Curran, and Lolita Mahoney, who are owners of approximately 120 acres which is located east of Orange contiguous to Chapman Avenue at approximately the intersection of Newport Boulevard. Each of the owners owns an _undivided one-third interest in said property. None of the owners reside within the boundaries of this property, and there are no registered voters residing on said property~ A portion of this 120 acres was originally included within the boundaries of County Sanitation District No. 7 but was excluded against the wisnes of the owners as a result of .action taken by residents of Orange Park Acres. The owners want to annex this land to Sanitation District #7. Pursuant to your procedures adopted on October 9, 1968, I am enclosing herewith a complete legal description and map of that property for which annexation is requested. Sai.d property consists of two assessor's parcels Y Assessor Parcel No. 093-160-37 093-160-39 Assessed Value $77,200.00 $151,000.00 (building thereon valued at $500) On behalf of the owners, I respectfully request that County Sanitation District #7 annex this territory.

Lawson Mead HLM:cp , COUNTY SANITATION DISTRICT NO. 7 OF ORANGE COUNTY Study of Potential Increases in Sewage Flow _ Resulting From -the Possible Rezoning of Certain Areas In and Adiacent to the Northerly Portion of County Sanitation District No. 7 From Low-Density Residential to Medium-Density Residential Land Use OBJECTIVE The obiective is to estimate the possible increase in sewage flow, over and above that estimated in the Master Plan Trunk Sewer Facilities, dated May 1969, from undeveloped areas of low-density residential zoned property (Orange County Zone AR 10000), within or adiacent to the boundaries of the District, in the event of future rezoning to an ultimate land use of medium-density residential (Orange County Zone R4 (8000), PD(4000)), as recently approved by the Orange County Planning Commission for Tentative Tract No. 7389. GENERAL The master plan includes an area outside the District's boundary of approximately 2,806 acres with an ultimate land use classification of low-density residential (hillside) with small areas of low-density residential (lots above 10,000 square feet), low-density residential, medium-density residential and commercial zone as shown on Pl ate 1 of the master pl an. The areas and unit flow coefficients used in the master plan for determining design flows from the 2, 806 acres are: Land Use Classification Low-density residential (hil I side) Low-density residential (lots above 10,000 square feet) Low-density residential Medium-density residential Commercial Total kea Outside District Boundaries kea in Acres 2,288 83 320 124 91 2,806 B 0 y L r: F N G l N c r.-n I N c Average Unit Flow Coefficients .0010 cfs/ac. .0018 cfs/ac. .0024 cfs/ac. .0060 cfs/ac. .0050 cfs/ac. There are 813 acres of undeveloped property within the District, similar in character to the low-density residential portion of the above 2,806 acres, which . . could also be rezoned to medium-density residential. The land use classifications within the 813 acres and their corresponding average unit flow coefficients as contained in the-master plan are: Land Use Classification Low-density residential (hillside) Low-density residential Area in Acres 622 191 Total Area Within District Boundaries 813 Average Unit Flow Coefficients .0010 cfs/ac. • 0024 cfs/ ac. The recent zone change of 37 .2 acres in master plan tributary area T0-7, which is outside the boundaries of the District, from low-density residential to medium- density residential (Orange County Zone R4 (8000), PD (4000)), as approved by the Orange County Planning Commission on June 8, 1971, and confirmed by Board of Supervisors' Resolution No. 71-817, dated July 14, 1971, results in an increase in density from 3.3 dwelling units per net acre, excluding public streets and parks, to 9 .5 dwelling units per acre as approved for Tract No. 7389. Theoretically, the PD (4000) zone could result in a maximum of 10. 9 dwelling units per gross acre if no public streets are included, since the private streets, common areas and recreation areas of the planned development are included in the gross acreage in computing the number of dwelling units permitted. CRITERIA The following criteria were used in deter ining the probable increase in the estimated sewage flow fro~ the study are , both in county areas and within the present city limits of the city of Orange, if a general rezoning of undeveloped low-density residential land to medium-density residential (PD (4000) should take place at some time in the future. -2 - . '-" ~. 1. The areas of low-density reside~tial land which are now developed will probably remain equivalent to Orange County Zone AR 10000 with an average unit flow coefficient of .0010 cfs/ac. for low- density residential {hillside) and .0024 cfs/ac. for low-density residential. 2. Undeveloped land now zoned low-density residential (AR 10000) having natural slopes of 30 percent or I ess could be zoned R4 (8000), PD (4000) and ultimately reach an average unit flow coefficient of • 0060 cfs/ ac. 3. Undeveloped land now zoned low-density residential (AR 10000) having natural slopes of more than 30 percent will not be developed to a density greater than AR (lOPOO) with an average unit flow coefficient of .0010 cfs per acre. PROCEDURE Using aerial photos dated August 1971, and U.S. Geological Survey contour maps, the study area was separated into the three categories described above for that portion outside the District's boundaries and for that portion within the District's boundaries. Due to time limitations, this study was restricted to the northern portion of District No. 7 where the possibility of future rezoning appears to have a substantial effect upon the District's facilities. The increase in sewage flows from those areas where an increase in population density could occur was determined and the effect of the increased sewage flow on the District's existing and proposed master pl an facilities was calculated. Treatment plant requirements were not studied due to time limitations. -3 - F?. () 1' L F. r: N G I r l L c fi I N c. CONCLUSIONS Based on the above criteria it was determined, for the 2,806 acres outside the District's boundary, that 565 .a·cres are presently developed as low-density residential and will remain as such, 1,706 acres are undeveloped and have natural slopes of 30 percent or less and, therefore, are subiect to rezoning, and 535 acres are undeveloped but not subiect to rezoning due to terrain having slopes in excess of 30 percent. Within the District's boundaries 813 acres are subiect to rezoning . because of slopes 30 percent or less. The increase in flows for the study areas are summarized in Exhibits A and B. The increased flows from the area outside the District including a small portion of the increase from within the District, will be collected by the proposed Tustin-Orange trunk sewer. This increase would require that the Tustin-Orange trunk be enlarged by two pipe sizes for its entire length as indicated in Exhibit A. The additional construction cost for the increased capacity is estimated at about $500 ,000. The increased flows from the 813 acres within the District will require the construction of a new 8-inch VCP relief sewer parallel to the Foothill-Newport subtrunk from the beginning of the Foothil I-Newport subtrunk to Santa Clara and Newport Avenue, and a new 8-i nch VCP relief trunk from Santa Clara and Newport Avenue to the proposed Tustin-Orange trunk at Santa Clara and Esplanade. The estimated construction cost for these two relief facilities to the proposed Tustin-Orange trunk sewer is $240,000. The pipe sizes shown in Exhibit A are adequate to carry the additional sewage from the Foothill-Newport Relief Trunk. A small amount of flow will also be added to the Lemon Heights trunk which has the capacity to handle it. r/j ~ iw ddftc-( --,_. I---· 1 o-v .. iudt .;~J :::: ~/9tCO II 'f 0 c1 £cu... Af Kl. "4t ~ U/JM;f t ;_r(JC -4- n (1 y L E F. N G I N r: F n I N G From Exhibit B it is evident that the estimated sewage fl.ow (6. 1 mgd average) resulting from rezoning of low-density residential land to medium-density residential, for 1, 706 acres outside the District, and 813 acres inside the District will overload al I reaches of the Red Hi 11 Interceptor Sewer and the Sunflower Interceptor Sewer. SUMMARY The possible rezoning of 2,519 acres of undeveloped land from low-density to medium-density residential land use could result in an increase of 6.1 mgd (9.4 cfs) in the average sewage flows tabulated in the master plan for areas tributary to the Red Hill trunk sewer. To conform to the design criteria set forth in Section V of the master plan, it will be necessary to increase the pipe size of all reaches of the Tustin-Orange trunk by two pipe increments (6 inches of pipe diameter) at an estimated additional construction cost of $500,000, and to construct an 8-inch VCP relief sewer for the Foothill-Newport subtrunk at an estimated construction cost of $240,000. An increase of 6.1 mgd (9 .4 cfs) in the average sewage flow would surcharge the entire length of the Red Hil I trunk and the Sunflower trunk as these facilities are now constructed or under contract and increasing their design capacity is not feasible. Due to time limitations we have not been able to evaluate the effect of increased tax revenue due to the increased property values resulting from rezoning, or to estimate the time required to recover the capital cost of $740,000.
