EnviroVector performs fast and accurate wetland delineations to satisfy the requirements of Federal, State, and local permitting Agencies. Highly trained and experienced biologists perform rigorous scientific assessments to demarcate and document wetland boundaries. Detailed scientific data is collected on soils, vegetation, and hydrology to document primary and secondary wetland indicators. Wetland functions, including water storage, water quality, and habitat functions, are evaluated using the established scientific methodology and are documented using the standard scientific format. Wetland identification and delineation methodology is based on the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual and the 1997 Department of Ecology Wetland Identification and Delineation Manual as amended.
EnviroVector performs wetland and critical areas assessments during the feasibility phase of a potential project to assist in smart and successful land purchase and land use decisions. Land use consultation provides practical knowledge with direct application applied toward maximizing your land use investment and optimizing your land use potential. Existing critical areas databases including that of wetlands, soils, streams, flood zones, slopes, and fish use are researched to determine documented environmental regulatory constraints on a property. A field evaluation is performed to verify database information and to field locate potential environmental regulatory constraints that may limit land use plans.
EnviroVector prepares accurate Jurisdictional Determination (JD) reports that get results. Our reports are prepared as part of your permit package. Jurisdictional waters will be illustrated on drawings to scale. If federal jurisdiction is in question, EnviroVector will clearly label jurisdictional waters, based on the Federal definition. State Jurisdictional Waters will also be labeled and required regulatory buffers will be drawn and labeled. See EnviroVector CA for more detailed information on JD Reports.
We prepare mitigation plans to satisfy Federal, State, and local permit Agencies. Regulatory agencies may require the preparation of a mitigation plan to off-set unavoidable wetland or buffer impacts as part of a development project. Our goal is to optimize usable area through through responsible land use and through allowable wetland and buffer alternations that include wetland & buffer exemptions, buffer reduction, buffer averaging, wetland fill & replacement, and more. As such, usable area and land use intensity may be increased in accordance with Federal, State, and local land use regulations
Winter floods washout roads and damage property causing a disruption to daily life. Taking matters into your own hands could result in a violation of Federal, State, and local regulations, leading to fines and penalties. EnviroVector will guide you in the right direction, providing consultation to repair the damage legally and quickly. We will classify the stream, assess potential property damage, evaluate stream impacts, and design measures to repair your property, prevent future damage, and to protect and enhance the resource.
If wetland hydrology is not obvious or is in question, groundwater monitoring data can determine if an area is a wetland. Even if an area looks like a wetland, if there is no wetland hydrology as defined by the regulatory definition, then the area is not a wetland. Our studies apply powerful analytical tools for reliable results in determining if wetland hydrology is present. Wetland soils are typically saturated to the surface (within 12 inches) for more than 12.5 percent (approximately 21 days) of the (approximately 170 day) growing season in Western Washington. Groundwater monitoring data can determine wetland hydrology by evaluating the groundwater level and capillary fringe during the growing season. Our studies can determine the source of water whether it derives from groundwater interflow, hydrostatic pressure, local precipitation, or surface drainage. Hydrology studies also are applied to an analysis of septic feasibility.
