This is the first time Lake Grove has developed a Neighborhood Plan specific to the area contained within its neighborhood association boundaries (Figure 1). It was developed over a period of two years by the Lake Grove Neighborhood Plan Steering Committee and involved substantial research, review and discussion. The Neighborhood Plan has been incorporated into the City’s Comprehensive Plan by legislative amendment. It augments city wide land use goals and policies in regard to land use issues within the boundaries of the Lake Grove Neighborhood Association.

Development of the Lake Grove Neighborhood Plan involved the careful consideration of many different factors and issues to make the best decisions for the neighborhood for the short and long term. The goals and policies of the Neighborhood Plan and those of the Citywide Comprehensive Plan are intended to guide future land use decisions in the neighborhood. This Plan is intended for use by all those who have concerns with land use actions in the neighborhood, including local officials, persons with development interests, state, regional and federal agencies, neighborhood and community groups, and citizens of all interests.

Because the Neighborhood Plan is part of the Citywide Comprehensive Plan it is required to be in conformance with the City Plan, Statewide Planning Goals and the Metro Regional Framework Plan, which is also enabled by state statute. The Neighborhood Plan, prior to public hearings for adoption, was reviewed by both the City of Lake Oswego and the Department of Land Conservation and Development as to whether its meets these tests. Future changes are also evaluated as to consistency with the city, state and regional goals and policies.

The Lake Grove Plan consists of six goal and policy chapters as follows:

These chapters are numbered and structured to be consistent with the City’s Comprehensive Plan and statewide planning goals. Also, terms and phrases marked with an * asterisk are defined in a definition section at the end of the document.

It is important for both the Lake Grove Neighborhood Pan and the Lake Oswego Comprehensive Plan to be responsive to changing conditions and circumstances. Because the Neighborhood Plan is part of the citywide Plan its update is required as part of periodic review of the Comprehensive Plan to address changed and unanticipated circumstances which occur over time.

Also, because the Lake Grove Plan is intended to "comprehensively address" land use policy issues in the neighborhood, and the neighborhood is part of the City as a whole, there are no parts of either the City’s Comprehensive Plan or the Lake Grove Neighborhood Plan which can be considered separately from other parts. All Plan goals and policies are intended to be supportive of one another. However, when using the Neighborhood Plan to make decisions and conflicts arise between goals and policies, the City has an obligation to make findings, which indicate why the goal or policy being supported takes precedence over those which are found to be in conflict. This involves a decision-making process on the part of the City, which balances and weighs the applicability and merits of both the Neighborhood Plan’s and Comprehensive Plan’s many goals and policies against one another.

The City’s Comprehensive Plan and its Neighborhood Plan elements occupy center stage for directing Lake Oswego's future. However, other planning activities and documents are also important. Other plans such as the Park and Recreation Master Plan, Transportation System Plan, the various public facility plans, and the Capital Improvement Plan are important to consider when making land use decisions. However, any portion of these plans and any related action dealing with land use must be consistent with the policy direction of the Comprehensive Plan and its Neighborhood Plan Chapters.

The Neighborhood Plan elements of the Comprehensive Plan and the Zoning and Development Codes are intended to mutually support one another. The Plans do not contain specific standards for development. Instead they provide the policy basis for specific standards and procedures of the Zoning and Development Code which are used to review new development and modifications to existing development. However, the Plans are applicable to legislative decisions such as Plan and Zone Map amendments and certain other land use actions, which must address applicable Plan goals and policies. These include actions such as conditional uses and text changes to the City’s zoning and development codes."

Goals, policies and recommended action measures identify the intent of the City to accomplish certain results. The different types of plan statements vary in specificity. Usually, goals are the most general, and policies and recommended action measures are the most specific. The City's obligations under these statements vary according to the type of statement.

The goals and policies are intended to relate to one another. The goals are followed by supportive policies. The goals and policies in turn are supported by recommended action measures. However, each plan statement can stand alone, either as a goal or policy which are obligations the City wishes to assume, or as a recommended action measure which is a recommendation to achieve a desired end but does not signify an obligation.

The Comprehensive Plan is the general guide for the City in matters relating to land use. However, a number of other factors should be recognized:

The Lake Grove Neighborhood Plan Chapter on Citizen Involvement recognizes that the neighborhood is composed of both residential and commercial areas, which have specific needs and interests. The Plan’s Citizen Involvement goal and policies stress the need to involve all residents and businesses in all phases of land use planning. Furthermore communication within the neighborhood and to the City regarding significant issues must reflect the diversity of interests of those who live, work and do business in the neighborhood.

The chapter also recognizes the essential need to communicate and coordinate issues with the other neighborhood associations and County Planning Organizations (Rural Lake Grove Neighborhood) which border the Lake Grove Neighborhood.

The Plan stresses that the City’s current notification process does not provide adequate notice of impending land use issues. In some cases the current 300-foot notice does not notify all those who may be affected by a development proposal. The Neighborhood Plan Steering Committee felt that it was important to reach a threshold number of notified property owners to provide a greater opportunity for participation in land use matters. Therefore the Steering Committee crafted Goal 1, Policy 3, which states:

Furthermore, the Plan directs in Policies 4 and 5 that City staff, take a proactive and visible role in communicating development issues to the neighborhood. Policy 5 directs that City staff notify both the Neighborhood Association Board and the Lake Oswego West/Lake Grove Business Association as soon as land use applications are accepted as complete. Many land use issues applications and resultant staff reports involve an analysis of many complex issues such as traffic, public facilities, surface water quality, natural resources protection and neighborhood compatibility. The Neighborhood Planning Steering Committee felt that it is important for the neighborhood to have as much time as possible to review these issues and prepare comment because of past experience of not having enough time to do so. Therefore, the policy also directs the City to provide an opportunity for the Neighborhood Association Board to meet with staff at least seven days prior to the required 10-day availability of the staff report to discuss land use applications and staff’s preliminary analysis.

Policy 6 ensures that pre-application meetings between applicants and the neighborhood are meaningful and that concerns and issues are accurately communicated. Policy 6 as presented below proposes specific ways by which this should happen:

A defining feature of the Lake Grove Neighborhood is its namesake -- the tree canopy that predominates throughout the area. Eighty-two percent of the 223 persons who responded to the neighborhood survey conducted by the Neighborhood Planning Steering Committee in 1995 responded affirmatively that policies should be established to protect trees and other natural resources.

A major focus of the Plan’s Goal 5 chapter is preservation of and enhancement of the tree canopy. Furthermore, the Plan recognizes the benefits of the City’s Sensitive Lands Protection Program and stresses protection of the neighborhood’s stream corridors, tree groves and wetlands as designated by the City’s ESEE analysis. The Plan also recognizes the benefits of the City’s Open Space Standard and emphasizes in Goal 5, Policy 2 the need to take specific action to preserve and maintain open space.

The Goal 5 Chapter identifies specific policy action to provide a greater level of tree protection and enhancement of the neighborhood tree grove. Policy 3 proposes to amend the LOC Chapter 55 as follows:

This policy also proposes that the City amend its Development Standard to ensure that:

Policies 4 through 10 also emphasize tree protection. In summary these policies state:

• Require, when practicable*, tree planting for all new development including single family homes;
• That the development review process emphasize protection of significant trees rather than allowing removal and subsequent mitigation through replanting;
• Provide property owners the opportunity to preserve trees through participation in a City adopted Heritage Tree Protection Program*.
• Protect and enhance significant trees within the public right-of-way and on other public lands, and;
• Monitor the Neighborhood’s tree canopy over time through a city-maintained data collection and inventory system.

Springbrook Creek is the neighborhood’s primary stream corridor and policies 11, 12 and 13 address protection of this natural resource. The Neighborhood Plan Steering Committee stressed that it is particularly important to protect the stream corridor and adjoining properties from erosion and sedimentation, which could result from upstream development. Furthermore, these policies address the need to protect the stream corridor and adjoining property from damage if any portion of Springbrook Creek sewer interceptor should fail.

The Chapter’s Recommended Action Measures (RAMs) identify several sites in the neighborhood that have local historic and cultural significance. Also, the RAMs identify several sites as candidates for landscaping and beautification.

Preserve Lake Grove Neighborhood’s natural resources and wooded character.

The Lake Grove Commercial District is a significant and defining part of the neighborhood. Business and residential property owners realize that a positive relationship is essential to further the interests of both. Therefore, the emphasis of the Goal 9: Economic Development/Commercial Lands Chapter is, per its Goal to:

This goal is proposed to be accomplished by specific actions embodied in the following policies which are intended to ensure future transportation improvements are multi-modal in nature and result in a safe and efficient transit and pedestrian environment. Particularly important to the area businesses and the residential neighborhood is the ability of Boones Ferry Road to provide for safe access to area businesses, while maintaining the character and function of the adjacent local street system. The goal and policies for the Economic Development/Commercial Lands Chapter are also intended to ensure:

• Opportunities for mixed use development (residential/commercial) within the business district;
• That the design quality of the business district is enhanced by enacting specific land use and design regulations;
• Future commercial development protects trees and other natural resources, especially mature Douglas Firs;
• Tree planting and quality landscaping occurs whenever possible, and
• Compatibility is enhanced between the business district and the residential neighborhood through enactment and enforcement of land use regulations which address issues such as outdoor lighting, buffering and screening, and abatement of nuisance situations. In this context, the Neighborhood Plan Steering Committee stressed that it is important not to allow new drive-in or drive-through food service windows.

It is important to stress that both business and residential representatives on the Steering Committee agreed that it was appropriate to establish a boundary beyond which the Lake Grove Commercial District would not expand into the residential portion of the neighborhood. This Boundary is specifically outlined in Goal 9, Policy 10.

Promote policies and actions which support the viability of the Lake Grove Commercial District and its ability to provide goods and services to area residents and businesses in an innovative manner compatible with the character of surrounding residential neighborhoods.

The intent of this chapter is to "preserve the livability and aesthetic quality of Lake Grove’s residential neighborhoods." The policies developed by Lake Grove Neighborhood Plan Steering Committee propose to accomplish this goal by stating that:

• The existing housing stock is to be preserved and low-density single family uses shall be the predominant land use in the neighborhood;
• Deterioration and/or demolition of existing single family homes on lands zoned for single-family residential uses are not to be used as reasons for plan and zone amendments to commercial or industrial uses or to higher residential densities than allowed by the current zone.
• Design compatibility standards are to be used to ensure all new residential development, including substantial remodeling, contributes to the positive design character of the neighborhood;
• Preservation of the character of existing non-urban local streets is important including, the non-grid street pattern and preservation of trees within rights-of-way and on adjacent property which provide tree canopy and shade;
• Infill development and secondary housing units may be allowed, including flag lots, subject to specific design and development standards to ensure design compatibility;
• An appropriate mix of high-density housing and office commercial land uses should be allowed on both sides of Boones Ferry Road between Madrona Street and the Railroad tracks subject to very specific, design and engineering criteria;

The Goal 10, Housing/Residential Land Use Chapter also addresses issues and problems caused by nuisances, non-compliant home occupations and storage of vehicles, boats and equipment within the public right-of-way. This chapter contains the same policy as in Economic Development/Commercial Lands Chapter, Goal 9 that specifically demarcates the boundary between the commercial and residential portions of the neighborhood.

Preserve the livability and aesthetic character of Lake Grove’s Residential Neighborhoods.

The Neighborhood Plan’s Goal 11: Public Facilities and Services Chapter recognizes that the City of Lake Oswego Comprehensive Plan contains numerous policies which are applicable to the community as a whole. In view that the City wide Plan is generally sufficient, this element of the Neighborhood Plan was developed to apply to the Lake Grove Neighborhood’s specific conditions, character and needs. The Plan Chapter addresses Police and Fire Protection, Storm Water and Surface Water Management, Water Treatment and Delivery, and Private Utilities and Schools. The common emphasis of the Goals and Policies is to ensure that the Lake Grove Neighborhood is provided with high quality, responsive and environmentally sound public facilities and services.

The Plan Chapter lists, and proposes implementation of specific projects derived from the City’s Public Facility and Capital Improvement Plans. It also proposes other projects identified by the neighborhood. Most significant of these specific neighborhood projects is localized flooding caused by an inadequate storm drainage system.

The City of Lake Oswego Comprehensive Plan contains numerous policies in the Goal 11: Public Facilities and Services Chapter, which apply to the Lake Grove Neighborhood and the rest of the Community. The following policies have been developed to be specific to Lake Grove neighborhood’s specific conditions, character and needs. They are intended to be supportive and complementary to the other Comprehensive Plan policies, which apply citywide.

The Lake Grove Neighborhood has identified a range of specific public facility issues and projects that pertain specifically to the neighborhood. These are summarized in the attached, "Lake Grove Neighborhood - Public Facility Projects and shown on Figure 5." These specific projects are subject to periodic review and revision when the City’s Public Facility Plan* and Capital Improvement Plan* are updated.

Provide Lake Grove neighborhood residents and businesses a high level* of police, fire protection and emergency preparedness services.

In the Lake Grove Neighborhood, reduce, and where possible eliminate, flooding, soil erosion, standing water in the public right-of-way, and water pollution associated with storm water runoff.

Ensure Lake Grove neighborhood residents and businesses receive a reliable and adequate supply of high quality domestic water to meet consumption and fire flow requirements.

Ensure Lake Grove Neighborhood residents and businesses, which are within the City limits, receive environmentally safe and reliable sanitary sewer service.

Ensure private utilities provide reliable, high quality service to Lake Grove neighborhood and that neighborhood families are assured of close-to-home educational opportunities for their children.

SANITARY SEWER
PFP Project SS-1 - East Mountain Park Drainage Basin Flow Monitoring

A substantial portion of the Lake Grove Neighborhood is within this sewer drainage basin. The sewer system in this area is relatively old compared to other parts of Lake Oswego. It is important to monitor the system’s condition and undertake needed repairs prior to problems developing. When repairs become necessary, they usually consist of line and manhole rehabilitation, reconnections of service laterals, elimination of cross-connections between sanitary sewers and the surface water system with the objective of reducing infiltration and inflow* problems.

If actual sewer line rehabilitation is needed in this area, it will be scheduled as part of the CIP update. No cost has been assigned since this is an on-going and budgeted maintenance function.

The portion of this project within the Lake Grove Neighborhood is located within public easements between Boones Way and Boones Ferry Road north of Red Cedar Way; at the east end of Brookside Road and, within Lakeview Boulevard and Springbrook Court.

The City of Lake Oswego Sewer Utility Model has indicated the need for continuing monitoring of this interceptor line because it may be too small for projected flows. Flow monitoring will continue to evaluate the situation and determine if and when actual problems may occur. Excessive flows can lead to premature pipe and joint wear and manhole surcharging. The City’s continued infiltration and inflow (I&I)* projects are one way to substantial reduce the flows entering this line. If the I&I program is successful upgrade of the sanitary sewer line may not be necessary. If reduction in I&I does not occur to satisfactory levels it may be necessary to replace existing sewer mains with larger diameter pipe.

This project was scheduled in the CIP for 1997 and 1998 and has been put on hold to determine its actual need as described above. Its estimated 1997 cost was $236,000.

This project proposed to extend sewers outside the City limits within the Lake Grove Neighborhood to about 37 properties within both the City limits and unincorporated Urban Services Boundary which are currently served by septic tanks. These properties are located generally between Bryant Drive and Boones Ferry Road.

Many septic tanks and drain-fields in this area may be beyond their viable design life and there may not be adequate replacement area on existing lots. The project would have been initially been funded by the City Sewer Extension Program*. Connection to sewer would have occurred as septic tank systems failed or on a voluntary basis. The cost would have been about $10,250 dollars per dwelling unit equivalent. In this instance, because the cost for connection is based on a citywide average it is less than if the sewer was extended without the benefit of the City’s participation. However, a majority of residents expressed their opposition to project because it would bring the prospect of new development to the area and in their view change the neighborhood character. Furthermore, these properties would be required to annex to the City prior to the receipt of sewer. Due to opposition to the project the City has decided not proceed with funding it in the near future.

This project was originally identified in the CIP for implementation in 1999/2000 and would have cost about $310,000.

The Lake Grove Neighborhood has identified a number of localized flooding problems which represent potential damage and safety problems and are inconvenient for neighborhood residents. These are also identified on Figure 6 and are summarized below.

Standing water is problem on the length of Sunset Drive between Reese and Bryant Roads and on Upper Drive between Bryant and Boones Ferry Road. In addition, standing water also tends to occur at the following locations throughout the neighborhood:

• 3200 Upper Drive;
• 3565 Upper Drive;
• At the stop sign at the corner of Lanewood and Douglas Circle;
• 15867 Twin Fir Road;
• 3718 Lake Grove Avenue;
• 4839 Upper Drive;
• 16112 and 16251 Reese Road;
• 16054 Reese Road;
• At the intersection of Reese Road and Upper Drive;
• 3200 Upper Drive; and
• 3355 Upper Drive

The above localized flooding problems are candidates for the CIP "Small Works" projects. These are minor projects, which are less than $25,000 in cost and include construction of catch basins, manholes and short reaches of storm drainage pipe. These projects are typically constructed with larger utility projects or several smaller projects are constructed as part of one construction contract.

This project proposes to replace and relocate existing undersized storm lines with much larger, 21 inch diameter pipe, beginning at Bryant Road and the railroad crossing to about 420 feet south. It will reduce flooding and resultant property damage. It will also provide the City with access for line cleaning and other maintenance tasks. This project is also identified in the CIP for implementation in 1999/2000 and is anticipated cost is $93,000.

These projects will protect existing infrastructure and reduce flooding damage to adjacent properties. Although, flooding does not occur on an annual basis, the drainage system at these locations is undersized. Significant flooding does occur during large infrequent storms. The project will replace existing undersized culvert pipe with box culverts. It is scheduled for 1998 and is projected to cost $393,000.

This project originated as part of the City’s Surface Water Management Plan and proposes to increase the capacity of culverts which cross Kruse Way and Mercantile Drive to the Mercantile detention basin. It also proposes to install a new, larger culvert under Boones Ferry Road, which discharges into Springbrook Creek. The necessity for the project has yet to be determined and will depend on surface water flow monitoring. It is anticipated that little development will occur upstream and that today’s flows, which are adequately handled by the existing system, will not increase substantially. The need for this project will continue to be monitored.

This project is proposed Citywide to install isolation valves on major water transmission lines to allow water to be turned off in the event of an earthquake. It is scheduled in the CIP for 2000/2001 and is budgeted for $400,000.

This is a long term project intended to construct a new finished water main to the Waluga Reservoir when and if the City Water Treatment Plan is expanded. Within the Lake Grove Neighborhood it is identified to follow Iron Mountain Boulevard and connect to Brookside and follow Red Cedar Way to Douglas Way. The need for this project will continue to be monitored.

This is a long-term project, which would retrofit the Waluga Reservoir for earthquake protection. The project is significant for the Lake Grove neighborhood is within the Waluga Reservoir pressure zone.*

The Lake Grove Neighborhood Plan Transportation Goals and Policies emphasize that the neighborhood’s transportation system is an integral element of the character and design quality of the neighborhood. The direction of the chapter is to:

• Improve safety of all transportation modes;
• Maintain the aesthetic quality, privacy and quiet of residential areas;
• Provide for adequate traffic movement and access within residential and business areas appropriate to the aesthetic character, transportation, and safety needs of each area, and;
• Provide practicable pedestrian, transit, parking and bicycling opportunities.

The Plan’s goal and policies propose to maintain the small-scale "country lane" character of the Lake Grove neighborhood’s local residential streets and neighborhood collectors and ensure that improvements to the major street system accommodate through traffic to prevent its diversion onto the local system. The Neighborhood Plan Steering Committee was also very specific that traffic management devices were appropriate to prevent speeding and cut-through traffic on local streets. On local streets, the Steering Committee desires to:

• Utilize flexible design standards and innovative surface water management solutions to ensure pavement width and street design is appropriate for the function of the street and needs of the area served;
• Not require the dedication of unnecessary right-of-way or construction of standard full width, curbed and guttered urban streets as a condition of residential development approval, and
• Ensure the opportunity for safe on-street public parking on graveled shoulders.

The Plan also proposes standards for bicycle and pedestrian facilities in the neighborhood by stating that walking and biking should be accommodated on at least one side of all neighborhood collectors and selected local streets and on both sides of arterial and collectors. Furthermore it stressed that greater access to transit services is necessary. In particular, the neighborhood seeks to realize the potential of commuter rail. However, the plan policy in this regard seeks to reinforce the positive and mitigate the potential negative impacts of future rail travel though the neighborhood.

The ability of Boones Ferry Road to accommodate future traffic and provide needed access to area businesses is an important element of this Plan Chapter. Recommended Action Measures stress the need to develop a specific transportation study for the Commercial District focusing on Boones Ferry Road and affected local streets. Also, the RAMs support greater transit access and improved facilities on Boones Ferry Road; a Lake Grove Neighborhood Transportation Management Association; coordination of transportation issues with other nearby Metro designated Regional and Town Centers, and development of a parking strategy for the Lake Grove Commercial District.

Ensure that the transportation system in the Lake Grove Neighborhood enhances neighborhood character and quality by:

Terms and phrases which are marked by an asterisk *in the above text are defined below
300 Foot Notification Boundary: This term refers to owners of property who are provided notice pursuant to LOC 49.40.805 and 49.44.920 prior to decision on major or minor development applications. Owners of property within 300 feet of the entire contiguous site for which the application is made receive notice. The property owner list is be compiled from the most recent property tax assessment roll. Notice shall also be sent to any recognized neighborhood association whose boundaries include the site. The Planning Director shall certify that such notice was given.

Aesthetic Entry (to the Lake Grove Neighborhood): For the purpose of implementing LGNP Goal 10, Policy 6 (f), this term refers to the requirement to continue an attractive and visually interesting transition sequence from the City of Tualatin to the City of Lake Oswego and continue and expand upon the design requirements of the Boones Ferry Jean Road Site, [LOC 48.10.315 (13) and the Jean Way Site [LOC 48.10.315] (14). The development of an aesthetic entry to the Lake Grove Neighborhood shall include:

The development of a variety of architecturally designed structures of high design quality; in scale with the site; in proportion to similar buildings in the Lake Grove Commercial District and which utilize a pleasing variety of materials, colors, finishes and textures;

Capital Improvement Plan (CIP): The City of Lake Oswego’s Capital Improvement Plan (CIP) is a five-year planning programming, and financing plan for protecting the City’s investment in its infrastructure and for constructing new facilities to meet increased service demands. Each year, Lake Oswego’s CIP is updated and presents a prioritized schedule of major public improvements that will be implemented within a five year period and their possible sources of funding.

City Sewer Extension Program: This program has been established by City Ordinance (Ord. 2010) and incorporated into LOC Chapter 40, Improvement Procedure. It is intended to facilitate the extension of sanitary sewer service to the unsewered areas of the City limits and unincorporated Urban Service Boundary. The program allows the City to coordinate street overlays with the extension of sanitary sewer service; construct projects that serve an entire area and avoid piecemeal construction, and extend service to areas with failing septic systems.

Under this program, the City provides the initial funding for extension of the main sewer line. Connection to the sanitary sewer system is required when a property owner’s septic system failed or at the owners request. The City recovers its initial cost by imposing a line charge to property owners at the time of connection. This cost is determined by the number of connections possible for the property.

Closest fifty property owners (for notification purposes): The intent of the Lake Grove Neighborhood Plan, Goal 1, Policy 3 is to provide for fifty property owners to receive notice of development applications which propose minor or major developments. When less than fifty persons are contained within the required 300 foot notification area as defined below, the closest property owners from the subject property shall receive notice until the sum of those to be notified equals fifty.

Cohesiveness (of residential neighborhoods): This term, for the purpose of implementing LGNP Goal 10, Policy 6 (b), is defined as the physical continuity of residential land uses unbroken by intervening commercial land uses or major streets (major collectors, and arterials).

Cohesive Quality of Tree Groves: For, the purpose of implementing LGNP Goal 5: Policy 3(b) this term is defined as the closely contiguous and often-times interweaved tree canopy which forms a visual and biological unit pursuant to the definition of "tree grove" below. A cohesive tree grove also serves to protect individual trees within said grove from storm damage by virtue of its ability to withstand high winds more so than individual trees.

Conservation Easements: The granting of conservation easements is made possible by LOC Chapter 59 which establishes a process to encourage the voluntary retention and protection of the natural, scenic and open space values of the community by private property owners through donation or dedication of easements to the City or other non-profit or governmental organization whose purpose is to protect these resources.

County Planning Organizations (CPOs): County Planning Organizations (CPOs) are comparable to the City of Lake Oswego Neighborhood Association and are chartered by Clackamas County. There are three CPOs in the Lake Oswego Urban Services Boundary and adjacent to the City limits. They are the Rosewood, Forest Highlands, and Rural Lake Grove CPOs. The Rural Lake Grove CPO shares a boundary with the Lake Grove Neighborhood Association.

Cut-Through Traffic: Cut-through traffic is through traffic or auto trips, which have neither trip end nor beginning within the neighborhood association boundary. Pursuant to Lake Oswego Comprehensive Plan, Goal 12, Sub-Goal 1, cut-through traffic is discouraged on residential streets and neighborhood collectors.

Dangerous and Unsafe Buildings: These are buildings or structures that regulated pursuant to the City of Lake Oswego Building Code [LOC Chapter 45] which are structurally unsafe or not provided with adequate egress, or which constitute a fire hazard or are otherwise dangerous to human life. The Building Code pursuant to LOC 45.09.060 declares any use of these structures which constitute a hazard to safety, health, or public welfare by reason of inadequate maintenance, dilapidation, obsolescence, fire hazard, disaster damage or abandonment as an unsafe use. Also declared unsafe are parapet walls, cornices, spires, towers, tanks, statuary and other appendages or structural members which are supported by, attached to, or part of a building and which are in a deteriorated condition or otherwise unable to sustain design loads specified in the lake Oswego Building Code. Dangerous and Unsafe Buildings may be abated by the City of Lake Oswego.

Flag Lots: A flag lot is a lot located behind another lot that has normal street frontage and where access is provided to the rear lot via a narrow "flag pole" (i.e. driveway), or where access is provided via an easement. There are two distinct parts of a flag lot; the flag, which comprises the actual building site, located behind another lot, and the pole, which, provides access from the street to the flag. A flag lot results from the division of a large lot with the required area and depth for two lots, but which has insufficient width to locate both lots on the street frontage. The creation of flag lots are subject to specific criteria within LOC 48.19 to enhance compatibility with the surrounding residential neighborhood.

Goal 5 ESEE Natural Resources Inventory: The Economic, Social, Environmental and Energy Analysis (ESEE) is defined by LOC 48.02.015 and is required pursuant to Statewide Planning Goal to regulate natural resources with the purpose of ensuring their protection. The purpose of the ESEE analysis is to balance the relative value of an inventoried natural resource against conflicting uses and thereby determine an appropriate level of protection through land use regulations. The ESSE Analysis forms the factual basis for the Lake Oswego Sensitive Lands Program (LOC Article 48.17) and was used initially to designate properties for protection. The City’s ESEE Analysis is available as the Lake Oswego Resource Areas Report and ESEE Analysis, dated April 1, 1997, as revised July 15, 1997.

Heritage Tree Protection Program: The Heritage Tree refers to City Ordinance No. 2159 which is intended to recognize, foster appreciation of and provide for the voluntary protection of "Heritage Trees." A Heritage Tree(s) is a tree or stand of trees stand of trees of landmark importance due to age, size, species, horticultural quality or historic importance

High level of police, fire protection and emergency preparedness services: For the purposes of the LGNP, this term is described as:

Infiltration and Inflow (I &I): This term is used to describe extraneous components of wastewater flow. Infiltration occurs when groundwater leaks into the sanitary sewer through defects such as cracked or broken pipes, poor joints or dilapidated manholes. Inflow occurs when storm runoff flows directly into the sanitary sewer system at storm sewer cross connections, roof and foundation drains, catch-basins and faulty or submerged manholes.

Invasive Vegetation: This term is defined by the Lake Oswego Development Code, LOC 48, as vegetation that displaces or dominates the natural plant communities such as Himalayan blackberry English ivy, reed canary grass, scotch broom, etc. A list of such plants is maintained on file at the Lake Oswego Department of Planning and Development.

Lake Oswego Neighborhood Association Coalition (LONAC): LONAC is an organization composed of representatives of the Lake Oswego’s Neighborhoods not charted by the City which serves as a forum to discuss and represent the common interests of the community.

New and Existing Residential Lots: For the purposes of implementing LGNP, Goal 10, Policy 4, new and existing residential lots are defined as:

Home Occupations: home occupations are defined by LOC 49.02.015 as a lawful use conducted in a residential zoning or on the premises of a dwelling unit, said use being secondary to the use of the dwelling for dwelling purposes. Home occupations are regulated by LOC 48.20.545, which states:

A home occupation may be conducted where allowed by other provisions of this chapter if the following conditions are continuously complied with:

Landmark Status (pertains to mature trees especially Douglas Firs): The landmark status of mature Douglas Fir trees refers to their visual preeminence within the landscape and their contribution to the identity and aesthetic quality of the neighborhood. These trees represent significant landmarks because they contribute to a sense of special identity and character.

Mature Douglas Fir Trees: These are trees that have obtained a height of 70 feet.

80% of Maximum Allowed Density: 80 % of maximum allowed density is established requires development of the number of allowed residential units to be at least 80% of the "net density" allowed by the underlying zone.

Minor and Major Development: Minor Development is defined by Section 49.20.110 of the Lake Oswego Development Code and is a development, which requires a permit from the City that requires a more discretionary level of review than a ministerial decision which is defined in LOC 49.20.105. Minor Developments are initially decided by the Planning Director subject to notice, the opportunity to request a hearing and appeal as provided by LOC 49.40.800 to LOC 49.40.820. Minor development is also intended to include decisions defined as "limited land use decisions" pursuant to ORS 197.020 (12).

Minor Development includes:

Major Development includes:

Natural Resource Functions and Values: For the purpose of implementing LGNP Goal 5, Policy 5, natural resource functions and values are defined in LOC 48.02.015 as the benefits provided by natural resources. The benefits may be physical, environmental, aesthetic, scenic, educational, or some other non-physical function or a combination of these. For example, the functions and values of a wetland can include its ability to provide storm water detention for "x" units of water draining "y" acres and its ability to provide food and shelter for "z" varieties of migrating waterfowl. In addition, an unusual native species of plant and a natural resource area could be of educational, heritage or scientific value. Most natural resources have multiple functions and values. For example Stream Corridors, Tree Groves and wetlands share some or all of the following beneficial characteristics:

Natural Drainage System: This term refers to the open and vegetated drainage channels and the surface water treatment facilities which comprises the great majority of Lake Oswego’s storm water conveyance system.

New Development: For the purpose of implementing LGNP, Policy 4, "new development" is intended to include the following:

Nuisance Situations: Nuisances are broadly defined as anything which interferes with, annoys or disturbs the free use of one’s property or which renders its ordinary use or physical occupation uncomfortable. This definition extends to everything that endangers life or health, gives offense to the senses, violates the laws of decency, or obstructs the reasonable and comfortable use of property. Nuisances also refer to wrongs arising from an unreasonable or unlawful use of property to the discomfort, annoyance, inconvenience or damage of another. This usually involves continuous or recurrent acts.

A public nuisance is further defined by LOC 34.08.400 as:

Obvious Immediate Hazard: Pursuant to LOC Chapter 55, and for the purposes of LGN Plan (Goal 5, Policy 3(a) ) trees which pose an obvious immediate hazard are ones which clearly present a public safety hazard or a foreseeable danger of property damage to an existing structure and such a hazard or danger cannot be reasonably alleviated by treatment or pruning.

The Planning Director may require neighborhood contact pursuant to this Section prior to the filing of an application for any other development permit if the Director deems neighborhood contact to be beneficial.

The purpose of neighborhood contact is to identify potential issues or conflicts regarding a proposed application so that they may be addressed prior to filing of an application. This contact is intended to result in a better application and to expedite and lessen the expense of the review process by avoiding needless delays, appeals, remands or denials. The City expects an applicant to take the reasonable concerns and recommendations of the neighborhood into consideration when preparing an application. The City expects the neighborhood association to work with the applicant to provide such input.

Public Facility Plan (PFP): The City’s PFP identifies the major facilities and capacity improvements to city infrastructure that are necessary to support land uses allowed by the Comprehensive Plan. These facilities include water, sanitary sewer, storm drainage and surface water management, and major transportation improvements. The PFP is used in conjunction with the CIP as described above to coordinate, program and phase public facility funding decisions.

PFPs are required by Statewide Planning Goal 11, Public Facilities and Services for all cities with populations greater than 2,500 to ensure that cities plan and develop timely, orderly and efficient arrangements of public facilities and services to serve as the basis of urban development.

Pathways, Walkways, and Sidewalks: For the purpose of LGNP, Goal 10, Policy 2, walkways are defined as paved or graveled pedestrian ways within the public right-of-way usually at the same grade with an adjacent street. Pathways may be also separated from the street by an intervening landscaped strip. Pathways are multi-purpose-paved areas intended to accommodate both pedestrians and bicyclists. They may be also adjacent and at the same grade as the street or separated by a landscaped strip. Pathways and walkways are contrasted to urban sidewalks, which are typically constructed in conjunction with curbs, gutters and a piped storm drainage system.

Skinny Streets: In the context of the LGNP "skinny streets" are those which are developed to a minimum driving width necessary to provide required access to adjacent residential land uses and to allow for emergency vehicle access. In some instances this may allow for the construction of "queuing" streets which are intended for two-way traffic, but are comprised of a single traffic lane and a parking lane on one or both sides of the street. When two vehicles meet, one of the vehicles must yield by pulling over into a vacant segment of the adjacent parking lane.

Sight Distance Problems (pertains to streets): Sight distance problems occur when vegetation or other materials obstruct the view of drivers, pedestrians or bicyclists at street intersections.

Significant Trees and other Landscape Features: Significant trees in the Lake Grove Neighborhood are those evergreen trees 30 feet and taller and deciduous trees with a diameter of 10" or greater and a height of 30 feet or more.
