Washington Park Reservoir Improvements Project - Options Discussion Evaluation Framework - Preliminary September 2013
 | Reservoir No. 3
Goals and Objectives | Water Over the Divide | In the Ravine | Landscape Terraces | Cascade
Be Good Stewards of Public Funds | OVERALL 0, - | OVERALL +, + | OVERALL -, 0 | OVERALL 0, -
• Ensure costs provide the greatest community benefit | Construction Cost: $$ (0) | Construction Cost: $ (+) | Construction Cost: $$ to $$$  (-) | Construction Cost: $$ (0)
• Prudently spend public money & limit impact on ratepayers | Operation & Maintenance Cost: $$$ (-) | Operation & Maintenance Cost: $ (+) | Operation & Maintenance Cost: $$ (0) | Operation & Maintenance Cost: $$$ (-)
[NAME] maintenance and operating costs low
Respect Historic Resources | OVERALL -,+,0,0,+ | OVERALL +,-,0,-,- | OVERALL +,-,0,0,- | OVERALL +,+,-,+,+
• Minimize impacts to historic structures and features | • Naturalistic setting less evident (shapes less driven by natural landscape) (-) | • Naturalistic setting more evident (shapes driven by natural landscape) (+) | • Naturalistic setting more evident (shapes “inspired by” natural landscape) (+) | • Naturalistic setting more evident (shapes “inspired” by natural landscape) (+)
• Maintain historic character of the site | [NAME] a larger expanse of water (though divided) (+) | [NAME] a smaller expanse of water (-) | [NAME] a smaller expanse of water (-) | [NAME] a larger expanse of water (+)
[NAME] the historic function of the reservoirs in the context of the overall Portland water system | • View from north is impacted, but possibly less so with lower (306’) wall near gatehouse (neutral) | • View from north is impacted, but less so with landscaped slope down to Gatehouse (neutral) | • View from north is impacted, but less so with lower “wall” height next to Gatehouse (neutral) | • View from north is significantly impacted (-)
• Retain the sites reflective & tranquil character that is now created & heightened by the visual connection to an expansive water. | • Water is next to the dam, but very limited at Gatehouse (neutral) | • Water is removed from the Dam and Gatehouse (-) | • Water is next to the dam, but very limited at Gatehouse (neutral) | • Water is next to the dam and Gatehouse (+)
 | • Upper and lower pools do express water under effect of gravity (+) | • Less expression of water under effect of gravity (could be re-evaluated depending on Reservoir 4 scheme) (-) | • Less expression of water under effect of gravity (could be re-evaluated depending on Reservoir 4 scheme) (-) | • Cascading pools express water under effect of gravity (+)
Be a Good Neighbor
• Reduce use of neighborhood parking by park visitors
• Avoid attraction of nuisance & illegal activities into the park & neighborhoods
• Enhance the quality of the park as an amenity for neighbors & visitors
• Minimize construction impacts
Enhance Park Experience | OVERALL +, +, 0 | OVERALL -, 0, + | OVERALL -, +, + | OVERALL +, 0, 0
• Provide public access & opportunities for low-intensity recreation | • Large expanse of water (+) | • Smallest amount of water although the reflecting pool is highly visible from above (-) | [NAME] amount of water (-) | • Large expanse of water (+)
• Retain the sites reflective & tranquil character that is now created & heightened by the visual connection to an expansive water. | • New experience and new views available from the promenade and potentially from walkway between reflecting pools (+) | • Views are more internally focused (0) | • Ample opportunities to view other parts of the site (+) | • Views are largely from the promenade – fewer new viewing opportunities (0)
• Enhance views into and from the area
• Provide people with ability to connect with nature in the city | • Less connection to nature as this would be a more constructed environment (0) | • More opportunity for softened topography and areas of landscape restoration with paths winding through (+) | • Increased amount of landscape area and more opportunity to feel part of nature (+) | • Increased sounds of nature through cascading waterfalls- white noise provides a greater sense of privacy and separation although it is a constructed natural setting, not truly natural (0)
• Maintain security of the park and water facilities
• Ensure the new visible features enhance current park uses and are compatible with future park uses
Support Sustainability | OVERALL 0, -, - | OVERALL +, 0, 0 | OVERALL +, 0, + | OVERALL 0, -, -
• Create sustainable landscapes that provide habitat for birds and other native wildlife | • Provides same habitat area as existing site(0) | • Provides an increase in habitat area compared to existing site (+) | • Provides the most increase in habitat area compared to existing site (+) | • Provides same habitat area as existing site(0)
• Minimize climate change impacts due to construction, operations and maintenance. | • Water fall feature from upper to lower reflecting pools requires more energy for pumping & chemical use: less sustainable (-) | [NAME] water area requires less operation and maintenance: more sustainable. (0) | [NAME] water area requires less operation and maintenance: more sustainable (0) | • Water cascading feature from upper to lower reflecting pools require requires more energy for pumping & chemical use: less sustainable (-)
• Promote wise use of our water resources through design, maintenance and education. | • Lower reflecting pool on landslide area will have settlement issues and upper reflecting on buried reservoir will have significantly less settlement issues. Same as "Cascade", least sustainable.  (-) | • Lower reflecting pool on landslide area will have settlement issues: less sustainable.  (0) | • Upper reflecting on buried reservoir will have significantly less settlement issues: most sustainable. (+) | • Lower reflecting pool on landslide area will have settlement issues and upper reflecting on buried reservoir will have significantly less settlement issues. Same as "Water Over the Divide", least sustainable. (-)
