UNGAR, PRINCIPAL PLANNER SUBJECT: RESOLUTION NO. 95-11: A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DENYING A VARIANCE TO PERMIT THE ENCROACHMENT OF A BEDROOM ADDITION INTO THE SIDE YARD SETBACK AND GRANTING A CONDITIONAL USE PERMIT FOR THE CONSTRUCTION OF A HARD -SURFACED AREA TO BE USED FOR RECREATIONAL PURPOSES AT A SINGLE FAMILY RESIDENCE IN ZONING CASE NO. 526. Mrs. Frances A. Johnson, 4 Buckboard Lane (Lot 34-A-GF) BACKGROUND 1. The Planning Commission approved the attached resolution on August 5, 1995 denying the requested Variance to permit the encroachment of a 387 square foot bedroom addition 15 feet into the west side yard setback and approving a Conditional Use Permit for a 3,096 square foot hard -surfaced area to be used for recreational purposes. During the hearing process, the original size of the proposed play area was reduced from 5,361 square feet to 3,096 square feet. 2. The Commission denied the Variance because the residential building pad coverage would be excessive at 72.7%, additional encroachments would worsen the amount of residential structure within setback areas, does not minimize structural coverage on the pad, leaves little open space between property lines, would further restrict vehicular and pedestrian traffic, would further overdevelopment of the building pad and far exceeds the recommended coverage of 30%. Two tables that summarize the Criteria Sr Major Impacts and Code Requirements for the proposed project are attached. ®Punted on Recycled Paper. 3. The existinghouse and attached garage was constructePin 1965 alongwith g g retaining walls and a swimming pool. In 1979, a remodel of a master bedroom and bath included an addition of 150 square feet. 4. Grading for the hard -surfaced area will not be required as the pad is a relatively flat and sand -covered. 5. The total lot disturbance will be 29.2% (40% maximum permitted). 6. The structural lot coverage proposed is 14.2% (20% maximum permitted) and the total lot coverage proposed is 29.2% (35% maximum permitted). 7. The existing building pad coverage for the residential pad is 68.4%. Coverage on the second building pad will be 60.6%. Total building pad coverage for both building pads will be 65.5%. 8. Other issues that the Planning Commission discussed were: the retention of existing topography, plants and animals, natural features; landscape screening, views, and the imposition of conditions when necessary to ensure that noise does not constitute a nuisance to surrounding properties. 9. The Planning Commission found that the project will not have a significant effect on the environment and adopted a Negative Declaration in accordance with the California Environmental Quality Act.

THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS: Section 1. Applications were duly filed by Mrs. Frances A. Johnson with respect to real property located at 4 Buckboard Lane, Rolling Hills (Lot 34-A-GF) requesting a Variance to permit encroachment into the side yard setback to construct a bedroom addition and requesting a Conditional Use Permit for the construction of a hard -surfaced area to be used for recreational purposes at an existing single family residence. During the hearing process, the hard -surfaced area to be used for recreational purposes was reduced in size from 5,361 square feet to 3,096 square feet. Section 2. The Planning Commission conducted a duly noticed public hearing to consider the applications on June 20, 1995 and July 18, 1995, and at a field trip visit on July 8, 1995. Section 3. On May 24, 1995, Planning staff prepared an initial study for the project. The initial study found that the project would not have a significant effect on the environment. The Negative Declaration was prepared and was circulated to the applicant and other interested parties in accordance with State of California CEQA Guidelines. The public notice of the Planning Commission's intent to recommend approval of the Negative Declaration was published on May 27, 1995. Copies of the Negative Declaration were sent to adjacent cities and other government agencies. No comments on the Negative Declaration were received. The Planning Commission finds that the project will not have a significant effect on the environment and adopted a Negative Declaration in accordance with the California Environmental Quality Act. Section 4. Sections 17.38.010 through 17.38.050 of the Rolling Hills Municipal Code permit approval of a Variance from the standards and requirements of the Zoning Ordinance when exceptional or extraordinary circumstances applicable to the property and not applicable to other similar properties in the same zone prevent the owner from making use of a parcel of property to the same extent enjoyed by similar properties in the same vicinity. Section 17.16.120(B) requires a side yard setback for every residential parcel in the RA-S-2 zone to be thirty-five (35) feet. The applicant is requesting to construct a 387 square foot bedroom addition which will encroach a maximum of fifteen (15) feet RESOLUTION NO. 95-11 PAGE 1 OF 6 • • into the thirty-five (35) foot west side yard setback. With respect to this request for a Variance, the Planning Commission finds as follows: A. There are no exceptional and extraordinary circumstances and conditions applicable to the property or to the intended use that do not apply generally to the other property in the same vicinity and zone. The variance is not necessary because the building pad coverage for this project on the upper residential pad would be 72.7% which the Commission finds excessive and exceeds the building pad coverage of most properties in the vicinity so that the proposed expansion is not appropriate for the property. B. The Variance is not necessary for the preservation and enjoyment of a substantial property right possessed by other property in the same vicinity and zone, but which is denied to the property in question because both the garage and pool encroach into the front yard setback, a portion of the residence encroaches into the east side yard setback and additional encroachments would exacerbate the amount of residential structure within setback areas. C. The granting of the Variance will be materially detrimental to the public welfare or injurious to the property or improvements in such vicinity and zone in which the property is located because the proposed project does not minimize structural coverage on the pad, leaves little open space between property lines, would further restrict vehicular and pedestrian traffic, would result in further overdevelopment of the building pad and far exceeds the recommended coverage of 30%. This would make the proposed bedroom addition more visually prominent on the building pad than appropriate for the existing development pattern of the City. Section 5. Based upon the foregoing findings, the Planning Commission hereby denies the request for a Variance approval for the construction of a 387 square foot bedroom addition into the west side yard setback in Zoning Case No. 526. Section 6. Section 17.16.210(A)(7) of the Rolling Hills Municipal Code allows for the construction of a hard -surfaced area to be used for recreational purposes provided a Conditional Use Permit for such use is approved by the Rolling Hills Planning Commission. Section 7. With respect to the request for a Conditional Use Permit for a 3,096 square foot hard -surfaced area to be used for recreational purposes, the Planning Commission makes the following findings: A. The granting of a Conditional Use Permit for a hard -surfaced area to be used for recreational purposes would be consistent with the purposes and objectives of the Zoning Ordinance and General Plan and will be desirable for the public convenience and welfare because the use is consistent with similar recreational uses RESOLUTION NO. 95-11 PAGE 2 OF 6 • • in the community and the court will be located in an area of the property where such use will be the least intrusive to surrounding properties. B. The granting of the Conditional Use Permit would be consistent with the purposes and objectives of the Zoning Ordinance and General Plan because the hard -surfaced area to be used for recreational purposes will comply with the low profile residential development pattern of the community and is located on a 2.1 acre parcel of property that is adequate in size, shape and topography to accommodate such use. C. The granting of a Conditional Use Permit would be consistent with the purposes and objectives of the Zoning Ordinance and General Plan because the hard -surfaced area to be used for recreational purposes will not impact the view or the privacy of neighbors. The hard -surfaced area will not require grading, will replace a sand -covered play area and will be screened by landscaping. Section 8. Based upon the foregoing findings, the Planning Commission hereby approves the request for a Conditional Use Permit in Zoning Case No. 526 for a proposed 3,096 square foot hard -surfaced area to be used for recreational purposes, as shown on the Development Plan dated August 1, 1995, and marked REVISED Exhibit A, subject to the conditions specified in Section 9. Section 9. The Conditional Use Permit for the construction of a 3,096 square foot hard -surfaced area to be used for recreational purposes approved in Section 8 as indicated on the Development Plan attached hereto and incorporated herein as REVISED Exhibit A dated August 1, 1995, is subject to the following conditions: A. The Conditional Use Permit approval shall expire within one year from the effective date of approval as defined in Section 17.42.070(A). B. It is declared and made a condition of the Conditional Use Permit approval, that if any conditions thereof are violated, the Permit shall be suspended and the privileges granted thereunder shall lapse; provided that the applicant has been given written notice to cease such violation and has failed to do so for a period of thirty (30) days. C. All requirements of the Building and Construction Ordinance, the Zoning Ordinance, and of the zone in which the subject property is located must be complied with unless otherwise approved by Variance. D. The lot shall be developed and maintained in substantial conformance with the site plan on file marked REVISED Exhibit A dated August 1, 1995, except as otherwise provided in these conditions. RESOLUTION NO. 95-11 PAGE 3 OF 6 • • E. The property on which the project is located shall contain an area of sufficient size to also provide an area meeting all standards for a stable and corral with vehicular access thereto. F. Structural lot coverage shall not exceed 9,663 square feet or 14.2% and total lot coverage of structures and paved areas shall not exceed 19,849 square feet or 29.2%. G. Grading shall not be required for the construction of the hard -surfaced area to be used for recreational purposes. H. Any preparations of soil for the hard -surfaced area to be used for recreational purposes shall preserve the existing topography, flora, and natural features to the greatest extent possible. I. A drainage system approved by the City Engineer shall be incorporated into the overall plan of the hard -surfaced area to be used for recreational purposes and the surrounding landscaped areas. J. Landscape screening shall continue to be maintained so as not to obstruct views of neighboring properties but, to obscure the hard -surfaced area to be used for recreational purposes. K. Lighting for the hard -surfaced area to be used for recreational purposes shall not be permitted. L. All retaining walls incorporated into the court shall not be greater than four feet in height at any point. Exposed exterior retaining walls shall not be permitted. M. Any screening fences for the hard -surfaced area to be used for recreational purposes shall be landscaped and not exceed 8 feet in height. N. No structures (i.e., skateboard ramps, slides, etc.) shall be incorporated in the hard -surfaced area to be used for recreational purposes. O. Noise from the hard -surfaced area use shall not create a nuisance to owners of surrounding properties. P. Review and approval of a site drainage plan by the City Engineer shall be obtained for the hard -surfaced area to be used for recreational purposes. Q. A plan that conforms to the development plan as approved by the Planning Commission must be submitted to the Rolling Hills Planning Department staff for their review prior to the submittal of an applicable site drainage plan to the County of Los Angeles for plan check. RESOLUTION NO. 95-11 PAGE 4 OF 6 • • R. The project must be reviewed and approved by the Rolling Hills Community Association Architectural Review Committee prior to approval of the drainage plan. S. The working drawings submitted to the County Department of Building and Safety for site drainage plan review must conform to the development plan described at the beginning of this section (Section 9). T. The applicant shall execute an Affidavit of Acceptance of all conditions of this Conditional Use Permit pursuant to Section 17.42.060, or the approval shall not be effective. U. All conditions of this Conditional Use Permit approval must be complied with prior to approval of the site drainage plan by the County of Los Angeles.

The existing house and garage was constructed in 1965 along with retaining walls and a swimming pool. In 1979, a remodel of a master bedroom and bath included an addition of 150 square feet. 4. Grading will not be required for the residential addition. Grading for the hard - surfaced area will not be required as it is a relatively flat sand -covered pad. 5. The total lot disturbance will be 33.1%. (40% maximum permitted). 6. The structural lot coverage proposed is 18.1% (20% maximum permitted) and the total lot coverage proposed is 33.1% (35% maximum permitted). Staff included the hard -surfaced area in structural lot coverage calculations. 7. The existing building pad coverage for the residential pad is 68.4% and the proposed building pad coverage will be 72.7%. Coverage on the second building pad will be 93.6% for the future stable. Total building pad coverage for both building pads will be 83.5%. Staff included the hard -surfaced area in building pad coverage calculations. The City has a policy that addresses coverage of an identified "Existing Buildable Area" as coverage that is based upon the calculation of the "footprint" square footage of the residence, garage, stable (barn), and other accessory structures proposed and/or developed on said "buildable area." 8. Other issues that the Planning Commission may wish to discuss are: the retention of existing topography, plants and -animals, natural features; landscape screening, views, and the imposition of conditions when necessary to ensure that noise does not constitute a nuisance to surrounding properties. 9.

VARIANCE TO PERMIT ENCROACHMENT INTO THE EAST SIDE YARD SETBACK FOR A RETAINING WALL, AND REQUEST FOR A CONDITIONAL USE PERMIT TO CONSTRUCT A 5,361 SQUARE FOOT HARD -SURFACED AREA TO BE USED FOR RECREATIONAL PURPOSES. ENVIRONMENTAL SETTING Item 38. Description of project site. The project site is a large 2.1 acre hillside parcel that contains a residence, detached garage and pool on a flat pad. There is also an existing sand covered pad on the hillside 15 feet below the residence that is relatively flat. The existing residence is located near the south side of the property. Native brush grows on the steep slope at the rear of the lot. Landscaped lawns, shrubs and trees surround the existing residence, with native plants, grasses, shrubs, and trees beyond the residential area. Native birds and animals frequent the area such as sparrows, crows, raccoons, possum, skunks, gophers and an occasional fox. s: Printed on Recycled Paper. • • Page 2 Item 39. Description of surrounding properties. The site is located within a one unit per 2-acre designation and is surrounded by similar development of the one-story ranch style with agricultural outbuildings. As described in Paragraph 38, native birds and animals frequent the area. 000 The following analysis is a description of the findings contained in the Environmental Information and Checklist Form which preceded this page. A detailed discussion of all potential environmental impacts checked "Yes" or "Maybe" is provided, along with appropriate mitigation measures. ENVIRONMENTAL IMPACTS Item 40. Earth. a-d. Although approval of the project will not result in unstable earth conditions or in changes in geologic substructures, it should be noted that portions of the City exhibit unstable earth conditions, including active landslides and soil creep. The Land Use Element of the General Plan establishes a Landslide Hazard Overlay to carefully regulate development in unstable areas. This property is not within a mapped active landslide area. Grading, excessive irrigation, and/or increased septic tank discharge in unstable areas may trigger additional slope failure. Because the City is located in seismically active southern California, additional development will be exposed to potential groundshaking in the event of an earthquake. The Palos Verdes fault, considered potentially active, is located approximately one mile northeast of the City. Although approval of the project will result in disruptions, displacements, compaction, or overcovering of the soil during future construction, these will occur in order to prepare a hard -surfaced area to be used for recreational purposes. Any displacement and recompaction of the soil will be required to conform with local ordinances and engineering practices requiring balanced cut and fill and should not cause a significant environmental impact. e-g. Also, during future construction, there will be removal of natural vegetative cover and sand surface, potentially causing an increase in soil erosion by wind action or storm runoff. This reduction of vegetative cover and porous sand surface and the increased runoff associated with development of a hard - surfaced area to be used for recreational purposes may cause a slight increase in the soil deposition, siltation, or erosion in or near the ocean. As development is limited to a residential addition of 387 square feet and a • • Page 3 5,361 square foot hard -surfaced area to be used for recreational purposes, related erosion impacts will be less than significant. Item 41. Air a-c. The proposed project will not increase residential development. While the development will generate slight increases in vehicle trips and objectionable odors during construction, the resultant impact on air quality will be less than significant. Item 42. Water a. Future development of a bedroom addition and a hard -surfaced area to be used for recreational purposes on the 2.1 acre parcel will not alter fresh or marine water currents. b. The proposed project may alter drainage patterns, increase runoff and reduce water absorption by the placement of structures, the introduction of impervious surface materials and irrigation systems. However, due to the nominal increase in development proposed and permitted by the General Plan, the impacts are not expected to be substantial. c. No major floodplains exist in the City. Flood waters generally flow through the canyon areas. The General Plan does not permit development in the canyons, and so changes in the course or flow of floodwaters is not anticipated. d. No water bodies are located in the project area. Future development in the project area is not expected to result in change in the amount of any water bodies located in the vicinity. 1• No major floodplains exist in the City, and development is not permitted in the canyon areas most likely to be affected by flooding. No open bodies of water occur within the City, thus no such hazard exists. The project is located high enough and far enough away from the ocean that tsunami hazards do not exist. Some additional discharge into surface waters downstream may occur due to sheet water flow from the proposed hard -surfaced area to be used for recreational purposes. Item 43. Plant Life a-d. Any additional development within the City will reduce the amount of native vegetation which will be replaced, in some instances, by non-native species. • • Page 4 But, due to the limited growth proposed, this impact will be less than significant. In addition, the General Plan and Zoning Code set forth policies which encourage the retention and use of native drought tolerant vegetation in landscaping. No known rare and endangered species of plants exist in the City. Item 45. Noise a. Future development of a bedroom addition will be less than significant. Future development of a hard -surfaced area to be used for recreational purposes may cause an increase in existing noise levels as children and/or adults play ball, skate, and engage in recreational activities on the surface. b. Future development of a hard -surfaced area to be used for recreational purposes will not expose people to severe noise levels. Item 44. Animal Life a. As further development occurs in Rolling Hills, the natural habitat of the area will be slightly reduced. But, the impact of the current proposal is expected to be less than significant. b. Large lot, estate density development along with a bedroom addition, and a hard -surfaced area to be used for recreational purposes for this project provides the opportunity to retain substantial amounts of existing habitat. The only animal listed by the Federal Government is the Palos Verdes Blue, a butterfly which had not been seen in the Rolling Hills area since May, 1986. In 1994, the Palos Verdes Blue was seen at the nearby San Pedro Fuel Depot Station where its habitat is being restored. Several other animals do occur, however, that are considered as candidates for protection by either the Federal Government or the State Government. Recently, the California gnatcatcher was added to the list of endangered species and, in a recent census, pairs were located in the adjacent City of Rancho Palos Verdes. Other target species for the Rancho Palos Verdes Peninsula Area that are being studied by the State of California Department of Fish and Game are the Cactus Wren and the Coast Horned Lizard. The impact of the proposed future development of a bedroom addition and a hard -surfaced area to be used for recreational purposes will be less than significant. Item 46. Light and Glare Residential building materials are carefully regulated by Zoning Ordinance and the Community Association. Buildings are limited to one story in height. Light and glare impacts therefore are expected to be less than significant. • • Page 5 Item 52. Transportation/Circulation a. The incremental increase of a bedroom addition and a hard -surfaced area to be used for recreational purposes will not generate more daily vehicle trips. This is considered less than significant. Item 59. Cultural Resources a. While prior tilling and dry farming disrupted potential remains, the applicant does not propose to do any grading. *0 On the basis of this initial evaluation: (check one) ® I find the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION has been prepared. I find the project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. Date Mav 24.1995 By: gvek LOLA M.

VARIANCE TO PERMIT ENCROACHMENT INTO THE EAST SIDE YARD SETBACK FOR A RETAINING WALL, AND REQUEST FOR A CONDITIONAL USE PERMIT TO CONSTRUCT A 5,361 SQUARE FOOT HARD -SURFACED AREA TO BE USED FOR RECREATIONAL PURPOSES. ENVIRONMENTAL SETTING Item 38. Description of project site. The project site is a large 2.1 acre hillside parcel that contains a residence, detached garage and pool on a flat pad. There is also an existing sand covered pad on the hillside 15 feet below the residence that is relatively flat. The existing residence is located near the south side of the property. Native brush grows on the steep slope at the rear of the lot. Landscaped lawns, shrubs and trees surround the existing residence, with native plants, grasses, shrubs, and trees beyond the residential area. Native birds and animals frequent the area such as sparrows, crows, raccoons, possum, skunks, gophers and an occasional fox. Panted on Recycled Paper. • Page 2 Item 39. Description of surrounding properties. The site is located within a one unit per 2-acre designation and is surrounded by similar development of the one-story ranch style with agricultural outbuildings. As described in Paragraph 38, native birds and animals frequent the area. 000 The following analysis is a description of the findings contained in the Environmental Information and Checklist Form which preceded this page. A detailed discussion of all potential environmental impacts checked "Yes" or "Maybe" is provided, along with appropriate mitigation measures. ENVIRONMENTAL IMPACTS Item 40. Earth. a-d. Although approval of the project will not result in unstable earth conditions or in changes in geologic substructures, it should be noted that portions of the City exhibit unstable earth conditions, including active landslides and soil creep. The Land Use Element of the General Plan establishes a Landslide Hazard Overlay to carefully regulate development in unstable areas. This property is not within a mapped active landslide area. Grading, excessive irrigation, and/or increased septic tank discharge in unstable areas may trigger additional slope failure. Because the City is located in seismically active southern California, additional development will be exposed to potential groundshaking in the event of an earthquake. The Palos Verdes fault, considered potentially active, is located approximately one mile northeast of the City. Although approval of the project will result in disruptions, displacements, compaction, or overcovering of the soil during future construction, these will occur in order to prepare a hard -surfaced area to be used for recreational purposes. Any displacement and recompaction of the soil will be required to conform with local ordinances and engineering practices requiring balanced cut and fill and should not cause a significant environmental impact. e-g. Also, during future construction, there will be removal of natural vegetative cover and sand surface, potentially causing an increase in soil erosion by wind action or storm runoff. This reduction of vegetative cover and porous sand surface and the increased runoff associated with development of a hard - surfaced area to be used for recreational purposes may cause a slight increase in the soil deposition, siltation, or erosion in or near the ocean. As development is limited to a residential addition of 387 square feet and a Page 3 5,361 square foot hard -surfaced area to be used for recreational purposes, related erosion impacts will be less than significant. Item 41. Air a-c. The proposed project will not increase residential development. While the development will generate slight increases in vehicle trips and objectionable odors during construction, the resultant impact on air quality will be less than significant. Item 42. Water a. Future development of a bedroom addition and a hard -surfaced area to be used for recreational purposes on the 2.1 acre parcel will not alter fresh or marine water currents. b. The proposed project may alter drainage patterns, increase runoff and reduce water absorption by the placement of structures, the introduction of impervious surface materials and irrigation systems. However, due to the nominal increase in development proposed and permitted by the General Plan, the impacts are not expected to be substantial. c. No major floodplains exist in the City. Flood waters generally flow through the canyon areas. The General Plan does not permit development in the canyons, and so changes in the course or flow of floodwaters is not anticipated. d. No water bodies are located in the project area. Future development in the project area is not expected to result in change in the amount of any water bodies located in the vicinity. l• No major floodplains exist in the City, and development is not permitted in the canyon areas most likely to be affected by flooding. No open bodies of water occur within the City, thus no such hazard exists. The project is located high enough and far enough away from the ocean that tsunami hazards do not exist. Some additional discharge into surface waters downstream may occur due to sheet water flow from the proposed hard -surfaced area to be used for recreational purposes. Item 43. Plant Life a-d. Any additional development within the City will reduce the amount of native vegetation which will be replaced, in some instances, by non-native species. • • • Page 4 But, due to the limited growth proposed, this impact will be less than significant. In addition, the General Plan and Zoning Code set forth policies which encourage the retention and use of native drought tolerant vegetation in landscaping. No known rare and endangered species of plants exist in the City. Item 45. Noise a. Future development of a bedroom addition will be less than significant. Future development of a hard -surfaced area to be used for recreational purposes may cause an increase in existing noise levels as children and/or adults play ball, skate, and engage in recreational activities on the surface. b. Future development of a hard -surfaced area to be used for recreational purposes will not expose people to severe noise levels. Item 44. Animal Life a. As further development occurs in Rolling Hills, the natural habitat of the area will be slightly reduced. But, the impact of the current proposal is expected to be less than significant. b. Large lot, estate density development along with a bedroom addition, and a hard -surfaced area to be used for recreational purposes for this project provides the opportunity to retain substantial amounts of existing habitat. The only animal listed by the Federal Government is the Palos Verdes Blue, a butterfly which had not been seen in the Rolling Hills area since May, 1986. In 1994, the Palos Verdes Blue was seen at the nearby San Pedro Fuel Depot Station where its habitat is being restored. Several other animals do occur, however, that are considered as candidates for protection by either the Federal Government or the State Government. Recently, the California gnatcatcher was added to the list of endangered species and, in a recent census, pairs were located in the adjacent City of Rancho Palos Verdes. Other target species for the Rancho Palos Verdes Peninsula Area that are being studied by the State of California Department of Fish and Game are the Cactus Wren and the Coast Horned Lizard. The impact of the proposed future development of a bedroom addition and a hard -surfaced area to be used for recreational purposes will be less than significant. Item 46. Light and Glare Residential building materials are carefully regulated by Zoning Ordinance and the Community Association. Buildings are limited to one story in height. Light and glare impacts therefore are expected to be less than significant. • • Page 5 Item 52. Transportation/Circulation a. The incremental increase of a bedroom addition and a hard -surfaced area to be used for recreational purposes will not generate more daily vehicle trips. This is considered less than significant. Item 59. Cultural Resources a. While prior tilling and dry farming disrupted potential remains, the applicant does not propose to do any grading. 000 On the basis of this initial evaluation: (check one) • I find the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION has been prepared. I find the project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. Date Mav 24,1995 By: LOLA M.
