Sample Plot Plan

Sample Plot Plan

 

The engineered plot plan allows us to build quality, trouble-free homes.  They are used throughout the construction process to ensure local zoning requirements are met and to help the lot drain properly.  When done correctly, a plot plan is created that will minimize the cost of construction and the potential for basement moisture.  In this article we cover step 17 in our How to Build a Home blog series.

Civil Engineer Creates Plot Plan

Your civil engineer will help you create the plot plan for your new dream home.  This person has knowledge of local codes and restrictions to make sure your new home exceeds all requirements.  The engineered plot plan is designed for your specific house plan and lot to make sure they compliment each other.  Here are some of the things the civil engineer can do to hep you…

  • Design & Draw Plot Plan
  • Verify house will meet local zoning requirements
  • Dirt Balance – Perform a dirt calculation to determine if dirt will need to be hauled onto or off of your site

Elements of a Quality Plot Plan

  • Drainage – Shows how water will drain off of the property including any yard drains or swales.
  • Driveway – Minimize the slope on the driveway in cold weather climates to prevent dangerous conditions in icy weather;  locates driveway as far away from intersections for corner lots;  locates driveway away from utilities to allow for future access (without removing the driveway).
  • Utilities – Indicate utility locations on the plot plan, showing electric, water, and sewer.
  • House Location – Place the house on the lot to maximize natural lighting, meet zoning requirements and minimize costs to build by setting the elevation of the house correctly to minimize earth movement.
  • Easements – Shows locations on the lot that cannot be built on since future access may be needed for utilility repairs.
  • Lot Lines – Indicates lot lines for reference by the homeowner or contractors.  If you need info about choosing a lot for your dream home, check out our video, Choosing a Lot or Land.
  • Setback Lines – Shows restrictions for building by indicating zoning setback lines.
