Since DIA opened, U.S. 85 through Platteville has incurred much greater use; it is very difficult for us who live in the rural area east of Platteville to get across at Grand/Weld Rd. 32 in a timely way and generally I feel it's a risk almost anytime. If my engine were to conk out suddenly, I would have an ugly accident. Accidents are very common at all the intersections of 85 and Platteville. State highway 66 is at capacity and is also very dangerous. The health and safety of Platteville residents and the quality of life of those who would have to live near the mine are in grave jeapardy if this plan is approved. Of less importance, perhaps, but also of concern is the destruction of the historic landscape near the monument of Old Fort St. Vrain, a Colorado Commemorative Site along the Trappers/Taos/Cherokee trails, the site of Weld County's first government and a place of historic significance for Weld County citizens and northeastern Coloradoans in general. For these reasons, I respectfully ask that the Commissioners deny the special use permit being requested by Platte, Sand, and Gravel.

The applicant has stated that there have been two changes made to the original application: a reduction in size-to 180 acres, and a reduction in years-to 20 years. We feel strongly that these changes do NOT address the majority of our concerns or those of the community at large. First of all, these two changes to the scope of this application are temporary. The applicant, Tom Sharkey, during the Platteville hearing on this matter, stated that at the end of 20 years they will reapply depending upon "market conditions", in other words, with continued growth along the front range, the appplicant's intent is to mine the full 800+ acres for the full 100+ years. Even the Weld County Planning Commission stated last week at the October 2nd, 2001 hearing that these"changes" appear to be a "thinly veiled attempt"to push this application through. Also, the applicant made yet another"eleventh hour" change to the application at the October 2nd Planning Commission hearing. They added another haul route, namely CR 36 to South Highway 85. This was not in their original application. Is the applicant allowed to simply make these changes on the fly? No decent traffic study has been done for this new haul route. Had there been one, the applicant would have known the almost impossibility of making right hand turns onto Southbound Highway 85. Also, CDOT has put in place major regulations around the type of improvement these angled intersections require. We are talking YEARS worth of construction to the roadway. The Planning Commissioners also stated that the current haul route in the application- CR 23 to CR321/2 to CR 21 to CR 66- is not legal as the applicant will have no control over contract trucks (the bulk of the expected truck traffic)which can decide to go any direction they like. The same is true of a haul route headed east on 36 to 85. These same trucks can EASILY make the decision to head west on 36 and take the original haul route which has already been declared illegal. This is a problem! In addition, these changes do NOT address historic and EXHIBIT CAROL Harding Docket#2001-69 ..... .

School bus routes have not been considered and the traffic study submitted for the original haul route raises significant questions about its applicability to the truck numbers which are actually in the application. The Weld County Planning Commission agreed that the"numbers do not add up". All other gravel mines we have observed are located directly on or adjacent to a state highway or interstate highway. To route this incredibly high volume of truck traffic onto so many miles of rural roadway is unsafe, unreasonable and incompatible with the way of life of the existing community. The applicant continues to refer to the residents of this community as"insignificant", doing nothing to openly discuss potential solutions to the many problems we see in tuming this beautiful, historic land into an industrial zone. The Planning Commission's recommendation that the applicant"be a neighbor' has, in our experience, been blatantly disregarded. ?"—" Based on the advice of your Planning Commission, which has now voted once to recommend denial, and once to not approve this application, and the basic facts surrounding this faulty application, we ask that you do not approve this application. We ask that you save the way of life of dozens of Weld County residents who depend upon the surrounding land for their livlihoods. And, we ask that you be a part of saving perhaps the most beautiful and historic sites along the South Platte River, from total excavation and destruction.

C• Director of Public Works/County Enginee O SUBJECT: USR-1306, Platte Sand & Gravel - Additional COLORADO Transportation Issues Comments - Alternate Haul Route COMMENTS: The Public Works Department has retained the services of Felsburg Holt & Ullevig (FHU) to provide technical assistance in reviewing the recently submitted alternate"haul route"traffic study for USR-1306. The alternate haul route under consideration is WCR 36 from WCR 23 easterly to US Highway 85. This alternative is being compared to a"southern haul route,"which is composed of WCR 23 south to WCR 32.5, WCR 32.5 west to WCR 21, and WCR 21 south to State Highway 66. Based on a comparative review of both roadway segments, FHU has recommended selection of the . . WCR 36 route for use by USR-1306. (See the attached letter.) RECOMMENDATION: After review,the Department of Public Works concurs that WCR 36 should be the designated haul route for this USR. CONDITIONS OF APPROVAL: Based on the recommendation noted above, the following should be conditions of approval: 1. An improvements agreement should be completed which ensures WCR 36 is paved prior to commencement of product delivery from the site. The applicant should participate in the costs proportional to the truck traffic (18 kip axles) planned to use the roadway. 2. Included in the agreement noted in No. 1 should be a long term agreement to assist in maintenance of the roadway through the life of the USR. 3. The U. S. Highway 85 Corridor Access Control Plan calls for ultimate intersection improvements at the WCR 36 intersection. The agreement noted in No. 1 should include proportionate participation by the applicant for these improvements if they commence during the life of the USR. 4 EXHIBIT I-1-, Use#13o6 USR-1306 October 9, 2001 Page 2 4. As an interim measure,appropriate improvements approved by CDOT should be made to the intersection of WCR 36 and US Highway 85. Included in the improvements should be interim turning radii improvements and lengthening or construction of all US Highway 85 intersection auxiliary lanes. 5. All traffic related to USR 1306 shall be required to use the WCR 36 haul route.

P.E. Public Works Director Weld County P.O. Box 758 Greeley, Colorado 80632-0758 RE: Platte Sand and Gravel Proposal Haul Route Analysis FHU Project 01-220 Dear Mr. Hempen: As requested.we have conducted a comparative analysis of the two haul routes being considered for the Platte Sand and Gravel operation located at the intersection of County Road 36 and County Road 23. One of the truck haul route alternatives would make use of County Road 23, County Road 32.50, and County Road 21 to SH 66. The other haul route alternative would make use County Road 36 to US 85. Relative to the County Roads. either one of these routes would be viable options provided appropriate improvements are constructed. However, one of the routes does offer advantages over the other. Table 1 was prepared to illustrate key comparative measures. The following is a summarization of Table 1 items. • The East Route would involves 57% less County road mileage than the South Route. • In considering travel along the County Roads, SH 66, and along US 85, the East Route would result in fewer vehicle miles of truck travel than the South Route. This is due to the location of the market. Most of the truck traffic generated by the facility will be oriented to/from Denver, but there will be a relatively strong secondary market oriented to/from the Greeley area north of the site. Additionally, a relatively small portion of their market will be located to the area west of the facility. As such, the South Route would tend to force more out-of-direction travel for a larger market segment than the East Route, thus necessitating more truck travel within the localized area. .303.721.1410 fax 303.721.0832 fbudfhueng.com Greenwood Corporate Plaza 7951 E.Maplewood Ave.Ste. 200 Greenwood Village,CO 80111 0CT 09 '01 13:37 FR FHU 303 721 0832 TO 19703046497 P.03/05 October 9, 2001 Mr. Frank Hempen,Jr., P.E. Page 2 • Additional truck trips passing by the Platteville Elementary School has been raised as an issue. While either route would add traffic onto SH 66 at this location, this potential is greater with the South Route than the East Route since the South Route would direct trucks directly onto SH 66. • The number of residences along the two routes was considered in Table 1 as well. As shown, 14 residences were counted along the South Route as compared to a total of 8 residences along the East Route. • One of the key differences between the two alternatives is the state highway that the haul route would make use of_ The South Route Intersects with State Highway 66 whereas the East Route intersects with US 85. Based on historic accident rate data maintained by COOT, the segment of US 85 where the East Route intersects has a much lower accident rate than the SH 66 segment where the South Route intersects. In general, US 85 is better designed for the increased truck traffic given its four through- lanes and its acceleration/deceleration lanes at most of the cross-streets and driveways. SH 66 has very few cross-streets or intersections that are accompanied by acceleration or deceleration lanes. The South Route would require haul truck use of SH 66, whereas the East Route would require use of US 85. • The ability to incorporate acceleration and deceleration lane improvements at the state highway intersections would also tend to favor the East Route. The South Route intersection with SH 66 (County Road 21) should be widened to incorporate a center left turn lane at a minimum, and a westbound acceleration lane may also be appropriate given the fully loaded trucks that would make use of it. However, field observation suggests that the right-of-way along SH 66 in that area may be too narrow to properly accommodate such improvements. At the US 85 intersection of the East Route (County Road 36), there is more than enough right-of-way for needed acceleration and deceleration lanes. In fact, some of these auxiliary lanes already exist, although they would need to be improved in light of increased truck traffic_ • Heavily loaded trucks turning left onto a busy roadway can sometimes be problematic. The potential for left turns onto SH 66 at the South Route intersection would be greater than the potential for left tums onto US 85 at the East Route intersection given the market area locations. A review of the US 85 Access Control Plan was also conducted relative to the East Route.The plan indicates that the intersection of County Road 36 will continue to be a full-movement unsignalized intersection. The US 85 Access Control Plan also shows the realignment of County Road 36 at its intersection with US 85 to alleviate the skew that currently exists at this intersection. The County may want to consider having this applicant participate in this ultimate improvement should the East Route be the chosen alternative. 0CT 09 '01 13:39 FR FHU 303 721 0832 TO 19703046497 P.04/05 October 9, 2001 Mr. Frank Hempen, Jr., P.E.

It should also be noted that a portion of the South Route (County Road 32.50) is proposed to be an on-street bicycle facility per the most recent draft report of the Weld County Roadway Classification Study. It may be advantageous to minimize the level of truck traffic along an on- street bicycle roadway facility. Based on the ensuing analysis, the East Route would be more appropriate than the South Route. In general, the East Route delivers the plant's truck traffic to a roadway facility better designed to accommodate it (US 85)with less impact on the surrounding area. IMPROVEMENTS Regardless of which route Is selected, roadway improvements will be necessary. Needed improvements are summarized as follows: South Route • Turning radius increases at intersections such that turning trucks do not"swing wide" into the opposing lane of traffic upon turning. • Paving of County Road 23.

Page 4 • Maintaining County Road 32.30 as a collector road which should include 12-foot lanes and 4-foot shoulders, and maintaining County Roads 21 and 23 as local roads which also includes 12-foot lanes and 4-foot shoulders. • Analyzing of the pavement section along County Road 32.50 and County Road 21 to ensure that these roadways can endure the additional loading. Pending the results of this analysis, pavement overlays may be needed. • Acceleration/deceleration lane additions at the SH 66/County Road 21 intersection. At a minimum, an eastbound left turn deceleration lane for the short-term time frame. Over the long-term, a westbound right turn deceleration lane, a westbound right turn acceleration lane and a southbound right turn lane should be constructed. The long-term improvements along SH 66 may require additional right-of-way. East Route • Potential paving of County Road 36 and maintaining a local road cross-section which should include 12-foot lanes and 4-foot shoulders. • Acceleration/deceleration lane additions at the US 85/County Road 36 intersection. At a minimum, a northbound left turn deceleration lane, a southbound right turn deceleration lane, and a southbound right turn acceleration lane. Lengths of these lanes should meet COOT criteria. It would also be desirable to realign County Road 36 at US 85 per the Access Control Plan. Barring this, a large right turn radius should be provided for the eastbound to southbound movement at this intersection. • It may be appropriate to remove the stop signs along the County Road 36 approaches to County Road 25 and post them along the north and south approaches as County road 36 traffic increases. This should provide some insight relative to the traffic engineering pros and cons of the two routes. Please feel free to call if you would Ilke to discuss this issues any further.

Table 1. -Population data for the northern Colorado Front Range. 10 ABSTRACT Regional growth,transportation, and land use planning all will be affected by the ability of the aggregates industry to meet future demand for high quality aggregate resources. Increased environmental awareness,public opposition, and stricter zoning regulations have made it more difficult to obtain permits to develop new aggregate mines or expand existing operations in urban areas such as the Colorado Front Range. Local demand for aggregates in the short term is ex- pected to continue at reasonably high levels due to the projected population growth and associ- ated demand for infrastructure improvements to accommodate such growth. Although the Colorado Front Range has an abundance of potential aggregate resources, recoverable resources are coming from greater distances as local resources are becoming inacces- sible for extraction. Available resources are becoming more difficult to recover and more expen- sive to produce due to longer transportation distances,poorer quality of locally available sources, more involved permitting requirements, and the encroachment of other land uses on undeveloped potential resource. The study indicates that the amount of aggregates being permitted has steadily decreased over time. The Denver metropolitan area has been producing more aggregates than it is permit- ting since 1991, and the Fort Collins-Greeley area is currently permitting about what it is produc- ing. If this trend continues,aggregate operators may be forced to move to resource areas even farther away from local markets,resulting in even higher transportation costs. Increased costs for these aggregates would be passed along to the State or counties as higher construction bids, to the contractor as higher supply costs, and ultimately to the consumer in the form of higher taxes or user fees.

(1)After July 1, 1973, no board of county commissioners, governing body of any city and county, city, or town, or other governmental authority which has control over zoning shall, by zoning, rezoning, granting a variance, or other official action or inaction, permit the use of any area known to contain a commercial mineral deposit in a manner which would interfere with the present or future extraction of such deposit by an extractor. (2) After adoption of a master plan for extraction for an area under its jurisdiction, no board of county commissioners, governing body of any city and county, city, or town, or other governmental authority which has control over zoning shall, by zoning, rezoning, granting a variance, or other official action or inaction, permit the use of any I area containing a commercial mineral deposit in a manner which would interfere with the present or future extraction of such deposit by an extractor. (3)Nothing in this section shall be construed to prohibit a board of county commissioners, a governing body of any city and county, city, or town, or any other governmental authority which has control over zoning from zoning or rezoning land to permit a certain use, if said use does not permit erection of permanent structures upon, or otherwise permanently preclude the extraction of commercial mineral deposits by an extractor from, land subject to said use. (4)Nothing in this section shall be construed to prohibit a board of county commissioners, a governing body of any city and county, city, or town, or other governmental authority which has control over zoning from zoning for agricultural use, only, land not otherwise zoned on July 1, 1973. (5)Nothing in this section shall be construed to prohibit a use of zoned land permissible under the zoning governing such land on July I, 1973. (6)Nothing in this section shall be construed to prohibit a board of county commissioners, a governing body of any city and county, city, or town, or any other governmental authority from acquiring property known to contain a commercial mineral deposit and using said property for a public purpose; except that such use shall not permit erection of permanent structures which would preclude permanently the extraction of commercial mineral deposits. Avast 1T, 1801 Palle Sand and Gravel, LLC P.O. Box 180 Utfleton,CO 80160 Subject: Consultation Aggregate►k Development Neer Platteville,Colorado Job No. CS-10,668 Gent amen: In January 2000,we visited the subject site to observe the drilling ofsixteen 1161• • • •nth• st• eva ate the thickness of the eagjnataavehinhlin in L: . , , . . • �►Yi_ pre• red by Terracon • , : - .

SITE CONDITIONS The 1,8003 acre property is mainly contained within Sections 26 and 35 T.4.N. and Section 2,T.3.N.,Range 67 West•The site is about one mile west of U.S.Highway 86 between(Merest and Platteville.Figure 1 contains a map showing the vicinity of the site. For the most part, the site is relatively flat lying. The South Platte River meanders through the western and northern portion of the property.Wildcat Mound, a predominate hill feature,occurs in the northern portion of the property,north of the South Platte River.Figure 2 contains a section of U.S.G.S.map showing the river and Wildcat Mound. SUBSURFACE CONDITIONS During our visit, a total of sixteen 16 exoleratgpt bort wars excavated using a small commercial size editiontfrill rig using 12 and 16-inch diameter bits. We logged conditions found In each test hole. Figure 2 shows the general location of test holes with Figs. 3 through 6 graphically presenting the conditions found. smar. irs:lalt`nQunlorea i"!'el; featnf.silt or glaY-lagia saAdv clay underlain by nand. aravil and rnhhla The aggregates are underlain by clay or bedrock at varying depths.In the southern portion of the site,the aggregates appear to extend to depths In excess of 36 feet.Moving northerly,the clay or bedrock appears to occur at a depth of around 26 feet and at more shallow depths In Isolated places.

Because of the*Ming method, the more fine grain portion of the aggregate layer was obtained.Table A sirnmerlau the gradation of the"In- Mime"marble obtained. AOMEOATE QUALITY/RESERVE table A shows theoretical gradations for coarse and fire aggregates If the samples obtained were split on Number 4 and Number 8 screens Etter material larger than 1-1/2 Inches in diameter Is removed. If the coarse aggregate Is split at the Number 4 screen, meaning there Is no materiel smaller than a Number 4 size, the aggregate would theoretically be suitable for use as Number 57 size concrete aggregate.In order to produce tine concrete aggregate(concrete sand),the material could be split on either the Number 4 or Number 8 screens, meaning ell of the material is smaller than a Number S or a Number 4 size. If the aggregate were split on the Number 4 screen, some blending may be required where as if the fine aggregate is split on the Number 8,It theoretically meets the requirements for fine concrete aggregate. Our scope did not include running physical property testing for quality on the aggregate. However, Terracon performed physical property testing on aggregates from a site located near the subject property. The results of Terracon's work Indicates the aggregates to be of a quality suitable for use as concrete aggregate as well as base course or other structural material.

Below is a summary of the soil limitations that could be encountered if this land is developed: For Septic Systems: The Altvan loam 0%to 1% slopes, and Aquolls and Aquents gravelly susbstratum have severe limitations because of slow percolation. The Colby loam 3% to 5% slopes, Haverson loam 0% to 1% slopes, Kim loam 1% to 3% slopes, Kim loam 5% to 9% slopes, Weld loam 1% to 3%slopes and Wiley-Colby complex 1%to 3% slopes have moderate limitations because of slow percolation. The Altvan loam 0% to 3% slopes, Bankard sandy loam 0% to 3% slopes, Cascajo gravelly sandy loam 5% to 20% slopes, Dacono clay loam 0%to 1% slopes have severe limitations because of poor filter materials. The Aquolls and Aquents gravelly susbstratum have severe limitations because of flooding and wetness. The Haverson loam 0%to 1% slopes have moderate limitations because of flooding. The Nelson fine sandy loam 3% to 9% slopes and Tassel fine sandy loam 5% to 20%slopes have severe limitations because of shallow depth to bedrock. For Small Commercial Buildings: The Aquolls and Aquents gravelly susbstratum have severe limitations because of flooding and wetness. The Bankard sandy loam 0%to 3% slopes and the Haverson loam 0%to 1% slopes have severe limitations because of flooding. The Cascajo gravelly sandy loam 5% to 20% slopes, and the Tassel fine sandy loam 5% to 20% slopes have severe limitations because of potentially steep slopes. The Colby loam 3%to 5% slopes, Kim loam 5%to 9% slopes, and the Nelson fine sandy loam 3% to 9% slopes have moderate limitations because of potentially steep slopes. The Weld loam 1%to 3% slopes and Wiley-Colby complex 1%to 3% slopes have moderate limitations because of the shrink-swell potential of these soils.

Additional information can be found in the publication 'Soil Survey of Weld County, Colorado, Southern Portion' . None of the soils found on this parcel wouldbe_classified.-as-.'prime.. farmland' . Vegetation over the area includes irrigated cropland, irrigated pasture and hayland, native pasture (rangeland) and riparian areas. The irrigated fields are used to grow corn and small grains . These fields are mainly on the upland areas towards the north end of the property. That area between the Western Mutual Ditch and the oil well road in the bottom is primarily rangeland. Most of this area is classified as a Salt Meadow Range Site . Switchgras's, alkali sacaton, tall wheatgrass and tall fescue dominate the site, with production ranging from 2, 000 to 3 , 000 pounds per acre per year. Some of the lower areas have been leveled and planted to a cool season pasture mix (brome and orchard grass) . Some native grasses are starting to invade these areas. Alfalfa has been seeded into some areas but is generally short lived due to the high water table . Production will probably range form 1 . 5 to 3 . 5 tons per acre per year. The riparian areas follow the South Platte River channel and vary from grasses to a mixture of trees and shrubs . There are other small 'wetlands ' scattered throughout the property, as evidenced by the vegetation. I would recommend contacting the the Army Corp. of Engineers regarding the mitigation aspects of destroying these wetlands .

The revised information is a reduction from the original application and therefore is not a substantial change. The primary revision in the application is a reduction of the main mining area to 180 acres and a reduction of the requested time for the permit to 20 years. Additionally, this submittal includes the following exhibits to supplement the record: 1. Mined Land Reclamation Board (MLRB)permit for the S&H mine 2. Western Mutual Ditch Company Water Agreement 3. Western Mutual Ditch Company Easement Agreement 4. Western Mutual Ditch Company Crossing Agreement 5. Traffic Impact.Study— 6. Draft Road Improvements Agreement 7. Xcel Energy Agreement 8.

The City has determined that since you made financial commitments based upon information given to you in November of 1998, that the need for a special use permit, as required by the recently adopted City of Lakewood Zoning Ordinance, will not be necessary. The property at 1300 Harlan Street is zoned Industrial (IN) and cement batch plants were an allowed use in November of 1998.The City hereby grants you permission to place and operate a cement batch plant from your property at 1300 Harlan Street. The City will require a plan showing the location of the proposed plant, traffic circulation and all proposed improvements. A minimum 20 foot setback is required from that portion of the property that is adjacent to residential property. Changes to your layout may be required once the City has had an opportunity to review the plan. The City strongly encourages the installation of a 6 foot privacy fence along the residential area to screen them from the plant operations. Any retaining walls to be constructed must be engineered and they require a building permit if they are over 30 inches in height. The layout and design of the wash area should be reviewed and approved by the City. Please contact Alan Searcy at 303-987-7579 for further information. When we met, we discussed your plans to possibly build a shop for servicing the trucks. It will be necessary to provide a site plan for that construction and to meet the requirements of the City for land development. This basically means that some improvements along the front of the property (landscaping, improved fencing) may need to be installed in order for the City to allow the building. I have enclosed a copy of the Industrial zoning requirements as well as a copy of site development requirements (Article 15). Please refer to the performance standards in the zoning information to determine what improvements might be needed with the construction of the building. It will be necessary to go throueh the City's preplanning process for the building construction. This process will analyze your request and determine any necessary improvements. I have included a pre-planning application for your use. 1300 Harlan St. February 9, 1999 Page 2 I have asked the City's Economic Development section to contact you to provide additional information concerning the possible future development of your property. Please feel free to call me at 303-987-7982 should you have any questions or concerns regarding this information.

The wall must be removed, the slope cut back to a 3:1 or less grade and the exposed soil seeded, mulched and tackified with a city approved seed mix. This work must be completed within 30 days of the receipt of this letter. To initiate construction of an approved retaining wall over 30 inches in height, an engineered plan must be submitted to Gary Kranse (303) 987-7982 for review by City staff. Gary can assist you through the approval and permitting process. The original design submittal was not acceptable due to incomplete information such as no supporting calculations. 2) An Article 15 Site Plan for the property has not been submitted. It is required prior to City staff approving any further site improvements or issuance of any more construction and/or building permits for this property. The Article 15 Site Plan must be submitted to Gary Kranse who will assist you through the plan approval process. R:AWEST\LINNEMAN.WPD 3) The following are Clean Water Act Violations on the property that must be corrected within 30 days of the receipt of this letter: A) A designated truck and equipment wash out area with a City staff approved lining material must be established. The basin must be sized to adequately meet the needs of the activity taking place on the property. B) An industrial permit must be obtained from the Water Quality Control Division of the Colorado Department of Public Health and Environment (C.D.P.H.E.) for the potential storm water and process water discharges from this site. John Kubic, with the C.D.P.H.E. is the City's contact. He can be reached at (303) 692-3605. C) A City staff approved vehicle tracking control must be established at the exit from this site. Mud tracked onto Harlan Street from vehicles leaving this site must be completely removed from the street immediately after it is deposited. Preferably no mud tracking should occur on City streets. . Alan Searcy at (303) 987-7579 is available to answer questions pertaining to the Clean Water Act violations. Failure to comply with any or all of this letter's requirements within the stipulated time frames '� may result in the City of Lakewood initiating legal action against the property owner and/or responsible parties.

It is my understanding that you are the owner of the property and can assist me with my concerns. I inspected this property because of a complaint I received concerning the dumping of dirt, mud and concrete on the street in front of this location. The inspection revealed that trucks from the business are dragging mud and dirt out onto the street. This lot is not paved and the situation gets worse in bad weather. In addition, trucks occasionally spill concrete on the street. Title 9.80.150(F) of the Lakewood Municipal Code states, in part, that the scattering of debris or allowing debris or other waste materials on any public place in the city is a nuisance and is prohibited. The dumping of dirt and concrete must discontinue. A possible solution to the dirtimud problem would be to improve the parking surface of this lot with asphalt or concrete. In order to avoid enforcement action, please discontinue dragging dirt, mud and/or concrete out onto the street and keep the street clean by September 1, 2000. Enforcement action includes a summons into Municipal and/or District Court. Your cooperation in this matter is appreciated. Please call me at (303) 987-7564 if you have any questions.

As you know, Central Ready Mix has built a number of structures on the property without permits. They include: 1. Prefab building , 2. Structure built around the batch plant tower 3. Washout pit Building these structures is in violation of 17-15-1(2) of the Lakewood Zoning Ordinance. If Central Ready mix would comply with Article 15 regulations, this would alleviate many concerns regarding screening, landscaping and surface issues. In addition, Code Enforcement has received complaints about traffic, noise, dust and dirt. This operation could be considered a general nuisance, 9.80.150 and 9.80.150(E).

Staff is currently reviewing the building plan and the retaining wall plan. The site plan as submitted is not in an acceptable form for review. A pre-planing application and review, a formal site plan application, a site plan review fee and a final site plan that is in conformance with the requirements of the City's Article 15 Site Development Standards must be provided. This site plan submittal must include a fmal site plan, a final landscape plan and architectural building elevations. Please note that until such time as a formal application and site plan have been submitted for review and approved by the City of Lakewood, the City cannot and will not approve either the retaining wall plans or the building plans. Additional submittals to be included with the final site plan are a grading and erosion control plan. Further, a drainage study may need to be submitted and on site storm water detention and water quality capture may need to be provided if there is disturbance of more than one acre of ground. You will also need to address the issue of the runoff of the water quality as it relates to the washout of vehicles and material from the batch plant. Staff is very concerned regarding both the building plan and the retaining wall submittal. Neither of these structures meets the City requirements for aesthetics or design. A simple metal building and a 12-foot concrete retaining wall will not be acceptable to the City. I encourage you to make cognizant and credible revisions to these plans that address the issue of aesthetics before the final site plan is submitted. I have also recently been contacted by the Jefferson County Health Department regarding this property. They have indicated that you plan to pave and rock the site in the near future. Any improvement to the site, including paving, must done in conformance with the City's Article 15, a Letter to Brent Schieffer March 28,2001 Page 2 of 2 Site Development Ordinance. It is very likely that more than an acre of ground will be disturbed with the paving, thus requiring a final drainage study and the provision of on site storm water detention and water quality capture. I am including a pre-planning application. A formal site plan submittal cannot be processed until such time as a pre-planning submittal has been received by the City. Please address all of the improvements that you desire to make to the property and the City will provide to you written comments concerning the appropriate process and City requirements needed in order for you to make those improvements. I encourage you to complete the pre-planning application as soon as possible in order to help facilitate the completion of any future formal site plan request. Please feel free to contact me at 303-987-7982 should you have any questions or concerns.

Linneman 3928 Dudley Street Wheat Ridge, Colorado 80033 Brent Schieffer Central Ready Mix c/o 2051 West College Avenue Englewood, Colorado 80110 Re: Code Violations at 1300 Harlan Street Dear Ms. Linneman and Mr. Schieffer: Our law firm represents the City of Lakewood. It has been brought to my attention that numerous Code violations exist on the property at 1300 Harlan Street. More importantly, there have apparently been a number of structures constructed on the property without obtaining a permit from the City of Lakewood. In at least one instance, a City of Lakewood inspector issued a red tag and ordered that the work on the structure be stopped. In defiance of that order, the structure was completed anyway. Additionally, it is my understanding there has been ongoing, numerous conversations and correspondence between the City of Lakewood staff and the staff at Central Ready Mix. Nevertheless, the property at Central Ready Mix has continued to be in violation of Lakewood's Code and continues to be so today. Besides violations relating to construction of structures without a permit, there is an ongoing problem of pollutants leaving the property at 1300 Harlan Street and entering the municipal stormsewer. Additionally, there is junk and debris obstructing the floodplain. Attached to this letter is a draft Complaint which the City of Lakewood will file in Jefferson County District Court on April 16, 2001, if you have not made contact with and met with Brian Nielsen, the City of Lakewood Environmental Manager, by April 11, 2001 (Telephone: 303-987-7192). Please note that this Complaint, besides seeking an injunction to enjoin the property owner and property tenant at 1300 Harlan Street from continuing to violate Lakewood Code, seeks attorneys' fees and costs from both parties. RECEIVED JUN 032001 PFK\G53C•374661 u2 Kathleen L. Linneman Brent Schieffer March 30, 2001 Page 2 If you have any questions, please do not hesitate to call Brian Nielsen at the number listed above or myself at the number listed above.

They are: Violations in the Flood Plain Most of the debris has been removed from the flood plain. However, the junk vehicles and junk trailers remain. In addition, a mobile home remains in the flood plain. Mr. Schaeffer agreed to remove the remainder of these violations within one week. Article 15 Violation No formal application or application fee has been submitted to the City to process a site plan. Mr. Schieffer's attorney, Frederick Ginsburg, told us that he"Will do whatever it takes and give you everything you need by the end of this week." Please call me at extension 7564 if you have any questions. Alternative formats of this document available upon request City of Lakewood MEMORANDUM TO: Peter Nadel, Deputy City Attorney Paul Kennebeck, Deputy City Attorney FROM: Brian Nielsen, City Environmental Manager Department of Public Works DATE May 2, 2001 SUBJECT: Results of Concrete Plant Inspection At approximately 10:15 a.m.Tuesday, April 24, 2001, the following Lakewood employees conducted a site inspection of Central Ready Mix facility at 1300 Harlan Street: • Brian Nielsen, City Environmental Manager • Jon Holmes, Code Enforcement Officer III • Harold Willman, Building Inspector II • Lois Engbretson, Lead Code Enforcement Officer III • Gary Kranse, Planner II • Alan Searcy, Stormwater Quality Coordinator • Mike Gautier, Building Inspector I • Dan Nickle, Building Code Administrator • John Anderson, Construction Coordinator • Charles Parrish, West Metro Fire Protection District • John Jankousky, representing Central Ready Mix • Barbara Orr, representing Metro Waste Water District • Bruce Rabe, representing Regional Transportation District • Brent Schieffer, representing Central Ready Mix • Robert Deckins, representing Central Ready Mix In order to consolidate comments and concerns from the aforementioned individuals, the inspection process was divided into two groups. Those individuals concerned with building and permit issues were in one group and the second group was comprised of individuals concerned with environmental compliance matters. The following concerns by grouping were documented at that time: BUILDING AND PERMIT CONCERNS • Due to the severity of numerous electrical violations a Correction Notice was issued by Harold Willman, City Building Inspector at the time of the site inspection (April 24, 2001) The Correction Notice gives the property owners/ operators 14 days to correct identified problems, otherwise the electrical power to the property will be shut off. • The owners/operators of the facility need to complete a pre-planning application. A formal site plan submittal cannot be processed until such time as a pre- planning submittal has been received by the city. All the improvements that are planned for the property need to be included in the application. The site plan that was submitted is not acceptable. A pre-planning application and review, a formal site plan application, a site plan review fee and a final site plan that is in conformance with the requirements of the City's Article 15 Site Development Standards must be provided. • Obtain a permit to complete work that was started under Permit#79106, for the Control Room construction activities. Include drawings for the building "Tie Downs" since the foundation shown on Permit #79106 was not installed. • Obtain a permit to remove the enclosure structure north of the hopper/separator. Submit plans and obtain a permit for the re-construction of this structure if it is decided to re-enclose the building with a new structure. • Submit plans and obtain a permit for the holding/settling ponds. • Any work not done by the owner or a salaried employee, is to be completed by a contractor licensed in the City of Lakewood. This includes work done by anyone under "owner" permits. • Most of the debris has been removed from the flood plain, however the junk vehicles and junk trailers are still on site. In addition, a mobile home is in the flood plain. ENVIRONMENTAL CONCERNS • The truck wash out pit located on the northeast section of the property needs to be properly closed and future truck wash out operations need to be conducted at the soon-to-be constructed wash out building. The new truck wash out building will be designed to comply with all storm and sewer management best engineering practices. • Apparently, the concrete plant has a current minor source permit with the state for fugitive dust particulates emanating from the hopper/separator. The City requests documentation that indicates that the permit is current and a commitment that all future operations at the plant will never exceed the limits of the permit. • All truck washing activities including acid washing will occur at the soon-to-be constructed truck wash out area. • All excess concrete from returning trucks will be deposited in one location on the property and all surface water from this location will drain to a central collection point. • Until the new truck wash out building is constructed, contain all surface drainage in a temporary sump along the southeast corner of the property. The drainage must be tested for PH, at a minimum, prior to release off site. If PH is 9.0 or greater, the waste must be properly disposed of in accordance with federal and state regulations. • The 4000 gallon above ground storage tank needs a Spill Prevention Control and Countermeasure Plan. The plan needs to be certified by an engineer and the recommendations for complying with the requirements of the plan need to be implemented by August of this year. • All chemical storage containers, to include drums, need to be properly stored according to the 1997 Uniform Fire Code. • Assist City staff with locating storm water conveyances to Dry Gulch and plug if requested. • Eliminate tracking concrete materials along Harlan Street. • Prepare a sampling and work plan to test for contamination on RTD's property. A representative of RTD must approve the sampling and work plan. • The sand/oil interceptor inside the building is full and appears to be plugged. The interceptor needs to be pumped out and the resultant liquids and solids need to be properly disposed of. If the interceptor is to be used in the future, it needs to be routinely pumped out and maintained prior to releasing flows to the sanitary sewer system. Alternatively, if exterior wash operations could be relocated to the new truck wash out area, the use of the interceptor could be avoided along with the need to discharge concrete by-products into the system without prior notice or a permit. This memorandum has not been distributed to personnel representing Central Ready Mix. Please advise as to how and when to communicate our above listed findings and concerns to personnel representing Central Ready Mix. If you need further clarification on this matter, please telephone my office at (303) 987- 7192.

LAKEWOOD.ORG July 12, 2001 Mr. Brent Schieffer Central Ready Mix, LLC P.O. Box 1268 Littleton, Colorado 80160 RE: 1300 Harlan Site Plan Case # SP-01-027 Dear Mr. Schieffer, The City has reviewed the site plan for the site located at 1300 Harlan Street. Staff offers the following comments and concerns regarding the submitted plans. 1. Please add the necessary site plan notes to the plan. I have attached a copy to the plan set. 2. Please add an impervious data sheet to the plan set. A copy has been attached to the plans. 3. Please add the following note regarding the storage of materials within the flood plain. "The storage of inoperable motor vehicles, equipment, trailers, or any material within the designated flood plain is prohibited. No structure of any type shall be permitted within the designated flood way. Parking of operable motor vehicles within the flood plain and flood way is permissible." 4. There are a number of specific details that need to be added to the plan set. These include: a. fencing details, need a detail for each type of fence b. retaining walls c. storage bins d. washout pit e. washout capture area f. concrete swales g. any site specific improvement 5. Architectural elevations of the storage facility building need to be provided. SP-01-027 1300 Harlan Street July 12, 2001 Page 2 of 3 6. There are several sanitary sewer easements that need to be shown on the plan. I have included a plan showing those easements for your use. It is possible that there is the need to dedicate additional easements for the existing sanitary sewer that is in the Gray Street alignment. Please review the existing recorded easements and determine if additional easement dedication is needed. • 7. The washout capture area and the proposed detention pond are both within the existing sanitary sewer easement. The design of the washout capture area needs to be provided so that any conflicts with the sanitary sewer can be reviewed. The detention pond design needs to address the existing sewer line as well as the existing manhole that falls within the pond. 8. Please clearly differentiate between the property lines and the development area. Lease lines do not need to be shown. 9. Please delineate the flood way from the flood plain. 10. It is unclear as to how many fences are being proposed along the southern property line. The proposed six-foot concrete panels along the south boundary are not permitted since they are located within the flood way. No structure is permitted within the flood way. This also implies that the existing chain link fence that is within the flood way cannot be relocated or reconstructed. The City cannot issue a permit for any alteration to the existing fence within • the flood way. The only option for the fencing is to allow it to remain in its current state, or to completely remove it. 11. The City would prefer that the landscaping along the northern property line, east of Gray Street and the landscaping along the east property line be placed outside of the six foot privacy fence to provide additional buffer to the residential area and the park. This would require setting the fence back from the property line approximately five to eight feet. 12. Each tree and shrub needs to be specifically identified on the landscape plan so that it is clear as to the number, type, size and location of each planting. 13. Along the west and east boundary lines, there are existing overhead power lines. As such, the species of trees installed in these areas needs to be compatible with the overhead lines. I have included a copy of acceptable trees for planting in such areas. 14. Please do not use slats in any of the fence installations. 15. Please consider changing the existing chain link fencing to vinyl coated chain link. 16. The site plan and the landscape plan do not anticipate any additional buildings on the site nor does either plan identify any additional paving. Please review and identify if future buildings are contemplated or if any paving is going to occur. 17. Please identify all adjacent rights-of-way widths. **Alternative formats of this document available upon request" SP-01-027 1300 Harlan Street July 12,2001 Page 3 of 3 18. Please show all topography within 50 feet of the property lines. 19. Please see the redlined plan comments. Once the corrections have been made and the concerns addressed, please resubmit five copies of the revised site plan package (including landscaping) as well as all of the redlined plans. Please note that this review does not include engineering comments. A separate letter from the engineering division will be sent addressing those comments. I have also included a letter from the Two Creeks Neighborhood Association. Please review this letter and respond to their concerns. In particular they would like a meeting to discuss the proposed site improvements. I can facilitate that meeting should you so desire. Please feel free to contact me at 303-987-7982 should you have any questions or concerns.
