biological assessment was prepared by Jacobszoon and Associates Inc. for the City of Ukiah for the purpose a lot line adjustment to reconfigure parcels for future single-family residential development on approximately 55 acres. The project site is located just west of Ukiah, CA within Sections 19 and 30, Township 15N, Range 12W, Mount Diablo Base and Meridian, in the Ukiah USGS 7.5-minute quadrangle, APNs: 001-040-83, 157-070-01, 157-070-02, and 003- 190-01 (Appendix D: Map 1, Study Area- Topographic Map). A site visit was conducted on February 5, 2021. A botanical survey was conducted on March 30, 2021. Additional botanical survey results will be amended in once completed. The purpose of this study was to identify and map areas within the parcel that are potential sensitive natural communities and to locate special-status plants and special-status animal habitats to determine if they would be directly or potentially impacted by the proposed project. The Study Area referred to within this report comprises approximately 55 acres and includes existing dirt and gravel roads, fire breaks, water tank pad sites, and areas cleared for potential house sites (Appendix D: Map 2, Study Area-Aerial Map). This report includes the following: • Regulations and Project Description (Section 2) • Field Survey Methodology (Section 3) • Study Area Setting (Section 4) • Field Survey Results (Section 5) • Assessment Summary and Recommendations (Section 6) • Tables of Special-Status Plants and Wildlife within CNDDB nine quads (Appendix A) • List of Species Observed (Appendix B) • Representative Photographs of Study Area (Appendix C) • Supporting Maps (Appendix D) • Supporting Documents (Appendix E) Section 2.0: Regulations and Descriptions 2.1 Regulatory Setting In addition to the requirements of Mendocino County’s permitting process, the project shall comply with Federal, State, and local regulations designed to protect sensitive natural resources. The following natural resources are protected under one or more of several Federal and/or State regulations and should be considered when designing and/or implementing the proposed project within the Study Area: Essential Fish Habitat: protected through changes to the Magnuson-Stevens Fishery Conservation and Management Act to maintain sustainable fisheries in the United States, administered by National Marine Fisheries Service (NMFS):

  • Conceptual Design Documentation
    Appendix A: Conceptual Design Documentation APPENDIX A Conceptual Design Documentation June 2019 A-1 APPENDIX A: CONCEPTUAL DESIGN DOCUMENTATION The environmental analyses in the NEPA and CEQA documents for the proposed improvements at Oceano County Airport (the Airport) are based on conceptual designs prepared to provide a realistic basis for assessing their environmental consequences. 1. Widen runway from 50 to 60 feet 2. Widen Taxiways A, A-1, A-2, A-3, and A-4 from 20 to 25 feet 3. Relocate segmented circle and wind cone 4. Installation of taxiway edge lighting 5. Installation of hold position signage 6. Installation of a new electrical vault and connections 7. Installation of a pollution control facility (wash rack) CIVIL ENGINEERING CALCULATIONS The purpose of this conceptual design effort is to identify the amount of impervious surface, grading (cut and fill) and drainage implications of the projects identified above. The conceptual design calculations detailed in the following figures indicate that Projects 1 and 2, widening the runways and taxiways would increase the total amount of impervious surface on the Airport by 32,016 square feet, or 0.73 acres; a 6.6 percent increase in the Airport’s impervious surface area. Drainage patterns would remain the same as both the runway and taxiways would continue to sheet flow from their centerlines to the edge of pavement and then into open, grassed areas. The existing drainage system is able to accommodate the modest increase in stormwater runoff that would occur, particularly as soil conditions on the Airport are conducive to infiltration. Figure A-1 shows the locations of the seven projects incorporated in the Proposed Action.

We have never had so many problems in fitting the range of plants we have “on our books” into the available space! We always try and keep our lists “democratic” and balanced although at times our prejudices show and one or two groups rise to the top. This year we are offering an unprecedented range of calochortus in a multiplicity of sizes, colours and flower shapes from the charming fairy lanterns of C. albidus through to the spectacular, later-flowering mariposas with upward-facing bowl-shaped flowers in a rich tapestry of shades from canary-yellow through to lilac, lavender and purple. Counterpoised to these flashy dandies we are offering an assortment of choice muscari whose quiet charm, softer colours and Tulipa vvedenskyi Tecophilaea cyanocrocus Violacea persistent flowering make them no less effective in the winter and spring garden. Standouts among this group are the deliciously scented duo, M. muscarimi and M. macrocarpum and the striking and little known tassel-hyacith, M. weissii. While it has its devotees, many gardeners are unaware of the qualities of the large and diverse tribe of “onions”, known as alliums.

Erythronium californicum is another excellent garden plant which is most often seen under the cultivar name of Erythronium ‘White Beauty’ this is readily available. I include ‘White Beauty’ here, rather than under hybrids, as there are no morphological indications that any other species is involved. What makes this form such a good garden plant is its ability to tolerate a wide range of garden types and increase well by division: a healthy well- grown bulb can make two new flowering sized bulbs plus have several smaller offsets every year – it also regularly sets seed. Erythronium ‘White Beauty’ ERYTHRONIUMS IN CULTIVATION © Ian Young Erythronium californicum All forms are free flowering, setting seed most years provided the weather conditions at flowering time are not too cold and wet. Erythronium ‘White Beauty’ has fewer seeds in the capsule compared to other forms; about one third of the number. Erythronium californicum seeds ERYTHRONIUMS IN CULTIVATION © Ian Young Bulb On the left is a group of Erythronium californicum bulbs showing the typical shape – the longer thin ones are younger bulbs still taking themselves down into the ground seeking the best conditions. Most forms will increase by offsets, soon forming clumps – forms such as ‘White Beauty’ form clumps quickly, see below, and are best lifted and divided every three to five years to maintain good flowering.

  • Fire-Resistant Plants for Oregon Home Landscapes
    FFire-ire-RResistantesistant PlantsPlants forfor OregonOregon HomeHome LandscapesLandscapes Suggesting specific types of vegetation that may reduce your risk from wildfire. Stephen Fitzgerald Area Extension Forester and Associate Professor Amy Jo Waldo Area Extension Horticulture Agent and Assistant Professor OSU Extension Service 1421 S. Hwy 97, Redmond, OR 97756 Introduction Oregon has many wildfire prone areas. In these places, fires are a natural part of the changing landscape. As homes are built in these areas, special precautions must be taken by the homeowner to pro- tect their property. Installation of fire- resistive roofing is critical to preventing firebrands from igniting the home from a roof fire. Well maintained fire-resistant vegetation and irrigated landscape is also critical within close proximity of a home. These actions DO NOT insure that your home will survive a wildfire, but they provide for a good chance of structural survival. Implementation of FireFree [www.firefree.org] and FireWise [www.firewise.org] activities can also significantly improve chances of a home surviving a wildfire. Fire-resistant vegetation. When landscaping around a home, most homeowners are interested in creating a landscape that is aesthetically pleasing, compliments their home, and has varia- tions in color, texture, flowers, and foliage. If your home is located in or adjacent to forests or rangeland, you should also consider the flammability of plants within your home landscape. Flammable plant material in your land- scape can increase the fire-risk around your home. The 1991 Oakland Hills Fire in California is a prime example of how flam- mable plant material (Eucalyptus trees) can act as fuel and contribute to the inten- sity of a wildfire.

Critique and assessment of the existing body of published literature against our criteria focussing on studies that can support best management resulted in 19 experimental papers. Indirect measures of competition examining foraging patterns and behavior yielded equivocal results. Direct measures of reproduction and growth were investigated in only seven studies, with six indicating negative impacts to wild bees from the presence of managed honey bees.
