Hello Cherri,
I figured making this table would help explain the impact. I built it based on some areas calculated by the architect. The
totals at the bottom are the Planned minus (-) Existing areas. The zone one had more area impacted than my original
estimate.
Zone 1 Zone 2 No grade Beyond Total
Planned
Deck 22 82.6 0 0 104.6
Screened Porch 173 135 0 308
Walkway 30 80 110
Existing
Patio 12 82 0 94
Current Deck 113 0 0 113
Additional impact 22 130.6 53 80 285.6

Hi Alvaro,
Thank you for getting your architect to calculate the areas that will be impacted in Zone 1 and 2 of the buffer. These
impacts must also be clearly depicted on the site plan. As I mentioned, you're building permit will be based on having
these impacts depicted accurately.
As for your driveway and the removal of part of it, I'd keep it simple at this point and not include that as part of this
application.

When I have the impacts so that I can understand what's going on, I'll send you the information for how to buy credits
for the Zone 1 impact. If the impact is small, it will be a nominal cost.

Hello Cherri,
I considered the area affected only for zone 2 as requested in the table. It is an estimate I did. Part of the screened
porch and the whole walkway are out of that zone. But, the city of Durham is considering that area as part of their
variance. I was hoping that a statement from DEQ would consider that as not impactful. Sorry I made things confusing
by mentioning work done outside of zone 2.
Regarding the small area affected by the deck in zone 1, it looks very small, I did not have a good way to estimate it.

I just requested my architect to calculate the area in zone 1 and to calculate how much is being added in zone 2 as
well. I will send this to you as soon as I get it.
As an additional observation. We just cut part of the driveway in front of the house. to put plants in it so there is more
depth in the facade. You can see it in one of the drawings. Should this gain in permeable area be included in the
calculations?
Best regards,

Hi Alvaro,
I've had a chance to review your application for your project at 3014 Elk Ridge Road and just need some assistance
interpreting what you've included as impacts. In the application you state that the current deck and patio footprint is
207 sq ft, and the planned screened porch and deck have a footprint of 408 sq ft. There's also a walkway with a 110
sq ft footprint. The Impact Table has 155 sq ft of impact in Zone 2, but when I subtract 207 from 408 and then add
110, 1 don't get 155 square feet. Also, I don't see the new walkway depicted on the site plan. In addition, it looks like
a portion of the new deck extends into Zone 1 of the buffer. That impact needs to be included in the Impact Table,
and it also requires mitigation. I can explain more about the mitigation requirement once I more clearly understand
what's going on with your site plan and impacts.
It's important to have everything clearly depicted on your site plan and application in order to get a building permit
from Durham for this project. Thank you for your assistance with this application.
