Mitigation Planting

Stormwater Management

Stormwater is one of the leading sources of pollution in Cape Cod’s wetlands, water supply, and waterways. CIE can assist property owners in incorporating sustainable stormwater infrastructure and management standards.

Nitrogen Credits

Adding bedrooms and increasing property values in nitrogen sensitive areas.

Using our in-depth knowledge of wetlands regulations and wastewater technology CIE has developed a turn-key package for adding bedrooms in nitrogen sensitive areas of Mashpee and Falmouth by utilizing property owners’ rights and little known regulations-A situation that would otherwise be impossible.

The limit on bedrooms able to be added is dependent on the area we have to work with. Typically, very small lots are restricted to 1-2 bedrooms. We can increase the property value of some of these small lots by 100’s of thousands of dollars through the nitrogen credits.

There is no other way to accomplish that and we are the only firm that provides this service.

Beach Nourishment

Cape Cod’s beaches are eroding at an alarming rate. Rock seawalls and breakwaters built to protect homes are, in some cases, actually stopping beach migration and starving downdrift shorelines of the sediment needed to replenish the shoreline system.

In many cases, development and infrastructure changes to our landscape have interrupted the natural movement of sand on Cape Cod. Rising sea levels and increased severity of wind, storm surge, and flooding intensify the problem.

One method for stabilization and shoreline protection is beach nourishment, which means dredging or taking sand from elsewhere and putting it back on the beach. CIE has a successful track record in the analysis, permitting, and execution of beach nourishment projects.

Flood Zone Determination

Often homeowners can get their property removed from FEMA’s Flood zone designation. CIE will perform an elevation study on your home and compare the location and elevation of the house to the flood plain requirements to determine if your home sits above the risk area.

Home Site Grading Plan

Site Grading

A grading plan establishes proper soil elevations around a home to prevent water from storms and irrigation from running back toward the home. Improper grading can cause moisture issues at the foundation wall, or saturate the soil next to the foundation causing hydrostatic pressure against the wall, which can cause foundation cracks, structural damage and even soil erosion.


For municipalities, dredging activities are used to maintain and ensure safe usage of our waterways for vessels. Coastal landowners often dredge to improve boat access to a private dock or bulkhead. The removal of mud and decomposed organic material from waterways can increase suitable shellfish habitat and promote improved water quality. When dredge areas are carefully selected and the project incorporates a robust shellfish seeding program, the end result can be a substantial net environmental benefit.

CIE works with municipalities and landowners to develop successful dredging strategies that eliminate impacts to our aquatic resources and wildlife. We will guide you through the very complex and lengthy permitting process and ensure that the project is a success. We also work with dredging contractors to conduct pre/post-dredge surveys utilizing our drone survey technology.

Hydrographic Mapping

Hydrographic surveying of the ocean floor depths and features is the foundation of any waterway project and is typically used in the design, permitting, and construction of piers and docks, marinas, and dredging projects.
