It has come to our attention that this property is being considered for a cat shelter. Per the application, the home will no longer be utilized as residential living quarters. The home will now be used as an animal shelter only with volunteers coming in daily to care for the animals . Longs Peak Water District does not have any issue with the changed use of the dwelling, and can adequately serve the domestic water service demands to this address . Keep in mind, this tap will not adequately serve any fire sprinkler or suppression system if required by the fire authority. Additional off-site infrastructure would be needed for any fire-flow demands. Should you have questions or need additional information, please contact me . Best regards, tit a Gary Allen General Manager Maxwell Nader From: Gary Allen < g .allen@tpwd .org > Sent Monday, July 20, 2020 12:40 PM To: Maxwell Nader Subject: Re: Cat shelter being permitted at 1131 HWY 66 Follow Up Flag : Follow up Flag Status: Flagged Caution: This email originated from outside of Weld County Government.

We do however serve 1132 HWY 66 and that tap is owned by Longmont Friends of Cats . I am hopeful this is the same property and there isn't any issue with the letter . The account number for this address is 170003. am sorry for the confusion with the actual property address, and hope that doesn't cause any confusion . Please let me know if you need anything further.

EXISTING CONDITIONS/PROPOSED CONSTRUCTION The site is currently occupied by an existing residence and an outbuilding. The plan is to install a new onsite wastewater treatment system that will be designed and constructed to accommodate the existing 3-bedroom residence. Please note that this residence is going to be used as a cat rescue facility. However, as we will demonstrate, the wastewater flows for that proposed use are less than those of a 3-bedroom residence, This is being designed this way in case it is ever converted back to a residence, inwhich case the system would be adequate. The area in which the soil treatment area will be constructed is locatedeast of the existing residence . This area is gently sloping, with a slope of about 2%, which appears to be generally to the south. SOILS CONDITIONS Two test pits were completed adjacent to the area proposed for the new soil - treatment area. The test pits revealed a topsoil layer approximately 1 foot thick, underlain by clay, which continued to the full depth of the test pits of just over feet GROUNDWATER Neither groundwater nor signs of a seasonal groundwater table were noted in the test pits, to the full depth of the test pits of approximately 8 feet. Therefore, groundwater will not be a design or construction consideration. PERCOLATION TESTS Percolation, tests were not performed for this design. VISUAL, TACTILE AND MECHANICAL ANALYSIS We performed visual, tactile and mechanical analysis of the proposed soil absorption zone, which is the layer below the topsoil at the approximate 2 to 6 foot level. The visual analysis revealed that the material was clay. The tactile analysis confirmed the results of the visual analysis and determined the soil to be clay with a USDA soil structure shape of granular and a USDA soil structure grade of moderate. We also performed a mechanical analysis to determine the approximate proportions of silt, sand and clay. We determined that the soils were approximately 18% silt, 2% sand and 80% clay. Based on this determination, we classified the soil according to the USDA soil texture chart. Using this chart, the soil was determined to be clay. Therefore, all of these indicate that the use of a soil type 4 is appropriate for this design. LONG TERM ACCEPATANCE RATE (LTAR) DETERMINATION The long term acceptance rate (LTAR) was selected by use of Table 30-10-1 in the Weld County Health Department regulations. This was determined to be 0.20 gallons per day per square foot. WATER SUPPLY • The water for this residence is supplied by a water district. There are no known water wells in the area. Therefore, offset between wells and the soil treatment area should not be a design consideration. PRELIMINARY INVESTIGATION Prior to doing the field investigation we conducted research including review of the mapping, review of aerial photos of the property, information available from the Weld County Assessor's website, information available from the Weld Health Department,artrnent, review the USDA soil mapping (a copy of which is attached to the report) and review of soils engineering and septic system design reports that we had .completed nearby. y Our review of the information above revealed that no major issues related to construction of this new very clayey stem should be encountered other thane y c y y soils. Page 2 DESIGN OF THE PROPOSED SYSTEM Details of the proposed system, including a site plan and a typical section of the proposed onsite wastewater treatment system, are shown elsewhere in this report. The design of the sewage disposal system is based on criteria established by the . Weld County Health Department Individual Sewage Disposal Regulations. The • proposed design provides for an absorption bed as part of the septic system. The system design is based on the following assumptions. The residence is to be remodeled for use as a cat rescue facility. The proposed use was described to me as . . . "Up to 25 cats may be housed in die dwelling. Lip to 30 cats may be housed outside in a fenced-in area if a colony needs a place to be held . Up to 5 volunteers will be working onsite at one time with a maximum of 10 volunteers per day. So up to 10 volunteers and 1 part-time employee per day, and twice a month a gathering of up to 15 volunteers may occur on site for training purposes." We discussed this with the health department, who told us that we can assume 1 gallon per cat per day (total of 65 cats, maximum, or 65 gallons per day). For the volunteers, we assume a maximum of 10 part time persons, and we assume . approximately half time or the equivalent of 5 full time persons, at 20 gallons per . person per day, for a total of 100 gallons per day. For the 1 part time employee, we am assuming I full time employee at 20 gallons per day for a total of 20 gallons per _day. Finally, the once a month meeting of 15 volunteers, I am assuming 5 gallons per day per meeting attendee or a total of 75 gallons per day . Therefore, the total wastewater is going to be approximately 260 gallons per day. We discussed this with the client, and it was decided to design for the greater potential use, as a 3-bedroom residence, which would have a design wastewater flow of 450 allons per day, 'ust in case this ever reverts to residential use. Base Size Calculation 1 . Three bedrooms 6 persons 2 persons per day for the first 3 bedrooms 2. Daily flow 75 gal / person / day 75x6 450 gallons per day a Page 3 . Design LTAR = 0.20 gal / day / sf The required base surface area = 450 / 0.20 of the absorption bed _ 2250 square feet Table 10-2 Size Adjustment We are designing this system utilizing gravity delivery and an absorption bed . The Table 10-2 size adjustment multiplier for this combination is 1 .2. The. required surface area of = 2250 * 1 .2 the absorption bed utilizing gravity delivery 2700 square feet Table 10-3 Size Adjustment We are designing this system assuming that rock will be used for the distribution media. The Table 10-3 size adjustment multiplier for this is 1 .00 . The required surface area of = 2700 * 1 .00 . the absorption bed utilizing rock distribution 2700 square feet Therefore, the total required field area has been determined to be 2700 square feet. For this site we recommend a soil treatment area that is 30 feet wide by 90 feet long. This provides a total area of 2700 square feet. OTHER DESIGN CONSIDERATIONS TION A 1000-gallon, two-compartment septic tank is required for a 3-bedroom residence . We recommend that the existing tank be abandoned and a new tank installed . The area proposed for the new soil treatment area is slightly downslope from the office and we believe that gravity flow should be possible. We recommend that the installer expose all the components and shot elevations prior to the construction. If it is found that gravity flow to the new field is not possible then a lift station will be required . Attached to this report is a drawing that illustrates our recommendations for the lift station, if necessary. Page Please note that the sewer linewill have to cross a very small irrigation lateral. By code, the sewer line must be encased to a minimum distance of 10 feet on either side of this lateral. This lateral appears to terminate just north ofwhere the crossing would be , An alternative would be to abandon this small lateral . Please note that we have sited the new soil treatment area at a distance of over 25 feet from this lateral. Please note that this is a replacement system and, as such, the soil treatment area is not limited to a width of 12 feet. Since this is a fully infiltrating field it may be backfilled with the better portions of the site soils . Special attention is required to assure that the proper backfill and site grading is � p p completed . These items are extremely important to assure satisfactory long-term performance of the field . All offsets should be per the Weld County regulations; other than the distances to setback objects indicated on the design documents, no other objects requiring setbacks from the proposed onsite wastewater treatment system (OWTS), as indicated in Tables 30-7- 1 and 30-7-2 of Chapter 30 of the Weld County Code, have been located or observed during our preliminary investigation, reconnaissance or detailed soil investigation. We recommend that the surface of the soil treatment . area be seeded after installation of the system. We recommend using a seed mix such as "Foothills Pasture" or "Prairie" mixes that are available at seed stores. These do not require irrigation and develop growth of 10 to 15 inches high, No automatic sprinkler system should be installed over the soil treatment area. • Page 5 pi SPECIFICATIONS FOR INDIVIDUAL SEWAGE DISPOSAL SYSTEM ABSORPTION TYPE CODES AND REGULATIONS The minimum standards required herein shall not be construed as removing the necessity for compliance with any regulations established by the building and health authority having jurisdiction when such regulations provide for higher standards than contained herein. Where these Drawings and Specifications are more restrictive - than local codes and regulations, the Drawings and Specifications shall be followed. Notes on the drawings and I or requirements of the design section of the report shall take precedence over the standard Drawings and Specifications. CHANGES IN OR DEVIATIONS FROM DRAWINGS AND SPECIFICATIONS Changes in the Drawings and specifications may be permitted according to the following provisions: 1 . The change does not violate any code or regulations. 2. The request for a change is submitted to the Owner or authorized representative of the Owner prior to construction. 3. The change is approved by the Owner or his authorized representative. 4. The change is approved in writing by the Engineer and an authorized representative of the Health Department. MATERIALS Materials used in the construction of the septic tank and absorption field shall be durable, new, sound, and not subject to corrosion. Gravity pipe and absorption field pipe shall be 4-inch, minimum, unless otherwise indicated . PIPING The building sewer leading to the septic tank shall be laid with a minimum fall of 1 / 8-inch per foot and preferably 1 / 4-inch per foot. Bends should be limited to 45-degree "L's" or long sweep quarter bends. Sewer pipe shall be gasketed PVC gr avity pipe ASTM D3034 (SDR-35 ) or solvent weld PVC ASTM 2729 sewer p' P (SDR-35) . The absorption field piping shall be perforated PVC ASTM 2927, or white rubber sewer and drain pipe, Spec. CS-228-61 or Fed. Spec. WWP 00380 having 1000 pound crushing strength. Between each trench or bed in the case of a serial-type system, or at distribution pipe bends, standard pipe fittings which will form Page 6 rigid watertight joints shall be used . Pipe in beds and trenches shall be installed level. The terminal ends of all lines shall be capped unless looped or air vented . At least one capped inspection pipe shall be provided in each trench or section of the bed . If small diameter pump line plastic pipe is required, it shall be PCV pipe, minimum class 200. All pipe, pipe fittings, and pipe joints shall be in accordance with the Uniform Plumbing code, and the manufacturer's recommendations. PUMP For this system we recommend a Gould, 0 .50 horsepower pump, model EP0511, or equivalent if a pump is necessary. ABSORPTION FIELD The absorption field shall be constructed in accordance with the lines, grades, and details given on the drawings. There shall be undisturbed earth or compacted fills retaining all septic tank effluent. All fills or dikes are subject to inspection and approval by the design engineer. Open trenches shall be protected from surface runoff to prevent the entrance of silt and debris. All smeared or compacted surfaces of the trench or bed shall be raked to expose the natural texture of the soil. All loose material shall be removed from the trench before the gravel is placed . Over-compaction of the absorption field by vehicular traffic or other means shall be prevented . Gravel for the absorption bed shall be washed gravel; minimum size shall be 1 / 2-inch and maximum size shall be 2-1 / 2 inches. BACKFILLING AND SITE GRADING All major grading shall be accomplished before construction of the sewage disposal system is begun. Backfill around the septic tank shall be with moist soil p g p hand tamped sufficiently to prevent future settlement. Positive drainage from. and around the bed must be provided by sloping, mounding, ditching and beaming as shown on the drawings. Page 7 MAINTENANCE AND OPERATION CLEANING Septic tanks should be cleaned before too much sludge or scum is allowed to accumulate. If either the sludge or scum approaches too closely to the bottom of the outlet baffle, or other device, particles will be scoured into the disposal field andwill clog the system. Eventually, when this happens, liquid may break through to the ground surface and / or the sewage may back up in the plumbing fixtures. When a disposal field is clogged in this manner it is not only necessary to clean the tank but it also may be necessary to construct a new disposal field . Tanks should be inspected at least once a year and cleaned when necessary. Cleaning may be necessary every two to five years. Although it is difficult for most persons, actual inspection of sludge and scum accumulations is the only way to determine definitely when a given tank needs to be When a tank is inspected, the depth of sludge and scum should pumped . p p be measured in both compartments. The tank should be cleaned if either (a) the bottom of the scum mat is within approximately 4 inches of the bottom of the outlet baffle, or (b ) sludge comes within 8 inches of the bottom of the outlet baffle. Scum may be measured with a pole to which a flat board has been attached, or with any device that can be used to feel out the bottom of the scum mat. The pole is forced through the mat, then turned and raised until resistance from the bottom of the scum is felt. With the same tool, the distance to the bottom of the outlet baffle can be found. There are firms which conduct a business of cleaning septic tanks. The yellow pages may be consulted to obtain this service. Cleaning is accomplished by pumping the contents of the tank into a tank truck. Tanks should not be washed or disinfected after pumping. A small residual of sludge should be left in the tank for seeding purposes. When a large septic tank is being cleaned, care should be taken not to enter the tank until it has been thoroughly ventilated and gases have been removed to prevent explosion hazards or asphyxiation of the workers. CHEMICALS In general, the addition of chemicals to a septic tank is not recommended . The p' functional operation of septic tanks is not improved by the addition of disinfectants or other chemicals. Some 1,200 products, many containing enzymes, have been placed on the market for use in septic tanks, and extravagant claims have been made for some of them. As far as is known, however, few have proved of advantage in properly controlled tests. Frequently, however, the harmful effects of ordinary household chemicals are over-emphasized . Soaps, detergents, bleaches, drain cleaners or other material, as normally used, will not have appreciably adverse effects on the system . However, as both the soil and essential organisms might be susceptible to large doses of chemicals and disinfectants, moderation, should be the axle. Page 8 g Waste brines from household water-softener units have no adverse effect on the action of the septic tank, but may cause a slight shortening of the life of a disposal field installed in a structured clay-type soil. MISCELLANEOUS Roof drains, foundation drains, and drainage from other sources producing large intermittent or constant volumes of clear water should not be piped into the septic tank or disposal field . Such large volumes of water will stir up the contents of the tank and carry some of the solids into the outlet line; the disposal system following the tank will likewise become flooded or clogged and may fail. Drainage from garage floors or other sources of oily waste should also be excluded from the tank. Disposal fields of either the absorption or evapotranspiration type must not be used for driveways or parking, or any use which might overcompact the area. Drawings and designs showing the location and other information regarding the septic tank and disposal system should be retained by the property owner.
