Council Action: 9-19-78 Council directed staff to reserve not less than 75 EDU's for City Capital Improvement Projects and failing septic systems out of the 102.5 EDU's currently unallocated. MEMORANDUM TO : City Manager FROM : City Engineer DATE : September 8, 1978 I Date 11/22/77 I2/20/77 04/ I I /78 04/ 16/78 - SUBJECT: REMAINING SEWER CAPACITY - NUMBER OF EDUS AVAILABLE Pursuant to your request, I have reviewed Council actions since the adoption of the sewer moratorium and prepared a listing of available sewer capacity and past Council allocations. These are presented in the attached "Sewer Allocation Summary." The compilation of this list and its significance are d i scussed be I ow. Original Encina Capacity In a mem to the City Manager, dated October 27, 1977, the Public Works Ad- ministrator reported to Counci I that 106 EDUs of the City's original Encina capacity still remained uncommitted. This remaining capacity was to be held for miscellaneous exceptions to the sewer moratorium. Itemized on the attached "Sewer AI location Summary" are exemptions to the mratorium which were credited to this reserve. The current balance of the remaining origi- nal Encina capacity is 45 EDUs. Fi rst Phase Sewer AI location Svstem In addition to the original Encina capacity, Carlsbad acquired 270 EDUs of additional sewer capacity through a lease arrangement with the Encinitas Sanitary District. This capacity was subsequently distributed through the Fi rst Phase Sewer A I I ocat ion System as noted be I ow: SEWER ALLOCATION SYSTEM - 270 EDUs Single Multiple Community A.B.

This actually leaves 36 EDUs in the single-family category which, togeth- er with the 25 EDUs in the commercial category, were redistributed to the community facilities and contingency categories. Although only 61 EDUs (36 + 25) were available, 62 EDUs were redistributed by Resolution No. 5371 - 40 EDUs to community facilities and 22 EDUs to contingencies. To accommodate the arithmetic error of one EDU, I have assigned-39 the community faci I ities category rather than 40 EDUs.

If, however, only this year's Capital Improvement Program is considered, a total of 40 EDUs will be required (instead of 151 EDUs) leaving a total of 62.5 EDUs available. Still another potential source of sewer service demands is failed septic tank systems. Assuming six to eight septic system failures per year, approximately 30 to 40 EDUs wi I I be required over the expected f ive-year moratorium period. If a commercial septic tank failure occurs, such as the Country Store on El Camino Real, the sewer service demand could be considered greater than the estimated 30 to 40 EDUs. Summary In summary, it appears as if, over the expected moratorium period of five years, the combination of City Capital Improvement Projects and failed septic systems will require approximately twice as much sewer capacity as is currently available in all the remaining allocation categories. It is suggested that Counci I determine whether or not to reserve sewer capacity for the ent i re proposed f i ve-year Capita I Improvement Program. This policy determination should be made prior to any further allocations from the cont i ngency reserve. Recommen dation Based on the potential of additional EDUs being made available in the next five years (treatment plant rerating, inland treatment plants, water conservation, etc.), I would recommend that out of the 102.5 EDUs remaining, no less than 75 EDUs be reserved for upcoming City Capital Improvement Projects - and failing septic systems. all other categories to be allocated at City Council's discretion. This would leave only 27.5 EDUs for 9m-@+ Tim Flanagan City Engineer (/ TCF: FNL: veb CC: Pub1 ic Works Administrator P I ann i ng Di rector Redeve I opment Coord i nator SEWER ALLOCATION SUMMARY Balance of original Encina capacity - 106 EDUs Date A.B.

This left 27.5 EDUs remaining available for allocation as the Council determines is in the best interest of the community. It is important to note that there are no "categories" to determine which uses are appropriate since the previous "categories" of the al location system have been combined into the one reserve. Also at the September 19, 1978 Council meeting, two additional allocations were approved by Counci I (Lincoln-Mercury, 6.6 EDUs and Chrysler Plymouth, 14.6 EDUs). Also, since the preparation of the engineering report, we have had two failed septic systems. As of this date, there now remains: (a) 73 EDUs reserved for City Capital Improvement Projects - and failed septic sys- terns and (b) 6.3 EDUs reserved for "other". Whi le there are only 6.3 EDUs remaining in the discretionary "category", there has been a high interest from potential developers regarding sewer availability. Most of the recent inquiries have been informal and the projects need much more than is currently available. However, three re- quests have been formal ized. The three requests are as fol lows: App I i cant Reauest Received Jeff Blankenship April, 1978 H. Von Packard September 14, 1978 Cal ifornia Aqua- September 22, 1978 cu I ture, I nc.
