Masterplan Review February 12, 2019

2. Aerial Map 2018
The City owns 42 acres of land known as Grijalva Park at Santiago Creek.
The land is located in the northwest corner of the intersection of N. Prospect Street and E. Spring Street with the Santiago Creek forming the western edge of the property.
The first fifteen acres were developed into a park with lighted soccer fields in This section of the park is also home to a small community building, tot lot, sand volleyball court, picnic tables, outdoor basketball courts, an outdoor exercise circuit, and walking path.

3. Grijalva 2005 Site Plan
A conceptual masterplan was finalized in 2005 for the western 27 acres
This includes ten acres of property in the creek, which will remain open space.
The plan was created through a public input process as well as with reference to the 1999 Parks Masterplan.
Based on input and priorities, the following features were included in the 2005 masterplan:
25,200 square foot gymnasium and sports center
47,300 square foot aquatic center
10,800 square foot community center
10,000 square foot skate park
Tot lot
Group picnic area
Outdoor amphitheater
Standalone restroom to support outdoor active elements on the southwest portion of the park

Community Requests
In August 2018, Marc Conner, owner of the local skate shop Contenders on Tustin Street, spoke during public comments at the council meeting, asking to raise money to build the skate park.
In October, Greater Orange Community Arts Theater (GOCAT) sent a letter to City Council asking to investigate the possibility of building and operating a community arts theater at Grijalva Park.
In November, the City Council received a letter from Orange Regional Competitive Aquatics (ORCA), a current city partner in providing swim lessons at local high school pools, requesting to explore a joint partnership to build and operate a community pool at Grijalva Park.
The City Manager received a letter of request from the Orange Public Library Board of Trustees on February 1, 2019 expressing interest in exploring opportunities for a library facility as part of the next phase of development at Grijalva Park
In addition to these four requests, there has been community discussion of potentially utilizing the property for a new east end senior center, as Orange Elderly Services continues its efforts of long term strategic planning. Copies of the three letters received are attached for reference.

Community Requests

7. Site conditions to consider: Former Union Pacific Railroad landfill
Kinder Morgan Pipeline
Residential housing
Adequate parking and circulation
Existing programming
In an effort to evaluate these requests, staff engaged the services of MIG landscape architects, formerly Purkiss-Rose-RSI, who created the 2005 masterplan to help evaluate options.
Site conditions and constraints considered in reviewing the masterplan include:
Landfill post-closure monitoring & maintenance plan
Kinder Morgan Pipeline, which runs through the north section of the property and along the current access road
Residential housing west of the creek and adjacent to the northeast portion of the property
Ability to provide adequate parking and circulation
Existing programming at the site

8. Draft Grijalva Park Updated Masterplan
Arts Theater
15,450 SF
Draft Grijalva Park Updated Masterplan
There are a variety of options that can be considered.
One option includes allocating space for all requests, with the elimination of the tot lot, group picnic area, and outdoor amphitheater. This option would require a mitigation program plan to coordinate simultaneous peak programming to ensure adequate parking. This option adds a fourth large indoor facility, which reduces the more passive informal design elements to accommodate parking and circulation.
Another option, with several variables, could include identifying two large indoor facilities, similar to the 2005 plan, with revised programming focus and square footage allocations.
Depending on ultimate parking demand, a portion of the open area and/or outdoor amphitheater may need to be reduced or eliminated to expand the parking lot.
There is a potential to achieve an economies of scale (shared restrooms and meeting space) by combining any variation of a community, senior and/or library center.
No detailed program, plans, or designs have been identified.
Based on Councils direction and input, next steps would include working with the landscape architect to determine rough magnitude costs to develop each amenity. How to manage developing shared spaces also would need to be ironed out.
It is recommended that if Council would like to proceed with exploring any or all partnerships to pursue development of the site, criteria with milestones for progress be developed for each group.
