Cc: Schroeckenthaler, Scott 12-q.o� Subject: FW: 2891 Bible Camp Road Hi Roger, Mark Wohlferd of Design Shelters brought in a Zoning Permit application for a new house at 2891 Bible Camp Road (Section 9, Town of Dunn) today. Variance 3548 was granted for this lot and project in the Shoreland district on 08/28/2008, with the Condition "as requested by the Town of Dunn to keep surface water runoff generated on this property from going onto the adjacent properties" (see Minutes with packet on your desk). The Minutes also included a "Staff Note: Schutte or Lane will review the plans to verify compliance with the Zoning Ordinance, including maximum 30% lot coverage and minimum setback from OHWM, to assure satisfaction of Variance Condition before a Zoning Permit may be issued." I talked with Wohlferd a few weeks ago about the permitting process, gave him a copy of the Minutes, and asked him to provide me with all the documents for review, including a copy of the site plan for the Shoreland Erosion Control Permit. I use this to verify what's happening to runoff toward the neighbors' lots when the Town of Dunn asks for the above condition and the BOA includes it in the variance approval. Since I'll be gone until 01/05, I need to ask you and Scott to complete the necessary review, please, and issue the Zoning Permit if you believe the Condition has been met. Upon a very cursory review today, it seems the setbacks and lot coverage are OK. However, I have a question about how runoff is being controlled toward the south. Wohlferd argues that only new runoff should be "controlled." Ben at the Town of Dunn (with whom I have not communicated before re: the variance appeal or permit application) seems to echo that. However, it's been my experience that the Town of Dunn's Condition is intended to avert any changes to the runoff for neighbors of newly-developed lots. I'm not sure it's possible to quantify what part of the runoff was pre-existing and what part is new, so I have always looked for a berm or well-defined swale along the entire down-slope property line, as shown on a topo map. See the 12/18 email from Jason Tuggle at LCD regarding the same issue. The 12/18 response from Calkins Engineering indicates a "revised plan" was attached. However, the only Calkins"Proposed Grading Plan" that Wohlferd submitted today is dated 12-09-08 (no revision date). Wohlferd said there might be a "revised" site plan at Land Conservation, but didn't supply one. The 12/08 plan appears to me to show runoff toward the south to the west side of the garage on the neighboring property. In my opinion, that could 'funnel' part of the runoff from the new house directly toward the small house on the neighboring lot. For more information about pre-existing conditions (there is a smaller house at 2891 Bible camp Road now), please see the documentation in the Variance 3538 file. Do you think the grading plan as submitted will prevent runoff from adversely affecting the neighbor to the south? I don't think the decision should wait until I come back, so I'll be satisfied with whatever decision you make. Please contact Wohlferd directly. Scott said he'd process the permit once the "Condition" is met.
