North Hollywood Parks Stormwater Capture Projects
To capture 2,912 acre-feet of stormwater each year in the San Fernando Valley, this project includes community outreach to people living near Alexandria Park, North Hollywood Park, and Valley Plaza Park North and South in North Hollywood. These parks are adjacent to the Tujunga Wash and the 170 Highway. In Collaborations with the engineers, location for the underground stormwater capture systems where established in the parks. One of the main factors was disturbing as few trees as possible while mitigating replacement and new trees. The irrigation system was redesigned to improve water use efficiency, precisely addressing the soil conditions with healthy watering patterns to help mature trees resist diseases and pests.
Some of additional improvements include the addition of drought tolerant landscaping, walking trails, fitness stations and hydration stations.

Alexandria Park
Alexandria Park is a small neighborhood park cherished for its trees and grassy fields. A robust tree evaluation was conducted to determine the health and age of all existing trees. Few trees will be removed, and will be mainly trees that are in decline. These trees will be mitigated with the addition of dozens of new trees to maintain the small but important urban forest in this park. Existing oak and sycamore groves will be protected during construction. A new shared access road and decomposed granite trails will provide new walking opportunities and connection to the future greenway. Existing picnic tables north of the park will be improved and protected during construction.
North Hollywood Park
North Hollywood Park, bisected by Magnolia Boulevard, offers numerous recreational amenities to visitors on both sides of the park. A robust tree evaluation was conducted to determine the health and age of all existing trees. Trees in decline and those within the footprint of the underground stormwater facilities will be removed and mitigated with new trees across the site. Parking lots will be renovated to accommodate new shade trees, drought tolerant landscape, and permeable pavement surfacing. Additional park improvements include: renovated fitness trails, 3 new baseball fields, hydration stations, and a retrofitted irrigation system utilizing recycled water.
Valley Plaza Park North
Valley Plaza Park North is admired for its picturesque trees and grassy fields. A tree evaluation was conducted to determine the health and age of all existing trees. Over 90 new trees will be installed across the park, chosen to improve the distribution of age and appropriateness for a warming climate. Few trees will be removed, and will be mainly trees that are in decline. Existing groves of large, shade providing tipu, oak, and sycamore trees will be protected during construction. Additional trees will be planted across the site to mitigate tree removal and provide more groves of trees, supported by a retrofitted irrigation system. This section of Valley Plaza Park will have resurfaced fitness trails and upgraded fitness stations.
Valley Plaza South
Valley Plaza Park South is admired for its picturesque trees and grassy fields. A tree evaluation was conducted to determine the health and age of all existing trees. Over 70 new trees will be installed across the park, chosen to improve the distribution of age and appropriateness for a warming climate. Few trees will be removed, and will be mainly trees that are in decline. Many mature, shade-providing trees will be protected. New, drought tolerant shrubs will be installed throughout the parking lot and around the existing tennis courts. The parking lot will be refurbished and restriped and will include permeable pavement and new shade trees. A new walking path will improve pedestrian circulation.
