Eight miles of Echo Lake streets to be resurfaced

Do you live on one of the Echo Lake neighborhood streets marked in purple on the map? If you do, your street will be resurfaced next month, as part of Shoreline's street maintenance program.

Public Works will use a process called "Chip-seal" or "Bituminous Surface Treatment" (BST). Chip-seal has been used in Mountlake Terrace for years, but this is the first time for Shoreline.

Shoreline originally started resurfacing streets with asphalt, which creates a very smooth surface. It is also extremely expensive, and the original project had some difficulties with the asphalt peeling.

BST is very durable and inexpensive compared to asphalt. Jesus Sanchez, Director of Operations in the Public Works department, told Echo Lake residents at a public meeting in May, that one mile of asphalt was about the same cost as eight to ten miles of BST.

Public Works has been working with a consultant who has national expertise in BST. Contractors have been lined up. The City is waiting for hot weather. The BST process they have chosen requires three layers of material, with a curing period of 5-7 days between the second and third coat. The hotter the weather, the faster the new surface will cure.

Residents reminded the staff about the August 2 Night Out Against Crime block parties and staff promised that the work would take place after that date.

In response to questions, Sanchez said that residents would be notified street by street and given about a week's notice of work to be done.

Residents need to cut back all vegetation on their property which would be in the path of the trucks when the bed is up - typically a height of 13 feet.

Residents need to plan to avoid driving on the new surface until the traffic revision signs are removed.

Public Works wants to know about any imperfections in the streets, so they can be repaired before the new surface goes on. (See article). Public Works staff are surveying the streets but they want to make sure they haven't missed anything.

There is a set of questions and answers on the City street maintenance website.

Some streets in Echo Lake are not being resurfaced now because there is other work planned for them.  Many streets to the east of 5th Ave NE were resurfaced with asphalt under the first resurfacing project.
