9.2 MAINTENANCE AND OPERATIONS REPORT PARKS MAINTENANCE BY: BRENT SCROGGS, PROGRAM MANAGER – In addition to on-going basic maintenance in the parks including playground maintenance, irrigation checks, and ballfield maintenance, staff has been working on the following projects this month: REOPENING OF PLAYGROUNDS On Friday, October 2nd, staff opened all playgrounds throughout the City based on the updated State of California guidelines allowing playgrounds to reopen in Contra Costa County, with modified protocols. The modified protocols are shown on signage (shown below) at each playground and include wearing of face coverings for anyone over the age of 2; parental/caregiver monitoring that children are maintaining six (6) feet of social distancing for members of different households; and washing or sanitizing patron’s hands before and after enjoying the play equipment. Prior to opening, staff thoroughly cleaned all playgrounds with a diluted Pine Sol solution, as well as placed signs at all entrances to playgrounds. Staff removed all caution tape that had previously restricted residents from using the playgrounds and had all playgrounds open by 10 a.m. Public Services staff will continue to clean playgrounds 3-5 times per week and monitor all signage.

WINDEMERE RANCH MIDDLE SCHOOL CRICKET PITCH RENOVATION Public Works staff recently completed modifications to the cricket pitch located at Windemere Ranch Middle School. Due to the heavy usage of the cricket pitch, the turf on the run up area had worn out and become muddy and difficult to play on. Staff removed approximately 10 yards of material and added a decomposed granite base with a top layer of infield mix. The added material was leveled and compacted to create an acceptable playing surface. Staff was able to use the turf that was cut out to fill in the edges of the new playing surface. Minor adjustments were made to the irrigation system to prevent water from directly spraying on the new playing surface eliminating puddles and wet spots.

CENTRAL PARK SOCCER FIELD RENOVATIONS With the closure of all sports fields in Central Park for annual renovations, on November 2nd, Public Works staff began renovating Soccer Field #1. In order to start with a clean surface, staff tightly mowed the turf; located and marked all irrigation heads, valves, and drains; and used the Verti Cutter to remove the dead thatch. Staff removed all loose thatch and debris and mowed the turf down to 1” to clean up any leftover loose materials. The last step was to add starter fertilizer and seed followed with topdressing of a treated redwood mulch and sand blend. The new seed will begin germinating within a month in the worn areas of the fields. All fields will remain closed until March 2021, giving them the necessary time to recuperate from damage that occurred during the soccer season.

ATHAN DOWNS BASEBALL FIELD #3 BACKSTOP REPLACEMENT

On Monday, September 28th, crews from Chain Link Fence Supply began the process of removing the existing backstop on Baseball Field #3 at Athan Downs Park and completed the project on Thursday, November 18th. This project was funded by CIP #955584. The backstop is the original backstop installed when the park was built in the late 1970’s. The new backstop will match Fields #1 and #4, which also have been replaced in the past few years. The new backstop has a much more effective design to help prevent balls from flying over the fences and possibly injuring those that are watching the games. Once the original backstop was removed, crews from JD Concrete removed the existing concrete border and installed new concrete to match the new backstop. Chain Link Fence Company then returned and installed the new backstop. This new backstop will be more consistent with the other backstops at Athan Downs, as well as the remainder of the baseball fields throughout the City.

MEMORIAL PARK DRINKING FOUNTAIN REPLACEMENT Public Works staff replaced one of the original drinking fountains at Memorial Park the week of November 16th. The existing drinking fountain was cut out using a torch so the concrete would not have to be broken out. Staff then placed the new drinking fountain in place and anchored it to the concrete using new concrete anchor bolts. The new drinking fountain is ADA compliant for wheel chairs and also has a dog fountain. This is the first of three fountains that will be replaced in the upcoming weeks at this location.

FACILITIES MAINTENANCE BY: SANDY MARTIN, PROGRAM MANAGER – SAN RAMON COMMUNITY CENTER- LEAKING FIRE SPRINKLER The Parks and Community Services staff noticed water seeping through the eastern wall in the Alcosta Room of the San Ramon Community Center and contacted Public Works staff. While the wet sheetrock confirmed where to begin looking, the City’s Flir (thermal imaging camera) guided staff to where the leak began. Staff opened up an exploratory hole in the ceiling and found the source of the leak. A pipefitting had started to drip and the water followed the room construction across the ceiling and down the wall. Because it is connected to the fire sprinkler system, the pipefitting needed to be replaced by a certified company. The City’s fire system inspection and repair company, Fire Protection Specialists, made the sprinkler repair. Once the sprinkler repair was made, Public Works staff patched the hole and repainted the ceiling. Parks and Community Services staff were temporarily relocated while the repair was made.

IRON HORSE GYM SCOREBOARDS The FY 2019/20 CIP #5515 included the replacement of the scoreboards located at the Iron Horse and Pine Valley Gymnasiums. Both scoreboards were original to the facilities and were constantly broken. Several of the digits were no longer operable, and the remaining parts were becoming difficult to obtain. In addition, if the scoreboards could be repaired, staff would have to remove the part, mail it to the authorized repair shop, and await its return by mail. Staff determined that it would be beneficial to request funding to replace the units. The scoreboards arrived the last week of September, and staff completed the installation of the scoreboards at Iron Horse Gym on October 7th and began the installation of the scoreboards at Pine Valley Gym, which were completed the week of October 12th. The new scoreboards are an upgraded system and are completely LED and wirelessly connected. Once programming for both the City and District has resumed, they will be able to enjoy these new scoreboards.

SAN RAMON OLYMPIC POOL AND AQUATIC PARK (SROP) – 50M MANIFOLD REBUILD Due to their expertise and experience, Public Works staff Aquatics group recently re-built the 8” recirculation manifold for the 50M pool at SROP. The San Ramon Olympic Pool and Aquatic Park Renovation Project CIP# 200006 included the removal of the Little Squirt slide. The slide served the pool’s patrons for many years, but it was aging and parts were no longer available. As part of the replaster component of CIP #200006, the slide was removed. The 8” recirculation manifold served both the 50M pool and the slide. With the slide removed, staff reconstructed the manifold in accordance with the Uniform Plumbing Code. Now that the manifold only serves the 50M pool, staff can now install a proper flow gauge to monitor the pool’s recirculation.

WINTER PREPARATIONS Public Works staff has been diligently visiting each of the City’s 16 facilities to ensure that they are prepared for any rain that may occur during the winter months. Rain gutters have been cleaned and repairs to any visible damage have been made. Roof drains and downspouts have been cleared of debris. PINE VALLEY MIDDLE SCHOOL GYMNASIUM – BROKEN WINDOW On Wednesday, November 4th, Public Works staff was notified by the San Ramon Valley Unified School District (SRVUSD) that a window at the Pine Valley Middle School Gymnasium had been broken. Staff could not find any evidence to determine what may have caused the damage. According to the Master Use Agreement between the City of San Ramon and SRVUSD, the City is responsible for routine maintenance of the facility. Staff evaluated the window and discovered that the broken window is a security window with embedded mesh located on the northwest corner of the building. Staff requested that All American Glass in San Ramon evaluate and provide a replacement cost. They were on site on Monday, November 9th to measure and order a replacement. In the interim, staff has taped the window for safety and, should the need arise, will board the window until the replacement pane can be installed.

SAN RAMON LIBRARY EMERGENCY BACK-UP BATTERY REPLACEMENT While performing a routine light check at the San Ramon Library, Public Works staff noticed that the emergency lighting system was not energizing. This emergency system is intended to automatically supply illumination to designated areas and equipment in the event of a power failure. There are 16 batteries operating the system at the Library and they were installed when the building was renovated in 2016. The typical life span of these batteries is 3–5 years. Staff determined that the batteries were no longer functional and ordered replacements. Staff installed the replacement batteries the week November 16th.

SAN RAMON LIBRARY LED DRIVER REPLACEMENT On Monday, November 16th, Public Works staff was notified that the San Ramon Library sign facing Bollinger Canyon Road was not illuminating. Staff investigated and found that the LED driver was no longer working. A new driver was ordered and subsequently installed on November 18th.

DOUGHERTY VALLEY AQUATIC CENTER WINDSCREEN The Public Works facilities staff installed 180 linear feet of windscreen on the perimeter fence of

the Dougherty Valley Aquatic Center the week of November 16th. Due to the location and

elevation of the Aquatic Center, the facility is subjected to high winds. This windscreen will

assist with limiting debris and leaves from blowing through the fence and into the 50-meter pool.

The leaves and debris build up in the gutters and prevent the pool from recirculating and filtering

the pool. When the build-up occurs, the water level rises and, on several occasions, has caused

the pool to overflow. The windscreen will help alleviate overflow situations and eliminate

approximately ten (10) hours per week the staff spends on removing debris from the pool.

DOUGHERTY STATION COMMUNITY CENTER TURF The lifecycle of a variety of beetles are now in the grub stage. Have you ever encountered little white “C” shaped creatures while digging in your garden or lawn? If so, you have encountered a grub. Grubs are the larvae of many different varieties of beetles, including the Japanese Beetle. Grubs have a voracious appetite and feast on the organic matter in your soil – including the roots of plants and turf. Right now grubs are trying to eat as much material as possible before moving deep into the soil to spend the winter. When the ground warms, the grubs move back to the surface and emerge as beetles. Unfortunately, grubs are tasty treats to some of our local wildlife. Night Bandits, or more commonly, raccoons, enjoy feasting on the plump grubs. Because the roots of the turf have been devoured, it is easy for the raccoons to peel back the turf to expose and eat the grubs. Raccoons are not the only local wildlife that enjoys a good grub feast; skunks and birds will also peel or remove patches of turf to feast on grubs. The photos below were taken in the courtyard located behind the Dougherty Station Community Center. Based upon the evidence, it appears those night bandits found a group of grubs and rolled the turf in order to enjoy the feast. Staff submitted a work order to the

City’s landscape contractor and the area has been treated. The turf was fertilized to re-establish the root base and the area will be monitored for overall health.
