Most clients need either a desktop screening or field wetland reconnaissance. If you need a full wetland delineation, Cattail Environmental can connect you with someone who can help you.
A records-based review of a parcel using National Wetlands Inventory mapping, NRCS hydric soils data, hydrography, LiDAR terrain, floodplain data, and the applicable county critical areas layers. You receive a short memo and a map set showing whether wetland or stream indicators are present, and where the risk sits on the parcel.
Best for: deciding whether to take a listing, pricing a property, or screening a parcel before making an offer.
Turnaround: typically about two business days.
What it is not: a site visit. Desktop review can miss features that mapping doesn't capture, and it cannot confirm the absence of a wetland.
An on-site walkover by a qualified professional, evaluating vegetation, soils, and hydrology indicators. You receive a written reconnaissance report with photographs, an annotated aerial, an assessment of likely wetland and stream presence, and a plain-language summary of the regulatory implications and probable next steps.
Best for: properties where a screening raised flags, where a buyer or lender is asking questions, or where you need to understand buildable area before committing.
Turnaround: typically within a week of the site visit.
What it is not: a formal wetland delineation, a wetland rating, or a Jurisdictional Determination. A reconnaissance tells you what is probably there. It does not establish legal boundaries and is not a substitute for agency review.
Reconnaissance is a professional's preliminary opinion on whether aquatic features are likely present. Fast and inexpensive. It informs decisions; it doesn't settle them.
Delineation is a formal, methodology-driven mapping of wetland boundaries performed to the Corps regional supplement, producing flagged boundaries and data forms. It's what you need when a permit application or critical areas review requires it.
Jurisdictional Determination is the Corps' own decision about whether a feature falls under federal authority. Only the Corps issues one.
Most people who think they need a delineation need a reconnaissance first, because the reconnaissance often answers the question for a fraction of the cost. Some genuinely need the delineation, and Cattail Environmental can point you in the right direction if you need one.
Permit navigation and application support for shellfish operations and aquatic lease holders. Including Section 401 Water Quality Certification submittals, aquatic lands lease coordination, U.S. Army Corps of Engineers coordination, and compliance calendars for operations with recurring obligations.
Best for: growers and shoreline operators who need someone tracking deadlines and preparing submittals so they don't have to.
GPS mapping of features and site conditions, georeferenced photo logs documenting conditions, features, and access, and stream channel observations including bankfull width, substrate, bank condition, and flow at the time of the visit. Findings come back as a clear, plain-language field report with mapping and photographs that are written to be handed to a lender, a planner, an attorney, or a contractor without translation.
Best for: documenting baseline conditions before a purchase or a project, building a record for a permit application, capturing conditions after a storm or a disturbance, or giving your engineer or attorney something concrete to work from.
What it is not: a boundary survey. GPS-mapped features are located for planning and documentation purposes and do not establish property lines or legal boundaries and that requires a licensed land surveyor. Stream observations describe conditions on the day of the visit and are not a regulatory stream typing determination.
Help choosing native and pollinator-friendly plants suited to your site and your part of the state, planting plans you can carry out yourself, hands-on installation, and mechanical removal of invasive plants. A back corner, a pasture edge, a whole yard, the aim is a planting that establishes and holds without constant intervention.
Best for: landowners who want more pollinators, birds, and native plants on their property and want to get the species and the placement right the first time instead of replanting in year three.
What it is not: mitigation or permit-required planting. This is voluntary stewardship work on ground you own. If an agency or county is requiring a planting as a condition of something, that carries its own design and monitoring standards and I'll point you to someone who handles it.
Sample collection and coordination of laboratory analysis for residential wells and municipal water, plus soil macronutrient testing. I handle the sampling protocol, chain of custody, and lab coordination, then walk you through what the numbers actually mean in plain language.
Best for: rural property buyers who need to know what's coming out of the well before closing, landowners troubleshooting water quality, and anyone planning plantings, pasture, or a garden who wants to know what the soil is working with.
What it is not: a health department determination of potability, and not a septic site evaluation or percolation test. Soil macronutrient results describe fertility, not suitability for a drainfield.
