Raymus Homes is seeking to build 68 more homes in east Manteca.

The project known as 4-C Ranch is proposed north of Louise Avenue and east of the Diamond Oaks neighborhood KB Homes built in the mid-1990s.

The neighborhood will require the extension of Vasconcellos Avenue north of Louise Avenue.

Cork Oak Lane and Black Pine Way — two stubbed streets in the Diamond Oaks neighborhood — will be extended to the east.

The project will require the 19.68 acres to be annexed to the city.

It is within the general plan’s sphere of influence. As such, the land has already been identified as a logical annexation to the city.

Once annexed, it will bring  the City of Manteca boundary north of Louise Avenue to within a quarter of a mile of Austin Road.

Manteca’s city limits already border roughly 50 percent of the west side of Austin Road between Louise Avenue and East Highway 120 (Yosemite Avenue).

The city already borders all of Austin Road’s west side between East Highway 120 and the Highway 99 overcrossing.

Development in Wast Manteca has been relatively low-key in recent years.

That’s because much of the area contagious to existing development is in smaller parcels that are suitable for a subdivision are between 5 and 20 acres,

The area, just like Woodward Avenue before development started south of the 120 Bypass, has numerous one acre and even smaller rural estate style parcels lining much of Lathrop Road, Southland Road, Northland Road, Austin Road, and Castle Road.

They are between areas that are now developed and larger tracts of land more conducive to subdivisions of 150 homes or larger.

It means development on a large scale is not expected to happen in the short term horizon of five years or so.

That said, northeast area — in addition to southeast Manteca — are the areas that factor in heavily to Manteca potentially reaching 211,000 residents based on the city’s current general plan .

The epicenter of home building will likely be in southwest and mid-south Manteca for the next 5 to 10 years.
