Date: 02/12/92 <br /> From: Ed Alverson CEWEERA - RIS1 <br /> To: Les Lyle CEWELAL - RIS1 <br /> Bob Hammitt CEWMJRH - RIS1 <br /> Gene Shutt CEWMEGS - RIS1 <br /> Dave Reinhard CEWTDNR - RIS1 <br /> Brant Williams CEWTBRW - RIS1 <br /> cc: Deborah Evans CEWEDSE - RIS1 <br /> Subject: Future Projects on W 18th at Willow.Creek <br /> I just wanted to let you all know that The Nature Conservancy would like to <br /> be informed ahead of time, and be able to provide some input, on any future <br /> projects along W 18th or Willow Creek Rd. where adjacent to the Willow Creek <br /> Natural Area. There has been quite a flurry of maintenance activity and bridge <br /> repair out there is the last few weeks, which I have only learned about after <br /> the fact. We would like to enure that any projects that are planned do not <br /> result in any detrimental impacts to the wetland and natural resource values <br /> of the site. I don't believe that there has been any major damage caused by <br /> the recent maintenance activity (and I'm really happy that all that trash was <br /> hauled away), but it is a sensitive area, and I'd like to advocate a cautious <br /> approach. For example, when Willow Creek was channelized downstream from <br /> W 18th, the elevation of the stream bed was lowered by several feet, creating <br /> a disequilibrium that has manifested itself as a head cut that is gradually <br /> moving upstreamon the south side of 18th. Eventually, this head cut could work <br /> its way upstream and greatly alter or eliminate the existing wetland habitats <br /> presently found along the creek, by lowering the water table. I would like <br /> have the opportunity to identify any potential problems that may come up in the <br /> future before work begins or resources have been committed to a particular plan <br /> of action. For example, I was told that the bridge over Willow Creek is <br /> planned to be replaced in 5 years, and I have hear rumors about upgrading <br /> W 18th and adding bike paths. The Nature Conservancy would like to have the <br /> opportunity to be involved in planning for these projects, and any others that <br /> come up. Thanks. <br /> Ed Alverson <br />
