Policies

1. Policy LU-6.1 Residential amendments that increase density in the Desert and Mountain regions

   We discourage policy plan amendments that would permit new development on lots smaller than 2.5 acres in the Desert regions and lots smaller than one-half acre in the Mountain region. We approve general plan amendments that would increase residential density only if:
   • The proposed change is determined to be compatible in accordance with policies
   LU-2.1, 2.2, 2.3, and 4.5.
   • Adequate infrastructure and services are available concurrently.
   • The increase in density would not degrade existing levels of service for fire protection, sheriff, water, or wastewater service in the area.

   GO TO POLICY

2. Policy LU-6.2 Large residential development in the Desert and Mountain regions

   We require a specific plan or Planned Development process for proposed residential development in the:
   • North or East Desert regions: when the proposed development would include one or more lots that is 2.5 acres or smaller and the overall development would cover 40 or more acres.
   • Mountain region: when the proposed development would include one or more lots that is 1 acre or smaller and the overall development would cover 40 or more acres.

Policies

1. Policy H-5.2 Local organizations

   We utilize local organizations that provide fair housing services to the San Bernardino County area to better prevent, monitor, and resolve fair housing issues. We also utilize local organizations to provide housing information, counseling, and financial literacy to lower income households.

Goals

1. Goal IU-3 Stormwater Drainage

   A regional stormwater drainage backbone and local stormwater facilities in unincorporated areas that reduce the risk of flooding

   GO TO GOAL

Policies

1. Policy IU-1.7 Areas vital for groundwater recharge

   We allow new development on areas vital for groundwater recharge when stormwater management facilities are installed onsite and maintained to infiltrate predevelopment levels of stormwater into the ground.

   GO TO POLICY

2. Policy IU-1.11 Water storage and conveyance

   We assist in development of additional water storage and conveyance facilities to create a resilient regional water supply system, when it is cost effective for County-owned water and stormwater systems.

   GO TO POLICY

3. Policy IU-3.1 Regional flood control

   We maintain a regional flood control system and regularly evaluate the need for and implement upgrades based on changing land coverage and hydrologic conditions in order to manage and reduce flood risk. We require any public and private projects proposed anywhere in the county to address and mitigate any adverse impacts on the carrying capacity and stormwater velocity of regional stormwater drainage systems.

   GO TO POLICY

4. Policy IU-3.2 Local flood control

   We require new development to install and maintain stormwater management facilities that maintain predevelopment hydrology and hydraulic conditions.

   GO TO POLICY

5. Policy IU-3.3 Recreational use

   We prefer that stormwater facilities be designed and maintained to allow for regional open space and safe recreation use without compromising the ability to provide flood risk reduction.

   GO TO POLICY

6. Policy IU-3.4 Natural floodways

   We retain existing natural floodways and watercourses on County-controlled floodways, including natural channel bottoms, unless hardening and channelization is the only feasible way to manage flood risk. On floodways not controlled by the County, we encourage the retention of natural floodways and watercourses. Our priority is to reduce flood risk, but we also strive to protect wildlife corridors, prevent loss of critical habitat, and improve the amount and quality of surface water and groundwater resources.

   GO TO POLICY

7. Policy IU-3.5 Fair share requirements

   We require new development to pay its fair share of capital costs to maintain adequate capacity of the County’s regional flood control systems.

Policies

1. Policy NR-2.5 Stormwater discharge

   We ensure compliance with the County’s Municipal Stormwater NPDES (National Pollutant Discharge Elimination System) Permit by requiring new development and significant redevelopment to protect the quality of water and drainage systems through site design, source controls, stormwater treatment, runoff reduction measures, best management practices, low impact development strategies, and technological advances. For existing development, we monitor businesses and coordinate with municipalities.
