    City of Morro Bay Community Development Department 955 Shasta Avenue Morro Bay, Ca 93442 805-772-6261 NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION The City of Morro Bay Community Development Department has completed the Draft Initial Study/Mitigated Negative Declaration (IS/MND) for the proposed 3300 Panorama Drive, Demolition of Tanks and Associated Structures Project. The Draft IS/MND found the following environmental factors to be less than significant with mitigation incorporated: Aesthetic Resources, Air Quality, Biological Resources, Cultural Resources, Geology and Soils, Hazards/Hazardous Materials, Hydrology, Noise, Transportation and Traffic, and Tribal Cultural Resources. APPLICANT: Rhine LP and Morro94 GENERAL PLAN DESIGNATION: Medium-Density Residential/Environmentally Sensitive Habitat PROJECT LOCATION: The 10-acre project site is located at 3300 Panorama Drive, at the northeast corner of the City of Morro Bay, within the city limits. The project site was previously used by the Department of the Navy for jet fuel storage and distribution, and is within the R-1/PD/ESH (Single- Family Residential/Planned Development/Environmentally Sensitive Habitat [ESH]) zoning district and designated by the General Plan and Coastal Land Use Plan (CLUP) as Medium-Density Residential. PROJECT DESCRIPTION: Rhine LP and Morro94, LLC (the owners/applicant) propose to demolish and remove two large JP-5 fuel storage tanks (131,600 barrels, approximately 5,527,000 gallons each) once used by the United States Navy to store jet fuel, one approximately 100,000-gallon water tank, and associated pumps and piping from the decommissioned fuel storage site formally known as the DFSP, located at 3300 Panorama Drive in Morro Bay, California.

  • San Luis Obispo County
    Steelhead/rainbow trout resources of San Luis Obispo County San Carpoforo (San Carpojo) San Carpoforo Creek (San Carpojo Creek) consists of more than ten stream miles. It flows southwest, entering the Pacific Ocean at Ragged Point. Staff from DFG surveyed San Carpoforo Creek in 1961 and observed O. mykiss, with highest population density in the lower one mile of the creek. The survey report relays information from local residents and DFG staff including an estimate of “…155 adult steelhead in three holes between the mouth of the stream and the mine” in the late 1950s (DFG 1961a). The creek was deemed, “…a good steelhead nursery and spawning area” (DFG 1961a). In a 1966 letter DFG states, “San Carpojo and Arroyo de la Cruz Creeks are the best steelhead waters in San Luis Obispo County” (DFG 1966a). A 1973 draft report on the effects of potential water developments included estimates of steelhead run size in several San Luis Obispo County creeks. The estimated adult run in San Carpoforo Creek was 500 individuals (Macias 1973). Staff from DFG surveyed San Carpoforo Creek in 1995 and observed “numerous” young of the year, age 1+ and age 2+ steelhead (DFG 1995a). The survey report indicates that the surveyed stream reach usually becomes intermittent by the end of summer. In 1999, USFS staff surveyed San Carpoforo Creek and observed “lots of trout” including fry and adults (USFS 1999a). Staff from NMFS performed systematic surveys of south coast streams in 2002-2003 to determine steelhead presence/absence. The survey report form for San Carpoforo Creek indicates multiple O.

  • The Impact of Coastal Dredging on Avian and Intertidal Macroinvertebrate Biodiversity of Morro Bay, California
    ABSTRACT THE IMPACT OF COASTAL DREDGING ON AVIAN AND INTERTIDAL MACROINVERTEBRATE BIODIVERSITY OF MORRO BAY, CALIFORNIA Sandy beaches support dynamic and diverse, but physically narrow intertidal ecosystems that are vulnerable to the effects of anthropogenic disturbance, such as coastal dredging and beach nourishment. Our study site in Morro Bay, California has been a site of coastal dredging by the U.S. Army Corp of Engineers (USACE) since the 1960’s. In February of 2017, 240,000 cubic yards of sediment were dredged from the harbor and deposited onto the beach as beach nourishment. We assessed the impacts of this beach nourishment over two years on three aspects of beach ecosystems: 1) beach width, 2) avian biodiversity, and 3) intertidal macroinvertebrate biodiversity. We designated seven sampling sites and at each collected monthly measurements of beach width, monthly avian point counts, and quarterly macroinvertebrate samples. We found spatiotemporal variation present across months and sites, and beach width at the deposition site was significantly higher than the six control sites pooled together. Avian and macroinvertebrate biodiversity was not significantly different at the deposition site compared to the pooled control sites. Our results suggest that the dredge deposition had low or very short-term impacts to both avian and intertidal macroinvertebrate biodiversity at the deposition site over our two years of sampling. Positive impacts include a wider beach at the deposition site. Shelby Paige Moshier May 2020 THE IMPACT OF COASTAL

  • Evidence of Tectonic Uplift Along the Oceanic Fault Near San Simeon, San
    i Evidence of Tectonic Uplift along the Oceanic Fault near San Simeon, San Luis Obispo County, California A Senior Project presented to the Faculty of the Earth and Soil Science Department California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Earth Science; Bachelor of Science by George Gecy March, 2011 © 2011 George Gecy ii Approval Page TITLE: Evidence of Tectonic Uplift along the Oceanic Fault in San Simeon AUTHOR: George Gecy DATE SUBMITTED: March 2011 Dr. Antonio F. Garcia_________ ___________________________ Senior Project Advisor Signature Dr. Lynn E. Moody ___________ ___________________________ Department Chair Signature iii Acknowledgements I would like to thank Dr. Garcia, my friends and my family for all the little help along the way. iv Abstract Post-Seismic satellite imagery after the 2003 earthquake near San Simeon confirmed 10s of millimeters of north-east side uplift along the Oceanic Fault. In order to determine whether or not there has been a history of tectonic uplift northeast of the Oceanic Fault zone, longitudinal profiles of Morro Creek and San Simeon were made using a digital planimeter and 1:24,000 scale maps. Utilizing the stream profiles, convexities could be observed in the streams coinciding where the streams crossed the Oceanic Fault; of the stream profiles, the convexity along San Simeon Creek could be confirmed to be caused by north-east side uplift along the Oceanic Fault. v Table of Contents Approval Page ................................................................................................................................

    SoCal Biodiversity - Animals Arboreal Salamander Amphibian SoCal Biodiversity - Animals Arboreal Salamander Amphibian Arroyo Toad Arboreal Salamander Arboreal Salamander (Aneides lugubris) Management Status Heritage Status Rank: G5N5S4 Federal: None State: None Other: Species identified as a local viability concern (Stephenson and Calcarone 1999) General Distribution Arboreal salamander occurs in yellow pine and black oak forests in the Sierra Nevada, and in coastal live oak woodlands from northern California to Baja California. The species also occurs in the foothills of the Sierra Nevada from El Dorado County to Madera County and on South Farallon, Santa Catalina, Los Coronados, and Ano Nuevo islands off the coast of California (Petranka 1998, Stebbins 1951, Stebbins 1985). Arboreal salamander occurs from sea level to an elevation of about 5,000 feet (1,520 meters) (Stebbins 1985). Distribution in the Planning Area Arboreal salamander reportedly occurs in the foothills and lower elevations of every mountain range on National Forest System lands, although it is seldom seen (Stephenson and Calcarone 1999). There are records of occurrence for this species on the Los Padres National Forest near upper San Juan Creek and on the Cleveland National Forest near Soldier Creek (USDA Forest Service file information), San Gabriel foothills east to Day Canyon, and in the San Jacinto Mountains (Goodward pers. comm.). Systematics There are four species in the genus Aneides in the western United States, three of which occur in California (Stebbins 1985). Of these three, only arboreal salamander ranges into southern California. Most of the Aneides salamanders climb (Stebbins 1985). Arboreal salamander consists of two chromosomally differentiated groups that intergrade in south and east-central Mendocino County, about 56 miles (90 kilometers) north of the San Francisco Bay region (Sessions and Kezer 1987).
