Residential Site Plan Revision in Grass Valley, California

The challenge.

The project involved a proposed new single-family residence on a rural property in Nevada County, California. The existing site contained a gravel driveway, water-related features, septic facilities, a well, vegetation, and other conditions requiring coordination with the proposed development.

The site plan needed to be revised in response to supplied Building, Planning, and Fire Marshal review comments. Key documentation requirements included identifying the proposed residence and covered porch, organizing site access and parking, illustrating fire apparatus maneuvering space, and showing the relationship between proposed construction and existing property features.

The project also required attention to defensible-space considerations, septic and public water coordination, an existing well designated for abandonment, impervious-area calculations, and erosion-control measures.

The challenge was to organize these overlapping requirements into a clear and dimensioned drawing set that could support continued permit review.

Our approach.

We prepared a coordinated site plan revision using the available property information, proposed residence dimensions, and supplied review comments.

**Property and building placement:** The site drawing identified property boundaries, parcel dimensions, the proposed residence footprint, and the covered porch area.

**Driveway, parking, and access:** The drawing documented the existing gravel driveway, vehicle parking areas, and a designated fire apparatus turning and maneuvering area.

**Water and wastewater coordination:** Existing and proposed water-related features were identified, including public water service, the existing septic system and drainfield, and the existing well designated for abandonment.

**Wildfire defensible space:** The plan illustrated defensible-space and fuel-management considerations around the proposed residential development, including the designated noncombustible or ember-resistant area near the residence.

**Site coverage calculations:** Proposed building and porch areas were documented, along with the calculated impervious coverage for the property.

**Erosion-control documentation:** The site plan identified proposed silt-fence locations, supported by a separate isometric silt-fence detail showing fence fabric, posts, trenching, and backfill.

The resulting two-sheet package combined general site layout, access, utilities, fire-related site information, and erosion-control documentation in a coordinated presentation.

The outcome.

A revised two-sheet residential site plan drawing package was prepared for the proposed Grass Valley residence.

The drawings documented the planned building footprint, covered porch, site access and parking, fire apparatus maneuvering area, water and septic features, defensible-space provisions, and erosion-control measures.

The site plan also identified a proposed 1,182-square-foot residence and a 424-square-foot covered porch, giving a total documented building and porch area of 1,606 square feet. The corresponding impervious coverage was shown as approximately 1.43% of the property area.

This project demonstrates how coordinated site planning can address multiple technical and permitting considerations on a rural residential property.

The drawing package was prepared for client review and permit coordination. Final municipal approval and construction completion have not been independently verified.
