The Skyline Area Master Plan (“the Plan”) is a living document shaped by community input and shared values. The Plan's vision is to preserve the 292 acres of the Skyline area in its natural state for the benefit of current and future generations while providing a few simple amenities to enhance public enjoyment, accessibility, and visitor experience.
The Plan also establishes a strategic approach for the upkeep and enhancement of the meadow, nearby trails, and connections to regional trail systems, including access to the Cleveland National Forest. The Plan is organized into five main sections:
1. The Vision and Framework section outlines the goals and structure of the plan.
2. The Background and History section details the acquisition and development of the Skyline area over time.
3. The Planning Process section discusses the procedures for developing the Plan and methods of obtaining information to form recommendations.
4. The Recommendations section outlines proposed improvements for the area, maintenance and fire prevention standards, and policies and procedures to ensure for the long-term care of the area.
5. The Implementation Plan section details the proposed projects for the Skyline area over the next three-year period.
2.0 Background and History
The Skyline Area is comprised of approximately 292 acres of land, situated on the southernwesterly border of Corona, California, between Foothill Pkwy. and the Cleveland National Forest (Figure 1.).
Skyline is the city’s most popular hiking destination and is readily accessible to the public. The area is surrounded by nature and is a gateway for hikers and mountain bikers to access the Cleveland National Forest.
5 Figure 1. Area map
The Plan focuses on the land owned by the City of Corona, (Figures 2 and 3) which is comprised of the meadow south of Skyline Drive and the hillside area located between Skyline Drive and Foothill Parkway. Surrounded by hillsides and etched with canyons, this area provides stunning views from multiple vantage points and is celebrated for its natural beauty. 6 Figure 2. Subject Property
Figure 3. Skyline Meadow
7 2.1 Property Annexation
The Skyline area was historically designated as an agricultural preserve in the County of Riverside and contained two dwellings with an on-site earthen reservoir for agricultural irrigation purposes.
Two natural drainage courses are situated through and adjacent to the site (Annexation 105). The zoning included Open Space on the easternmost 20.85 acres of the site, and Single Family Residential with minimum 9,600 square foot lots on the remaining 39.16 acres. The pre-zoning of the site was a prerequisite for LAFCO to consider the annexation to the City. At the same time, the property to the north of Skyline Drive, known as Orchard Glen, was being developed with single family homes on minimum 7,200 square foot lots.
In 2020, Knowlton Communities proposed a housing development on 39.16 acres of the Skyline meadow area that consisted of 63 single-family homes, with 20.85 acres of the meadow remaining as open space. This project caused concern in the community. It would have blocked public access to the trails that led to the Cleveland National Forest and generated a significant amount of vehicular traffic through the adjacent Orchard Glen neighborhood.
On December 2, 2020, the City Council announced the City’s purchase of 292 acres in the Skyline area, which included the area proposed for development by Knowlton Communities. Per the City’s Press Release, “With this once in a lifetime legacy project, Corona will nearly double its open space, adding to the current 391 acres of open land.” The land acquisition was paid for with $2.5 million in park development funds, and $4.14 million from the General Fund and consisted of three parcels:
APN Size (acres)
275-090-013 62.36
275-070-010 228
275-090-011 1.64 Skyline Dr. dedication
This acquisition helped raise the City’s level of service from 2.5 acres of parkland per 1,000 residents to over 4 acres of parkland per 1,000 residents, surpassing the standard set in the 2020 Corona General Plan of 3 acres of parkland per 1000 residents. Furthermore, the acquisition improved resident access to parkland and amenities in this quadrant of the City, which has lower access to these services than other areas of the City.
While the City owns the meadow and adjacent land, access to and maintenance of the Skyline area involves coordination with other government agencies with their respective policies and procedures. The United States Forest Service (USFS) maintains the gate on Skyline Drive, Hagador Canyon Trail, Tin Mine Canyon Trail, and most of the land to the west and South of the City’s property. The Riverside County Transportation Department (RCTD) is responsible for maintaining Skyline Drive (as a road) from the Corona boundary to the Orange County line.
Most visitors to the Skyline area use Skyline drive for hiking and biking, but RCTD maintains it a limited-access road to be used by USFS maintenance vehicles and easement owners. 8 2.2 Corona Strategic Plan
The 2021-2026 City of Corona Strategic Plan sets forth a vision for Corona to be a safe, vibrant, and family-friendly community. The Strategic Plan contains two recommended actions for the Skyline area under the goal of Sound Infrastructure: 1) Develop a plan for the use of the newly acquired [Skyline] wilderness space that fosters outdoor recreation activities, in addition to creating formal trailheads; and 2) Create better parking facilities that provide security for vehicles left while residents hike or play. This Plan addresses both issues with recommendations based on community outreach and stakeholder input to improve the Skyline .
2.3. 2020-2040 Corona General Plan
9 Figure 4. General Plan Zoning
The 2020-2040 Corona General Plan (General Plan) is a comprehensive planning and land use document for the City of Corona. The General Plan originally designated the Skyline area as part of Annexation 105, which annexed 60.01 acres from Riverside County to the City of Corona. In April 2006, a General Plan Amendment converted 39.16 acres of the land from a Rural Residential to Low Density Residential (LDR) land use designation, and the remaining 20.85 acres was converted to Open Space/General (OS/G). Along with the General Plan Amendment was a Change of Zone, which allowed for parkland use in this area.
The General Plan’s Vision and Land Use Policies that apply to this Plan are listed in Appendix A.
2.4 Parks and Recreation Master Plan
The Parks and Master Plan (PRMP), adopted in 2024, provides a guide for the provision, improvement, maintenance, and funding of parks, recreation facilities, and programs in the City of Corona. The PRMP divides Corona into four quadrants, with Ontario Ave. and Main Street primarily serving as the dividing lines between each quadrant. The Skyline area is located within Quadrant 4.
The Quimby Act encourages a minimum of 3 acres of parkland per 1,000 residents.
Correspondingly, the 2020-2040 Corona General Plan establishes the same level of service (LOS) standard. Without the Skyline area, Corona’s LOS is 2.42. However, with the acquisition of the 292 acres of the Skyline area, along with other undeveloped parkland, Corona’s LOS exceeds the General Plan standard with 4.0 acres per 1,000 residents. 10 The PRMP discusses the Skyline Area and the need to “Create a plan that identifies the types of improvements and amenities to include at Skyline, while stewarding and protecting the site’s natural resources. The plan will be developed by city staff and include public engagement and surveying with Corona residents and the neighboring community. Specific features of the site and project costs will be dependent on the outcome of the planning process.”
2.5 Trails Master Plan
The Trails Master Plan (TMP), approved in February 2024, is a comprehensive planning document that creates a framework to guide the development and access to trails in the City of Corona. The TMP reviewed existing trails and identified new opportunities to build and incorporate off street active transportation connections throughout Corona. It provides policy recommendations, prioritized projects, and a 10-year implementation plan.
The development of the TMP included an origin and destination analysis for the Skyline area, which showed that, in 2023, 74% of total trips to/from the Skyline Drive trailhead occurred between Corona or neighboring cities such as Norco, Eastvale and Riverside. 61% of the total trips occurred within Corona, 2% to/from Norco, 4% to/from Eastvale, and 7% to/from Riverside. The Skyline Drive Trailhead had the highest percentage of activity (56%) during the winter season (January-March), and the majority of trail users (53%) accessed the trailhead during the weekends and in the morning between 6 am and 12 pm. Despite the regional draw of the Skyline Drive trailhead, the data showed that majority of the trail users are local residents who live in and around Corona and use the trail multiple times per week.
The TMP identified 5 high priority trail projects in Corona, with Skyline Drive listed as the #3 project in the implementation plan. The Skyline Drive project highlights the need for new standard trailhead amenities, including shade, benches, trashcans, water fountain, bike repair station and kiosk/signage.
During outreach for the TMP, many community members commented that the Skyline Trail tends to be the most crowded trail in Corona, and that parking is difficult in this area. Community members expressed a desire for designated parking for the trail and indicated they would like to see Skyline better maintained, with more trash facilities, regular clean-ups, and amenities such as restrooms at the trailhead.
The TMP also highlighted the opportunity for the Skyline area to formalize access to the Hagador Canyon and Tin Mine Canyon Trails, both of which branch off from the Skyline Trail. To support this, the TMP recommends improving the pedestrian bridge to Hagador from the trail entrance on Skyline Drive.
2.6 Skyline Resolution
On July 3, 2024, the City Council adopted Resolution 2024-076 to reaffirm the City’s original intent for the Skyline area. The Resolution declares the Council’s desire to preserve the 292 acres of the Skyline Trail Area in its natural state, with allowances for minor amenities to enhance public enjoyment and accessibility. It states that these minor amenities may include, but are not limited to, pedestrian bridges, seating, shade structures, trail markers, and signage. 11 3.0 Planning Process
The process to develop the Skyline Area Master Plan included conducting an inventory of existing trails in the Skyline area, administering a balanced citywide survey to identify desired amenities, and participating in several outreach events to discuss residents’ priorities for the Skyline area.
This approach helped ensure the Plan represents the interests of the entire city and is shaped by community input and shared values.
3.1 Skyline Trail Inventory
Figure 5. Major Trails in Skyline Area.
A comprehensive assessment and documentation process was conducted for all existing trails within the Skyline area. This included a review of the TMP and Trails Inventory, on-site visits, public outreach, collaboration with volunteers and trail enthusiasts, and a review of publicly available data from popular trail user platforms such as Strava, ESRI Survey 123, Ride with GPA, Avenza Maps, and AllTrails. This information was compiled into a detailed GIS map, which is shown in Figure 5. The map provides essential trail information, including trail locations and difficulty levels.
The Skyline area contains several trails of varying styles and uses. The primary and most popular route is Skyline Drive, which is a dirt road, maintained by Riverside County, that connects to the Cleveland National Forest (CNF) network. There are two official CNF hiking trails: Hagador 12 Canyon, and Tin Mine Canyon. The meadow area has a patchwork of trails through the center and a main trail that circumnavigates the perimeter. The majority of the trails throughout the hills were created from fire breaks (e.g. Skinsuit Trail) or by the mountain bike community (e.g. Block, Troy Lee).
Skyline Drive and the surrounding area is widely used but lacks standard amenities. The amenities that do exist are located primarily at access points, either along Foothill Parkway (water fountain, trashcans, wayfinding signage) or at Burrero way (bike repair station, informational kiosk, accessible parking, trashcan).
This area is very popular among the hiking and mountain biking communities because it is easily accessible and has a large number of trails. The best marked trails are Tin Mine and Hagador , which are primarily used for hiking. There are approximately 20 single-track trails that were developed over time and are well documented online (e.g., Strava) but do not have physical wayfinding markers. Many of them are very steep and have blind turns, which creates safety concerns and conflicts with hikers and mountain bikers. As displayed in Figure 5, most of the trails have the IMBA rating of double black diamond or “Extremely Difficult”. While the Skyline area is frequented by users for these difficult trails, easier trails are less well-known or developed.
There are various features in the area that are widely utilized but could be improved to increase accessibility while retaining the natural character of the area. For example, in order to get to the Hagador Canyon trailhead or the meadow, visitors must either cross a steep wash or cross a makeshift log bridge. Certain trails, such as the unnamed trail accessing the land directly to the east of the meadow, become exceedingly steep and require hikers to climb on all fours to reach the top. While easy walking circuits exist in the meadow area, none are marked with wayfinding signage for route distance or direction.
3.2 Survey
The City conducted an online survey from July 4 to August 30, 2024, to gauge residents’ perceptions of the Skyline area, understand their priorities, and identify opportunities for improvement. In order to balance the needs and feedback of all Corona residents, survey respondents were invited to participate in the survey in one of three ways:
1. Open Participation: This survey method allowed any interested individual to participate by utilizing a http link and QR code that directed potential respondents to the survey site.
To maximize engagement, the survey was advertised a variety of ways, including on the City’s website, through social media, in the Community Services Insider and Corona Connection, through flyers distributed at local stores, and at city events such as the Summer Concert Series and popup events at the Skyline Drive trailhead.
2. Random Sample: This method distributed the survey to a random sample of 1,000 Corona residents drawn from a list of citywide addresses of single-family and multi-family households with known email addresses. The survey was provided in an email invitation to each resident and was verified to be reasonably geographically distributed throughout the city prior to distribution.
3. Orchard Glen Residents: Due to their proximity to the Skyline area, the perceptions of the Orchard Glen residents were of particular interest as their neighborhood is directly 13 adjacent to the Skyline meadow. All 108 households from the Orchard Glen neighborhood were emailed an invitation to participate in the survey.
Figure 6. Skyline Area survey.
Respondents were provided a brief introduction to the survey (Figure 6.) and asked four questions about the Skyline Area:
1. What do you love about Skyline?
2. How would you improve Skyline?
3.What amenities would make Skyline better?
4.Is there anything else you would like to add?
A total of 1,195 participants completed the survey, of those 1,195 responses, 67 were from the random sample, and 20 from Orchard Glen completed the survey. A summary of the responses is provided below, and a more extensive breakdown of the survey results is provided in Appendix B.
What do you love about Skyline?
The first question on the survey was “What do you love about Skyline?” and included an open text box that allowed respondents to write in whatever response they wanted. Figure 7 (below) is a word cloud for the responses, with the larger font representing the most frequently used words. 14 Figure 7. Word cloud with most frequent words for “What do you love about Skyline?” 261 responses stated that Nature and Open Space were what they loved the most. The variety of trails, hiking and bicycling were the next most frequently mentioned responses, with 247 comments. The fact that it is close by, and you can easily get access to nature from your home, was third with 221 comments. The great views, scenery and natural beauty were mentioned fourth with 180 comments. Other items that were commonly mentioned were: exercise and variety in skill levels (70), cleanliness (34), peace and quiet (34), easily accessible and easy for strollers (28), open to the public (17), please leave it natural (19), and easy access to the forest (13).
When analyzed separately, the random sample of citizens throughout the city most frequently noted nature and open spaces (25), with being close by as second (10) most common response.
The respondents from Orchard Glen indicated nature and open spaces as what they love (9) with the variety of trails, hiking, and biking as second (3).
How would you improve Skyline?
The second question on the survey was “How would you improve Skyline?” Respondents were provided an open text box and allowed to write whatever response they wanted. Figure 8 (below) is the word cloud for all of the responses, with the larger font representing the most frequently used words.
Figure 8. Word cloud, most frequent words for “How would you improve Skyline?” Safe parking and enhanced security measures, including patrols, signage, and cameras, were highlighted as concerns (137). Additional parking (118), shade (117), seating (93), and water 15 fountains (85) were widely requested. Community feedback also highlighted strong support for adding restrooms (185), though some opposed their inclusion (7), with opinions varying by location of the survey respondent. Issues with litter (74), dog waste (61), and trail maintenance (63) were also recurring themes, with calls for improved cleaning (23) and trimming of overgrowth (63). Many requested more trail signage (64), including difficulty markers (6), interpretive signs (26), and mile markers (30).
While the majority advocated for some improvement, a number of respondents expressed a desire to leave the area as it is (64). Other suggestions included connecting trails with a bridge (27) and creating easier trails (18) for less experienced users. Overall, the feedback between the three sample sizes were very similar, with the Orchard Glen residents skewing slightly more for minimal changes.
What amenities would help Skyline be even better?
The third question on the survey was “What amenities would help Skyline be even better?” Respondents were provided a list of 12 specific amenities and an “other” option with a text box for a write-in response. Participants were allowed to select as many options as they wanted.
The results are presented in Table 1 (below), arranged by the highest percentage of support from the largest respondent group, the open participation group. The survey revealed varying preferences for amenities across the three survey groups.
Restrooms were the most desired feature overall, with strong interest from the Open (62%) and Random (67%) samples, but lower support from Orchard Glen residents (25%). Water fountain, trail maps, and trail signage were all highly requested amenities (over 50%), following a similar trend of greater support by the Open and Random groups than the Orchard Glen group. Other amenities had varying levels of support and are represented in Table 1 (below). 16 Table 1. Desired amenities by respondent groups.

More Bike Trails 23% 26% 15%
Other 13% 12% 20%
Overall, restrooms, trail maps, trees, trail signage, and a water fountain ranked as the highestpriority improvements by the overall community.
Is there anything else you would like to add?
The last question on the survey was “Is there anything else you would like to add?” Respondents were provided an open text box and allowed to write whatever response they wanted. Figure 9 (below) is the word cloud for all responses, with the larger font representing the most frequently used words.
17 Figure 9. Word cloud, most frequent words for “Is there anything else you would like to add?”
The most frequent responses were variations or repeats of answers previously provided on the survey and highlighted a preference to leave it alone/do nothing (60), improve parking safety and security (58), keep it natural (39), and more parking (33). The remaining suggestions highlighted a wide range of ideas, with items like restrooms (14), trash (17), dog bags/dog waste (19), and shade/trees (12) among the most cited. Several suggestions addressed trail improvements, including maps (10), signage (10), separate trails for hikers and bikers (12), and adding new trails (10). Less frequent mentions included amenities like adding a bridge at access Hagador Trail (9), water fountains (9), seating (8), mile markers (6), and safety features such as fire prevention clearing (4), safety signs (6).
Unique ideas, mentioned only once or twice, ranged from trail etiquette and level of difficulty signage to self-guided nature routes, vending machines, emergency boxes, bike parks, and a zip line.
Overall, the feedback was consistent in prioritizing preservation along with a few select amenities:
restrooms, water fountains, trail maps, and trail signage, trees, shade and seating, nearby parking, and improved security.
3.3 Outreach to User Groups
Staff participated in seven outreach activities at Skyline Drive and City events from July 18 through August 8. During these engagements, staff discussed the Skyline Area Plan and asked all respondents to include their comments in the online Skyline survey to capture all feedback in a single location.
During the outreach events, several residents expressed their desire for a bridge that would connect Skyline Drive to Hagador Trail. Currently, trail users step over a guard rail and cross this area on an improvised log bridge over the Tin Mine creek. There are two historical bridges that cross the drainage area on the eastern portion of the meadow. Many requested to keep these bridges and refurbish them to provide access to the eastern section of the property and keep a historic aesthetic feature for the area. There were also requests for the trail directly east of the meadow to be more accessible, and for circuit trails that residents could use to walk or run on.
Many respondents complained about the lack of parking and the break-ins on Foothill Pkwy.
Mountain bikers stated a tree had fallen on the southernmost trail along the south side of the 18 meadow, which makes access to this area more difficult. Several inquiries were also made about why the well-used access through Skyline Drive was blocked underneath the Foothill Pkwy overpass.
On September 16, 2024, staff met with several trails enthusiasts and former Trails Working Group members at the Skyline area to review the site and gather their input. Because the majority of the trails are double black diamond or extremely difficult, the group proposed adding a kid friendly “Blue Level” bike trail on the western side of the meadow. They also suggested installing seating at two scenic, accessible spots; one near the old pond area overlooking the meadow and the city, and another along the ridge trail offering mountain views.
Additional requests from the Trails Working Group include incorporating a circuit trail on the meadow which would fulfill the need for a close walking circuit, and maintaining existing trails by trimming vegetation, preserving the old bridges with refurbishments, and adding stairs to steep sections. Restrooms, an extra water fountain, and bike bells were recommended for convenience and safety. For signage, they suggested trail identification markers, reminders for quiet hiking, pack-in pack-out trash rules, single-track guidelines, caution signs for water availability, and mileage markers along Skyline Drive. Hosting mountain bike races and running events was also proposed to boost community engagement. Designating certain trails for “Hiking only” and “Biking only” were discouraged by the users as it would limit the number of trails each group could use and would be difficult to enforce.
4.0 Recommendations
The following recommendations for the Skyline area are derived from recommendations included in the Trails Master Plan, comments received from the Skyline area survey, outreach events, and comments made by the trail user groups. Recommendations are divided into three sections:
Improvements, Maintenance & Fire Prevention, and Policies & Procedures. 19 4.1 Improvements
