The site plan is too small for me to read elevations or follow grading contours, but you will need to insure positive finish grades which channel all surface water away from all sides of your house.

It appears that grading along the sides of the house may channel water against the house. Is this correct?

If so, you definitely want that corrected.

What is prompting you to seek improvement in your back yard? Do you not like what is planned so far?

Hi Mark I am just wanting it to appear
As large and spacious . I did not anticipate the house going as deep on the lot. Any advice you have please let me know .

Contact a local landscape architect that can stand on your site and advise. Are the adjacent lots for sale?

Hi mark too costly time acquire adjacent lot .
