Why Does Your Construction Project Need a Grading Plan?

One of the first things you will notice about designing and building a new construction project is that a grading plan is required for permitting. Construction grading refers to leveling and backfilling the land as well as designing proper drainage for the property, with the plans developed by the project engineer and followed by an earthworks company. So why does your project need this service?


The main job of finish and rough grading Riverside CA companies in construction projects is channeling drainage away from structures and into a street. This protects the property from erosion and water damage, which can cause the foundation to weaken or the buildings to flood during rainstorms. When your engineer prepares the grading plan, he or she must consider how the changes in the slope of your property will affect those around it to ensure that all the drainage flows in the correct direction.


Grading can also include leveling, filling and backfilling a property, especially if it is outside of a developed city plan or includes a demolished property. Leveling changes the slope of the property to provide more space for building and proper drainage, it is common on hills where the slope angle may be too steep for the lot and building size. In this case, the civil engineer must make sure that the change in the slope of the new development does not change the way that older ones drain.

A grading plan is developed by a civil engineer and filed with other paperwork to get permits. A grading company then follows this plan to ensure that the site is properly leveled and that all affected drainage is directed towards a street and not a structure. If the drainage is not properly channeled, it can result in erosion and water damage to both the land and buildings.
