KURTZ & ASSOCIATES, INC. STRUCTURAL CONSULTANTS 5012 County Road 154 Glenwood Springs, CO 8160 I MEMORANDUM Phone & Fax (970) 945 6305 To Garfield County Date: July 20, 2012 Attn: Building
and Planning Department Z-PSRe: Auxiliary Dwelling Unit:-:H25 Midland Avenue, Glenwood Springs, Garfield County, CO. Brian Kurtz, p, E, of Kurtz & Associates, Inc, has reviewed the structural
documents for the noted project and performed a structural inspection of the existing structure, The single story building measures, in plan, 40' -0" nOIth-to-south by 20' -0" east-to-west.
The framing system is constructed with light gage steel framing, The framing system utilizes three (3) interior steel frames which clear span 20' -0" east-to-west so that there are no
interior load bearing columns or walls, I understand that the foundation system is a shallow, frost protected system: It consists of a monolithic concrete slab-on-grade with thickened
ecjges, The thickened edges are 24" deep by 12" wide, Maximum soil bearing pressures occur at the columns supporting the interior frames, Based on a design snow load = 40 PSF, the soil
bearing, pressures are approximately 1200 PSF, It is my professional opinion that the foundation system is structurally adequate and appropriate for the building type, The building site
has been developed with the construction of a boulder retaining wall, The boulder wall is located uphill of the building: the toe of the boulder wall is approximately 4' -0'; from the
west wall of the building and the boulder wall varies in height from approximately 3'-0" to 4'-0", The building owner should be aware the soils in this area are know to be moisture sensitive
and prone to consolidation upon wetting, Soil consolid(!tion can lead to differential foundation settlement, and should be mitigated by minimizing site irrigation and controlling surface
moisture and roof runoff Specifically, olir office recommends that roof gutters and downspouts be installed, and roof runoff discharged downhill, and well away from the foundation, The
boulder retaining wall has the capacity to act as a diversion structure, The owner may also wish to consider II foundation drain for the boulder wall to capture and divert surface and
subsurface moisture which will tend to gravitate across the building footprint. If you have any further questions, feel free to call, Brian 1. Kurtz, P,E, Kurtz & Associates, Inc,
