President Tepedino called the meeting to order at 7:35 P.M. The meeting was held at Fowler Junior High School - Lecture Room, 10865 S.W. Walnut Street, Tigard, Oregon. 2. ROLL CALL: Present: President Tepedino; Commissioners Clifford Speaker, Don Moen, Bonnie Owens, and Roy Bonn. Excused absence: Phil Edin, Mark Christen, Deane Leverett and Richard Helmer. STAFF: William Monahan, Director of Planning and Development; Jeremy Coursolle, Associate Planner; and Diane Jelderks, Clerk Typist. 3. The minutes from November 9, 1982 were considered. President Tepedino stated that minor corrections had been made to staff prior to the meeting. Commissioner Owens noted that on page 4, second paragraph that she was concerned that the number of units per acre was correct not the size of the lot. Commissioner Donn moved and Commissioner Moen seconded to approved minutes as corrected and amended. The motion carried unanimously by members of the Commission present. 4. COMMISSION COMMUNICATION o NPO #3 submitted a memorandum regarding the Energy Element of the Comprehensive Plan. 5. PUBLIC HEARINGS 41 President Tepedino opened the Public Hearing by reading the usual statement of authority for the procedure to be followed in the meeting. • President Tepedino wanted to publicly congratulate Bonnie Owens as he had heard a number of comments on how well she had handled the CCI meeting in his absence. She has been doing a fine job for the City, Planning Commission and staff. • President Tepedino provided his personal thought from his perspective as Chairman of the Planning Commission. He emphasized the urgency of the timing of this effort. There is a lot of pressure both externally and internally. We have a responsibility to the growth of the City with the planning that is being done. We have the responsibility as Planning Commissioners to the City, the public, ourselves and the NPO's. The NPO's will gain from a Comprehensive Plan. For too many years we've been fighting the difficulty of the various Neighborhood Planning Organizations diverting from what was the main thrust of the plan or disagreeing with Neighborhood Plans on the other side of the street. • He feels it is necessary to adopt a Comprehensive Plan at this time. He also wanted to emphasize that life is a compromise and those who will not compromise are like trees which refuse to bend in the wind, and we all will suffer from those who refuse to compromise. The staff is doing its utmost to provide the 'NPO's, the CCI, Planning Commission and City Council with the best information they have been able to develop. However, he would submit today that the Comprehensive Plan will not be perfect. He would suggest that we take a long range, philosophical view, and try to get something in place, because the right to amend is theirs, the NPO's, CCI and City Council, to modify and correct as needed. In his estimation it would be worse to leave the City without a plan than to have a plan that is not totally adequate. He felt to drop the ball now would be a terrible disservice to the City of Tigard. 5.1 COMPREHENSIVE PLAN: ENERGY Jeremy Coursolle, Associate Planner explained how this is the second element of the Comprehensive Plan. The first element, Citizen Involvement, was adopted by the City Council, November 22, 1982. The second element deals with energy and conservation, the City's role and the energy sources that are economically feasible to any structure within the City of Tigard. (Staff has attempted to set some direction rather than placing mandates.) That way when information is available to us, the economy turns around, and interest is there within the community, we then will start looking at some means to help to conserve the energy that we do have. The NPO's have all had an opportunity to look at this document. Unfortunately, the CCI did not reach a total consensus. Staff has requested that each NPO chairperson have comments submitted prior to the public hearing. Mr. Coursolle, reminded the Commission that this is a legislative hearing requiring a recommendation from the Planning Commission to the City Council. Staff is proposing one change, adding policy 9.1.3. THE CITY SHALL ENCOURAGE LAND USE DEVELOPMENT WHICH EMPHASIZES SOUND ENERGY CONSERVATION, DESIGN AND CONSTRUCTION. (This was a suggestion from a member in NPO #4.) Associate Planner Coursolle reviewed the energy document which includes Energy Conservation and Local Governments' Role, Alternative Energy Sources, Findings, Policies and Implementation Strategies. • The document was reviewed page by page with staff and Planning Commissioners making changes and corrections as necessary. • NPO #3's submission was read into the record by Associate Planner Coursolle. Discussion followed between Commissioners and staff as to the intent of this recommendation. • Associate Planner Coursolle explained locational criteria. He stated , that established and developing areas should be compatible and that locational criteria would insure this would happen. PAGE 2 - PLANNING COMMISSION MINUTES - NOVEMBER 23, 1982 • Commissioner Speaker suggested that instead of replacing strategy #3 with the NPO #3 recommendation that instead it should be added as number 4 under implementation strategies, then renumber the following strategies. • President Tepedino suggested that this might be folded into Implementation Strategy number eight. Commissioner Speaker did not feel this would be appropriate. Further discussion followed. • Commissioner Moen felt it was inappropriate to either stick it in or tear it apart and put it in here and there. He was not sure what the intent of NPO #3 was. Commissioner Speaker was not sure it mattered what the intent was, only that in the future the document would be read and followed. • It was determined to add NPO #3 recommendation as follows: 9. Locational criteria shall be established to minimize travel in order to conserve energy. PUBLIC TESTIMONY - No one appeared to speak CROSS EXAMINATION AND REBUTTAL - No one appeared to speak COMMISSION DISCUSSION AND ACTION • Commissioner Owens moved and Commissioner Speaker seconded to forward the Energy Document to the City Council with corrections and amendments with recommendation of approval. The motion carried by unanimous vote of Commissioners present. 6. OTHER BUSINESS General Information on Comprehensive Plan • Director of Planning explained that staff had reserved the school facilities for December 7 through December 11th for public hearings on the Comprehensive Plan. • Discussion followed between Staff and Commissioners regarding the time schedule. It was decided that the Commission would hold public hearings on Tuesday, December 7 at 7:30 P.M.; Thursday, December 9 at 7:30 P.M.; and Saturday, December 11, starting at 1:30 P.M. , if necessary. • Commissioner Owens suggested Commissioner Speaker be responsible for all typo-errors to minimize time. • President Tepedino asked if the NPO's and CCI had received all the documents. Staff stated that the Transportation document was to be completed and distributed by Tuesday, November 30th. All other documents have been available and will be provided to the NPO's by that date. PAGE 3 - PLANNING COMMISSION MINUTES - NOVEMBER 23, 1982 • Commissioner Bonn questioned the status of the floodplain issue. Director of Planning and Development Monahan stated the City Council had decided to wait until after the first of the year to deal with the apparent discrepancy and clean up the code. • Commissioner Owens reported on the results of the CCI meeting which she had been presiding over. She stated the committee had come a long way from the first meeting. There had been a lot of hostility and not much working together. The full number of potential members has not always been present. First the documents are reviewed by the NPO groups then the Chairperson would bring their suggestions to the CCI meeting. The Energy and, the Citizen Involvement document were dealt with quite easily. They are presently working on the Findings, Policies and Implementation Strategies. NPO #3 has rewritten a portion of the Housing document and brought it to the CCI. • Associate Planner Coursolle stated that the Housing document was the first document distributed and was prepared prior to involvement of the Word Processing Staff. He also requested each NPO submit written comments so they could provide the Planning Commission with input. He is now in the process of reviewing and responding to these comments. • Commissioner Owens continued that everyone is under a time pressure. They are continually hearing that there is not enough time to accomplish everything, especially from one person. There has been a tremendous amount of effort and energy from Bill and Jeremy providing teem with information while also accepting all the input from the NPO's. At times it seemed the input was grinding the wheels to a halt. She felt the committee had come a long ways but she was still concerned about keeping the meeting going especially when they deal with the Housing and Transportation elements. • President Tepedino questioned if NPO #7 is still active. Associate Planner Coursolle stated the NPO #7 has been meeting, however they have not had a consistent membership. They only have six people on their NPO, but they do not appear consistently. They are committed to the task. 7. Meeting Adjourned 9:05 P.M. _ I / e ane J1er s, Secreta y ii S . li1 744111k Nit elk 41111116 1 v . 1 .

In addition, it recommends findings, policies and implementation strategies to meet the Goal #13 requirements. The Statewide Planning Goal #13 reads: To conserve energy. Land and uses developed on the land shall be managed and controlled so as to maximize the conservation of all forms of energy, based upon sound economic principles." Since the oil embargoes of the, 1970's, traditionally cheap and unlimited petroleum energy sources have become .a thing of the past. This has caused all levels of government, the private sector as well as individual households to closely scrutinize energy usage and cost. The rapidly changing energy situation is one of the foremost problem of our time Energy prices and supplies have been directly related to inflation, interest rates, and economic growth. Due to the past development of our cities as high and inefficient energy users, local governments and communities are becoming more involved in energy managment. For example, the City of Portland instituted a mandatory weatherization program requiring residents to meet insulation standards at the time of resale or within five years. ENERGY CONSERVATION AND LOCAL GOVERNMENTS' ROLE The energy crisis and the adoption of the LCDC Goal and Guidelines #13: Energy Conservation, have provided the impetus for local governments in Oregon to seriously consider their role and the opportunities available to them to influence a reduction in local energy usage. Local government can influence energy conservation by two basic strategies: 1. Adoption of an energy efficient land use pattern which reduces the consumption of non-renewable energy; for example by: a. Stemming urban sprawl; b. Ensuring that developments occur in a fashion which supports public transit, bicycle and other alternative modes of transportation; c. Allowing higher densities and mixed uses in appropriate areas of the community. 2. Through the adoption of ordinances which provide for energy or or the use of alternative energy sources; for example b y: CeM�ru.ra a. Requiring mandatory weatherization of all structures, particularly residential; and Page 3 b. Adopting development standards which require the consideration of solar design in any new development; c. Adopting solar access ordinances; and d. Providing information to the general public concerning the methods and monetary benefits of alternative energy sources. The role of local government can differ according to the type of strategy being considered. On the supply side, or the development of alternative resources, the local government's role is primarily permissive, allowing for the experimentation and application of alternative energy sources. State and federal government agencies have a more active role in increasing energy supplies through tax incentives and basic research. However, it should be the responsibility of the local jurisdiction to keep abreast of state and federal programs and possible avenues for their assistance in local energy matters. In addition, the local government is often given the opportunity to play a more affirmative role regarding the reduction of consumption of energy, e.g. , Portland's Weatherization Program. In the Portland Metropolitan Area, transportation and residential uses together account for 50% of the energy consumption. Automobile use accounts for 75% of all transportation energy, while mass transit uses. only 1%. used for heating residential energy is use �y. g Approximately 70X of all reside gy '�sl (Source: Portland Bureau of Planning, 1977). Energy usage is illustrated in Figure I and II. The events of the 1970's have underlined the reality of a fluxuating energy supply and continually rising energy costs. As an attractive place to live and work, the Portland Metropolitan Area will be adversely affected. This effect can be reduced through the application of conservation measures. According to the "Portland Energy Conservation Project" study, the Metropolitan Area could save as much as 34% of its projected energy usage in the mid-1990s with conservation programs. This possible savings is illustrated in Figure III. ALTERNATIVE ENERGY SOURCES Currently, the City of Tigard has not developed energy sources. All of the City's energy supplies come from sources outside the City and from traditional sources, including gas, oil and electricity. However, there are numerous energy alternatives that can come from within the City. The problem with suggesting a list of alternatives is that it is often difficult to distinguish between those alternatives which have been proven cost effective by research and practical application, and those ideas which are conceptual in nature and require extensive engineering and economic feasibility studies to determine their applicability to Tigard. The following is an identification of those alternatives which may be readily applicable to all structures in the City with a brief explanation of their merits. Wood An energy source that is already widely used in the Tigard area is wood. The proper use of wood in conjunction with an efficient woodburning stove can be a viable substitute to space heating rather than traditional energy sources.

The Oregon State Department of Environmental Quality (DEQ) airshed studies have identified wood heating as a significant source of uncontrolled pollutants and a major cause of violations of the state and federal ambient air quality standards in the Portland Metropolitan Area. Major metropolitan areas as well as a growing number of smaller cities are experiencing pronounced degradation of wintertime air quality, including low lying visibility impairment, soiling and odor problems. Certain airsheds are more susceptible to wood smoke impacts than others, depending on local topography and meteorological conditions. Currently, more than 50% of Oregon's households use wood for some space heating. Heating with wood is expected to continue as more and more individuals try to offset accelerating home heating costs of conventional sources of heat. Unfortunately, a wood stove can emit 224 times more particulate than an oil furnace and up to 457 times more than natural gas for the same heat value. (Source: DEQ, 1981 Air Quality Annual Report) The growing concern over air quality with the increasing use of wood can be somewhat mitigated by the public becoming more educated on the proper and least polluting means. Solar The potential use of solar as an energy source will be directly dependent upon the community's willingness to protect solar access for the life of a structure. Passive and active solar systems to augment space and water heating have had substantial merit, especially in new constructions. Except for the most obvious constraint, lack of access to the sun, many existing buildings also readily lend themselves to retrofitting and remodeling activities which would allow them to take advantage of solar radiation. Since solar is becoming much more cost effective, is environmentally benign, is reliable and is one of the few significant energy resources that can be implemented by individuals and businesses, it's expected that solar energy usage will grow in popularity. The use of solar energy falls into two very broad categories, active and passive. In very simple terms, active solar can be defined as any system which uses mechanical equipment to take advantage of the energy from the sun. Recent advancements in the design and manufacturing of active solar systems have resulted in systems being available which, when installed properly, can have an operating life of 20 to 30 years. Passive solar systems rely totally upon the siting and design of a building to extract benefit from the sun's energy without the assistance of any mechanical equipment. Passive solar techniques were used by the oldest civilizations, and the principles of solar design have remained virtually unchanged. It has only been recently that these same principles have been accepted and made marketable in the construction of contemporary buildings. Most reliable sources state that a combination of active and passive solar systems have the potential to "economically provide 50-80 percent of the heating, cooling and hot water needs of many homes in Tigard." Mi Page 7 There are many areas within the community where both passive and active systems could be used; but the availability of solar access cannot occur by happenstance. If the community desires to make solar a viable energy source, then regulatory measures which ensure rooftop, south wall, and south lot line solar access must be adopted. Wind* A growing body of research indicates that the State of Oregon has considerable wind power potential. Development of this resource over the next two decades could provide a significant portion of needed electric energy, about 10% of peak demand according to the latest forecast. Private and public utilities are developing commercial-scale wind power farms' (or arrays of wind power generators); the technology is available and the costs are favorable. Authorities in the field expect wind power, given present trends, will begin by the mid-1980s to be extensively developed as a cost-effective, conventional source of electricity.

To maintain the same power density, speed increases 5%/5000 feet (3%/100m) of elevation (m/s = meters per second). An average wind speed of 12.0 miles per hour or greater is required to make a good potential wind power site. This corresponds to a wind power class of 3 or more. Washington County possesses areas having that wind power class. * Source: Washington County Comprehensive Resource Document, 1981. Page 8 The full potential for wind generation in the City cannot be generally determined. Each geographic location would have to be individually reviewed. Small-scale wind power development - for residences, farms and small commercial applications is not expected to provide a significant amount of electricity by comparison with utility and heavy industry use By the year 2000 it will reduce only 7% of the capacity expected in 1985 for the larger-scale wind power developments in Oregon. The wind power potential of Oregon, and presumably the Washington County area also, will be developed for the most part through large wind turbine "farms." Large-scale wind power farms will not have major environmental impacts except those related to timber production. One researcher with the U.S. Bureau of Reclamation concluded: "Environmental impacts of large windfarms are mild and easily mitigated in comparison with those of conventional energy alternatives." Such utility-scale farms are expected to require between 0.41 acre and 3.66 acres of land. Wind turbine generators can interfere with television signals, but this is not a major problem. Interference can arise with the receiving antenna within . three miles (UHF) or one-fourth mile (VHF) of the rotating blades. The effect is reduced by directional antenna, local television repeaters, circularly polarized transmissions, or cable reception. In remote areas where wind power farms are likely to locate, the population is sparse and residents typically use directional antennas or have cable television; therefore the problems of interference in UHF televisions reception are minimal. The task force on wind of the Oregon Alternate Energy Development Commission found little reason to be concerned about low frequency noise from wind power generators. Calculations and field observations show insignificant noise levels from most large wind turbines. The aesthetic impact of wind power farms on the landscape should also be insignificant in Washington County areas. Wide spacing of each individual generator lessens the appearance of domination in an area. One nation-wide attitude opinion survey, in which respondents assumed much closer spacing, showed a definite aesthetic preference for wind turbines over power transmission towers and lines. At present there is no absolute right to wind access in Oregon. As with solar energy access, the lack of such legal rights reflects an absence of interest in the past. Treatment of this question of wind access may be required at both the local and state level. For example, it is possible to create a local wind access permit system to define the legal wind access of a property owner and thereby prohibit owners of adjacent land from conflicting uses. Given the general locat ion of the wind power resource in Washington on Count Y areas, it seems unlikely that the absence of wind access legal definitions would impede the location of wind power farms although the larger. "farms" may not be appropriate uses in Tigard. For residential or small-scale uses elsewhere, such legal definitions would be more important. r. Page 9 The Accessory Development section of the Tigard Community Development Code should address the usage and location of Wind Generation Energy Devices (WGED). FINDINGS o Transporation and residential uses account for approximately 'half of the . total energy consumption in the Portland Metropolitan Area Industrial and commercial uses comprise the other half of energy consumption. , o The City 'V no developed energy sources. o Conservation of energy at the local level is best achieved through programs aimed at energy efficient transporation modes and land use patterns, reducing travel distances between residential and work areas, infilling vacant land, increasing densities of land uses as a whole and encouraging alternative energy uses. o All forms of nonrenewable energy sources used today are finite and the cost of these sources have increased as the supply has decreased. o A reduction in the community-wide use of nonrenewable energy sources and the development of renewable energy resources would have beneficial impacts on both local and national economy. o Mass transit systems can have a positive influence upon energy consumption y but require higher density corridors and activity areas to be effective. o The availability of cheap energy in the past has resulted in the construction of residential and commercial buildings that are energy inefficient. Weatherization and insulation of existing and new structures would substantially reduce energy consumption for heating and cooling these structures. o Although it is a widely used substitute for traditional energy sources, woodburning stoves can have adverse affects on air quality if improperly used. J o Alternative architecture and site design considerations can affect energy consumption; such as structure orientation to the sun, landscaping, topography and adjacent structures. o Small scale wind generating devices may be a viable alternative energy source for Tigard residences. o The private automobile consumes about 75% of all petroleum used in transporation in the Portland Area.

President Tepedino called the meeting to order at 7:35 P.M. The meeting was held at Fowler Jurior High School - Lecture Room, 10865 S.W. Walnut Street, Tigard, Oregon. 2. ROLL CALL: Present: President Tepedino; Commissioners Clifford Speaker, Don Moen, Bonnie Owens, and Roy Bonn. Excused absence: Phil Edin, Mark Christen, Deane Leverett and Richard Helmer. STAFF: William Monahan, Director of Planning and Development; Jeremy Coursolle, Associate Planner; and Diane Jelderks, Clerk Typist. 3. The minutes from November 9, 1982 were considered. President Tepedino stated that minor corrections had been made to staff prior to the meeting. Commissioner Owens noted that on page 4, second paragraph that she was concerned that the number of units per acre was correct not the size of the lot. Commissioner Bonn moved and Commissioner Moen seconded to approved minutes as corrected and amended. The motion carried unanimously by members of the Commission present. 4. COMMISSION COMMUNICATION o NPO #3 submitted a memorandum regarding the Energy Element of the Comprehensive Plan. 5. PUBLIC HEARINGS e President Tepedino opened the Public Hearing by reading the usual statement of authority for the procedure to be followed in the meeting. • President Tepedino wanted to publicly congratulate Bonnie Owens as he had heard a number of comments on how well she had handled the CCI meeting in his absence. She has been doing a fine job .for the City, Planning Commission and staff. • President Tepedino provided his personal thought from his perspective as Chairman of the Planning Commission. He emphasized the urgency of the timing of this effort. There is a lot of pressure both externally and internally. We have a responsibility to the growth of the City with the planning that is being done. We have the responsibility as Planning Commissioners to the City, the public, ourselves and the NPO's. The NPO's will gain from a Comprehensive Plan. For too many years we've been fighting the difficulty of the various Neighborhood Planning Organizations diverting from what was the main thrust of the plan or disagreeing with Neighborhood Plans on the other side of the street. 4110 1110 He feels it is necessary to adopt a Comprehensive Plan at this time. He also wanted to emphasize that life is a compromise and those who will not compromise are like trees which refuse to bend in the wind, and we all will suffer from those who refuse to compromise. The staff is doing its utmost to provide the 'NPO's, the CCI, Planning Commission and City Council with the best information they have been able to develop. However, he would submit today that the Comprehensive Plan will not be perfect. He would suggest that we take a long range, philosophical view, and try to get something in place, because the 10 right to amend is theirs, the NPO's, CCI and City Council, to modify and correct as needed. In his estimation it would be worse to leave the City without a plan than to have a plan that is not totally adequate. He felt to drop the ball now would be a terrible disservice to the City of Tigard. 5.1 COMPREHENSIVE PLAN: ENERGY Jeremy Coursolle, Associate Planner explained how this is the second element of the Comprehensive Plan. The first element, Citizen Involvement, was adopted by the City Council, November 22, 1982. The second element deals with energy and conservation, the City's role and the energy sources that are economically feasible to any structure within the City of Tigard. (Staff has attempted to set some direction rather than placing mandates.) That way when information is available to us, the economy turns around, and interest is there within the community, we then will start looking at some means to help to conserve the energy that we do have. The NPO's have all had an opportunity to look at this document. Unfortunately, the CCI did not reach a total consensus. Staff has requested that each NPO chairperson have comments submitted prior to the public hearing. Mr. Coursolle, reminded the Commission that this is a legislative hearing requiring a recommendation from the Planning Commission to the City Council. Staff is proposing one change, adding policy 9.1.3. THE CITY SHALL ENCOURAGE LAND USE DEVELOPMENT WHICH EMPHASIZES SOUND ENERGY CONSERVATION, DESIGN AND CONSTRUCTION. (This was a suggestion from a member in NPO #4.) Associate Planner Coursolle reviewed the energy document which includes Energy Conservation and Local Governments' Role, Alternative Energy Sources, Findings, Policies and Implementation Strategies. • The document was reviewed page by page with staff and Planning Commissioners making changes and corrections as necessary. • NPO #3's submission was read into the record by Associate Planner • Coursolle. Discussion followed between Commissioners and staff as to the intent of this recommendation. o Associate Planner Coursolle explained locational criteria. He stated that established and developing areas should be compatible and that locational criteria would insure this would happen. PAGE 2 - PLANNING COMMISSION MINUTES - NOVEMBER 23, 1982 III/ 4110 • Commissioner Speaker suggested that instead of replacing strategy #3 with the NPO #3 recommendation that instead it should be added as number 4 under implementation strategies, then renumber the following strategies. • President Tepedino suggested that this might be folded into Implementation Strategy number eight. Commissioner Speaker did not feel this would be appropriate. Further discussion followed. •`, Commissioner Moen felt it was inappropriate to either stick it in or tear it apart and put it in here and there. He was not sure what the intent of NPO #3 was. Commissioner Speaker was not sure it mattered what the intent was, only that in the future the document would be read and followed. • It was determined to add NPO #3 recommendation as follows: 9. Locational criteria shall be established to minimize travel in order to conserve energy. PUBLIC TESTIMONY - No one appeared to speak CROSS EXAMINATION AND REBUTTAL - No one appeared to speak COMMISSION DISCUSSION AND ACTION • Commissioner Owens moved and Commissioner Speaker seconded to forward the Energy Document to the City Council with corrections and amendments with recommendation of approvl. The motion carried by unanimous vote of Commissioners present. 6. OTHER BUSINESS General Information on Comprehensive Plan • Director of Planning explained that staff had reserved the school facilities for December 7 through December 11th for public hearings on the Comprehensive Plan. • Discussion followed between Staff and Commissioners regarding the time schedule. It was decided that the Commission would hold public hearings on Tuesday, December 7 at 7:30 P.M. ; Thursday, December 9 at 7:30 P.M.; and Saturday, December 11, starting at 1:30 P.M. , if necessary. • Commissioner Owens suggested Commissioner Speaker be responsible for all typo-errors to minimize time. • President Tepedino asked if the NPO's and CCI had received all the documents. Staff stated that the Transportation document was to be completed and distributed by Tuesday, November 30th. All other documents have been available and will be provided to the NPO's by that date. PAGE 3 - PLANNING COMMISSION MINUTES - NOVEMBER 23, 1982 4110 4110 • Commissioner Bonn questioned the status of the floodplain issue. Director of Planning and Development Monahan stated the City Council had decided to wait until after the first of the year to deal with the apparent discrepancy and clean up the code. • Commissioner Owens reported on the results of the CCI meeting which she had been presiding over. She stated the committee had come a long way from the first meeting. There had been a lot of hostility and not much working together. The full number of potential members has not always been present. First the documents are reviewed by the NPO groups then the Chairperson would bring their suggestions to the CCI meeting. The Energy and the Citizen Involvement document were dealt with quite easily. They are presently working on the Findings, Policies and Implementation Strategies. NPO #3 has rewritten a portion of the Housing document and brought it to the CCI. o • Associate Planner Coursolle stated that the Housing document was the first document distributed and was prepared prior to involvement of the Word Processing Staff. He also requested each NPO submit written comments so they could provide the Planning Commission with input. He is now in the process of reviewing and responding to these comments. • Commissioner Owens continued that everyone is under a time pressure. They are continually hearing that there is not enough time to accomplish everything, especially from one person. There has been a tremendous amount of effort and energy from Bill and Jeremy providing them with information while also accepting all the input from the NPO's. At times it seemed the input was grinding the wheels to a halt. She felt the committee had come a long ways but she was still concerned about keeping the meeting going especially when they deal with the Housing and Transportation elements. • President Tepedino questioned if NPO #7 is still active. Associate Planner Coursolle stated the NPO #7 has been meeting, however they have not had a consistent membership. They only have six people on their NPO, but they do not appear consistently. They are committed to the task. 7. Meeting Adjourned 9:05 P.M. of - � 2 Diane Je `•er s, Secreto- r-.
