Lee, I was able to sit down with Shawn(Director of Utilities)and Nick P(Water/Sewer Superintendent)to discuss your email.The following comments are in relation to the conceptual layout and provide general feedback as you continue to move into draft design. Design Feedback 1.Keep force main in City ROW as much as possible. 2.Limit amount of piping as much as possible,notlng there are constraints you are working around such as the electrical and gas mains,etc. 3.The City is ok with the wet well located on the east side of the property as present. 4.The City would like to limit the number of future manholes.The directive was to limit the amount of manholes vs placing multiple manholes in the BLVD space.This would require reconfiguration of the existing manholes in the Laurel Parkway,which may require regrading to achieve the desired flow results. 5.The City is ok utilizing the 30 foot easement to the south of the structure to maintain proper utility spacing requirements and future access. 6.The proposed Revised Manifold—Isometric drawing—Is the intent to split the flow between the 6-inch and 8-inch force main.A second closed gate valve may be necessary on the downstream side of the six-inch jockey pump feed for isolatlon.Based on our discussion it sounds like you anticipate using the 6—inch main during low flows and the 8-inch during peak periods. I was also able to discuss the downstream evaluation and model results with Shawn and Nick. Downstream Capacity analysis Director Determination 1.The anticipated flow associated with the Norton Ranch Lift station upgrades have adequate downstream capacity in the near-term to handle the expected Peak Flows at the future tle-in point on the 18-inch main within Cottonwood Road a.No downstream upgrades are required as part of these improvements. Please let us know if you any questions.

Shawn,Lance,and Nick, Lance was kind enough to jump on a quick screen share with me yesterday to look at the lift station site and the proposed configuration. Based on our chat,I prepared a conceptual layout to get additional feedback from everyone on this email so everyone is comfortable and I can move this conceptual plan forward into draft design documents. The attached exhibit shows our proposed configuration of the site and piping with the new wet well. A couple of notes on this site and configuration: • The proposed wet well location(east of the existing building)is the most constructable to avoid undermining the existing wet well,existing building,and a proposed expansion of the existing building. • The site is constrained to the south between the building and the property line. There is not sufficient space to accommodate the gravity main to the new wet well and the buried wet well underground piping while providing adequate separation distances from the existing property lines,the existing building, and between the buried piping and gravity main. o An existing sewer easement on the property to the south can help resolve this issue(see image below and attached easement). ..•��• .• .•�.•�.•�.•�.• .�.�.•�••�: II I I � �I R=170_00' L-269 I } — �=o"5`OF f�I �i I __ -._-- t�' �: c - � H=2.I , ' = VAUGHN DRIVE (60')��R�SEwER -- ; � , '�� Ii� � r�� - — � - EASEMENI ��`"� —_- � III�IIl�1T see oerna az sHeEr s- -_ _ _ •� _ —� _-- , r �j'u — _. — �\ r.. e � � � � �� —-- -_ - --- �P` `�_��r. � �,I� �°as�o�E i2o o _ - + —s< I ---- � \ T � i I 3o.00snNiraHvsEwEH � � I }�� '� EASEME�r —r� �o��.�o�sroR�,,��.,�v � i , ' IN SEEDETAILb2SHEETS � �AS�noLNT I 300f1'WIDEP�DESTRIAN& yi I' � , StED��ni�..'�SN_�i5 STORMSEWER I1 II EA52MENT I �L� SEE DETA14p�SHEEt 5 I � i�i�ll '�.

Proposed Manifolding I've also drafted a proposed manifold configuration for the building that would prevent the issues with the flow meters. Here's a few images of the existing configuration and the proposed configuration for reference.
