DATE: September 2, 1980 DEPARTMENT: Engineering SUBJECT: LAKE CALAVERA HILLS EFFLUENT DISPOSAL LINE - ALIGNMENT STATEMENT OF THE MATTER The Lake Calavera Hills developer has proposed an alignment for the effluent disposal line which will ultimately connect the Lake Calavera Hills Reclamation Facility to the Encina Ocean Outfall.. Before proceeding with design, the developer is request- ing City approval of the alignment. The proposed alignment has the advantage of capability for dual use in a reclaimed water distribution system and ease of acquisition. In a joint meeting with the probable design engineers for the proposed Palomar Reclamation Facility, Rick Engineering and City staff, there was general agreement that the proposed alignment would accommodate effluent disposal as well as reclaimed water distribution. FISCAL IMPACT The operation of the line for effluent disposal will require at least two pump stations. The cost of operation and maintenance of these stations will depend on pipe size, line elevation, projected water volumes and other yet-to-be deter- mined design considerations. EXHIBITS Map of Proposed Alignment Staff Report RECOMMENDATION That the City Council approve the approximate alignment of the Lake Calavera Hills excess effluent disposal line as shown on Exhibit "A". Council Action: 9-2-80 Council approved the approximate alignment of the Lake Calavera Hills excess effluent disposal line as shown on Exhibit "A". DISPOSAL LINE MEMORANDUM TO: City Manager FROM: City Engineer DATE: August 21, 1980 SUBJECT: LAKE CALAVERA HILLS EFFLUENT DISPOSAL LINE - ALIGNMENT The Lake Calavera Hills developer has proposed an alignment for the effluent disposal line which will ultimately connect the Lake Calavera Hills Reclam- ation Facility to the Encina Ocean Outfall. In order to proceed with right- of-way acquisition and design of the pipeline, the developer is requesting City approval of the alignment. The proposed alignment begins at the reclamation facility and proceeds south- west along Tamarack Avenue to El Camino Real. It then follows El Camino Real alignment to the bridge near Rancho Carlsbad. From Rancho Carlsbad the align- ment proceeds south to intercept the San Marcos County Water District Effleuent Disposal Line in Palomar Airport Road. The alignment proposed by Lake Calavera Hills is generally within existing utility or access easements. Between El Camino Real and the Koll Business Park the alignment is in an unimproved access road serving several otherwise landlocked lots. After leaving the Koll property (where the proposed align- ment is within proposed street rights-of-way), the alignment is for the most part coincident with either Costa Real Municipal Water District or San Diego Gas & Electric easements. According to the developer, the property owners are aware of the proposed location of the easement and have voiced no objec- tions. On August 1, 1980, the City mailed notices to all affected property owners (see attached letter) and has at this date received acknowledgement only from the YMCA. From an engineering standpoint the proposed alignment for the effluent dis- posal line is one of several possible alternatives. Its advantages include the capability for dual use in a reclaimed water distribution system and its potential for ease of acquisition. The evaluation of the alignment from a hydraulic standpoint (cost of operation) is not clear since no design work has actually been accomplished. There is general agreement between the City Engineering staff, Lowry and Associates and Rick Engineering that the pro- posed alignment would present no unusual engineering problems and it would be a feasible alignment. If condemnation action is necessary, some additional design work will have to be accomplished before the Council could make a finding that the proposed alignment is "most compatible with the greatest public good and the least private buying."

The City of Carlsbad is proposing construction of a reclaimed water pipeline between El Camino Real, south of Rancho Carlsbad and Palomar Airport Road near Laurel Tree Lane, The proposed pipeline alignment may affect your property and the City wants to insure that you have some imput into the planning process.. We are enclosing a copy of the assessor's maps on which we have sketched the proposed alignment. We have on file in our office topographic maps and aerial photos which better define the precise alignment of the pipeline. We wou"! d appreciate your comments on the proposed pipeline alignment as soon as possible. The City Council will "probably be considering adoption of an alignment in late August or early September.

Final Subdivision Map for Tract 76-12 By Resolution No. 5145, the City Council of the City of Carlsbad approved a tentative subdivision map, Tract 76-12, for a 142-lot subdivision and by Resolution No. 5146 also approved a planned unit development permit (PUD-4) for said subdivision. Tract 76-12 is a portion of the Calavera Hills Master Plan (MP-150a) approved by the City Council as Ordinance No. 9517. Tract 76-12 is anticipated to be the first portion of the Calavera Hills Master Planned Area to be developed. As you know, in connection with satisfying the need for sewer service for the Master Planned Area, Lake Calavera Hills Associates has obtained approval in Resolution No. 5871 of the City Council of the City of Carlsbad for a precise development Luce, FORWAR'D, HAMILTON & Mr. Frank Aleshire July 8, 1980 Page 2 plan (PDP-2) for a 1.2 million gallons per day waste water treatment facility and that Lake Calavera Hills Associates and the City of Carlsbad have entered an agreement for construction of the satellite plan. Construction of the sewage treatment and waste water reclamation facility is presently underway with substantial progress being made toward anticipated completion of the sewer plant itself this fall. Lake Calavera Hills Associates desires to obtain its final subdivision map approval for Tract 76-12 at this time. One of the conditions to final subdivision map approval is that the City Council find as of the time of such approval that sewer service is available to serve the subdivision. While the Lake Calavera Hills satellite sewage treatment plant is not yet in operation, the substantial progress that has been made to date combined with the present availability of sewer capacity to the City of Carlsbad through the Encina plant allows the condition of final subdivision map approval for Tract 76-12 to be satisfied by assigning 142 EDU's from Encina plant capacity to Tract 76-12. Final subdivision approval for Tract 76-12 is necessary at this time in order to initiate at the earliest possible date the long process of constructing the homes that will provide the raw sewage for operation of the satellite sewage treatment facility. In making the request for allocation of Encina plant capacity, it is intended and expected that the allocation be temporary in nature until the satellite sewer treatment facility is operating at which time sewer capacity to be used by Tract 76-12 will be provided by the Lake Calavera Hills satellite sewage treatment plant. Lake Calavera Hills Associates wishes to emphasize that its request is not for a permanent allocation of 142 EDO's from the Encina plant capacity, but an allocation presently made so as to allow final subdivision map approval with ultimate sewer service anticipated to be from the Lake Calavera Hills satellite treatment facility. Adoption of Final Alignment for Sewer Outfall Line An integral part of the construction of the Lake Calavera Hills satellite sewage treatment plant and reclamation facility is the construction of a sewer outfall line connecting the satellite plant to the Encina plant's ocean outfall disposal line. Final planning, design and ultimate construction of that outfall line is presently awaiting the City of Carlsbad's action and commitment to a specific alignment. It is our understanding that the final alignment of the outfall line 7 oLUCE/FORWARD, HAMILTON & SCRIPPS Mr. Frank Aleshire July 8, 1980 Page 3 has been before the City Council as part of the City Council's consideration of the overall waste water reclamation facilities master plan for the City of Carlsbad, but that final City Council determination and commitment to an exact alignment has not been made at this time. It is important that final action establishing the alignment be taken so that the planning, design and construction can move forward. As one can easily imagine, the problems of coordination among the various agencies and property owners who must participate in the design and construction of the outfall line as well as the lead time necessary to secure any and all rights of way is considerable. However, none of these activities can be completed absent the City's commitment to a final alignment. The City's timely consideration of final alignment not only affects the ability of Lake Calavera Hills Associates to timely complete its satellite sewage treatment plant and waste water reclamation facility in accordance with the agreements with the City, but also affects the Palomar Airport satellite plant being proposed by Roll Company and others. Should you or any of the staff have any questions regarding our requests or need any further information, please do not hesitate to call me or Lake Calavera Hills Associates. We hope these matters will be taken up immediately by the City of Carlsbad and any City Council hearings scheduled at the earliest possible date. Thank you for your assistance in these matters.
