Wetland regulations have recently become an obstacle for many developers, realtors and property owners who want to build on their property.  Due to the heightened importance of wetlands, many properties have been re-evaluated and cannot be filled without a permit. ET offers wetland services. Wetland Consulting Wetland regulations have recently become an obstacle for many developers, realtors and property owners who want to build on their property. Many of these parcels of property were not originally designated as wetlands when the property was originally purchased. Due to the heightened importance of wetlands, many properties have been re-evaluated and are now listed as containing considerable number of wetlands and cannot be filled without a permit. The wetland services ET offers are: Wetland Assessment Wetland Delineation Wetland Permitting Wetland Sequencing (Avoidance, Minimization and Replacement) Wetland Mitigation Plan Development Violation Compliance Wetland Construction Wetland Delineation Wetland Mitigation ET can assist the property owner by acting as an impartial third party for delineating the location, size and type of the wetlands on your property. Once the wetlands are delineated, a site map and final report are compiled outlining the vegetation type, soil classification, and groundwater depth discovered at the site. The report is reviewed with the client and options are presented which may allow the client to complete the project as inexpensively as possible. Classifying Soils Munsell Book Soil Identification Classifying Soils 1/2 If wetlands impacts are necessary to complete the project, ET can assist client’s wetland sequencing and mitigation. This wetland mitigation process provides a replacement plan that locates suitable property for wetland replacement or a wetland mitigation bank in your Service Area.

Extensive logging removed riparian trees throughout many watersheds, which has led to deteriorating streambanks. This continuous watershed instability negatively effects water temperature, sediment load and fish habitat.  ET utilizes its restoration approach to restore critical stream parameters. Stream Restoration Extensive logging removed riparian trees throughout many watersheds, which has led to deteriorating streambanks, a discharge of sediment and impacts to the stream channel. This continuous watershed instability negatively effects water temperature, sediment load and fish habitat. ET utilizes a restoration approach called Natural Channel Design to restore critical stream parameters. ET’s Natural Channel Design approach includes: Assessment and surveying of the stream using Natural Channel Design methodology. Collection survey data and biological data necessary to complete project permit applications and design a rehabilitation project. Monitoring the water temperature to select project site(s). Designing a stream restoration project to restore watershed function and stability. Restore the stream channel’s shape, dimension and profile. Enhance instream trout habitat by strategically positioning large woody debris, rock vanes and “J” hooks into the channel. Reconnect the channel to the floodplain. Create new floodplain benches and wetlands to retain water on the landscape. Raise the groundwater table. Stabilize streambanks with use of Toe Wood/Root Wads. Rehabilitate the riparian overhead tree canopy with native vegetative species. Stream Surveying and Restoration Design Restoration Construction Stream Surveying and Restoration Design ET uses the science-based Natural Channel Design methodology to assess and survey impacted stream reaches. This assessment/surveys method collects data from the impacted stream reach and compares it to several stable stream sections. All survey work is performed using a geomorphic trained Stream Specialist. Our assessment data collects stream width to depth ratios, floodplain elevation, erosion calculations, longitudinal profile, cross-section elevation and vegetation cover. The survey data is entered into a specialized stream restoration computer-based program to create plans and specifications that will restore impacted stream features. These restoration plans create the basis for the construction project by depicting channel shape, size and dimension reconfiguration, placement of structures, streambed depth, streambank elevation and any stream channel realignment. Another advantage of using ET for stream project designs is our projects are created to be self-maintaining due to our understanding of precise streambank elevations, channel shape and sediment transport. When the Natural Channel Design projects are properly designed, it results in a stable channel, that transports sediment, with an abundance of instream woody debris that creates scour pools and retained spawning gravels. Identified an Eroding Streambank during the Rapid Stream Assessment Cross-sectional Survey Longitudinal Survey Identified an Eroding Streambank during the Rapid Stream Assessment 1/3 Restoration Construction Historically large instream woody debris was prevalent in watersheds. This large wood created structure to the stream and created side channels, stabilize of banks, connected floodplains, retained spawning substrate and scoured sediment deposits. Today, much of this wood has been lost due to channelization and flooding, which has led to an increase in channel instability, bank erosion, and sediment discharge. To restore these stream impacts, ET imports large wood to rehabilitate the shape and pattern of the stream channel. Besides creating a stabilize and functioning channel, this substrate redirects current flow, creates deep scour pools, retains spawning gravels and stabilizes streambanks. This construction method that utilizes only natural materials, differs from traditional restoration methods that armor streambanks with riprap. The benefits of natural materials are the enhancement of instream habitat that support fish and a more aesthetic appeal.

Spill Prevention, Control and Countermeasures Spill Response Planning Storm Water Pollution Prevention Plans Health and Safety Services Spill Prevention, Control and Countermeasures (SPCC) Compliance Aboveground Storage Tank regulations are currently being enforced by the EPA that require most AST owners with an excess of 1,320 gallons of combined oil storage to have a Spill Prevention Control and Countermeasures (SPCC) plan. This plan examines the AST system piping, secondary containment, loading and unloading areas, facility drainage, surface water receptors, spill history, site security and training. After the site-specific SPCC plan is developed, a registered professional engineer is required to certify the plan. ET has the experience to tailor your SPCC plan to efficiently bring your AST/UST system to compliance.
