Colwood Golf Course: Phase II Development

Colwood Golf Course: Phase II Development
  • Type Engineer: Civil
  • Role Prime
  • Client Portland Parks and Recreation
  • Square feet 80,000

Following the City’s acquisition of the Colwood property, Emerio was hired to provide design engineering for PS&E construction documents for the re-development of civil improvements. Project scope included design of a separated pedestrian corridor to current PBOT standards, a creative stormwater solution, and parking lot improvements. Initial design for infiltration involved two dry wells, but a LIDA stormwater infiltration system and water quality swale was determined to be a more sustainable solution, engineered to the City’s 2014 Stormwater Management Manual. Parking lot improvements included reconfiguring the existing lot to current development standards and grading it to drain to the LIDA stormwater infiltration system. A sewer extension was designed, decomissioning the existing septic system and tying into the public sewer line. 

SE 122nd Ave Safety Improvements

  • Type Engineer: Civil
  • Role Subconsultant
  • Client Portland Bureau of Transportation

Emerio provided design services for PBOT's pedestrian safety improvement project along a heavily traveled commercial and residential corridor. As a bundled project, along four sections of SE 122nd Ave, Emerio designed enhanced pedestrian crossings including ADA ramp upgrades, stormwater infrastructure, grading, paving, striping, and signing for three Rectangular Rapid Flash Beacon (RRFB) crossings.  

SW Ventilation Facility and Capacity Improvements

SW Ventilation Facility and Capacity Improvements
  • Type Engineer: Civil
  • Role Subconsultant
  • Client Portland Bureau of Environmental Services
  • Square feet 10,000

Emerio Design provided civil design support on the project team to reduce sewer odors and increase the capacity of the Southwest Parallel Interceptor (SWPI) sewer system. Emerio’s task was to provide civil design, including grading and erosion control plans for the driveway and parking lot at the Ventilation Facility on the south side of SW Taylor’s Ferry Road, as well as design for the section of sewer pipeline extending from the facility to the adjacent manhole on SW Taylor’s Ferry Road.  

Continuing Care and Assisted Living Facility, Tualatin, OR

Continuing Care and Assisted Living Facility, Tualatin, OR
  • Type Engineer: Civil
  • Role Prime
  • Client Marquis Companies
  • Square feet 522,720

Emerio Design managed this redevelopment, from the demolished Tualatin Grade School into an 80-unit assisted living/54-bed skilled nursing senior care facility with supporting living, dining, health and community facilities for residents. Located on the corner of two major roads, SW Boones Ferry and SW Sagert, this project required extensive public works improvements, including half street improvement of SW Boones Ferry, ADA improvements, public water line extension along SW Boones Ferry, fire hydrant, water meter, utility poles, and lighting improvements.  Private onsite design included a parking lot, stormwater facilities, utilities, frontage improvements, grading, erosion control, and ADA improvements.  Design of 2 LIDA stormwater ponds for water quality and detention was a highlight of this project, as well as a water detention facility. A grading balance was determined early in the project to account for the five phases of the project. The master grading plan effectively eliminated the need for import and export of soil to the site.
