Where Is Newberg Growing?

Newberg counted 25,138 people in the 2020 Census, and the Census Bureau estimated 26,896 by July 2025. More than a third of the town's homes went up in 2000 or later, the American Community Survey shows.

New subdivisions keep coming on the north and east sides of town. The city's planning division lists subdivisions off Mountainview Drive and Springbrook Road, and another on OR 99W near Rex Hill. A new subdivision starts as raw ground that needs its streets and utilities in before the builders can dig.

Newberg's Public Works Design and Construction Standards cover public streets, storm lines, sanitary sewer and water mains. The city keeps its storm drain pipes separate from the sanitary sewer. On a subdivision, we follow the engineer's plans and put every utility in before the street goes over it.

What Is the Ground Like Under Newberg?

Much of Newberg's flat ground formed in lake silt left by the Missoula Floods. The NRCS rates Aloha silt loam somewhat poorly drained. Woodburn silt loam drains better, but its water table rises highest from December to March.

The ground gets wetter along the creeks. Wapato silty clay loam on the floodplains is poorly drained and can flood between December and April. Chehalem Creek and Hess Creek both cross Newberg, and the Willamette River runs along the south edge of town.

NOAA's weather station near Rex, just east of town, averages about 44 inches of rain a year. June through August brings only about 2.5 inches of it. We plan heavy grading and earthwork for the dry months. On wet lots, storm drainage and French drains carry the winter water away from the pads.

Site Work Permits in Newberg and Yamhill County

Newberg's engineering department handles permits for public improvements, erosion control, demolition and franchise utilities. Disturbing more than 500 square feet of soil in the city calls for its erosion and sedimentation control permit. At an acre or more, Oregon DEQ's 1200-C construction stormwater permit applies too.

Land use applications, new subdivisions among them, go to the city's Planning Division in Community Development. The Building Division handles plan review and inspections for construction. It also does that work for Dayton, Dundee and Lafayette under contract. Outside the city limits, Yamhill County Planning and Development in McMinnville handles land use and building permits.

In a subdivision, a lot under an acre can still need 1200-C coverage as part of the larger plan. For permit questions on a specific lot, the city's engineering office has the answers, and we point you there.

Commercial Sites and Farm Ground Around Newberg

OR 99W runs east and west through Newberg, and commercial lots sit along the highway. Our commercial site work covers clearing, the building pad, utilities and the parking lot base.

Past the city limits, the Chehalem Valley holds farm ground and rural home sites on acreage. On the hills at the north and east edges of town, the NRCS maps well-drained Saum and Laurelwood silt loams. For farms and nurseries, we grade fields and growing areas and build equipment yards. On acreage, we prepare a full home site, with the clearing, the building pad, the utilities and the long drive.
