The resubmitted bio-analysis is much better, thank you. However, I still unfortunately have a couple additional changes to the document. Please revise the Table (Summary of Vegetation Resource Impacts) on Pg. 3 and also Fig. "A" such that it refers to the Coastal Sage/Chaparral Mix as "Unoccupied," this is to match what is being stated in the body of the text. Also, revise Section 7 (HMP Compliance) on Pg. 3 to also discuss the mitigation for Unoccupied Coastal Sage Scrub and Disturbed Lands in accordance with Table-11. Since none of the project site is being preserved, the acreage calculations for mitigation fees must account for the whole site (not the impacted). For example, you list 4.35 acres of "impacted" AG to be mitigated. This should actually be listed as 4.99 acres since none of it will be preserved in an open space system or some other means of preservation. This is also the same for the unoccupied CSS and disturbed lands. Please call me if you have any questions regarding this email.

August 14. 2002; This report was updated March 18.2003. Both reports were prepared , by Affinis Environmental Services. The objective of this analysis is to assess current site " vegetation and to determine what avian species are present on the site. Based on our , " ' findings, revised plant associations and impacted area quahtities are provided. The proposed project is also assessed in terms of Habitat Management Plan (HMP) compliance.

The analysis began with a review of both Affinis letter reports.; Five Affinis 2002 ;report elements were re-assessed, mcluding: 1) Figure 3, Biological, Resources (map), 2) Plant Association text, 3) Rare and \, Endangered or Sensitive Species disoission, 4) Appendix 1, Plant Species Observed, and 5) Appendix 2, Sensitive Plant Species Potentially Occurring On -site.

The Biological Resources \; map (Figure 3) from the Affinis 2002 report was, used as the Planning Systems field work base map. All accessible areas of the site1 were traversed, including dense brush areas., .The site was surveyed to identify plant associations and sensitive plant species present. 1530 FARADAY AVENUE • SUITE 100 • CARLSBAD, CA 92008 • (760) 931-0780 • FAX (760) 931-5744 •info@planningsystems.net On August 31,2006, Seth Schulberg, Wildlife Biologist for Planning Systems conducted an avian survey of the site to determine if the Affinis findings were still representative of the avifauna present on the site. All accessible areas of the site were walked and binoculars were used to observe inaccessible portions of the property. Avian identifications were made based on visual and audio cues. Additional effort was undertaken to assess the quality of the Coastal Sage Scrub habitat onsite to determine its suitability for use by the California Gnatcatcher (Polioptila californica californica). Results 1) Vegetation Mapping Planning Systems concurs with the Af finis conclusions on plant association boundary lines identified on Figure 3, Biological Resources (map), Af finis 2002. Planning Systems also concurs with the mapped associations on the southern slopes of the property, LS for Landscaped, and CSS/MC for Coastal Sage Scrub / Mixed Chaparral, and on the slope bordering La Costa Avenue on the north edge of the property, identified as NNG / LS for Non-native grassland / Landscaped. Thus, it is concluded that the boundaries of the plant associations have not changed from the Affinis analyses. However, Planning Systems concludes that the Affinis designation of D/R, Disturbed/Ruderal for the plant association occurring on the graded pad area, should more appropriately be considered Annual Grassland. In our opinion a majority of the vegetation occurring on the pad is comprised of exotic species such as Brome grasses, Wild oat, Tocalote, Black Mustard, and Perennial Mustard as wells as natives such as Fascicled tarweed and Telegraph weed. This plant association is described in the Carlsbad HMP as Annual Grassland, (see the attached Figure A - Biological Resources Confirmation Analysis). 2) Plant Association Text In "Section C. Results" of the 2002 Affinis report, plant associations are described. Planning Systems agrees with these findings except for the identification of "Disturbed/Ruderal" which Planning Systems views as Annual Grassland, as stated above. 3) Rare and Endangered or Sensitive Species Section C.4 of the Affinis report states "No rare, endangered, or threatened plant species were observed on the site or are expected to occur". Planning Systems also did not observe sensitive plant species on the property, but it should be noted Calso Biological Confirmation Analysis 2 8/21/06 that we did not visit tine site during the time of year when certain sensitive species are most visible. 4) Appendix 1. Plant Species Observed All species documented in the Affinis 2002 report were observed occurring on(- site. Planning Systems also observed additional plant species occurring on-site, mostly herbaceous ones, typical associates of the identified habitats. 5) Appendix 2, Sensitive Plant Species Potentially Occurring On-site The target group of sensitive plant species sought by Affinis is in our opinion, adequate. However, as previously stated, Planning Systems can not verify absence of certain species because of the time of year of our field work. 6) Summary of Vegetation Resource Impacts Vegetation Resources Identified Plant Association Annual (non-native) grassland (AG) Annual (non-native) grassland/Landscaped (AG) Ornamental Landscape (LS) Coastal Sage/Chaparral Mix (CS/CM) TOTALS Area (Acres) 4.39 0.60 2.07 1.12 8.18 Impacted (Acres) 4.35 0.60 1.84 0.23 7.02 % Impacted 99.1% 100.0% 88.8% 20.5% 85.8% 7) HMP Compliance The subject property is not identified as a hardline preserve, link or any other aspect of a preserve system. The property is not known to be ocaimgdby the California gnatcatcher. Mitigation will be required for impacts tdL4.9jjftcres of AG through pament of a mitigation fee at a 0.5:1 ratio per Table 11 Mitigation Rhtios for ImpactstcL Habitats. The project is consistent with the adopted HMPT) s"" 8) Avifauna Present Planning Systems' biologists conducted a survey of the site for the California gnatcatcher.~ Overall the site is highly disturbed with the majority of the site covered in non-native vegetation. Affinis reported that little wildlife was observed on the site. Planning Systems concurs with this conclusion and agrees that conditions have not changed significantly since the Affinis report was prepared. Seven avian species were detected onsite as listed in the table below. Calso Biological Confirmation Analysis 8/21/06 Avian Species Detected Family Columbidae Emberizidae Fringillidae Mimidae Phasianidae Common Name Mourning Dove California towhee Song Sparrow Chipping Sparrow House Finch Northern Mockingbird California Quail Scientific Name Zenaida macroura Pipilo crissalis Melospiza melodia Spizella passerine Carpodacus mexicanus Mimus polyglottus Callipepla californica californica None of the above identified bird species are protected by local, state or federal regulations. No raptors were observed overflying the site and no raptor nests were observed in any of the trees on the site. No California gnatcatchers were observed on the site and no audible indications of California gnatcatchers were detected. The small area and lower quality of coastal sage scrub on the site would not be considered consistent with typical gnatcatcher occupation. 9)Conclusions Planning Systems' botanical field survey of the site in August 2006 concludes that no significant changes to the vegetation on the site have occurred with the exception that the plant community identified as Disturbed/Ruderal (DR) by Affinis has been more appropriately identified as Annual grassland (AG). No other differences from the 2002- 03 botanical surveys were observed. Planning Systems' avifauna survey of the site in August 2006 also concludes that no significant changes to the avifauna found onsite have occurred. Though several additional bird species were observed, none are protected species, and no California gnatcatchers occupy the site, which is consistent with the conclusion originally reported in the Affinis 2002 protocol survey.
