In today’s fast-paced development landscape, one unexpected challenge can stall a project before it even breaks ground: the presence of protected species. These animals play a crucial ecological role, and are often also heavily regulated. Encountering them on-site without prior planning can lead to delays, permitting issues, and unanticipated costs.

That’s where the Phase I Environmental Site Assessment (ESA) comes into play and why it’s smart to consider including a limited species screening as part of your initial ESA scope.

At Moran Consultants, we approach each Phase I ESA with a broad lens, identifying early indicators of potential environmental constraints, including signs that a site may support sensitive species. While a Phase I ESA is not a substitute for a biological or habitat survey, a limited visual screening can offer valuable insight early in the due diligence process.

What We Do During a Phase I ESA:

1. Conduct visual reconnaissance of the property, noting visible burrows, nests, or other features that may suggest protected wildlife activity.
2. Review environmental databases and public mapping tools to check for proximity to known critical habitats or protected zones.
3. Capture photographic documentation of notable site features observed during the visit.
4. Provide recommendations if further evaluations are required – such as a Habitat Assessment.

Why It Matters:

Including a limited species screening within your Phase I ESA scope can help you:

1. Flag the potential need for additional studies before development begins
2. Plan more effectively around agency requirements and permitting timelines
3. Avoid delays by identifying biological considerations during early-stage planning

Not All Sites Require a Habitat Assessment

Even when indicators suggest the possibility of sensitive habitat, a formal Habitat Assessment is not always required. Whether further evaluation is necessary depends on project specifics, such as the extent of planned land disturbance, the development type, and any applicable state or federal regulations. In many cases, if the property is already developed or excluded from critical zones, no further action may be needed.

Importantly, endangered species evaluations are not a required part of the ASTM E1527-21 Phase I ESA scope. However, a limited biological screening can be added as an optional scope item at the client’s request. This additional layer of review helps identify potential concerns early—so that developers, lenders, or project stakeholders can make informed decisions and consult qualified specialists as needed.

When to Consider a Species Screening:

1. The site is undeveloped or partially cleared.
2. It is near wetlands, preserves, or known conservations areas.
3. You are planning extensive land clearing or grading.
4. Local agencies or zoning boards have flagged environmental concerns.
5. You want to minimize risk before entering into a purchase or development agreement.
