A. RECITALS. 1. The property owner, Diamond Hills Ranch Partnership and applicant, SunCal Companies has filed an application for F" Vesting Tentative Map (VTTM) No. 52267 in order to subdivide a 339.3 acre parcel into 141 lots for the eventual development of 130 detached single family homes. The project site is generally located east of Diamond Bar Boulevard, and north of Grand Avenue at the extension of Highcrest Drive, Diamond Bar, Los Angeles County, California, as described above in the title of this Resolution. The request also includes: a Conditional Use Permit for development within an urban hillside f, management area (CUP No. 98-3), an Oak Tree Permit (OT No. 98-1) for the removal of oak trees, the removal of a' map restriction, and the dedication of 274.3 acres of Tract No. 52267 and all of Lot 9 of Tract No. 31479 to public, open space. 2. On April 18, 1989, the City of Diamond Bar was established as a duly organized municipal corporation of the State of California. Thereafter, the City Council of the City of Diamond Bar adopted its Ordinance No. 14 (1990), thereby adopting the Los Angeles County Code as the ordinances of the City of Diamond Bar. Title 21 and 22 of the Los Angeles County Code contain the Development Code of the County of Los Angeles now currently applicable to development applications, including the F-3 subject Application, within_ the Citv.of Diamond Bar. 3. The Planning Commission of the City of Diamond Bar on = February 10, 1998 conducted a duly noticed public hearing on CUP No. 98-03 and OT No. 98-01. The public hearing was opened and comments were received on the project, 1 B. draft Environmental Impact Report No..97-2 (SCH NO. 97031005), CUP No. 98-03 and OT No. 98-01. At that time, the public hearing was continued to February 24, 1998. The public hearing was again continued -to March 24, 1998 and to April 28, 1998. On April 28, 1998 public comments were received and then the public hearing was closed. At that time, the Commission directed staff to prepare appropriate documents and return them to the Commission on May 12, 1998 4. Notification of the Application's public hearing has been made in the San Gabriel Valley Tribune and Inland Vallev Daily Bulletin newspapers on January 21, 1998. Nine hundred and twenty-nine property owners, within a minimum 500 foot radius of the project site were notified by mail on January 20, 1998. Resolution. NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: 1. This Planning Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. The Planning Commission hereby determines that the project identified above in this Resolution requires an Environmental Impact Report (EIR). EIR No. 97-2 (SCH NO. 97031005) has been prepared according to the California Environmental Quality Act (CEQA) of 1970, gs amended, and the guidelines promulgated thereunder. Furthermore, this Planning Commission has reviewed the EIR in reference to CUP No. 98-03 and OT No. 98-01. 3. Based on the findings and conclusions set forth herein, this Planning Commission hereby finds as follows: (a) The project relates to,a vacant parcel of approximately 339:3 acres (Lots 4, 5, 6, and 7) of, Tract No. 31479. Additionally, the project relates to Lot 9 of Tract No. 31479 which in its entirety will be dedicated to public open space. (b) The project proposes to subdivide 65 of the 339.3 acres into 141 lots for the development of 130 detached single family homes within a private, gated community; remove and replace oak and walnut trees; h and remove the map restriction on a portion of the 65 acres. The balance of the 339.3 acres (274.3 acres) and all of Lot 9 of Tract No. 31479 will be dedicated to the City as public, open space. (c) The *project site has a General Plan land use designation of Plarn�iny Atea 2. The proposed project complies with the General Plan and Planning Area 2 as defined in the General Plan. The project site is zoned Residential Planned Development - 2 Minimum Lot Size 20,000 Square Feet -2 Units Per Acre (RPD-20,000-2U)r�-, (d) Generally, the following zones surround the project r- site: to the north and east is the RPD -20,000-2U Zone; to the south is the Single Family Residence - Minimum Lot Size 40,000 Square Feet (R-1-40,000) and the RPD -20,000-2U Zone; and to the west is the Single Family Residence -Minimum Lot Size 8,000 Square Feet (R-1-8,000) Zone. Conditional Use Permit Hillside Management Area (e) The proposed project is located and designed so as to protect the safety of current and future community residents, and will not create significant threats to life and/or property due to the presence of geologic, seismic, slope instability, fire, flood, mud flow, or erosion hazard. The on-site effects from the development of VTTM No. 52267 will not result in any significant geologic, seismic, slope instability, fire, flood, mud flow, or erosion hazard because the project's grading plan is consistent with the City's Hillside Management Ordinance and will be developed with the benefit of appropriate City permits and inspections. Slope instability will not occur due to the -9_ introduction of project features like shear keys and buttress fills which have been incorporated into the project's grading design in accordance with the recommendations of the applicant's geotechnical engineer and the City's grading ordinance requirements for slope stability. Additionally, engineered slopes on-site do not exceed 2:1 and meet the City's stability requirements. No active faults are known to transect the project site or the immediate site vicinity. The probability of on-site surface rupture or deformation from an earthquake is considered very low. However, ground shaking hazards caused by - earthquakes along active regional faults do exist. All structural improvements will be designed in = accordance with the Uniform Building Code requirements applicable to geologic conditions at the project site. The project site varies from an elevation of approximately 810 above sea level (msl) along the =Y western boundary to approximately 1,150 msl at its ' eastern edge. Several natural drainages convey site runoff -from -the proposed development area and `- existing adjacent residential projects to culverts in Diamond Bar Boulevard. The balance of the 339.3 acres will remain in its natural conditions. During 3 the geotechnical evaluation of the project site, no groundwater was encountered. Although the proposed project will alter the existing natural drainage patterns on-site, drainage will be conveyed by on- site storm drain systems to existing natural drainage courses, which then drain to existing culverts in Diamond Bar Boulevard. The receiving storm drain systems are adequately sized and have adequate available capacity to accommodate these flows. Drainage from the project site will not alter natural drainage or impact rare or threatened biological resources. Additionally, during construction, short-term water quality impacts may occur from erosion and siltation from soils exposed by grading activities. The Federal Clean Water Act establishes a framework for regulating potential water quality impacts from construction activities through the National Pollutant Discharge Elimination System (NPDES) program. Therefore, the applicant is required to obtain a'permit from the Regional Water Quality Control Board. Stormwater pollutant prevention plans are required which includes both structural and nonstructural Best Management Practices (BMPs) to reduce water quality impacts. Erosion controlwillbe required. Full compliance with applicable local, State and Federal water quality standards by the applicant will reduce impacts to less than significant. The proposed project will comply with the required standards of the Los Angeles County Fire Department. A fuel modification plan, appropriate access and turnarounds for fire equipment, and fire hydrants in appropriate locations with adequate flow are conditions of approval as specified by the Fire Department. The project will result in short-term construction impacts related to fugitive dust and equipment exhaust emissions. Short-term emissions will exceed the SCAQMD's 100 pounds/day threshold for nitrogen oxides (NOx)•and its 150 pounds/day threshold of particulate matter (PM10). Mitigation measures are incorporated into the project to reduce the construction related air quality emissions to the extent feasible. However, the emissions can not be mitigated to a level considered less than significant. Therefore, the City will require that all construction comply with the SCAQMD's regulations, including Rule 402 and 403. As a result, these unavoidable effects are acceptable - when balanced against the facts set forth in the project's Statement of overriding Consideration. It is the above referenced standards that will reduce the threat to life and/or property. N '9 (f) The proposed project is compatible with the natural, biotic; cultural, scenic and open space resources of the area. The compatibility of the proposed project with the natural, biotic, cultural, scenic and open space _. resources was reviewed through the EIR process. A biological reconnaissance survey and cultural resource studies were taken according to industry standards and practices. Additionally, scenic and open space resources were reviewed. The EIR incorporates a Mitigation Monitoring Program (MMP) that mitigates potentially significant impacts to the natural and biotic resources. The measures within the MMP are based on the -findings from the .biological resources survey and previously adopted conditions by the City placed on projects containing similar resources, The MMP also incorporates the following: avoidance of approximately 274 acres of a variety of plant communities; protection through a Biological Resource Management Plan of habitat replacement and revegetation and their protection during construction; restoration of coastal sage scrub species and oak and walnut tree replacement; and appropriate permits from U.S. Army Corps of Engineers and California Department of Fish and Game. Through the MMP and appropriate permits, the biological impacts can be mitigated to'a level that is considered less than significant. A Mitigation Landscape Plan, a condition of approvhl,for this project, will incorporate the necessary requirements to comply with the mitigation measures, thereby ensuring this project's compatibility with the areas natural and biotic resources. No know or recorded prehistoric or historic sites are located with the proposed project. However, ground visibility was poor. The lower and less steep benches that overlook the canyon and lower drainage, are likely locations for prehistoric camp sites. Therefore, to reduce the impact on cultural resources, the MMP incorporates measures such as an archaeologist and paleontologist to monitor all clearing, brushing and grading activities on the project site. This will ensure appropriate actions for the exploration and/or salvage of the cultural findings. When combined with other projects that may be developed and existing development in this area of the City, the proposed project is not expected to contribute to cumulative aesthetics/visual impacts. The General Plan indicates that a single family - development of 130 homes would_be,-allowed"in this area. Compliance with the City's"Hillside 5 Management Ordinance is required to ensure that potential view impacts are mitigated to the extent feasible. Aesthetic and visual impacts will be mitigated through techniques stated within the Mitigation Monitoring Plan (MMP). It is unknownGG�';''�, whether the mitigation measures identified in the MMP will reduce the project's aesthetic impacts to a level that would be considered less than significant. 'Therefore,'the impacts identified within the EIR are considered significant and unavoidable and a Statement of overriding Consideration will be prepared addressing this issue. (g) The proposed project is conveniently served by neighborhood shopping and commercial facilities, can be provided with essential public services without imposing undue costs on the total community, and is consistent with the objectives and policies of the - General Plan. Previously mentioned findings confirm that the proposed project is consistent with the objectives and policies of the General Plan. Pursuant to the EIR, this project and area surrounding the project is served by the Los Angeles County Fire and Sheriff Departments, as well as the Pomona Unified School District. The facilities of the Pomona Unified School District are inadequate and elementary facilities demand the construction of the new Pantera School. The district has onlST 50 percent of the resources to commit to the new school's construction. Unfortunately, school mitigation fees from this tract will only provide less than an additional 25 percent. A supplemental fee to create a 50 percent contribution by the applicant is being considered by the school district to mitigate this issue. . Additionally, the applicant will provide its fair share for infrastructure related to this project. Furthermore, adequate shopping and commercial facilities are provided within approximately one miles of the project site. (h) The proposed development demonstrates creative and imaginative design, resulting in a visual quality' that will complement community character and benefit current and future community residents. The proposed development demonstrates creative and imaginative design through the utilization of the standards and guidelines of the City's Hillside Management ordinance; the varying shape lots with irregular pad configuration; density pursuant to the General Ply. e = the dedicat;.on of n,. .-,,Xal, public, open space; -the retention of the area's hillside character through landform grading and the 10 L_, cannot be satisfactorily mitigated. Pursuant to the City's grading permit process and the project's MMP, during construction measures to prevent erosion, such as the use of silt fencing or hay bales shall be installed at the grading limits. Additionally, the revegetation plan will be implemented after feasible when grading is completed. Therefore, soil erosion will be satisfactorily mitigated. (k) The removal or relocation of the oak tree(s) proposed is necessary, as continued existence at present location(s) frustrates the planned improvement of proposed use of the subject property to such an extent that placement of such tree(s) precludes the reasonable and efficient use of such property for a use otherwise authorized. . The removal of oak and walnut trees is necessary to provide slope stability by the introduction of project features like shear keys and buttress fills in accordance with the recommendations of the applicant's geotechnical engineer and the City's grading ordinance requirements. Additionally, the project's development area as cited within the General Plan, also causes the removal of oak and walnut trees. However, the MMP requires oak trees with a trunk diameter less than 36 inches will be replaced at a 2:1 ratio; oak trees with diameters between 36 inches and 48 inches will be replaced at a 3:1 ratio; oaks trees with diameters greater than 48 inches will -be replaced at a 4:1 ratio;_and ;,walnut; tree replacement at a=2:1 ratio. All tree replacement will include understory to ensure the Revegetation Plan, which will concentrate the planting of vegetation in concave areas, similar as in nature. All these measures will complement the community's character, benefitting current and future community residents. i Oak Tree Permit (i) The proposed construction or proposed use will be accomplished without endangering the health of the remaining trees on the subject property. Pursuant to the City's Development Code, Biological Resource Management Plan, the project's MMP, preconstruction meetings and the project biologist, remaining trees shall be protected at all times during construction. (j) The removal or relocation of the oak tree(s) ;x proposed will not result in soil erosion through the diversion of increased flow of surface waters which L_, cannot be satisfactorily mitigated. Pursuant to the City's grading permit process and the project's MMP, during construction measures to prevent erosion, such as the use of silt fencing or hay bales shall be installed at the grading limits. Additionally, the revegetation plan will be implemented after feasible when grading is completed. Therefore, soil erosion will be satisfactorily mitigated. (k) The removal or relocation of the oak tree(s) proposed is necessary, as continued existence at present location(s) frustrates the planned improvement of proposed use of the subject property to such an extent that placement of such tree(s) precludes the reasonable and efficient use of such property for a use otherwise authorized. . The removal of oak and walnut trees is necessary to provide slope stability by the introduction of project features like shear keys and buttress fills in accordance with the recommendations of the applicant's geotechnical engineer and the City's grading ordinance requirements. Additionally, the project's development area as cited within the General Plan, also causes the removal of oak and walnut trees. However, the MMP requires oak trees with a trunk diameter less than 36 inches will be replaced at a 2:1 ratio; oak trees with diameters between 36 inches and 48 inches will be replaced at a 3:1 ratio; oaks trees with diameters greater than 48 inches will -be replaced at a 4:1 ratio;_and ;,walnut; tree replacement at a=2:1 ratio. All tree replacement will include understory to ensure the 4. replacement of the ecosystem values. Each acre of coastal sage scrub lost, two acres will be replaced (2:1 ratio). Additionally, a five year monitoring will occur with performance standards of 90 percent coverage by the fifth year.

NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: 1. This Planning commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. The Planning Commission hereby determines that the - project identified above in this Resolution requires an Environmental Impact Report (EIR). EIR No. 97-2 (SCH NO. 97031005) has been prepared according to the California Environmental Quality Act (CEQA) of 1970, gs amended, and the guidelines promulgated thereunder. Furthermore, this Planning commission has reviewed the EIR in reference to CUP No. 98-03 and OT No. 98-01. 3. Based on the findings and conclusions set forth herein, this Planning,Commission hereby finds as follows: (a) The project relates to,a vacant parcel of approximately 839:3 acres (Lots 4, 5, 6, and 7) of. Tract No. 31479. Additionally, the project relates to Lot 9 of Tract No. 31479 which in its entirety will be dedicated to public open space. (b) The project proposes to subdivide 65 of the 339.3 acres into 141 lots for the development of 130 detached single family homes within a private, gated community; remove and replace oak and walnut trees; and remove the 'map restriction on a portion of the 65 acres. The balance of the 339.3 acres (274.3 acres) and all of Lot 9 of Tract No. 31479 will be dedicated to the City as public, open space. (c) The project site has a General Plan land use detignation of Planning ALea 2. The proposed project complies with the General Plan and Planning Area 2 as defined in the General Plan. The project site is zoned Residential Planned Development Minimum Lot Size 20,000 Square Feet -2 Units Per Acre (RPD -20,000-2 Generally, the following zones surround the project site: to the north and east is the RPD -20,000-2U Zone; to the south is the Single Family ResidenceMinimum Lot Size 40,000 Square Feet (R-1-40,000) and the RPD - 20,000 -2U Zone; and to the west is the Single Family Residence -Minimum Lot Size 8,000 Square Feet (R-1-8,000) Zone. Conditional Use Permit Hillside Management Area (e) The proposed project is located and designed so as to protect the safety of current and future community residents, and will not create significant threats to life and/or property due to the presence of -geologic, seismic, slope instability, fire, flood, mud flow, or erosion hazard. The on-site effects from the development of VTTM No. 52267 will not result in any significant geologic, seismic, slope instability, fire, flood, mud flow, or erosion hazard because the project's grading plan is consistent with the City's Hillside Management ordinance -and will be developed with the benefit of appropriate City permits and inspections. Slope instability will not occur due #—o the introduction of project features like shear keys and buttress fills which have been incorporated into the project's grading design in accordance with the recommendations of the applicant's geotechnical engineer and the City's grading ordinance requirements for slope stability. Additionally, engineered slopes on-site do not exceed 2:1 and meet the City's stability requirements. No active faults are known to transect the project site or—the immediate site vicinity. The probability of on-site surface rupture or deformation from an earthquake is considered very low. However, ground shaking hazards caused by earthquakes along active regional faults do exist. All structural improvements will be designed in accordance with the Uniform Building Code requirements applicable to geologic conditions at the project site. The project site varies from an elevation of approximately 810 above sea level (msl) along the western boundary to approximately 1,150 msl at its eastern,edge. Several natural drainages convey site - f- -the proposed development area and runoff rom existing adjacent residential projects to culverts in Diamond Bar Boulevard. The balance.of the 339.3 acres will remain in its natural conditions. During the geotechnical evaluation of the project site, no groundwater was encountered. Although the proposed project will alter the existing natural drainage patterns on-site,'drainage_will be conveyed by onsite storm drain systems to existing natural drainage courses, which then drain to existing culverts in Diamond Bar Boulevard. The receiving storm drain systems are adequately sized and have adequate available capacity to accommodate these flows. Drainage from the project site will not alter natural drainage or impact rare or threatened biological resources. Additionally, during construction, short-term water quality impacts may occur from erosion and siltation from soils exposed by grading activities. The Federal Clean Water Act establishes a framework for regulating potential water quality impacts from construction activities through the National Pollutant Discharge Elimination System (NPDES) program. Therefore,the applicant is required to obtain a permit from the Regional Water Quality Control Board. Stormwater pollutant prevention plans are required which includes both structural and nonstructural Best Management Practices (BMPs) to reduce water quality impacts. Erosion control will be required. Full compliance with applicable local, State and Federal water quality standards by the applicant will reduce impacts to less than significant. The proposed project will comply with the required standards of the Los Angeles County Flre Department. A fuel modification plan, appropriate access and turnarounds for fire equipment, and fire hydrants in appropriate locations with adequate flow are conditions of approval as specified by the Fire Department. The project will result in short-term construction impacts related to fugitive dust and equipment exhaust emissions. Short-term emissions will exceed the SCAQMD's 100 pound .s/day threshold for nitrogen oxides (NOx)-and its 150 pounds/day threshold of, particulate matter (PM10). Mitigation measures are incorporated -into the project to reduce the construction related air quality emissions to the extent feasible. However, the emissions can not be mitigated to a level consid 'ered less than significant. Therefore, the City will require that all construction comply with the SCAQMD's regulations, including Rule 402 and 403. As a result, these unavoidable effects are acceptable when balanced against the facts set forth in the project's Statement -of Overriding Consideration. -It is the above referenced standar&—, that will reduce the threat to life and/or property. W_-1 -- The proposed project is compatible with the natural, biotic, cultural, scenic and open space resources of the area. The compatibility of the proposed project with the natural, biotic, cultural, scenic and open space resources was reviewed through the EIR process. A biological reconnaissance survey and cultural resource studies were taken according to industry standards and practices. Additionally, scenic and open space resources were reviewed. The EIR incorporates a mitigation Monitoring Program (MMP) that mitigates potentially significant impacts to the natural and biotic resources. The measures within the MMP are based on the -findings from the biological resources survey and previously adopted conditions by the City placed on projects containing similar resources. The MMP also incorporates the following: avoidance of approximately 274 acres of a variety of plant communities; protection through a Biological Resource Management Plan of habitat replacement and revegetation and their protection during construction; restoration of coastal sage scrub species and oak and walnut tree replacement; and appropriate permits from U.S. Army Corps of Engineers and California Department of Fish and Game. Through the MMP and appropriate permits, the biological impacts can be mitigated to'a level that is considered less than significant. A Mitigation Landscape Plan, a condition of approvAl,for this project, will incorporate the necessary requirements to comply with the mitigation measures, -thereby ensuring this project's compatibility with the areas natural and biotic -resources. No know or recorded prehistoric or historic sites are located with the proposed project. However, ground visibility was poor. The lower and less steep benches that overlook the canyon and lower drainage, are likely locations for prehistoric camp sites. Therefore, to reduce the impact on cultural resources, the MMP incorporates measures such as an archaeologist and paleontologist to monitor all clearing, brushing and grading activities on the project site. This will ensure appropriate actions for the exploration and/or salvage of the cultural findings. When combined with other projects that may be developed and existing development in this area of the city, the proposed project is -not expected to contribute to cumulative aesthetics/visual impacts. The General Plan indicates that a single fa ily im 'development of 130 homes would -1 Management Ordinance is required to ensure that potential view impacts are mitigated to the extent feasible. Aesthetic and visual impacts will be mitigated through techniques stated within the Mitigation Monitoring Plan (MMP). It is unknown whether the mitigation measures identified in the MMP will reduce the project's aesthetic impacts to a level that would be considered less than significant. 'Therefore,'the impacts identified 4thin the EIR are con'idered significant and wi s unavoidable and a Statement of Overriding consideration will be prepared addressing this issue. (g) The proposed project is conveniently served by neighborhood shopping and commercial facilities, can be provided with essential public services without imposing undue costs on the total community, and is consistent with the objectives and policies of the General Plan. Previously mentioned findings confirm that the proposed project is consistent with the objectives and policies of -the General Plan. Pursuant to the EIR, this project and area surrounding the project is served by the Los Angeles County Fire and Sheriff Departments, as well as the Pomona Unified School District. The -facilities of the Pomona Unified School District are inadequate and elementary facilities demand the construction of the new Pantera School. The district has onlSr 50 percent of the resources to commit to the new school's construction. Unfortunately, school mitigation fees from this tract will only provide less than an additional 25 percent. A supplemental fee to create a 50 percent contribution by the applicant is being considered by the school district to mitigate this issue. -Additionally, the applicant will provide its fair share for infrastructure related to this project. Furthermore, adequate shopping and commercial facilities are provided within approximately one miles of the project site. (h) The proposed development demonstrates creative and imaginative design, resulting in a visual quality that will complement community character and benefit current and future community residents. The proposed development demonstrates creative and imaginative design through the utilization of the standards and guidelines of the City's Hillside Management Ordinance; the varying -shape lots with irregular pad configuration; density pursuant to the General the dedication oL public, open space;'the retention of the area's hillside character through landform. grading and the Revegetation Plan,.which will concentrate the planting of vegetation in concave areas, similar as in nature. All these measures will complement the community's character, benefitting current and future community residents. Oak Tree Permit The proposed construction or proposed use will be accomplished without endangering the health of the remaining trees on the subject property. Pursuant to the City's Development Code, Biological Resource Management Plan, the project's MMP, — preconstruction meetings and the project biologist, remaining trees shall be protected at all times during construction. Q) The removal or relocation of the oak tree(s) proposed.will not result in soil erosion through the diversion of increased flow of surface waters which cannot be satisfactorily mitigated. Pursuant to the City's grading permit process and the project's MMP, during construction measures to prevent erosion, such as the use of silt fencing or hay bales shall be installed at the grading limits. Additionally, the revegetation plan will be implemented after feasible when grading is completed. Therefore, soil erosion will be satisfactorily mitigated. 21 (k) The removal or relocation of the oak tree(s) proposed is necessary, as continued existence at present location(s) frustrates the planned improvement of proposed use of the subject property to such an extent that placement of such tree(s) precludes the reasonable and efficient use of such property for a use otherwise authorized. . The removal of oak and walnut trees is necessaryto provide slope stability by the introduction of , project features like shear keys and buttress fills in accordance with the recommendations of the applicant's geotechnical engineer and the City's grading ordinance requirements. Additionally, the project's development area as cited within the General Plan, also causes the removal of oak and walnut trees. However, the MMP requires oak trees with a trunk diameter less than 36 inches will be 'replaced at a 2:1 ratio; oak trees with diameters between 36 inches and 48 inches will be replaced at a 3:1 ratio; oaks trees with diameters greater than 48 inches will -be replaced at a 4:1-?-atio;_and Inut tree replacement at a.2:1 ratio. All tree 4 y replacement will include understory to ensure the replacement of the ecosystem values. Each acre of coastal sage scrub lost, two acres will be replaced (2:1 ratio). Additionally, a five year monitoring will occur with performance standards of 90 percent coverage by the fifth year. 4.
