Development Project Photographs
The building shown is located on Badgers Island, in Kittery, Maine. The design involved tight grading and consideration of coastal zone rules and regulations	The project pictured involved a 30,000 sf expansion to existing Marston Elementary School with accompanying access drives, parking spaces, drainage infrastructure, utility connections, lighting and landscaping. The existing school and site is on a 17.4-acre parcel located at the end of Marston Way in Hampton, New Hampshire.	Shown in the photograph is an example of innovative leach field technology. Eljen drains are just one example of innovative technology that can be utilized to reduce construction costs and leach field area requirements.	The completed New Britain, Connecticut Shaw's Plaza. Mr. Eckman was a project engineer for this project along with several other Connecticut Shaw's sites, the Barrington, Rhode Island site,and the Bridgewater, Cohasset, Northbridge, and Revere Massachusetts sites whiule at Appledore Engineering, Inc.

Drainage Design Project Photographs

Depicted here is a large detention pond bounded on the left and front by a pre-cast block retaining wall with ornamental protective fencing. The stormwater control device was part of a twin-pond system with the first smaller pond serving as a fore bay to remove low flow contaminants. At the bottom of the photograph an emergency outlet with overflow risers and trash racks is visable.

Due to extreme grades over 30-feet of bedrock excavation were removed to facilitate construction of this Shaw's Supermarket Plaza. At the toe of the slope was a retention pond that also served as a rock catcher.

A two-pond stormwater control system. The first pond was sized to capture the first flush and remove contaminants from stormwater runoff. It is often called a fore bay and has a small outlet pipe with an elevated overflow weir for larger storm events.

Geotechnical Engineering Project Photographs
Retaining walls are often required as a result of the lack of ideal development parcels today. In this photograph a versa-lok retaining wall was used to match grades in this difficult slope transition.	The finished wall capped an existing slope with a vertical height of over 20-feet. Once vegetated it will not be visible which was one of the design considerations that lead to selection of the method.	The backyard that was once washed away has now been restored and as soon as spring comes will be fully vegetated. A protective fence was recommended to be placed along the top of the slope.
	How does a simple pylon sign create an interesting design challenge to an engineer? When design wind loads are applied to the surface area of a pylon sign a significant moment and force is applied to the footing. The unbalanced (eccentric load) was considered and a site-specific foundation design created.
