HomeMy WebLinkAbout2.0 BOCC Staff Report 03.11.1996• • BOCC 3/11/96 PROJECT INFORMATION AND STAFF COMMENTS REQUEST; Special Use Permit for the operation of a concrete batch plant. APPLICANT; Grant Brothers Construction, L.L.C. LOCATION: A portion of land within Section 7 & Section 8, T6S, R92W of the 6th P.M.; located approximately two (2) miles west of Silt, north of Interstate 70. SITE DATA: 170 Acres WATER; Ditch water used for industrial purposes; bottled water used for drinking purposes. SEWER: Portable Chemical Toilets ACCESS Direct access to I-70 fiontage road (CR 346N) EXISTING ZONING; A/I ADJACENT ZONING:, East/West: A/I North: A/R/RD South: A/R/RD; PUD RELATIONSHIP TO THE COMPREHENSIVE PLAN The subject property is located within District D - Rural Areas/Moderate Environmental Constraints and District F - River Floodplain/Severe Environmental Constraints, as designated by the Garfiled County Comprehensive Plan's Management Districts Map. H. DESCRIPTION OF THE PROPOSAL A. Site Description: This 170 acre tract is located approximately two (2) miles west of Silt on the north side of Interstate 70. Slope across the tract is quite gradual, and generally slopes downward from the Interstate to the Colorado River. Portions of the property are within the designated floodplain of the Colorado River; however, it appears the area proposed for the batch plant is not within the floodplain. The majority of vegetation appears to be pasture grasses and the site survey indicated that portions of the property were being actively grazed. See vicinity map, page B. Adjacent Land Uses: The adjacent land uses appear to be largely agricultural, typically grazing and the raising of hay. C. Proposal: The applicants are currently conducting a gravel mining operation in what is known as the Loesch Pit, permitted under Resolution No. 84-48. This Resolution found that the original operators complied with all conditions of approval as set forth by an earlier Resolution (81-141) for the issuance of a Special Use Permit for the extraction of natural resources and the operation of a concrete batch plant. This application is to amend the original permit to allow the operation of a concrete batch plant at a site approximately 1200 feet east of the site originally approved for the batch plant, shown on the sketch map as 'Stage P.' See sketch map, page " . • • The new batch plant site (shown as Proposed Stage P') will be exactly the same areal size (5.50 acres) as the approved site; however, it will be closer to the actual area of the pit that is currently being mined, therefore, increasing efficiency. The batch plant site would also be the location of the office and may also include related industrial equipment, shops and parking areas. III. MAJOR ISSUES AND CONCERNS A. Operation: Resolution 84-48 approved the special use permit for the proposed operations at the Loesch Pit and found that all conditions of approval specified in earlier resolutions had been complied with. Specifically, Resolution 81-141 instructed the applicants to provide direct access to Interstate 70, without traversing any County road. This provision has been complied with by the construction of the I-70 interchange known as Exit 94 and, further, the use of the interstate frontage road known as CR 346N, which appears to be a state right-of-way, not a county ROW. It must be further noted that these conditions were specified due to the anticipated number of round trips per day from the pit, estimated at the time to be 130 RT. The applicants are currently running an average of three (3) trips per day for gravel and estimate that the batch plant would generate approximately 20 trips per day during the height of the construction season. B. Zoning: The subject property is located within the AA zone district, which does allow, upon issuance of a Special Use Permit, both a plant for fabrication of goods from processed natural resources (batch plant) and extraction and processing (mining operation). Because the Zoning Resolution does not have a provision for modifying or amending a special use permit, the requested permit to move the concrete batch plant must be considered a new permit, to be added to the existing permitted uses. The only essential difference the applicants are requesting is to locate the approved batch plant approximately 1200 feet closer to the actual portion of the pit currently being actively mined. Any approval of the SUP should require compliance with previously approved resolutions as well as any new conditions of approval. C. Permits: The applicants are operating under valid permits issued by the State of Colorado that do allow a concrete batch plant and associated cement silo, as well as a permit for a crushing and screening plant with wet spray bar control equi men and have an additional permit for wastewater discharge. See permits, pages ?�-1 The emission permit for the batch plant sets forth specific terms and conditions in the operation of the plant. Staff recommends that the applicant adhere to said conditions and, if the permit is ever modified to allow additional emissions, then a copy of that revised permit be submitted to the planning department. D. Water Usage: It is difficult to predict the amount of water that would be consumed in the operation of the concrete batch plant, as it would depend on prevailing market conditions and demand. However, the applicants own water shares in the Last Chance Ditch and have converted the water right to industrial and incidental domestic use. It appears that 20.68 acre feet of water, per year, has been decreed to be used in this operation, which staff assumes will be sufficient water to supply all proposed use related to the operation of the pit and batch plant. See water information, pages The applicant has verbally represented that drinking water would be furnished by a bottled water provider and that the washing of trucks will continue to occur at an off- site commercial washing facility. E. Colorado River Floodplain: The 100 -year floodplain of the Colorado River has been mapped and does occur on the applicant's property; however, the floodplain does not occupy the property where the proposed batch plant would be located. See floodplain map and supporting information, page 1.21. The engineering information recommends that any new structure be built at an elevation at least one (1) foot above the adjacent 100 -year flood elevation. --- • • F. Impacts on Adjacent Lands: There will be impacts caused by the generation of dust in the operation of the permitted uses. As discussed earlier, the applicants do have valid permits that specify control measures to be used in limiting the amount of dust generated by the mining and fabricating activities. Staff recommends that the applicants adhere to these provisions and if they are ever modified, then a copy of the amended permit be submitted to the Planning Department. G. Impacts on Animals: The property in question is actively being grazed; however, staff does not know the nature of the permitted grazing. Staff would recommend that if the lands adjacent to the pit or the batch plant will continue to be grazed, then the applicants should take appropriate measures to safeguard the animals, which include some type of adequate fencing. The area where the proposed batch plant would be located is in an open field with very little cover and is probably not a critical area for wildlife. Staff would expect that measures taken to safeguard domestic animals would have positive effects on safeguarding wildlife. If a fence is necessary, staff recommends the applicants construct it to meet Division of Wildlife guidelines. H. Traffic: The permitted amount of truck traffic, in round trips per day, is 130, with the applicants currently operating at a much lower level. As reported earlier, there is an average of three (3) round trips, per day, generated by gravel trucks, and it is anticipated the batch plant will generate an additional 20 round trips during the height of the construction season. The I-70 interchange (Exit 94) was constructed, at least in part, to handle the expected 130 daily round trips and as an earlier condition of approval, the haul trucks are required to use the frontage road (a state highway) to access the interstate. Staff anticipates no impacts to county roadways, but recommends the applicant receive any necessary approvals from the state highway department regarding any new driveways or intersections with the frontage road. Separation of Land Uses: There are residential land uses within a reasonable proximity to the applicants property and the proposed batch plant site. Given the separation of these uses and the location of the Interstate, staff does not expect significant problems to result from the relocation. J. Reclamation Plan: As this request is solely for the relocation of the proposed batch plant, the reclamation plan originally approved for this project would remain in effect. Staff recommends that the applicants conduct their mining and reclamation efforts in strict accordance to the proce res outlined in the earlier, approved SUP application, which is attached on pages .i3 -31 IV. SUGGESTED FINDINGS 1. That proper posting and public notice was provided as required for the hearing before the Board of County Commissioners. 2. That the hearing before the Board of County Commissioners was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that hearing. 3. That the application is in compliance with the Garfield County Zoning Resolution of 1978, as amended. 4. That for the above stated and other reasons, the proposed Special Use Permit is in the best interest of the health, safety, morals, convenience, order, prosperity and welfare of the citizens of Garfield County. V. RECOMMENDATION Staff recommends APPROVAL of the application, subject to the following conditions: 1. That all representations of the applicant, either within the application or stated at the hearing before the Board of County Commissioners, shall be considered conditions MOW 3•-• • • of approval. 2. That the operation of the facility be done in accordance with all federal, state and local regulations governing the operation of this type of facility and that all permits remain updated and in effect at all times. If any permits are modified, then a copy of the modified permit(s) shall be sent to the Planning Department for inclusion in the file. 3. That the applicants receive any necessary driveway/intersection permits from the Colorado Department of Highways, prior to the commencement of batch plant operations. 4. That if the applicants will continue to allow grazing of domestic animals on the property, reasonable care shall be taken to safeguard the animals and any fencing shall be done in adherence to accepted Division of Wildlife guidelines regarding fencing. 5. That all current and future operations of the permitted uses of the property be done in a manner that is consistent with all earlier approvals and conditions of approval regarding the operation of the facilities. Any future modifications or amendments to the permitted uses shall require issuance of an additional Special Use Permit. The issuance of this Special Use Permit only allows the concrete batch plant to be placed as shown on the sketch map, it does not supersede any other requirements or conditions. 6. That only one (1) permitted, Phase P (batch plant/offices/supporting facilities) will be allowed to be in operation at any one time. � / -.�'u u -i �� G rt- � 61.✓ /✓61 �t'�''+ ° 144 (,14X /N r✓' (-i-/-4'2 j r 6� 34/\1' OP 5506 GPC7U5 5500 e 1 III -, � °..0 S,II ,-.G---5.-P^••) II II ,, 17•.+I n ✓ \II Il (,1 N V ALI.E Y 1 1 II 0 CC CC II • ZO 51' •�a'o II /U/ 1'1 It• — (till 5387 Antlers r ^_ 12 -� - rR - 1392 Il r - "— /43,L3-1?-%.

Your property is located on panel 080205 1360B and is classified as being in zone D. Zone D is an area of undetermined, but possible flood hazard. In other words the area is not mapped. Therefore a flood plain has not been adopted by Garfield County for this region. In 1984 a new flood plain was prepared by the U.S. Army Corps of engineers and the CWCB for all of the Colorado River. The new flood plain analysis has not been officially adopted and reviewed. However, in our opinion the best available existing flood plain information is the 1984 maps. We have attached a copy of the 1984 maps covering the area of the Loesch Pit's existing and proposed batch plant sites. From the maps it can be seen that both of the batch plant sights are out of the designated 100 year flood plain. We recommend that the finished floor elevation of any new structures in this area be at an elevation of least 5369 feet which is 1 foot above the adjacent 100 year flood elevation. If you have any questions, please call our Glenwood Springs office at 945-5700. Very truly yours, Zancanella and Associates, Inc. Thomas A. Zancanella, P.E. TAZ/95218 flood .wpf 1 • • 1. .

The operator proposes the planned future use of the property to be a private recreation area with an improved habitat for wildlife. The affected land will be reclaimed by backfilling the perimeter o1 the pit to slopes of 3 to 1 and by creating shallow water areas, or by mining and backfilling to create an :irregular shoreline, and by revegetation of the area to :its natural conditions that will create a desirable habitat for wildlife. The lake to be created will be approximately 143.61± acres. TL will be approximately 4,000 Peet long in an east - west direction and wi I l vary 1.n width north Lo south from 600 feet Lo 2,100 feet:. The shorelines generally will be irregu- lar except in the east and southeast perimeters of the pit. These areas will be relieved by irregularities created by mining or by backfilling so as to present a more natural appearance. Perimeter slopes will be maintained at 3 to 1 or less from five feet above to ten feet below the water level of the lake. One area of 6 to 1 slopes will be created with a sand beach to facilitate swimming and boating if so desired. The tentative selection of a site for the beach area is along the south side near the west end. Separate areas on other parts of the lake shore will have relatively shallow water lo encour- age the growth of reeds and rushes and to create a desirable habitat for water fowl. Location of these shallow water areas a3 - 1 4 - • EXHIBIT E (Cont' d) is not definite at this time; however, ii. is expected that three areas along the east and southeast and northwest sides of the lake are the most likely locations. See Map Exhibit F. As outlined in the Mining Plan, the area will be mined in seven stages. Each stage will last for two to four years, except Stage P which will be :in operation during the entire life of the mine. At the conclusion of each mining stage, a reclamation phase will be commenced. Map Exhibits D-1 and F contain complete details and progression of mining stages and reclamation phases. In salvaging topsoils, reference will be made to the soils map, Exhibit I-1. 1 t is expected that approximately 12 inches of soil will be salvageable. Approximately 8 to 12 inches of topsoil will be redistributed on the areas of the property to be reseeded. The availahle water capacity at that depth will be approximately one inch and is considered suitable for the species recommended. In the area of the affected land, use of mulches and irrigation often creates very severe weed problems. A depth of 8 to 12 inches of top- soil will eliminate the need for mulching and irrigating but will allow development of adapted species. (See Revegetation Program later in this Exhibit E.) The operator will attempt to complete final grading, fertilizing and seeding within one year of the completion of each mining stage. Planting and fertilizing will occur between raid -September and late October whenever possible. EXHIBIT E (Cont'd) If fall planting is impossible and spring planting is an unavoidable necessity, the operator will plant between mid - and late March in each revegetation year. During the balance of the reclamation phase, reclamation progress will be monitored and remedial work will be performed where necessary The operator believes that when the site is reclaimed, conditions for many species of wildlife will be improved. Reclamation Performance Standards. The operator intends to conduct :its mining activities in compliance with the Reclamation Performance Standards of Rule 6. Grading will be performed to create a final topography appropriate to the planned future land use. When backfilling is necessary, the operator will replace overburden and waste materials in the mined area and will insure that the heavy equipment used for this purpose is compacting the earth sufficiently well to achieve good stability. All grading will be done in a manner• to control erosion and to protect areas outside the affected land from slides or other damage. All backfilling and grading will be completed as soon as feasible after the mining process. All refuse will be handled and disposed of in a manner that will control unsightliness and protect the drainage system from pollution. There are no acid-forming or toxic materials involved in this operation. There are no drill or auger holes on the land. Maximum slopes will be within the limits set forth in the Rules and Regulations of the Board and will be capable of being traversed by farm machinery. • • EXHIBIT E (Cont'd) This operation will be carried out by dewatering the sand and gravel deposit and raining under semi -dry conditions. There will be some local disruption to the prevailing hydro-/----r- logic ydro-/logic conditions during the life of the mine. The operator will comply with applicable Colorado water laws and E gul.a,---- tions (as the operator understands them) governing injury to existing water rights in order to minimize any disturbance which might occur Lo the prevailing hydrologic balance of the affected laud and of the surrounding area and to the quality of water in surface and groundwater systems both during and after the mining operation and during reclamation. In addi- tion, the operator expects to comply wi_tli applicable federal and Colorado water quality laws and regulations. There are no dredge facilities nor are there any temporary or large silta- tion structures involved :in this operation. There will be no earth dams. See Exhibit G for details concerning water resources. The mining and reclamation plans take into account the safety and protection of wildlife remaining on the mine site, at the processing sites and along all access roads to the mine Site. Wildlife habitat improvement is a specific part of the reclamation plan. Where it is necessary to remove the topsoil and overburden to reach the mineral deposit, the highest -quality topsoils found on the affected land wi11 be removed in sufficient quantity to implement the reclamation plan. 'These topsoils • EXIILBIT E (Cont'd) will be segregated and protected. If the topsoil is not replaced on areas Lo receive revegetation within a short enough time (not to exceed one growing season) to avoid deterioration of the topsoil, vegetative cover or other means will be employed to preserve the topsoil from wind and water (� erosion, to protect it from any contamination by acid or toxic materials, and to keep it in a useable condition for sustain- ing vegetation when it is redistributed in accordance with the reclamation plan. Topsoil stockpiles will be maintained to minimize erosion and will be located in areas where disturbances by ongoing mining operations will be at a minimum. The top- soils will be handled as little as possible until they are replaced in disturbed areas. The operator will take measures necessary to insure the stability of the replaced topsoil on graded slopes, spreading it: as evenly as possible. Fertilizer and other soil amendments will be used as required in the Reclamation Plan or as the soil tests indicate. .Revegetation- Revegetation will be carried out in such a way as to establish a diverse, effective and long-lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation, soil amendments or v, tha p. 1t'., tv ._ !.t 1 I1t. ! ki 1(111.' i 1'11I,i EXIIIBIT E (Cont' d) to slopes commensurate with such use. Seed will be drilled wherever possible. Where drilling is not possible, the seed will be broadcast. The revegeLation plan provides for the greatest probability of success in plant establishment and vegetative development by considering environmental factors such as seasonal patterns of precipitation, temperatures and wind. Other factors, such as soil texture, fertility, slope stability and the direction in which slopes face, have been considered. A weed control plan is included in the program. Necessary access roads will be constructed through the areas to be planted. The roads will provide access for planting crews and for the supervision and inspection of the reclaimed land. IlevegetaLion Program. The revegetatlon program to be implemented by the operator is detailed below. This plan is excerpted from a report prepared by Mark A. Ileifner of Oikos Environmental Services and is based on his investigation of soils and vegetation on the site (see L' h i i t. 1 and j).

Fertilizers to produce the best growth in the shortest time will be added prior to seeding. 2. Seedbed Preparation. When the soil has been spread and the fertilizer distributed, the surface will be smoothed of large clods and worked until_ moderately fine where the seed • • EX111131'1' E (Cont'd) is to be drilled; the surface will be left fairly rough where it is necessary to broadcast the seed. 3. Seed Mixture. The following mixture will deposit about 31 live seeds per square foot and should be drilled in all areas to be revegetated. The mixture is designed to be drilled at a depth of 1/1 to 1/2 inch; if it is necessary to broadcast the seed, seed rates will be doubled and will be spread on a rough surface and dragged thoroughly after seeding Species Lbs.

This mixture does not require a mulch and, in Tact, on these soils a mulch could be a distinct deterrent to successful revegetation because the mulching action would keep the soils more moist and somewhat cooler that desirable and would induce excessive salt buildup in the soil surfaces. 5. Irrigation, Irrigation is not considered necessary for establishment of the recommended revegetation.. 6. Weed Control.

The operator does not i.ul.end to plant many 1?' • EX1iIBIT E (Cont' d) trees; however, some cottonwoods will be planted in a few selected areas to improve final reclamation conditions. 8. Graz:i.nE, No horse, cattle and sheep grazing will be permitted during the first two or three years because grazing would damage the young plants 9. Native Invaders. A number of species can be antici- pated to invade the area rather heavily in the first five to seven years. Most will :invade along the lake shores. Willow, tamarisk and saltgrass can be expected to invade strongly in the wet and saline areas. Also, cattails and reeds will invade the water areas immediately offshore, thereby providing excellent wildlife habitat and littoral conditions. Sagebrush and rabbit - brush will invade the upland areas where soils are more coarse. Possibly some cottonwood will be found in selected areas, but this is questionable. fax Elder probably will not invade until the vegetation becomes stable and the soils are better developed.
