35 New Townhomes Under Construction in Huntington Beach: Coastlands at Holly Triangle
Bonanni Development's Coastlands community is one of the few new for-sale ownership projects currently under construction in Huntington Beach. The 35-unit townhome development sits at the corner of Holly Lane and Main Street in the Holly-Seacliff neighborhood, a well-established residential area roughly a mile from the beach. Three-story floor plans range from 2 to 3 bedrooms with up to 2,040 square feet, two-car garages, and rooftop decks on select plans. All 35 homes are solar-powered. Prices start in the low $1 millions. The project is on track to deliver in mid-2026.
The site itself has a story. This is not a straightforward infill lot. The project required capping four abandoned oil wells, routing around a crude oil pipeline and easement that runs through the center of the property, and rezoning the land from commercial to residential. It took a General Plan Amendment, a Zone Text Amendment within the Holly-Seacliff Specific Plan, a Conditional Use Permit, and a new environmental addendum to get to the point where construction could begin. The fact that it is now vertical and nearing delivery reflects a developer with significant experience navigating complicated infill sites in Huntington Beach.
The Site: A Constrained Triangular Lot with an Oil Field Past
The Coastlands site occupies 2.11 gross acres (1.80 net acres) at 19070 Holly Lane in Huntington Beach's 92648 zip code. The property is triangular in shape, defined by the intersection of Holly Lane and Main Street, which gave the project its original name: Holly Triangle. The irregular geometry of a triangular lot creates real constraints for a builder. There is less usable square footage than a rectangular parcel of equal area, setbacks eat into the corners differently, and the site's prominent intersection placement makes building orientation and streetscape design more complex.
The lot was previously occupied by a one-story commercial building and a vehicle storage yard, both underutilized uses in a neighborhood that has been predominantly residential for decades. Beneath the surface, the site contained four abandoned oil wells and an active crude oil pipeline easement running through the center. The pipeline easement is a physical constraint that shaped how the seven buildings are arranged on the site, since development cannot occur within the easement corridor. Bonanni worked through a Phase I Environmental Site Assessment and a geotechnical investigation as part of the entitlement process to document site conditions and establish the mitigation measures required to build safely here.
The Holly-Seacliff neighborhood surrounds the site. The broader Holly-Seacliff area was master-planned in the late 1980s and early 1990s and is one of Huntington Beach's more cohesive planned residential communities, with established parks, trail connections, and a primarily residential character. Main Street is one of the neighborhood's primary north-south streets and connects the area to Downtown HB and PCH to the south. The beach is approximately one mile away.
Floor Plans, Features, and Pricing
Coastlands consists of 35 three-story attached townhomes organized into seven buildings. Three floor plan types are offered, ranging from 2 to 3 bedrooms with 2.5 baths and up to 2,040 square feet of living space. Each home includes a dedicated two-bay garage at the ground level and open-plan living areas on the upper floors. Select plans include rooftop decks, and others feature private decks off the great room. All 35 homes come with solar panels included.

Five of the 35 homes are set aside as affordable to moderate-income households per city policy, which amounts to 15 percent of the total, a higher affordable percentage than the city's standard 10 percent requirement. The remaining 30 homes are market-rate for-sale ownership units.
At prices starting in the low $1 millions for a new three-story solar townhome with a two-car garage in a walkable Huntington Beach neighborhood, Coastlands sits at an attractive entry point relative to comparable new construction along the coast. Resale townhomes in the Holly-Seacliff area have been trading at similar or higher price points for smaller and older product, which underscores the value proposition for buyers who can access new construction here.
The Approval Path: Zone Change, Oil Wells, and a Pipeline Easement
Getting Coastlands approved required more than a standard building permit. The site's underlying zoning under the Holly-Seacliff Specific Plan was Commercial, meaning it was designated for retail and service uses, not homes. To develop residential here, Bonanni needed to amend both the city's General Plan and the Specific Plan itself. The General Plan designation changed from Commercial Neighborhood with Specific Plan Overlay (CN-sp) to Residential Medium Density with Specific Plan Overlay (RM-sp). The Specific Plan zone text was amended from Commercial (C) to Residential Medium Density (RM). Twelve existing parcels were consolidated into a single 1.80 net acre lot through Tentative Tract Map No. 19118.
The environmental process required an addendum to the Holly-Seacliff Specific Plan EIR, a document originally certified in 1989. EPD Solutions prepared the addendum on behalf of the City of Huntington Beach and reviewed technical studies covering air quality and greenhouse gas emissions, geotechnical conditions, noise, a Phase I Environmental Site Assessment, hydrology, and water quality. The four abandoned oil wells on the site were capped as part of site preparation, and the pipeline easement running through the property was accounted for in the site plan layout.
The project was assigned to City Planner Jason Kelley in the Community Development Department. As of May 2025, the city's project tracking page lists the status as Under Construction, meaning all entitlements have been granted and construction has begun.
About the Developer: Bonanni Development
Bonanni Development is a Huntington Beach-based homebuilder with more than 30 years of experience building in Orange County. The company specializes in smaller-scale infill projects in established coastal communities, the kind of constrained sites that larger national builders typically pass on. The Holly Triangle site, with its triangular shape, abandoned oil wells, and pipeline easement, is exactly the type of project Bonanni is suited for. Their familiarity with Huntington Beach's entitlement process, planning staff, and specific plan framework is an asset on a project like this where local knowledge matters.
Bonanni is handling sales and marketing for Coastlands through Strategic Sales and Marketing, a firm that specializes in new home community launches. Interested buyers can register for updates through the sales program directly.
What Buyers Should Know
Coastlands is one of the very few new for-sale communities under construction in Huntington Beach right now. New ownership product in HB is scarce at any price point, and the combination of beach proximity, solar inclusion, two-car garages, rooftop decks, and pricing in the low $1 millions puts this project in a competitive position relative to existing inventory. With a mid-2026 delivery target and construction already underway, this is not a multi-year wait like some of the other projects in the HB pipeline. Buyers who register now are the first to know when units are released for sale.
The five moderate-income affordable units will be sold through a separate process governed by the city's affordable housing program, with income restrictions and resale controls attached. The 30 market-rate homes are available to qualified buyers without income restrictions.
We track Coastlands and every other new development across Huntington Beach and Orange County. If you want to get on the interest list, understand how the sales process works, or compare this community to other options, reach out directly.
