Animal Assisted Happiness Smile Farm Project at Baylands Park

Notice is Hereby Given that the City of Sunnyvale has prepared an Initial Study to evaluate the environmental impacts of the proposed Animal Assisted Happiness Smile Farm Project, described below, and intends to adopt a Mitigated Negative Declaration in accordance with the California Environmental Quality Act. The Initial Study concludes that the proposed project would not have a significant adverse effect on the environment if the mitigation measures identified in the Initial Study are adopted and made conditions of approval of the proposed project.

Location of Project: Baylands Park, 999 East Caribbean Drive, Sunnyvale, CA 94089

Summary Project Description: The project applicant, Animal Assisted Happiness, a Registered 501(c)(3) non-profit, is proposing the Animal Assisted Happiness Smile Farm Project (proposed project) that would involve the construction and operation of a therapeutic animal facility, or Smile Farm, for children with special needs, on a 2.5 acre site located in the northwest portion of Baylands Park in Sunnyvale. The proposed project would involve minimal grading and site preparation for 14 new structures, most of which would be prefabricated. The total building footprint would cover 2,239 square feet. The proposed project would retain the former Recycled Water Test Garden located on a portion of the site and would not necessitate the removal of any existing live trees.

Public Review Period: The Initial Study and proposed Mitigated Negative Declaration are available beginning July 8, 2016 and ending July 27, 2016. The documents can be viewed:

Comments on the Mitigated Negative Declaration must be submitted in writing no later than 5:00 p.m. on July 27, 2016 and sent by mail:

The City of Sunnyvale (City) owns and operates the Donald M. Somers Water Pollution Control Plant (WPCP), which provides treatment of wastewater flows and loads for 148,000 residents and business people from domestic, commercial, and industrial sources in Sunnyvale, Rancho Rinconada, and Moffett Field. The WPCP includes an approximately 16.6‐acre main plant and two 440-acre oxidation ponds. The WPCP was originally constructed in 1956. With the enactment of the Clean Water Act in 1972, more restrictive water quality standards were established, leading to expansion and process upgrades to the WPCP. In 1978, the City added tertiary treatment to WPCP operations. Currently (2016), the WPCP processes about 14.5 million gallons per day (mgd) average dry weather flow and some of the WPCP's components are reaching the end of their useful life.

Much of the wastewater system's aging infrastructure needs replacing. Fortunately, the City is well into its planning for the future. While age is a major driver for the City's Water Pollution Control Plant Master Plan, other factors include the need for operational reliability, increased capacity, new regulations and innovative technology that will rebuild the system over the next 20-plus years. All these improvements encompass the Sunnyvale Clean Water Program, which is the City's long-term capital improvement program to renovate the Plant through a series of projects and upgrades.

Old Mountain View-Alviso Road Bridge Replacement Project

The Old Mountain View-Alviso Road Bridge has been in service since the 1960's and spans Calabazas Creek. Although the bridge is regularly inspected by the California Department of Transportation (Caltrans) and maintained by the City of Sunnyvale, it is in need of substantial rehabilitation to maintain existing service. The proposed project includes construction of a replacement bridge to correct existing structural and roadway deficiencies at the project site.

The replacement bridge will be constructed on the same alignment as the existing bridge and will consist of a three span bridge approximately 125 feet in length and 52 feet in width. The bridge will include two 12-foot wide traffic lanes, two 7-foot wide shoulders/bike lanes, two 6-foot wide sidewalks and two 1-foot thick barriers.

None of the proposed work on Old Mountain View-Alviso Road will result in the relocation of the existing driveways that serve the surrounding businesses.

In order to minimize the duration of construction, as well as to reduce the footprint of the project and its effects on Calabazas Creek, Old Mountain View-Alviso Road will be temporarily closed to vehicular, bicycle and pedestrian traffic between Reamwood Avenue on the west and Patrick Henry Drive on the east. Traffic will be temporarily detoured to Tasman Drive via Reamwood Avenue and Patrick Henry Drive. The Calabazas Creek Trail will be temporarily closed between Tasman Drive to the south and SR 237 to the north. Trail users will be detoured along the surrounding surface streets during construction of the bridge replacement. Appropriate detour signage will be provided.

Construction of the proposed project facilities is expected to occur in summer 2017. Construction work will typically be done within normal City working hours. It is anticipated that the road closure will extend for approximately three months, and trail closure will extend for approximately four months, while the new bridge is being constructed.
