Living on the rim of Buck Gully gives you rare canyon-to-coast views and a deep sense of privacy. It also means your landscape choices carry extra weight for safety, permitting, and neighborhood view protections. In this guide, you’ll learn how to design and maintain a Corona del Mar rim-lot landscape that preserves sightlines, reduces fire and erosion risk, and aligns with City rules. Let’s dive in.
Buck Gully context
Buck Gully Reserve is a coastal canyon and watershed next to Corona del Mar, with a popular multi-mile trail system and habitat programs managed with the City of Newport Beach and the Irvine Ranch Conservancy. It is open dawn to dusk and dogs are not allowed. Review the City’s overview and hours on the City of Newport Beach Buck Gully page and see the Buck Gully Reserve overview for trail details.
Why this matters for you: your property sits at a canyon edge where views, slope stability, drainage, wildfire exposure, and habitat sensitivity intersect. Thoughtful landscaping helps you enjoy the setting while meeting City expectations for safety and scenic protections.
Rules that shape your landscape
Before you plant or grade, understand the frameworks that apply along the rim.
- Bluff and Canyon overlays. Properties mapped in these areas follow special development standards for setbacks, encroachments, and walls. Confirm your parcel’s status in the City’s Bluff and Canyon overlay zoning.
- Permits and reports. Work near a bluff or canyon edge often requires a Coastal Development Permit and technical studies such as geotechnical, drainage, and landscape plans. Start with the City’s Coastal Development Permit checklist to scope submittals.
- Scenic-view controls and fences. Corona del Mar has rules to protect coastal views, including openness requirements for taller fences in front setbacks. Review the City’s scenic and visual protection policies before installing hedges, screens, or walls.
- Fire and defensible space. The Newport Beach Fire Department inspects Hazard Reduction Zones and provides defensible space guidance for homes near canyon vegetation. Learn the zone concept and maintenance expectations in the City’s defensible space guidelines.
Safety first: slopes, water, fire
Stability and drainage
Slope stability can be affected by irrigation seepage, poorly placed runoff, removal of deep-rooted plants, and unengineered terraces. City policy requires projects to avoid creating or worsening erosion or instability. Practical steps:
- Favor deep-rooted native shrubs and grasses to anchor soils.
- Keep spray irrigation off and away from canyon faces. Use drip with moisture sensors and set heads back from slope edges.
- Capture and disperse roof and hardscape runoff to vegetated areas or engineered detention. Avoid concentrating flow onto slopes.
- Involve licensed engineers early if you are considering retaining walls, terraces, or subdrains. Walls over certain heights require engineering and approvals.
Wildfire and defensible space
Buck Gully’s vegetation creates a Wildland Urban Interface context. Reduce risks with layered zones:
- 0 to 5 feet: keep it clean and noncombustible near the home. Use gravel, stone, or irrigated low plantings.
- 5 to 30 feet: choose low-fuel plants, break up continuous beds, and prune regularly to eliminate ladder fuels.
- 30 to 100 feet: thin, space, and remove dead material while respecting property lines and sensitive areas. See the City’s defensible space guidelines and fire-smart landscaping tips from UC ANR.
Views, privacy, neighbors
City policies protect public coastal views, so plan for mature plant height and spread. Keep lower planting near public edges and set taller screening farther back from the rim. Use open fencing styles where required to maintain sightlines.
Habitat-friendly choices
Avoid invasive species that can spread into the reserve, such as iceplant, pampas grass, fountain grass, and Algerian ivy. Use the invasive plant list for Southern California to steer clear of problem plants.
Plant palette for views and safety
Groundcovers and stabilizers
Choose species that knit soils without growing tall. Examples include California fescue, coastal buckwheats, and other native grasses and groundcovers well suited to coastal slopes.
Shrubs for controlled screening
Use coastal natives like coyote bush, California sagebrush, ceanothus, and toyon. Plan for mature size and keep shrubs trimmed to preserve view corridors.
Succulents for exposed spots
On rocky micro-sites, add low, site-appropriate succulents sparingly as accents. Ensure any Dudleya species are sourced ethically, as some are protected.
What to avoid
Skip aggressive or high-fuel species. In addition to invasive plants, avoid tall continuous hedges at the rim that can block public views or create ladder fuels.
Layout tactics that protect views
- Use low planting bands near the rim, generally under 3 to 4 feet, to keep sightlines open.
- Place taller elements back from the edge and within private areas of the yard.
- Prefer open fencing where the code calls for openness in front setbacks.
- Stagger plant groupings instead of continuous hedge lines to maintain view corridors.
Irrigation and maintenance on the rim
- Favor drip irrigation with separate valves for slope zones and moisture sensors to prevent overwatering.
- Program cycle-and-soak schedules to reduce runoff.
- Avoid permanent spray near canyon faces. Permanent irrigation is discouraged adjacent to dedicated open space.
- Schedule seasonal pruning, dead-fuel removal, and inspections to meet fire department timelines.
When to bring in engineers
If vegetation alone cannot address erosion or stability, engineered solutions like retaining walls, terraces, and subdrains may be appropriate. These improvements must be designed by licensed professionals and permitted. Soft-engineering tools like coir logs and erosion-control blankets can complement planting and are often preferred over hard armoring.
A simple plan to get started
- Confirm your overlays. Check whether your lot is in a Bluff or Canyon overlay or a Hazard Reduction Zone.
- Scope approvals. Review the City’s Coastal Development Permit checklist and ask Planning about required studies.
- Align with fire timelines. Note inspection schedules and defensible space requirements from Newport Beach Fire.
- Select plants and layout. Prioritize native, low-fuel species sized for views and safety. Avoid invasives.
- Build your team. Retain licensed geotechnical, civil, and landscape professionals as needed to design and permit work.

FAQs
Do Corona del Mar homeowners next to Buck Gully need special permits for slope landscaping?
- If your project involves grading, retaining walls, irrigation near the rim, or significant planting changes, expect Coastal Development Permit review and technical studies as outlined in the City’s Coastal Development Permit checklist.
Are tall hedges allowed to block public coastal views in Corona del Mar?
- Not typically. Scenic and visual protection policies limit structures and plantings that substantially obstruct public views, so plan for mature plant height and consult the City before installing tall screening near public edges.
How does Newport Beach define defensible space for Buck Gully rim homes?
- The City follows a zoned approach that keeps the first 0 to 5 feet ember-resistant, manages spacing and fuel in 5 to 30 feet, and thins out to 100 feet where applicable, aligning with state guidance.
Who maintains vegetation on the slope below my Buck Gully property?
- It depends on parcel boundaries. In many cases homeowners own vegetated slopes to the municipal streambed and must meet defensible-space obligations, while the City manages public portions. Verify with title and parcel maps and see local reporting for context.
Can I install a seawall near the mouth of Buck Gully?
- Seawalls and hard armoring are highly regulated and generally discouraged unless unavoidable. The City’s coastal policies and state review require rigorous justification and favor soft-engineering where feasible.
