My understanding of the request will be to allow for a second guest home to be located on each of the lots within the subdivision . Left Hand Water District has a policy regarding a second dwelling on any residential building lot : 25 . B. 1. C — Accessory Dwelling : In limited cases, and at the sole discretion of the District's Board, tap service may be provided to two separate dwellings on the same parcel of property through the up ra de of the existing single residential 5/8 inch tap to a residential 3/4 inch tap, in order to qualify for this upgrade, there may be no more than one additional dwelling and the secondary dwelling must be under the common ownership of the person holding the primary residential tap; AND the property on which the two dwellings lie cannot be divided nor the de llin gs separately sold. The taps assigned to each of the seven (7) lots within the Longs Peak subdivision are /flinch and would therefore be adequate for serving both the main home and an accessory dwelling. Since you have indicated that the second (guest) homes will be on the same legal parcel as the primary home, cannot be conveyed separately, and does not create a separate legal lot the District will have no objection to revising the PUD to allow for an accessory dwelling. Please let me know if you have any questions. Best Mega rd s mi ._eft H nd Water District Christopher Smith, PE General Manager copy: Mark Bowman Left Hand Water District P. O.

The property is located in Weld County , CO in an area where OWTSs are necessary . Community water serves the residence . SITE CONDITIONS The property is proposing a 3-bedroom residence as indicated . The septic tank will be upsized to 4 bedrooms . The lot is currently vacant. The new treatment area (STA) is to be located to the southwest of the planned residence . The slope on the site is less than 2 % to the west, although is relatively flat. The current vegetation consists of native grasses . The proposed current land use for the STA is a native area with no landscaping next to a fence. There is no planned construction on the STA after installation . SUBSURFACE The subsurface was investigated on April 24th 2017 by digging two soil profile test pit excavations (Test Pits) 8-feet in depth . A visual and tactile analysis of the soils were performed at approximately 3 to 4-feet below grade . The materials encountered in the Test Pit # 1 consisted of a brown sandy root zone to 12-inches, underlain by sandy loam , slightly silty medium dense , with granular structure shape to 8 . 0 feet, the maximum depth explored . Groundwater was not observed . The materials encountered in the Test Pit #2 consisted of a brown sandy root zone to 12-inches , underlain by sandy loam , slightly silty medium dense , with granular structure shape to 8 . 0 feet the maximum depth explored . Groundwater was not observed . A long term acceptance rate ( LTAR ) of 0 .35 gallons per square foot, will be used to design the OWTS, in accordance with Soil Type 3 outlined in Weld County On -Site Wastewater Treatment System Regulations . Lot 1 . Mark Bowman Page 2 DESIGN SPECIFICATIONS The O IVTS design is based on 3-bedooms and 450 gallons per day proposed . Design Calculations 3 Bedroom = 450 gallons/day 450 / LTAR 0 . 35 = 1286 SF Chamber Bed x 1 . 0 = 1286 SF ( pressurized ) Chambers x 0 . 7 = 900 SF Proposed four rows of 19 chambers for a total of 76 chambers and area of = 912 SF The septic tank will be upsized to accommodate additional bedrooms in the future . Install a 1250 gallon 2-compartment concrete septic tank , with risers and lids to grade , followed by a 500 gallon single compartment septic tank with an Orenco P-30 pump package . The tanks may be no deeper than 4 feet. Pump calculations attached . The pump must be capable of 63 . 7 GPM and 24 .4 feet Total Dynamic Head . The tanks should be traffic rated if placed in driveway . Effluent will be dosed through a 2 " discharge pipe , to drain after each dose , and serve a 1 . 5" diam manifold , and 1 . 5" diam laterals . The laterals must have 5132" holes on 3 foot centers facing up with two holes facing down in each lateral for drainage . Each lateral must end in a 90 degree elbow facing up with a ball valve for flushing in a valve box, accessible from grade . An observation port is required . The STA► must have 76 chambers for a total area of 912 SF . The component manufacturers are typical of applications used by contractors and engineers in this area . Alternatives may be considered or recommended by contacting our office . Construction must be to County Land Use Regulations , and On-Site Wastewater Treatment System Regulations , the OVVTS Permit provided by the county, and this design . REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation . A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots) , provides a maximum transpiration rate , and competes well with successional species. No trees or shrubs , or any vegetation requiring regular irritation shall be placed over the STA. Until vegetation is reestablished , erosion and sediment control measures shall be implemented and maintained on site . The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWlS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance . Geo-fabrics or plastics should not be used over the absorption area. No heavy equipment, machinery , or materials should be placed on backflled STAs. Livestock should not graze on the STA . Plumbing fixtures Lot 1 . Mark Bowman Page should be checked to ensure that no additional water is being discharged to OWNS . For example , a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. The homeowner should pump the septic tank every two years , or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized , and non -biodegradable materials should not be placed into the OWTS . Grease should not be placed in household drains . Loading from a water softener should not be discharged into the OVVTS . No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the O NTS . The OVVTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump , air release valves and weep holes must be installed to allow pump lines to drain to minimize risk of freezing . The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high water alarm breaker and from any other control system circuits . The pump system shall have a switch so the pump can be manually operated . If bedrock is encountered our office should be contacted . Excavation equipment must not drive in excavation of the STA due to the potential to compact soil . Extensions should be placed on all septic tank components to allow access to them from existing grade . Backfill over the STA must be uniform and granular with no material greater than minus 3 -inch . INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction . The OVVTS observation should be performed before backfill . after placement of 0VVTS components . Septic tanks, distribution devices, pumps , dosing siphons, and other plumbing , as applicable . must also be observed .
