I sympathize with Mr. Morrison's requesting definition clarity (Board Agenda letter 9/25/18) on how a "remote" winery is defined.

In Napa County, we do not consider remote wineries and vineyards which are located on the valley floor but ones which are exclusively located in the hillsides. We therefore need to define the hillside location factors which would merit special considerations for new vineyards and wineries or expansion of existing ones.

They include:


1) Loss of woodlands.
A partial list includes:
a) Aesthetic degradation of a scarred landscape (an important asset to the Napa valley experience).
b) Negative impacts on water quality and stream siltation, municipal watersheds etc.
c) Negative impacts on animal habitat.


1) Increased traffic.
a) Oversized vehicles for agricultural and wine making operations.
b) Large limousine and personal vehicles for visitors and events.

2) Increased fire danger by the increase of workers and visitors in fire prone areas.
3) Difficulty in navigating the generally narrow roads on opposing traffic situations.
4) Inadequate escape and emergency vehicle access routes.


It is my contention that at its core, the term "remote" implies "hillside development" considerations. As such, the term "remote" does not reflect the fundamental issues which have initiated this inquiry.

Conceivably, one could define "remoteness" in quantifying acceptable negative impacts on the hillsides' environmental factors, in which case, "remoteness" would not necessarily be linked to the distance from some defined point.

While important, this paper will not attempt to evaluate "remoteness" within the environmental relevance / impacts framework.

Rather, it will concentrate in examining it in relation to the introduction of commercial / agricultural vineyard and winery operations in the hillsides. Specifically, it will examne compliance with existing minimum established County road standards and provide related recommendations.

NAPA COUNTY ROAD & STREET STANDARDS (Revised September 26, 2017)

SECTION 14 / Street and Road Classifications

Major Roads
The pertinent road classifications serving vineyards and wineries are either (a) Arterial (Collectors to Highways) or (b) Collector (1,000 to 5,000 vehicles per day). These roads are through-roads, not Dead- End-Roads.

Minor Roads
These are defined as serving "up to 1,000 vehicles per day". They may have a Cul-de-Sac (e) but then they may have a "maximum traffic volume of up to 250 vehicles per day". "Cul-de-Sac situations with lengths greater than 1,000 feet shall be provided with turnaround areas at 1,000 foot intervals and emergency access unless it is not considered feasible by the County Engineer".

It is important to note that the requirement is for turnarounds, not turnouts.
Furthermore, the criterion of feasibility is not defined beyond the generally accepted topographic and economic considerations and ignores public safety, health and welfare.

Other Roads
(i) Agricultural Special Purpose Roads
"Serves agricultural related single use facilities and light traffic facilities which generate up to 100 vehicle trips per day. This road is not applicable to any winery access. Applies to lightly travelled, low speed roads connecting two activity areas with no significant side traffic. Turnouts must be inter-visible".
Unless agricultural activities using such roads do not comply with this specification, they must be accessed by Major or Minor roads.

SECTION 15 / Design Criteria

Roadway Width:

Dead-End-Roads Specifications:

The Napa valley hillsides have a plethora of dead-end roads, many exceeding 3 miles. Soda Canyon Road and Diamond Mountain Road are just a few examples, well above the maximum allowable 5,260 feet.

I am not aware of any of the county's hillside roads being in compliance with ANY and ALL of the above requirements or exceptions.


Unless there are exceptions I am not aware of, all of the county's hillside roads are out of compliance with the County's Road Standards.

The County Engineer and Fire Marshal have in the past exercised their discretionary power in approving them in the interests of development while increasing the risk of residents', workers' and visitors' inadequate escape routes and the concurrent access to emergency vehicles.

Given the increased danger of fires as we have experienced and will continue to do so in the foreseeable future and in order for the County to avoid being knowingly complicit in case of catastrophic loss of life of property as well as in the interest of public health and safety I recommend that:

Finally, since the issue of remoteness does not reflect actual considerations of remoteness but rather environmental and access safety ones, I recommend that a designation reflecting its actual purposes be adopted.
