Braewood Hills 3rd Addition PUD (PDT 24-1 and ST 24-3) Page 14 of 14 <br />Standards Review Application: Written Statement <br />September 5, 2025 <br /> <br /> <br /> Schirmer Consulting, LLC · PO Box 10424, Eugene, OR 97440 · (541) 234-5108 <br />Landscape Architecture + Land Use Planning <br />0.25. The “openness ratio” is the cross-sectional area of the passage area under or within the structure <br />divided by the length of the stream segment it crosses over. For a box culvert, the openness ratio shall be <br />(height x width)/length. <br /> <br />(d) Culverts shall not substantially increase or decrease water depth or flow rate conditions upstream or <br />downstream from the culvert. <br /> <br />(e) The lower lip of all culverts shall meet the stream or channel bed at or below grade. <br /> <br />(f) Culverts shall be the minimum length practicable, and fill on top of the culvert shall have the minimum <br />footprint practicable. <br /> <br />Many of the criteria are not applicable. No culverts are proposed. <br /> <br />An existing 12-inch storm drain line, conveying runoff from the Goal 5 Resource to Videra Creek, will remain <br />intact beneath the proposed public road. The road design accommodates this utility without modification—no <br />culvert installation is required. <br /> <br />See detail entitled Culvert Section (even though no culvert is being proposed) on Sheet ST2.0. <br /> <br /> (11)Interpretive Facilities. <br /> <br />Not applicable. No interpretive facilities proposed. <br /> <br /> <br />If you have any questions or need additional clarification, please do not hesitate to call. We look forward to your <br />review and approval of this important housing project. <br /> <br />Sincerely, <br />Schirmer Consulting, LLC <br /> <br /> <br />Carol Schirmer <br />Principal <br /> <br /> <br />
