Portland Parks & Recreation and the Portland Water Bureau are in the final weeks of gathering public input on the planned improvements at Powell Butte Nature Park that will be implemented in conjunction with a new underground 50-million gallon reservoir at the park. The organizations unveiled design plans for a new interpretive center, restrooms, caretaker’s house and maintenance building, at a January 25 open house, located at Parklane Christian Reformed Church on SE 160th Avenue and Main Street. They also unveiled several concepts for improvements and rerouting strategies for the trail system.
The new underground reservoir is currently in phase one of construction and is the first of five planned reservoirs for the 608-acre Powell Butte Nature Park. The five reservoirs will help with anticipated increases in demand for water, and will offset the City’s plan to close five of its open reservoirs by 2020, three in Mount Tabor and two in Washington Park. The five new reservoirs, four of which will be 50-million gallons, while the other will be 20-million gallons, will accompany the lone 50-million gallon reservoir that already sits atop Powell Butte.
The PWB originally started this project in 1995 with the Powell Butte Master Plan, which proposed that a second reservoir would be built on Powell Butte by 2013. At that time, a Public Advisory Committee was created to steer the project and help map out a conditional use master plan. The group is comprised of recreational groups, environmental agencies, neighborhood associations and nearby homeowners.
The conditional use master plan was approved in 2003, which stated the park’s need for new buildings, parking lot improvements and trail improvements. The city then hired a group of consultants to put the advisory committee’s input into a plan. CH2M Hill, a Portland-based firm, is the lead consultant on the project, while they have subcontracted specific consulting services to Nevue Ngan landscape architects of Portland, the Wetlands Conservancy of Tualatin, Pacific Habitat Services of Wilsonville and Sea Research of Portland.
“One thing we heard over and over again was that we needed to put the focus back on the nature aspect of this nature park,” said Teresa Elliott, an engineer in charge of reservoirs at PWB. “So, we worked hard to find what specific wildlife areas within the park needed to be protected to maintain the natural integrity of the park.”
The point of contention within the project thus far has been working out the idea of expanding the wildlife area without giving up overall trail mileage. Something the people at Nevue Ngan Associates, the landscape architecture firm hired to design the trails, have been working at diligently.
At the recent open house, Nevue Ngan proposed a host of trail realignment options for three trails: Pioneer Orchard, Wildhorse and Mountain View. Plus, the firm introduced a possible new single-track trail, Upper Elderberry.
“This space is incredibly popular with a lot of different people, so we have to find out the best way to manage the natural qualities while still keeping it accessible to several different recreations,” said Kathleen Murrin, project supervisor with PP&R. “Thus far everyone has really come together and worked hard to make sacrifices so that this project can meet the needs of everyone.”
Several of the current trails either: run between two of these natural areas or run through an area that needs to be left alone in order for the park’s ecosystem to function properly. The problem with bisecting two natural areas, or compromising the ecosystem of the park, is that it makes it more difficult for wildlife to live in the area.
“These large areas where animals can live so close to the city is hard to come by,” said Murrin. “If we compromise that then we are taking away one of the key attractions of this park.”
At the expense of only a small amount of trail mileage, Nevue Ngan hopes to expand the natural area and improve the overall functionality of the trail system and the trails themselves.
While everyone agrees that wildlife should be protected on Powell Butte, some recreational groups believe rerouting or decommissioning specific trails could make the park overcrowded and dangerous with the expected usage increases that will come with these improvements.
“Powell Butte is by far the biggest mountain biking opportunity around the city,” said Dennis Veatch, director of the Northwest Trail Alliance, a mountain biking advocacy group in the area. “And once these trails are brought up to the standards that are being discussed, it is only going to become more popular.”
Veatch continued, “We are all for making the trails multi-use, but with increased attendance, the trails that we already have will be too crowded, let alone if some of them were to be decommissioned.”
One of the groups major concerns is the possibility of decommissioning the Pioneer Orchard trail, in order to expand the wildlife area to include drainageway and part of two wetlands. If this .75-mile trail was eliminated, not only would the most challenging mountain bike trail be lost, but also one of the longest trails for all park users.
“We are really excited that these trails are going to get the improvements that they deserve for everyone that uses them,” he said. “But we really hope that we don’t lose any of the trail capacity so that every recreation can enjoy the park in a safe environment.”
While not everyone agrees on the exact path of the trail system, everyone is excited for the trails to get the improvements that they deserve.
“The trails, to a large extent, were built throughout the years by the people that use them,” said Murrin. “While there efforts are much appreciated, we hope this project will make them even better so that they can be open longer with fewer environmental problems.”
The project team has been using environmental consultants and trail consultants in order to make trails that are more accessible, easier to maintain and more sustainable for every kind of use. Trails will receive improvements in drainage, adjustments in slope, widening of certain trails, smoothing out sharp corners, and improved surface materials and trailside vegetation.
The new buildings and parking lot improvements seem to have slightly less contention than the trail system, although that hasn’t been the case through this entire process.
“When we first took on the project and inherited the conditional use master plan there was just an outline of what had to be included and the general vicinity of where the buildings and parking lot had to be built,” said David Goodyke, landscape architect with Nevue Ngan. “What we found out when we went to the public is that the park users wanted these amenities, but wanted them fit in seamlessly with the park in order to keep the attention on its natural beauty as much as possible.”
After looking into the park’s history, the advisory committee decided the buildings and entry points should portray a farm motif. The 608-acre lot was originally an orchard and cattle grazing site for the Camp family in the 1880s.
The first way this will be accomplished is by giving the 162nd and Powell Street entrance, the only automobile entrance, a rural feel. The entryway won’t have bright yellow lines or big sidewalks. Instead, the entryway and parking loop will be outline by conifer trees and some of the park’s wetland vegetation.
“We really want the whole experience of being at the butte to come out as soon as you get out of your car,” said Goodyke. “We want the parking lot and entry road to be as non descript as possible so the focus stays on the butte.”
The interpretive center will house bathrooms, park information, an education center and a small amphitheatre. It will be built in a farmhouse style along with the caretaker’s residence and detached garage. Both buildings will be surrounded by trees in order to appear as non obtrusive as possible.
The major challenge as far as the buildings are concerned has been the 5,000 sq. ft. maintenance building that must sit within a 90,000 sq. ft. maintenance yard.
In order to keep the maintenance facility out of the way as much as possible, Nevue Ngan decided to move the building’s location to a slightly more non-descriptive lot than was originally laid out in the conditional use master plan. The building will now be built on a sunken lot to the Northeast of the parking lot and other buildings. The maintenance building will look like a giant barn, with only the roof being visible from the parking lot.
PP&R, the PWB and the various consulting groups hope to have a final recommendation for the advisory committee and the City by March of this year. Once that is approved the construction plan can be created and the work can be bid out.
