E., Engineering Division Manager 1:- SUBJECT: Z-570 Spring Meadows PUD, Olson Brothers LLC COLORADO The Public Works Department has reviewed this PUD Change of Zone request. Comments made during this phase of the process may not be all-inclusive, as other concerns or issues may arise during the remaining application process. COMMENTS: External Roadways: WCR's 42 and 15 are designated as local roads in the Comprehensive Transportation Plan and require 60' rights-of-way. On the final plat, the applicant must indicate the document that created the existing right-of-way or dedicate the right-of-way on the plat. The portion of WCR 42 at the northwest corner of Lot 9 deviates from the quarter section line. At final plat, the existing road location must be verified and a 60' right-of-way established that covers the roadway. Realigning the curves on WCR 42 will not be required. I agree with the conclusions of the Traffic Impact Study dated July 2, 2002, submitted by Matt Delich. The existing traffic counts in the report are consistent with our information and his projections are reasonable. Spring Meadows will increase the traffic on WCR's 15 and 42 approximately 30%. A proposed off site road improvements agreement that will share the cost of future paving, or dust control, proportional to the impact of the development will be required at final plat application. Existing agricultural accesses may be retained for agricultural purposes only. Internal Streets: The geometry of Dove Court and Willow Lane is acceptable. At final plat, roadway construction plans will be required. Page 1 EXHIBIT 2002-0958 Page 2 Z-570 3-04-02 County Code requires all PUD roadways to be paved. The application materials indicate the internal roads will be gravel but also states they will be paved if the County will accept the streets for maintenance. It is presently County policy to accept paved subdivision streets for maintenance. The internal roads should be paved. Landscaping in the intersection sight distance triangles must be less than 3.5' at maturity. Drainage: A Preliminary Drainage Report, dated March 5, 2001, was submitted by Park Engineering Consultants. I agree with the conclusions and recommendations of the report. At final plat application, a final report and plans detailing the construction for drainage facilities will be required. RECOMMENDATION: I recommend approval of the change of zone with the following items to be addressed at the time of final plat application. 1. Determination of rights-of-way on existing County Roads. 2. A proposed off site roadway improvements agreement. 3. Submittal of roadway plans. 4. Final drainage report and drainage plans. PC: Z-570 M:\W PFILES\DREW\Planning\z-570.wpd Memoran urn TO: Chris Gathman, W.C. Planning DATE: March 1, 2002 VI 1 DQ • FROM: Pam Smith, W.C. Department of Public COLORADO Health and Environment CASE NO.: Z-570 NAME: Olson Bros/Spring Meadows The Weld County Health Department has reviewed this proposal. The applicant proposes a 9 lot PUD on 79 acres. The minimum lot size is 1.1 acres with an overall density of one septic system per 8.7 acres does meet current Department policy. It should be noted that Podtburg Dairy is located approximately .75 miles northeast of the site, and Northmoor Acres is located approximately 1 mile northeast of the site. The application has satisfied Chapter 27 of the Weld County Code in regard to water service. Water will be provided by Little Thompson Water District and sewer will be provided by individual sewage disposal systems. A will serve letter from Little Thompson Water District was provided in the application materials. The application has satisfied Chapter 27 of the Weld County Code in regard to sewer service. Sewer is proposed to be provided by individual sewage disposal systems. Preliminary percolation data provided in the Terracon preliminary geotechnical report dated June 5, 2000 indicates that conventional septic systems may be feasible on portions of the site. Some percolation rates were found unsuitable, and shallow groundwater across the site indicates that engineered septic systems will be required. Lots 1 through 3 may be restrictive because of soil and groundwater conditions. Lot 9 has two suggested building sites to preserve the agricultural practices. The Department recommends that septic envelopes be designated on Lot 9 (on the west side because of the size and shape, on the east side because of the gas line and associated easements). The Department recommends approval with the following conditions: 1. Water service shall be obtained from the Little Thompson Water District. 2. Septic areas shall be designated on both building sites of Lot 9. 3. This subdivision is in rural Weld County and is not served by a municipal sanitary sewer system. Sewage disposal shall be by septic systems designed in accordance with the regulations of the Colorado Department of Public Health and Environment, Water Quality Control Division and the Weld County Code in effect at the time of construction, repair, replacement, or modification of the system. The final plat documents for this subdivision were prepared by Alles and Associates, Inc., Job Number: Olson-0102 and dated December 12, 2001. These final plat drawings indicate proposed primary and secondary envelopes for the absorption fields. These envelopes may be movable, provided the envelopes are of equal or greater area, meet all required setbacks,and are documented by an affidavit of correction per Section 24-5-50 of the Weld County Code. The lot owner shall not place any permanent landscaping,structures,dirt mounds or other items that would interfere with the construction, maintenance, or function of the fields in the primary and secondary envelope. 4. Language for the preservation and/or protection of the second absorption field envelope shall be placed in the development covenants. The covenants shall state that activities such as permanent landscaping, structures, dirt mounds or other items are expressly prohibited in the absorption field site. EXHIBIT IZ 5. If required, the applicant shall obtain a storm water discharge permit from the Water Quality Control Division of the Colorado Department of Public Health and the Environment. Silt fences shall be maintained on the down gradient portion of the site during all parts of the construction phase of the project. 6. During development of the site, all land disturbances shall be conducted so that nuisance conditions are not created. If dust emissions create nuisance conditions,at the request of the Weld County Health Department, a fugitive dust control plan must be submitted. 7. In accordance with the Regulations of the Colorado Air Quality Control Commission any development that disturbs more than 5 acres of land must incorporate all available and practical methods that are technologically feasible and economically reasonable in order to minimize dust emissions. 8. If land development creates more than a 25-acre contiguous disturbance, or exceeds 6 months in duration, the responsible party shall prepare a fugitive dust control plan, submit an air pollution emissions notice, and apply for a permit from the Colorado Department of Public Health and Environment. 9. "Weld County's Right to Farm" as provided in Appendix 22-E of the Weld County Code shall be placed on any recorded plat.

Geotechnical and drainage reports were not included in this referral. The site is located on seventy-nine acres of topographically flat land that is currently used for farming. The proposed zoning change will create eight-one to two acre residential lots,approximately twelve acres of common open space and a fifty-four and a half acre agricultural lot which will contain a gas well envelope. The site geology consists of Quaternary-age eolian sand deposits mantling the Tertiary- age Denver Formation. The following conditions were described in the referral and observed during the site visit: 1) Groundwater.Shallow groundwater is evident in this area and may affect excavation and building design at this site. Groundwater conditions should be investigated by a geotechnical engineer and considered in the design on the subdivision. If shallow groundwater is found to be present at the site, basement or crawlspace construction may not be possible. If subgrade construction is desired, it may be required to raise the grade of the building envelope to an elevation above the high water table elevation,as directed by a design engineer. Shallow groundwater may saturate the soils and cause instabilities leading to a lowered bearing capacity for structures at the site. 2) Soils.The eolian sands at this site could have the potential for significant compression or collapse under structural loads and/or when wetted.All foundation and roadway designs for this site should be based on the recommendations of a qualified geotechnical engineer. I suggest requiring the developer to provide a geotechnical investigation that 1)includes a soil testing program of lot specific soil/bedrock borings,2)characterizes soil/bedrock engineering properties,3)provides a basis for mitigation of any potential hazards and 4)provides recommendations for structural design allowances. 3) ISDS.The referral material indicates that ISDS units are proposed for wastewater management on each of the residential lots. Due to likelihood of shallow groundwater on the site,engineered wastewater systems may be required. I suggest basing the ISDS design on site specific percolation tests and groundwater conditions after the building and absorption field envelopes have been located. Due to the potentially high water table, backup leach field sites should be located on I COr • Page 2 January 22,2002 each lot and should be defined in the site plan as areas that must be used as backup leach fields. Additionally, increasing the size of the residential lots may provide the space necessary to build effective ISDS for each lot. In summary,although there are some hazards at this site that could cause concerns with residential construction,standard engineering techniques typically allow construction to proceed. Provided the above comments are addressed at the preliminary plan stage of the planning process,there appear to be no hazards at this site that would preclude the proposed zoning change.CGS would be pleased to review any other pertinent material you may receive for this project,at your request.

As stated in previous letters the projected student impact upon the Johnstown-Milliken School district appears to be minimal, except for transportation, as presented at this time. Currently our elementary schools and middle school are above capacity and our secondary school is nearing its capacity. Our facilities plan indicates that we will have the need to build an additional elementary school within the next two years. As of this date the Towns of Johnstown, Milliken and Berthoud have formally passed a resolution and ordinance describing the land dedication or cash in lieu of land dedication for education. At present,the cash in lieu of land dedication fee is $750. This fee is paid at the time of the issuance of a building permit and is paid directly to the school district. As this exemption directly effects the school district adversely, I would request, as a minimum, that the applicant voluntarily contribute the same fee as all other homebuilders in our communities have done since the inception of the local IGAs. It would also be advisable that a common area/shelter be provided for the pickup and drop-off of students in this development. Sincerely, Jac .

The proposed water supply is from the Little Thompson Water District (District) and a letter of obligation was submitted with the referral materials. A water supply information summary sheet was included and the estimated water demand is 93.8 acre-feet per year. This proposed subdivision includes irrigation of 50 acres. It is noted the District letter does not specifically acknowledge supplying other than domestic water supplies, since the referenced tap size is 3/4 inch diameter. Pursuant to Section 30-28-136(1)(h)(II), the State Engineer's Office offers the opinion, that contingent upon domestic water service being provided by the Little Thompson Water District, the proposed water supply will not cause material injury to existing water rights, the supply is expected to be adequate. This recommendation does not infer an opinion as to the water supply for the proposed 50 acres of irrigation. If you have any questions in this matter, please contact Bill McIntyre of this office.
