... and in his response to that letter, Professional Engineer Gerald R. Giorgi expressly alerted the landowner that he should "count on being sued" should another flood occur and neighbors be damaged, for "whatever reason" ...
Agenda Item #6.3.
It is unfortunate the General Plan guidelines the professional engineers recommendations were ignored, but when Measure A was passed in 1998, residents of Vineyard Valley, fearing the future flood warned by engineer Giorgi, fought assertively to have their flood protection upgraded to avoid the next damaging flood. Vineyard Valley residents were comforted by the inclusion of this Measure A set-aside to fund flood protection for St. Helena ...
In December 2008, residents sought to preserve the floodplain by suggesting this upgrade to Agenda Item #6.3.
the extant cinder block wall erected after Vineyard Valley's flood in 1986 to flood standard, along Vineyard Valley's north property line ...
Unfortunately the residents were ignored and the levee alignment now cordons off a major component of the natural floodplain, with obvious flood risk increases by obstructing the floodplain.
The residents proposed the remaining floodplain be preserved as a public riverbank park, but advocates of the ill-designed levee across the floodplain won the argument and Vineyard Valley flood protection was approved across the very floodplain that had flooded Vineyard Valley so badly in 1986 and 1995.
When Vineyard Valley residents asked why the levee had to obstruct the floodplain instead of upgrading the cinder block wall along their north property line, and they were told upgraded floodwall around Vineyard Valley and Hunter's Grove "would not work." As an engineer myself, I can only conclude the levee alignment was built across the floodplain to protect developer Hunter's property at public expense, and the sacrifice of a large portion of the historic floodplain.
UC Davis Engineering Professor Nicholas Pinter wrote after completing a site inspection that he found our levee a "field of dreams levee" as he wrote in this report. City management may want to inquire of Professor Pinter as to his opinion of the wisdom of permitting housing development behind the levee.
I personally trust Professor Pinter significantly than I trust the engineers who dangerously aligned our levee right through the middle of our floodplain.
Thank you for your consideration.

Subject: Hunter Project-ERI Scoping Input
Date: Thursday, April 12, 2018 4:11:07 PM
To the City Clerk, St. Helena, et al,
This note is a submission in response to the request for input on the Hunter Property Development EIR scoping exercise.
As you may be aware my home is located somewhat at ground zero of this proposed development and the results of the EIR impacts me very directly and those of my immediate neighbors and the greater St. Helena community dramatically. The EIR, which seems to be evolving with considerable thought, does seem to be predicated on some larger issues that are being relegated to past decisions that do not appear to be as well thought out and that is concerning to me, substantially.
I am relatively new to the community and while attempting to discover what has been a very long process in developing this property there are more questions raised than answered. I would consider myself pro-development but with the caveat that any development is very well thought out, vetted intensely, and evolved with the best practices for the whole community/City in its considerations and approvals. I am pro-development, and not a developer. But I know instinctively when something is not of the potential standard that the community needs and deserves. The very few illustrations of this development that I have seen are of the poorest creative quality that I could imagine and certainly do not seem to fit any, even minimal, urban plan for our City although I have made some efforts to discover what that may actually entail. As I stated in one of the public meetings I am somewhat baffled by the rush to move a poorly defined project forward without much more discovery.
These comments are somewhat outside the bounds of the Scoping Request but the Discovery process is directly related to that Request. I have heard of my neighbors concerns, and they are ground zero concerns, and whole community concerns of mine as well in relation to traffic, water, resources, noise, costs, liability, and impact on every aspect of the future of this City that I am quickly coming to value and appreciate deeply.
Somewhat disconcerting is the revelation that a previous EIR contained information which is to be transported into the new EIR without review. I am particularly concerned with the whole process of developing the levee and its viability particularly relative to the news of so many levees and similar structures in Houston, New Orleans and elsewhere failing when they were supposed to be certified ‘100 year flood’ capable. If this levee fails who is responsible for the destruction that will devastate so many in this community? Who pays for those types of catastrophes? I would ask that this issue not be swept under the proverbial rug and be added, Agenda Item #6.3.
in-depth, to the scope of the EIR work.
My thanks for your work and the commitment from every one of our councilors, City Staff and Executive and Counsel, the Mayor and all of those tasked with this EIR work and they all contribute to our future which is bright indeed.

LESA Worksheet (cont.) Part 3. Surrounding Agricultural Land Use Score:
NOTES
(1) Calculate the project’s Zone of Influence (ZOI) as follows:
(a) a rectangle is drawn around the project such that the rectangle is the smallest that can completely encompass the project area. (b) a second rectangle is then drawn which extends one quarter mile on all sides beyond the first rectangle.
(c) The ZOI includes all parcels that are contained within or are intersected by the second rectangle, less the area of the project itself.
(2) Sum the area of all parcels to determine the total acreage of the ZOI. (3) Determine which parcels are in agricultural use and sum the areas of these parcels (4) Divide the area in agriculture found in step (3) by the total area of the ZOI found in step (2) to determine the percent of the ZOI that is in agricultural use. (5) Determine the Surrounding Agricultural Land Score utilizing the Surrounding Agricultural Land Scoring Table below.

NOTES
The Protected Resource Lands scoring relies upon the same Zone of Influence information gathered in Part 3, and figures are entered in Site Assessment Worksheet 3, which combines the surrounding agricultural and protected lands calculations. (1) Use the total area of the ZOI calculated in Part 3. for the Surrounding Agricultural Land Use score. (2) Sum the area of those parcels within the ZOI that are protected resource lands, as defined in the California Agricultural LESA Guidelines. (3) Divide the area that is determined to be protected in Step (2) by the total acreage of the ZOI to determine the percentage of the surrounding area that is under resource protection. (4) Determine the Surrounding Protected Resource Land Score utilizing the Surrounding Protected Resource Land Scoring Table below.
