NG-1: Neighborhood General 1 - Subdivision Zoning District in Grass Valley
The NG-1: Neighborhood General 1 - Subdivision zoning district in the City of Grass Valley is a residential classification within the "Traditional Community Development Zones" that implements the Urban Low Density (ULD) General Plan designation. This district is characterized by a "walkable" scale that prioritizes pedestrian connectivity and the preservation of historic small-town character, strictly prohibiting "gated communities" or walled-off residential areas [Table 1-1, Section 17.88.040].
Purpose and General Character
The primary intent of the NG-1: Neighborhood General 1 - Subdivision zone is to manage residential growth in a way that protects the historical community identity of Grass Valley while ensuring development is of a human scale [Section 17.10.010].
Traditional Neighborhood Design
As a district governed by the Grass Valley traditional neighborhood subdivision requirements, the NG-1: Neighborhood General 1 - Subdivision zone emphasizes the following characteristics:
- Interconnectivity: Streets must be interconnected with adjacent developments to provide multiple routes for pedestrians and vehicles [Section 17.88.040].
- Walkable Scale: Developments are designed to place homes within one-quarter mile of a neighborhood park, public facility, or shopping opportunity [Section 17.88.040].
- Block Lengths: Block faces between intersecting streets must be as short as possible, generally not exceeding 400 feet [Section 17.88.040].
- Open Access: The zone prohibits the creation of disconnected or "walled-off" areas. New residential developments must provide general public pedestrian and vehicle access to all streets and sidewalks [Section 17.88.030].
Land Use and Development Standards
All development in the NG-1: Neighborhood General 1 - Subdivision zone must comply with the standards for Traditional Community Development Zones, which utilize "build-to lines" rather than standard setbacks to shape the public space of the street [Section 17.21.020].
