The last piece of the puzzle is finally falling into place for the Rancho del Oro Master Plan in Oceanside. Grading started earlier this year to prepare the site at the northwest corner of College Boulevard and Old Grove Road for the 317-unit, gated community of Pacific Ridge.

High levels of interest are already being generated and homes are expected to sell swiftly when they go on sale next summer because of the community’s prime location, thoughtful design and sought after amenities.

“This is a beautiful project in a prestigious hilltop location ideally located with access to three main freeways for commuting to anywhere in San Diego County,” said Michael Sabourin, president and COO of Cornerstone Communities.

The project was initially envisioned as an apartment complex, but things shifted course last year, said Paul Lucatuorto, a pricipal at Presidio Residential Capital – Cornerstone’s partner in the project. The market for single-family homes and townhomes has grown and they would be more compatible than apartments with the surrounding community, Lucatuorto said.

The revisions will require Planning Commission approval, said Jeff Hunt, Oceanside’s city planner. Cornerstone has started grading the property under a permit approved for the apartment project, anticipating that the new project will be also be approved, Hunt said.

Construction on Pacific Ridge is expected to begin in January 2016.

Pacific Ridge is within Oceanside’s 1,950-acre Rancho Del Oro master planned community, made up of several subdivisions or “villages.” Many of those villages are located near College Boulevard north of Oceanside Boulevard and others south of Mesa Drive between College and El Camino Real. Each village has its own master plan outlining what can be built within.

The plan for Pacific Ridge has three distinct communities within the development:

Lucero will have 125 three-and-a-half to four-bedroom luxury townhomes ranging from 1,570 to 1,825 square feet.

Brisas will have 120 two-story three- to four-bedroom and up to three-and-a-half-bath tri-plex townhomes ranging from 1,480 to 1,812 square feet.

Altura will have 72 upscale three-to four-bedroom, two-and-a-half-bath two-story single-family detached homes ranging from 1,770 to 2,030 square feet.

The commuity will also have a heated lap pool, a spa, a dog park, playgrounds, an outdoor fitness space and a community walking path.

Councilman Chuck Lowery said the project appears to be well thought out. The city has about 3,000 homes, including this project, in the development cue, he said.

“This seems like a pretty upscale project,” Lowery said. He said Oceanside now has roughly 3,000 new homes in its development pipeline.
