| 08/24/2015 | PAUL BAUGHMAN | ENGINEERING | REVIEW | Reqs Change | DATE: August 24, 2015 DUE DATE: September 9, 2015 SUBJECT: SFR south of High School Wash bank TO: Cypress Civil, Jeff Hunt, PE LOCATION: 813 East 8th Street REVIEWERS: Paul Baughman, PE, CFM ACTIVITY: T12CM01442 and T15OT01111 SUMMARY: Engineering Division of Planning and Development Services Department has received and reviewed the proposed SFR Plan Package, Drainage Report (Cypress Civil July 20, 2015). Engineering does not recommend approval of the SFR plan package at this time. The applicability of many of these comments is dependent on whether there is existing bank protection that removes the proposed structural location from the erosion hazard setback area. Any such bank protection, if it exists, should be photographed per comment 10 below with pictures included in the next submittal of the drainage report. Additional narrative should indicate the engineers opinion as to the protection afforded by such bank protection, if it exists, and what the subsequent impact on the erosion hazard area should be. The following items need to be addressed: 1) Per Chapter 26-8 (d) (2) Fill needs to extend 25' from edge of structure for a fill pad. Since the pad is only 50 feet wide it appears that a design alternative for a shorter distance may be required as provided by a civil engineer. Please dimension proposed distance from top of fill slope to structure on plan. 2) Per the Drainage Standards Manual section 8.5.10.1 superelevation needs to be analyzed and the finished floor elevation set based on developed conditions, superelevated flow depths. The current proposal to set the finished floor elevation based on existing conditions, unsuperelevated water surface elevations needs to be revised to reflect developed conditions. 3) Per Chapter 26, Section 7, 8 (4) and 8 (e) Erosion Hazard Setback needs to be established using equation 7.8 from the drainage standards manual. The radius of curvature (please show graphically and add this number to the channel report) of the channel will need to be determined to select the coefficient for use in equation 7.8. Per the Drainage Standards Manual section 7.4, item 1 the setback is to be measured from the top edge of the highest channel bank. If the setback is to be reduced below the limits established by equation 7.8 a soils investigation prepared by a state-registered professional Civil Engineer will need to be provided outlining the erosive properties of the area to be graded or disturbed. 4) Per section 6.6 and equation 6.3 of the Drainage Standards Manual, scour analysis needs to be performed if the structure is proposed in the erosion hazard setback area (EHS). 5) Per Chapter 26, Sections 5.2 (9) and 11.2 (h) the finished floor elevation shall be certified by a professional Civil Engineer or Land Surveyor such that it is shown to be at or above the regulatory flood plain elevation. 6) Per Chapter 26, Section 5.2 (11) all service facilities such as electrical, and heating equipment shall be at or above the regulatory floodplain elevation. Please add a general note to the plan. 7) Per Chapter 26, Section 5.2 (12) please provide slope protection, as designed by an engineer and concrete toe downs around fill pad where fill or structure has been placed in the erosion hazard setback area. 8) Per Chapter 29, Article 8 (Section 29-14) there is a study area measured 50' from the top of high school wash bank that may require additional analysis prior to development in this area. Please see Landscape and/or planning staff review comments for additional detail. If this lot existed on or before April 25, 1991, development of one (1) single-family residence may be exempt per Chapter 29-14 (b) (1). 9) Per Chapter 26, Section 11.2 (a) (1) and (2) a and b, please show proposed fill contours and a cross section of the proposed fill pad including the high school wash channel bottom, any existing or proposed bank protection, toe downs and the limits of the erosion hazard setback area. 10) Per Chapter 26, Section 11.2 (a) (2) b. please provide photographs of the adjacent channel upstream and downstream such that it can be ascertained whether bank protection currently exists. 11) Per Chapter 26, Section 11.2 (b) the floodplain use permit may be subject to conditions and restrictions designed to reduce or mitigate the potential damage or hazard to life or property resulting from development within the regulatory floodplain, floodway or erosion hazard areas. 12) Per Chapter 26, Section 11.2 (b) (6) please add a general note to the plan that indicates the applicant agrees to hold the city and its officials and agents, harmless and defend them from any and all claims for damages now and in the future relating to the use of the property sought to be developed by reason of flooding, flowage, erosion or damage caused by water, whether surface, flood or rainfall. 13) Please add easement recordation data for lot access through lot 3B.
