Invasive black-topped service roads form the backbone for our city park trail system. Is there an alternative?

The city plans to install a back-topped asphalt trail through the Leary heron rookery forest

12 foot black-topped road is planned for this new trail by the Leary Avenue heron rookery. Less invasive soft surface trails, as in the small picture on the right, would be more aesthetic and more forgiving of the trees -- especially trees remaining on the trail to control bicycle speeds. Water will be blocked off by impervious black-top, threatening these trees. The three small pictures are of ADA approved trails where narrow bicycle and wheelchair tires can be used. ADA crushed rock trails are pervious to rain, more eco-friendly and less envasive.

Less invasive, eco-friendly, ADA approved trails could be installed by this forest remnant but the city rejects this idea thinking: 1) bicycles, strollers, and wheelchairs need black-top surfaces and 2) grant money is not available. In the two Park's Commission meetings I've attended the Park's department never seriously evaluated the viability of eco-friendly crushed rock trails. Pervious, crushed rock trails will support wheels as narrow as a wheelchair. Several companies specialize in eco-friendly trails - a description of Enviroseal, Inc. trails is found on their Environseal website.

The Parks Dept. has an opportunity to install an ADA eco-friendly trail at Idlewood Park and this rookery, as beta sites. If we don't evaluate these trails soon all of our park trails under development and future park trails requiring a "backbone" will be paved over with asphalt. Is this what we want as Redmond pushes to Go Green?

Lisa Singer, city planner describes the trail route as:

"The trail through the woods will be a connection from the 520 bike trail and the Sammamish River trail northward to the transit center on NE 83rd St. The Northward extension of the bike lane will occur under the next phase of the project, which will build the 161st Ave NE connection. At the south end of 161st and the north end of this woods trail, we are constructing a plaza." Lisa Singer, Project Manager, Bear Creek Pkwy Extention

This trail is an excellent connector for circulating bicycle and pedestrian traffic away from busy downtown; though it is unfortunate 25 trees had to be removed. As you can see from the photo, Parks Dept. scattered a few trees on the trail to slow bicycle speeds and improve aesthetics. Nice touch.

(1) The heron rookery has been inactive with no colonies present for over 3 years. The heron you see in Redmond migrate from Issaquah rookeries to forage for food fish and small mammals. I hope the city will cooperate with Issaquah to protect our source of herons!

    We are able to sell factory direct and I am available for consultation on your project. We are able to make the surface hard like concrete if you’d like. In golf course installations, we have been using recycled concrete as the base and treating with our M-10+50 product. This will provide a hard wearing surface similar to poured concrete that is dust free, water proof, and durable for a minimum of five years. We have had horses use our trails without surface damage so I would imagine a bicycle would have no problems.

    If you would like a product sample and information sent to your attention, let me know and I will send it out.

  2. Using other than hard surface for this section of the trail is a bad decision. We can ride all the way from Seattle and other locations to this point and then with bicycle with street tires must dismount and push/carry it. Bad decision.
