Date: 8-1-22 Subject: Nguyen Cluster PUD (Case No. PUDK21-0004) CWS File #22-130 The purpose of this memo is to outline the proposed uses and water demands for the Nguyen Cluster PUD. The property is a 122.64 -acre parcel located in the South 1/2 of the North 1/2 of Section 33, Township 1 North, Range 66 West, 6th P.M. in Weld County. This location is northeast of the City of Brighton and the Brighton Lateral Ditch runs through the center of the property. This property is not being proposed for development as a "subdivision" per Section 30-28-101(10)(a), C.R.S. but as a cluster development under C.R.S. 30-28-401 through 404. Two requirements of a cluster development are: 1. At least 2/3 of the original tract be contiguous open space and cannot be developed for at least 40 years. 2. The density of residential lots cannot exceed more than one lot per 17.5 acres. If these requirements are met, the Division of Water Resources will issue one exempt well permit per lot. The proposed development will have 100.7 acres of open space on the west portion of the property. This is platted as an agricultural lot and will stay undeveloped for a minimum of 40 years. This not only meets but exceeds the required 81.8 acres (2/3 x 122.64 acres) of open space. The property will also meet the required density of less than 17.5 acres per lot. The six lots will range from 3 to 5 acres in size. The water supply determined by the Division of Water Resources rules for cluster developments equates to 122.64 acres divided by 35 -acre increments, rounded down for issuing a residential well permit (GWS- 44). The calculation is (122.64/35 = 3.5 acre-feet), rounded down is 3 acre-feet. For the proposed six lots, the allocation will be 0.5 acre-feet per lot. This water can be used for both indoor and outdoor uses. Outdoor uses may include irrigation as well as watering of domestic animals. 4750 Larimer Parkway, Unit 101 • Johnstown, CO 80534 • (T) 970.223.3706 • (F) 970.223.3763 • www.clearwatercolorado.com Page 2 of 2 Indoor use for a single-family home is conservatively estimated at 0.3 acre-feet per year. As homes continue to use more efficient, low water -use fixtures, this amount is decreasing. Using the 0.3 acre- feet for indoor use, this leaves 0.2 acre-feet for outdoor use. The estimate for domestic animal use is determined by the formula that 100 head of livestock requires 1.35 acre-feet of water. This equates to approximately 0.01 acre-feet per animal. The estimate for outdoor irrigation is 0.05 acre-feet for every 1000 square feet of lawn. So, by example, the first option for a lot owner with no livestock can irrigated approximately 4,000 square feet of lawn (0.2 acre-feet/0.05 acre-feet per 1000 square feet of lawn). Another option would be to irrigate 3,000 square feet of lawn and have up to five domestic animals. In our opinion, 0.5 acre-feet per lot is sufficient to meet the indoor use for a single-family home plus outdoors uses including irrigation up to approximately 4,000 square feet of lawn with no domestic animals or a combination of irrigation less than 4,000 square feet and the watering of domestic animals. We want to be clear that these are not hard limits and are general estimates based on our expertise and experience to show the 0.5 acre-feet per lot of water supply is sufficient. The Division of Water Resources will require totalizing flow meters on each well and the Division's requirement will be that the 0.5 acre-feet annual limit is not exceeded. The uses within the 0.5 acre-feet per year is flexible depending on the lot owner's desires. This memo does not provide any information on the potential yield from the wells once drilled. A well driller will assist with that in the future. The wells will be limited to 15 gallons per minute each. © Clear Water Solutions, Inc. 41) DNR COLORADO Division of Water Resources Department of Natural Resources Bedrock Aquifer Evaluation Determination Tool Denver Basin Aquifers - Tract of Land Determination Tool Applicant: Lisa Nguyen Annual Appropriation for tract (Acres): 5 Receipt Number: Evaluated By: Doug Seely Warning!

The issuance of this permit does not ensure that no injury will occur to another vested water right or preclude another owner of a vested water right from seeking relief in a civil court action. 2 The construction of this well shall be in compliance with the Water Well Construction Rules 2 C.C.R. 402-2, unless approval of a variance has been granted by the State Board of Examiners of Water Well Construction and Pump Installation Contractors in accordance with Rule 18. 3 Approved pursuant to CRS 37-92-602(3)(b)(I I)HA) as the only well on a tract of land of 122 acre(s) described as that portion of the S1/2 of the N 1/2) Sec 33, Tw p. 1 North, Rn g. 66 West, 6th P.M., Weld County, more particularly described on Exhibit A in the well permit file. 4) The use of groundwater from this well is limited to fire protection, ordinary household purposes inside not more than three (3 single family dwellings, the watering of poultry, domestic animals and livestock on a farm or ranch and the irrigation of not more than one (1) acre of home gardens and lawns. 5. Production is limited to the Laramie -Fox Hills aquifer which is located approximately 885 feet below ground surface and extends to a depth of approximately 1220 feet. In accordance with Rule 10.4.8 of the Water WeLL Construction Rules, plain steel casing must be installed and grouted from the top of the permitted production zone up to at least ten feet above the base of the surface casing., or to the depth required by Rule 10.5.2.1, if no surface casing is installed. (NOTE: If coals and/or carbonaceous shales are encountered in the borehole, plain casing and grout should be installed through these intervals to exclude poor quality water from entering the well,) 6j The pumping rate of this well shall not exceed 15 GPM. 7) The return flow from the use of this well must be through an individual wastewater disposal system of the non -evaporative type where the water is returned to the same stream system in which the well is located, 8 This well shall be constructed not more than 200 feet from the location specified on this permit. 9) ADVANCE NOTICE REQUIRED - Pursuant to Construction Rule 6.7.2.1 (2 CCR 407-2), licensed or private drillers and pump installers must provide advance notification to the State Engineer prior to each of the following for this well: the start of well construction, the initial installation of the first permanent pump, and the initial installation of a cistern connected to the water well supply system. Any change in the date of construction /installation must be re -noticed prior to the activity. Information regarding the notification process and a link to the electronic notification form can be found on the Division of Water Resources we bsite NOTE: This well is withdrawing water from a non-renewable aquifer. While the withdrawals from this aquifer are administered based on a 100 year aquifer life, water level declines may prevent this well from diverting the permitted amounts for that 100 years. NOTE: To ensure a maximum productive life of this well, perforated casing should be set through the entire producing interval of the approved zone or aquifer indicated above.
