ARCHITECTURAL MASSING Figure 1. Example of primary and secondary roof forms |
Figure 2. Create visual linkages. Offset building walls and rooflines. Incorporate similar roof forms and smaller design elements. (Note: The intent of this drawing is not to indicate that full-length porches are not acceptable for multi-family dwellings, but that design features must be considered along with overall form and massing to achieve compatibility.) |
ARCHITECTURAL MASSING and GARAGE PLACEMENT Figure 3. Create visual interest along the street. Incorporate porches, dormers, and bays to reduce scale of buildings and so as to relate better to existing structures. |
The Lake Oswego Master Plant List identifies plants appropriate for landscaping in specific areas, i.e., resource areas, street trees, West Lake Grove Overlay District, or for other purposes as established in this Code or elsewhere in the Lake Oswego Code, that either identifies plants that: | ||
a. | Are adapted to local soils and growing conditions, provide food and shelter for native wildlife, and generally do not require fertilizers or pesticides, and do not require long-term irrigation, which can increase erosion and sedimentation; or | |
b. | Are detrimental to existing vegetation, or to the functions and values where located, or to the character of the area where planted; or | |
c. | Meet the requirements of plants as specified in the particular sections of this Code, or elsewhere in the Lake Oswego Code. | |
This plant list is divided into the following subsections: | ||
1. | Native Plants. | |
2. | Invasive Plants. | |
3. | Street Trees – Prohibited. | |
4. | Street Trees – Approved (Applicable To LOC § 50.05.006.7.c, Old Town Design Standards Only). | |

2. | The campus-like character of the area will be maintained as much as possible. |
3. | Traffic and access will be controlled to preserve the capacity of Pacific Highway and the intersections at Marylhurst. Proper internal circulation will be provided. |
4. | The Willamette River Greenway will be preserved for scenic and recreational uses. |
1. | Designate the Marylhurst Campus for a variety of land uses and establish the specific uses, conditions and design criteria for subareas within the campus, to assure proper development. | ||
2. | Require each subarea to have a plan for circulation, utilities, and general building placement as a condition of approval for all development other than single-family subdivisions. | ||
3. | Establish permissible uses, intensities, development criteria and conditions for specific subareas within the campus, in addition to other policies. | ||
a. | SUBAREA I: CAMPUS INSTITUTIONAL | ||
1. | Allowed uses will include educational, religious, social service, governmental, institutional housing, and their supporting services. | ||
2. | The appearance and character of the present Marylhurst Education Center campus, especially the scale of buildings, building locations, materials, open areas and landscaping, will be continued in new development. | ||
b. | SUBAREA I-A: CAMPUS INSTITUTIONAL | ||
1. | Uses should be located in a major building and no more than two buildings. | ||
2. | Design of access to the eastern portion of the site must provide for emergency vehicles. | ||
3. | Development may not occur beyond the top of the banks of the drainage ways. Removal of trees will be minimized as much as possible. | ||
4. | Access into the site must be designed to be compatible with the existing Education Building, and should be located on the north side. | ||
5. | Vehicle access or parking in the eastern portion of the site will be discouraged. | ||
6. | Drainage management must be designed to prevent erosion of the banks of the drainage ways which have a severe potential landslide hazard. | ||
c. | SUBAREA II: CAMPUS INSTITUTIONAL | ||
1. | Commercial uses allowed (including Office Campus) must be buffered from Pacific Highway. | ||
2. | Structures will be located to maintain open areas which preserve a campus-like setting. The view of St. Anne’s Chapel from the southern access drive will be preserved. | ||
3. | Site design will orient buildings towards views and preserve highway and access road views as much as possible. | ||
d. | SUBAREA III: CAMPUS INSTITUTIONAL | ||
e. | SUBAREA III-A: RESIDENTIAL (R-10) | ||
1. | Access to Old River Road must be designed to provide a safe intersection, and to minimize disturbance to the wooded slope along the road. If these conditions cannot be met, the area must be provided access from the campus. | ||
2. | Residential development will be required to provide street trees. Development must be visually screened from the school and convent. | ||
3. | Emergency vehicle access from the campus side must be provided. | ||
4. | Change to topography will be the minimum necessary to develop the property. | ||
f. | SUBAREA IV: CAMPUS INSTITUTIONAL | ||
1. | Allowed uses will be Campus Institutional, including social service institutions and residential care facilities for the physically or mentally handicapped. Agricultural uses may be continued as long as they are compatible with new development. | ||
2. | A pedestrian access to Pacific Highway may be located at the north end of the site. | ||
g. | SUBAREAS V AND V-A: RESIDENTIAL (R-10 and R-15, respectively) | ||
1. | Allowed uses will be residential (R-10 and R-15), with clustering encouraged. | ||
2. | Site design should assure that views to the east are preserved and utilized. | ||
3. | A unified site plan for each subarea, required prior to development, shall include provision for buffering the adjacent residential areas. | ||
4. | Interior streets rights-of-way will be dedicated. Street trees will be required. | ||
The City will: | ||
1. | Assist Marylhurst in preparing architectural and site design criteria to be utilized as supplements to the development review standards for all future development at Marylhurst. The criteria will assure that development is harmonious with the existing campus buildings and landscaping. Criteria at minimum will assure: | |
a. | Maintenance of the architectural character of the existing buildings and landscaping. | |
b. | Scale, height, bulk, lot placement and building materials in new development which will maintain the open character and be properly related to the existing structures. | |
c. | Preservation of scenic vistas to the east. | |
d. | New landscaping will complement existing, especially types and placement of trees. | |
2. | Ensure that the natural drainage courses are designated as open space. No development will be permitted, except for utilities, drainage management improvements or low-intensity recreational improvements, such as trails. | |
3. | Ensure maintenance of a setback along Pacific Highway, which will include a minimum of 50 ft. from the right-of-way line, to provide for the planting of trees. The City will assist with providing and planting of the trees, subject to the budgetary process. | |
4. | Require buffers between nonresidential campus uses and adjacent residential neighborhoods, including protection of views. | |
5. | Require minimum changes in topography. Grading will be limited to that required for foundations, drainage management, parking areas and berms. | |
6. | Assure that parking areas are scaled proportionately to the campus buildings and are landscaped to avoid the appearance of large, unbroken paved area. | |
7. | Strongly encourage residential site design which is clustered and preserves open areas. | |
8. | Assure that commercial uses are of a type and size to serve the residents and users of the campus, without drawing a larger market, and are located away from Pacific Highway to avoid any strip development. | |
9. | Assure that utility construction will be coordinated with development and will prevent or minimize disruption of the existing buildings, streets, and drainage ways. | |
The City will (subject to the approval of the Oregon Department of Transportation, whenever applicable): | ||
1. | Limit access from the campus to Pacific Highway to the two existing access points. | |
2. | Limit land uses to the degree necessary to ensure that total vehicle trips generated by campus land uses maintain the capacity of Pacific Highway and intersections. | |
a. | Prior to new development, a traffic study will be prepared which will determine the projected volumes on Pacific Highway, the capacity available to future development at Marylhurst and improvements necessary to maintain the highway or intersections within Service Level "D." | |
3. | Require that Marylhurst pay an equitable share of the cost of improvements to Pacific Highway for additional capacity and signalization required for additional development. | |
4. | Actively seek transit improvements and increases in the levels of transit use in the Highway 43 corridor, to reduce vehicle trips entering the State Street Corridor. | |

ARCHITECTURAL MASSING Figure 1. Example of primary and secondary roof forms |
Figure 2. Create visual linkages. Offset building walls and rooflines. Incorporate similar roof forms and smaller design elements. (Note: The intent of this drawing is not to indicate that full-length porches are not acceptable for multi-family dwellings, but that design features must be considered along with overall form and massing to achieve compatibility.) |
ARCHITECTURAL MASSING and GARAGE PLACEMENT Figure 3. Create visual interest along the street. Incorporate porches, dormers, and bays to reduce scale of buildings and so as to relate better to existing structures. |
The Lake Oswego Master Plant List identifies plants appropriate for landscaping in specific areas, i.e., resource areas, street trees, West Lake Grove Overlay District, or for other purposes as established in this Code or elsewhere in the Lake Oswego Code, that either identifies plants that: | ||
a. | Are adapted to local soils and growing conditions, provide food and shelter for native wildlife, and generally do not require fertilizers or pesticides, and do not require long-term irrigation, which can increase erosion and sedimentation; or | |
b. | Are detrimental to existing vegetation, or to the functions and values where located, or to the character of the area where planted; or | |
c. | Meet the requirements of plants as specified in the particular sections of this Code, or elsewhere in the Lake Oswego Code. | |
This plant list is divided into the following subsections: | ||
1. | Native Plants. | |
2. | Invasive Plants. | |

3. | Ensure maintenance of a setback along Pacific Highway, which will include a minimum of 50 ft. from the right-of-way line, to provide for the planting of trees. The City will assist with providing and planting of the trees, subject to the budgetary process. | |
4. | Require buffers between nonresidential campus uses and adjacent residential neighborhoods, including protection of views. | |
5. | Require minimum changes in topography. Grading will be limited to that required for foundations, drainage management, parking areas and berms. | |
6. | Assure that parking areas are scaled proportionately to the campus buildings and are landscaped to avoid the appearance of large, unbroken paved area. | |
7. | Strongly encourage residential site design which is clustered and preserves open areas. | |
8. | Assure that commercial uses are of a type and size to serve the residents and users of the campus, without drawing a larger market, and are located away from Pacific Highway to avoid any strip development. | |
9. | Assure that utility construction will be coordinated with development and will prevent or minimize disruption of the existing buildings, streets, and drainage ways. | |
The City will (subject to the approval of the Oregon Department of Transportation, whenever applicable): | ||
1. | Limit access from the campus to Pacific Highway to the two existing access points. | |
2. | Limit land uses to the degree necessary to ensure that total vehicle trips generated by campus land uses maintain the capacity of Pacific Highway and intersections. | |
a. | Prior to new development, a traffic study will be prepared which will determine the projected volumes on Pacific Highway, the capacity available to future development at Marylhurst and improvements necessary to maintain the highway or intersections within Service Level "D." | |
3. | Require that Marylhurst pay an equitable share of the cost of improvements to Pacific Highway for additional capacity and signalization required for additional development. | |
4. | Actively seek transit improvements and increases in the levels of transit use in the Highway 43 corridor, to reduce vehicle trips entering the State Street Corridor. | |
5. | Ensure that internal streets on the east side of Pacific Highway will remain private streets, except for the residential area (subarea III-A). | |
6. | Require that internal access and circulation plans for each subarea of the campus will be prepared and approved as part of the development review for the first new development proposed for the subarea. | |
7. | Require dedication of an additional ten ft. of right-of-way on each side of Pacific Highway to widen the total to 80 ft. | |
8. | Ensure that a minimum setback will be maintained along Pacific Highway at 50 ft. from the right-of-way line to preserve the scenic corridor. | |
9. | Allow no vehicular access from Old River Road, except to subarea III-A. | |
10. | Assure safe pedestrian and bicycle circulation within the campus and each subarea. | |
a. | Whenever possible, walkways will be separated from vehicular ways. | |
The City will: | ||
1. | Assure that the area designated as Willamette River Greenway along Old River Road (generally from the river to the top of the steep bank above River Road) is maintained in a natural aesthetic condition. | |
a. | Structures will not be permitted in the Greenway, except for recreational purposes or utilities. | |
b. | Recreational improvements will be in scale with the environment. Parking areas, if any, will be minimal. | |
c. | Trees in the Greenway will be preserved. | |
d. | No boat ramps will be permitted. | |
2. | Designate the area between River Road and the river as Public Open Space, and the banks above the road and the drainage ways as Protection Open Space. | |
a. | The City will attempt to negotiate an agreement with Marylhurst which will provide for public access and recreational use of the land between River Road and the river. The agreement may be for purchase outright, easement use or other method mutually agreeable to Marylhurst and the City. | |
3. | Ensure that stormwater runoff from campus development will be controlled to avoid erosion, sedimentation or damage to the drainage ways. | |
