatin Basin.
• Point source pollution is predominately wastewater and stormwater discharge and is
easily monitored and measured.
• Non-point source is the largest source of water pollution in Oregon.
• Run-off from impervious surfaces,pet waste, and erosion are problematic non-point
sources.
• Stormwater management is important to improving water quality in the City of
Tigard and the City manages its system through the IGA with Clean Water Services.
2
• •
• The City maintains 79 water quality facilities that intend to remove pollutants and
detain stormwater to reduce channel erosion.
• Reducing impervious surfaces and using green street concepts can help improve
stormwater quality.
• Stream channel and riparian restoration activities can contribute to the reduction of
water pollution.
• The City has planted 30,000 native trees as part of stream restoration projects in the
past six years.
• The City has set a goal of planting 67,696 trees in the next five years.
• Trees outside of the riparian zone can help improve water quality through
interception and evapotranspiration.
• Proper wetland and floodplain function can remove pollutants from the surface
water system in the community.
KEY FINDINGS—LAND RESOURCE QUALITY
• The City is a member of the Metro wasteshed and the local plan is the Regional Solid
Waste Management Plan (RSWMP),which complies with DEQ requirements. The
plan provides a framework for coordinating solid waste programs within the region,
establishes direction for the system (reduction and recovery), and identifies roles and
responsibilities.
• The City is responsible for regulating and managing solid waste and recycling
collection services through franchise agreements with private haulers, and reviewing
collection rates and service standards.
• Clean Water Services (CWS) operates the Durham Wastewater Treatment Facility
within the city limits and is responsible for the collection and disposal of waste that
results from the treatment process.
• There are currently no solid waste or recycling debris collection or processing
facilities inside the city limits.
• Per capita generation of solid waste has increased annually by 3.2%over the last ten
years in the Metro region.
• The recycling of solid waste conserves limited natural resources and energy. The
recovery rate for residential recycling is close to targets set by the RSWMP, but
commercial recovery rates are well below the target.
3
• •
• Target areas that Metro has identified as having significant room for improvement
are the construction and business sectors,both of which have been regulated by
other jurisdictions to improve recovery rates.
• The DEQ regulates hazardous waste in Oregon and they administer permitting,
collection, disposal, and cleanup programs, as well as educational programs to reduce
risks associated with hazardous wastes.
• Household hazardous waste is not easily regulated and is an educational priority for
DEQ and Metro.
• Currently, there are no permanent hazardous waste collection, storage, or disposal
facilities within the city limits. All hazardous waste is transported outside of Tigard
for processing and disposal.
•
KEY FINDINGS—ENERGY CONSERVATION
• The Oregon Department of Energy (DOE) publishes a biennial report that provides
general information and quantitative data which can assist the City in making energy
related decisions.
• Transportation is the largest use of energy in the State at 38%. A considerable
reduction in energy use can be made with individuals altering their habits related to
the use of motor vehicles.
• The City has no energy generation or supply facilities and therefore the community's
energy supply and pricing is controlled by forces beyond its direct influence.
• Unstable energy pricing and supply will continue to affect communities as it did in
2002,when Oregonians spent 50% more per unit of energy to heat their homes than
in 1998.
• World oil production may peak in the next decade and begin a long-term decline.
Coupled with a growth in worldwide demand, peak oil will maintain or increase
already high oil prices.
• Natural gas supplies from North America are declining, while prices have doubled in
the past five years. Importing from overseas is an expensive option as it requires the
gas to be liquefied, transport tankers, and regasification plants. Worldwide
competition for the gas is also expected to increase.
• The DOE recommends conservation efforts for households, businesses, industry,
and transportation, as well as developing clean and renewable energy resources for
4
• •
insulation from and to reduce the community's vulnerability to volatile pricing and
supplies.
• A number of alternative fuel options exist for motor vehicles, but supplies and
availability are limited.
• Local jurisdictions have the ability to affect energy conservation efforts by reducing
automobile trips through developing efficient land use plans that promote compact,
mixed use communities.
• The City can lead by example by becoming more energy efficient as an organization
or challenge residents to reach energy conservation goals set by the community.
• Large energy uses which the City has control over include street lighting,water
transfer pumps, heating and cooling of municipal buildings, and the motor vehicle
pool.
• Solar-generated power and wood heating are the two most common options
available to the community for producing their own energy. Wood heating can be
problematic to air quality due to the release of fine particulate matter.
• The City currently provides some flexibility, with set-back adjustments and variances
during the land use planning process, that could take advantage of solar radiation.
• Weatherization, energy efficient building materials and appliances, and alternative
energy sources can all reduce energy consumption in buildings.
• The following land use planning strategies can result in a more energy-efficient
community:
• Establishing mixed-use zones to encourage working, living, and shopping in the
same neighborhood
• Providing opportunities for increased density along public transit lines
• Developing a public transit system that is reliable, connected, and efficient
• Building a bicycle and pedestrian network that is connected, safe, and accessible
• Connecting streets for efficiency and reducing congestion
• Re-use of vacant land and those uses which are not energy efficient

Process Recommendation
Three alternate ways to receive approval based upon the complexity of the
. development and the applicant's wishes:
1)Clear and objective track:Would emphasize quantifiable'clear and
objective'standards.Applicant's compliance could be determined by a
checklist. The decision would be made as a Type II decision by staff
and could be appealed to a review body:the Planning Commission,
Hearings Officer or a new'design review board.'
2)Discretionary track: 'Discretionary'standards use qualitative
statements,where there is more than one way for a designer to meet
the standard.Would result in a Type III decision with public hearing by a
review board (either an existing body-the Planning Commission or a
new body created for this purpose.)
3)The"over the counter"track would be used for applications for minor
changes and additions to existing development(up to a threshold to be
determined,but could be similar to the current code's'minor
modification'standards.)If applicant demonstrates that applicable
criteria were met,a decision would be issued within a short period of
. time in the form of a'compliance letter.'

MEMORANDUM
T I GARD
TO: City Center Advisory Commission and Planning Commission
FROM: Sean Farrelly,Associate Planner
RE: City Center Advisory Commission/Planning Commission Joint
Subcommittee Recommendations for Downtown Design Regulations
DATE: June 26, 2007
A joint subcommittee of the City Center Advisory Commission and the Planning
Commission was formed in April,2007 to recommend a format and level of design
regulation appropriate to the Downtown Urban Renewal District. In addition to meeting
several times, two members of the subcommittee also attended an all-day training session on
Form-based Codes organized by the Oregon chapter of the American Planning Association.
The following details the subcommittee's proposals.
The joint subcommittee has recommended the development and adoption of a"hybrid"
code: one that incorporates a Form-Based Code approach toward building form, but uses
provisions,processes and standards of the existing development code. This recommendation
was made after reviewing and deliberating over different examples of codes that regulate
design. The members came to consensus that the following criteria should be and are
addressed by a "hybrid" code:
• Be flexible,but require high quality design.
• Employ greater use of graphics to explain community goals and desired urban form
to applicants,neighborhood groups and administrators.
• Illustrate development standards and expected building forms with plans, sections,
illustrations, and multiple photo examples.
• Consider the building"walls" that frame the Right of Way (the "public realm") as
the primary determinant of form.
• Take development feasibility and economics into account.
• Coordinate building and street design.
• Provide predictability for urban form.
• More gradual form transition (tapering of building height,bulk, and massing)
between adjacent areas with different development intensities.
• Address green spaces and character.
• Require new development to be designed by a registered architect.
• Facilitate the transition of uses over time.
• Innovative nonconforming development and use regulations (new work on
nonconforming structures must move toward conformance). Employ incentives
• •
such as facade improvement grants,ombudsman (staff person) who can
provide technical assistance and/or create "deals" to encourage existing
development to conform to new regulations.
Process
The subcommittee recommended that the design regulations for the Downtown follow a
system with three alternate ways to receive approval based upon the complexity of the
development and the applicant's wishes:
1) Clear and objective track: This track would emphasize quantifiable "clear and objective"
standards. For example, a "clear and objective" standard for a facade is:
`For buildings facing public street right-of way, design and construct ground floor facades with at
least 65 percent window area. Such windows shall not be mirrored or treated in such a way as to
block views into the building."
The applicant's compliance could be determined by a checklist. The decision would be
made as a Type II decision by staff and could be appealed to a review body: the Planning
Commission,Hearings Officer or a new"design review board."
As part of the subcommittee discussions,a legal opinion was obtained from the City
Attorney regarding the legality of form based codes and illustrated regulations. It was his
opinion that illustrations or diagrams demonstrating the desired form of development
would be considered clear and objective standards under Oregon law.
2) Discretionary track: "Discretionary" standards use qualitative statements,where
there is more than one way for a designer to meet the standard. An example of a
discretionary standard is: `Provide views into shops and offices for ground floor facades
along the public sidewalk."
This track would result in a Type III decision with public hearing by a review board
(either an existing body- the Planning Commission or a new body created for this
purpose.) In exchange for more flexibility,there is more scrutiny by review board and the
public process. The process must result in a timely decision.
3) The "over the counter" track would be used for applications for minor changes and
additions to existing development (up to a threshold to be determined,but could be
similar to the current code's "minor modification" standards.) If the applicant
demonstrates that applicable criteria were met, a decision would be issued within a short
periods of time (perhaps a week),in the form of a"compliance letter."
Such a three-track system would demonstrate flexibility,in that it would allow projects that
did not meet the objective standards to have an alternative way to gain approval.
Next Steps
The members of the subcommittee will take these recommendations to their respective
bodies- the CCAC and Planning Commission for comment. On August 14, these
recommendations and any Planning Commission and CCAC comment will be presented to
the City Council. Council will also be asked to provide its input. Following this staff will
develop a timeline and process to work on Phase II,including public input, developing the
code language and graphics.

Jerree Lewis -Environment Goals for City of Tigard
From: "Matthew J. Muldoon" <muldoonent2 @comcast.net>
To: "'Darren Wyss' <Darren @tigard-or.gov>
Date: 7/14/2007 9:28:41 AM
Subject: Environment Goals for City of Tigard
CC: <JERREE @tigard-or.gov>
There is an increased need to distinguish practices which actually reduce environmental impact vs. marketing
efforts. Business schools now advise all marketing professionals to make environmental claims. Where
environmental benchmarks are lax, any environmental statement is as good as any other. For example one may
claim the use of recycled materials when those materials may do long term environmental harm and be extremely
difficult to dispose of in the future. One may also claim the use of local materials when objective environmental
impact(energy use, inclusive of transport @ pollution: hear, air, water quality impact) is negative using local
materials. All impact is not equal. Yet without targets and understanding of what is just routine business as usual
with some green marketing applied, there is a high chance that Tigard will reward form rather than true
environmental impact. I would like to share this concern and should time allow Monday night hear how Tigard
intends to distinguish between building methods which meet specific tangible goals vs. general obligatory green
marketing.
1: Need to identify Environmental Goals:
History: Prior to 1993 most federal government documents had a general statement re: positive environmental
impact
Concern: We seem to be moving in same direction again, rewarding statements without quantifiable
standards or benchmarks.
Tokyo and NY City have tried to address this"Green Trap"with recognition of the following among other goals:
Goals: Capture of rainwater to be used for plant watering, etc reducing demand on city water systems.
Reduction of power consumption against building class benchmarks through use of innovative
materials and more efficient systems
Ex of rewarded methods: 3M films that redirect light horizontally, more efficient heating and
cooling systems against benchmarks, etc.
Generation of power used on premises using compact wind turbines, solar panels, natural
convection, etc. (meeting noise standards)
Filtering of air, releasing scrubbed air post use improving ambient city air quality
Important Note: These measures against building class benchmarks permit formal city recognition of true
positive environmental impact.
In all cases functional standards must still be met. The difference is real environmental impact
through improved benchmarks.
Potential Impact for City of Tigard, Discretionary Density Allowance and higher chance of approval before
Planning Commission for projects which exceed
quantifiable benchmarks for building classes.
2: The need to define all environmental terms in a City of Tigard document to be incorporated by reference in
other City of Tigard code and documents.
Impact: Terms then have specific meaning for Planning Commission, Taxation, and other purposes.
Sustainability and Green then have specific meaning.
Failure to Create this Document: Persons can pick and chose between conflicting standards. City incurs
significant legal liability and work duplication.
Moreover tax code will become muddled when City of Tigard seeks to reward specific practices which
improve environmental footprint.
Considering that the only businesses that will fail to make green statements are those without marketing
departments, Tigard must consider what its environmental goals really are. Then marketing can be largely
ignored and actual desired effects can be compared to prevailing benchmarks to clearly see if there are superior
methods, materials or practices utilized in new construction. Thank you for considering these concerns.
Best Wishes,

MEMORANDUM
TIGARD 2027
TO: Planning Commission
FROM: Darren Wyss, Associate Planner
RE: Environmental Quality and Parks, Recreation, and Open Space
Comprehensive Plan Work Session
DATE: July 9, 2007
At the July 16`h Planning Commission meeting, staff will present the draft goals, policies, and action
measures for the Environmental Quality and Parks, Recreation, and Open Space topics for Planning
Commission review, discussion, and editing. The draft goals, policies, and action measures were
created based on a number of activities and include:
• Tigard Beyond Tomorrow Visioning Process
• Community surveys over the past several years
• Tigard 2007 Resource Report
• Citizen review of draft goals at two Comprehensive Plan open houses
• Citizen input at Policy Interest Team meetings
These draft goals, policies, and action measures are intended to reflect the community's values and
aspirations for land use planning. They also aim to organize and coordinate the relationships
between people, land, resources, and facilities to meet the current and future needs of Tigard.
This meeting gives the Planning Commission the opportunity to ask questions of staff on the
concepts or content of the language that is included in the draft goals, policies, and action measures.
This is also the appropriate time to evaluate the citizen input versus the views of the Commission on
what it ultimately recommends to City Council. The intended outcome of the meeting would be a
consensus on the final draft goals, policies, and action measures that will be brought before the
Planning Commission for a public hearing on August 20t. To meet this timeline, a thorough review
of the materials before the meeting,with questions ready,will help to ensure a focused review and
discussion that is efficient. If unable to finish the review during the July 16th meeting, it will
continue to the August 6th meeting.
Remember, staff is available to answer any questions that you may have leading up to the meeting
and we encourage you to call or email. Getting all questions answered and the appropriate
information to help with the discussion will eliminate the need to schedule additional meetings
throughout the process of updating the Comprehensive Plan.

For questions on Environmental Quality, contact Darren Wyss at 503-718-2442 or
darren @tigard-or.gov
The attached material for each of the topics includes:
• Draft goals, policies, and action measures
• "Building blocks" based on the Tigard 2007 Resource Report,visioning process, and surveys
that were used with the Policy Interest Teams to provide them with a structure to help
develop draft policies. Additions/comments from citizens are included as underlined text,
while deletions contain a strikethrough
• Key findings from the Tigard 2007 Resource Report
• Community Issues/Values gleaned from the visioning process and community surveys
• Text from the current Comprehensive Plan to be deleted when the new goals, policies, and
action measures are adopted by City Council
Included below are some definitions that may be helpful to your review:
Goal
Definition -A general statement indicating a desired end or the direction the City will follow to
achieve that end.
Obligation -The City cannot take action which violates a goal statement unless:
1. Action is being taken which clearly supports another goal.
2. There are findings indicating the goal being supported takes precedence (in the particular case)
over another.
Policy
Definition -A statement identifying Tigard's position and a definitive course of action. Policies are
more specific than goals. They often identify the City's position in regard to implementing goals.
However, they are not the only actions the City can take to accomplish goals.
Obligation -The City must follow relevant policy statements when amending the Comprehensive
Plan, or developing other plans or ordinances which affect land use such as public facility plans, and
zoning and development standards or show cause why the Comprehensive Plan should be amended
consistent with the Statewide Land Use Goals. Such an amendment must take place following
prescribed procedures prior to taking an action that would otherwise violate a Plan policy. However,
in the instance where specific plan policies appear to be conflicting, the City shall seek solutions
which maximize each applicable policy objective within the overall context of the Comprehensive
Plan and Statewide Goals. As part of this balancing and weighing process, the City shall consider
whether the policy contains mandatory language (e.g., shall,require) or more discretionary language
(e.g., may, encourage).

• •
Recommended Action Measures
Definition -A statement which outlines a specific City project or standard which, if executed,would
implement goals and policies. Recommended action measures also refer to specific projects,
standards, or courses of action the City desires other jurisdictions to take in regard to specific issues.
These statements also define the relationship the City desires to have with other jurisdictions and
agencies in implementing Comprehensive Plan goals and policies.
Obligation - Completion of projects, adoption of standards, or the creation of certain relationships
or agreements with other jurisdictions and agencies,will depend on a number of factors such as
citizen priorities, finances, staff availability, etc.
The City should periodically review and prioritize recommended action measures based on current
circumstances, community needs and the City's goal and policy obligations. These statements are
suggestions to future City decision-makers as ways to implement the goals and policies. The listing
of recommended action measures in the plan does not obligate the City to accomplish them. Neither
do recommended action measures impose obligations on applicants who request amendments or
changes to the Comprehensive Plan. The list of recommended action measures is not exclusive. It
may be added to, or amended, as conditions warrant.
Effective Impervious Area
Impervious area such as rooftops, streets, sidewalks, and parking areas do not allow water to drain
into the soil. Impervious area that collects and drains the water directly to a stream or wetland
system via pipes or sheet flow is considered "effective impervious area", because it effectively drains
the landscape. Impervious area that drains to landscaping, swales, parks and other impervious areas
is considered "ineffective" because the water is allowed to infiltrate through the soil and into ground
water,without a direct connection to the stream or wetland.
