Don Carroll, Project Administrator. Of S-422, Zeek Properties PUD Final Plan Subject. Rademacher Business Parks The Weld County Public Works Department has reviewed this proposal; the following comments are recommended to be a part of any approval: I_ The applicant needs to rhange and clarify the right street names on all documents that reflect the recorded plat. 2. Lot 10 is being submitted as being a part of the plat. This lot needs to reflect a 20 foot right- of-way dedication for future widening of WCR 9.5. 3. The developer will provide on the plat a 60 foot street right-of-way dedication across portions of Lots 8 and 9, Block 1, for the purpose of a third access point connecting to WCR 9.5. The access point to WCR 9.5 needs to be built at a 90' angle to provide an adequate sight distance in both directions. 4. All lots must access through the internal road system with no direct access to any County roads. 5. The applicant needs to secure a sign -off sheet from the ditch company verifying that there is adequate free board in the Baugh Lateral Ditch, and it will be able to handle any stormwater run-off from the site. 6. On the Off -Site Street Improvements Agreement, the applicant needs to add the item number and description showing the engineering costs that would be required to develop and build this section of WCR 9.5. 7. The applicant needs to place on the mylar two typical cross sections, on reflecting the internal mad system and the other should show WCR 9.5 as an off -site improvement These cross sections should indicate right-of-way widths, driving lanes, shoulder area, curb and gutter or sidewalks (if required), and depth of asphalt and base with adequate drainage ditches on both sides. The cross section also needs to indicate the typical culvert access for drainage. According to Weld County's standard, the minimum culvert size is 15 inrhes with -12 inches of cover. 8. Theapplicant needs to install stop signs at all access points from the industrial paTK to control the intersection. Will the existing house on Lot 10 along with the propane storage area remain as a part of the industrial park? If so, we will have to address the access point on to WCR 9.5 during the upgrading and widening of this stretch of road EXHIBIT 1 76 04/04/97 10:39 971079 TX/EX NO.6900 P.002 • 04/04/97 11:39 FAX 970 352 2888 WELD PUBLIC WORK IJ003 Todd Hodges March 13, 1997 Page 2 9. The Weld County Public Works Department has reviewed the stormwater drainage. All lots are required to retain and release water at the rate not to exceed the quantity of a five-year storm based on an undeveloped site_ The drainage swales need to divert run-off around the site will carry the storm water to the existing historical flow patterns. Lots 1 through 7, Block 1, will all drain to the north and east; these lots are north of Baugh Lateral Ditch_ It will flow to an existing County culvert that crosses under WCR 32 to the historical storm water drainage pattern. The remaining lots within the industrial park will drain to the north and east into the Baugh Lateral Ditch. This will be accomplished through drainage swales and area inlets. cc i Commissioner Harbert S-422 file pian12 971079 04/04/97 10:39 TX/RX NO.6900 P.003 II March 6, 1997 —w DIRECTORS BOULDER COUNTY a Raymond Joyce Lea Williams Ruth Wright IARIMER COUNTY Mike Applegate William H.

Parcel Number 120723002000 Dear Mr. Hodges: The Northern Colorado Water Conservancy District, (NCWCD) acting by and through its Southern Water Supply Project Water Activity Enterprise, has reviewed the above filing for the proposed development plan. The NCWCD owns a 50 -foot permanent easement and an adjacent 40 -foot temporary construction easement until February 13, 1998. The NCWCD's easements are located adjacent to the I-25 Frontage Road from County Road 32 to north and approximately 1000 feet to the south. At that point the easement turns and heads in a southeasterly direction across the Zeek property until it meets with County Road 91. The permanent easement states that the GRANTOR may not "Use the Property for any purpose except agriculture without the prior written consent of GRANTEE; provided, however, the written consent of the GRANTEE will not be unreasonably withheld for the following uses." I have enclosed a copy of the permanent easement deed, which was executed on February 13, 1996 for your review. The NCWCD has had some discussion with Landmark Engineering Ltd., and we would like to meet with them and Zeek Properties Ltd. to discuss plans for the NCWCD's easement. Zeek Properties Ltd. must obtain a License from the NCWCD to place permissible facilities above and below the surface of the ground of the permanent easement. If you should have any additional questions please call me at 970-667-2437. Sincerely, -/4,n im L. Struble Rights -of -Way Agent Enclosure 97079 COLORADO TO: Todd Hodges, W.C. Planning DATE: MarchyS19.97 r FROM: Trevor Jiricek, W.C. Health Department RE: S-422, Zeek Properties, Inc. As indicated in our previous referral dated July 30, 1996, our Department will review and comment on each individual use as it is presented in the Site Plan Review process. However, the submitted application materials indicate that septic systems will serve the proposed structures. The proposed acreage per septic system is adequate. However, the typical operational life of a septic system is 15 to 20 years. After this time period the lots would likely be fully developed. It has been the Department's experience that after development there is not adequate area for replacements systems. Therefore, the Department recommends the following standard: 1) The applicant shall designate an appropriate area on each lot for a replacement septic system. The area should be based on the approximate hydraulic flows considered for the current use as well as any planned expansion. In addition, because it is not yet known what the future uses of the property will entail, we recommend the following standard: 1) The use's of future tenant's, lessee's, operators, etc. may result in wastewaters which are not suitable for disposable in a typical septic system. Any operation which will produce a non -domestic sewage wastewater must submit a plan of disposal to the Weld County Health Department for approval. The plan must be submitted and approved prior to operation at the site. The plan must describe the process which creates the wastewater, the expected composition (analytical data may be necessary) of the wastewater, the proposed method of treatment, and any additional information as determined by the Weld County Health Department.

I or hhcm, 1 kr'rutivc Director Mir hael R. inns Division Director v., ki Cowan 5tnw Ornh y;i,l aryl Dire, for Dear Mr. Hodges: In response to your request and in accordance with Senate Bill 35 (1972) 1 visited this property to review the plat. Landmark Engineering sent on a Preliminary Subsurface Exploration prepared by Earth Engineering Consultants (EEC, August 1995). Also available were a Geotechnical Investigation prepared by Empire Laboratories, Inc. (April 1983), a Preliminary Drainage Report prepared by McCarty Engineering Consultants (August 1984) and a Developmental Report prepared by Rocky Mountain Consultants (no date). Ground moving had begun at the time of my site visit. My comments are listed below. 1) Subsurface drainage. Because of the high groundwater conditions, structures which include subgrade construction should incorporate foundation drains into the building design. More effectively, foundation drains may be incorporated into a site -wide underdrain system. 2) Septic systems. The subdivision will rely on 1SDS. The problems with siting these features arc the a) local high groundwater levels; b) clayey soils; and e) shallow bedrock. Because State regulations demand a minimum 4 -foot separation between the base of the leach field and the groundwater table, engineered septic systems will be required unless an underdrain system is installed to lower the water table. Percolation rates that were obtained when the site was first proposed in the 1980s ranged from 20 to 120 minutes per inch, which shows a high variability and is a flag that subsurface conditions favorable to leach field siting are probably not very laterally extensive. Shallow bedrock at the site has served to trap shallow groundwater and will act similarly with leach field seepage. A leach field may experience premature failure under these conditions, even though initial percolation rates were acceptable. Although the property will be developed conunercially and is not likely to sustain the level of water usage associated with residential development, the developer should propose alternative engineered demos to coµntcracl_such adverse conditions. 1= Fts 2 Post -It Fax Note 7671 Dasre..�`.)

The site is covered by loess that is underlain by bedrock of the transitional member of the Pierre Shale. 'I'M Standard Penetration Tests indicate that the first few feet of soil are composed of stiff silty clay, and this is underlain by 6 to 14 feet of soft silty sand. This evaluation issupported by the Soil Conservation Service, which characterize the onsite Kim and Wiley soils as having low strength. The type of building and its function should be carefully analyzed, since the thickness of the stiff clays (53 ft.) is not enough to support heavily loaded structures. Drilled pier foundations should be considered in these cases. Alternatively, since bedrock is present at shallow depths (5 to 10 ft.), soils could be excavated and replaced with a structural fill that would support spread footings. EEC stated that foundations based on footings would be appropriate for lightly loaded structures. This evaluation may hold for buildings such as warehouses. There was a valid concern raised in the EEC report that dewatering could cause soil shrinkage, and consequently, settlement. The soil moisture contents indicate probable saturated conditions. 1f the moisture content drops, these soils may become subject to shrink -swell behavior that fluctuates with seasonal precipitation. For this reason, piers drilled into bedrock would be the preferred foundation choice, as piers would not be susceptible to soil movement. 3) Drainage. Reportedly, the onsite irrigation ditch will be relocated and lined to prevent seepage. As explained by J.L. Walter, who was on site during my visit, the drainage plan calls for constructing a small detention pond on each lot, with flows to be released at historic rates to the ditch. If this is the intent, the ponds should each be lined, to prevent seepage from pending on the bedrock surface. The drainage diversions to the ditch should be constructed with adequate slope to permit flow, and should be lined with concrete or fabric, rather than relying on natural grass -lined swales, which are easily clogged. In addition, lined diversions will prevent seepage from occurring, which could adversely affect absorption fields. The design of the ponds should be examined by a County engineer to ensure that they are compatible with the overall subdivision plan. In summary, the main problem for development at the site is high groundwater and how it will affect leach field construction. Before I can recommend approval of this subdivision I would like to review how the developer plans to deal with this issue, beyond stating that the fmal design will be up to the lot owner. If lots are developed individually with no overall plan, there can be serious impacts to neighboring structures. Finally, although it may seem expedient to route material through the engineering firm rather than the County, my referral was missing pertinent material and did not include a deadline for review. Please contact me if I can be of further assistance. Celia Gr Geologist Si eerely, eenn 02/25/97 09:42 TX/RX NO.6520 P.002 • 971079 Hello
