BACKGROUND AND DISCUSSION:
Hesse Park athletic field consists of a baseball diamond and a multipurpose field that is
used for a variety of programs, special events, youth and adult sports leagues, including
the Palos Verdes Peninsula American Youth Soccer Organization (AYSO Region 10).
At the September 20, 2016, meeting, the Council directed Staff to see if the Hesse Park
fields could be rehabilitated to enable AYSO Region 10 to play there and reduce the
impact from the closure of the Ladera Linda fields. Currently, AYSO Region 10 (younger
divisions) and BeachHead Lacrosse are using the fields at Hesse Park on Saturdays
and Sundays until November 13, 2016.
The condition of the field was impacted by the Tier II watering restrictions imposed by
California Water Service (CalWater) last year as their response to the drought
emergency declared by the Governor. The frequency and run time of the irrigation
schedule was restricted to Sunday, Wednesday and Friday. Watering was further
restricted with a water window from 8:00 PM to 6:00 AM on those days and the water
1
main can only supply a finite amount of water per minute. The system cycles through
the stations in sequence to supply the required amount of water to each station. Only
one station at a time can operate, which results in about half of the water required to
keep up with evapotranspiration (the measurement of evaporation, soil infiltration and
plant use). Prior to the water restrictions, the system could run whenever it was needed
to keep up with the needs of the turf. The improvements approved by the City Council
in 2010 (see https://s3.amazonaws.com/media.legistar.com/rpv/MeetingDate-2010-10-
05/RPVCCA SR 2010 10 05 08 Hesse and Ryan Parks Athletic Field Improvem
ents.pdf) that included regrading, deep turf maintenance and new irrigation controllers
were based on this approach.
Regrettably the drought restrictions have had negative impacts on field conditions as
the City cannot water at a level necessary to keep natural turf healthy under heavy use.
These restrictions have limited the irrigation system to operate 18% of the time when
compared to the unrestricted (except by budget constraints) water consumption.
Additional effort is now required to restore the field conditions to pre -drought emergency
conditions.
On July 31, 2016, the Tier II restrictions were lifted by CalWater, but this only removed
the cost surcharge imposed for water usage above our water budget. Unfortunately for
the turf, the watering days and water window restrictions remained in place. The
irrigation controllers were re -set to irrigate at the proper rate and Public Works extended
the time per watering days to the maximum allowable amount.
Rehabilitation Plan
The rehabilitation plan (Attachment A) is being implemented to minimize the impact on
the AYSO Region 10 and BeachHead Lacrosse while maximizing the chances of
reviving the fields before their upcoming spring season. The start date for the major
tasks shown will begin after the two fall user groups' season has concluded in
November. The proposed plan schedules the field re -opening to the public and spring
users on April 1, 2017. This may impact any user group requesting use the fields for
the spring season. The spring youth recreation sports leagues requesting field space
this upcoming season include Silver Spur Little League and BeachHead Lacrosse.
Recreation and Parks personnel will work to accommodate these requests for field
space at alternate locations (such as Ryan Park) during the turf remediation period.
The City's landscape maintenance contractor will be performing the work shown on
Attachment A at no additional cost to the City.
An order -of -magnitude cost to replace the turf field and modify the existing irrigation
system to deliver more water during the water window is estimated at $275,000 to
$400,000, depending on the extent of turf soil and drainage conditions and
irrigation/water main modifications.
ALTERNATIVES:
In addition to the Staff recommendation, the following alternative action is available for
the City Council's consideration:
2
1) Direct the Public Works to develop a full turf replacement project including
modifications to the existing irrigation system to deliver more water during the water
window days and return with a proposed project to be funded and included in the
Capital Improvement Program.
