Keeping It Professional
Grading is not typically a DIY project. Many people may think that it couldn't be that difficult. Just a little smoothing out here and there should do the job. Then they go to a local equipment rental store and rent a skid loader. However, renting equipment and using equipment are two different things. It takes skill to operate just about any type of landscaping equipment properly.
Also, grading to ensure proper drainage involves more than just eyeballing it and driving equipment around the yard. A level is required to get a uniform slope across a landscape. This type of level is not the old manual bubble style that a carpenter would use on lumber. Landscapers use a laser level to calculate the correct slope across the entire yard.
