SEWER DESIGN FLQV7S CRITERIA USED: Overall density was based on the terrain of the basin and the yield of the tv,'0 subdivisions submitted and approved. Overall Density = 4 D.U./Acre 3.5 persons/D-U. 100 gallons/person/day The resulting average flows were then multiplied by a peaking factor as shown on the attached chart (derived from the "North Coastal San Diego County Sewerage Survey" - Rawn Report) The results and the resulting design pipe sizes are tabulated on the attached "Exhibit "A". Calculations for the pipe sizes selected are enclosed in the form of copies of the corrtputor tapes. V.C.P. was selected and an "N" Value of 0.013 used. A minimum velocity of 2.0 ft/sec. was maintained in all but the last run of pipe at design flow. (Upstream 15" V.C.P. - V = 1.9 ft./sec.) Manhole spacing v;as held to a maximum of 350 ft. in almost all cases. \ V Jo 1 N3 N3 V f I 5 *1 <5 1 6/72 0-2 ASSOCIATED ENGINEERS Inter-Office Correspondence SUBJECT: TO • FROM MESSAGE 6/72 0-2 SUBJECT: ASSOCIATED ENGINEERS Inter-Office Correspondence D£s/<3iy CAI~CS. - /X'AK'C^O A>V COSTA SE DATE • TO • FROM MESSAGE 4 ^ M^p»»:w- RANCHO LA COSTA SEWER PUMP STATION PEAK FLOWS Q 3,217 G.P.M. (See Exhibit "A") S±'i', The site selected for the pump station was chosen based on several factors: (1) The land is owned by Rancho La Costa. (2) The ele'vation is at 10-feet above mean sea level. This allows 4-feet of freeboard above the '"Intermediate Regional Flood" (100 year flood) and 1.5 feet above the "Overflow limit line of the Standard Project Flood" as delineated in a report to San Diego County by the U.S. Corps of Engineers, dated April, 1971. (See attached) (3) Geologically the site is on the upper (easterly) slope of the alluvial deposit and should be well clear of any mud or silt deposits. Ground water is expected however. A Smith & Loveless "Capsular" pumping station was selected for both its pre-tested reliability and ready availability as V7ell as aesthetic considerations. Additional gunite protection may be desireable based on chemical analysis of the ground water, A 4,0C0 gallon wet well of conventional reinforced concrete construction is provided. The only above ground items will be the access hatch to the station and a protection structure for the standby power generator, regular pov/er is to be supplied by underground conduit from the south end of Lagoon Lane. The entire perimeter of the station site is to be suitably landscaped and fenced. Q max. ^ 3,217 g.p.m. Tobal Lift = 131 " (-6) - 137 ft.

Dear Mr. Finney Enclosed herewith is an original and one copy of a "Application for Service" for the fresh water service to the Lagoon Lane sewage pumping station. The District is getting ready to make the service connection, so that we ask you to have the appropriate official of the City of Carlsbad execute the application and we ask that you return same to this office for processing. We have noted in the field the changes that you have made in locating the force main in Lagoon Lane in the vicinity of our 8-inch water main. We ask that you furnish to this office the specific details and "as- built" features of this crossing, in view of the very critical nature of providing adequate separation between our fresh water line and the sewage force main. Of course, we would want the as-built drawings of your sewer project in all of the areas where you are in the proximity of our public water system facilities. Very truly yours Jack Y.

(1) Coordination with the various utility companies was the first item of discussion. Telephone service will be provided from the joint pole line and underground in the same trench as S.D.G, & E. along Lagoon Lane. Kathy Clark of P.T. & T. is to be notified by the Contractor at the appropriate time. (2) The Contractor is to complete the application at A.T. & S.F. Railroad Company to obtain necessary permits for construction on their right-of-way. (3)J The Carlsbad Municipal Water District expressed their desire place the pressure regulator and meter at a location and elevation so as it will be clear of any future curb .construction. This will be almost impossible at this time due to topographic and right-of-v/ay problems. They will however, check further to see if a better location can be found. They also stated that the indicated 3" A.C. line is of no concern to them since it is "downstream" of the meter. The Contractor will check with the City to attempt to substitute 2" PVC at a savings to the Owner, X ^1 September/76 PRE-CONSTRUCTION CONFERENCE Prepared 21 Sept/76 (4) The Contractor is to proceed with obtaining his permit from the State for the freeway crossing and to obtain permission to use a smaller casing size. (5) Quantity measurement of crushed rock bedding was discussed. It was concluded that the best miethcd would be to use actual truck load counts and to decrease this by the calculated amount used to support the pipe in its proper alignment. (6) A preliminary sequence of construction and schedule of fund distribution was presented by the Contractor and discussed briefly. These will have to be studied and modified if necessary (7) Meeting was concluded and adjourned at 12:00 noon. A field inspection was made of the manholes already staked. The alignment as shown appears good. The project is to officially start on Tuesday, September 21, 1976.

Along Avenida Encinas, the District has existing water services (6" & 8") which may be in alignment of sewer trench zone. Contractor was made aware of condition and will take care in not damaging water services. 2. Discussed crossings of existing water mains and contractor will pothole for exact field locations. 3. From Manhole #19, located on easterly right-of-way of 1-5 highway to inspection manhole in Lagoon Lane, the contractor will pothole existing water main to insure exact horizontal and vertical alignment. This portion because of terrain could be constructi on problem and contractor was made aware of same. 4. At 2" water service connection the Carlsbad Municipal Water District requested that the location of connection be placed so that future widening of Lagoon Lane would not necessitate relocation either vertically or horizontally of new 2" service. Henley indicated that District would place new service in existing Carlsbad Municipal WaterDistrict easement. Also discussed was offsite 3" A.C. water line to pump station. The City Engineering Department is requiring this 3" line. It was mentioned by Russ Morrison, City Inspector that line was "future water main". We told all at meeting that the District does not consider this a water main for any future considerations, that we only consider it a water service connection for the pump station 5. Carlsbad Municipal Water District will locate existing water mains for potholing. 6. Henley requested copy of letter from State Health Department to Associated Engineers stating its approval of sewer improve- ment plans. Associated engineers will mail Henley a copy. Construction will begin in September, 1976. Estimate that sewer in Lagoon Lane will be constructed starting in November, 1976. Submitted by jrrr^ Whitley ?3 i l£ WOODSIDE/KUBOTA A ASSOCIATES. INC. _.
