It comprises 337 acres of 'european annual grassland and contains iow-grade habitat for the Mission Blue and Callippe Silvers-pot butterflies (See Figures 2-04 Ownersh'ip: The South Slope Project is owned byVisitacion Associates and is under .the planning responsibility of W. W. Dean and Associates. Proje=t: The South Slope project ~ill comprise 702 to 745 dwelling units and a 25 acre commercial, site. The-=ommer¢ial site is proposed for part of the.area adjacent to Bayshore Boulevard, aU the~astern end of the project site (Figure 2-04 F). The project will result ih permanent disturbance of 135 acres of land and temporary disturbance of 68 acres which will be reclaimed (see Figure 2-04 G). The reclamation of temporarily disturbed areas will initially be the responsibility of th~ developer but will eventually be turned over to the Plan Operator along with the undisturbed area and become part of the Conserved Habitat° See Figures 2-04 H to J. Status: This is a planned parcel. Amendments to the HCP resulted in the addition of 25 acres of temporary disturbance and a reduction of 5 acres of ~ permanent disturbance from that anticipated in the Concept Plan. -- Biological Issues: The site 6f the South Slope Project is grasslan~ dominated by eurepean annual grasses and contains host plants of the both the Mission Blue and the Callippe Silverspot butterflies. While the main populations of the butterflies are on the upper slopesv they were found to utilize the lower area to some degree. Of the two insects, more Mission. Blue were found in the' South Slope area during the 1981 field season (See Figures 2-04 D-E). This area is also habitat for three range limit or endemic plants, and the rare plant, Orthocaruus floribundus is expected in the ravines;' however, it was .~ .- not located during the 1981 field study, or subsequent field surveys done.in ".' ~?.1982~ 1983 and 1984. Finally, the grassland also supports general grassland ~-~ species, and during the course of the biological study Mule deer, jack rabbits and assorted grassland birds were observed. ' 'Impact: Development of the South Slope as specified in the Precise Plan will destroy 3.22% of the population of the Mission Blue butterfly and 0.46% of the population of the Callippe Silverspot butterfly, It will also remove habitat now used by the butterflies of concern and other grassland species, and will destroy any range limit or endemic plaints on the site. fKIPObjectives -- Specific Conservation Needs: The HCP approach to the South Slope is to prevent sudden loss of habitat all at once by phasing the project so that reclamation of cut and fill slopes with host plant species can begin in the first phase before the final phase of development takes place. APPENDIX A A~'i O~erating' Pro. ram Obligations: .~he landowner/developer has the following obligations: 1. ~ construction or conversion to urban uses shall be permitted in the area designated 2-04-02 on Figure 2-04 C. The boundary of area 2-04-02 may be adjusted by the Landowner by not more than fifty (50) feet from the line shown on Figure 2-04 C, provided, however, that the total area increased as a result of such adjustment does not exceed ten (10) acres. Outside area 02 construction and conversion to urban uses may occur subject only to the ~onditions set forth in Paragraph..2 below. 2. Prior to any construction wit>in Administrative Parcel 2-04, the'Landowner shallprovide for the following: · a. Dedication of Conserved R~bitat. ~he L~n.'downer shall agree to dedicate to the County all lands within Administrative Parcel 2-04 within area 2-04-02 shown in Figure 2-04.C and as adjusted by the Landowner pursuant to Paragraph 1.. Such dedication shall be offered by the Landowner at the time of receipt.of the first'grading permit with respect to the parcel of the project to which it pertains, (see Figure 2-04 J. ~CP Funding ProGram. During the pre-development phase of the HCP, the landowner/developer will contribute to a pre-development fund. During the project development phase, the developer will enter into a contract with the Plan Operator to pay the reasonable cost of ~u~ervisin~ the HCP'restrictions on grading a~d supervising the reclamation of habitat. Finally, after development the Landowner shall obligate future residents, through C C ~ R's and covenants running with the land to to an annual assessment of $20.00 per dwelling unit or the equivalent adjusted for inflation to 1983 dollars. ?he funds will be paid to the San Bruno Mountain' Conserva%ion Fund. See Chapter V-B for details of funding and timing. Construction Provisions. In accordance with Paragraph 1 above, the Landowner shall not disturb any land in area 2-04-02 except as provided in 2d below. In addition, the Landowner shall not grade more than one phase per year. Grading phases are shown in Figure 2-04 I. Reclamation Provisions. With respect to any areas which are to be graded or disturbed and thereafter dedicated as Conserved ~abitat, the Landowner shall prepare a Reclamation Plan for approval by the City (or County, as the case may be) in accordance with its normal standards and ~rocedures for grading permits. These provide for grading, erosion and run-off controls, and revegetation with native grassland species approved by the Plan Operator. In addition, the Landowner shall clearly define on the ground (by snow or two strand wire fencing or other methods) the limits of disturbance anticipated and shall limit the construction disturbance to said limits as · provided in fencing and signing provisions of the MOU and Chapter 5. The fencing shall be constructed at the boundary between the temporarily disturbed areas and the permanently disturbed areas as A-2 p~VISED CHAPTER VIi .~?.E HCP FOR PARCEL '2-04, ! SOUl, LoPE PROJECT shown in Figure 2-04 G. A~ the time of approval of the reclamation plan(s), those plans shall substitute for the more generalized maps referenced in this section. e. Pesticide Control. The Landowner shall establish covenants and restrictions encumbering Development Areas in favor of the County and/or City prohibiting the use of aerial or large-scale spraying of pesticides without the approval of the Plan Operator.' f. 'Buffer Areas, The Landowner shall covenant in favor of the City of South San Francisco and the County to establish and maintain a buffer - area of up to thirty {30) feet in width to protect urban, uses within the Development Areas fr-- fire. Native plants, which will not _Dr. esent an invasion threat to gra.sslands within the Conserved Habitat, are preferred. %.,~se buffer a32eas will be maintained by the Homeowners Association. g, Insuecticn. The Landowner shall.,' in carrying out Reclamation Plans for Administrative Parcel 2-04, contract for an inspector actina for 'the County as Plan O_Derator to monitor gradin¢? and revegetation activities through completion of the reclamation activities and acceptance of the offer of dedication. 3. Fund an off-site ennancement program (described below) which is prescribed-~o mitigate impacts caused by additional habitat disturbance from geotechnical prooiems within the South Slope project. The enhancement program will take place on a thirty acre .area located iD the ess~:ern sadOle. It is ~,.ithin the San Bruno M6untain State and County Park and is part o( Administrative Parcel 1-09~ See Figures 2-04-K and L. 'The off-site enhancement area consists of grassland habitat, rocky outcroppings, ~cau~ered areas of brush (mainly gorse), and eucalyptus trees. The particular sihe was chosen for enhancement because it contains good habitat for the ..'4ission Blue and Callippe Silverspot butterflies. However, the area has recently become subject to gorse and eucalyptus invasion. There are many scattered bunches of gorse (approximately 10 acres) in and · among the larval host plants of both the Mission Blue and CaliipDe. Without control the gorse will eventually out compete the butterfly host plants. The eucalyptus, which are mainly along Guadalu:e Canyon Parkway act as a barrier to butterfly dispersal. Thinning of these trees can help eliminate the barrier affect. Work Program Specifications: Exotic Suecies Removal. Generally this task involves hand removal o~ invading patches of gorse, follow up herbicide application of stumps, and thinning of eucalyptus trees as appropriate. The following specific measures must be followed by the shrub removal contractor. a) Prior to the start of the exotic species removal process the boundaries of the site will. be staked by the Habitat Manager. b) The' field supervisor will consult with the Habitat Manager as to the priority of gorse patches to be removed. A-3 REVISED CHAPTER VII OF THE HCP FOR PARCEL 2-04, S©UTH SLOPE PROJECT c) Access to each patch will be clearl'_; understood and marke~ in the field. d} No heavy equipment will be allowed on the site without prior permission by the Habitat Manager. e) All cut brush will be piled up for later burning by the California Department of Forestry. The Habitat Manager should be consulted as to the best area for placing the burn piles. f) All personnel will be made aware of sensitive habitat areas near the - .gorse patches. g) All removal work is to be done using hand equipment (i.e. chain saws, .axes, loppers, etc)' unless ot~.~wise ihstr .u?t. ed by the habitat manager. h) The Habitat Manager will make periodic visits to the site to assure the work is being done properly and to answer any questions which may arise. i) .Remove eucalyptus trees within the designated area. j) At least one spray application of an approved herbicide will be applied to the gorse stumps. Follow up control will be done by the Habitat Manager. Container Plan=in~ and Direct Seedin~ of Host Plants. This should be done upon successful con=roi-of exotic species. To be done under the supervision of Clyde Robin S~ed Company with plants and seeds supplied by them. Follow up Wor~ as Needed. Continued control of resprouting or reseeding gorse and eucalyptus. Monitoring the growth and butterfly utilization of the container plants and seedlings. This task will be performed by the Habitat Manager as part of the overall HCP work program. The enhancement planting will take place when the Plan Operator has been-assured that the gorse will not require further herbicide treatment (within five years after the removal has taken place). The plants and seed needed for the enhancement can be obtained during these ~ive years. The Supervision is required to assure no habitat damage takes place during the exotic species removal process. Every hour spent on supervision will be billed to the developer. The developer must also provide for the on-site reclamation of anY'slide repair disturbance as specified in the HCP for temp6rarily disturbed areas. Full costs to be borne by developer as specified in the HCP; a reclamation plan for these areas must be approved by Plan Operator. A-4 The Plan Operator has the followin~ obligations: 1. Prepare and execute an annual operating program for the Conserved Habitat within Administrative Parcel 2-04; 2. Monitor the effect of all activities within Development Areas on adjacent Conserve~Habitatand within the off-site enhancement area and provide advice and direction to the Landowner to assist his compliance with the 6bligatipn~ described above with respect'to Administrative Parcel 2-04; 3. Designate.vegetation materials for use in Reclamation plans and review such Reclamation Plan~ submitted by the Landowner with respect to Administrative Parcel ~-04 in a timely fashion to avoid delays in the implementation of such Plans; 4. .Accept dedications of Conserved ~abita~ witlTin Administrative Parcel 2-04.

It has a varied flora, ranging from grassland on the south slope and ridgeline to brushand woodland on the north side. Ownership: The entire parcel is owned by the.County of San Marco. Project: The County has proposed a system of hiking trails in this portion of the Park which will be created out of existin9 fire roads modified fo= easier use. Other than thes~ trails, whi[k° include vista points, no park facilities are.proposed for this section of the park (Figurp'2-05 F). Grading or minor disturbance activities required for the South Slope development will take place on 1.5 acres of County Park land. The ·temporarily graded areas will be reclaimed with native San Bruno Mountain plant species.. Status: This is a planned parcel. Biological Issues: The Southeast Ridge portion of the County Park contains much of the prime Mission Blue and Callippe habitat (See Figures 2-05 D-E). The south-facing slopes in particular have abundant lupine, violet, and butterfly nectar plants. The area also houses several range limit and endemic plant species, and the rare plant Orthocarpus floribundus is expected but was not found during the R'iological Study, 1980-81. In addition to the plants, this area cf the park is habitat for the San Bruno Elfin Butterfly and the Bay Checkerspot butterfly, which was thought to be extinct on SBI4~ and several other species Of plants and animals which frequen~ grassland and brush. On the north side, Buckeye Canyon supports a woodland habitat which is unique to San Bruno Mountain. Impact: Since the proposed trails are to be created out of existing fire roads, there will not be a loss of habitat concurrent with trail construction. Impacts may be caused if realignment upgrading is required. Also, if this portion of the park is heavily patronized and people do not remain on trails, further impacts may be caused. Grading or minor disturbance activities for the South Slope project will disturb 1.5 acres of Mission Blue and Callippe Silverspot butterfly habitat located within the County Park parcel, H(iPObje~tives --Specific Conservation Needs: ~e County Park is intended to be used as a regional recreation area for the surrounding urban centers, inviting people to learn about the unique ecology of San Bruno Mountain. It will also serve as a way to preserve that ecology. '~erefore, the HCP approach to the County Park is to conserve existing habitat by minimizing the effects of human encroachment. This will be achieved through 'minimal construction and limited access to particularly sensitive areas. In order to conserve the habitat which exists ~n the park, careful consideration will have to be given to trail construction and use. In this section of the park, the adjustments necessary to make the trails useful to park patrons, i.e. turning steep trails into switchback trails, must be carefully considered before initiated; trails should not destroy large areas A-18 .~ R~VISED CFL%PTER VIi . ?q..E HCP FOR PARCEL ~!-05, COUN P~RK of habitat, or disrupt areas heavliy utilized by the butterflies of concern. In addition,, the trails should avoid San Bruno Elfin and Bay Checkerspot habitat. Once the trails are in place park users should be made to keep within the trail boundaries. This could ke achieved by posting signs which describe the unique ecology of the locale and require users to remain on the trails in order to help preserve that ecology. Sensitive areas should be monitored in order to assess imgact: areas aDD~aring to b~ hea~{ly ~mpa~e8 will require stronger measures such as fencing or patrolling ].n order to .prevent users from moving out into the unmarked grassland or brush areas.. The grading required for the'South Slope project will be regulated by the strict construction provisions ~efined in the operating program for that project. These provisions .include constructing a temporary habitat fence at the boundary between temporarily disturbed areas and undisturbed areas, posting signs mlong the fenc~'which star, the penalty for grading beyond the fenced areas, and the reclamation of-all temporarily disturbed areas with native plants. _Operating Pro, ram Obligations: The County of San Mateo has the following obligations: 1.
