This revision will keep all effected ridge heights below the 33 feet height limit. We will adjust our drawings and copy you on the revisions. Also included is the May 5, 2011 report prepared by HP Geotech addressing the debris flow conditions. Please let me know if you have any further questions. We look forward to getting started with construction. Sincerely, SEGERBERG, MAYHEW & ASSOCIATES, ARCHITECTS Kurt A. Segerberg, A.I.A. President KAS /Irt enc.

We previously conducted a subsoil study for design of foundations at the site and presented our findings in a report dated November 29, 2010, Job No. 110 364A. The proposed building footprint is similar to that shown in our previous report but has shifted slightly to the west and rotated slightly counterclockwise. The shift and rotation provides a little more room along the east side to work with grade changes and surface drainage. The grade change between the uphill Lot 2 and the subject site is proposed to be handled by a combination of retaining walls and fairly deep swales. We suggested to Glenn Palmer to revise the upper retaining wall of the spa area to be 1 foot above the drainage swale for freeboard. The driveway entrance for the uphill, primary unit has been shifted downhill to the west and the ground floor level has been raised somewhat which will provide at least one foot of fall from the building to the drainage pan of Westhaven Circle. Because potential debris flow impact to the lot will be from uphill across Westhaven Circle, we recommended that a civil engineer design the grading for the project. We understand that Alpine Engineering has been retained and is working to complete the grading plan started by the architect. The subject site is located in a moderate debris flow hazard area according to Town of Vail (2000). The potential flood impact to the property is fiom the drainage basin above the Glen Lyon Subdivision and flow across the alluvial fan upon which the property is located. Considering the property location in the lower part of the moderate hazard area, and that considerable development has occurred uphill in the subdivision, it appears that the potential impact to the property would be mainly from mud flood rather than debris flow. Mitigation of this type of flow can usually consist of on -site drainage features to route the mud flood flows down Westhaven Circle and around the east side of the lot by Tom Jaffe May 5, 2011 Page 2 earth berms, well defined swales and retaining structures. We recommend these features have a minimum depth or height of at least 2 feet and be designed to deflect flows downhill rather than intercept flows that could cause flow material to backup on the property. Based on these conditions and the rough grading plan provided by Glenn Palmer, in our opinion, the grading plan and building layout for the project can be designed such that the development will not increase the hazard to adjacent public or private properties including buildings, structures and road and utility right -of -ways. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - PAWLAK GE CHNICAL, INC. N- . P, I 4. a u ca 1 0 Steven L.

Dear Martin: Per your request, enclosed are four sets of revised construction documents. The most notable changes to the duplex have been the modifications to the site and grading plan and some slight adjustments to the primary and secondary floor elevations. We raised the entry level and upper level of the primary unit by l' -6 ". The primary entry drive was moved to the west to provide better drainage for this unit. The secondary unit was raised 6" and a site retention wall system is being designed for the east side of the secondary unit. The building footprint locations on the site remain the same. The revisions and responses to your April 14, 2011 letter are as follows: Architectural Comments: Heat tape will be used on all gutters and downspouts. See note on Sheet A1.0 snow fence retention devices will not be used. 2. Attic ventilation will be provided though gable roof at secondary unit. See Sheet A5.1. Five hundred (500) square feet will be ventilated with a minimum vent size of 1.6 square feet per 1203.2 IBC. 3. Attic access will be provided as shown on Sheet A3.4. Sheet Survey Attached are four stamped surveys as revised by Eagle Valley Engineering per Public Works request dated April 5, 2011. Sheet A2.0 The grading plan has been reviewed by Alpine Engineering and HP Geotechnical Inc. The plan has addressed the moderate debris hazard flow.
