2013 Water System Plan, Volume II - Seattle City Clerk's Office - City ...

Chapter 5 Water Infrastructure
5.9.6 Standby Power
Consideration should be given to the need for dedicated standby power and in some cases
standby power may be required for some types of projects/facilities for continuous operation.
Alternatives to dedicated standby power may be considered by the reviewing authority with
proper justification. At a minimum, a power receptacle to the switchgear is required for the
connection of a portable generator. Powered equipment and controls critical for water storage
facility operation should be capable of using standby power. For more detail on standby power,
see DSG Chapter 9, Electrical Design.
5.9.7 Multi-Use Facilities
Where a storage facility is to be integrated with other recreational uses (e.g. tennis or basketball
courts), grass-covered recreational areas, or parking lots special consideration should be given
to physical and sanitary security issues. Storage facility design should address the following:
Locate hatches to storage cells and valve chambers that are physically separate and
secure from public areas, but visible from adjacent streets to enable observation by
law enforcement or security personnel.
Provide physical security to intrusion for hatches, tank ladders and doors to valve
chambers or other enclosures.
Provide appropriate signs that clearly indicate areas that are for authorized
personnel only.
Provide lighting fixtures and features that give the necessary level of lighting for
security without negative impacts to adjacent public areas. Lighting fixtures should
be designed so that the wiring and/or bulbs are not exposed or easily accessed to
preclude inadvertent damage or vandalism.
Refer to the current agreement between Seattle Parks and Recreation and SPU for specific items
associated with multi-use reservoir sites. Contact Kim Serwold at kim.serwold@seattle.gov.
5.9.8 Landscaping and Weed/Pest Control
For detailed information on landscaping and weed and pest control, see DSG Chapter 4, General
Design Considerations.
5.9.9 Access and Security
For detail on site access and security, see DSG Chapter 15, Physical Security.
5.9.9.1 General
The following are general considerations:
Include SPU Security Plan requirements for general security and security design
requirements for water facilities.
If the storage facility site is not open for public use, provide a means of controlled
access around the entire perimeter. If the site will be open for public use, provide a
means of controlled perimeter access around the hatches, vents and vaults.
