The applicant is requesting to amend Section 7-840 as follows: Section 7-840 E. Impacts to County Road System; Items 3 and 4; change language to insurance minimums based on actual access to and use of County Roads and; specific requirements to improve adjacent roads and monitoring by the County. Section 7-840 H. Reclamation/Enforcement; Items 1 and 2, expand language to slope requirements in (a) wetland areas and (b) dryland areas and expand language for revegetation in (a) wetland criteria and (b) dryland criteria. APPLICANT (OWNERS): Rivers Edge, LLC REPRESENTATIVE: Greg Lewicki BACKGROUND At the September 23, 2009 public meeting of the Garfield County Planning Commission the applicant, Rivers Edge, LLC, proposed a text amendment to the Unified Land Use Resolution of 2008 to modify certain standards of Section 7-840, Additional Standards Applicable to Gravel Extraction, specifically subsections E. Impacts to County Road System and H. Reclamation/Enforcement. During the public hearing Planning Staff presented the proposal and recommended denial of the changes due to confusing and vague language. Following testimony by the applicant, his representative, and other interested parties the Planning Commission decided to offer an alternative text to the Board of County Commissioners attempting to remove any vague and confusing language. The Commission completed a revision to subsection E and continued the public hearing to the October 14, 2009 Planning Commission hearing date to continue the discussion on the remaining text of subsection H. Based on the discussion and direction of the Planning Commission, Planning Staff invited the applicant, his representative, and county Legal Staff, to discuss revisions of the proposed text of subsection H. This collaborative effort resulted in a draft of subsection H which is attached to this memo. The intent was to create a document that is clear and concise meeting the intent of the original text while integrating some flexibility in future development of gravel resources. 1 TXTP 6010 — Draft of Plposed Text Amendment Revisio (PC) EXHIBIT a E.

APPLICANT (OWNERS): Rivers Edge, LLC REPRESENTATIVE: Greg Lewicki I. BACKGROUND The Applicant, Rivers Edge, is a landowner in Garfield County with land holdings located 1/2 mile east of the main interstate intersection of Rifle Colorado between the Colorado River and Interstate 70 (Section 15, Township 6 South, Range 93 West). The Applicant has a Special Use Permit pending for "Extraction, Storage, Processing, and Material Handling of Natural Resources" for a Gravel Pit operation on approximately 25 acres of a 93 -acre property. This Special Use Permit, under the provisions of the expired Zoning Resolution of 1978, is a request is for an expansion of an existing mining permit currently in place with the Division of Reclamation, Mining, and Safety. In addition to the State Permit, Garfield County requires a Special Use Permit. The Special Use Permit request was presented to the Planning Commission on June 24, 2009 and continued to September 23, 2009 to allow the applicant adequate time to process a text amendment addressing the concerns noted in the Special Use Permit staff report dated June 24, 2009. II. REQUEST The Applicant is requesting a text amendment to the recently adopted standards (Resolution 2009-53) for "Gravel Extraction" codified in Section 7-840. The text amendment proposal specifically impacts Section 7-840 E Impacts to County Road System and 7-840 H Reclamation Enforcement. 1 • • Section 7-840 E Impacts to County Road System; E. Impacts to County Road System (Current language) 3. The Applicant shall submit evidence of insurance for a minimum of $1,000,000 to cover any damages to public and private property, and Garfield County shall be named as an additional insured. 4. Roads used to access the construction site from the mine will be upgraded to withstand the additional traffic, and the permittee will prevent road damage and mitigate dust, under the supervision of the Road and Bridge Director. E. Impacts to County Road System — (Proposed Language Change) 3. If The Applicant's operation has direct access to a County Road, The Applicant shall submit evidence of insurance for a minimum of $1,000,000 to cover any damages to public and private property, and Garfield County shall be named as an additional insured. If The Applicant demonstrates that its operation will not directly enter a County Road or will not utilize the County Road system to a significant extent, a lesser amount of the $1,000,000 insurance can be agreed upon. The Applicant shall propose the amount if this demonstration is made. 4. Roads used to access the construction site from the mine will be upgraded to withstand the additional traffic, if needed, and the permittee will prevent road damage and mitigate dust, under the supervision of the Road and Bridge Director. Section 7-840 H Reclamation and Enforcement; H.) Reclamation/Enforcement (Current Language) Reclamation shall be done to create an aesthetically pleasing site or reclaimed area that will blend with or improve upon the surrounding areas. All applications shall submit a Reclamation Plan that specifically addresses the following aspects of reclamation: slopes, vegetation, lake / pond shape & character, wildlife habitat / agriculture, phasing and berms. Additionally, The State of Colorado Division of Reclamation, Mining and Safety has minimum standards for reclamation. For example, reclaimed slopes are typically required to be 3:1 or shallower. This standard creates stable slopes but does not necessarily result in a landscape that blends with the surroundings. The same is true for other aspects of reclamation. All Reclamation plans shall follow the following design criteria: 1. Slopes a) Wetland Criteria: Varied slopes predominantly 5:1 or shallower, at least 80% 5:1, and 25% 10:1 or shallower in wetland zone. b) Dryland Criteria: Varied slopes predominantly 5:1 or shallower, seamlessly blends with surrounding landscape. 2 • • Wetland Shelf Design: For areas rot adjacent to existing wetihnes Cottonwood Saplings Plantea' Or EKIstIng Trees Avoided 31 Pr aura:e Approximate Lake Surface Topsoil F eplacsd to Depth of 1.0' nd Fringo Stumps and Roots Placed in Piles ori the Lake Bottum fee Fish 1- dttst 2. Vegetation a) Wetland Criteria: Variation in revegetation, revegetation to include planting of trees and/or shrubs, if seedlings or sprouts plantings occur as part of phased reclamation and not just at the end of the mine life. Established trees or shrubs in final reclamation phase are at least 8' tall or 2" caliper trees or 5 gallon shrub containers. Active irrigation shall be employed in revegetation areas during the Life of the mine or until revegetation is self-sustaining. b) Dryland Criteria: Variation in revegetation, revegetation to include planting of trees and/or shrubs, if seedlings or sprouts plantings occur as part of phased reclamation and not just at the end of the mine life. Established trees or shrubs in final reclamation phase are at least 8' tall or 2" caliper trees or 5 gallon shrub containers. Active irrigation in revegetation areas during the life of the mine or until revegetation is self-sustaining. II) Reclamation/Enforcement - (Proposed Language Change) 1. Slopes a) Wetland Areas: In pits excavating gravel below the water table, and where a pit lake is part of the reclamation plan, wetlands shall be part of the reclamation plan, at least along the lake surface, unless good reason is shown to provide an alternate plan along the shoreline. If wetlands are part of the shoreline plan, the immediate area of wetland slopes shall be predominantly 5:1 or shallower, with at least 80% 5:1, and 20% 10:1 or shallower. The immediate area of wetland slopes is defined as 3 vertical feet above the shoreline and 3 vertical feet below the shoreline. The percentages are calculated along the perimeter of the reclaimed lakes. Exceptions to this requirement can be approved if good cause is shown. Examples of exceptions are agreed post -mine uses of lake recreation with boat dock facilities, discouraging of waterfowl habitat due to proximity to an airport, fishing embankments, PUDs, public parks and others. 3 ! • b) Dryland Areas: This area is defined as any area above a wetland shoreline or any non- irrigated area in the post -mine land use that will predominantly be used for rangeland grazing and wildlife habitat. These slopes shall be predominantly 5:1, meaning at least 85% of the slopes must be 5:1 or shallower, unless good reason is shown by the applicant to reduce this requirement. Examples of situations where a variance is allowed are a) where existing terrain slopes are steep, as in a older terrace gravel deposit, and it would not be possible to restore such shallow slopes, and b) where a proposed operation is within 10,000 feet of an airport runway and shallow slopes along a pit lake will encourage waterfowl, creating a safety issue for airplanes, c) where the resource is deemed very valuable, there is little or no backfill material available and a steeper slope will not result in any undesirable impacts. Other exceptions may exist but must be demonstrated by the Applicant. 2. Vegetation All revegetation efforts shall occur as part of phased reclamation. a) Wetland Criteria: Where wetlands are part of the reclamation plan, there shall be a variation in revegetation species, which shall be based on the ultimate goals of the reclaimed wetland areas. This is usually wildlife habitat; therefore, the species planted through seeding shall promote and enhance the wildlife that will be expected to use the wetland. Wetland seeding shall occur immediately before a lake is filled to prevent seed loss from wildlife consumption, wind and other means. Seeding shall be done by drilling or by hydroseeding methods. Broadcast seeding is not permitted. Revegetation of wetlands shall also include planting of trees, willows and/or shrubs. Trees may be eliminated from the plan if the Applicant can demonstrate that existing trees avoided in the mining operation, combined with tree sapling planting, will provide the same visual and wildlife effect. This planting work should be done immediately after lake filling so that the trees are planted at the proper elevation. Established trees in final reclamation phase for each lake are shall be at least 8' tall or 2" caliper trees. Shrubs are 5 gallon shrub containers or live willow cuttings can also be used. Irrigation is not required in the wetland areas. b) Dryland Criteria: The plant species to be employed in the dryland areas should be based on the intended post -mining land use. For the normal dryland use of animal grazing and wildlife habitat, variation and species diversity in revegetation are important. Revegetation shall include a mixture of grasses, forbs and shrubs, and seeding methods shall either use drilling with crimp mulching or hydroseeding. Mulch shall be weed free and shall be applied at a rate of no less than 3000 pounds per acre. Hydroseeding with hydromulching and tackifier is normally used on steep slopes. Hydromulching shall be a minimum rate of 2000 pounds of wood fiber per acre. Active irrigation in revegetation of dryland areas shall not take place after seeding unless the following conditions exist: a) If drought conditions persist after seeding, irrigation shall be used to provide what precipitation would normally be experienced and b) This supplemental irrigation shall only be implemented during the 1st three years after seeding as required in (a) above. If initial seeding efforts fail, supplemental seeding may be needed and supplemental irrigation shall be used again if less than average precipitation is experienced. • • III. COMPREHENSIVE PLAN LAND USE GOALS AND OBJECTIVES The Comprehensive Plan of 2000 discusses basic policy direction for land use in Garfield County. The following are some of the Goals, Objectives, and Policies that apply to this proposed text amendment to the Unified Land Use Resolution (2008) referenced by the item number of Section III: Goals, Objectives, Policies, and Programs. 4.0 COMMERCL4L & INDUSTRIAL USES ISSUES: Adequate infrastructure requirements are often not required prior to project approval or are simply not available at a particular site; GOALS: Industrial: Garfield County will encourage the development of a diversified industrial base for the County which recognizes the human resources, natural resources and physical location -to -market capabilities of the community, and which further recognizes and addresses the social and environmental impacts of industrial uses. Future, long-term commercial and industrial development in western Garfield County and at interchanges along 1-70. OBJECTIVES: 4.1 To ensure that commercial and industrial developments are compatible with adjacent land uses and mitigate impacts identified during the plan review process. 4.6 Ensure that Zoning Regulations addressing Commercial and Industrial uses reflect the changing land use patterns and demographics of the County and encourage the further diversification of the County economy. 4.7 Ensure a commercial and industrial development policy that is environmentally sound and acceptable to County residents and policy makers. POLICIES: 4.4 The project review process will include a preliminary assessment of the projected traffic impact associated with all commercial and industrial projects. 8.0 NATURAL ENVIRONMENT ISSUES: Development should respect the natural contours and drainage patterns on each individual project site. GOALS: The reclamation of land after extraction processes. Protection of watersheds and flood plains. 5 • • OBJECTIVES: 8.2 Proposed projects will be required to recognize the physical constraints of the land and design projects in a manner that is compatible with the physical environment. 8.4 River fronts and riparian areas are fragile components of the ecosystem and these areas require careful review in the planning process. POLICIES: The County will require development with river frontage to address the issue through physical design in a way which will protect fragile wetlands and scenic resources and protect floodplain from encroachment. 9.0 NATURAL RESOURCE EXTRACTION ISSUES: The relationship between previously approved mining operations and residential development has resulted in visual, noise, and traffic compatibility issues. The County must be proactive in reacting to market conditions that will impact the level, location, and scale of mineral extraction within the County. OBJECTIVES: 9.3 The County will ensure that mineral extraction activities will not adversely affect the natural environment, including air quality, water quality, wildlife habitat or important visual resources. POLICIES: 9.1 Garfield County, to the extent legally possible, will require adequate mitigation to address the impacts of mineral extraction on adjacent land owners. These measures may include the following: A. Landscaping and screening; B. Modification of phasing or area to be mined; C. Roadway improvements and signage; D. Safe and efficient access routes; E. Drainage improvements to protect surface and groundwater. 9.2 Garfield County, in coordination with relevant special districts, authorities and municipalities, will require that developers of energy or mineral extraction processes finance the construction and operation of any public improvements which, now or in the future, will be required by their project. RELATIONSHIP TO THE COMPREHENSIVE PLAN The proposed text amendment is not site-specific though, as proposed, would benefit the current applicant in his gravel mining activity. The current language of Section 7-840 meets the Goals, Objectives, and Policies of the Garfield County Comprehensive Plan. The proposed changes to Items E and H of Section 7-840 may conform to the policies of the Comprehensive Plan but interject a great deal of vague language which could be difficult to implement and enforce. Additional discussion about the proposed text amendment language is offered below in the Staff Analysis. 6 • IV. CONSISTENCY WITH EXISTING COUNTY REGULATIONS The proposed text amendment alters the standards for Section 7-840 Gravel Extraction (Items E and H) and affects specific requirements for any Gravel Mining operation impacts to County Roads and Reclamation. While each Land Use Change Permit must demonstrate conformance with the applicable county regulations and state standards, the proposed text amendment introduces a great deal of vagueness, rather than certainty, in the process of obtaining a permit for Gravel Extraction. Development standards are listed for all Land Use Change Permits and encompass a broad range of impacts including, but not limited to, Access and Roadways, Agricultural Land, Wildlife Habitat Areas, Wetlands and Waterbodies, Water Quality standards, Erosion and Sedimentation, Drainage, Stormwater Run -Off, Air Quality, Wildfire Hazards, Natural Hazards and Geologic Hazards, Archeological, Paleontological and Historical Importance as well as Reclamation. The proposed text changes affect the requirements for a specific use and alters an applicant's responsibility for on-site and off-site impacts inconsistent with similar requirements for other types of uses. V. STAFF ANALYSIS The Unified Land Use Resolution of 2008 has specific standards which were recently adopted on July 7, 2009 in Resolution number 2009-53. The current proposal is to modify and expand on the listed standards for Gravel Extraction located in Section 7-840 and more specifically items E and H. Section 7-840 E Impacts to County Road System, discusses traffic volume, routing, and potential for damage to the County Road System and specifically items 3 and 4 that deal with bonding and mitigating measures for road impacts. The changes are minor but create uncertainty by allowing a reduction in responsibility. The proposed text reads (vague language highlighted); E. Impacts to County Road System — (Proposed Language Change) 3. If The Applicant's operation has direct access to a County Road, The Applicant shall submit evidence of insurance for a minimum of $1,000,000 to cover any damages to public and private property, and Garfield County shall be named as an additional insured If The Applicant demonstrates that its operation will not directly enter a County Road or will not utilize, the County Road system to a significant extent, a lesser amount of the $1,000,000 insurance can be agreed upon. The Applicant shall propose the amount if this demonstration is made. 4. Roads used to access the construction site from the mine will be upgraded to withstand the additional traffic, if needed, and the permittee will prevent road damage and mitigate dust, under the supervision of the Road and Bridge Director. With the proposed changes it is implied that Gravel Mining activity may not affect the road network and, if proven to the Board, a reduced insurance and/or level of responsibility will allow a reduction in the bonding and responsibility for off-site impacts. This may be difficult to implement and monitor. To say activity on a site will not impact surrounding roads has no merit. In the particular case of Rivers Edge, LLC, it would benefit the land owner since the claim is that a direct access to the State Highway system will not affect the County Road system but the language change affects all gravel mining activity in Garfield County and not just the Rivers Edge site. 7 • • Section 7-840 H Reclamation/Enforcement, the proposed changes to this section significantly expands the discussion concerning slopes, adds definitions within the body of the standards, changes the required vegetation and irrigation standards, and adds a great deal of uncertainty by using vague language that can't be readily implemented. Item H, as proposed is (vague language highlighted); H) Reclamation/Enforcement - (Proposed Language Change) 1. Slopes a) Wetland Areas: In pits excavating gravel below the water table, and where a pit lake is part of the reclamation plan, wetlands shall be part of the reclamation plan, at least along the lake surface, unless good reason is shown to provide an alternate plan along the shoreline. If wetlands are part of the shoreline plan, the immediate area of wetland slopes shall be predominantly 5:1 or shallower, with at least 80% 5:1, and 20% 10:1 or shallower. The immediate area of wetland slopes is defined as 3 vertical feet above the shoreline and 3 vertical feet below the shoreline. The percentages are calculated along the perimeter of the reclaimed lakes. Exceptions to this requirement can be approved if good cause is shown. Examples of exceptions are agreed post -mine uses of lake recreation with boat dock facilities, discouraging of waterfowl habitat due to proximity to an airport, fishing embankments, PUDs, public parks and others. b) Dryland Areas: This area is defined as any area above a wetland shoreline or any non- irrigated area in the post -mine land use that will predominantly be used for rangeland grazing and wildlife habitat. These slopes shall be predominantly 5:1, meaning at least 85% of the slopes must be 5:1 or shallower, unless good reason is shown by the applicant to reduce this requirement. Examples of situations where a variance is allowed are a) where existing terrain slopes are steep, as in a older terrace gravel deposit, and it would not be possible to restore such shallow slopes, and b) where a proposed operation is within 10,000 feet of an airport runway and shallow slopes along a pit lake will encourage waterfowl, creating a safety issue for airplanes, c) where the resource is deemed very valuable, there is little or no backfill material available and a steeper slope will not result in any undesirable impacts. Other exceptions may exist but must be demonstrated by the Applicant. 2. Vegetation All revegetation efforts shall occur as part of phased reclamation. a) Wetland Criteria: Where wetlands are part of the reclamation plan, there shall be a variation in revegetation species, which shall be based on the ultimate goals of the reclaimed wetland areas. This is usually wildlife habitat; therefore, the species planted through seeding shall promote and enhance the wildlife that will be expected to use the wetland. Wetland seeding shall occur immediately before a lake is filled to prevent seed loss from wildlife consumption, wind and other means. Seeding shall be done by drilling or by hydroseeding methods. Broadcast seeding is not permitted. Revegetation of wetlands shall also include planting of trees, willows and/or shrubs. Trees may be eliminated from the plan if the Applicant can demonstrate that existing trees avoided in the mining operation, combined with tree sapling planting, will provide the same visual and wildlife effect. This planting work should be done immediately after lake filling so that the trees are planted at the proper elevation. Established trees in final reclamation phase for each lake are shall be at least 8' tall or 2" caliper trees. Shrubs are 5 gallon shrub containers or live willow cuttings can also be used. Irrigation is not required in the wetland areas. 8 • • b) Dryland Criteria: The plant species to be employed in the dryland areas should be based on the intended post -mining land use. For the normal dryland use of animal grazing and wildlife habitat, variation and species diversity in revegetation are important. Revegetation shall include a mixture of grasses, forbs and shrubs, and seeding methods shall either use drilling with crimp mulching or hydroseeding. Mulch shall be weed free and shall be applied at a rate of no less than 3000 pounds per acre. Hydroseeding with hydromulching and tackifier is normally used on steep slopes. Hydromulching shall be a minimum rate of 2000 pounds of wood fiber per acre. Active irrigation in revegetation of dryland areas shall not take place after seeding unless the following conditions exist: a) If drought conditions persist after seeding, irrigation shall be used to provide what precipitation would normally be experienced and b) This supplemental irrigation shall only be implemented during the lst three years after seeding as required in (a) above. If initial seeding efforts fail, supplemental seeding may be needed and supplemental irrigation shall be used again if less than average precipitation is experienced. The proposed changes to Item H discuss two elements of Reclamation: slope and vegetation. In the proposed text related to slope, two definitions are introduced for "wetland slope" and "dryland area" which should be new definitions to Article XVI rather than in the body of standards. Also, terms and expressions such as "... unless good reason..." and "... where the resource is deemed very valuable." are introduced which are vague and open to endless interpretation. Additionally, the proposed text offers "exceptions" and "variances" to the standards for "good cause" and "good reasons" but not identifying an equitable standard for either case. In item H 2, Vegetation, additional language is added reducing the requirement for tree plantings and irrigation in wetland areas plus contradictory language for seeding before lake filling and then a following statement that planting should occur after lake filling. In dryland areas the requirement for active irrigation is not required unless there is drought and then only if within three years after seeding. Failure of the initial seeding in dryland areas may require additional replanting efforts but it would be difficult to set a security amount and date given the uncertainty of weather. VI. STAFF RECOMMENDATION Planning Staff recommends the Planning Commission forward a recommendation of denial to the Board of County Commissioners for the proposed text amendment to Section 7-840 Gravel Extraction. The proposed language would be difficult to interpret, enforce, and implement creating a scenario of constant negotiation between Garfield County and a future gravel pit developer. The proposed text amendment may serve an individual property owner but does not offer adequate standards and safeguards for the residents of Garfield County. VII. SUGGESTED FINDINGS TO THE BOARD OF COUNTY COMMISSIONERS I. That the hearing before the Planning Commission was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard. 2. That the proposed text amendment is not in the best interest of the health, safety, morals, 9 • • convenience, order, prosperity and welfare of the citizens of Garfield County. 3. That the application has met the requirements of the Garfield County Unified Land Use Resolution of 2008, as amended. 4. That the proposed text amendment uses vague and contradicting language and would be difficult to interpret and enforce. 5. That a new proposal with concrete and well defined standards may be entertained for future consideration. 10 August 3, 2009 Greg Lewicki Greg Lewicki & Associates 11541 Warrington Court Parker, CO 80138 BUILDING & PLANNING DEPARTMENT Re: Request for a Text Amendment to Article 7 Standards, Section 7-917: Additional Standards Applicable to Gravel Extraction Amending Article 7 Standards By Modifying the language of Section 7-917 E Impacts to County Road System, Items 3 and 4 and; Modifying the language of Section 7-917 H Reclamation/Enforcement Items 1 and 2 Dear Mr. Lewicki, This office is in receipt of your Text Amendment application submitted by you for a request to amend the text of Article VII — Section 7-917: Additional Standards Applicable to Gravel Extraction.

Reclamation/Enforcement (Current Lanouage) 4-/ 7,64:1 G'p-arv; aCc Reclamation shall be done to create an aesthetically pleasing site or reclaimed area that will blend with or improve upon the surrounding areas. All applications shall submit a Reclamation Plan that specifically addresses the following aspects of reclamation: slopes, vegetation, lake / pond shape & character, wildlife habitat / agriculture, phasing and berms. Additionally, The State of Colorado Division of Reclamation, rvlining and Safety has minimum standards for reclamation. For example, reclaimed slopes are typically required to be 3:1 or shallower. This standard creates stable slopes but does not necessarily result in a landscape that blends with the surroundings. The same is true for other aspects of reclamation. All Reclamation plans shall follow the following design criteria: 1. Slopes a) Wetland Criteria: Varied slopes predominantly 5:1 or shallower, at least 80% 5:1, and 25% 10:1 or shallower in wetland zone. b) Dryland Criteria: Varied slopes predominantly 5:1 or shallower, seamlessly blends with surrounding landscape. 2. Vegetation a) Wetland Criteria: Variation in revegetation, revegetation to include planting of trees and/or shrubs, if seedlings or sprouts plantings occur as part of phased reclamation and not just at the end of the mine life. Established trees or shrubs in final reclamation phase are at least 8' tall or 2" caliper trees or 5 gallon shrub containers. Active irrigation shall be employed in revegetation areas during the life of the mine or until revegetation is self-sustaining. b) Dryland Criteria: Variation in revegetation, revegetation to include planting of trees and/or shrubs, if seedlings or sprouts plantings occur as part of phased reclamation and not just at the end of the mine life. Established trees or shrubs in final reclamation phase are at least 8' tall or 2" caliper trees or 5 gallon shrub containers. Active irrigation in revegetation areas during the life of the mine or until revegetation is self-sustaining. 3. Lake / Pond Shape and Character: Reclamation with multiple ponds or lakes with substantial islands or peninsula (at least 20% of total surface) to break up surface, undulation of shorelines provides natural appearance. £71 H) Reclamation/Enforcement - (Proposed Language Change) 1 Slopes a) Wetland Areas: In pits excavating gravel below th water table, and where a pit lake is part • the reclamation • Ian wet! ds shall be part of the reclamation plan, t leas on the lake surfac , unle good reason is shown to provide an alterna -plan-along-the shoreline. If we a i s are part of the shoreline plan, the immediate area of wetland slopes shall be predominantly 5:1 or shallower, with at least 80% 5:1, and 20% 10:1 or shallower. The immediate area of wetland slopes is defined as 3 vertical feet above the shoreline and 3 vertical feet below the shoreline. The percentages are calculated along the perimeter of the reclaime lakes. • t,:. xceptions to this requireme t_'. • •°elapproved ifooa cause fiof � Examples of exceptions ar at reed )ost-mine uses of lake recreation with �d-4(t� boat _clnc-k-faciliti-s, • iscour • g of waterfowl habitat due to proximity to an airport, fishing embankments, PUDs, public parks and others. - \ �b) Dryland Areas: This area is defined as any area above a we �t' shoreline or any non -irrigated area in the post -mine la use that will predominantly be used for rangeland grazing a d -_wildlife habitat. These slopes shall be predominantly 5.1, e�'n• at�least :5% f the slopes must be 5:1 or shallower, unlessoomn d re so is o n •y the applicant to reduce this requirement. Examples of situations where a variance is allowed are a) where existing terrain slopes are steep, as in Polder terrace gravel deposit, and it would not be possible to restore such shallow slopes, and b) where a proposed operation is within 10,000 feet of an airport runway and shallow slopes along a pit lake will encourage aterf•wl, c - • a safety issue for airplanes, c) where the resource is ( deeme• ery valuable there is little or no ria/ available and a s eeper not result in an 4Indesirable imp_acts. Other exceptions may exist but must be demonstrated by the Applicant. 7 2. Vegetation All revegetation efforts shall occur as part of phased reclamation. a) Wetland Criteria: Where wetlands are part of the reclamation plan, there 4 shall be a variation in revegetation species, which shall be based on the ultimate goals of the reclaimed et ar asp--T'sally-wildlife— habitat; therefore, the species pl nted throu h seedin hall promote and enhance the wildlife that will be expected to use the wetland. Wetland seeding shall occur immediately before a lake is filled to prevent seed loss from wildlife consumption, wind and other means. Seeding shall be done by drilling or by hydroseeding methods. Broadcast seeding is not permitted. Revegetation of wetlands shall also include planting of trees, willows and/or shrubs. Trees may be eliminated from the plan if the Applicant can demonstrate that existing trees avoided in the mining • • operation, combined with tree sapling planting, will provide the same visual and wildlife effect. This planting work should be done immediately after lake filling so that the trees are planted at the proper elevation. Established trees in final reclamation phase for each lake are shall be at least 8' tall or 2" caliper trees. Shrubs are 5 gallon shrub containers or live willow cuttings can also be used. Irrigation is not required in the wetland areas. b) Dryland Criteria: The plant species to be employed in the dryland areas should be based on the intended post -mining land use. For the normal dryland use of animal grazing and wildlife habitat, variation and species diversity in revegetation are important. Revegetation shall include a mixture of grasses, forbs and shrubs, and seeding methods shall either use drilling with crimp mulching or hydroseeding. Mulch shall be weed free and shall be applied at a rate of no less than 3000 pounds per acre. Hydroseeding with hydromulching and tackifier is normally used on steep slopes. Hydromuiching shall be a minimum rate of 2000 pounds of wood fiber per acre. Active irrigation in revegetation of dryland areas shall not take place after seeding unless the following conditions exist: a) If drought conditions persist after seeding, irrigation shall be used to provide what precipitation would normally be experienced and b) This supplemental irrigation shall only be implemented during the 1st three years after seeding as required in (a) above. If initial seeding efforts fail, supplemental seeding may be needed and supplemental irrigation shall be used again if less than average precipitation is experienced. I ain available at the number shown at the top of the letter if you have any questions. Sincerely, ,ewc,d6 Greg Lewicki, P. E. Greg Lewicki and Associates • • 4.0 RECLAMATION The mineral rules and regulations, published by the Colorado Mined Land Reclamation Board, establish the requirements for reclamation of mined lands in the State of Colorado. These requirements must be satisfied and adhered to for the life of the mine in order to obtain a mining permit for the extraction of gravel. The requirements presented in this document supplement those of the Mined Land Reclamation Board and recognize the special riverine corridor stability needs. In no case do the requirements of this document imply that the requirements of the Mined Land Reclamation Board, as a minimum, should not be adhered to. 4.1 RECREATIONAL CRITERIA When gravel pit lakes are to be reclaimed as recreational amenities, the side slopes of the lakes should be sloped at a minimum of 5 horizontal to 1 vertical (5H:IV) for a distance from the top of the berm to a point 8 feet under the normal water surface. There the slope can be at 2H:IV to the lake bottom. Where concentrated swimming is to be actively encouraged, side slopes of 20H:IV, or flatter, are recommended in the beach areas. Irregularities in the lake shorelines are required for variety in the environment and to enhance wildlife habitat. These irregularities also help protect the banks from wave action. Other recreational or wildlife features, such as islands, may be required by local government. Corridors must be provided for access to recreational areas and maintenance trails. These corridors should be incorporated into riverside berms, or through other portions of the lease properties if developed as part of a overall recreational master plan by the operators or by the local governments. A corridor of 100 -feet minimum is recommended to accommodate multiple recreational uses. This river corridor minimum width should be maintained on both sides of the river for its entire length. The recreational corridor may be contained within the required top width of riverside berms. 4.2 REVEGETATION CRITERIA Revegetation of all areas not receiving other stabilization techniques will be required. The revegetation should be installed in conformance with the Guidelines for Vegetation and must meet the approval of the Colorado Mined Land Reclamation Board. The goal of revegetation is to reestablish the historic ground cover as closely as possible to promote the return of the historic animal population, to protect areas from erosion by wind and water and to improve the aesthetics of the area. To accomplish this, revegetation must be undertaken at the earliest opportunity. Revegetation must begin as soon as the slope has attained its required configuration subject to the seeding criteria specified in Guidelines for Vegetation. When slopes are in areas which will be inactive for periods in excess of six months vegetation must be re-established. UD&FCD GRAVEL GUIDELINES 12/17/87 4-1 • ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION Section 7-917 Additional Standards Applicable to Gravel Extraction (This entire section was added to these regulations via Resolution 2009 - ). A. Water Quantity & Quality Impacts / Floodplain Impacts If a gravel pit is located within the floodplain there is a reasonable chance that it could be flooded during its operational life. Equipment, machinery, fuel etc could become pollutant sources in the case of a flood. In addition, if the pit is located near the floodway of a river there is the possibility that in a flood a gravel pit could alter the natural course of a river. This can have negative impacts on a river ecosystem and unknown impacts on nearby landowners. Every Application for gravel extraction shall address the following: 1. When the proposal is near a river or stream the Applicant is required to submit an analysis by a professional engineer showing the boundaries of the floodplain and the floodway in the area of the pit. 2. Provide a Stormwater Management Plan that demonstrates how the project will not adversely affect surface or groundwater resources. Additionally, provide a Sediment and Erosion Control plan that demonstrates what best management practices will be used in the project. 3. In all cases, an application for a gravel mining operation shall include a Spill Prevention Counter Measure and Control Plan (SPCC) that provides a program that handles spills of hazardous materials as well as local contact information for responsible personnel at the facility. 4. No land use change application shall be accepted by the County without a letter from the applicable fire protection district stating that the proposed project has been adequately designed to handle the storage of flammable or explosive solids or gases and that the methods comply with the national, state and local fire codes. 5. No materials or wastes shall be deposited upon a property in such form or manner that they may be transferred off the property by any reasonably foreseeable natural causes or forces. 6. Development in 100 year Floodplain: Floodways - located within areas of special flood hazard established in as found in the report entitled the Flood Insurance Study, Garfield County, Colorado, Unincorporated Areas dated August 2, 2006 and the accompanying flood maps entitled Flood Boundary Maps, Floodway Maps and Flood Insurance Rate Maps, Garfield County, Colorado, Unincorporated Areas, as the same may be from time to time amended through the Zone District Amendment GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED 7-147 October 13, 2008 • ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION procedure in Article IV are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles and erosion potential, the following provisions shall apply: a) Encroachments are prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase or decrease in flood levels within the County during the occurrence of the base flood discharge. b) All new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Section 7- 701(G) and Section 7-701(H). c) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Regulations, the County may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the Applicant obtains a Letter of Map Revision (LOMR) for a floodway revision through FEMA and that no mining activity shall occur until FEMA has approved a Letter of Map Revision (LOMR). d) In all cases, there shall be no storage of fuel or hazardous materials including concrete / asphalt batch plants within the floodway. 7. Standards for Areas of Shallow Flooding: Located within the areas of special flood hazard which are areas designated as shallow flooding also known as the flood -fringe as found in the report entitled the Flood Insurance Study, Garfield County, Colorado, Unincorporated Areas dated August 2, 2006 and the accompanying flood maps entitled Flood Boundary Maps, Floodway Maps and Flood Insurance Rate Maps, Garfield County, Colorado, Unincorporated Areas, as the same may be from time to time amended through the Zone District Amendment procedure in Article IV. These areas have special flood hazards associated with base flood depths of 1 to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flow may be evident. GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED 7-148 October 13, 2008 •ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply: a) All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified). b) All new construction and substantial improvements of non- residential structures; 1. have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified), or; 2. together with attendant utility and sanitary facilities be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads of effects of buoyancy. c) A registered professional engineer shall submit a certification to the County Floodplain Administrator that the standards of this Section have been fully satisfied. d) Require within Zones AH or AO adequate drainage paths around structures on slopes, to guide flood waters around and away from proposed structures. 8. The proposed operation will be located a sufficient distance from other mining operations so as not to create cumulative impacts to the integrity of the water course. The Board of Commissioners will determine sufficiency of distance. 9. In -stream mining is not permitted. 10.A11 applications shall provide a de -water / discharge plan that provides a detailed graphic representation of how dewatering operations shall occur. This plan shall demonstrate that the discharge will not exceed state standards for discharge into a water course or wetland. GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED 7-149 October 13, 2008 a• ARTICLE VI I STANDARDS 7-917 GRAVEL EXTRACTION 11.In all cases, the Application shall contain proof that the operation has adequate legal and physical water for the proposed application. B. Air Quality Fugitive dust from disturbed areas is one of the primary causes of gravel pit air pollution. The potential for soil erosion potential also increases proportionate to the amount of disturbed area. Gravel Pits should make an active effort to reduce disturbed area through phased reclamation, efficient operations, and landscaping. Disturbed acreage can also provide a measure of visual impact when the operation is located on valley floor and there are residences on nearby hillsides. Opacity shall not exceed 20%. 1. All gravel operations in the County shall comply with applicable County, State, and Federal regulations regulating air pollution and shall not be conducted in a manner constituting a public nuisance or hazard. 2. Impacts on adjacent land from the generation of vapor, dust, smoke, or other emanations. All applications shall demonstrate how they will meet County, State, and Federal air pollution regulations. Any repair and maintenance activity requiring the use of equipment that will generate odors beyond the property boundaries will be conducted within a building at any time or outdoors during the hours of 7:00 AM to 8:00 PM, Monday - Saturday. 3. The proposed operation will be located a sufficient distance from other mining operations so as not to create cumulative impacts to air quality. 4. No application shall be approved until the Applicant submits evidence that all plants and processing equipment shall have current Colorado Department of Public Health and the Environment (CDPHE) Air Pollution Permits and shall meet current CDPHE emissions standards for air and water. C. Noise / Vibration All gravel extraction operations in the County shall comply with applicable County, State, and Federal regulations regulating noise pollution and shall not be conducted in a manner constituting a public nuisance or hazard. Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. 1. An Applicant shall submit a noise study that demonstrates the proposed gravel operation can meet the requirements in the matrix below based on GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED 7-150 October 13, 2008 • ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION measuring the sound levels of noise radiating from a property line at a distance of 25 feet or more beyond the subject property. (The image to the right shows a dashed line at 25 feet beyond the subject property where noise shall be measured.) 2. Note, the dB(A) threshold shown below shall be that of the receiver and not that of the emitter. For example, while the gravel operation would be considered an 1 , industrial operation, the dB(A) levels shown below are measured according to the neighboring uses so that if a residential use was located adjacent to the operation, sound levels could not exceed 55 dB(A) from 7 AM to 7 PM and 50 dB(A) from 7 PM to 7 AM. Zone 7 am to 7 pm 7 pm to 7 am Residential 55 dB(A) 50 dB(A) Commercial 60 dB(A) 55 dB(A) Light Industrial 65 dB(A) 70 dB(A) Industrial 80 dB(A) 75 dB(A) 3. Every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located. D. Visual Impacts All applications for gravel extraction shall address the following: 1. All gravel operations proposed to mine areas greater than 30 acres shall be designed in multiple phases in order to minimize the visual impact of the gravel pit primarily by logical "sequencing" and "overall layout" of the pit's design. Scale, Office / Parkin GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED October 13, 2008 7-151 • ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION 2. Design of the proposed use including the storage of heavy equipment is organized to minimize impact on adjacent uses of land through installation of screen fences, berming, and/ or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character. 3. At the discretion of the County Commissioners, all outdoor storage facilities may be required to be enclosed by fence, landscaping or wall adequate to conceal such facilities from adjacent property. 4. New long-term (more than one year) mining operations will minimize visual impacts along entryways to growth centers. Planning Commission and/or the Board of County Commissioners will determine sufficiency of minimization. 5. All application shall include a "Berming, Screening, and Buffering Plan" to aid in visual screening. Provisions in this plan shall be in place prior to commercial mining. The Applicant shall invite the Staff from the County Building and Planning Department to the site to inspect that the installation occurred pursuant to the plan presented to the Board of County Commissioners prior to the commencement of any commercial activity and issuance of a land use change permit. 6. All lighting shall be the minimum necessary, directed inward and downward towards the property. 7. Unless otherwise determined by the Board of County Commissioners, mining operations shall be allowed to progress so long as the previous pit has been reclaimed within 6 months after the commencement of the new pit mining operation. If the reclamation has not commenced in six months or has been completed within eighteen (18) months, all mining operations on the property shall stop until the reclamation / revegetation has occurred to the satisfaction of the County. Completion, including but not limited to top -soiling, seeding, mulching, sapling planting, and water filling of the lake, shall be determined by the provisions contained within the reclamation plan approved by the Board of County Commissioners. E. Impacts to County Road System 1. All applications for a gravel extraction operation shall submit a traffic impact study prepared by a professional traffic engineer that identifies GARFIELD COUNTY UNIFIED LAND USE RESOLUTION, AS AMENDED 7-152 October 13, 2008 • • ARTICLE VII STANDARDS 7-917 GRAVEL EXTRACTION projected volumes of traffic through the life of the project, expected haul routes and any improvements street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use. These improvements shall either be in place or shall be constructed in conjunction with the proposed use. 2. Truck traffic will not access the mining operation through residential, or commercial areas, or such traffic will be mitigated. 3. The Applicant shall submit evidence of insurance for a minimum of $1,000,000 to cover any damages to public and private property, and Garfield County shall be named as an additional insured. 4. Roads used to access the construction site from the mine will be upgraded to withstand the additional traffic, and the permittee will prevent road damage and mitigate dust, under the supervision of the Road and Bridge Director. 5. The Applicant shall obtain driveway access permitls issued by Garfield County Road & Bridge Department at specific locations to be approved by the Road and ridge Department. These permits shall have conditions specific to the driveway/s. This may include stop sign/s at entrance to County Road. The stop signs and installation shall be as required in the MUTCD (Manual on Uniform Traffic Control Devices). Paved or concrete apron/s shall also be required as specified by the issued permit/s. 6. If road damage on a County Road becomes evident due to the traffic generated from the gravel pit operation, the Road and Bridge Department shall require that repair or replacement of the road surface as determined by Garfield County Road & Bridge Department become the responsibility of the owners or operators of the gravel pit operation. F. Impacts to Wildlife 1. The Applicant shall demonstrate the presence or absence of Threatened and Endangered species as well as the presence or absence of critical habitats for Threatened and Endangered species. 2.
