The following terms are defined in Chapter 2 (and are included here for reference)
FRENCH DRAIN. A trench, hole or other depressed area loosely filled with rock, gravel, fragments of brick
or similar pervious material used to collect or channel drainage or runoff water.
WATTLES. Wattles are used to reduce sediment in runoff. Wattles are often constructed of natural plant
materials such as hay, straw or similar material shaped in the form of tubes and placed on a downflow
slope. Wattles are also used for perimeter and inlet controls.
4.106 SITE DEVELOPMENT
4.106.1 GENERAL. Preservation and use of available natural resources shall be accomplished through
evaluation and careful planning to minimize negative effects on the site and adjacent areas. Preservation of
slopes, management of storm water drainage and erosion controls shall comply with this section.
4.106.2 STORM WATER DRAINAGE AND RETENTION DURING CONSTRUCTION. Projects which
disturb less than one acre of soil and are not part of a larger common plan of development which in total
disturbs one acre or more, shall manage storm water drainage during construction. In order to manage
storm water drainage during construction, one or more of the following measures shall be implemented to
prevent flooding of adjacent property, prevent erosion and retain soil runoff on the site.
1.Retention basins of sufficient size shall be utilized to retain storm water on the site.
2.Where storm water is conveyed to a public drainage system, collection point, gutter or similar disposal
method, water shall be filtered by use of a barrier system, wattle or other method approved by the
enforcing agency.
3.Compliance with a lawfully enacted storm water management ordinance.
Note: Refer to the State Water Resources Control Board for projects which disturb one acre or more of soil,
or are part of a larger common plan of development which in total disturbs one acre or more of soil.
(Website: https://www.waterboards.ca.gov/water_issues/programs/stormwater/construction.html)
4.106.3 GRADING AND PAVING. Construction plans shall indicate how the site grading or drainage system
will manage all surface water flows to keep water from entering buildings. Examples of methods to manage
surface water include, but are not limited to, the following:
1.Swales
2.Water collection and disposal systems
3.French drains
4.Water retention gardens
5.Other water measures which keep surface water away from buildings and aid in groundwater recharge.
Exception: Additions and alterations not altering the drainage path.
4.106.4 Electric vehicle (EV) charging for new construction. New construction shall comply with
Sections 4.106.4.1 or 4.106.4.2 to facilitate future installation and use of EV chargers. Electric vehicle
supply equipment (EVSE) shall be installed in accordance with the California Electrical Code, Article 625.
Exceptions:
1.On a case-by-case basis, where the local enforcing agency has determined EV charging and
infrastructure are not feasible based upon one or more of the following conditions:
a.Where there is no local utility power supply or the local utility is unable to supply adequate power.
b.Where there is evidence suitable to the local enforcing agency substantiating that additional local
utility infrastructure design requirements, directly related to the implementation of Section 4.106.4,
may adversely impact the construction cost of the project.
2.Accessory Dwelling Units (ADU) and Junior Accessory Dwelling Units (JADU) without additional
parking facilities.
4.106.4.1 New one- and two-family dwellings and townhouses with attached private garages. For
each dwelling unit, install a listed raceway to accommodate a dedicated 208/240-volt branch circuit. The
raceway shall not be less than trade size 1 (nominal 1-inch inside diameter). The raceway shall originate at
the main service or subpanel and shall terminate into a listed cabinet, box or other enclosure in close
proximity to the proposed location of an EV charger. Raceways are required to be continuous at enclosed,
inaccessible or concealed areas and spaces. The service panel and/or subpanel shall provide capacity to
install a 40-ampere 208/240-volt minimum dedicated branch circuit and space(s) reserved to permit
installation of a branch circuit overcurrent protective device.
Exemption: A raceway is not required if a minimum 40-ampere 208/240-volt dedicated EV branch circuit is
installed in close proximity to the proposed location of an EV charger at the time of original construction in
accordance with the California Electrical Code.
4.106.4.1.1 Identification. The service panel or subpanel circuit directory shall identify the overcurrent
protective device space(s) reserved for future EV charging as "EV CAPABLE". The raceway termination
location shall be permanently and visibly marked as "EV CAPABLE".
4.106.4.2 New multifamily dwellings, hotels and motels and new residential parking facilities.
When parking is provided, parking spaces for new multifamily dwellings, hotels and motels shall meet the
requirements of Sections 4.106.4.2.1 and 4.106.4.2.2. Calculations for spaces shall be rounded up to the
nearest whole number. A parking space served by electric vehicle supply equipment or designed as a future
EV charging space shall count as at least one standard automobile parking space only for the purpose of
complying with any applicable minimum parking space requirements established by a local jurisdiction. See
Vehicle Code Section 22511.2 for further details.
4.106.4.2.1 Multifamily development projects with less than 20 dwelling units; and hotels and motels
with less than 20 sleeping units or guest rooms.
The number of dwelling units, sleeping units or guest rooms shall be based on all buildings on a project site
