G:\WPDOCS\Env Asses\BartonCklst.WPD 0 Environmental Factors Potentially Affected: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. Aesthetics Agriculture Resources Air Quality Biological Resources Cultural Resources Geology and Soils Hazards & Hazardous Materials Hydrology and Water Quality Land Use Planning Mineral Resources Noise Population and Housing Determination On the basis of this initial evaluation: Public Services Recreation Transportation/Traffic Utilities and Service Systems Mandatory Findings I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared 4 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 revisions in the project have been made by or agreed to by the applicant. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact' or "potentially significant unless mitigated" on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 21 has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. El I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. C-c �C6&L) I IyI Signature Uate CITY OF LA QUINTA ante ame G:\WPDOCS\Env Asses\13artonCk1st.WPD 2 9 Evaluation of Environmental Impacts: • 11 A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the reference information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis). 2) All answers must take account of the whole action involved, including off -site as well as on -site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVIII, "Earlier Analysis," may be cross-referenced). 5) Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). Earlier analysis are discussed in Section XVIII at the end of the checklist. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) The analysis of each issue should identify: a) the significance criteria or threshold used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance G:\WPDOCS\Env Asses\BartonCklst.WPD 3 `J • Issues (and Supporting Information Sources): Would the proposal result in potential impacts involving: I.

G:\WPDOCS\Env Asses\BartonCklst.WPD 12 C Revised Addendum for Environmental Assessment 2001-417 for Tentative Tract Map 30092 Introduction This Environmental Assessment has been prepared to address changes made to Tentative Tract Map 30092. The original application was reviewed under EA 2001- 417, an environmental assessment to supplement EA 2001-408 prepared for General Plan Amendment 2001-074 and Zone Change 2001-098 (City Council Resolution 2001-34). Since the original approval and environmental review, the applicant has increased the number of residential lots from 97 to 130. II. c) The proposed parcel is not currently under Williamson Act contract. Development of the site will result in the loss of land available for agriculture. Residential subdivisions are being developed to the north of the site and the project area is an isolated parcel. Lands to the south and east continue to be farmed. The loss of this site for agriculture is not expected to be significant based on the conclusion of this assessment and EA 2001-408. III. a), c) & d) Air quality in the Coachella Valley and the City is primarily affected by vehicular emissions. The development of this project could generate up to 1,300 average daily trips'. These trips could generate the following emissions. The Table below also includes the SCAQMD thresholds of significance for each potential pollutant.

G:\WPDOCS\Env Asses\BartonRevAdd.WPD 1 0 The Coachella Valley is a non -attainment area for PM10 (particulate matter of 10 microns or smaller). The non -attainment status results in potentially significant impacts associated with new development, particularly during the construction of new projects. In order to control PM10, the City has imposed standards and requirements on development to control dust. In addition to these standards, SCAQMD suggests mitigation for PM10, which are integrated into the following mitigation measures: 1. No earth moving activity shall be undertaken without the review and approval of a PM10 Management Plan. 2. Construction equipment shall be properly maintained and serviced to minimize exhaust emissions. 3. Existing power sources should be utilized where feasible via temporary power poles to avoid on -site power generation. 4. Construction personnel shall be informed of ride sharing and transit opportunities. 5. Cut and fill quantities will be balanced on site, unless otherwise allowed by the City Engineer. 6. Any piece of land to be graded shall be pre -watered to a depth of three feet prior to the onset of grading activities. 7. Watering of any portion of the site or other soil stabilization method shall be employed on an ongoing basis after the initiation of any grading activity on the site. Any portion of the site that is actively being graded shall be watered regularly to ensure that a crust is formed on the ground surface, and shall be watered at the end of each work day. 8. All disturbed areas shall be treated to prevent erosion until the site is constructed upon. Pad sites which are to remain undeveloped shall be seeded with either a desert wildflower mix, grass seed or chemical stabilizers. 9. Landscaped areas shall be installed as soon as possible to reduce the potential for wind erosion. 10. SCAQMD Rule 403 shall be adhered to, insuring the clean up of construction -related dirt on approach routes to the site. 11. All grading activities shall be suspended during first and second sta, ozone episodes or when winds exceed 25 miles per hour. G:\WPDOCS\Env Asses\BanonRevAdd.WPD 2 0 0 With the implementation of these mitigation measures, the impacts to air quality from the proposed project will not be significant. IV. a) Biological resource analysis has not been performed because the site has been actively used for farm activities and therefore is not likely to be a valuable habitat for native species. The land is not in an area of concern for known sensitive species and is outside the boundary of the Coachella Valley Fringe - toed Lizard Habitat Conservation Plan. The changes associated with the application will not change the potential impacts to biological resources. Impacts from development are not expected to be significant. V. a) & b) Cultural resource surveys were conducted for the subject property. The survey found that no significant resources occur on the site. V. c) The site has been previously assessed for paleontologic resources'. The area was within the historic lakebed of ancient Lake Cahuilla, but no vertebrate remains have been located. The mollusks found are abundant in this area, and do not represent a significant resource. As such, the on -site investigation and report found that the impacts on paleontologic resources are less than significant, and that no further analysis of the site is necessary. VI. a) i) & ii) The site is not located in any Earthquake Fault zones as designated by the State and is mapped in the Ground Shaking Zone IV. To ensure structures can withstand damage from earthquakes, compliance with the Geotechnical Investigation Report by Sladden Engineering dated February 9, 2001, and any other site specific soil analysis required by the City Engineer prior to issuance of grading permits shall be required. This requirement will ensure that impacts from ground failure are reduced to a less than significant level. VI. a) iii) This site may be subject to liquefaction due to groundwater being found within 25 to 30 feet requiring "remedial grading including overexcavation and recompaction." (Sladden Report). The modification of the application does not 2 5 Him orical/Archaeolopical Resources Survey, prepared by CRM Tech, October, 2000; Phase I Archaeolopical/Historical Survey, prepared by James Brock, MA, RPA dated April 2001. Paleontological Resources Assessment Repon, prepared by CRM Tech, October 2000. Environmental Assessments prepared for the County of Riverside. These include: PP15672, Fast Track �98.39; TTM 29316 & 29317; Environmental Assessment No. 37276, Amd. No 1. These analyses cover 200 of the 280 acres proposed for this project. G:\WPDOCS\Env Asses\BartonRevAdd.WPD 3 affect this potential impact, and requires equivalent mitigation as the previous application. To develop the site, the following mitigation measure shall be implemented: 1. Grading activities and structure development shall comply with the recommendations of the Geotechnical Investigation Report prepared by Sladden Engineering for TTM 30092 including over -excavation, and other methods known to reduce the potential for liquefaction impacts on residential structures. VIII. b) Domestic water is provided by the Coachella Valley Water District, which extracts groundwater from a number of wells in the Lower Thermal sub -basin. Development of the site will replace the use of canal water for crop irrigation and may represent a positive impact insofar as water usage may be reduced when agricultural irrigation no longer occurs on the site. The proposed amendment to the project will increase water usage over that previously analyzed. Stormwater generated by development will be retained on -site which will encourage percolation and groundwater recharge. The proposed alteration to the project does not change the City's requirements for on -site retention. Additionally, City Ordinances require water conserving plumbing fixtures and landscaping. These standards will reduce potential impacts to a less than significant level. VIII. c)-e) Site development of buildings and parking areas will create impermeable surfaces creating drainage pattern changes. The project site is located in a C Flood Zone. The project is required to meet the City's standards for retention of the 100-year storm on -site. The revised drainage plan, prepared by Hacker Engineering, has been reviewed by the City Engineer for compliance with Section 1 3.24.120 (Drainage) of the Subdivision Ordinance. Tract conditions are recommended to ensure compliance assuring the flood control system is less than significant. XI. a) The development of the area will result in increased noise levels, but these are not expected to be significant, given that the ambient noise level is, and will continue to be low. Development on any portion of the site will include landscaping, berms and walls which will further attenuate sound in the area as required by Noise Impact Report prepared by P.A. Penardi and Associates dated April 4, 2001. Amendment of the application will not change the potential impacts associated with noise. The impacts from noise are therefore not expected to be significant. G:\WPDOCS\Env Ass es\eanonRevAdd.WPD 4 0 0 XIII. a) The proposed development will have a direct impact on public services and will be served by the County Sheriff and Fire Department, acting under City contract. Site development will generate property tax which will offset the costs of added police and fire services. The project area will continue to pay the mandated school fees as development occurs. These fees mitigate the students generated, and offset the impacts to schools. The collection of property tax, and the generation of sales tax from these residents' disposable income, will generate revenues to the City to offset the added costs associated with the provision of municipal services. Builders within the project area will be required to participate in the City's Impact Fee Program, which helps to offset roadway improvement costs. The amendment of the application will not significantly change the impacts to public services. Increases in population resulting from the increased number of lots will be offset by increased revenues in property and sales tax. Site development is not expected to have a significant impact on municipal services or facilities. XV. a) The Village of the Palms project determined traffic impacts for development would be less than significant". Under EA 2001-408 (City Council Resolution No. 2001-34) it was determined that a traffic study would not be required, provided the sites were developed to comply with the LDR General Plan designation and Impact Mitigation Fees were paid. The amendment of the application will add only 330 trips per day to the regional road system. The application, as amended, still falls within the Low Density Residential land use category. The implementation of these mitigation measures will reduce the potential impacts to the circulation system to a less than significant level. XVI. a)-f) The buildout of the site will require service from utility providers. The overall impacts on these services is not expected to be significant, insofar as these suppliers will charge the residents for their services, and provide improvements to these services as needed. In addition, connection fees will be required at construction of any project. These fees and charges will mitigate the potential impacts to a less than significant level.
