Dear Mr. Azhar,

Grading/Stormwater Plan Accepted
(Building Permit Released)
Accepted by: Dan Mogen
Date: 07/21/2020
The above referenced lot has historically drained from west to east. This lot has slopes ranging from
1.0% to 0.5% for a majority of the lot. The east side of the lot, adjacent to Martinez Street, does
drain towards the south.
The lot area is approximately 5750 square feet. The proposed impervious area will include 1803
square feet of house and 643 square feet of driveway/sidewalk for a total of 2446 square feet.
Attached is a drainage plan that includes drainage around the proposed new structures. This
drainage plan will conduct water away from the proposed structures and direct the drainage water in
the same direction as it has historically flowed. Swales will be cut in between the house and the
property lines on the north and south sides to direct a majority of the drainage to the east side. The
north and south side swales will drain across the turf and landscaping towards the east to Martinez
Street. We recommend that the new downspouts on the residence be installed to discharge
drainage water to the north or east so as to not direct roof drainage water at the adjacent properties.
The drainage recommendation for this lot will not have any adverse impacts on the adjacent lots.
Thank you for selecting CTL�THOMPSON for your engineering needs. When we can be of
additional service, please contact the undersigned.
Very truly yours,
CTL�THOMPSON, I
