Areas of Practice



Whether you're building your dream home, a vacation home, or a second unit for your in-laws, current regulations require a number of considerations be made. From roads to drainage, building pads to water systems, we provide the  guidance needed to get your permits.


If you're getting ready to develop, it's important to get the lay of the land and know all their is to know about your property. From topographic surveys, to boundary surveys, construction surveying to flood studies, our surveying team has a combined 40-years of experience. 


Commercial development presents a unique set of challenges in the North Bay region. Huffman's team of qualified professionals can help you meet all of the latest Low Impact Development and Accessibility requirements necessary for your project.     


Cost is typically the driving factor in all design decisions for municipal projects. We have experience working with large consultant teams to reduce costs, value engineer and keep your project under budget.


Disposing of your wastewater is the cornerstone of any rural development. From single family homes to large scale wineries, new-development or re-development, waste disposal is an increasingly regulated and costly part of your development plans. We have the experience to minimize those costs and simplify maintenance.

The latest regulations for On-site Wastewater Treatment & Erosion Control have but a strain on these sectors. We can help you meet the current codes and save you money while we do it.
