Memorandum To: Paul McKee From: Stephen Stanley �S s�� %3 Re: Rucker Residence I have reviewed the geo-report and wetland delineation report submitted for the Rucker Residence and have the following comments and recommended conditions for the project are for your consideration: 1) Siting of House and Road. The submitted house plan and road do not conform to actual topographic conditions found onsite. When measuring the house footprint from the south property line, it was f�und to extend approximately 15 to 20 feet past the knoll (upon which the house is sited), into the reiatively broad terrace area south of the building site. This is of concem since the site plan shows the buildable envelope ending at the base of this knoll. However, if Figure I of the RZA-AGRA geo-study is examined it shows the building envelope at approximately the same distance (123 to 128 feet) from the southem property line measured on a north south bearing from where the 360 contour intersects the southem boundary. • These significant topographic conditions may represent the degree of ' sliding thet is occurring on the property. I would recommend, that a geo- tech from RZA-AGRA verify, prior to grading and excavation, that the staked location of the building footprint is within the building envelope. 2) RZA-AGRA shall review the building, retaining walls, and foundation plans to verify, in writing to the City, that they are consistent with the findings and standards set forth in their geo-tech report. 3) The applicant shall also submit the necessary erosion and drainage control plans recommended by the RZA-AGRA study. 4) Wetland Mitigation Plan. The wetland mitigation plan is acceptable. The applicant must submit a final planting and construction plan (including design for conveyance of roof top drainage to created wetland ar i calculations for sizing p; 'o deliver correct quantity and rate of wa�er to the�vetland) for the etland creation and bank restoration, with a cost estimate. An assurance bond for 90% of the total cost of wetland and bank restoration must be submitted to the City. d � ;;
