The Costs and Considerations When Constructing on a Tree-Filled Lot
Trees, especially mature ones, typically enhance the value and beauty of a lot for home construction. Many homebuyers want an idyllic setting for their dream home framed by a canopy of trees but this can add to the cost of the homebuilding process. A lack of trees is a telltale sign of cheap development. We all know it’s easier to clear the property of all trees than selectively keep trees in the process.
The extra cost for building on a tree-filled lot can be worth it as long as the homebuyer weighs all the costs and benefits associated with preserving the trees. Here’s a look at some issues to consider when purchasing a lot with trees.
Evaluate the Root System:
Evaluate the root systems located close to the home’s foundation. Mature trees on smaller properties have deeply entrenched roots that can affect the foundation of a home. If the lot is being redeveloped and an existing structure is torn down to make way for a new home, the existing root structure may have to be removed thus killing existing trees. If the lot is being cleared for construction, it’s important to avoid placing the foundation on or near an existing root system that can grow into the pipes and the underground infrastructure over time.
Consider the Treetop Canopy:
The logistics can be more complicated thereby adding to the overall cost of construction. Construction equipment also can damage the existing trees.
Consult with City & County About Drainage:
Consult with City and County authorities about drainage requirements. Consider the relationship between the trees and drainage. A common oversight when attempting to keep the trees during construction is the failure to understand the relationship between the trees and the site’s drainage. The drainage design is one of the most important elements of home site development. It is critical to check drainage requirements and finished floor elevations for the lot with both city and county authorities. This must happen prior to making the decision of which trees to preserve.
City and county engineers create the master plan of a development. They determine how a piece of property must drain and the soil height requirement to build on. The level of the soil is known as the grade elevation. It plays a critical role in conserving the existing trees on a lot. Here’s why: If the city or county requires a higher soil grade elevation than what’s in existence, the builder must bring in fill or extra dirt. This extra soil can smother tree roots effectively killing them. If the city or county requires a lower soil grade elevation, then the builder must remove soil, which can expose tree roots killing them as well. Sometimes the city or county will require shallow rainwater retention ponds on site that can affect the tree root system on the property.
The smaller the lot, the more critical are the abovementioned factors in the construction process. For more money-saving new construction tips and design ideas, subscribe to the video series, Trade Secrets, available on YouTube.
