Roseville Digital Billboard Project Description
260 South Harding Boulevard, in the City of Roseville, Placer County. The site is adjacent to Interstate-80, south of Douglas Boulevard, at the southern terminus of Harding Boulevard (APN 014-183-029-000). The site is zoned for commercial use. The site has been disturbed, with little to no vegetation or landscaping.
Proposed Digital Billboard – Design & Height:
The digital billboard will be approximately 40’ to 55’ tall from grade to top of the sign cabinet, dependent on topography and orientation. The sign would be elevated approximately 45’ relative to the centerline of I-80. The sign would consist of two 672 square foot faces mounted in a “V” configuration oriented toward the eastbound and westbound lanes of I-80. The City sign would comply with applicable City design requirements.
LED lighting would be designed to make the message displays visible to passing motorists. Light sensors would be installed to measure ambient light levels and to adjust light intensity to respond to a change in ambient light conditions. Lighting levels on the digital billboard would not exceed 0.3 foot candles over ambient levels, as measured using a foot candle meter at a pre-set distance (250 feet for 14’x 48’ face size). The brightness of the LED display is subject to adjustment based on ambient conditions.
Construction of the billboard would be subject to the uniform building code, and a building permit would be required for construction activities. The City’s Public Works Department, Building Inspection Division would review the plans and specifications to ensure compliance with all applicable building code requirements.
Construction activities typically take a week to complete and include one drilling rig, one crane, and a small crew. The ultimate area of ground level disturbance is an approximately 10’ x 10’ area. The following would be completed to install the sign.
On the first day, the existing billboard would be dismantled and removed from the site. To construct the foundation, a drilling rig would drill a hole five feet (5’) in diameter and thirty-two feet (32’) deep. A trench plate would be placed over the hole to secure the site.
On the second day, the column (or base) for the sign is delivered to the site. The column is typically 42” in diameter. The column is lifted into place in the foundation hole by a crane, and is maintained in place by I-beams that are welded to the column. If completed in time concrete is also poured on the second day. After the concrete cures the I-beam welds are ground off and the I-beams removed. The upper structure components are delivered to the site and assembled on the ground. The upper structure into place atop the column by crane. Extension of electrical service to the site will be in place prior to construction activities.
Construction activities would take place between 7:00 a.m. and 7:00 p.m. Monday through Friday and between 8:00 a.m. and 8:00 p.m. Saturday and Sunday, in compliance with the City noise ordinance.
