(EA) has been retained by Heath and Laura Pickett to provide a drainage memo to the City of Fort Collins regarding their home construction at 337 Wood Street, Fort Collins, CO. I visited the site on August 28, 2018 and observed the current site conditions. There is currently an existing residence on the site. Photos from the site visit are provided in Attachment A. It is EA's understanding that the current residence will be removed and a new residence constructed on the lot. The new residence has been design by Vaught Frye Larson Aronson architects, with the proposed grading plan provided by Crown Jade Design Engineering. The geotechnical report was provided by RMG Engineers (2018). The dra�age plal� provided by Crown Jade Design Engineering indicates the lot will be graded to drain to Wood Street. The water will be conveyed via swales along the north and south of the home. A swale across the backyard will be used to convey water to the swales located along the north a�id south lot lines. The grading plan is provided in Attaclunent B. The RMG Enguieers report states that a"well-defined swale sltould be cr•eated a rttini�nu�n S_feet fr-orn the foundation wall and sloped parallel with tlze wall with a rni�zimum slope of�2 percent. " Any runoff that does not infiltrate into the existing landscaping will flow to the street. This should prevent any additional runoff, froin the new construction, from draining to the alley or ajoing �roperties. Please call if you ]iave any questions or concerns.
