4 May 15,26 l'l,lllnin;.: Andrew Seiger, P.E. Pima County Regional Flood Control District 21 North Stone Avenue, Fourth Floor Tucson, Arizona 857 I :'l!n1 ~in;.: RE: Dear Andy: Response to Review Comments (April17, 26)3rd Submittal Addendum to Existing Conditions Drainage Assessment for New Tucson Unit 3 SR 5165 I. Previously Addressed. 2. Addressed.. l'luo~w.l:2li '{I!LH\1HI LJli,Jil inloll IJriJarwnl'ino J ring.i IJIII l'h wrji\ 3. Partially Addressed: The provided information is insufficient to demonstrate that flow split will not occur. a. Please provide road elevation data which shows that Slate Drive is sufficiently elevated to return the right overbank (ROB) flows to the Wash B channel. RESPONSE: Slate drive is not sufficiently elevated to return ROB flows to the Wash B channel. Therefore, a "Diversion Channel" will be designed parallel to the existing platted channel in order to provide additional conveyance which will contain and return the ROB flows to the Wash B channel. A 67' Drainage easement on Lots: 3, 4, and 7 has been prepared for recordation. A Floodplain Use Permit will be required in order to construct said Diversion Channel. b. It appears that ROB flow will extend to Atrisco Drive. If so, please show the floodplain extending to Atrisco Drive. RESPONSE: The hydraulic section 14 for A/risco Drive has been adjusted to reflect the actual road profile; the road has sufficient elevation to return the ROB flows to the Wash B channel. Page I of3

5 Urban Engineering 4. c. If breakout flow does not flow across Slate Drive, and if Atrisco Drive is not raised high enough to return the right overbank (ROB) flows to the Wash B channel, then it appears from the contour information presented on Figure 2 that the ROB flow evident on hydraulic section 15 will continue to flow in the ROB of hydraulic cross sections 7 through 14. If this is the case, and if this possibly isolated flow path is regulatory, please expand the floodplain limits to include these ROB flows. RESPONSE: Gerardo Calza, Urban Engineering and Andy Seiger, Pima County conducted a walkthrough inspection on May 1, 26 of the subject area. It was confirmed that Atrisco Drive is sufficiently elevated to return ROB flows to the Wash B channel. d. If modeling with elevation data on Slate Drive does not show that the road will prevent the breakout flow, and this flow is found to be regulatory, then please provide a separate model reach to follow this breakout flow downstream. RESPONSE: Please refer to the response for Item 3. a above. Previously Addressed Addressed. Previously Addressed. Addressed. Previously Addressed. Previously Addressed. Addressed. Addressed.
