Horstkotte, Jr., General Manager -Chief Engineer SUBJECT: ADJUSTMENTS OF SECONDARY WATERSHED TRUNK SEWER CHARGES AND INCLUSION IN DISTRICT CODE Immediately following the review of the watersheds south of the City of Walnut Creek (LID 30), we studied the balance of the watershed plans adopted by the Board of Directors. Increasing sewer construction costs, changes in land uses, an earlier return of funds invested by the District (with an increase in District reserve funds) motivated this review. We have been making an annual review of the status of each watershed and have recommended previous increases, but spiralling construction costs of the past two years indicate the need for new adjustments. Many of the watersheds were estimated some time ago and are affected by longer term increases. For example, the ENR index for 1966 construction was 1200 for the San Francisco area and that index is now at 2236 (November 1973). Our plans had a built-in average increase of 6% and last year the actual increase was 11.5%. Attached is a chart summarizing our review and recommended increases. The effective date could be as early as March 1, 1974, or as late as July 1, 1974. It is also recommended that secondary watershed plans and charges be included in the District Code. In this manner they will have more official and legal status. They have been related to and considered part of the Rebate Facilities section and we would propose to incorporate them therein, as follows: CHAPTER 9. REBATE FACILITIES. Sec. 9-101. Definitions. Add - (10) Watershed trunk plan means the engineering and financing plan adopted by the Board upon the Engineer's recommendation for each secondary watershed area of the District setting forth therein the proposed facilities and unit charges established therefor. Renumber Article 6 to Article 7 and insert the following: ARTICLE 6. SECONDARY WATERSHED TRUNK SEWERS Sec. 9-601. Adopted Watershed plans and payment of charges. Sec. 9-602. List of adopted secondary watershed trunk sewer plans. Sec. 9-601. Adopted watershed plans and payment of charges. The Board of Directors has adopted the secondary watershed trunk sewer plans a::id charges listed in Sec. 9-602 and no person may connect to the District sewer system within any secondary watershed service area listed unless he pays the watershed trunk sewer charge.

New Bus. 10 1/3/74 December 28, 1973 MEMORANDUM FOR: HONORABLE MEMBERS OF THE BOARD OF DIRECTORS FROM: G. A. Horstkotte, Jr., General Manager -Chief Engineer SUBJECT: AUTHORIZE $8,500.00 FOR INFILTRATION/INFLOW STUDY - LAMPMAN & ASSOCIATES PROBLEM: In order to get further grant approval for the Treatment Plant, E.P.A. will require generalized field monitoring of dry and wet weather flows of all subbasins of District and analysis of their results. Due to our workload we do not have the technical personnel available at this time to conduct a study of this magnitude within the time frame. BACKGROUND: Lampman & Associates are consultant engineers for only governmental agencies. They do have background and experience in setting up this type of study. As indicated by their letter, this would be a joint effort between their firm and the District. They would establish the infiltration -inflow monitoring system, select the monitoring stations, review data. collection. procedure, develop preliminary analysis of data and all other necessary office work. The District personnel would perform all of the field duties such as establishing the monitoring station, collecting flow data, etc. It is my suggestion that we authorize Lampman and Associates to proceed only with Phase I at a cost not to exceed $8,500.00 as indicated in their proposal. We have been advised by E.P.A. and the State that 87.5% of the total cost of this study by Lampman and Associates and District personnel is eligible for recovery under the grant.

New Bus 11 1/3/ 74 December 27, 1973 MEMORANDUM FOR: HONORABLE MEMBERS OF THE BOARD OF DIRECTORS VIA: G. A. Horstkotte, Jr. - General Manager -Chief Engineer SUBJECT: AUTHORIZATION TO APPOINT ED ABEL SENIOR CONSTRUCTION INSPECTOR PROBLEM: Workload in the Inspection Division requires more coordination. We are now heading into the 1974 construction season and I would like to make this appointment now, prior to the beginning of that construction period. BACKGROUND: The Inspection Division was reorganized under the Engineering Department on July 1, 1971. At that time Mr. Abel's (Civil Engineering Assistant I Range 56 $1083-$1317) duties were expanded to handle the office work for the Inspection Division. Much of his activity involves checking Job Engineer's plans to see they are in conformance with the District's code and specifications. He is in close contact with the Engineers, Developers, Contractors and Inspectors involved in these projects. In the past two years his workload and duties have expanded to the point where his entire time is devoted to Inspection related work. Also, at times his workload is such that we temporarily assign a Construction Inspector Assistant to assist him in this work. It is requested that Mr. Abel be reassigned to the Inspection Division where he will be working directly under Mr. Ramsay, Supervisor of Inspection, to assist in the overall coordination of inspection operations. His position as Senior Construction Inspector (Office) will permit him to work closely with the other members of Inspection Department (now eleven) and more effectively coordinate the functions of the Division. This adjustment would result in a salary change from Range 56E $1317 to Range 59D $1349 which is within my authorized 1973-1974 budget. RECOMMENDATION: We request the following Resolution be adopted: Resolution No. A Resolution transferring Ed Abel's appointment as Civil Engineering Assistant I (Range 56 $1083-$1317) to Senior Construction Inspector (Office) - (Range 59 $1165-$1417).

BACKGROUND: This State and Sacramento County Utility District in parti- cular, have been in the fore front of chemical root treatment. This District has worked extensively with chemicals over the last 3 years. We have been particularly concerned with application. We know roots can be controlled by chemicals using the soak method, but our District does not lend itself readily to soaking so we have worked on spray applications a great deal. I feel it would be very beneficial to participate in this program. APWA anticipates an expense of $3,000 to $10,000 per partici- pant. I would anticipate expending around $5,000 in this work anyway. It may be possible to have some of the costs reimbursed through a grant. RECOMMENDATION: That we advise the APWA Research Foundation of our will- ingness to participate in Project 73-8.

BACKGROUND: On Monday, November 26, 1973, the District received a call to relieve an overflow at the address mentioned above. Upon arrival, the crew found the 6" line H-10 plugged 170' upstream from MH-100 toward MH-101 on San Luis Road. The stoppage consisted of loose roots and was cleared with no difficulty. The District crew cleaned and disinfected throughout and an overflow device will be installed. 3. RECOMMENDATION: The total claim comes to $125.01 and it seems to be reasonable for this type of damage. I recommend this claim be paid. Respectfully submitted, Robert H.

New Bus. 2 1/3/ 74 December 18, 1973 MEMORANDUM TO: THE HONORABLE MEMBERS OF THE BOARD OF DIRECTORS VIA: G. A. Horstkotte, Jr., General Manager -Chief Engineer SUBJECT: ADJUSTMENT OF UNIFORM REBATE FEES The establishment of uniform rebate fees has been based historically on the cost of area installations which are, in general, determined by terrain, soils, street improvements, density of land use, time of construction, and competition among contractors. A major determinant for many years, where comparable, has been the cost of local sewering under the District LID program, since it has been considered a fair measure of unit costs of sewers applicable to rebate areas. Construction costs based on the ENR index have doubled since 1965 and our last adjustment of uniform rebate fees was in 1967. In reviewing the present code provisions which classify according to terrain and density, it would seem most appropriate not to change the classifi- cations but to insert ranges of fees reflecting increases in costs since 1967 and a reasonable allowance for the future. Retaining the present classifications would result in a minimum of changes in present rebate jobs, and by expanding the fee schedules within each classifi- cation the recognition of cost appreciation can be accomplished. The changes would apply primarily to new installations, and the review of existing classifications would be minimized. The updating of related cost areas would be confined to comparisons with LID proceedings. Suggested changes: (1) Class I $650 Change to (a) $650, (b) $1,000, (c) $1,400 (2) Class II $1,000 Change to (a) $1,000, (b) $1,400, (c) $1,700 (3) Class III $1,400 Change to (a) $1,400, (b) $1,700, (c) $2,000 (4) Class IV $1,700 Change to (a) $1,700, (b) $2,000, (c) $3,000 (5) Class V Change to (a) $2,000, (b) $3,000, (c)-$4:,000 (6) Class VI $12.00 per front foot or $0.06 per square foot of served property Change to $15,00 per front foot or $0.10 per square foot of served property Charges included in the above for District administration would remain unchanged. The adoption of revised class -if icat:ionsis not critical and an effective date of July 1, 1974 is recommended. Respectfully submitted, UIJVC���� W. C.

Horstkotte, Jr., - General Manager -Chief Engineer SUBJECT: AUTHORIZE $3,000 TO PREPARE E.I.R. FOR PSA 51, SPRINGHILL LANE, LAFAYETTE AND RELEVANT PRELIMINARY INFORMATION PROBLEM: The property owners within PSA 51 are requesting the Sanitary District to proceed with the formation of a Local Improvement District to sewer their area. In order to recover the District Expenses through the Local Improvement District proceedings, it is necessary that we have Board approval and set up a drawing account for PSA 51. BACKGROUND: Five residents living within the tentative boundaries of PSA 51 attended the December 6, 1973 Board Meeting, requesting Board take affirma- tive action on PSA 51. Staff was instructed to review PSA 51 and report back to the Board. The Engineering Staff had requested the property owners within the PSA have their petitions and letters in order by December 6, 1973 so an evaluation could be made by the District Staff and Attorney as indicated below. Referring to the sketch on PSA 51, posted on the bulletin board within the Board Room, the tentative boundary of PSA 51 is outlined in yellow. Within the PSA there are 11 properties, all developed. They have signatures repre- senting 72.7 of area and 87% of the assessed valuation, and five supplemental letters requesting sewers be installed from petitioners. The three properties on Springhill Court, colored in red, have presented letters requesting they not be included within PSA 51 and since they are outside of the Sanitary Dis- trict we do not intend to include them. Our staff has advised all of the property owners contacted that the estimated cost of a Local Improvement District for this area would be approximately $5,000 per building site. The staff_ advised the five residents who attended the December 6, 1973 Board Meeting that this item was going to appear on the January 3, 1973 agenda and it would not be necessary for them to attend. We have a letter from the Health Department of Contra Costa County dated November 26, 1973, attached, urging the District to proceed with the forma- tion of a Local Improvement District. In view of the foregoing the Staff is recommending the following procedures be followed in formation of future PSA's: [11 District costs for informing property owners in seeking sewering is charged to a "general account" until the Board officially establishes the PSA on basis of legal signature requirements for L.I.D. formation. [21 Request Board approval to proceed with the PSA and establish a drawing account.
