I got a call from Mark Foster saying he would have someone in the area that could make the change in the next few days but I have not heard anything since then. What Mark described in his message sounds like it might work for 627 Sparrow PI as an access to the side door. I did leave him a message that I would be expecting to see the drawing and certification from your engineer. I was at the site this morning and have a similar suggestion. Maybe leave the pad as is and pour a retaining wall around it with one step down to the back side. That way the soil supporting the pad can't wash away and it would lessen the drop for access to the rear of the lot. Just a suggestion. The biggest issue I noticed is that most of lots 17-20 and the backs of lots 21-24 all drain to the side lot swale along the side of 627 Sparrow PI (lot 25). Our design criteria only allows a maximum of three lots to drain to a swale between buildings. Usually it is the uphill two lots with a common lot line and then half of the lots adjacent to the swale. The existing grading does not comply with the approved grading plan. I have attached a portion of the grading plan. There is to be a similar swale between the buildings up hill from lot 25 which are lots 21-24. They also have a 6 foot drainage easement either side of the property lines for this drainage. Since these lots are mostly still under construction this can still be corrected. However if there are doors that access into the easements there will have to be encroachment permits for all of them and your engineer will need to certify the capacity of the swales. His certification for 627 Sparrow is not correct and if he had visited the site as is required he should have noticed it. Please have this corrected and if you have any questions feel free to call me.

The stability and capacity of the swale are the primary concerns that need to be addressed before we can consider issuing an encroachment permit or some sort of license to allow the exit pad from the door on the side of the home at 627 Sparrow PI. to remain in the easement. Jay Barber released the SW Eng hold on the CO so that the closing would not be delayed in good faith that you or your company would address the issue. This is Friday so I'm not expecting an immediate reply today but I wanted you to know that we are serious about this issue and expect a response next week. What I am expecting from you is certification from your engineer that the swale capacity and grades will allow the 100 year runoff as designed to pass through the swale and that the swale and access pad are stable and will not erode out from the flows. That can be addressed in a number of ways that Jay has discussed with you. Give me a call if you have questions.

Not only is it an encroachment but there is an existing erosion issue. I have contacted one of the City Attorneys and she is going to decide if it should be an standard encroachment permit filed with the County or some other document.
