Ecotone Inc. - Stream Restoration

  East Branch Winters Run - The construction documents prepared by Ecotone, Inc. and approved by the regulatory agencies, included grading plans, existing and proposed cross-sections, profiles, stream stabilization structure details, sediment and erosion control plans, geometry plan, bioengineering and wetland planting plans, specifications and a special provisions package. The landowner was compensated in return for recording a conservation easment on the restored wetland and stream acreage, as well as an access easement for long-term maintenance. Ecotone provided construction oversight during the entire construction period in the summer of 2003. The project restored 7 acres of high quality riparian wetlands and restored over 1,700 linear feet of the East Branch Winters Run.

Little Bennett Creek - The project was designed, permitted, constructed, and planted during the period between November 1998 and November 1999. The landowner was compensated in return for recording a conservation easment on the restored wetland and stream acreage. The project resulted in the restoration of 1,196 linear feet of first-order Use III trout stream, the creation of 3.98 acres of forested wetland, and the restoration/enhancement of 0.48 acre of degraded existing wetland. Fencing and other agricultural BMPs, including a hardened ford crossing of the stream for cattle and equipment, were installed to allow continued agricultural uses of surrounding areas while protecting the restored resources.  


  Booze Creek Urban Restoration - The project was successfully constructed by Ecotone in the winter of 2006. The increased capacity of the stream provided by the restoration design has resulted in decreased shear stress along streambank areas. The project held up well after experiencing several flow events exceeding the bankfull discharge shortly after construction was complete.

Hammonds Branch - Construction was completed in February of 2006. During construction, construction specialists from Ecotone’s construction staff alerted SHA and designer that existing conditions had changed dramatically from what had been depicted on the plans, and if the design were constructed as designed, a existing sanitary sewer running parallel to the stream would be exposed. Working with the project designers, Ecotone constructed the red line revisions to the plans resulting in the realignment of the ultimate stream channel. An additional rock vane and soil lifts were constructed at the base of the sanitary sewer to provide additional protection to the streambank.  

  Little Black Water - Ecotone completed the design to meet the short deadline in spring of 2008, including coordination with DNR, DSCD and the site engineer for an adjacent residential development to ensure that the proposed restored swamp runs would facilitate storm flows from proposed residential stormwater facilities. Construction of the first seven swamp runs was also completed within the short required time frame for completion, and all restoration grading was completed in November 2008. Ecotone worked closely with the project sponsors to make any required field changes and coordinate construction activities to reduce interference with ongoing crop farming on the site. During construction, Ecotone assisted DNR in installing a continuous water monitoring station along one of the swamp runs. Planting area layout, construction management, and as-built survey services were also completed by Ecotone.

Wolf Pit Creek - Ecotone functioned as the designer, permitting consultant, and general contractor for construction of the project. As part of the project, the fully entrenched degraded stream was relocated and elevated several feet from its original elevation in order to restore access and function to its floodplain. A sinuous C4 channel was constructed and stabilized with cross vane weirs, boulder vanes and wetland sodding. The adjacent wetland cells were sculpted to provide flood attenuation, water quality enhancement, and wildlife habitat within the floodplain areas. The project was successfully constructed in 2004 and has been monitored yearly by Ecotone.  

  Falling Spring: Headwaters - The source of Falling Spring, one of the preeminent spring creeks in the state Pennsylvania, had for many years been reduced to a stagnant pond with virtually no in-stream habitat. Initial biological surveys indicated very little quality habitat existed for trout or other aquatic organisms. The existing pond allowed the spring water to warm, creating a thermal problem for downstream reaches. Although the Falling Spring Greenway, Inc. had identified the reach for potential restoration, the pond had been left untouched for decades.

Falling Spring: Geisel Meadow -The project was constructed in the summer of 2006. A total of 900 linear feet of channel was restored to the Falling Spring in Geisel Meadow. Successes from the project were evident only days after construction was completed. Over the course of the past three years, annual monitoring surveys have indicated the design width and depth of the channel has been maintained. Resident trout have been utilizing the bankside lunker structures. Angling surveys indicate the reach fishes much more productively the prior to the project. Now thats the kind of outcome we like!
 

  Falling Springs: Chambersburg - This reach of Falling Spring, located with the town limits of Chambersburg, Pennsylvania, was plagued by wide slow flats with little or no in-stream habitat. Two landowners had asked the Falling Spring Chapter of Trout Unlimited for help in stabilizing the banks and improving habitat for trout. Although a spring creek, the reach had to handle stormwater runoff from extensive impervious surfaces draining the eastern third of the city of Chambersburg. Members of the chapter approached Ecotone to develop a restoration plan for the reach. Ecotone included the City of Chambersburg reach in a grant proposal they developed for the Falling Spring Greenway, Inc. which was submitted to Pennsylvania’s Growing Greener Program in 2002.
