Initial Study/Mitigated Negative Declaration May 2015 ii 1.0 INTRODUCTION 1.0 INTRODUCTION 1.1 INTRODUCTION AND REGULATORY GUIDANCE This document is an Initial Study (IS), prepared consistent with California Environmental Quality Act (CEQA) Guidelines Section 15063, with supporting environmental studies providing justification for a Mitigated Negative Declaration (MND) pursuant to CEQA Guidelines 15070, for the routine maintenance of stream channels and drainage facilities in Elk Grove. The Initial Study/Mitigated Negative Declaration (IS/MND) is a public document to be used by the City of Elk Grove to determine whether the Project may have a significant effect on the environment pursuant to CEQA. If the lead agency finds substantial evidence that any aspect of the Project, either individually or cumulatively, may have a significant effect on the environment that cannot be mitigated, regardless of whether the overall effect of the Project is adverse or beneficial, the lead agency is required to prepare an environmental impact report (EIR), use a previously prepared EIR and supplement that EIR, or prepare a subsequent EIR to analyze the project at hand (State CEQA Guidelines Section 15063). If the agency finds no substantial evidence that the Project or any of its aspects may cause a significant impact on the environment with mitigation, a negative declaration is to be prepared with a written statement describing the reasons why the proposed Project would not have a significant effect on the environment and therefore why it does not require the preparation of an EIR (State CEQA Guidelines Section 15371). According to State CEQA Guidelines Section 15070, a negative declaration is to be prepared for a project subject to CEQA when either: a) The initial study shows there is no substantial evidence, in light of the whole record before the agency, that the proposed project may have a significant effect on the environment, or b) The initial study identifies potentially significant effects, but: (1) Revisions in the project plans or proposals made by or agreed to by the applicant before the proposed negative declaration is released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effects would occur, and (2) There is no substantial evidence, in light of the whole record before the agency, that the proposed project as revised may have a significant effect on the environment. This IS/MND has been prepared in accordance with CEQA, Public Resources Code Section 21000 et seq., and the State CEQA Guidelines, Section 15000 et seq., Title 14, California Code of Regulations. 1.2 LEAD AGENCY The lead agency is the public agency with primary responsibility over a proposed project. Where two or more public agencies will be involved with a project, CEQA Guidelines Section 15051 provides criteria for identifying the lead agency. In accordance with CEQA Guidelines Section 15051(b)(1), “the lead agency will normally be the agency with general governmental powers.” The City of Elk Grove Public Works Department is responsible for providing routine maintenance of the City’s drainage facilities. The Project requires approvals from the Elk Grove City Council. Therefore, based on the criteria described above, the City is the lead agency for the proposed Project. City of Elk Grove Routine Creek Maintenance May 2015 Initial Study/Mitigated Negative Declaration 1.0-1 1.0 INTRODUCTION 1.3 PURPOSE AND DOCUMENT ORGANIZATION The purpose of this IS/MND is to evaluate the potential environmental impacts of the proposed routine maintenance of stream channels and drainage facilities in Elk Grove. Mitigation measures have been identified to reduce or eliminate any identified significant and/or potentially significant impacts. This document is divided into the following sections: 1.0 INTRODUCTION Provides an introduction

  • Vernal Pool Fairy Shrimp (Branchinecta Lynchi)
    fairy shrimp populations are regularly monitored by Bureau of Land Management staff. In the San Joaquin Vernal Pool Region, vernal pool habitats occupied by the longhorn fairy shrimp are protected at the Kesterson National Wildlife Refuge. 4. VERNAL POOL FAIRY SHRIMP (BRANCHINECTA LYNCHI) a. Description and Taxonomy Taxonomy.—The vernal pool fairy shrimp (Branchinecta lynchi) was first described by Eng, Belk and Eriksen (Eng et al. 1990). The species was named in honor of James B. Lynch, a systematist of North American fairy shrimp. The type specimen was collected in 1982 at Souza Ranch, Contra Costa County, California. Although not yet described, the vernal pool fairy shrimp had been collected as early as 1941, when it was identified as the Colorado fairy shrimp by Linder (1941). Description and Identification.—Although most species of fairy shrimp look generally similar (see Box 1- Appearance and Identification of Vernal Pool Crustaceans), vernal pool fairy shrimp are characterized by the presence and size of several mounds (see identification section below) on the male's second antennae, and by the female's short, pyriform brood pouch. Vernal pool fairy shrimp vary in size, ranging from 11 to 25 millimeters (0.4 to 1.0 inch) in length (Eng et al. 1990). Vernal pool fairy shrimp closely resemble Colorado fairy shrimp (Branchinecta coloradensis) (Eng et al. 1990). However, there are differences in the shape of a small mound-like feature located at the base of the male's antennae, called the pulvillus. The Colorado fairy shrimp has a round pulvillus, while the vernal pool fairy shrimp's pulvillus is elongate.

  • Conservancy Fairy Shrimp (Branchinecta Conservatio)
    2. CONSERVANCY FAIRY SHRIMP (BRANCHINECTA CONSERVATIO) a. Description and Taxonomy Taxonomy.—The Conservancy fairy shrimp (Branchinecta conservatio) was described by Eng, Belk, and Eriksen (Eng et al. 1990). The type specimens were collected in 1982 at Olcott Lake, Solano County, California. The species name was chosen to honor The Nature Conservancy, an organization responsible for protecting and managing a number of vernal pool ecosystems in California, including several that support populations of this species. Description and Identification.—Conservancy fairy shrimp look similar to other fairy shrimp species (Box 1- Appearance and Identification of Vernal Pool Crustaceans). Conservancy fairy shrimp are characterized by the distal segment of the male’s second antennae, which is about 30 percent shorter than the basal segment, and its tip is bent medially about 90 degrees (Eng et al. 1990). The female brood pouch is fusiform (tapered at each end), typically extends to abdominal segment eight, and has a terminal opening (Eng et al. 1990). Males may be from 14 to 27 millimeters (0.6 to 1.1 inch) in length, and females have been measured between 14.5 and 23 millimeters (0.6 and 0.9 inch) long. Conservancy fairy shrimp can be distinguished from the similar looking midvalley fairy shrimp (Branchinecta mesovallensis) by the shape of two humps on the distal segment of the male's second antennae (Belk and Fugate 2000). The midvalley fairy shrimp's antennae is bent such that the larger of the two humps is anterior (towards the head), whereas this same hump in the Conservancy fairy shrimp is posterior (towards the tail).

The information contained in this analysis is primarily based upon the Biological Assessment, Gentry-Suisun Project, City of Suisun City, Solano County, California prepared by The Huffman-Broadway Group (2006) and the Wetland Delineation and Special- Status Species Survey Report prepared by Vollmar Consulting (2003). Additional details on plant and wildlife species presence are based upon field surveys performed by Foothill Associates’ biologists. This report describes the habitat types, jurisdictional waters, and presence/absence of special-status plants and animals at the Proposed Project area and provides a review of existing literature, maps, and aerial photography pertaining to the biological resources of the area. It also evaluates potential impacts of the proposed Project in relation to CEQA and other environmental laws, and provides mitigation recommendations. Foothill Associates has prepared this Section of the EIR for the proposed Suisun Gentry Project (Project) in central Solano County, California.

  • VERNAL POOL FAIRY SHRIMP Branchinecta Lynchi USFWS: Threatened CDFG: None
    LSA ASSOCIATES, INC. PUBLIC DRAFT SOLANO HCP JULY 2012 SOLANO COUNTY WATER AGENCY NATURAL COMMUNITY AND SPECIES ACCOUNTS VERNAL POOL FAIRY SHRIMP Branchinecta lynchi USFWS: Threatened CDFG: none Species Account Status and Description. The vernal pool fairy shrimp was listed as a federally Threatened Species on September 19, 1994 (59 FR 48153). Critical habitat was designated for the vernal pool fairy shrimp in 2005 (USFWS 2005). The vernal pool fairy shrimp is a small crustacean in the Branchinectidae family. The species has elongate bodies, large-stalked compound eyes, no carapaces (hard protective outer covers), and 11 pairs of swimming legs (Eng et al. 1990). Adult shrimp range between 0.4-1.0 inches in length (Eng et al. 1990). Vernal pool fairy shrimp are similar in appearance to Colorado fairy shrimp (Branchinecta coloradensis). However, the basal segment outgrowth below and posterior to the pulvillus of the antennae of male vernal pool fairy shrimp is ridge-like, while the basal segment outgrowth of the Colorado fairy shrimp is cylindrical and usually larger (Eng et al. 1990). The vernal pool fairy shrimp has a shorter, pyriform brood pouch, whereas the Colorado fairy shrimp has a longer, fusiform brood pouch (Eng et al. 1990). Range, Populations and Activity. The historic range of the vernal pool fairy shrimp likely coincided with the historical distribution of vernal pools in the Central Valley of California, southern California and southern Oregon (USFWS 2005). The vernal pool fairy shrimp is currently found in 28 counties across the Central Valley and coast ranges of California, and in Jackson County of southern Oregon.
