[NAME] maintenance and operating costs low
Respect Historic Resources | OVERALL +,+,0,+ | OVERALL +,-,0,0 | OVERALL -,0,+,0
• Minimize impacts to historic structures and features | • Naturalistic setting generally drives the shapes/slopes (+) | • Naturalistic setting generally drives the shapes/slopes (+) | • Naturalistic setting less evident (terracing shows less of “natural” terrain) (-)
• Maintain historic character of the site | [NAME] a pool of water (+) | • No visible water (-) | • Visible water is occasionally present (0)
[NAME] the historic function of the reservoirs in the context of the overall Portland water system | • City view is allowed for (though not celebrated) (0) | • City view is allowed for (though not celebrated) (0) | • City view appears to be celebrated (+)
• 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 and Gatehouse (+) | • Water is removed from the Dam and Gatehouse, though a flat expanse of turf could provide a strong link to a pool of water (0) | • Water is removed from the Dam and Gatehouse, though a flat expanse of turf could provide a strong link to a pool of water (0)
Be a Good Neighbor

• Enhance views into and from the area | • Largely a constructed natural looking element with limited ecological function – looks natural but little true natural amenity beyond the side slopes and path suggests movement not congregation  (-) | • Largely a constructed natural looking element with limited ecological function – looks natural but little true natural amenity beyond the side slopes (0) | • Increased natural/restored landscape area (+)
• Provide people with ability to connect with nature in the city

• 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 (+)
• Minimize climate change impacts due to construction, operations and maintenance. | Requires more energy and resources for pumping and chemicals (chlorine) to maintain water quality.  Least sustainable option. (-) | Requires lawn mowing, chemicals, and  maintenance equipment.  [NAME] is less sustainable than the "Habitat" option, but more sustainable than the "Reflecting Pool" option. (0) | Includes native plantings that require minimal chemicals.  Most sustainable option. (+)
• Promote wise use of our water resources through design, maintenance and education.
