Site Location and Project Description The subject site, The Arboretum at North Fontana, is approximately 453 acres, located north of Casa Grande Avenue, between Sierra Avenue and Citrus Avenue and the 15 Freeway. The site is located in the City of Fontana, San Bernardino County, California. (See Figure 1) The impact of the Arboretum project on the Citrus Avenue Sewer System has been studied down to the 210 Freeway. The entire site is tributary to the Citrus Avenue Sewer System. In addition, there are other offsite areas tributary to that same system. A total of 8 nodes were set to study the system. The following describes each areas considered for each node. (See Figure 2 in the back of the report showing each node location) The first node, node 10 is located at the intersection of Duncan Canyon Road and Citrus Avenue. The tributary areas to this node are the portion of the project site named "the Arboretum ", the office park located north of the Edison Utility Easement and 20 acres of commercial site north of the office park.

Purpose of Investigation The main goals of this sewer analysis were to: - Determine the flow going to the Citrus Avenue Sewer System - Determine whether the existing sewer on Citrus Avenue is sized adequately to accommodate the existing and proposed developments - Provide a conceptual estimate of pipe size and slope if there is a need for upgrade Those goals were attained by performing preliminary calculations and by consulting with the client and with other project team members.

Citrus Avenue Sewer Flow The primary purpose of this analysis is to determine if the Citrus Avenue Sewer would be sufficient to handle all the proposed and future developments that are tributary to the said existing sewer. On The previous version of this study was revised and extended with new tributary areas to ow each node. The revised tributary areas are shown on Figure 2 in the back of the report oft and on Figure 4 to 11. Node locations were also updated to represent more accurately the sewer system connection locations. See Appendix A for a detailed table showing peak ` flows at each node. am Wherever possible, the net acreages were taken to exclude all streets and other non -sewer ` generating areas. However, where no information in regards to net acreage was available, Oft the gross acreage was chosen for a more conservative output. In addition, for some existing residential developments where the actual number of dwelling units was known, ` the sewer generation was calculated based on the actual number of units rather than the .. acreage. The following table shows the generation rates at node 18 (the most downstream node) No shown on Figure 2, located just before the 210 Freeway.

Pipe Sizing Analysis The following are the equations that were used to verify the pipe capacity: an QpeakMGD = 2.5(Qgpd/l0 QpeakCFS =1.547 x QpeakMGD K'= Q n / (D ^8/3) * (SA 1/2) per Manning's Equation .. Flow Depth do by iteration of Manning's Equation Q= 1.486 / n* A* R ^(2/3) * S ^(1/2) low n = 0.013 A• rr The design slope is the average slope between the two nodes. OW All equations and average flows (see attached City of Fontana's Sewer Design Standard — � Table V -2 in Appendix C) used in the pipe sizing analysis are derived from the City of Fontana's Sewer Design Criteria and Standards. OW im Citrus Avenue Sewer System The existing 15 -inch pipe on Citrus Avenue down to Sierra Lakes Parkway would be able "„ to handle the Q generated by the proposed and future developments that are tributary to this sewer system. The flow accumulated at Sierra Lakes Parkway is approximately 3.2 MGD *` for a sewer of roughly 1,700 acres. The peak flow in the 21 inch pipe passed Sierra Lakes 6 Parkway where the slope is only 0.5% will exceed the design criteria but will not be flowing full (approximately 81% full). The velocity in the 21 inch line just before the 210 on Freeway on -ramp where the line slopes at 14.7% will be 19 fps. (see attached reference iu„ plan Dwg.

CONCLUSION Based upon our analysis, we conclude that estimated sewer generation could be handled by the existing sewer system on Citrus Avenue. There is no need to upgrade or alter the system for the proposed developments.

For purposes of this Master Plan, peak flows were computed based on projected !� average flow using the following formula: No PEAKING EO MULA ( ) pea k= 2.5 Qo.81 rte' The peak flow (0,,. and average flow (Q) are expressed in units of mgd. This 6M criteria was selected to provide adequate capacity to handle the peaking observed in IN the flows monitored for this study plus additional capacity for seasonal variations. aw Analysis of 18$0 flows to RP -3, done for CEMWD's RP -3 Master Plan (Ref. 11), confirmed the adequacy of an identical peaking formula to provide for peak flows imo generated within the study area at that time. A. 1 Pipe Design ON Three basic criteria of sewer pipe design were used in evaluating the City's existing W system and sizing of future master plan sewers; (1) depth of pipe, (2) slope and (3) O . depth of flow, *m The first criteria addresses both the minimum and maximum depth of pipe. In general, to a minimum cover over City sewers of 6 feet should be maintained. '' A default depth "' of 8 feet to invert was used for modeling new sewers where other constraints did not r�r govern. Depths to invert of up to a maximum of 20 feet were used as necessary to serve low lying areas. Deeper sewers, however, would be necessary in ALT-13 to run the regional interceptor sewer, against grade, back to RP -3. �r 0 ' VI -1 The second criteria addresses the minimum slope of the pipe. Slopes should be designed to ensure that sufficient velocities are developed at peak flow conditions to make the pipe self- cleaning. Adequate scouring is typically achieved at velocities of 1 2 feet per second or higher. in addition to slope, these velocities will vary depending on the condition of the pipe and depth of flow. Assuming the pipe is in average ■ condition (Mannings "n" = 0.013) and flowing at least half full at peak flows, slopes should equal or exceed those listed in Table iV -1. The third and last design criteria addresses the maximum allowable depth of flow. Due to the potential presence of waves on the surface of sewage flows and the uncertainty in projecting peak conditions, it is not desirable to design sewers for a maximum capacity condition. Hydraulically, this maximum is achieved when depth of flow is at a point between 90% and 100° of the diameter of the pipe. This maximum hydraulic capacity, however, is not typically sustainable as any variations in flow due to wave actions, etc. will fill the pipe. The maximum hydraulic capacity of a line, therefore, should be considered to occur at a depth to diameter ratio of 0.90 as shown in Figure VI -1. The maximum design capacity of new sewers, however, should be considerably lower to provide for uncertainties in projection of tributary land uses and flows. Depth to diameter ratios of 0.50 for 8 to 12 -inch sewers and 0.75 for larger sewers are recommended. Also, a minimum standard of 8- inches should be established for all City maintained gravity sewers. The maximum design depth to diameter ratios and minimum slope criteria are summarized in Table V1 -1 by pipe diameter. For purposes of this Master Plan, existing sewers with flows exceeding the design capacity but less than the maximum hydraulic capacity were considered MARGINAL. Existing sewers with flows exceeding the maximum hydraulic capacity were considered DEFICIENT and in need of relief or replacement, Future master plan facilities were sized to operate at or below their maximum design capacity.
