|Number of Ballots||205||44|
Jim Petropulos, Director of Mariposa County Public Works Department is mailing a newsletter to all Yosemite West property and home owners the week of March 29, 2004. This newsletter will further detail project funding and financing. The project will be open to bids starting April 23, 2004. Please contact Jim Petropulos at any time with your questions or concerns.
The Clerk of the Board of Supervisors for Mariposa County mailed the Notice of Proposed New Assessments and Assessment Ballot for the Yosemite West Wastewater Facilities Project to property owners the second week of March 2004.
Enclosed with the assessment ballot is a Summary of the Method of the Levy of the Assessments. This document is available to download: page 1, and page 2.

Important dates to note are:
The Yosemite West sewer system suffered a major failure in May 1998 with effluent surfacing from the over-saturated leach field and flowing downslope towards, but not reaching Indian Creek, a tributary of the Merced River. The California Regional Water Quality Control Board (RWQCB) and the Mariposa County Health Department were immediately notified, as required by law. The Mariposa County Board of Supervisors passed an emergency ordinance barring any further sewer hook-ups in Yosemite West pending resolution of the sewer problem. The RWQCB subsequently issued a Cease and Desist Order prohibiting any further surface releases of effluent from the leach field, and requiring preparation and implementation of a repair program to ensure future compliance.
Emergency temporary improvements were implemented, including construction of a large new aeration pond, in order to bring the system into compliance. Approximately $1 million was spent to make these improvements, financed by a loan from Mariposa County to the Yosemite West Maintenance District.
In June 2001, the Mariposa County Board of Supervisors selected the engineering solution for the more permanent re-building of the Yosemite West sewer treatment and effluent disposal system, and also authorized the Mariposa County Public Works Department to proceed with detailed engineering specifications.
The current proposal will make use of the existing sewer site plus the adjacent parcel to which the Yosemite West Maintenance District has access. No new land needs to be acquired. The existing treatment facilities would be re-conditioned and improved. Effluent would be disposed of via a new system of underground drip emitters. The emitters would be buried about one-foot deep (which is below the winter frost line) and the effluent dispersed by the emitters should not reach the surface. The existing leach field would be mothballed, and only used for emergency back-up.
To finance the project, a loan will (hopefully) be received from the federal government. To repay the loan, each Yosemite West parcel will be assessed a sum yet to be determined. California law (Proposition 218) requires that a vote be taken in order to approve or disapprove these assessments for the sewer improvements. The so-called "Prop. 218" votes will be weighted by the assessments (i.e., lots with larger assessments will have a proportionately greater vote), and a majority of the returned ballots will decided whether the project (including loan and assessment) will go forward.
The cost allocation methodology involves assigning "equivalent development units" or "EDUs" to each lot, whether improved or unimproved, vacant or occupied. The total project cost will be divided by the total number of EDUs, and then costs assigned to individual lots. The process is fairly complicated, but in a nutshell:
Using these figures, there will be a total of about 350 EDUs:
Some additional capacity (approximately 10,000 gallons/day) will be separately funded by Mariposa County. This "reserve" will be available for future use.
YWPHI has decided not to take any formal position on the upcoming Proposition 218 vote. It will not recommend that Yosemite West residents, home and lot owners, vote for or against Mariposa County's proposal. Rather, YWPHI will leave that determination to individuals. However, the following information is being provided to better inform the community:
The initial environmental study for the Yosemite West wastewater treatment upgrade project has been completed. Public agencies had until September 3, 2002 to provide written comments and objections on the study.
