G?- Trilogy Development, Inc. 9839 W. Cable Car St, Suite 100 Boise, ID 83709 1119 E. State Street, Suite 210 ♦ Eagle, Idaho 83616 ♦ Tel.: 208-938-0013 www.baileyengineers.com Summary Pump Station Design Point:560 gpm @ 160 TDH Pump Station Average Calculated Pump Demand:217.0 gpm [197.0+20] Pump Station Peak Calculated Pump Demand: 250.3 gpm [230.3+20] Total Available Water Rights: 539 gpm [1.45 cfs] Water Supply The property has access to 59.87 acres of water from New York Irrigation District(see attached memorandum from HDR, dated July 5, 2022. Per HDR report,these shares provide a delivery of 539 gpm.The water is delivered from the Farr Lateral, located along the site's northern boundary. Water Demand The irrigation demand for Reveille Ridge Subdivision was determined first by analyzing the total irrigable area within the pump station's service area.The preliminary plat was used to estimate total irrigable area for each lot. The peak project water requirement was determined using the standard Boise Project Board of Control Equation, applying 0.33 inches of water per day over the sum of the building lot area, applied within a 12-hour period.The same demand flow rate of 0.33 inches of water per day was used to calculated the 'average demand flow' over all irrigable acreage and utilizing the entire available irrigation time of 24 hours per day.A demand of 20 gpm has been added to both the average and peak demands to account for the Clemons screen for pump sizing calculations, although water used to clean the screen will not leave the system. Delivery to Pumping Plant Irrigation water to the pump station is delivered from the Farr Lateral located on the north side of the development property. In the initial phase(s) of development,water can continue on its historic route directly to the on-site pond. When future phases are developed the inflow line will be tiled to the screen box where check boards will raise the water level in the pond. A 12" headgate is shown in the screen box to hold water in the screen box and allow operation of the pump station without filling the pond if it proves necessary due to timing. Screen Box The concrete screen box contains a Clemons CW-800 screen.The screen requires 20 gpm to operate; this demand has been added to that of the pump station.The screen is a not a consumptive use of the water; it can be recycled back into the screen box.The screen is located in the screen box and feeds directly to the pump station. Check boards in the screen box will control the water level in the adjacent pond.The Clemons screen has been designed with a minimum of 2-ft of clearance on all sides. Wet Well The concrete wet well will have a diameter of 48".The total depth has been designed at 14.5 feet from top of wet well to top of floor(to be verified by pump supplier),with 12-ft of water depth. Manhole steps will be provided for maintenance inside the wet well. Pumps A total pump capacity of 560 gpm at 160 TDH must be provided. Plans show two (2) submersible turbine pumps [each 280 gpm at 160 TDH] but vertical turbines are acceptable if desired by developer. A jockey pump will be provided if determined to be necessary by the pump supplier. Hydraulic Analysis A hydraulic analysis was performed for the Reveille Ridge pressure irrigation network using WaterCAD software. As the pump station is located directly adjacent to the central area of Ph 1, the analysis has been performed for only the buildout condition. A pressure irrigation demand equal to the peak calculated demand of 560 gpm was placed at nodes throughout the development site (w/20 gpm demand at the screen location). Demands were spread throughout the system with an attempt to put them at hydraulically remote locations (within the site's interior, higher elevations, and far from the pressure irrigation pump station). The system utilizes pipes with a minimum diameter of 4" and a maximum diameter of 8". Junction elevations were provided using the existing site topography and the program's Trex functionality. Throughout the system, no large sources of head loss are seen, with no velocities exceeding 5 ft/s and no junctions with low pressure. Reports are attached for the pipes, junctions and the pump definition in Appendix B. Watering Schedule A watering schedule has not been provided for this development at this time for the following reasons: 1) There is a large differential between the site's average (197 gpm) and peak calculated flow rates (230.3) and the available water right(560 gpm). Pumps are designed for the larger,water right flow rate. 2) The site utilizes the existing wet pond for flow equalization.The top of screen sits 36" below the max water level in the pond and can operate effectively with 24" of water cover. Over this 12"of'active'volume,there is approximately 60,000 cu ft of water available in the pond for equalization. -Approx equalization at water right: 13.5 hours -Approx equalization at peak demand flow: 32.9 hours -Approx equalization at average demand flow: 38.5 hours A watering schedule does not impact design criteria can be provided at a later date if deemed necessary or operational/usage problems arise.

RE: Cool Water Creek Subdivision Water Right Analysis Summary 1. No private water rights exist on the property. 2. Manie Investments owns 59.87 acres of New York Irrigation District(NYID)water. These shares provide 9 gpm/acre for a total delivery of 539 gpm. 3. Municipal water may be provided by a stand-alone ground water system or connection to an existing municipal provider; either the City of Kuna or City of Meridian. The City of Meridian has a water main and existing services in the local vicinity to the development. 4. The existing water storage use requires additional water right authorization.A new water right application should be filed to authorize irrigation storage, aesthetic storage uses to cover capacity and consumptive losses. 5. With additional water right authorization, existing well(s) on the property can be used to divert ground water to the storage pond for irrigation storage and consumptive losses for aesthetic storage uses. Introduction This memorandum provides a review of the existing water rights and water delivery associated with a 59.957-acre property known as the Coolwater Subdivision (Property)that KB Home Idaho, LLC is considering for development of a residential subdivision. The Ada County Assessor office confirmed the Property is currently owned by Mamie Investments Co., LLC under two parcels; S1405417310 (19.891 ac) and S1405131304 (40.066 acres). As shown in Figure 1, the Property is located at 7355 S Eagle Road, south of Lake Hazel Road, Ada County. Details of the evaluation are provided in the following sections. hdrinc.com HDR I SPF,300 E.Mallard Dr.,Suite 350,Boise,ID 83706 (208)872-9500 r Ia... +9a1�v Laf.n"fa.- FL9 L:°BYhF 4 Lfoki Hid Lh S1 5131 04 E4.a�%L,qr fi.;u�r L.

WATER RIGHTS A text-based search of the online IDWR water rights database identified no privately owned water rights associated with the Property. HDR Engineering, Inc. Page 2 KB Home Idaho, LLC EBS No. 10346718 Cool Water Creek Subdivision WR Analysis The Property is currently outside of any municipal boundary but is within both the City of Meridian and City of Kuna municipal water rights place of use. Communication with both cities confirmed that the Property currently has no hook up to a municipal water system. New York Irrigation District (NYID) NYID confirmed that the Property is assessed 59.87 acres of irrigation under Account No. 216- 002-00 in the name of Mamie Investments Co., LLC. Water is delivered to the Property via New York Canal, through the Farr Lateral which runs along the Properties northeast border. The Property has rights through two gates. These gates labeled 870 and 871 are found in close proximity to each other on the west side of Eagle Road, where the lateral crosses the road. Currently,the Farr Lateral delivers water to the Property through headgate number 871. Gate 870 has not been used to deliver water to the Property since the land was subdivided some time ago. Water users make a call for water no later than 6 a.m. the day prior to delivery. NYID accounts for the water that is delivered through a 2-foot Cipolletti weir. Once 3.75 acre-feet(af)of water per acre is delivered in a season, users can call for additional water at a cost when water is available. Water is regularly available at these gates and not subject to rotation or schedule. The lateral carries a significant amount of water adequate for the subdivision's irrigation demand. Deliveries are sufficient to irrigate most agricultural crops in the Treasure Valley and can be used for turf and landscape irrigation after residential or commercial development of the land. NYID's most senior water rights carry Basin 63 step-down curtailment conditions.Any other rights that do not carry such condition will be curtailed through priority. This makes most of the district's water rights relatively junior-priority, and reliant on reservoir storage. During drought years, the NYID deliveries may be significantly reduced. The 2021 Water District 63 accounting reported the New York Canal began diverting water into the canal April 1401, 2021, and continued to deliver water through September 15'h, 2021.A recent conversation with the ditch rider reported that a target shut off date for 2022 was mid-August before the significant rain fall and cool spring experienced across the basin. With the recent precipitation, that shut off target has been moved back to mid-September. Seasons with more available water will deliver water into October. The possibility of short surface water supplies from NYID during drought periods adds value to privately-owned supplemental ground water rights. HDR Engineering, Inc.

The Property is within the place of use of these rights, however, the nearest connection point to this system is the intersection of Hubbard and Locust Grove Road (2.4 miles) or Linder and Columbia Road (3.4 miles). The City of Meridian diverts ground water from wells under two water rights that overlap the property (63-12039 and 63-31281). Connection to the City of Meridian is considerably closer. A map of the city's municipal system (Appendix A) shows a water main delivers water to a fire hydrant 1,200 feet north of the property boundary on Eagle Road, south of Lake Hazel Road. This main serves The Keep subdivision immediately north of the Property. The property is within both cities water rights, so the place of use (service area) would not need to be expanded. HDR Engineering, Inc. Page 4 KB Home Idaho, LLC EBS No. 10346718 Cool Water Creek Subdivision WR Analysis Access to existing public water systems is limited to either the City of Meridian or City of Kuna. Connection to the City of Meridian will require the least amount of infrastructure costs, right of way, easement, etc. New Water Right Permit for Development Options for providing water service to the proposed Cool Water Creek development include (1)connecting to an existing public water system, or(2) permitting and constructing a new stand- alone public water system (PWS)to serve the development. The permit to authorize a stand-alone system would identify the property as the place of use, identify future well locations as points of diversion, and request a ground water diversion rate based on anticipated water demands. A stand-alone public water system could either be owned and operated by the development or transferred to the City for operation once complete. The requirements for the water system would essentially be the same whether the water system was owned and operated by the development or City. The public water system must meet the requirements of the Idaho Rules for Public Drinking Water Systems(IRPDWS). This same system could be designed to provide fire protection and supplemental irrigation. The following infrastructure for a new PWS would be needed: • Two PWS wells, each with a minimum capacity to meet maximum daily demand plus supplemental irrigation. The wells would be located on dedicated well lots with a minimum of 50 feet of separation to adjacent properties. • Storage would be required to meet fire, equalization, operational, and emergency standby storage requirements. If there is adequate well capacity available to meet peak hour demand plus fire flow, then storage would not be needed unless required by the City. • Well house(s)for mechanical and electrical equipment. • If storage for fire flow and/or potable water is needed, then a booster pump station will be needed to provide the required flow rate and pressure. The booster pump station must be equipped to meet maximum daily demand with fire flow with the largest pump out of service and be equipped with backup power. • Water treatment if source water exceeds primary drinking water standards. A stand-alone public water system would need to be permitted through IDEQ and a new water right permit for municipal use will be needed. If a stand-alone system is to be pursued, then a more detailed analysis of water system requirements can be performed once more detailed development plans are available. To date there have not been discussions with either city identifying their requirements for a stand- alone water system. However, it is reasonable to defer to the Idaho Rules for Public Drinking Water Systems (IRPDWS; IDAPA 58.01.08) to outline the expected requirements for the new public water system. PRESSURE IRRIGATION DEMAND HDR's experience with typical residential developments indicates approximately 40 to 60 percent of the total project area remains irrigable after development. Initial plans for this KB Homes HDR Engineering, Inc. Page 5 KB Home Idaho, LLC EBS No. 10346718 Cool Water Creek Subdivision WR Analysis development indicates 171 lots with an average lot size of 0.125 acres per lot, suggesting a 40 percent irrigated area suitable for planning purposes. This approximate 60-acre residential development will require irrigation supplies for approximately 24 acres, which includes several community amenities, a multi-use pathway and common area space.This range can be narrowed with further information regarding irrigated open space, lot sizes, and other items influencing irrigated area. For planning purposes, the water entitlement for 60 acres offers 9 gpm per acre, which is 540 gpm (1.2 cfs) over a 24-hour period. Common residential irrigation schedules range between 1:00 a.m. to 9:00 a.m., which is only 8 hours. For 24 acres over a 24-hour period, a system must deliver a rate of 0.48 cfs. The entitlement of 1.2 cfs offers the ability to apply 0.4 inches of water to 24 acres in an 8-hour period. To optimize the use of surface water and provide the subdivision the most robust system, an irrigation storage pond can be used to receive water 24-hours per day to make water available whenever it is needed. STORAGE REQUIREMENTS The latest plans sent to HDR included an existing pond in the southwest corner of the Property. A storage system can provide water when demand exceeds supply, which is currently limited to 1.2 cfs. A pressurized system can utilize the storage water to charge the system, bringing the irrigation water to sufficient pressure. This section summarizes the space requirements for a pond and pump system should one be required. Storage Water Rights Boise Project Board of Control and NYID water rights do not recognize irrigation storage or irrigation from storage beneficial uses. There are no storage water rights associated with the property since all the agriculture irrigation is accomplished by live water flows. IDWR Administrative Memorandum # 73 states that the 24-hour fill allowance (aka the "24-hour rule")defines the volume of water impounded without a storage component is equal to the volume of water capable to be diverted by the irrigation diversion rate in a 24-hour period. The Property can receive up to 1.2 cfs from NYID, capable of producing 2.4 acre-feet in a day. Using 2021 satellite imagery, a pond surface area of 1.5 acres is measured. Depth of the pond is unknown. If the maximum depth of 10 feet is assumed, using a slope gradient of 40%, capacity of the pond is calculated to be six acre-feet. If consumptive losses such as seepage and evaporation are considered, the storage of water in this pond will require additional water right authorization. Diversion to and from Storage Pond Inflow potential into the pond from NYID is 775,600 gpd or 2.4-acre feet. Based on satellite imagery and assumed max depth of ten feet, the existing storage pond on site has a capacity of HDR Engineering, Inc. Page 6 KB Home Idaho, LLC EBS No. 10346718 Cool Water Creek Subdivision WR Analysis 6 acre-feet. This volume is sufficient to meet the daily irrigation demand of the proposed development. A pump station should be constructed with the capability to pump the maximum calculated demand plus twenty percent. For 24 acres, this instantaneous flow rate would be 1.44 cfs (0.06 cfs/acre), or 650 gpm. A system with the expected irrigation use of this project (24 acres) should anticipate a maximum flow rate of 1.74 cfs, or 650 gpm from the pond. If the pond is used as an aesthetic feature of the development, water will be in the pond year- around.A new water right will be required to authorize the pond and storage of water year-around. Drainage Gradual elevation slopes from north to south on the property. Currently, an open ditch is used to drain irrigation water from east to west through a drain ditch along the south border of the property (Figure 2). This drains water from both the KB Homes' property as well as neighboring lands and therefore must preserve the ability for drainage past the Property. Any storage use that is developed should be designed to overflow water to this drainage ditch. Water currently collects towards the southwest corner of the property. Land use at this location is undeveloped. Because there are no delivery requirements to other water users downstream of the property, future development plans should consider filling this area to ensure flooding of private property does not occur. KB Homes can determine the optimal route for drain water. Potential Pump and Storage Location With plans to maintain the existing pond, an irrigation lift station should be constructed nearby to provide irrigation water to the development. Elevation slopes from the NE corner(-2,755 ft msl) to the SW corner(-2,740 ft msl). With only approximately 15 feet of lift, a single lift station at this site is capable of providing irrigation water to all areas of the development. Water delivery from Gate 871 (Figure 2) can be piped to the pond and KB Homes has the flexibility to place an irrigation system anywhere that is convenient to the development plans. Existing Ground Water Resource A well on the property currently serves a single-residence and commercial use for a window blind company. Idaho Code§42-227 states that the excavation and opening of wells and the withdrawal of water therefrom for domestic purposes shall not be subject to the permit requirement. Domestic use is defined by Idaho Code §42-111 as water for a home and up to half acre of irrigation or any other use not to exceed 0.04 cfs and 2,500 gallons per day. The existing well on site was not constructed to public drinking water standards and may not be used to deliver in-home water to the development. With an appropriate water right, this well may be used to divert supplemental irrigation water to the pond or be used to maintain consumptive losses associated with aesthetic storage, assuming the well is in a convenient location. RECOMMENDATIONS There are several design options to consider for the future PI System: HDR Engineering, Inc. Page 7 KB Home Idaho, LLC EBS No. 10346718 Cool Water Creek Subdivision WR Analysis • Take direct delivery of surface water from NYID without using a regulating storage pond or any other supplemental water. Water may be delivered to the Property on a schedule to which the homeowners will be coordinated. Water not pumped by the PI system would either pass into the drain or the existing pond. Problems with this option include early system shutdown if surface water supplies are curtailed in drought years and potential inability to meet peak hour demands. • Utilize the existing storage pond that receives NYID surface water to meet peak-hour irrigation demands. Water not pumped by the PI system would remain in the pond to serve future irrigation demand and aesthetic storage use. This option provides a more reliable and efficient irrigation system for the subdivision and homeowners can irrigate at any time of the day. • Develop ground water as a supplemental irrigation source to NYID surface water. This is usually a recommended option to ensure a robust PI system. An Application for Permit filed with IDWR would recognize either a new well or existing well on the property and permissible place of use to secure supplemental irrigation use to the property. With an existing storage pond on the property, the ideal irrigation system would receive NYID water 24 hours a day into the storage pond to allow irrigation to occur at high rates without a rigid schedule or rotation. To allow optimum utilization of common areas and yards, and to reduce the need for an enforcement of irrigation schedules or rotation, it is better to assume an irrigation window of 6 to 8 hours and provide PI system pump station and distribution capacity of approximately 650 gpm (24 acres irrigated at a rate of 0.06 cfs/ac). A supplemental irrigation water right would be appropriated to use the existing well or a new well to provide should-season irrigation flow and pond maintenance. Prior to development of the Property: • Prepare an irrigation master plan for the Property. The master plan should consider post-development irrigated area, peak-daily water demand volume, and peak-hour irrigation demand. • If KB Homes wants to develop a supplemental irrigation system,then file an Application for Permit for an irrigation pond and well system. Upon or during development of the Property: • When individual lots are sold in the future, conveyance deeds should include language indicating the water rights have been retained and will be assigned to an HOA upon development completion. This could also be accomplished through a recorded conveyance. It should also be included in the CC&R's. HDR can assist with any of the above actions or provide additional ground water research and support upon request. HDR Engineering, Inc.
