SR-6-D (86) JUN 2 9 1999 (oD EPWM:CP:CP F IEPWMIADMINIWPDOCSISTAFFRPnwlrgarden wpd Council Meeting: June 29,1999 Santa MOnica, California TO: Mayor and City Council FROM City Staff SUBJECT: Recommendation to Authorize the City Manager to Negotiate and Execute a Modification to the Sewage and Water Conservation Comphance Agreement with Water Garden Phase I and II to Require Use of Reclaimed Stormwater In Lieu of Reclaimed Wastewater for Non-Potable Extenor and Intenor Water Uses INTRODUCTION This report recommends that the City Council authorize the City Manager to negotiate and execute a modification to the Sewage and Water Conservation Compliance Agreement with Water Garden Phase I and II to reqUire the use of reclaimed water from the City's Dry Weather Runoff Reclamation Facility (DWRRF) In lieu of the use of treated wastewater from an on-sIte sewage treatment facility, and approve various in- lieu payments to the City'S Wastewater and Stormwater Management funds. BACKGROUND At their meeting of March 8, 1988 Council approved a Sewage and Water Conservation Compliance Agreement (Agreement) for the Water Garden development. Among other requirements, the Agreement required that all wastewater generated by the project (with the exception of restaurants) be treated In an on-site treatment system and used for landscape irrigation, replenishment of the artificial lake and other water features and for tOilet and urinal flushing In Phase II of the proJect. 1 roD JUN 29 1999 An on-site wastewater treatment and reclamation plant was constructed as a part of the Phase I Water Garden project and has been operating for approximately eight (8) years. The treatment capacity of the on-site system IS approxImately 25,000 gallons per day which has proved to be insufficient to supply all of the landscape imgation and lake/fountain replenishment needs of the project. The responsibility for operation and maintenance of the plant rests with the Phase I owner (Tooley & Company) With the City performing an oversight role in conjunction with the Regional Water Quality Control Board which issues the operating permits for the plant The Water Garden Phase II development is now in the early construction phase and, under the terms of the Agreement, must also provide for on-site treatment of sewage to produce reclaimed water for use In additional landscaping, water features and tOilet and unnal flushing within Phase II bUildings Per the terms of the original Development Agreement, the Phase I AND Phase II projects have been granted a 90% credit on the Sewer Connection Fee In consideration of the sewage flow reductions achieved by the on-site treatment plants DISCUSSION Over the past several months the developer of Water Garden Phase II. J.H Snyder Company, and City staff have been discuSSing vanous aspects related to the design of the off-Site and on-site improvements reqUIred as a part of the final Water Garden development phase During these diSCUSSions, It became apparent to both the City and 2 the J H. Snyder Company that a better approach to reducing the demand for potable water In the project would be a tie-In WIth the planned DWRRF project located by the Santa Momca Pier. As more specific discussions on the feasibility of a DWRRF connection ensued, the City was approached by Tooley & Company, owners of the Water Garden Phase I, who were also Interested In discussing alternatives to continued operation of their on-site sewage treatment facility due to technical, safety and cost issues associated With the plant. The Phase I owners also perceived a tie-in with the City's DWRRF project as a less problematic and more cost-effective approach The benefits to the Water Garden Phase I and Phase II owners from a tie-in to the DWRRF m lieu of on-site sewage treatment are three-fold: 1} use of reclaimed stormwater will cost less over time than use of reclamled wastewater primarily due to the elimination of expensive operation, maintenance, repair and compltance testing costs associated With the on-SIte sewage treatment systems; 2) the on-site sewage treatment system has proved to be less reliable than anticipated and cannot be cost- effectively upgraded to meet increased exterior water demand; and 3) the de- commissioning of the on-site plant Will alleViate many employee and viSitor health and safety concerns which are outside of the core competency of the project owners The benefits to the City from a tie-in to the Water Garden project are also three-fold: 1) less potable water will be used at the site than would be the case With on-site treatment systems since the DWRRF project will be capable of supplying additional reclaimed water to meet fluctuating demand and Will have much greater reliability; 2) the tie-In to 3 the Phase" tOilets and Urinals will provide an average dally demand for reclaimed water which is more constant arid stable than landscape irngation demand and will therefore Improve the profile of the DWRRF's customer base; and 3} the proposed Agreement modIfications Will result In additional revenues to the Sewer Fund which will be used for citywide sewer upgrade projects, and additIOnal revenues to the Stormwater Management Fund which WIll be used to pay for the Clty's costs of extending the reclaimed water distribution line to the Water Garden site. offset the City.s on-going DWRRF costs as well as finance additional stormwater mitigation projects In the community. Under the terms which staff has negotiated With Water Garden Phase I, a total payment of $1 million would be made to the City in lieu of continued operation of the on-site treatment facility. Of this amount, $694,172 represents the remaining 90% balance of the sewer connection fee which was Originally aVOIded by the project and would be depoSIted In the Sewer Fund. The remaining $305,828 would be deposited In the Stormwater Management Fund. These amounts would be paid In three equal installments as follows: one-third to be paid prior to January 1, 2000; one-third to be paid prior to January 1, 2001, and one-third to be paid prior to January 1, 2002. Under the terms which staff has negotiated With Water Garden Phase II, a total payment of $1,788,000 would be made to the City In lieu ofthe construction and operation of an on-sIte sewage treatment faCility Of this amount, $558,000 represents the remaining 90% of the full sewer connection fee which was Originally avoided at the 4 time of building permit Issuance and would be deposited In the Sewer Fund. This amount would be paid In full within 45 days of the execution of the modified Agreement. The remaining $1,230,000 would be depoSited in the Stormwater Management Fund and would be paid In three equal installments as follows: $410,000 to be paid prior to Issuance of a certificate of occupancy for the proJect, $410,000 to be paid WIthin one year of the Issuance of a certificate of occupancy; and $410,000 to be paid within two years of the Issuance of a certificate of occupancy for the project For both Phase I and Phase II, the City would also agree that at no time would the price of DWRRF reclaimed water supplied to the Water Garden by the City exceed the prevailing potable water rates charged to the City's water customers. BUDGET/FISCAL IMPACT There are no expenditure impacts assOCiated With approval of the proposed modifications to the Agreement except for the additional cost of extending the proposed DWRRF reclaimed water line from OlympiC Blvd. and 17*' street, as is currently planned, to OlympiC Blvd and 26th Street. Since the deSign and bidding process for the DWRRF distribution system will not be completed until the fall of this year. a preliminary estimate IS that thiS additional cost should not exceed $200,000 which will be more than covered by the Increased revenues to the Stormwater Fund which would result from execution of the modified Agreement If approved by Council, the modified Agreement would result in additional unrestricted 5 Sewer Fund revenues In the amount of $1,252,172 to be deposited In Sewer Fund account #31-500-661-00000-0263-10000. and additional unrestricted Stormwater Management Fund revenues in the amount of $1,535,828 to be deposited in Stormwater Fund account #34-500-661-00000-0295-10000. RECOMMENDATION It is recommended that Council Authorize the City Manager to negotiate and execute a modification to the Sewage and Water Conservation Compliance Agreement with Water Garden Phase I and Phase II to require the use of reclaimed stormwater in lieu of reclaimed wastewater for non-potable exterior and interior water uses.
