Commercial Projects
Kosco Harley Davidson Dealership – Kinnelon, NJ
This project involved the construction of a new motorcycle dealership and 125 car parking lot. Donohue Engineering prepared construction plans and provided construction inspection of the various site related construction. A NJDOT Highway Access Permit and NJDEP Freshwater Wetland and TWA Permits were required for this project. The project is located along Route 23 and required 12' high retaining walls to be constructed to meet existing grade behind the building. A new underground stormwater infiltration basin was designed and installed to accomodate the additional stormwater runoff.
Advance Auto Site Development – Fairlawn, NJ
This project involves the construction of two retail buildings, asphalt parking lot, site grading, lighting, and landscape design. Stormwater management design included the design of a large underground infiltration basin to accommodate the runoff from the asphalt parking lots. Services included planning board presentation, the preparation of site plans, municipal roadway design, stormwater management including stormwater quality, quantity and groundwater recharge analysis, and project phasing plans. Construction assistance during the installation was also provided of site drainage, curbing, sidewalks and grading.
Residential Projects
Kensington Estates Subdivision, Twp. of Jefferson, NJ
This project involves the preparation of subdivision plans for a 30 lot subdivision, including roadway geometry, stormwater management facilities and local roadway improvements. Donohue Engineering is responsible for the design and preparation of subdivision plans.
Eight Lot Residential Subdivision, Twp. of Jefferson, NJ
This project involved the design of proposed subdivision roadways to blend into the natural landscape of the project surroundings including the design of roadway geometry and stormwater drainage facilities.
Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
This project involved the redesign of proposed subdivision roadways to blend into the natural landscape of the project surroundings including the design of roadway geometry and stormwater drainage facilities. Donohue Engineering analyzed the previous roadway designs and prepared enhanced design documents.
Transportation Projects
Sunset Road Reconstruction, Pequannock, NJ. The project involved the full reconstruction of 1,350 linear feet of roadway including asphalt pavement, curbing, sidewalks and the upgrading of the existing stormwater drainage system.
Donohue Engineering provided full analysis, design and construction inspection for replacement of Structure No. 177 in the Township of West Milford, New Jersey. The project involved the full reconstruction of 33’ long box culvert, including stream hydraulic analysis, wetland and stream encroachment environmental permitting, wingwall and roadway reconstruction, asphalt pavement, curbing all adjacent to a high pressure gas main.
Stormwater Management
Mountain Creek Ski Resort, Vernon Valley, NJ
Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
The project involved a wide range of engineering and permitting services to the Solar developer, including wetlands delineation and permitting, geotechnical investigation, site civil and stormwater design, solar array layout, detailed design of parking canopy structures. The Project involved preparation of construction plans, stormwater management design, grading design, site layout and construction coordination. Storm water management design included the design of two above ground basins and three infiltration basins to accommodate proposed site modifications to 24 acres.

Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
This project involved the redesign of proposed subdivision roadways to blend into the natural landscape of the project surroundings, including the design of roadway geometry and stormwater drainage facilities. Two large above ground stormwater detention basins were designed to accomodate the development's increased runoff. Donohue Engineering analyzed the previous roadway designs and prepared enhanced design documents.
Residential Townhouse Project, Newton, NJ
Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
Residential Townhouse Project, Newton, NJ
Donohue Engineering provided Site Planning for this 60 Unit Townhouse Project. Several Roadways were designed to provide access to the residential units. The stormwater design included a new stormwater collection system and above ground detention basin design. Roof runoff was directed to underground infiltration basins. Construction inspection services were provided for this project.
Stream Hydrologic & Hydraulic Analysis
Donohue Engineering provided full analysis, design and construction inspection for replacement of Structure No. 177 in the Township of West Milford, New Jersey. The project involved the full reconstruction of 33’ long box culvert including stream hydraulic analysis, wetland and stream encroachment environmental permitting, wingwall and roadway reconstruction, asphalt pavement, curbing all adjacent to a high pressure gas main.
Lake Rickabear Dam Breach Analysis, Kinnelon, NJ. This project involved the complete hydrologic and hydraulic stream analysis for this 2.967 sq. miles drainage area and multiple dam breach project. The project analyzed the breach affects on the local roadways and on an existing residential community. The analysis determined the classification of the dam as “Significant Hazard Potential” or class II by using the ½ Probable Maximum Precipitation (17” rainfall) event. NJDEP Dam Safety provided agency review and acceptance of the Lake Rickabear Dam Breach Analysis.
Donohue Engineering provided site grading and stormwater management design for the Teterboro Airport Runway 1-19 Safety Improvements. The project will require the relocation of 1,300 l.f. of Redneck Avenue. The airport drainage basin involved presents challenges both environmentally and hydraulically due to existing C-1 wetlands and tidal flooding from the 10-year storm. Donohue Engineering was responsible for analyzing the proposed stormwater management impacts for compliance with New Jersey Stormwater Regulations due to the relocation.
Solar
Mountain Creek Ski Resort, Vernon Valley, NJ
The project involved a wide range of engineering and permitting services to the Solar Developer including site constraints mapping, wetlands delineation and permitting, local planning and permitting support, geotechnical investigation, site civil and stormwater design, solar array layout, detailed design of parking canopy structures and S
The project involved a wide range of engineering and permitting services to the Solar Developer including site constraints mapping, wetlands delineation and permitting, local planning and permitting support, geotechnical investigation, site civil and stormwater design, solar array layout, detailed design of parking canopy structures and Solar facility construction and site civil contractors. This project consists of developing three solar facilities (2 ground mount and 1 parking canopy systems). The Project involved obtaining Planning Board approval from Vernon Township, preparation of Site/Construction Plans, stormwater management design, grading design, site layout and construction coordination with the Town Engineer. Storm water management design included the design of two above ground basins and three infiltration basins to accommodate proposed site modifications to 24 acres.
