prepared to conform to the requirements of the California Environmental Quality Act (CEQA), the CEQA Guidelines (California Code of Regulations §15000 et.seq.) and the regulations and policies of the City of Morgan Hill. This Initial Study evaluates the environmental impacts that might reasonably be anticipated to result from implementation of the proposed Connemara Residential Project. The 10.36-acre project site (APNs 779-03-137, -138, and -139) is located in the City of Morgan Hill on the southeast side of Watsonville Road, south of Olive Avenue and north of Santa Teresa Boulevard. The project applicant has requested a zoning amendment for APN 779-03-139 to R1-7,000 and approval of a Planned Development (PD) overlay on all three project parcels to allow a subdivision with 37 single- family detached houses. An on-site stormwater retention pond, private open space, and internal roadways, are also part of the project. The City of Morgan Hill is the Lead Agency under CEQA and has prepared this Initial Study to address the impacts from implementation of the project. City of Morgan Hill Initial Study Connemara Residential Project 1 January 2013 SECTION 2 PROJECT INFORMATION 2.1 PROJECT TITLE Connemara Residential Project 2.2 PROJECT LOCATION The project site is a 10.36-acre property developed with five single-family detached houses, a former chicken coop, a vehicle garage/storage shed, auxiliary structures, and associated infrastructure. The site is located on the southeast side of Watsonville Road, south of Olive Avenue and north of Santa Teresa Boulevard in the City of Morgan Hill, (refer to Figures 1 and 2). The project site is bound by agricultural land and rural single-family residential development to the north, single-family residences to the east, single-family attached and multi-family residences to the south, and Watsonville Road and single-family residences to the west, (refer to Figure 3). 2.3 PROJECT PROPONENT Dick Oliver Dividend Homes 385 Woodview Avenue, Suite 100 Morgan Hill, CA 95037 2.4 LEAD AGENCY CONTACT City of Morgan Hill Rebecca Tolentino, Senior Planner Community Development Agency 17575 Peak Avenue Morgan Hill, CA 95037 (408) 778-6480 2.5 ASSESSOR’S PARCEL NUMBERS APNs 779-03-137, -138, and -139 2.6 GENERAL PLAN DESIGNATION AND ZONING DISTRICT Existing General Plan Designation: Single-Family Medium (3-5 dwelling units per acre [du/ac]) Existing Zoning District: R1-7,000 (APN 779-03-137 and 138) R1-9,000 (APN 779-03-139). Proposed Zoning: R1-7000, Planned Development (PD) for entire site. City of Morgan Hill Initial Study Connemara Residential Project 2 January 2013 SECTION 3 PROJECT DESCRIPTION 3.1 PROJECT DESCRIPTION The 10.36-acre project site is located on the southeast side of Watsonville Road, south of Olive Avenue and north of Santa Teresa Boulevard in the City of Morgan Hill, (refer to Figures 1 and 2). For the purpose of discussion, Watsonville Road will be considered ‘west’ when describing the locations of characteristic features on and around the project site. The project site is bound by agricultural land and rural single-family residential development to the north, single-family residences to the east, single-family attached and multi-family housing to the south, and Watsonville Road and single-family residences to the west, (refer to Figure 3). The project site is currently developed with five single-family detached houses (Houses 1 through 5, as shown in Figure 4), a former chicken coop, a vehicle garage/storage shed, auxiliary structures, and associated infrastructure. The project involves the removal of the existing structures on-site and associated improvements, and subdivision of the property into 37 lots to allow for the phased development of 37 single-family detached houses (see Figure 5). While the application being processed is for a senior population, this analysis encompasses development of the site with single-family detached housing of any type occupied by any population. The existing General Plan designation for the project site is Single Family Medium (3-5 dwelling units/acre [du/ac]). Existing zoning for the site is R1-7,000 (APN 779-03-137 and 138) and R1-9,000 (APN 779-03-139). The number of units proposed is in compliance with the Single-Family Medium (3-5 du/ac) General Plan designation. The project applicant requests a zoning amendment for APN 779-03-139 to R1-7,000 and approval of a Planned Development (PD) overlay on all three project parcels. In the City of Morgan Hill, approval of a PD overlay is considered when it will facilitate and promote coordination of design and access, and when it will enhance

  • Exo Power Comeback Stage Free Download EXO Repackage Album to Be Released This March + Fans Hopes for Lay's Participation
    exo power comeback stage free download EXO Repackage Album To Be Released This March + Fans Hopes For Lay's Participation. After coming back last 2019 with "Obsession," EXO is set to have their repackage album expectedly this March! According to Naver's source, "EXO's repackage album release date expected in the fourth quarter of last year will be delayed to the first quarter of this year (January to March), and related performance will be scheduled for the first quarter of the year." Since the other group members will be enlisting to the military for the second half of the year, EXO will be going to less active then, and NCT and SuperM will become more active on promotions and comebacks. In addition to this, it is also expected that the members will be more focused on their individual schedules, including Kai's solo debut. Last year, Kai released a practice video for his upcoming solo album, which serves as a gift to his fans who were patiently waiting while he prepares for his solo album. The song title was called "Spoiler," and the video emphasizes Kai's powerful dance, which was posted in his Instagram account, together with the lyrics of the song. Also, Suho was rumored to have his solo debut as well, before serving in the military, it was not yet confirmed, but he was already hinting fans about his debut during their concerts and fan meet. Suho has recently wrapped up his last stage for the musical "The Man Who Laughs" co-starring with Super Junior's Kyuhyun.

  • Appendix D: Noise Element Guidelines | 366 D
    D Appendix D Noise Element Guidelines Guidelines for the Preparation and Content of the Noise Element of the General Plan The noise element of the general plan provides a basis for comprehensive local programs to control and abate environmental noise and to protect residents from excessive exposure. The fundamental goals of the noise element are: • To provide sufficient information concerning the community noise environment so that noise may be effectively considered in the land use planning process. In so doing, the necessary groundwork will have been developed so that a community noise ordinance may be utilized to resolve noise complaints. • To develop strategies for abating excessive noise exposure through cost-effective mitigating measures in combination with zoning, as appropriate, to avoid incompatible land uses. • To protect those existing regions of the planning area whose noise environments are deemed acceptable and also those locations throughout the community deemed “noise sensitive.” • To utilize the definition of the community noise environment in the form of CNEL or Ldn noise contours as provided in the noise element for local compliance with the State Noise Insulation Standards. These standards require specified levels of outdoor to indoor noise reduction for new multifamily residential constructions in areas where the outdoor noise exposure exceeds CNEL (or Ldn) 60 dB. The 1976 edition of the Noise Element Guidelines, prepared by the California Department of Health Services (DHS), was a result of SB 860 (Beilenson, 1975), which became effective January 1, 1976. SB 860, among other things, revised and clarified the requirements for the noise element of each city and county general plan and gave DHS the authority to issue guidelines for compliance thereto.

  • 3575 Mendocino Avenue Sustainable Communities Environmental
    Memo To: Amy Nicholson, Senior Planner From: Stantec Consulting Services Inc. City of Santa Rosa File: 3575 Mendocino Avenue Project Date: December 7, 2020 Reference: 3575 Mendocino Avenue Project – Errata Memorandum Stantec Consulting Services Inc. (Stantec) has prepared this Errata Memorandum (memo) to document revisions to the September 28, 2020 Sustainable Communities Environmental Assessment (SCEA) prepared for the proposed 3575 Mendocino Avenue Project (Project) under the California Environmental Quality Act (CEQA). PUBLIC REVIEW PROCESS On September 28, 2020, the City of Santa Rosa (City) circulated a Notice of Availability of the SCEA for a 30- day review and comment period by the public, and the responsible and reviewing agencies. The public review period ended on October 27, 2020. Following the completion of the public comment period, additional and continued outreach to interested parties and resource agencies took place, which resulted in minor editorial revisions to the language in the SCEA to clarify Biological and Cultural Resources mitigation measures. As such, the following memo has been prepared to document and clarify those changes. The SCEA is available for review at the City’s Planning Division, located at 100 Santa Rosa Avenue, Santa Rosa, California 95404, and online at the following URL: https://srcity.org/425/Plans-Studies-EIRs DECISION AND EXPLANATION REGARDING RECIRCULATION OF THE DRAFT CEQA DOCUMENT CEQA Guidelines Section 15088.5 states that new information added to a CEQA document is not significant unless the CEQA document is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse effect of the project or a feasible way to mitigate or avoid such an effect (including a feasible project alternative) that the project’s proponents have declined to implement.

  • 4.E Noise Introduction This Section Summarizes Information on the Noise Environment in the St
    4. Environmental Setting, Impacts, and Mitigation Measures 4.E Noise Introduction This section summarizes information on the noise environment in the St. Helena planning area and provides an evaluation of the noise-related effects of the proposed General Plan Update. The analysis considers existing and projected noise along major roadways, in addition to other noise sources in the area. Mitigation measures are recommended that address General Plan Update policies and implementing actions. The noise element of a city’s general plan is a comprehensive approach for including noise control in the planning process. It is a tool for achieving and maintaining environmental noise levels that are compatible with specific land use types. The Public Health, Safety and Noise Element of the proposed General Plan Update identifies noise-sensitive land uses and noise sources, defines areas of noise impact, and establishes goals, policies, and implementing actions to protect people from excessive noise and vibration. Setting Background Information on Noise Noise may be defined as unwanted sound. Noise is usually objectionable Noise is defined as unwanted because it is disturbing or annoying. The objectionable nature of sound could sound. be caused by its pitch or its loudness. Pitch is the height or depth of a tone or sound, depending on the relative rapidity (frequency) of the vibrations by which it is produced. Higher pitched signals sound louder to humans than sounds with a lower pitch. Loudness is intensity of sound waves combined with the reception characteristics of the ear. Intensity may be compared with the height of an ocean wave in that it is a measure of the amplitude of the sound wave.
