Clinton Green Street and Sewer Construction Update: April 10, 2015

As part of the Tabor to the River Program, Environmental Services continues construction on the Clinton Green Street and Sewer Project. This project will replace 3,800 feet of sewer pipe installed over 100 years ago, construct 24 green street planters and add two blocks of pervious paving. These improvements will protect public health, property and the environment, and reduce the possibility of sewage releases into streets, homes and businesses.

DEVELOPMENTS OF NOTE

Pervious paving on SE Ivon Street between 20th and 21st avenues and between 21st and 22nd avenues will begin next week

  • Beginning Tuesday, April 14, 2015, SE Ivon Street between 21st and 22nd avenues will be closed to all traffic, 24 hours a day, for about four weeks.
  • Beginning Monday, April 20, 2015, SE Ivon Street between 20th and 21st avenues will be closed to all traffic, 24 hours a day, for about four weeks.
  • Crews will excavate the existing asphalt, prepare the road for paving, and repave with pervious asphalt. Excavation and preparation is expected to take up to three weeks. Pervious paving will then be applied and allowed to cure (or harden) for up to four days before re-opening the road to traffic.
  • The construction start dates are firmly set, however, work may be postponed due to wet weather and rescheduled on short notice.
  • Over the course of this work, traffic will be delayed periodically on SE 20th and SE 22nd between SE Division and Clinton streets to allow equipment to maneuver safely.

CONSTRUCTION SCHEDULE:

Below is the estimated construction schedule for this week and next week. Please be aware that this schedule is subject to change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

Week of April 13

  • SE Taggart (at 30th Avenue) – lateral sewer pipe construction
  • SE Ivon Street (21st Avenue to 22nd Avenue) – preparation for pervious paving

Week of April 20

  • SE Ivon Street (21st Avenue to 22nd Avenue) – preparation for pervious paving
  • SE Ivon Street (20th Avenue to 21st Avenue) – preparation for pervious paving

WHAT TO EXPECT DURING CONSTRUCTION

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • Please stay clear of all construction activities and keep children, pets and vehicles out of construction areas.
  • Traffic control signs are in place. The contractor maintains local access, but you should expect delays. Construction activities may impact normal use of your driveway.
  • On-street parking in or near the work area may be limited. Please observe the “no parking” signs.
  • Equipment and materials may be stored on nearby streets overnight.
  • There may be periods of inactivity between construction phases ranging from a few days to a few weeks.

DEVELOPMENTS OF NOTE

  • There will be continuous construction from 8:00 p.m. Friday, April 24 to 6:00 a.m. Monday, April 27. Detours will be in place during this weekend construction to allow work crews to install one of two, 120 inch manholes planned. The weekend work is weather dependent and may be rescheduled. The contractor also anticipates working the same hours on the weekend of May 1 through May 4.
  • Traffic will be reduced to one southbound lane with flaggers controlling traffic. The city may close Taylors Ferry Road if construction makes vehicle passage unsafe. Please plan to use an alternate route.
  • Last week work crews found some five-foot diameter rock boulders and larger. See photos on website.
  • It will take additional equipment to break up and dispose of this rock.
  • The contractor is using a large mechanical hammer to crush thick asphalt for disposal and clear the way for trench excavation.
  • Placement of 48-inch manholes will continue.

WHAT WE’VE HEARD FROM YOU

  • Limit speeds to 30 mph when driving near the work zone during all hours, due to steel plates and temporary pavement.
  • Temporary pavement is laid each night. The contractor will permanently pave the trench at the end of the project.
  • Please note that night work closes SW Taylors Ferry Road with no local access beginning at the east entrance on SW Macadam to just north of Riverview Abbey Funeral Home and River View Cemetery. Both businesses will remain accessible during construction.
  • Please email questions or concerns to Ashley Tjaden or call 503-823-5281.

CONSTRUCTION METHODS

The contractor is using both open trench construction and cured-in-place pipe repair. You can find more information about sewer construction methods at www.portlandoregon.gov/bes/methods. The contractor will use excavators to saw cut pavement, and bypass pumps to move sewage around the work sites and to circulate steam through sewer pipes to cure the liner. The contractor may also use utility trucks, backhoe, and lights during night work hours.
