Traffic Advisory: Upcoming Nighttime Construction Work on SW Naito Parkway

 

Construction of a 36-inch steel water transmission pipe will start tonight, Tuesday January 3, 2012 at 9:00 PM at the intersection of SW Naito and Clay Street in downtown Portland. The work is being done by a contractor for the Portland Water Bureau. 

Work hours will be from 9:00 PM - 6:00 AM Sunday night through Friday morning for the next several weeks. Construction will start at SW Clay Street and proceed southbound along SW Naito Parkway.

Flaggers and traffic cones will direct motorists around the work zone. Some lane closures and delays should be expected. Motorists and bicyclists are encouraged to find alternate routes to avoid this work zone.

This work is part of the second phase of the Portland Water Bureau's Westside Header Project that will install another 5,000-feet of steel water mains to replace an existing critical but aging supply pipeline. Construction work on SW Naito Parkway began in September and is estimated to be completed by spring of 2012.

Traffic signals out of service on SW Naito Parkway

at intersections of SW Clay and SW Market Streets

Portland, OR  --  The traffic signals on SW Naito Parkway at the intersections of SW Clay Street and SW Market Street are not operating this morning. Early this morning, a construction crew working for the Portland Water Bureau cut through an unmarked power line to the signals.

The Portland Bureau of Transportation (PBOT) quickly dispatched a repair crew and was able to set the signal at SW Clay to flash 4-ways at the intersection. The crew was not able to temporarily repair the signal at SW Market Street, which is currently being controlled by six flaggers. 

PBOT estimates the repairs will be completed by 1:00 pm today.

The Portland Water Bureau is installing a 36-inch diameter steel water supply pipeline on SW Naito Parkway, from SW Clay Street to SW Caruthers Street. The night work -- 9:00 pm to 6:00 am -- on SW Naito will take several weeks to complete.

Motorists and bicyclists are encouraged to find alternate routes.

At SW Clay Street, traffic and pedestrian crossings are being controlled by six flaggers. The two southbound lanes on SW Naito Parkway are open. Traffic heading northbound is channeled into one lane through the construction zone. 

Motorists and bicyclists are encouraged to find alternate routes to avoid delays.

Bull Run Water Sampling Produces Rare Result

0 Comments | Add a Comment

Yesterday, the Portland Water Bureau (PWB) received preliminary laboratory results indicating the presence of Cryptosporidium in water samples from the Bull Run source collected on December 30, 2011. The lab results show that one Cryptosporidium oocyst was present in a sample collected at the raw water intake. A second oocyst was present in a sample collected from a location further upstream. Follow-up lab results received today from samples taken at the raw water intake on January 1st, 2012 and January 3rd, 2012 showed no further evidence of Cryptosporidium.

PWB has informed the Oregon Health Authority (OHA) and the Multnomah County Health Department of the preliminary lab results and neither agency has indicated a concern regarding any public health effects. No special precautions are necessary for Portland’s drinking water customers.

In the midst of a high volume sampling program, it is not unexpected that a small number of Cryptosporidium organisms would occasionally be found in untreated surface water. Wildlife is present in the watershed and can be a source of Cryptosporidium. Detections of Cryptosporidium in water from the Bull Run, however, are rare.

Today’s results are the first to indicate the presence of Cryptosporidium at the Bull Run raw water intake since 2002. Since the last detection of Cryptosporidium, PWB has collected over 725 samples totaling over 19,269 liters without finding it. PWB is now conducting increased monitoring at the raw water intake according to the terms identified in the Interim Sampling Plan which has been in effect since December 2010.     

PWB is arranging for additional analysis of the positive sample including DNA testing which may provide genotype information which could help PWB better understand and characterize the significance of this detection and indicate the possible animal source.

PWB will continue to implement the interim monitoring plan as it awaits a final decision from OHA regarding a potential variance to the treatment requirements of the federal Long Term 2 Enhanced Surface Water Treatment Rule (LT2). OHA has indicated that it intends to issue a final decision on the variance by the end of this month. Based on the comprehensive information and monitoring data compiled and transmitted by PWB in its variance request, we do not believe these isolated detections which have prompted no public health concerns affect the City’s underlying case for a variance.

PWB will continue to closely track and report Bull Run water quality monitoring results as we seek to understand and provide additional information about this rare, but not extraordinary event.
