DI.]PAR IMENT
INVOLVED:
Development lmpact Fees are fees adopted by the Citl Council based on the provisions set forth in California Government Code Section 66000-66025. These fees are assessed upon new development projects to fully or partially offset the costs ofpublic capital facilities and infrastructure that is needed to serve new demand created by development projects. The development impact fees are administralive. fire. law enforcement, library, park and circulation facilities. These fees do not pay for operation and maintenance of capital facilities, or city staffing costs. Development lmpact Fees are segregated from the General Fund and from other Cit-v budget funds or accounts containing fees collected for other purposes in accordance with accounting standards.
The California Subdivision Map Act contains specific enabling legislation for the dedication of land or fees in lieu of land dedication for neighborhood and community parks by a city, county, or special district. This legislation, codified as Government Code Section 66477, and known commonly as the "Quimby Act," also establishes the criteria for determination the land dedication requirement and in-lieu fee based on specific park standards. Developers wishing to create new residential parcels may meet the Quimby Act requirements either through direct land dedication, or payment ofan equivalent in-lieu fee.
Park impact fees are a charge to developers at the time of building permit for the cost ofpark improvements needed to serve a new development. Park Impact Fees provide up-front financing for the expansion of public facilities needed to serve a new development. Monterrey Park subdivision developer paid park impact fees prior to construct a park. The park has been completed and accepted by the city on March 6, 2024 (see exhibit "A") and now the developer is requesting reimbursement for the cost of building the park. The reimbursemenl cannot exceed the amount paid in park impact fees.

I. PURPOSE AND SCOPE
A. The City of lmperial ("City") has identified a need to equip its Community Development Staff with body-worn cameras ("BWC') as part of its continuing effort to promote transparency, protect its members from frivolous claims and increase efficiency. This policy is intended to provide Community Development Staff with instructions and guidelines on when and how to use BWCs so contacts with the public can be recorded reliably and in accordance with the law. ln the event of a conflict between any provision of this policy and a mandatory provision of any applicable law, the mandatory provision of the applicable law shall apply.
The Use of a recording system complements Community Development Staff in the performance of their duties by providing a digital record of enforcement and investigative field contacts. A recording of an event or contact also enables the delivery of timely, relevant and appropriate training to maximize safety for Community Development Staff and improve the provision of services to the community. These recordings will also protect Community Development Staff from false accusations and can be instrumental in resolving public complaints.
The video recordings captured by recording devices do not necessarily reflect the experience or state of mind of an individual Community Development Staff in a given incident. Moreover, video recordings have limitations and may depict events differently than the events recalled by the involved employees. Specifically, it is understood the BWC may capture information that may not have been heard and/or observed by the involved Community Development Staff.
