Grading and Drainage
Homeowner Use and Maintenance Guidelines
The final grades around your home have been inspected and approved for proper drainage of your lot. Our surveyor completes a drainage certification and then the local building authorities as well as GOODIER BUILDERS inspect the site.
Drainage
Typically, the grade around your home should slope 1 foot in the first 10 feet, tapering to a
2 percent slope. In most cases, drainage swales do not follow property boundaries. Maintain the slopes around your home to permit the water to drain away from the home as rapidly as possible. This is essential to protect your foundation. Failure to do so can result in major structural damage and will void your warranty.
Roof Water
Do not remove the splash blocks or downspout extensions from under the downspouts. Keep these in place at all times, sloped so the water drains away from your home quickly.
Rototilling
Rototilling can significantly change drainage swales. You can minimize this by rototilling parallel to the swales rather than across them.
Settling
The area we excavated for your home's foundation was larger than the home to allow room to work. In addition, some trenching is necessary for installation of utility lines. Although we replaced and compacted the soil, it does not return to its original density. Some settling will occur, especially after prolonged or heavy rainfall or melting of large amounts of snow. Settling can continue for several years. Inspect the perimeter of your home regularly for signs of settling and fill settled areas as needed to maintain positive drainage.

GOODIER BUILDERS Limited Warranty
We established the final grade to ensure adequate drainage away from the home. Maintaining this drainage is your responsibility. If you alter the drainage pattern after closing, or if changes in drainage occur due to lack of maintenance, the limited warranty is void.
Backfill Settlement
Backfilled or excavated areas around the foundation and at utility trenches should not interfere with the drainage away from your home. If these areas settle during the first year, GOODIER BUILDERS will fill the areas one time. Subsequently, if settlement becomes severe during the first year, we will provide you with fill dirt to maintain positive drainage. You should keep the ground around the foundation tamped down against the foundation wall to avoid water getting in against the foundation.
Erosion
GOODIER BUILDERS is not responsible for weather-caused damage to unlandscaped yards after the final grade has been established or the closing date, whichever occurs last.
New Sod
New sod installation and the extra watering that accompanies it can cause temporary drainage problems, as can unusually severe weather conditions.
Recommendations
GOODIER BUILDERS documents the grades that exist at the time of delivery of your home or as soon thereafter as possible. The ground must be dry and free of frost to make these determinations. Once final grades are set, GOODIER BUILDERS will inspect drainage problems reported in writing during the warranty period, compare grades to those originally established, and advise you on corrective actions you might take.
Swales
GOODIER BUILDERS does not alter drainage patterns to suit individual landscape plans. Typically, a lot receives water from and passes water on to other lots, so changes in grade often affect adjacent or nearby lots. GOODIER BUILDERS advises against making such changes. After heavy rain or snow, water may stand in swales up to 48 hours.
Under Concrete
GOODIER BUILDERS will fill visible sunken areas under concrete during the first year.
Winter Grading
Due to weather conditions, especially during winter and early spring, the final grade may not have been established at the time of closing. We document the status of your grading at the time of delivery. When conditions permit, grading work will continue. Confirm that we have completed your grading before beginning landscaping.
