Collier Park is the oldest of La Mesa's parks and until 2017 renovation of the "panhandle" entrance at Palm & Pasadena, has not had any upgrade since the 1990's, other than resurfacing the 1950's court to add pickleball lines in 2014. The planned renovation of this neighborhood park is part of a long term project to improve and update the park based on community input through a master plan started in 2008, adopted in 2013, with additional input gathered in 2018. Surveys reflected a number of community interests: including tennis, playgrounds, safety and pickleball.
The next phase of improvements, with an estimated cost of $2.4 million, is being completed with funding that has been allocated from park development fees, Federal Community Development Block Grants (CDBG), La Mesa Park and Recreation Foundation donations (for the new playground), and CA Proposition 68 Land and Water Bond funds. The project includes: replacing the restroom, court and playground: improving the topography to improve interests park drainage, visibility, and creating ADA accessible access throughout the park: installing security cameras, lighting, parking, picnic shelters, pathways/sidewalks, and plazas: park drainage, and adding landscaping, including a mix of turf, low water vegetation, and storm water quality features. To accommodate these improvements some areas of the park will have a grade change from its existing levels. The renovation project is scheduled to go out to bid in early 2021, with construction anticipated to take place next summer/fall which will require closing the current park and courts..
