Wetlands

Wetlands contain diverse and productive ecosystems that support a multitude of species. With the recognition of the value of these ecosystems, laws are in place to protect and restore impacts on these resources in the face of land development.

At Larson Design Group, we understand the regulations that protect these ecosystems. Through state-of-the-art approaches, Low Impact Development (LID), and environmentally friendly designs, we are able to effectively develop clients’ projects.

Whether you are planning a residential development, constructing a utility line, replacing a bridge, or restoring a stream corridor, LDG’s environmental specialists are fluent in the challenges that arise when proposed project activities interact with the natural environment.Services

Stream Restoration/Flood Protection

Environmental and Ecological Services

 

Stream systems and their associated flood plains are highly complex ecosystems impacted by land development and encroachments. It’s important to maintain the interconnectivity of a stream and its floodplain in order to support its ecological functions. Often, these resources are affected through channelization, reduced riparian buffers, agricultural processes, land development, transportation/utility corridors, and destructive natural processes such as flooding.

LDG assesses stream and riparian restorations with a holistic approach that varies from structural designs and channel modifications to realignments and restoring stream reaches with natural designs. Through our innovative practices, we prevent and minimize flooding, preserve natural floodplains, improve water quality, maintain ecological functions, restore healthy habitats for aquatic life, and reduce overall impact on infrastructure such as roads, buildings, sewer lines, and bridges.

Permitting

Stream and wetland regulations are ever changing; they vary widely from state to state and even from county to county. It can be difficult to understand the parameters a specific permit requires and which permit to use when.

Permitting a project can be done effectively and cost efficiently through appropriate avoidance and minimization measures. When completed through LDG’s planning and permitting process, clients see increased approvals, decreased delays, and reduced penalties associated with their projects. LDG handles complex projects and assists in navigating the permitting process through innovative and well-developed processes that will keep your project on budget and on time.

LDG has offices covering several states, each of which has a wide array of regulations. Our experienced environmental specialists and planners work closely with clients and regulators to develop project plans and permit packages tailored to specific needs and budgets, no matter the location, size, or complexity.
