1. How long will construction last?

Construction begins mid summer 2013 and will last through fall of 2014. The project is divided into three phases to minimize the impact, the first phase beginning at A Street South.

2. Why is this project being done?

The existing 30-inch diameter Brookdale interceptor is nearing its capacity of 7 million gallons of wastewater per day. In addition, high concentrations of hydrogen sulfide gas from naturally occurring bacteria have corroded the inside of the pipe. Groundwater also infiltrates the sewer pipe, reducing its capacity to carry wastewater.

3. What will the construction consist of?

The best way to address capacity, corrosion, and groundwater issues is to replace the old pipes with a new, larger one. This project replaces existing pipes with a larger, 72-inch diameter interceptor pipe along Brookdale Road from Golden Given Road E. to A Street S. Shifting the interceptor north to 131st Street E. from 8th Avenue E./133rd Street E. places it in an area less affected by high groundwater. The new pipe is made of material more resistant to groundwater infiltration.

4. What are the traffic impacts during construction?

The project will be constructed in three phases to minimize traffic impacts. Local and emergency vehicle access will be maintained at all times. However, property owners and commuters should expect occasional delays. There may be intermittent road closures to through traffic. Any road closures and proposed detour routes will require approval by the County before implementation.

5. I live on the project route, are there any impacts to my property?

In most cases, the contractor will not impact your private property. In some cases, the contractor may need to enter the areas where a temporary permit was previously acquired to reconnect your side sewer to the sewer main.

6. How will I know what the “limits of construction” are for this project?

The limits of construction are within the County’s right-of-way. In preparation for construction of the project, County surveyors will stake the right-of-way for the project. These stakes are wood lathes with pink and yellow flagging. The staking will be completed for each phase, so you may not see the stakes in your immediate area depending on where you live along the construction corridor.

7. What are the hours of construction and will there be odors, noise or dust?

We do not expect significant odor or construction noise. The contractor is required to use a water truck to mitigate for any potential dust as a result of construction activities. Work is typically performed between 7 a.m. and 5 p.m.

8. Will my utilities or other services be interrupted during construction?

Some of the work may cause temporary interruptions in sewer service. The Contractor is required to provide notice 24 hours prior to any service interruption.

9. Are there impacts to access of emergency responders and mail delivery?

The contractor is required to maintain access for emergency vehicles and mail delivery.

10. Who is the project contractor?

The construction contract has been awarded to Northwest Cascade Inc.
