SUBJECT: CD2023-0017 (PUB2023-0021) - STAGECOACH COMMUNITY GARDEN (CIP 4611) The City Planner has completed a review of your application for a Consistency Determination (APNs: 223- 060-60-00, 223-060-51-00), which is a modification to Conditional Use Permit (CUP), CUP-265, approved by the Planning Commission on June 12, 1985. CUP-265 was approved for the development of Stagecoach Community Park, a 29-acre community park located at 3420 Camino De Los Caches, Carlsbad, CA 92009.

The request is to construct and operate an outdoor 6,700-square-foot community garden at the southeast section of the park near Camino De Los Caches and Maverick Way.

After careful consideration of the request, the City Planner has determined that the request meets all of the findings below and APPROVES this request. The proposed modifications include:
• Install 35 new raised planting beds with irrigation;
• Install a new 12-foot-tall shade structure, a premanufactured tool storage area, one picnic table, two benches, waste containers, compost bins, one drinking fountain, and an information kiosk;
• Remove existing concrete and install 438 square feet of new concrete pavers; • Remove the existing chain-link fence and install 312 linear feet of new fencing with a pedestrian gate and a vehicular double gate;
• Install a new 147-linear-foot retaining wall, that ranges from one to six feet in height, on the southeast section of Stagecoach Community Park
Note that this approval does not include an analysis of the "future police substation," which is shown on the updated layout plan. If a substation is proposed, it will be subject to separate review and approval.

In order for a Discretionary Permit Consistency Determination to be approved, all of the following findings must be made:
1) No project condition, feature, facility or amenity is changed or deleted that had been considered essential to the project's design, quality, safety or function in that the proposed improvements transform an unprogrammed part of the park into a usable space for residents and would not interfere with the current operation and design of the park. 2) The request represents an upgrade in overall design features and or materials and improves upon the project's compatibility with the surrounding neighborhood in that the proposed community garden will upgrade the area and integrate with the surrounding neighborhood, offering a new communal space without impacting the park's existing recreational uses. The community garden was designed to maximize space and access for gardeners, incorporating input from community members and the Carlsbad Community Gardens Collaborative, the city's April 23, 2024

administrative partner for community gardens. Hours of operation for the garden would be limited to 8 a.m. to 10 p.m., the same restriction in place already for the park and would adhere to lighting and noise restrictions consistent with CUP-265. There are no plans to add new lighting; instead, the project will utilize two existing light poles that are within the garden area.

The added accessories, such as the shade structure, picnic tables, and informational kiosks, will match the colors and materials of the existing outdoor furniture throughout the park. The retaining wall will be six feet tall, that ranges from one to six feet in height, and will be a split face CMU with a wheat color finish. The improvements, including the retaining wall, will be screened from public view by the existing site landscaping along Camino De Los Coches. 3) The proposed revision does not change the density or boundary of the subject property in that the proposed community garden is not a change in density and is within the existing developed footprint of the Stagecoach Community Park. When the park was approved, it was required to have 216 parking spaces according to the Environmental Impact Report (EIR} certified on June 12, 1985 (EIR 84-05}. To date, the Parks and Recreation staff have identified 240 parking spaces available on the premises. The proposal to transform a vacant and underutilized area into a community garden will not result in the removal of any parking spaces and is not expected to exceed the existing parking capacity. Moreover, based on the expertise of the Parks and Recreation Department staff, who manage the Stagecoach Community Park along with other community gardens across the city, the introduction of a new community garden will not significantly increase parking demand. Observations by the Parks staff indicate that on weekdays community gardens attract 1-3 vehicles from community members and on weekends the number ranges from 2-5 vehicles. This analysis of parking is provided to articulate that the community garden will not impact off-street parking for the current operation of the park. It is not establishing a requirement for parking spaces for current or future community garden projects.

3Review of other communities as completed by Parks and Recreation Department staff and survey of neighboring cities including, the County of San Diego, City of Encinitas, and the City of Oceanside, suggests the parking required for a community garden be 1 space per 15 garden beds. If assumed that the community garden would require a reduction of 3 parking spaces, leaving a surplus of 21 parking spaces onsite.

4Per Carlsbad Municipal Code (CMC} section 21.44.030, where the parking requirements for a use are not specifically defined herein, the parking requirements for such use shall be determined by the city planner.
4) The proposed revision does not involve the addition of a new land use not shown on the original permit in that a community garden is consistent with the Open Space land use of the originally permitted park and would maintain consistency with existing park features. 5) The proposed revision does not rearrange the major land uses within the development in that the community garden is being proposed in an unprogrammed area of the original park site plan and would increase the usable space of the park by 0.05%. These improvements would not rearrange any of the existing park uses.
6} The proposed revision does not create changes of greater than ten percent provided that compliance will be maintained with the applicable development standards of the Carlsbad Municipal Code in that the proposed area of improvement is 6,700 square feet in aggregate, which represents 0.05% of the total park area of 29 acres and would be subject to park rules regarding hours and lighting. The In addition, as demonstrated in Finding 3 and the associated analysis, the community garden would not create a parking demand that exceeds existing capacity. The proposed changes would not conflict with any mitigation measures adopted as part of the park's EIR (EIRB4-05}.
7} The proposed change will not result in any significant environmental impact, and/or require additional mitigation in that the proposed community garden would occur in an already disturbed area of the Stagecoach Community Park adhering to the park's current regulations in alignment with EIR84-05. The garden will operate from 8 a.m. to 10 p.m. consistent with the park hours. There are no plans to add new lighting; instead, the project will utilize two existing light poles that are within the garden area . Gardening, by its nature, is not expected to produce additional noise beyond what has been previously approved by EIR84-05. The new retaining wall is being installed where there is currently ornamental landscaping and no sensitive habitat or cultural resources according to E/R84-0S. The project will implement general Best Management Practices {BMPs) to the extent practical, including defining disturbance boundaries, ensuring equipment is well-maintained, adhering to water quality BMPs, reducing chemical usage near sensitive areas, establishing protocols to minimize spill risks and to control sediment. The project will also comply with all stormwater requirements. Furthermore, as demonstrated in Finding 3, the new community garden does not create a parking demand that exceeds existing capacity.

With three community gardens already established across the city, the introduction of a new community garden in the southeast quadrant will enhance access for residents in this area. This addition is anticipated to reduce the need for daily travel among community members seeking garden spaces, thereby potentially decreasing the number of trips made by individuals within this community. The proposed change would not conflict with any other mitigation measures adopted as part of the park's EIR. Therefore, the project would not result in any significant environmental impacts or require additional mitigation measures. 8) The proposed change would not result in any health, safety or welfare impacts in that the original 1985 project approval, based on a review of related meeting minutes (Parks and Recreation Commission, Planning Commission, and City Council), did not identify major issues or April 23, 2024

controversies with the park, including on-site parking or the project's environmental review document.
9) There were not any major issues or controversies associated with the original project, which would be exacerbated with the proposed change in that the proposed community garden is in compliance with all conditions stipulated in CUP-265. The addition of a community garden meets the local community's needs, as identified in the Parks and Recreation Department's most recent needs assessment and comprehensive action plan. This initiative is prioritized among the plan's short-term action items. Furthermore, the establishment of the Stagecoach Community Garden will expand the city's community garden inventory to four. The existing gardens in this inventory include the Harold E. Smerdu Community Garden, the Pine Avenue Park Community Garden, and the Calavera Schoolhouse Community Garden at Calavera Hills Community Park. 10} The proposed change would not be readily discernable to the decision makers as being substantially different from the project as originally approved in that the project will improve the aesthetics of the site and appear as a continuation of the park.

Therefore, the City Planner has determined that the application qualifies for a consistency determination with the approved permit and approves the changes to the project based on Planning Division Administrative Policy No. 35.

Please submit two (2) blueline copies (11" X 17"} of all applicable exhibits for the project file of the amended site plan. The copies must be submitted, stamped "Consistency Determination," and signed by the City Planner prior to issuance of any grading or building permits for the project. The Consistency Determination Title Block stamp, and other Title Block stamps, can be downloaded from the City's website at https://www.carlsbadca.gov/departments/community-development/permits-applications­ forms/planning-applications-forms . The Title Block (stamp) is located at the bottom of the page.

NOTICE
This decision may be appealed by you or any other member of the public to the Planning Commission within ten days of the date of this letter. Appeals must be submitted in writing to the Planning Division at 1635 Faraday Avenue in Carlsbad, along with a payment of $900.00. The filing of such appeal within such time limit shall stay the effective date of the order of the City Planner until such time as a final decision on the appeal is reached.
