Shoreline Stabilization & Sand Dune Permitting

The jagged coast of Maine measures over 4,500 miles.  Some of it encompasses beautiful sandy beaches, tidal waterways as well as rock lined shores.  WEA has developed a niche, assisting homeowners in protecting their coastal properties.  This complex and fragile environment provide a challenge to develop the protection system that will best serve the subject property.  WEA will analyze each site for its particular conditions and based on the factors involved will develop a system that will protect the property, while providing a solution that can be permitted through local state and federal permitting processes.

Our team has extensive experience designing projects to limit shoreline erosion and the effects of human activities. We use natural (living shoreline) and structural methods of stabilization to ensure a functional, yet aesthetic, results. Our site analysis includes wave analysis, flood analysis and overturning as is necessary.  We will prepare a feasibility study detailing our recommendations, estimated costs and time frame for completion. To further streamline the process for our clients, we can also handle the bidding process and construction oversight.

Most shoreline stabilization or restoration projects require a permit from the local municipality, the state of Maine or the federal Army Corps of Engineers. The permitting process sometimes includes all three. The licensed, professional engineers at Walsh Engineering Associates, Inc. have developed strong relationships and successfully worked with each of these agencies. Our designs will be developed taking into consideration the permitting requirements and will prepare all required permits and details required for your permit application; we will also handle all permitting correspondence.

One of the most highly regulated areas, design around the fragile dune system complex provides challenges for our clientele.  WEA has developed a system which provides due diligence and concept designs that allow clients to make decisions based on their particular circumstance.

Stormwater Design

Our engineers provide stormwater analysis and design services for a variety of projects including stormwater treatment design, stormwater quantity calculations, culvert and stormwater system designs to meet requirements of Local and State regulatory requirements.   The New England States have some of most stringent stormwater management regulations and creative solutions have become a requirement for engineers.  WEA employs all available technology for the stormwater systems, including LID/Green infrastructure, pervious pavements and natural systems such as wetlands to treat stormwater from site development.  All of our systems are designed to be cost effective while achieving the requirement of regulatory community.

For Industrial clients WEA completes stormwater sampling and monitoring, design for compliance  and permitting services to comply with EPA NPDES requirements.  Each industrial facility is different and requires a unique solution to their particular facility.  WEA has the expertise and knowledge to solve most complex industrial stormwater issues.

Our business offers many types of civil engineering services for individual customers and large companies, and while performing a culvert analysis, our experts can determine the condition of a structure, examine stormwater in a specific area, create a culvert replacement design, evaluate repairs that a culvert may need and develop milestones for contractors. Moreover, we commonly study the flow of water in numerous areas and determine the amount of liquid that specific conduits can handle.
