DEVELOPMENT SERVICES DEPARTMENT BUTTECOUNTY INITIAL STUDY AND PROPOSED MITIGATED NEGATIVE DECLARATION FOR THE AEON HARVEST GRADING PERMIT HARVEST GRD13-0010 (APN # 058-650-016) December 2014 2. The maximum height of cut is approximately 6 feet and fill is 4.5 feet. The maximum and minimum slope of the work site is Cuts (H:V) 2:1 maximum, 4:1 minimum; Fills 2:1 maximum, 4:1 minimum. A site-specific Erosion and Sediment Control Plan (ECP) is a part of the proposed grading plan, and Best Management Practices (BMPs) meeting the requirements of the State Department of Transportation (CalTrans) standard specifications, May 2006 were installed on-site and are incorporated into the project description. The Grading Plan identifies BMP's of silt fencing, straw wattles, and hydroseeding. Alternative BMP's ' for leveled areas are the addition of clean 2" rock. BMPs stabilize the site for water quality protection and erosion control, if needed. The purpose of the Erosion and Sediment Control Plan is to avoid water quality impacts off-site as the result of a storm event. Conservation Measure CM#1 (Stormwater BMBI Conservation Measure #1 is a list of BMPs that have been incorporated into the proposed Grading Plan, by the applicant: 1. If one or more acres of ground is to be disturbed, a permit must be obtained from the state water resources control board prior to construction. 2. All erosion control measures shall conform to the Caltrans standard specifications May 2006 and the erosion control plans shown on the construction drawings. Interim erosion control measures may be needed and shall be installed during construction to assure adequate erosion control facilities are in place at all times. 4. All slopes with disturbed soils greater than 10% that are free of vegetation shall have earth guard applied or mulch spread and tacked down prior to a 30% chance of rain. 5. Dust control measures in the form of water application to all exposed soil surfaces to prevent the transport of soil from exposed surfaces on construction sites in the form of airborne particulates. Watering of exposed soil surfaces shall occur at least twice daily, preferably in the late morning and after work is done for the day. All clearing, grading," earth moving or excavation activities shall cease when winds exceed 15 mph averaged over 1 hour. 6. To minimize the tracking of mud and dirt and to stabilize the point of ingress/egress by construction vehicles the contractor should place 4" to 6" angular rock with a minimum depth of 12" in conjunction with an underlay of filter fabric. Any soil material carried onto street surfaces by construction equipment shall be removed on a daily basis. (broom clean- do not use water to wash the street) If equipment traffic is minimal, stabilized entrance may not be needed. Any sediment tracked off the property and onto paved roadways shall be swept immediately after each vehicle leaves the site. 7. Haul trucks shall be covered with tarpaulins or other effective covers at all times. 8. If the construction site is to remain inactive longer than 14 days then the site shall be stabilized by applying "earth guard" or seeded and watered until grass cover is grown. APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 2 9. Inspect sediment control devices before each storm to verify they are in proper order. Inspect the sediment control devices after each storm, removing collected sediment and repairing deficiencies. 10. During long periods of rain and high intensity rainfall bmp's may become clogged. Extreme care should be taken to clean BMP's to reduce fugitive discharge and potential flooding. 11. Applicant may remove temporary BMP's (wattles and silt fencing) once permanent BMP's have been established. 12. Native seed and erosion control matting shall be applied to all disturbed areas that are not subject to heavy wear from construction equipment or other vehicles. Irrigation will be performed by hand watering. Seed and mulch shall be kept moist at all times until germination has occurred. Seed should be in conformance with the California State Seed Law and applied at the following rate: Seed - Melica Californica: 15 lbs/acre Fiber - 100% wood fiber- 2,000 lbs/acre Tack - Scilium based "M" binder 120 lbs/acre The project includes an Erosion and Sediment Control Plan (Figure 2), which is part of the Grading Plan. The following is a list of measures that will be implemented, as part of the Erosion and Sediment Control Plan: 1. If BMP's are damaged in a storm, repairs should be completed within 72 hours. Care should be exercised to minimize damage and protected areas while making repairs. 2. If BMP's have failed, or are ineffective, notify the owner/contractor to modify the BMP or specify an alternative. The modification or alternative should be installed within 72 hours of approval 3. If seeds fail to germinate, or they germinate and die, the area must be re -seeded, fertilized, and mulched within the planting season. Not less than half the original application rate should be applied. 4. Straw wattles shall have a minimum functional longevity of 1 year and shall be repla ced annually if required beyond 1 year. Upon permanent stabilization, and approval of the engineer, temporary BMPs may be removed if no longer needed. APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 3 RMT-TV.-ITOUTT.777 M-#31116 M_ The project also includes dust suppression measures to reduce dust and particulate matter associated with grading activities. These include: 1. Conduct daily cleanup. This practice shall include removal of mud and dust carried onto street surfaces by construction vehicles. During clearing grading, earth -moving, excavation, or transportation of cut or fill materials, water trucks or sprinkler systems are to be used to prevent dust from leaving the site and to create a crust after each day's activities cease. 2. Cover haul trucks with tarpaulins or other effective covers at all times, except when loading or unloading materials. 3. Water all exposed earth surfaces. This practice shall be conducted at a minimum in the late morning and at the end of the day. Further, the frequency of watering shall increase if required by the Butte County Air Pollution Control District. 4. All clearing, grading, earth -moving, or excavation activities shall cease when winds exceed 15 mph averaged over 1 hour. 5. The area disturbed by demolition, clearing, grading, earth -moving, or excavation operations shall be minimized at all times. 6. Portions of the construction site to remain inactive longer than a period of 14 days shall be seeded and watered until grass cover is grown. 7. The applicant shall minimize construction -related exhaust emissions by maintaining construction equipment engines in good condition and in proper tune according to manufacturer's specifications and during smog season (May through October) by not allowing construction equipment to be left idling for long periods. 8. All on-site vehicles should be limited to a speed of 15 mph on unpaved roads. 9. Re -vegetate exposed surfaces. This shall be completed as soon as possible to reduce dust emissions. The Dust Suppression Plan shall be submitted to the County of Butte for review and approval prior to issuance of a grading permit. 10. Soil stockpiled for more than two days shall be covered, kept moist, or treated with .soil binders to prevent dust generation. 11. Burning of vegetative material may be undertaken only after obtaining a valid burn permit issued by the BCAQMD (Rule 300 Open Burning Requirements) and in compliance with the conditions specified on the permit. _ 12. Other measures as determined appropriate by the Butte County Air Quality Management District and Department of Public Works to reduce dust. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 4 The use, storage, and disposal of chemicals associated with uses occurring within the project boundaries shall be applied pursuant to manufacturer's instructions, subject to all applicable laws, regulations, and permits. 9. Environmental Setting: The property is situated approximately 11 miles north of the City of Oroville, east of State Route 70 (SR 70) in the foothills of the Sierra Nevada's on a ridgeline between Rich Gulch and an unnamed intermittent tributary to Lake Oroville, in the southeast portion of Butte County, California. The property can be accessed from SR 70 via Rich Gulch Road and Lower Gulch Road. The property is located on the east side of Lower Gulch Road approximately 0.25 miles south of the Rich Gulch Road intersection on the east side of a ridgeline that runs north/south. From this ridgeline, the property slopes about 5-35 percent to the east. The property ranges in elevation from approximately 1,150 to 1,275 feet. The property drains to the east into Rich Gulch, which flows into Lake Oroville near the confluence of the West Branch and the North Fork of the Feather River. Currently, there is a residential mobile home and domestic water well located on the property. Grading and clearing activities are described in more detail in the Project Description. The project area is comprised of blue oak -foothill pine woodlands that includes both conifer and hardwood tree species. Common associates in blue oak -foothill pine woodlands are foothill pines and blue oaks, occuring at slightly higher elevations than blue oak woodland. Other representative tree species include interior live oak, black oak, and California buckeye. The understory of blue oak - foothill pine woodlands in Butte County contains several shrub species clumped together and interspersed with patches of annual grassland. Dominant shrub species include manzanita, ceanothus, redberry, California coffeeberry, poison oak, blue elderberry, gooseberry, silver lupine, and western redbud (GP EIR, pg 4.4-12). Vegetation in- the area where the leveling activities occurred primarily consisted of woody shrubs, canyon live oak, and conifer tree species. While grading activities avoided the thickest stands of vegetation located on the property, an unknown quantity of various plant species (including trees and shrubs) were removed during grading activities. The area in which grading took place encompasses 0.44 acres of a 10±acre parcel. 10. Surrounding Land Uses: Surrounding parcels vary in size from approximately 10 to 40 acres. Properties within the project vicinity are zoned Foothill Residential with approximately10, 20 and 40 -acre minimum parcel size, and Agriculture 160 -acre minimum parcel size. Surrounding land uses include Lake Croville Recreation Area, Public Lands, and single-family residences. The nearest residence from grading activities is located approximately 300 feet to the north, off Lower Gulch Road. Lake Oroville is located approximately 0.75 miles to the south of the site.

Aesthetics Setting General Plan Figures COS -7, COS -8, and COS -9 depict identified scenic resources in Butte County. Significant scenic resources identified by the General plan are displayed in General Plan Figure COS -7 and are comprised of land-based resources (Butte Creek Canyon, Sacramento River National Wildlife Refuge, Table Mountain, and Feather Falls Scenic Area) and water-based resources (Philbrook Reservoir, Lake Oroville, Thermalito Afterbay, and Lake Wyandotte). Although there are no officially -designated State Scenic Highways in the County, State Route 70 (SR70) north of the inter -section with State Route 149 (SR149) is included in the California Scenic Highway Program and is considered an eligible State Scenic Highway. SR70 through the Feather River Canyon and a portion of State Route 32 (SR32) north of Forest Ranch are recognized as County Scenic Highways. A Scenic Highway Overlay Zone is applied to an area extended 350 linear feet from the centerline of scenic routes identified in COS -9, including portions of SR 32 north of Chico, Portions of SR70 north of the SR149 intersection, the Skyway, southern portions of SR191 and Pentz Road, portions of SR162 along Lake Oroville, and portions of Forbestown Road and Lumpkin Road. Discussion a) Less Than Significant A scenic vista is defined as viewpoint that provides expansive'views of a highly valued landscape for the benefit of the general public. The property is located on the foothill slopes of the Sierra Nevada Mountains and consists of a blue oak -foothill pine woodland habitat community, which is dominated by an understory of mixed chaparral composed of common manzanita, whiteleaf Manzanita, and scrub oak, with associated species such as toyon, California buckeye, and poison oak. The total parcel encompasses 10.1 acres, however, for the purpose of the Grading Permit, the total area affected,by. grading, leveling and terracing activities is approximately 0.44 acres.

Setting General Plan Figures COS -7, COS -8, and COS -9 depict identified scenic resources in Butte County. Significant scenic resources identified by the General plan are displayed in General Plan Figure COS -7 and are comprised of land-based resources (Butte Creek Canyon, Sacramento River National Wildlife Refuge, Table Mountain, and Feather Falls Scenic Area) and water-based resources (Philbrook Reservoir, Lake Oroville, Thermalito Afterbay, and Lake Wyandotte).

The total parcel encompasses 10.1 acres, however, for the purpose of the Grading Permit, the total area affected,by. grading, leveling and terracing activities is approximately 0.44 acres. The initial grading, APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 12 leveling, and terracing operation involved minimal removal of trees and brush and disturbance to the soil (refer to Section 4, Biological Resources). The remaining 9.6 -acre portion of the property has not been affected by grading and terracing (with the exception of a permitted trailer residence and associated access road) activities and no additional grading activity is proposed. The perimeter of the site screens adjacent parcels with native vegetation. There are no water features, unique geologic features, which are considered local scenic ,resources. the graded area cannot be viewed from adjacent roadways or parcels; therefore, grading activities will have a less than significant impact on a scenic vista and would not substantially degrade the visual character of the site and surroundings. , b) No Impact The project site is located approximately 0.65 miles east of SR 70. Although there are no officially designated State Scenic Highways in Butte County, SR 70 north of the intersection with Highway 149 is a county designated scenic highway and is considered an eligible State scenic highway. A Scenic Highway Overlay Zone extends 350 linear feet from the centerline of scenic routes (GP EIR, pg 4.1-7). Although the property is accessed from SR 70 via Rich Gulch Road, it is 0.65 miles from SR 70 and is outside this Zone and is not visible from SR 70. Therefore, grading activities would have no impact to scenic resources within a designated County scenic highway. C) Less Than Significant Refer to the discussion under Item a) above. d) No Impact The proposed project would not result in the establishment of a new light source (i.e. residential lighting, streetlights and so forth). Grading activities would not result in a new significant source of lighting, nor would it affect nighttime views in the area. 2.

I I I I Setting The Farmland Mapping and Monitoring Program (FMMP) of the California Resources Agency issued an Important Farmlands MaI2 for Butte Coun-ty identifying Prime Farmland, Farmland of Statewide Importance, Unique Farmland, and Grazing land. The map is maintained by the State of CA Department of Conservation and designates the subject property as Other Land. Other Land denotes "land not included in any other mapping category, common examples include low density rural developments, brush, timber, wetland, and riparian areas not suitable for livestock grazing, confined livestock, poultry, or aquaculture facilities, strip mines, borrow pits, and water bodies smaller than 40 acres. Vacant and nonagricultural land surrounded on all sides by urban development, and greater than 40, acres is mapped as other land. Soils on the site are identified by the Natural Resource Conservation Service (NRCS) as Oroshore- Mounthrope-Dunstone gravelly clay loam, 1.5 to 30 percent slope. The site does not contain prime agricultural soils. Discussion a,b) No Impact The proposed project is the grading and leveling of land to accommodate the installation of an organic garden or similar use. It is anticipated that horticultural activities will occur on site in the future. The Important Farmlands Map for Butte County does not identify important farmlands on the project site; rather, it identifies the site as 'Other Land! Additionally, the soils on site are not prime soils, and the site is designated for residential development. A review of the Butte County General Plan 2030 Land Use Map identifies the property as being located within an area designated as Foothill Residential (FR -20), 20 -acre minimum parcel size. Foothill residential zoning designation allows single-family dwellings at rural densities of 1 to 40 acres per dwelling unit, depending on the zoning. The site is not important farmland and does not occur on prime agricultural soils; therefore, grading activities would not convert Farmland (Prime, Unique or of Statewide Importance) pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency to a non-agricultural use. c,d) Less Than Significant. As stated under Item a) above, the site is designated as Foothill Residential and a zoning designation as FR -20. The project would not result in the rezoning of forest land or timberland zoned for Timberland production. The project involves the grading and terracing of a 0.44 -acre are of a 10 -acre site within montane hardwood -conifer and mixed chaparral habitat. Grading would not result in the loss of forest land or conversion of forest land to non -forest use or non-agricultural use. Refer to Section 4, Biological Resources, Item b) further below for a description of vegetation communities in the project area and on the project site. e) No Impact As stated under Item a) above, grading activities would not convert Farmland (Prime, Unique or of Statewide Importance) pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency. Grading activities will not affect agriculturally -designated property to the south. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 14 11. Burning of vegetative material may be undertaken only after obtaining a valid burn permit issued by the BCAQMD (Rule 300 Open Burning Requirements) and in compliance with the conditions specified on the permit. I - 12. Other measures as determined appropriate by the Butte County Air Quality Management District and Department of Public Works to reduce dust. Although grading on the site likely resulted in some level of grading -related dust and particulate matter emissions, no further construction or construction vehicle related emissions is anticipated. Should additional grading activities be necessary as part of needed erosion control, per the grading permit, Conservation Measure CM#3 would apply. Grading activities do not conflict with or obstruct implementation of the applicable air quality plan; therefore, there is a less than significant impact. b, c) Less Than Significant The BCAQMD uses general screening criteria to determine the type and scope of projects requiring an air quality assessment and/or mitigation. These criteria are based on project size and are focused primarily on the indirect emissions (i.e., motor vehicles) associated with residential, commercial and industrial development. Due to the relatively limited scale of grading required, 0.44 acres, equipment related emissions would not exceed District emission thresholds. Therefore, grading will not violate State or Federal air'quality standards or contribute to an existing air quality violation in the basin as only minor amounts of material has been, or will be moved. Therefore, grading would not result in locally elevated levels of regulated air emissions in close proximity to sensitive receptors. d) No Impact Sensitive populations (i.e., children, senior citizens and acutely or chronically ill people) are more susceptible to the effects of air pollution than are the general population. Land uses considered sensitive receptors typically include residences, schools, playgrounds, childcare centers, hospitals, convalescent homes, and retirement homes. The surrounding area is designed as FR -20, which means that adjacent parcel sizes are twenty acres or greater in size. The nearest resident or structure is approximately 500 -feet north of grading activities. In addition, grading activities are temporary, and a Dust Suppression Conservation Measures (CM#3) would be implemented as part of future grading work, thereby minimizing dust emissions. There are no other sensitive receptors in proximity to the project site. e) No Impact Grading activities would not result in the creation of objectionable odors affecting a substantial number of people. 4.

Any fencing of the graded portion of the site would not pose a significant impediment to migrating deer populations within the area. Therefore, there is a less than significant impact on the movement of native wildlife species. e) No Impact The project site is located in the transitional ecotone from the valley foothill hardwood -conifer, mixed chaparral and montane hardwood -conifer communities, is common locally and regionally throughout California, . Grading and terracing activities affected a 0.44 -acre portion of the property. The project would not conflict with any Butte County tree policy or ordinance adopted for the long-term preservation of oak woodlands, including the Butte County Oak Woodlands Management Plan. No Impact. The project site is not located in an area identified as having an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or any other approved local, regional, or state habitat conservation plans. The Butte Regional Conservation Plan (BRCP) is scheduled for final approval in late 2014. Based on available information, the project site is not located in an area of Butte County that will be regulated by the BRCP. Therefore, the project would not conflict with the provisions of an adopted Habitat Conservation Plan. g) No Impact Refer to discussion under Item a) above. The project is not located in an. area identified as critical habitat, nor is the project in the recovery area for unique, rare, threatened, or endangered species of animals. h) Less Than Significant Impact. Refer to the discussion under Item a) and Item b) above. The graded area comprises 0.44 acres within a 10.1 -acre site, the remainder of the site is undisturbed and provides habitat for a variety of species. The site. consists of blue oak - foothill pine woodland habitat, which occurs throughout California and is not considered a sensitive natural community, nor is the area a designated critical habitat or recovery area for any listed rare, threatened and endangered species. Animals typically associated with this habitat type are common species, the diversity of which would not be significantly impacted by the removal of a small portion of their associated habitat. i) Less Than Significant Impact. Refer to the discussion under Item h) above. Rich Gulch, a jurisdictional intermittent stream, occurs 600 -feet east of grading activities. However, project grading activities were not conducted within the vicinity of the drainage. Fish and wildlife that may use the site and drainage are still able to forage, breed, roost and nest within the surrounding area. j) Less Than Significant Impact Refer to the discussion under Item d) above. k) Less Than Significant Impact Refer to the discussion under Item d) above. No temporary lighting is proposed. In addition, although site activities may include temporary noise associated with human activity, the proposed project would not result in the establishment of new permanent noise or light sources. Temporary noise is not anticipated to be at a level that would substantially alter the normal activities of wildlife, such as with a residential subdivision, commercial land use development, or major roadway. Furthermore, the proposed project is consistent with the General Plan Land Use and Zoning designations. Project activities would not increase human presence more than what would be permitted from other allowed uses within this zone. APN OSB -650-016 Grading Permit December2014 Initial Study/Mitigated Negative Declaration Page 24 Mitigation: Mitigation Measure MMI (Oak Woodlands) Prior to final acceptance of the grading permit, an Oak Tree Mitigation Plan prepared by a certified arborist, registered professional forester, botanist or landscape architect shall be submitted for review and approval by the Director of Development Services or his/her designee that includes: 1)A survey showing the location of oak trees 5 inches or more in diameter at breast height, as defined by PRC §21083.4(a); 2)The removal of all oak trees 5 inches or more in diameter at breast height shall be mitigated. It shall be mitigated by one or more of the following: replanting and maintaining oak trees, establishing conservation easements, contributing funds for off-site oak woodlands conservation, and/or other mitigation measures developed by Butte County. Replanting oak trees cannot account for more than one-half of the mitigation. Replanted oak trees shall be maintained for a period of seven years after they are planted. If any of the replanted oak trees die or become diseased, they shall be replaced and maintained for seven years after the new oak trees are planted; 3)A replanting schedule and diagram for trees removed or encroached upon by permit activities consistent with PRC §21083.4(b)(2), applicable mitigation measures, and Butte County Ordinance, if any, shall be submitted to and approved by the Director of Development Services or his/her designee. Replanted trees shall be planted in areas deemed appropriate by the Plan, considering future lot development, interference with foundations, fencing, roadways, driveways, and utilities. Trees planted shall be protected from livestock and other animals; 4)Oak Tree protection measures for trees to be retained within the project site shall be included in construction specifications. Each oak tree to be preserved shall be surrounded by a tree zone identified by the drip line of the tree. An orange plastic fence or other suitable type of fence shall be used to identify the tree zone during construction activities. No vegetation removal, soil disturbance, or other development activities shall occur within the tree zone in order to protect root systems and minimize compaction of the soil, unless authorized by Oak Tree Mitigation Plan; and S)Conservation easements or funds for off-site oak woodlands conservation shall be proposed to and approved by the Director of Development Services or his/her designee." Plan Requirements: No vegetation removal, grading, road construction, or other earthwork shall be permitted until the Oak Tree Mitigation Plan is submitted and approved. Timing: Requirements of the condition shall be satisfied prior final acceptance of the grading permit, and prior to any development activity or the issuance of any grading, building, septic, or well permit, or the approval of any improvement plans on the parcels. Monitoring: The Butte County Department of Development Services and Department of Public Works shall ensure thatthis mitigation is complied with prior to final acceptance of the grading permit.

The site and the immediate surrounding vicinity are not designated as archaeological or historically sensitive areas. In addition, there are no known cultural resources located on the property that are examples of the major periods of California history or prehistory. The existing 0.44 -acre of a 10.1 -acre project site has been disturbed by grading activities and unknown historic resources have not been discovered. Further activities on the site would consist of stabilizing the site for water quality protection and erosion control. Additional grading activities are not anticipated. Site stabilization measures would consist of the BMPs, as described in Section 9, Item a) Hydrology and Water Quality. C) No Impact. Due to the project site's location, lack of outcroppings, or unique geologic features on the property and that existing disturbance has not revealed any sub -surface resources, continued site stabilization activities are not likely to directly or indirectly destroy sub -surface resources as additional grading is not anticipated. d) No Impact There are no known grave sites within the project limits. Therefore, the disturbance of human remains is not anticipated. However, in the unlikely event that human remains are encountered, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. The County Coroner must be notified of any human remains find immediately.

The following is a -list of measures that will be implemented, as part of the Erosion and Sediment Control Plan: 1. If BMP's are damaged in a storm, repairs should be completed within 72 hours. Care should be exercised to minimize damage and protected areas while making repairs. 2. If BMP's have failed, or are ineffective, notify the owner/contractor to modify the BMP or specify an alternative. The modification or alternative should be installed within 72 hours of approval 3. If seeds fail to germinate, or they germinate and die, the area must be re -seeded, fertilized, and mulched within the planting season. Not less than half the original application rate should be applied. 4. Straw wattles shall have a minimum functional longevity of 1 year and shall be replaced annually if required beyond 1 year. APN 058-650-016 Grading Permit December2014 Initial Study/Mitigated Negative Declaration Page 29 5. Upon permanent stabilization, and approval of the engineer, temporary BMPs may be removed if no longer needed. b) Less Than Significant Impact The project lies within an area that has a high erosion hazard potential. (GP EIR, Figure 4.6-4) As stated earlier, stabilization of exposed soil within the graded area will be accomplished through the use of hydroseed (containing mulch, seed, and tacifier) as well as aggregate base. Additionally, the ECP requires notifying the engineer/QSD should any of the BMP's fail or become ineffective. Any areas that are not effectively stabilized will be addressed accordingly by replacing BMPs. The implementation of effective stabilization techniques will yield no substantial soil erosion or loss of topsoil. C) Less Than Significant Impact While the project is located in an area identified as having a 'high' landslide potential, it is not located on a geologic unit or soil that is considered unstable or that would become unstable as a result of the project. Therefore, the potential for on-site or off-site landslide, lateral spreading, or collapse is less than significant. According to the Natural Resources Conservation Service, the soil type within the project area is entirely within Map Unit 671 Oroshore-mounthrope-Dunstone soils (NRCS 2014). This Unit is composed of gravelly coarse and clay loams, similar soils, and paralithic bedrock at approximately 40-60 inches, which are not prone to liquefaction. Additionally, there have been no documented incidents of subsidence in Butte County and the only areas at risk for subsidence are in the valley region (GP EIR, pg 4.6-12), not the foothills where the project is located. d) Less Than Significant Impact. . The project is located in an area with low expansive soil potential (GP EIR, Figure 4.6-3). Expansive soils are generally found in basin deposits in the low-lying portions of the county near the Sacramento and Feather Rivers as well as localized areas elsewhere in the county (GP EIR, pg 4.6-12). The project site is not located in expansive soil areas. e) No Impact. The project will not use or install septic tanks or alternative wastewater disposal systems. 7. Greenhouse Gas Emissions Setting The earth's atmosphere naturally contains a number of gases, including (but not limited to) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), which are collectively referred to as greenhouse gases (GHGs).

Setting The property is located in an area designated by CAL FIRE as a Very High Fire Hazard Severity Zone (GP EIR, Figure 4.7-1). The project involves the grading and leveling of land and the removal of vegetation from the graded portion of the site to a 'slash pile' near the entrance to the site. The applicant has agreed to use any chemicals according to the manufacturer's specifications, as reflected in CM#4 below. Conservation Measures CM #4 (Use of ChemicaW The use, storage, and disposal of chemicals used within the project boundaries shall be applied pursuant to manufactureijs instructions, subject to all applicable laws, regulations, and permits. Discussion a) No Impact The proposed project would not involve the routine transport, use, or disposal of hazardous materials, and would not result in such impact. b) No Impact. The proposed grading activities and site stabilization measures are not anticipated to result in a release of hazardous materials into the environment. C) No Impact Grading and clearing activities do not involve any emission or handling of any hazardous materials, substances, or waste within one-quarter mile of an existing school. No existing or proposed school facilities are located within a one-quarter mile radius of the project site. d) No Impact. The property is not included on a list of sites containing hazardous materials, and would not result in a significant hazard to the public or to the environment. The project site is not included on the Cortese -Knox list compiled pursuant to Government Code Section 65962.5. e) No Impact, The proposed project site is not located within an airport land use plan or within two miles of a public airport and the project would not result in permanent structures that expose people to a safety hazard. APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 33 No Impact The proposed project site is not located within the ' vicinity of a private airstrip and the project would not result in permanent structures that expose people to a safety hazard. g) No Impact The proposed project does not include any actions within the roadway that would physically interfere with any emergency response or emergency evacuation plans. The project would not result in an increase in traffic, and thus would not reduce the current level of service of the area road network. h) Less than Significant with Mitigation.. The property is located in an area designated by CAL FIRE as a Very High Fire Hazard Severity Zone (GP EIR, Figure 4.7-1). The project involves the grading and leveling of land and the removal of vegetation from the graded portion of the site to a 'slash pile' near the entrance to the site. Comprised of dead and dry vegetation, the slash pile provides fuel for wildIfires that may occur near the project site. Decomposition and ignition of the slash pile can also occur over time. For these reasons, the removed vegetation associated with grading activities could expose people or structures to a signiflcant risk of wildland fires. Mitigation Measure MM2 requires that vegetation cleared during grading activities be handled appropriately by one of three methods: removing to a permitted green waste facility, chipping and distributing the materials on site, or burning the materials consistent with a valid burn permit from the BCAQMD. With the removal of cleared vegetation, any fire hazard associated with grading permit activities will be less than significant. Mitigation: A note on the final grading plan states: "All vegetation cleared during grading activities shall be removed from the project site by one of three methods: removing vegetation to a permitted green waste facility, chipping and distributing the materials on site, or burning cleared vegetation consistent with a valid burn permit from the Butte County Air Quality Management district (BCAQMD)." Plan Requirements: Remove fire danger from cleared (downed, dead) vegetation. Timing: Prior to the Public Works Director singing off the final Grading Permit. Monitoring: Public Works Land Development will ensure cleared vegetation is removed prior to final grading approval. 9.

The project will not yield an increase in storm water runoff that would require the use or construction of storm water drainage facilities. As addressed in Item a) above, the Grading Plan and ECP will meet water quality standards and not result in polluted runoff. Less Than Significant Impact Refer to Item a) above. The ultimate goal of an Erosion Control Maintenance plan is to prevent degradation of water quality through the prevention of sediment and pollutant runoff. The ECP is project specific and designed to minimize erosion, thereby protecting water quality. g -i) No Impact The proposed project, which is grading and clearing activities, is not located within a 100 -year flood hazard area. Project activities would not result in placing housing in a 100 -year flood hazard area, nor would activities impede or redirect flood flows. The project would not expose people or structures to significant risk of loss, injury or death involving flooding as a result of levee or dam failure. D No Impact There are no anticipated impacts to the proposed project from seiche, tsunami, or mudflow, as no topographical features of water bodies capable of producing such events occur within the project site vicinity. 10. Land Use and Planning Discussion a) No Impact Grading activities have been conducted on a 0.44 -acre site within a 10.1 -acre property. The site is located in the foothills of the Sierra Nevada Mountains and is rural in nature, with no surrounding neighborhoods. Therefore, the project will not have an impact on the physical arrangement of an established community. b) No Impact The proposed project is consistent with the General Plan Land Use designation of Foothill Residential and the FR -20 (Foothill Residential, 20 -acre minimum parcel size) zoning designation. The project would neither propose a change in zoning, nor conflict with APN 058-650-016 Grading Permit December 2014 Initial Studyllditigated Negative Declaration Page 38 Less Than Would the project: Potentially Significant LessThan No Significant With Significant Impact Mitigation a) Physically divide an established community?

Discussion a) No Impact Grading activities have been conducted on a 0.44 -acre site within a 10.1 -acre property. The site is located in the foothills of the Sierra Nevada Mountains and is rural in nature, with no surrounding neighborhoods. Therefore, the project will not have an impact on the physical arrangement of an established community. b) No Impact The proposed project is consistent with the General Plan Land Use designation of Foothill Residential and the FR -20 (Foothill Residential, 20 -acre minimum parcel size) zoning designation. The project would neither propose a change in zoning, nor conflict with APN 058-650-016 Grading Permit December 2014 Initial Studyllditigated Negative Declaration Page 38 Discussion a) Less Than Significant The Butte County Board of Supervisors passed Ordinance #4053, Noise Control on March 26, 2013. The Ordinance became effective on April 25, 2013. The Ordinance states: Noise sources associated with construction, repair, remodeling, demolition, paving or grading of any real property or public works project located within 1,000 feet of residential uses, provided said activities do not take place between thefollowing hours: • Sunset to sunrise on weekdays and non -holidays; • Friday commencing at 6:00 p.m. through and including 8:00 a.m. on Saturday, as well as not before 8:00 a.m. on holidays; • Saturday commencing at 6:00 p.m. through and including 10:00 a.m. on Sunday; and, • Sunday after the hour of 6:00 p.m. Provided, however, when an unforeseen or unavoidable condition occurs during a construction project and the nature of the project necessitates that work in process be continued until a specific phase is completed, the contractor or owner shall be allowed to continue work into the hours delineated above and to operate machinery and equipment necessary to complete the specific work in progress until that specific work can be brought to conclusion under conditions which will not jeopardize inspection acceptance or create unduefinancial hardshipsfor the contractor or owner. Additional grading activities are not anticipated. However, if grading were necessary, the implementation of the provisions of the Noise Ordinance would reduce any temporary and periodic increase in noise levels to less than significant levels. b) Less Than Significant The project encompasses grading and clearing on 0.44 acres, most of which has been conducted. Although additional grading activities are not anticipated, any activities suchas site stabilization would be temporary, occur during less sensitive daytime hours, and short in duration. As a result, any potential impacts from grading -related groundborne vibrations or noises would be less than significant. C) No Impact The proposed project does not involve uses or activities that would result in a substantial permanent increase in ambient noise levels in the project vicinity. Although additional grading activities are not anticipated, noise associated with any additional activities would be temporary. d) Less Than Significant The property is located in a rural, area with generally low noise levels and is not subject to any significant continuous noise. The nearest residence is approximately 500 ft of project activities. Any additional grading activities on the site would temporarily generate an increase in noise levels on and adjacent to the site. However, noise levels would be temporary and would not be in excess of local standards. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 41 e, No Impact. The proposed project is not located within an airport land use plan or within two miles of a public airport, public use airport, or private airstrip. As such, the project would not expose people residing or working in the project area to excessive n6ise levels. 13. Population and Housing Discussion a) Less Than Significant No significant population growth associated with the proposed project is expected. Any employment generated by grading activities would be temporary and drawn from the local work force, and would not create a permanent population growth to the area. b, c) No Impact.

Project Location: Figure 1 Location Map APN 058-650-016 located at 121Lower Gulch Road in Yankee Hill, Butte County, California. Affected area is approximately 0.44 acres on a 10+/ --acre parcel. Latitude: 39.6854N, Longitude: -121.5265W 6. General Plan Designation: Foothill Residential 7. Zoning: FR -20 (Foothill Residential, 20 -acre minimum parcel size) 8. Project Description: The applicant requests approval of a Grading Permit pursuant to Butte County Code Chapter 13, Article I for a grading operation that disturbed 0.44 acres of a 10+ -acre property for the purposes of leveling land for the installation of an organic garden or similar use. Grading activities were conducted over a one-week period. in April 2013 using a small tractor. Disturbance to the site included the leveling and terracing of approximately 0.44 acres of land within an unimproved portion of the residential property. There are no additional grading, clearing, or vegetation removal activities proposed as part of the project. However, the owner is required to maintain BMP's which may involve additional minor soil disturbance over time. Vegetation in the area where the leveling activities occurred consisted primarily of woody shrubs, canyon live oak, and conifer tree species. While grading activities avoided the thickest stands of vegetation located on the property, approximately 13 oak trees and 1 pine tree were removed; see Figure 2, Grading and Erosion Control Plan. The Grading Permit request includes the following estimates of grading, cut, and fill. 1. Grading of the land; the extent of grading, clearing, and terracing activities comprise approximately 0.44 acres. The applicant has leveled the existing land cutting approximately 250 cubic yards and filling approximately 250 cubic yards.

I I I Setting The Farmland Mapping and Monitoring Program (FMMP) of the California Resources Agency issued an Important Farmlands MaI2 for Butte County identifying Prime Farmland, Farmland of Statewide Importance, Unique Farmland, and Grazing land. The map is maintained by the State of CA Department of Conservation and designates the subject property as Other Land. Other Land denotes "land not included in any other mapping category, common examples include low density rural developments, brush, timber, wetland, and riparian areas not suitable for livestock grazing, confined livestock poultry, or aquaculture facilities, strip mines, borrow pits, and water bodies smaller than 40 acres. Vacant and nonagricultural land surrounded on all sides by urban development, and greater than 40 acres is mapped as other land. Soils on the site are identified by the Natural Resource Conservation Service (NRCS) as Oroshore- Mounthrope-Dunstone gravelly clay loam,,15 to 30 percent slope. The site does not contain prime agricultural soils. Discussion a,b) No Impact The proposed project is the grading and leveling of land to accommodate the installation of an organic garden or similar use. It is anticipated that horticultural activities will occur on site in the future. The Important Farmlands Map for Butte County does not identify important farmlands on the project site; rather, it identifies the site as 'Other Land.' Additionally, the soils on site are not prime soils, and the site is designated for residential development. A review of the Butte County General Plan 2030 Land Use Map identifies the property as being located within an area designated as Foothill Residential (1711-20), 20 -acre minimum parcel size. Foothill residential zoning designation allows single-family dwellings at rural densities of 1 to 40 acres per dwelling unit, depending on the zoning. The site is not important farmland and does not occur on prime agricultural soils; therefore, grading activities would not convert Farmland (Prime, Unique or of Statewide Importance) pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency to a non-agricultural use. c,d) Less Than Significant. As stated under Item a) above, the site is designated as Foothill Residential and a zoning designation as FR -20. The project would not result in the rezoning of forest land or timberland zoned for Timberland production. The project involves the grading and terracing of a 0.44 -acre are of a 10 -acre site within montane hardwood -conifer and mixed chaparral habitat. Grading would not result in the loss of forest land or conversion of,forest land to non -forest use or non-agricultural use. Refer to Section 4, Biological Resources, Item b) further below for a description of vegetation communities in, the project area and on the project site. e) No Impact As stated ' under Item a) above, grading activities would not convert Farmland (Prime, Unique or of Statewide Importance) pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency. Grading activities will not affect agriculturally -designated property to the south. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 14 t 3. Air Quality Discussion a) Less Than Significant The property is located in the Sacramento Valley Air Basin (SVAB), which is divided into two planning sections. Butte County belongs to the Northern Sacramento Valley Air Basin (NSVAB). The NSVAB has been categorized as "moderately" non -attainment for ozone and particulate matter. The County is under the jurisdiction of the Butte County Air Quality Management District (BCAQMD), a regional agency responsible for regulating sources of air pollution in Butte County. The BCAQMD is responsible for the preparation of plans for the attainment and maintenance of Ambient Air Quality Standards (AAQS), adoption and enforcement of rules and regulations for sources of air pollution, and issuance of permits for stationary sources of air pollution. The Air Pollution Control Districts and Air Quality Management Districts (Districts) for the'. counties located in the northern portion of the Sacramento Valley together compromise the Northern Sacramento Valley Planning Area (NSVPA). The NSVPA Districts have committed to jointly prepare and adopt a uniform air quality attainment plan for the purpose of achieving and maintaining healthful air quality throughout the air basin. This triennial update of the NSVPA Air Quality Attainment Plan (Plan) addresses the progress made in implementing the 2009 Plan and proposes modifications to the strategies necessary to attain the California ambient air quality standard for the 8 -hour ozone at the earliest practicable date. The 2012 Plan identifies those portions of the NSVPA designated as "non - attainment" for the State ambient air quality standards and discusses the health effects related to the various air pollutants. The Plan identifies the air pollution problems which are to be cooperatively addressed on as many fronts as possible in order to make the region .7 APN 058-650-016 Grading Permit December2014 Initial Study/Mitigated Negative Declaration Page 15 Less Than would the project: Potentially Significant Less Than No Significant with Significant Impact Mitigation a) Conflict with or obstruct implementation of the applicable air quality plan?

Like the 2006 and 2009 Plans, the 2012 Plan focuses on the adoption and implementation of control measures for stationary sources, area wide sources, and indirect sources, and addresses public education and information programs (NSVPA Air Quality Attainment Plan, pg. 3). The project consists of grading and terracing of 0.44 acres of land. Conservation Measure CM#3 incorporates dust suppression measures to reduce dust and particulate matter associated with future grading activities. These measures are consistent with the BCAQMD Standard Mitigation Measures for the reduction of dust and particulate matter as per Section 6.3 of the BCAQMD Handbook. These measures include: Conservation Measure CM#3 (Dust Suppressimil The project also includes dust suppression measures to reduce dust and particulate matter associated with grading activities. These include: 1. Conduct daily cleanup. This practice shall include removal of mud and dust carried onto street surfaces by construction vehicles. During clearing grading, earth -moving, excavation, or transportation of cut or fill materials, water trucks or sprinkler systems are to be used to prevent dust from leaving the site and to create a crust after each day's activities cease. 2. Cover haul trucks with tarpaulins or other effective covers at all times, except when loading or unloading materials. 3. Water all exposed earth surfaces. This practice shall be conducted at a minimum in the late morning and at the end of the day.

The California Natural Diversity Database (CNDDB) identifies sensitive natural communities (SNC) based on classifications created by Holland, R.F. (1986), which includes those communities that, if eliminated or substantially degraded, would sustain a significant adverse impact as defined under CEQA. According to the General Plan EIR, Figure 4.4-1, Vegetative Communities and Wildlife Areas, the project area is designated as conifer and oak woodland, which are regionally abundant common natural communities occurring throughout the eastern portion of the County. The site is located in the transitional ecotone from the valley foothill hardwood -conifer, mixed chaparral and montane hardwood -conifer communities. A majority of the site is covered in blue oak -foothill pine habitat, including interior live oak, black oak, and several shrub species such as manzanita, ceanothus, redberry and California coffeeberry etc. Other portions of the site consist of natural open areas, the 0.44 -acre graded area, and the mobile home site. It is estimated that during grading and clearing activities approximately 14 trees were removed, including a pine and 13 oaks of unknown oak subspecies.. Public Resources Code section 21083.4 specifies that "a county shall determine whether a project within its jurisdiction may result in the conversion of oak woodlands that will have a significant effect on the environment." If a county determines there may be a significant effect to oak woodlands, the county must require one or more mitigation alternatives to mitigate the significant effect of the conversion. Butte County has not adopted a criteria for assessing oak woodland loss. An Oak Woodland Impact Decision Matrix was published in 2008 by the UC Integrated Hardwood Range Management Program as an analytical approach to oak woodland impact analysis. An impact decision matrix (page 12) can be used to describe the significance of oak woodland loss. Since the project site was disturbed prior to permit, the quality of the oaks cut down during grading activities must be inferred based on the surrounding oak woodland. a "moderately degraded woodland" (given the location of adjacent roadways, the grading activities, and the surrounding parcels and land uses). Page 8 of the Matrix identifies criteria that could be considered to determine significance, including the net loss of approximately 0.44 acres of a 10 -acre site and road building activities that facilitate future home -site construction. To offset this impact, Mitigation Measure (MM1) is provided below to replace oak woodland loss consistent with the Public Resources Code. C) No Impact A review of aerial imagery and site photos indicates no jurisdictional waters are present within the property boundary. The closest jurisdictional drainage, Rich Gulch, is located approximately 0.75 miles north of Lake Oroville. Rich Gulch is approximately 600 - feet east of the project site. Although no additional grading activities are anticipated, the applicant will be required to implement an Erosion Control Maintenance Plan (ECP) to minimize erosion and sedimentation as a result of grading and thereby minimize water quality impacts off-site. By implementing an ECP, there will be no impacts to waters of the U.S. and wetlands located offsite. d) Less Than Significant Impact The project area is located within an area designated by the General Plan as Critical Deer Herd Range (GP EIR, Figure 4.4-4, Migratory Deer Herd Areas). With the exception of a small section of fencing along the western property line at the road, there are no other barriers to interfere with the movement of wildlife through the project site. The fencing along the western property line at the road does not pose a significant impediment to migrating deer populations within the area. If the graded area is fenced as part of future uses, it will account for a 0.44 -acre portion of a 10.1 -acre parcel, APN 058-650-016 Grading Permit December2014 Initial StudylMitigated Negative Declaration Page 23 Mitigation: Mitigation Measure MMI (Oak Woodlands) Prior to final acceptance of the grading permit, an Oak Tree Mitigation Plan prepared by a certified arborist, registered professional forester, botanist or landscape architect shall be submitted for review and approval by the Director of Development Services or his/her designee that includes: 1)A survey showing the location of oak trees 5 inches or more in diameter at breast height, as defined by PRC §21083.4(a); 2)The removal of all oak trees 5 inches or more in diameter at breast height shall be mitigated. It shall be mitigated by one or more of the following: replanting and maintaining oak trees, establishing conservation easements, contributing funds for off-site oak woodlands conservation, and/or other mitigation measures developed by Butte County. Replanting oak trees cannot account for more than one-half of the mitigation. Replanted oak trees shall be maintained for a period of seven years after they are planted. If any of the replanted oak trees die or become diseased, they shall be replaced and maintained for seven years after the new oak trees are planted; 3)A replanting schedule and diagram for trees removed or encroached upon by permit activities consistent with PRC §21083.4(b)(2), applicable mitigation measures, and Butte County Ordinance, if any, shall be submitted to and approved by the Director of Development Services or his/her designee. Replanted trees shall be planted in areas deemed appropriate by the Plan, considering future lot development, interference with foundations, fencing, roadways, driveways, and utilities. Trees planted shall be protected from livestock and other animals; 4)Oak Tree protection measures for trees to be retained within the project site shall be included in construction specifications. Each oak tree to be preserved shall be surrounded by a tree zone identified by the drip line of the tree. An orange plastic fence or other suitable type of fence shall be used to identify the tree zone during construction activities.

Cultural Resources Discussion a, b) No Impact The site and the immediate surrounding vicinity are not designated as archaeological or historically sensitive areas. In addition, there are no known cultural resources located on the property that are examples of the major periods of California history or prehistory. The existing 0.44 -acre of a 10.1 -acre project site has been disturbed by grading activities and unknown historic resources have not been discovered. Further activities on the site would consist of stabilizing the site for water quality protection and erosion control. Additional grading activities are not anticipated. Site stabilization measures would consist of the BMPs, as described in Section 9, Item a) Hydrology and Water Quality. c) No Impact Due to the project site's location, lack of outcroppings, or unique geologic features on the property and that existing disturbance has not revealed any sub -surface resources, continued site stabilization activities are not likely to directly or indirectly destroy sub -surface resources as additional grading is not anticipated. d) No Impact There are no known grave sites within the project limits. Therefore, the disturbance of human remains is not anticipated. However, in the unlikely event that human remains are encountered, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. The County Coroner must be notified of any human remains find immediately. If the remains are determined to be prehistoric, the Coroner will notify the Native American Heritage Commission (NAHC), which will determine and notify a Most Likely Descendant (MLD). With the permission of the landowner or his/her authorized representative, the MLD may inspect the site of the discovery, and must complete the inspection within 24 hours of notification by the NAHC.

Any sediment tracked off the property and onto paved roadways shall be swept immediately after each vehicle leaves the site. 7. Haul trucks shall be covered with tarpaulins or other effective covers at all times. 8. If the construction site is to remain inactive longer than 14 days then the site shall be - stabilized by applying "earth guard" or seeded and watered until grass cover is grown. 9. Inspect sediment control devices before each storm to verify they are in proper order. Inspect the sediment control devices after each storm, removing collected sediment and repairing deficiencies. 10. Du ring long periods of rain and high intensity rainfall, BMPs may become clogged. Extreme care should be taken to clean BMPs to reduce fugitive discharge and potential flooding. 11. Applicant may remove temporary BMPs (wattles and silt fencing) once permanent BMPs have been established. 12. Native seed and erosion control matting shall be applied to all disturbed areas that are not subject to heavy wear from construction equipment or other vehicles. Irrigation will be performed by hand watering. Seed and mulch shall be kept moist at all times until germination has occurred. Seed should be in conformance with the California State Seed Law and applied at the following rate: Seed - Melica californica: 10 lbs/acre Fiber - 100% wood fiber- 2,000 lbs/acre Tack - Scilium based "M" binder 120 lbs/acre The project includes an Erosion and Sediment Control Plan (Figure 3), which is part of the Grading Plan. The following is a list of measures that will be implemented, as part of the Erosion and Sediment Control Plan: 1. If BMP's are damaged in a storm, repairs should be completed within 72 hours. Care should be exercised to minimize damage and protected areas while making repairs. 2. If BMP's have failed, or are ineffective, notify the owner/contractor to modify the BMP or specify an alternative. The modification or alternative should be installed within 72 hours of approval 3. If seeds fail to germinate, or they germinate and die, the area must be re -seeded, fertilized, and mulched within the planting season. Not less than half the original application rate should be applied. 4. Straw wattles shall have a minimum functional longevity of 1 year and shall be replaced annually if required beyond 1 year. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 29 S. Upon permanent stabilization, and approval of the engineer, temporary BMPs may be removed if no longer needed. b) Less Than Significant Impact The project lies within an area that has a high erosion hazard potential. (GP EIR, Figure 4.6-4) As stated earlier, stabilization of exposed soil within the graded area will be accomplished through the use of hydroseed (containing mulch, seed, and tacifier) as well as aggregate base. Additionally, the ECP requires notifying the engineer/QSD should any of the BMP's fail or become ineffective. Any areas that are not effectively stabilized will be addressed accordingly by replacing BMPs. The implementation of effective stabilization techniques will yield no substantial soil erosion or loss of topsoil. C) Less Than Significant Impact While the project is located in an area identified as having a 'high' landslide potential, it is not located on a geologic unit or soil that is considered unstable or that would become unstable as a result of the project. Therefore, the potential for on-site or off-site landslide, lateral spreading, or collapse is less than significant. According to the Natural Resources Conservation Service, the soil type within the project area is entirely within Map Unit 671 Oroshore-mounthrope-Dunstone soils (NRCS 2014). This Unit is composed of gravelly coarse and clay loams, similar soils, and paralithic bedrock at approximately 40-60 inches, which are not prone to liquefaction. Additionally, there have been no documented incidents of subsidence in Butte County and the only areas at risk for subsidence are in the valley region (GP EIR, pg 4.6-12), not the foothills where the project is located. d) Less Than Significant Impact . The project is located in an area with low expansive soil potential (GP EIR, Figure 4.6-3). Expansive soils are generally found in basin deposits in the low-lying portions of the county near the Sacramento and Feather Rivers as well as localized areas elsewhere in the county (GP EIR, pg 4.6-12). The project site is not located in expansive soil areas. e) No Impact The project will not use or install septic tanks or alternative wastewater disposal systems. 7. Greenhouse Gas Emissions Setting The earth's atmosphere naturally contains a number of gases, including (but not limited to) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), which are collectively referred to as greenhouse gases (GHGs). GHG emissions are generally numerically depicted (when applicable) as carbon dioxide APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 30 Less Than Evaluated Would the project: Potentially Significant Less Than No in Previous Significant With Significant Impact Document Mitigation a) Generate greenhouse gas emissions, directly or X indirectly, that may have a significant impact on the environment? b) Conflict with any applicable plan, policy or X regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases? Setting The earth's atmosphere naturally contains a number of gases, including (but not limited to) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), which are collectively referred to as greenhouse gases (GHGs). GHG emissions are generally numerically depicted (when applicable) as carbon dioxide APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 30 Projects that wish to demonstrate consistency with the CAP must demonstrate consistency with all applicable measures and action items from the CAP. For the subject project, consistency with the CAP would not require special provisions because it is not anticipated to result in housing units, non- residential development, or other greenhouse gas producing activities. Discussion a, b) Less Than Significant. The proposed project is the clearing, grading, and terracing of 0.44 acres of land. Generally, GHG emissions that are normally associated with land use projects include: water vapor, carbon dioxide, methane, and nitrous oxide. Grading and clearing activities will not result in a long term net increase in GHG emissions. The project created nominal short-term air emissions, particularly with regard to dust; an ECP has been prepared as part of Grading Plan (refer to Section 3, Air Quality). The project will not interfere with the State's goals of reducing greenhouse gas emissions to 1990 levels by the year 2020, per AB 32, nor would the project conflict with any applicable plan, policy or regulation adopted for the purpose of reducing greenhouse gas emissions. 8.

Setting The property is located in an area designated by CAL FIRE as a Very High Fire Hazard Severity Zone (GP EIR, Figure 4.7-1). The project involves the grading and leveling of land and the removal of vegetation from the graded portion of the site to a 'slash pile' near the entrance to the site. The applicant has agreed to use any chemicals according to the manufacturer's specifications, as reflected in CM#4 below. The use, storage, and disposal of chemicals used within the project boundaries shall be applied pursuant to manufacturer's instructions, subject to all applicable laws, regulations, and permits. Discussion a) No Impact The proposed project would not involve the routine transport, use, or disposal of hazardous materials, and, would not result in such impact. b) No Impact The proposed grading activities and site stabilization measures are not anticipated to result in a release of hazardous materials into the environment. C) No Impact Grading and clearing activities do not involve any emission or handling of any hazardous materials, substances, or waste within one-quarter mile of an existing school. No existing or proposed school facilities are located within a one-quarter mile radius of the project site. d) No Impact The property is not included on a list of sites containing hazardous materials, and would not result in a significant hazard to the public or to the environment. The project site is not included on the Cortese -Knox list compiled pursuant to Government Code Section 65962.5. e) No Impact The proposed project site is not located within an airport land use plan or within two miles of a public airport and the project would not result in permanent structures that expose people to a safety hazard. APN 058-650-016 Grading Permit December2014 Initial StudylMitigated Negative Declaration Page 33 No Impact The proposed project site is not located within the vicinity of a private airstrip and the project would not result in permanent structures that expose people to a safety hazard. g) No Impact The proposed project does not include any actions within the roadway that would physically interfere with any emergency response or emergency evacuation plans. The project would not result in an increase in traffic, and thus would not reduce the current level of service of the area road network. h) Less than Significant with Mitigation.. The property is located in an area designated by CAL FIRE as a Very'High Fire Hazard Severity Zone (GP EIR, Figure 4.7-1). The project involves the grading and leveling of land and the removal of vegetation from the graded portion of the site to a 'slash pile' near the entrance to the site. Comprised of dead and dry vegetation, the slash pile provides fuel for wild1fires that may occur near the project site. Decomposition and ignition of the slash pile can also occur over time. For these reasons, the removed vegetation associated with grading activities could expose people or structures to a significant risk of wildland fires. Mitigation Measure MM2 requires that vegetation cleared during grading activities be handled appropriately by one of three methods: removing to a permitted green waste facility, chipping and distributing the materials on site, or burning the materials consistent with a valid burn permit from the BCAQMD. With the removal of cleared vegetation, any fire hazard associated with grading permit activities will be less than significant. Mitigation: Mitigation Measure MM2 (Removal of Cleared Vegetation) A note on the final grading plan states: "All vegetation cleared during grading,activities shall be removed from the project site by one of three methods: removing vegetation to a permitted green waste facility, chipping and distributing the materials on site, or burning cleared vegetation consistent with a valid burn permit from the Butte County Air Quality Management district (BCAQMD)." Plan Requirements: Remove fire danger from cleared (downed, dead) vegetation. Timing: Prior to the Public Works Director singing off the final Grading Permit. Monitoring: Public Works Land Development will ensure cleared vegetation is removed prior to final grading approval. 9.

Compliance with these measures would ensure the project would not violate any water quality standards. Conservation Measure# CMI (Stormwater BMW The following is a list of BMPs, have been incorporated into the proposed Grading Plan, by the applicant: 1. If one or more acres of ground is to be disturbed, a permit shall be obtained from the State Water Resources Control Board prior to construction. 2. All erosion control measures shall conform to the Caltrans standard specifications May 2006 (See Appendix A and B to this study) and the erosion control plans shown on the construction drawings. 3. Interim erosion control measures shall be installed as needed during construction to assure adequate erosion control facilities are in place at all times. 4. All slopes with disturbed soils greater than 10% that are free of vegetation shall have earth guard applied or mulch spread and tacked down prior to a 30% chance of rain. 5. Dust control measures in the form of water application to all exposed soil surfaces to prevent the transport of soil from exposed surfaces on construction sites in the form of airborne particulates. Watering of exposed soil surfaces shall occur at least twice daily, preferably in the late morning and after work is done for the day. All clearing, grading, earth moving or excavation activities shall cease when winds exceed 15 mph averaged over 1 hour. 6. To minimize the tracking of mud and dirt and to stabilize the point of ingress/egress by construction vehicles the contractor should place 4" to 6" angular rock with a minimum depth of 12" in conjunction with an underlay of filter fabric. Any soil material carried onto street surfaces by construction equipment shall be removed on a daily basis. (broom clean- do not use water to wash the street) If equipment traffic is minimal, stabilized entrance may not be needed. Any sediment tracked off the property and onto paved roadways shall be swept immediately after each vehicle leaves the site. 7. Haul trucks shall be covered with tarpaulins or other effective covers at all times. 8. If the construction site is to remain inactive longer than 14 days then the site shall be stabilized by applying "earth guard" or seeded and watered until grass cover is grown. 9. Inspect sediment control devices before each storm to verify they are in proper order. Inspect the sediment control devices after each storm, removing collected sediment and repairing deficiencies. 10. During long periods of rain and high intensity rainfall, BMPs may become clogged. Extreme care should be taken to clean BMPs to reduce fugitive discharge and potential flooding. APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 36 11. Applicant may remove temporary BMPs (wattles and silt fencing) once permanent BMPs have been established. 12. Native seed and erosion control matting shall be applied to all disturbed areas that are not subject to heavy wear from construction equipment or other vehicles. Irrigation will be performed by hand watering. Seed and mulch shall be kept moist at all times until germination has occurred. Seed should be in conformance with the California State Seed Law and applied at the following rate: , Seed - Melica californica: 10 lbs/acre Fiber - 100% wood fiber: 2,000 lbs/acre Tack - Scilium based "M" binder 120 lbs/acre The project includes an ECP (Figure 3), which is part of the Grading Plan. The following is a list of measures that will be implemented, as part of the Erosion and Sediment Control Plan: 1. If BMP's are damaged in a storm, repairs should be completed within 72 hours. Care should be exercised to minimize damage and protected areas while making repairs. 2. If BMP's have failed, or are ineffective, notify the owner/contractor to modify the BMP or specify an alternative. The modification or alternative should be installed within 72 hours of approval 3. If seeds fail to germinate, or they germinate and die, the area must be re -seeded, fertilized, and mulched within the planting season. Not less than half the original application rate should be applied. 4. Straw wattles shall have a minimum functional longevity of 1 year and shall be replaced annually if required beyond 1 year. 5. Upon permanent stabilization, and approval of the engineer, temporary BMPs may. be removed if no longer needed. b) No Impact No activities associated with the project are anticipated to have any impact on ground water. Project activities are limited to surface grading for the leveling and terracing of land. C) Less Than Significant Impact. The project activities include grading and leveling of land on a 0.44 -acre portion of a 10.1 -acre site. The overall direction of drainage on the site will not change. The terracing, along with erosion BMP's will serve to slow the rate of runoff from the site, not accelerate it. No streams or rivers will have their course altered as a result of project activities. d) No Impact The project does not lie in an area designated as a FEMA flood zone nor is it immediately adjacent to any areas that are designated as flood zones (GP EIR, Figure 4.8-3). Furthermore, the project activities involve the leveling'of already sloped land. There is no APIV058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 37 net change in the flow of water on or off the site that would lead to an increase in flooding - on- or off-site. e) Less Than Significant Impact The project will not yield an increase in storm water runoff that would require the use or construction of storm water drainage facilities. As addressed in Item a) above, the Grading Plan and ECP will meet water quality standards and not result in polluted runoff. f) Less Than Significant Impact Refer to Item a) above. The ultimate goal of an Erosion Control Maintenance plan is to prevent degradation of water quality through the prevention of sediment and pollutant runoff. The ECP is project specific and designed to minimize erosion, thereby protecting water quality. g -i) No Impact The proposed project, which is grading and clearing activities, is not located within a 100 -year flood hazard area. Project activities would not result in placing housing in a 100 -year flood hazard area, nor would activities impede or redirect flood flows. The project would not expose people or structures to significant risk of loss, injury or death involving flooding as a result of levee or dam failure. No Impact There are no anticipated impacts to the proposed project from seiche, tsunami, or mudflow, as no topographical features of water bodies capable of producing such events occur within the project site vicinity. 10, Land Use and Planning Discussion a) No Impact Grading activities have been conducted on a 0.44 -acre site within a 10.1 -acre property. The site is located in the foothills of the Sierra Nevada Mountains and is rural in nature, with no surrounding neighborhoods. Therefore, the project will not have an impact on the physical arrangement of an established community. b) No Impact The proposed project is consistent with the General Plan Land Use designation of Foothill Residential and the FR -20 (Foothill Residential, 20 -acre minimum parcel size) zoning designation. The project would neither propose a change in zoning, nor conflict with APN 058-650-016 Grading Permit Initial Studyllditigated Negative Declaration December2014 Page 38 LessThan Would the project: Potentially Significant Less Than No Significant With Significant Impact Mitigation a) Physically divide an established community?

Discussion a) No Impact Grading activities have been conducted on a 0.44 -acre site within a 10.1 -acre property. The site is located in the foothills of the Sierra Nevada Mountains and is rural in nature, with no surrounding neighborhoods. Therefore, the project will not have an impact on the physical arrangement of an established community. b) No Impact The proposed project is consistent with the General Plan Land Use designation of Foothill Residential and the FR -20 (Foothill Residential, 20 -acre minimum parcel size) zoning designation. The project would neither propose a change in zoning, nor conflict with APN 058-650-016 Grading Permit Initial Studyllditigated Negative Declaration December2014 Page 38 any applicable land use plan, policy, or regulation of any agency with jurisdiction over the site. C) No Impact The project site is not currently located in an area identified as having an adopted Habitat Conservation Plan, Natural Community Conservation Plan. In addition, available information indicates that once approved, the Butte Regional Conservation Plan's jurisdictional area will not encompass the project site. APN 058-650-016 Grading Permit December2014 Initial Study/Mitigated Negative Declaration Page 39 Discussion a) Less Than Significant The Butte County Board of Supervisors passed Ordinance #4053, Noise Control on March 26, 2013. The Ordinance became effective on April 25, 2013. The Ordinance states: Noise sources associated with construction, repair, remodeling, demolition, paving or grading of any real property or public works project located within 1,000 feet of residential uses, provided said activities do not take place between thefollowing hours: • Sunset to sunrise on weekdays and non -holidays; • Friday commencing at 6:00 p.m. through and including 8.00 a.m. on Saturday, as well as not before 8:00 a.m. on holidays; • Saturday commencing at 6:00 p.m. through and including 10:00 a.m. on Sunday; and, 0 Sunday after the hour of 6:00 p.m. Provided, however, when an unforeseen or unavoidable condition occurs during a construction project and the nature of the project necessitates that work in process be continued until a specific phase is completed, the contractor or owner shall be allowed to continue work into the hours delineated above and to operate machinery and equipment necessary to complete the specific work in progress until that specific work can be brought to conclusion under conditions which will not jeopardize inspection acceptance or create unduefinancial hardshipsfor the contractor or owner. Additional grading activities are not anticipated. However, if grading were necessary, the implementation of the provisions of the Noise Ordinance would reduce any temporary and periodic increase in noise levels to less than significant levels. b) Less Than Significant The project encompasses grading and clearing on 0.44 acres, most of which has been conducted. Although additional grading activities are not anticipated, any activities such as site stabilization would be temporary, occur during less sensitive daytime hours, and short in duration. As a result, any potential impacts from grading -related groundborne vibrations or noises would be less than significant. c) No Impact The proposed project does not involve uses or activities that would result in a substantial permanent increase in ambient noise levels in the project vicinity. Although additional grading activities are not anticipated, noise associated with any additional activities would be temporary. d) Less Than Significant The property is located in a rural area with generally low noise levels and is not subject to any significant continuous noise. The nearest residence is approximately 500 ft of project activities. Any additional grading activities on the site would temporarily generate an increase in noise levels on and adjacent to the site. However, noise levels would be temporary and would not be in excess of local standards. APN 058-650-016 Grading Permit. December2014 Initial StudylMitigated Negative Declaration Page 41 e, No Impact. The proposed project is not located within an airport land use plan or within two miles of a public airport, public use airport, or private airstrip. As such, the project would not expose people residing or working in the project area to excessive noise levels. 13. Population and Housing Discussion a) Less Than Significant No significant population growth associated with the proposed project is expected. Any employment generated by grading activities would be temporary and drawn from the local work force, and would not create a permanent population growth to the area. b, c) No Impact; As stated under Item a) above, grading activities will not generate a permanent increase to the local population that would displace existing housing or add a substantial number of people, necessitating the construction of replacement housing elsewhere. 14.

The issuance of a Grading Permit, and any site stabilization would not substantially increase hazards due to a transportation design feature. New roadways are not proposed as part of this project. e),, No Impact No existing residential uses are located on the project site, and the proposed project would not generate a permanent increase in traffic volumes to cause the existing, road network to have inadequate emergency access. No Impact. The proposed project would not generate a permanent increase in population growth to the project area that would cause an increase in demand for alternative transportation facilities, or otherwise decrease the performance or safety of such facilities. 17. Utilities and Service Systems APN 058-650-016 Grading Permit December 2014 initial Study/Mitigated Negative Declaration Page 45 Less Than Would the project: Potentially Significant Less Than No Significant With Significant Impact Mitigation a) Exceed wastewater treatment requirements of the applicable Water Quality Control X Board? b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the X construction of which could cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of X which could cause significant environmental effects? d) Have sufficient water supplies available to serve the project from existing entitlements X and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider which serves/may serve the project that it has X adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity to accommodate the X project's solid waste disposal needs? APN 058-650-016 Grading Permit December 2014 initial Study/Mitigated Negative Declaration Page 45 Discussion a,b,e) No Impact. The project does not include construction or expansion of wastewater treatment facilities. C) No Impact No existing stormwater drainage facilities are located on the project site and none would be required with approval of the proposed project due to project site having adequate area within the project site to allow stormwater to infiltrate into the ground before leaving the site. d) No Impact The site is located in a rural area of Butte County where water services are provided by individual groundwater wells. The well located on the property provides domestic water to the residence onsite. The availability of groundwater in the area depends largely upon the geologic, hydrologic and climatic conditions of the project area. Though the' availability of existing water supplies is uncertain due to the variability of site conditions, water demand for other activities would not be greater than what would be permitted from ,other allowed uses within the Foothill Residential (FR -20) zoning. Therefore, the project will not require new or expanded water entitlements. f, g) No Impact Grading and clearing activities resulted in green waste that was burned on-site. Issuance of a Grading Permit would not result in an increase of solid waste to the Butte County Neal Road Landfill. The project would not impact federal, state, and local statutes related to solid waste.

It shall be mitigated by one or more of the following: replanting and maintaining oak trees, establishing conservation easements, contributing funds for off-site oak woodlands conservation, and/or other mitigation measures developed by Butte County. Replanting oak trees cannot account for more than one-half ofthe mitigation. Replanted oak trees shall be maintained for a period of seven years after they are planted. If any of the replanted oak trees die or become diseased, they shall be replaced and maintained for seven years after the new oak trees are planted; 3)A replanting schedule and diagram for trees removed or encroached upon by permit activities consistent with PRC §21083.4(b)(2), applicable mitigation measures, and Butte County Ordinance, if any, shall be submitted to and approved by the Director of Development Services or his/her designee. Replanted trees shall be planted in areas deemed appropriate by the Plan, considering future lot development, interference with foundations, fencing, roadways, driveways, and utilities. Trees planted shall be protected from livestock and other animals; 4)Oak Tree protection measures for trees to be retained within the project site shall be included in construction specifications. Each oak tree to be preserved shall be surrounded by a tree zone identified by the drip line of the tree. An orange plastic fence or other suitable type of fence shall beiised to identify the tree zone during construction activities. No vegetation removal, soil disturbance, or other development activities shall occur within the tree zone in order to protect root systems and minimize compaction of the soil, unless authorized by Oak Tree Mitigation Plan; and 5)Conservation easements or funds for off-site oak woodlands conservation shall be proposed to and approved by the Director of Development Services or his/her designee." Plan Requirements: No vegetation removal, grading, road construction, or other earthwork shall be permitted until the Oak Tree Mitigation Plan is submitted and approved. Timing: Requirements of the condition shall be satisfied prior final acceptance of the grading permit, and prior to any development activity or the issuance of any grading, building, septic, or well permit, or the approval of any improvement plans on the parcels. APN 058-650-016 Grading Permit December 2014 Initial Study/Mitigated Negative Declaration Page 48 Monitoring: The Butte County Department of Development Services and Department of Public Works shall ensure thatthis mitigation is complied with prior to final acceptance of the grading permit. I Conservation Measure CM#1 (Stormwater BM"s Conservation Measure #1, the following is a list of BMPs, have been incorporated into the proposed Grading Plan, by the applicant: 1. If one or more acres of ground is to be disturbed, a permit must be obtained from the state water resources control board prior to construction. 2. All erosion control measures shall conform to the Caltrans standard specifications May 2006 (See Appendix A and B to this stud) and the erosion control plans shown on the construction drawings. 3. Interim erosion control measures may be needed and shall be installed during construction to assure adequate erosion control facilities are in place at all times. 4. All slopes with disturbed soils greater than 10% that are free of vegetation shall have earth guard applied or mulch spread and tacked down prior to a 30% chance of rain. Dust control measures in the form of water application to all exposed soil surfaces to prevent the transport of soil from exposed surfaces on construction sites in the form of airborne particulates. Watering of exposed soil surfaces shall occur at least twice daily, preferably in the late morning and after work is done for the day. All clearing grading, earth moving or excavation activities shall cease when winds exceed 15 mph averaged over 1 hour. 6. To minimize the tracking of mud and dirt and to stabilize the point of ingress/egress by construction vehicles the contractor should place 4" to 6" angular rock with a minimum depth of 12" in conjunction with an underlay of filter fabric. Any soil material carried onto street surfaces by construction equipment shall be removed on a daily basis. (broom clean- do not use water to wash the street) If equipment traffic is minimal, stabilized entrance may not be needed. Any sediment tracked off the property and onto paved roadways shall be swept immediately after each vehicle leaves the site. 7. Haul trucks shall be covered with tarpaulins orother effective covers at all times. , 8. If the construction site is to remain inactive longer than 14 days then the site shall be stabilized by applying "earth guard" or seeded and watered until grass cover is grown. 9. Inspect sediment control devices before each storm to verify they are in proper order. Inspect the sediment control devices after each storm, removing collected sediment and repairing deficiencies. APN 058-650-016 Grading Permit December 2014 Initial StudylMitigated Negative Declaration Page 49 10. During long periods of rain and high intensity rainfall, BMPs may become clogged. Extreme care should be taken to clean BMPs to reduce fugitive discharge and potential flooding. 11. Applicant may remove temporary BMPs (wattles and silt fencing) once permanent BMPs have been established. 12. Native seed and erosion control matting shall be applied to all disturbed areas that are not subject to heavy wear from construction equipment or other vehicles. Irrigation will be performed by hand watering. Seed and mulch shall be kept moist at all times until germination has occurred. Seed should be in conformance with the California State Seed Law and applied at the following rate: Seed - Melica californica: 10 lbs/acre Fiber - 100% wood fiber: 2,000 lbs/acre Tack - Scilium based "M" binder 120 lbs/acre Consenm-tion Measure CM#2 (Erosion Control Plan) The project includes an Erosion and Sediment Control Plan (Figure 3), which is part of the Grading Plan. The following is a list of measures that will be implemented, as part of the Erosion and Sediment Control Plan: 1. If BMP's are damaged in a storm, repairs should be completed within 72 hours. Care should be exercised to minimize damage and protected areas while making repairs. 2. If BMP's have failed, or are ineffective, notify the owner/contractor to modify the BMP or specify an alternative. The modification or alternative should be installed within 72 hours of approval 3. If seeds fail to germinate, or they germinate and die, the area must be re -seeded, fertilized, and mulched within the planting season. Not less than half the original application rate should be applied. 4. Straw wattles shall have a minimum functional longevity of 1 year and shall be replaced annually if required beyond 1 year. 5. Upon permanent stabilization, and approval of the engineer, temporary BMPs may be removed if no longer needed. The project also includes dust suppression measures to reduce dust and particulate matter associated with grading activities. These include - 1. Conduct daily cleanup. This practice shall include removal of mud and dust carried onto street surfaces by construction vehicles. During clearing grading, earth -moving, excavation, or transportation of cut or fill materials, water trucks or sprinkler APN 058-650-016 Grading Permit December2014 Initial Study/Mitigated Negative Declaration Page 50 systems are to be used to prevent dust from leaving the site and to create a crust after each day's activities cease. 2. Cover haul trucks with tarpaulins or other effective covers at all times, except when loading or unloading materials. 3. Water all exposed earth surfaces. This practice shall be conducted at a minimum in the late morning and at the end of the day. Further, the frequency of watering shall increase if required by the Butte County Air Pollution Control District. 4. All clearing, grading, earth -moving, or excavation activities shall cease when winds exceed 15 mph averaged over 1 hour. 5. The area disturbed by demolition, clearing, grading, earth -moving, or excavation operations shall be minimized at all times. 6. Portions of the construction site to remain inactive longer than a period of 14 days shall be seeded and watered until grass cover is grown. 7. The applicant shall minimize construction -related exhaust emissions by maintaining construction equipment engines in good condition and in proper tune according to manufacturer's specifications and during smog season (May through October) by not allowing construction equipment to be left idling for long periods. 8. All on-site vehicles should be limited to a speed of 15 mph on unpaved roads. 9. Re -vegetate exposed surfaces. This shall be completed as soon as possible to reduce dust emissions. The Dust Suppression Plan shall be submitted to the County of Butte for review and approval prior to issuance of a grading permit. 10. Soil stockpiled for more than two days shall be covered, kept moist, or treated with soil binders to prevent dust generation. 11. Burning of vegetative material may be undertaken only after obtaining a valid burn permit issued by the BCAQMD (Rule 300 Open Burning Requirements) and in compliance with the conditions specified on the permit. 12. Other measures as determined appropriate by the Butte. County Air Quality Management District and Department of Public Works to reduce dust.
