Representative Industrial Projects include:

Brockway-Smith Company Manufacturing/Warehouse Facility, Saco, Maine:
This project included civil/site design of and permitting for a 297,000 sq. ft. building (6.81 acres), a 36-bay loading dock, 30 tractor-trailer storage spaces, parking for 324 vehicles, and vehicle parking facility. Analysis of stormwater quantity and quality associated with the creation of 15.17 acres of impervious area was a particularly challenging aspect of the project, given its location within the Goosefare Brook Watershed, which has been identified as a Non-Attainment Stream due to Urban Non-Point Source Pollution. Creation of an extended detention basin and infiltration system to manage stormwater was recognized by review authorities as a “good use of the land”. Permit approvals include an MeDEP Site Location of Development Act Permit, Natural Resources Protection Act Permit, Army Corps of Engineers Wetland Alteration Individual Permit, and an MDOT Traffic Movement Permit. Site development work alone is projected to exceed 4 million dollars.

Passenger Rail Platform, Saco, Maine:
This project was a fast track project and included the civil site design and permitting associated with the construction of a handicap accessible platform to service the re-establishment of Passenger Rail Service from Portland to Boston. Key site constraints included design of a handicap accessible route to the platform, development of an excavation plan within five feet of an active railway, and provisions for compliance with the Voluntary Response Action Plan (VRAP) developed for the project site due to the historical presence of hazardous materials. Coordination of electrical site lighting, a mechanical snow-melt system, and a structural canopy was required to adhere to the strict clearances dictated by Amtrak and the respective railroad entities. Permit approvals from the Saco Planning Board and Saco River Corridor Commission were secured as part of the site permitting.

Representative Municipal Projects include:

Rockland Avenue Sewer Separation Project, Portland, Maine:
This project included a hydrologic analysis of a 120-acre urban watershed and combined sewer system, in addition to a sanitary sewer system evaluation of the Rockland Avenue Sewer Service area. The studies reviewed the storm sewer system and future sewer separation requirements including the hydrologic evaluation of a 60” trunk storm sewer and 12” interceptor sewer. The final components of the project included the design of full depth roadway reconstruction (1600 feet), design of a new interceptor sewer (1600 feet) and design of a trunk storm sewer system ranging in size from 12” – 60” in diameter (2300 feet). Permitting and design of a stabilized outfall to coincide with the Capisic Pond Park was also a challenging aspect.

James Street Area Sewer Separation Project, Saco, Maine:
This project included a hydrologic analysis at a 38-acre urban watershed and combined sewer system, as well as a sanitary sewer system evaluation of the James Street Sewer Service Area. The project included the design of a trunk storm drain to service the complete sewer separation of the Hobson Lane combined sewer service area (38 acres) and conveyance of the 50 year design storm event. Additionally, a sanitary sewer was designed to replace a 24” x 36” brick sewer that was in existence since the 1880’s. The project included the design of 4900 feet of storm drain ranging from 12” – 42” in size and approximately 2850 feet of sanitary sewer. This project included permitting through the Saco River corridor commission, coordination with the Boston, Maine Railroad, application and receipt of a community black development growth and construction administration and project management at $1.2 million worth of construction.

Colonial Road Infrastructure Improvement Project, Portland, Maine:
This project included the design of 600 linear feet of 60” trunk storm drain, 8” sanitary sewer, catch basin replacement and underdrain installation. Key project elements included design to minimize impacts to existing water and gas mains.

Capisic Brook Flood Plan Management Study Re-evaluation, Portland, Maine:
Review and Analysis of a comprehensive Flood Plain Management Study of the 1683 acre Capisic Brook Watershed in Portland, Maine. The project included the hydrologic and hydraulic evaluation of improvements recommended as part of the original study as well as supplemental recommendations including culvert enlargements, dam modifications, channel widening and preliminary design of regional stormwater management facilities. This project involved hydrologic modeling (TR-20, HEC-HMS software) and hydraulic modeling (WSP2, HEC-RAS software) for review of impacts to the flood plain within the Capisic Brook Watershed.

University of Southern Maine, Ice Arena, Field House Project, Gorham, Maine:
This project included post permitting of the Gorham Campus since 1975, as well as permitting of the 66,000 square foot field house and 45,000 square foot Ice Arena projects. Development of a stormwater management plan included review of the 107-acre campus as well as a 328-acre offsite watershed. Review of the effects to Alden’s Pond as well as Tannery Brook included the design of a water quality wetpond for TSS removal.

Common, High & Wharf Street, Saco, Maine:
Design of infrastructure improvements which include 1,700 feet of roadway and sidewalk reconstruction, approximately 1,850 feet of sanitary sewer and separate storm drains. This project included the hydrologic evaluation of a 40-acre urban watershed and hydraulic analysis of existing combined & storm sewers within the watershed. Analysis of combined sewer areas and design of new storm drain systems to convey separated areas was performed using the XP-SWMM32 computer model developed for the City as part of their Combined Sewer Overflow Abatement Study. Additional project responsibilities include part time inspection and construction.

Capisic Brook Culvert Replacement, Portland, Maine:
This project included a hydraulic analysis of the existing and proposed culverts to be replaced at Brighton Avenue, Dennett Street and Violette Avenue crossings of Capisic Brook. The proposed culverts range from twin 6' x 10' box culverts to an 8' x 16' precast bridge culvert. The project required roadway reconstruction and relocation of a high pressure gas distribution main, two water mains, dual telephone duct banks and the relocation of the 24" West Side Interceptor Sewer.

Representative Commercial Projects include:

Skowhegan Savings Bank, Fairfield, Maine:
This project included civil site design and permitting for a 4000 square foot bank with multiple drive-thru lanes and 38 parking spaces to accommodate customers and staff. Siting of the project in the urban corridor was a challenging aspect to the project and required raising grade up to ten feet within the site to match abutting land uses. The project also involved elimination of on-street parking, evaluation of an offsite storm drain and local and state permitting.
