Hunter EIR Scoping Comments 4/12/18
Please find listed below areas that should be included in the scope of the new EIR. In addition, I have attached comments from a CEQA Attorney and my own comments prepared in response to the original DEIR. Also attached is an informational report prepared by the EPA that reviews how to protect water quality from Urban Runoff. These attachments detail many of the shortcomings of the original DEIR and I would like them included for consideration for the scoping of the new EIR.
Design, Implementation and Administration of the Affordable Units It will be very difficult to conduct a thorough EIR that subscribes to CEQA standards until the design, implementation, and administration of the affordable housing components are fully understood.
How and who is going to build them? Will they have to built before the market rate houses? How large will they be and how many occupants will they have. How many bedrooms, bathrooms, and parking spaces will there be? Are they going to be rentals or owner occupied? Will the multi-family units need zoning variances or conditional permits? Will the 10 lots with Granny units be deed restricted or under the control of the owner? What mechanisms are in place to ensure that the 10 granny units are indeed made available as affordable and when will they be built. If the project qualifies for a density bonus by right, should the EIR anticipate this and factor in the potential impact of additional units? All of this should be explained and understood BEFORE the EIR is started so that there are no surprises that could derail this second attempt at completing an EIR for this project. It is one thing to draw boxes on a sub-division map and designate them as affordable for development concessions. It is quite another to adequately explain how this will all work within the parameters of existing regulations and requirements. And, without this information, preparing an informed EIR will be incredibly difficult.
Design and Implementation of a controlled intersection at the Pope Street Bridge and Silverado Trail
Well after the completion of the last DEIR, the applicant claimed they had new information and that they would submit a design and pay for this intersection (along with approval from the County) to mitigate traffic impacts. Will information on how this will be accomplished (or is even practical) be provided BEFORE the start of the new EIR?
Plans for mitigating loss of State Designated Prime Agricultural Land Well after the completion of the last DEIR, the applicant claimed that they had new information for a plan for offsetting the loss of Prime Agricultural Land. Will this information be provided BEFORE the start of the new EIR?
Impacts of Traffic Through Neighborhoods
Agenda Item #5.5.
Beyond traffic count studies, will the new EIR take into account traffic that will utilize the Adams and Starr extensions to circumvent traffic delays on the Silverado Trail and Highway 29. The advent of apps like Waze and Google Maps will re-direct increasing amounts of traffic through neighborhoods.
Residents of Hunts Grove will now have to cross a busy intersection upon exiting their development.
This is a particular concern for the safety of children and pedestrians who now do not face crossing a street in order to walk to/from school or shopping.
Loss of open space and safe access to the Napa River Walk for pedestrians and dog walkers Once Starr is extended to meet Adams, residents and visitors who currently use the undeveloped city owned lot to access the River walk will be faced with sharing their walk with traffic and parked cars to reach the walk. This will be a significant danger to children and dog walkers.

and snowmelt remains above the
surface, where it runs off rapidly in
unnaturally large amounts.
Storm sewer systems concentrate
runoff into smooth, straight
conduits. This runoff gathers speed
and erosional power as it travels
underground. When this runoff
leaves the storm drains and empties
into a stream, its excessive volume
and power blast out streambanks,
damaging streamside vegetation and
wiping out aquatic habitat. These
increased storm flows carry sediment
loads from construction sites and
other denuded surfaces and eroded
streambanks. They often carry
higher water temperatures from
streets, roof tops, and parking lots,
which are harmful to the health and
reproduction of aquatic life.
from
Did you know that because of impervious surfaces like pavement and rooftops, a typical city block generates more than 5 times more runoff than a woodland area of the same size? The most recent National Water Quality Inventory reports that runoff from urbanized areas is the leading source of water quality impairments to surveyed estuaries and the third-largest source of impairments to surveyed lakes.
I
n urban and suburban areas, much
of the land surface is covered
by buildings and pavement, which
do not allow rain and snowmelt
to soak into the ground. Instead,
most developed areas rely on storm
drains to carry large amounts of
runoff from roofs and paved areas to
nearby waterways. The stormwater
runoff carries pollutants such as oil,
dirt, chemicals, and lawn fertilizers
directly to streams and rivers, where
they seriously harm water quality.
To protect surface water quality and
groundwater resources, development
should be designed and built to
minimize increases in runoff.
How Urbanized Areas
Affect Water Quality
Increased Runoff
The porous and varied terrain of
natural landscapes like forests,
wetlands, and grasslands traps
rainwater and snowmelt and allows
them to filter slowly into the ground.
In contrast, impervious (nonporous)
surfaces like roads, parking lots, and
rooftops prevent rain and snowmelt
from infiltrating, or soaking, into
the ground. Most of the rainfall
The loss of infiltration from
urbanization may also cause profound
groundwater changes. Although
urbanization leads to great increases
in flooding during and immediately
after wet weather, in many instances
it results in lower stream flows
during dry weather. Many native fish
and other aquatic life cannot survive
when these conditions prevail.
Increased Pollutant Loads
Urbanization increases the variety
and amount of pollutants carried
into streams, rivers, and lakes. The
pollutants include:
• Sediment
• Oil, grease, and toxic chemicals
from motor vehicles
• Pesticides and nutrients from
lawns and gardens
• Viruses, bacteria, and nutrients
from pet waste and failing septic
systems
• Road salts
• Heavy metals from roof shingles,
motor vehicles, and other sources
• Thermal pollution from dark
impervious surfaces such as streets
and rooftops
These pollutants can harm fish and
wildlife populations, kill native
vegetation, foul drinking water
supplies, and make recreational areas
unsafe and unpleasant.
Clean Water Is Everybody’s Business
URBAN RUNOFF EPA 841-F-03-003
Relationship between impervious cover and surface runoff. Impervious cover in a watershed results in increased surface runoff. As little as 10 percent impervious cover in a watershed can result in stream degradation.
Protecting Water Quality Agenda Item #5.5.
Managing Urban Runoff
What Homeowners Can Do
To decrease polluted runoff from
paved surfaces, households can develop
alternatives to areas traditionally covered
by impervious surfaces. Porous pavement
materials are available for driveways and
sidewalks, and native vegetation and mulch
can replace high maintenance grass lawns.
Homeowners can use fertilizers sparingly
and sweep driveways, sidewalks, and roads
instead of using a hose. Instead of disposing
of yard waste, they can use the materials to
start a compost pile. And homeowners can
learn to use Integrated Pest Management
(IPM) to reduce dependence on harmful
pesticides.
In addition, households can prevent
polluted runoff by picking up after pets and
using, storing, and disposing of chemicals
properly. Drivers should check their cars
for leaks and recycle their motor oil and
antifreeze when these fluids are changed.
Drivers can also avoid impacts from car
wash runoff (e.g., detergents, grime, etc.) by
using car wash facilities that do not generate
runoff. Households served by septic systems
should have them professionally inspected

and pumped every 3 to 5 years. They should
also practice water conservation measures to
extend the life of their septic systems.
Controlling Impacts from New
Development
Developers and city planners should
attempt to control the volume of runoff
from new development by using low
impact development, structural controls,
and pollution prevention strategies. Low
impact development includes measures that
conserve natural areas (particularly sensitive
hydrologic areas like riparian buffers and
infiltrable soils); reduce development
impacts; and reduce site runoff rates by
maximizing surface roughness, infiltration
opportunities, and flow paths.
Controlling Impacts from
Existing Development
Controlling runoff from existing urban
areas is often more costly than controlling
runoff from new developments. Economic
efficiencies are often realized through
approaches that target “hot spots” of
runoff pollution or have multiple benefits,
such as high-efficiency street sweeping
(which addresses aesthetics, road safety,
and water quality). Urban planners and
others responsible for managing urban
and suburban areas can first identify and
implement pollution prevention strategies
and examine source control opportunities.
They should seek out priority pollutant
reduction opportunities, then protect
natural areas that help control runoff, and
finally begin ecological restoration and
retrofit activities to clean up degraded water
bodies. Local governments are encouraged
to take lead roles in public education
efforts through public signage, storm drain
marking, pollution prevention outreach
campaigns, and partnerships with citizen
groups and businesses. Citizens can help
prioritize the clean-up strategies, volunteer
to become involved in restoration efforts,
and mark storm drains with approved “don’t
dump” messages.

Agenda Item #5.5.
Response to Response to Comments: Prepared by John Milliken Inadequate Analysis and Flawed Findings in FEIR Section I: Hydrology and Water Quality The less than significant finding (LTS) in the FEIR concerning water quality and potential harm to the habitat of the endangered species in the adjacent Napa River is completely without merit. The EIR insufficiently identifies and fails to provide a level of analysis of the significant impacts of polluted runoff, increased storm water volumes, and diminished re-charging of the underlying aquifer (affecting summer stream flows) that will be caused by the project. Not only are the significance of these impacts ignored, corresponding mitigations to lessen their effects are not proposed either.
The credibility of the entire EIR process is in question if you agree with the presumption that an 87 unit development, located in a flood plain, with acres and acres of impervious surfaces (roads, driveways, parking lots, walkways, roofs, patios, utility pads, etc.), will not have any significant impact on water quality, groundwater recharging, or the amount of runoff generated by the project. The likelihood of significant impacts to water quality and harm to protected species is even more pronounced if the cumulative effects over many years are considered. Not identifying cumulative impacts to hydrology and water quality is another serious failure in this FEIR.
Instead of identifying significant impacts and proposing mitigations, the FEIR spontaneously claims that, ”it was abundantly clear that potential impacts to aquatic resources that could potentially result from water quality or runoff flow caused by the project would be insignificant and, therefore, not a significant impact to aquatic resources on, adjacent to, or downstream of the project, including to fish, fish habitat, or fish movement.” This claim was made in spite of a 6 page report to the contrary prepared by a fisheries biologist expert, Jeff Hagar, who was commenting on the inadequacies of the DEIR. Instead of heeding Mr. Hagar’s meticulously researched and documented analysis, the FEIR took a pass on his findings and deflected them all away by claiming that the project will have to apply for an EPA NPEDS (National Pollutant Discharge Elimination System) permit and this will mitigate everything. Interestingly, Table III-1, Required Discretionary and Ministerial Permits and Approvals, from the DEIR does not even list a NPEDS permit.
A General NPED Construction Permit’s scope applies only to storm water runoff during a project’s construction phase and is an important protection for water quality. However, there are no impacts identified in the FEIR concerning Hydrology and Water Quality post construction singularly or cumulatively. And if there are no impacts identified, there are certainly no mitigations offered either. As it turns out, this is a common theme of both the DEIR and FEIR. The analysis of the DEIR was preoccupied with the environmental impacts of the construction phase of the project and tended to ignore/neglect the post construction and cumulative impacts of the project, another example of improper CEQA mandated analysis.
So what types of mitigations could have been proposed by a proper analysis? Quite a few, if you had just perused the EPA’s brochure on the impacts of Urban Development Guidelines. Somehow this readily available information was ignored or not even considered in both the DEIR and FEIR. Which leads one to ponder the competence of the firm that was hired to prepare both of these reports.
Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the Agenda Item #5.5.
ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
Urbanization increases the variety and amount of pollutants carried into our nation's waters. In urban and suburban areas, much of the land surface is covered by buildings, pavement and compacted landscapes. These surfaces do not allow rain and snow melt to soak into the ground which greatly increases the volume and velocity of stormwater runoff. In addition to these habitat-destroying impacts, pollutants from urban runoff include:
•Sediment
•Oil, grease and toxic chemicals from motor vehicles
•Pesticides and nutrients from lawns and gardens
•Viruses, bacteria and nutrients from pet waste and failing septic systems •Road salts
•Heavy metals from roof shingles, motor vehicles and other sources •Thermal pollution from impervious surfaces such as streets and rooftops These pollutants can harm fish and wildlife populations, kill native vegetation, foul drinking water, and make recreational areas unsafe and unpleasant
Controlling Impacts from New
Development
Developers and city planners should
attempt to control the volume of runoff
from new development by using low
impact development, structural controls,
and pollution prevention strategies. Low
impact development includes measures that
conserve natural areas (particularly sensitive
hydrologic areas like riparian buffers and
infiltrable soils); reduce development
impacts; and reduce site runoff rates by
maximizing surface roughness, infiltration
opportunities, and flow paths.
As stated in the DEIR, permit approval is not a substitute for thorough and complete environmental review. From the DEIR:
E. DISCRETIONARY ACTIONS
Agenda Item #5.5.
It is anticipated that this EIR will provide environmental review for all discretionary approvals and actions necessary for the proposed project. A number of permits and approvals would be required before the development of the project could proceed. As Lead Agency for the proposed project, the City of St. Helena would be responsible for the majority of approvals required for development. A list of required permits and approvals that may be required by the City and other agencies includes, without limitation, those provided in Table III-1.
The FEIR does NOT provide environmental review for the discretionary approval and actions necessary for a NPEDS permit.
Given that the project site is located on the floodway of a river that has been designated as impaired for endangered fish species, a thorough EIR analysis, that strictly follows CEQA guidelines, is even more of an imperative. It would surely be a mistake to rely on solely NPEDS permitting standards in such an environmentally sensitive area. The project site is so close to the impaired river that options for improving water quality are extremely limited. Quite simply, polluted high sediment runoff from the acres and acres of impervious surfaces will enter the gravity operated storm water basin and then exit directly into the impaired river. Although it is predicted that storm water handling facilities will have the capacity to handle storm water flows from the project, there is no denying that the level of water pollutants and quantity of runoff into the river from the project will be far greater than pre-project levels. The DEIR refers to studies of sediment TMDL being developed with the goal of reducing sediment discharges into sensitive fish spawning areas. However, these studies are ongoing and TMDLs have not yet been established. Until they are, the FEIR should not assume that the issuing of a NPEDS permit will reduce project water quality to less than significant. This is best summed up by the fisheries biologist, Jeff Hagar:
This comment brings up another shortcoming of the FEIR, there are no comments in regard to the DEIR from other government and private stakeholders working to restore endangered fish habitat just south of the project. Should not there have been comments solicited from California Coastal Conservancy, U.S.
Army Corps of Engineers, Napa County Resource Conservation District, California Fish and Game, California Water Quality Control Board, and a group of 23 private property owners with property that borders the Rutherford Reach, the 4.5 mile stretch of the Napa River between St. Helena and Oakville? Were these entities ever contacted and asked to comment on the DEIR and allowed to express concerns about the projects impacts on their environmental restoration efforts just to the south? As the lead agency responsible for producing an EIR that will adequately inform government decision makers as well as the public, the City of St. Helena should instruct the EIR consulting firm to re-evaluate the preparation of the Hunter Development EIR and recirculate a document that meets the standards established by CEQA. The deficiencies of the FEIR concerning Hydrology and Water Quality documented above are just one of the many areas of this FEIR that provide inadequate and incomplete analysis of the project’s impacts on environmental quality.

Hi Cindy – please add these questions to the EIR
Hope all is well. Weird weather, right? From 80 degrees to rain storms and 45 degrees. What season is this?
Cheers,
Ann
Question #1
How will this project affect the St Helena city groundwater wells at the Stonebridge locations? The project plan states it will provide all the landscaping water for 87 houses’ lawns, flowers, bushes, gardens, carwashes, and other watering uses. The number could be 20-40 units higher if the project includes regulated affordable housing. Since the well is located next to the Napa River upstream from the City of St Helena wells that supply our community with water, what mapping will be conducted to determine if the aquifers are connected? If they are connected, then drawing large amounts of water from the same groundwater source needs to be assessed so it does not deplete the City wells supply. Who will conduct the mapping? How many groundwater data points will be included in any mapping exercise? Will it be a sufficient number to adequately determine that the Hunter well is on an aquifer that is separated from the city aquifer? This question must be answered accurately, because the city relies on the groundwater Agenda Item #5.5.
from these 2 wells as a critical source of water in times of drought when Bell Canyon is depleted. (Example – the drought resulting in exposure of large portions of the bottom of the Bell Canyon reservoir.
Question #2:
The project area is in a low lying wet area on the historic floodplain for this part of the Napa River. It has flooded numerous times over the last 20-30 years. Even in non-flood years, large portions have remained wet during the summers, to the point that vine growth and production was hampered due to the wet soils. Presently, this area is covered with standing water during and after rains with water depths often 10-12 inches deep. The project will add millions of gallons (25 acre feet) of landscaping water annually to an area that has never been irrigated.
Will the addition of paved surfaces, construction pads, streets and structures cause compaction of the soils/subsoils in the area? Will this cause subsidence or instability of structures in and around the project area over time? Will subsidence cause new unknown flooding issues? Question #3:
There is an existing subsoil study on the project area that shows what is considered to be the profile of a historic pond, which is typical in areas proximal to meandering rivers. Since the area is a known liquefaction zone in an earthquake prone location, and soils of this type can be unstable, how will this affect the safety of the homes and the structural integrity of the levee in an earthquake or major flood?

Subject: Scoping comments on Hunter EIR
Date: Thursday, April 12, 2018 1:37:08 PM
I’d like to submit the following comments for the Scoping of the Hunter EIR Groundwater usage on the site
The estimates of historical groundwater usage on the site need to be redone. The previous EIR made some highly questionable assumptions about historical groundwater usage, leading to an estimate of pre-flood-project groundwater demand on the site of 22 AF. There are two errors in the consultant’s methodology rendering this estimate much too high.
1. The consultant assumed that all of the vineyards on the site were historically irrigated. There is little need to irrigate this wet vineyard and there is no evidence that there has ever been an irrigation system on the site, so the assumption that the well was used to irrigate the entire site is unfounded. There are no remnants of piping or any other irrigation components currently. And, vintners adjacent to the site who have lived here for decades do not recall there ever being such a system. The property is adjacent to the river and is one of the wettest vineyard locations in the valley. There is little need to irrigate there. Adjacent vineyards which are updip and drier are all dry farmed. If the assumption is to be made that irrigation once existed for the entire vineyard, it is incumbent upon the consultants to prove that such a system existed.
2. The consultant assumed vineyard irrigation rates from the Oakville area, a much drier area farther from the Napa River. Even if this area was ever irrigated, Oakville irrigation rates are too high. Again, this is a wet vineyard which would need water only rarely in the driest of years, if at all.
Therefore, historical groundwater pumping on the site was likely localized, sporadic and minimal.
The actual usage would be a small fraction of the 22 AF. What are the new estimates of historical production? What data are used to justify those estimates? Impacts on the Napa River, including fish
The existing groundwater well on the site is only hundreds of feet from the Napa River. If the aquifer being accessed is at all connected to the river, then the well is drawing down from the Napa River, impacting river flows and fish habitat. What is the connection to the Napa River? How much is the impact on river flow from pumping on the site at different rates? A groundwater hydrology study should be undertaken to determine the connection to the river.
Impacts on City Groundwater Supply Wells
The existing groundwater well on the site is updip of City water supply wells and the proposed levels of use could impact City wells. Is it the same aquifer? How would pumping on the site affect groundwater levels in the City wells, at different rates? A groundwater hydrology study should be undertaken to determine if there is a connection to the City’s groundwater supply wells and the potential for drawdown of those wells.

Subject: Hunter EIR Scoping Comments
Date: Thursday, April 12, 2018 9:20:20 AM
CindyBelow are my comments regarding the scope of the Hunter EIR.
1. The EIR for the Hunter Project cannot be done until it is conclusively determined whether or not the Hunter Project qualifies for the 40% affordable housing benefits, including priority in water and sewer connections, use of prior year surplus units from the Growth Management System (GMS), etc. The reason for this is that the environmental impact is completely different if the benefits are applied to the project than if they are not applied. An example is that if the project qualifies under the inclusive housing and affordable housing ordinances, then the entire project can be completed in 2 years, according to the developer. If the project does not qualify, then the Hunter Project could take up to 10 years to complete, assuming very few, if any other houses are built in St. Helena during that timeframe because the project would be limited to the annual 9 units allowed under the GMS. It isn’t hard to see that the environmental impacts are quite different under these two scenarios.
Before the EIR begins, it has to be determined if the Project qualifies for such benefits or not.
This decision cannot run on parallel tracks with the EIR and then come together at the end, as Noah Housh suggested at the neighborhood scoping meeting last month. For the EIR to be accurate, the EIR consultants must know what scenario applies before the EIR begins. And, in cases like this, it does matter to CEQA if the housing is market rate or affordable because the priority benefits derived from hitting a 40% affordable housing rate under City ordinances changes that environmental analysis. In this case, it is not the affordability of the housing that affects the CEQA analysis, but the priority benefits given by the City and/or the state that changes the impact on the environment from building this project.
The prior Hunter Project EIR inappropriately assumed (without confirming) that the Hunter Project would qualify for the priority benefits stemming from the project complying with the inclusive housing and affordable housing ordinances at the 40% rate. That assumption cannot be part of the current EIR process because it likely will make the EIR inaccurate.
If the developer does not want to show to the satisfaction of the City Council that their current proposal completely meets all of the City’s inclusive and affordable housing requirements to qualify for the 40% priority benefits, then the EIR should be done without giving any credit for any of those benefits before the EIR is started. At the very least this would change the environmental analysis from a two-year project to a potential ten-year project with ongoing environmental impacts.
If the EIR assumes the project will qualify for the 40% rate and if it is later determined that the current project cannot meet the inclusive housing and affordable housing ordinance requirements without resubmitting a tentative map, then the City would be in the position of looking at yet another Hunter EIR exercise. It would make more sense to make that determination now.
2. The Hunter Project EIR has to take into consideration the cumulative impacts of the 17-acre Agenda Item #5.5.
Hunter Project, along with the 24-acres of Key Opportunity Sites (sites 1, 2, and 6 on page 134 of the Housing Element Needs Assessment), which begins about 3 blocks from the Hunter Project and extends south across Pope Street. These cumulative sites will significantly impact surrounding streets and the Pope Street bridge. Such cumulative effects will undoubtedly impact the environment and have to be taken into consideration in the Hunter Project EIR.
3. The Hunter Project EIR needs to consider the environmental impacts resulting from a potential levee failure. CA Government Code §65302(g)(2)(A)(vii-viii) requires that St.
Helena include a levee failure map in its General Plan Update to show areas that would be inundated in the event of a levee failure. It will be important to have such an inundation map to show the environmental difference between the situations where the land behind the levee is undeveloped, as it is now, and the situation where the land behind the levee is covered over with asphalt and houses, which is a situation where there would be significantly less permeable land for flood waters to be absorbed. The environmental differences between these two situations would likely be significant.
Of additional environmental interest is that fact that the area closest to the Napa River where the levee is located is considered a high liquefaction susceptibility area (Figure 4.K-2 in the General Plan Update) and liquefaction is a well-known and significant cause of levee failure.
4. The EIR for the Hunter Project has to assume the project can be built out to the maximum density allowed resulting from any density bonuses provided under city ordinances and state law, even assuming the current project does not now show such a density bonus in the “deemed complete” tentative map. The current owner and/or developer could decide after an EIR is approved to sell the property and the new owners could apply for the density bonuses prior to seeking building permits. At that point it would be too late for the EIR to take into consideration the increased housing units, population, cars and other environmental impacts because the EIR would already have been completed and approved.

Hello Noah,
Thanks for hosting the meeting last week. As I mentioned at the meeting, kicking off the EIR seems very premature and a waste of time and money.
1. The applicant is still formulating and the City still reviewing the affordable housing component. How can we comment on something that is incomplete, and has not been reviewed by the city?
2. As was brought up by Planning Commissioner Grace Kistner, our municipal code requires that in order to qualify for density bonuses (without which this project will never get built) the project needs 20% AFU for sale. This will almost certainly require a revised subdivision map, and likely a brand new subdivision application. It seemed to me that the developer has not thought this project out very well as is making it up as he goes along. With this understanding Agenda Item #5.5.
an EIR at this juncture makes no sense.
3. This project is extremely unpopular by a majority of residents and a hasty ill-planned EIR process will most certainly be vigorously challenged. Why not pause and let the developer get his plans together first, it is not fair to ask the community to weigh on a moving target.
Sincerely,
Chuck Vondra – Principal, Sr. Consultant

Cindy,
The first photos are showing up now. Can you tell me if you receive this with the first 7 photos in it? Just hit reply if you would. Thanks.

Dear Cindy,
Please consider these comments regarding the scope of the Hunter EIR.
An earlier EIR dismissed flood risk for the Hunter Property behind the levee as "less than significant" as shown below ...
Agenda Item #5.5.
That citation reports the "potential flooding impact, under CEQA, is less than significant." With due respect to all, I consider the flood risk behind the levee and its potential consequences to be substantial, and ask that the flood risk be thoroughly studied so St. Helena residents and taxpayers do not become liable for damages occurred on that property when the levee alignment violated St.
Helena's own 1993 General Plan, which contained this provision ...
Agenda Item #5.5.
... that "grading and earth filling within the designated 100-year floodway should not be permitted." Unfortunately the Vineyard Valley development was developed directly atop the floodway to the Napa River, as shown on these photographs ...
and from the east side of the River ...
Agenda Item #5.5.
These photos show that the floodwater trapped behind the Vineyard Valley cinder block wall did not overtop the riverbank, but instead drained naturally from the watershed northwest of Vineyard Valley, toward the historic floodway now blocked by Vineyard Valley.
Disruption of that historic natural floodway caused both floods in 1986 and 1995 that caused over $100 Million as documented by City Manager Johansson in his Project Summary report to Assemblywoman Noreen Evans and Senator Pat Wiggins ...
Agenda Item #5.5.
Engineers know as basic safety practice not to obstruct floodplains, as confirmed below in St.
Helena's 1993 General Plan ...
Agenda Item #5.5.
Unfortunately that basic practice was ignored in the levee alignment, which bisects the very floodplain that caused the 1986 and 1995 floods that caused over $100 Million as reported above by former City Manager Bert Johansson.
After the 1986 flood, in his letter of August 14, 1986, to developer McDonnell, then City Engineer Jack Meade warned Mr. McDonnell against reconstructing Vineyard Valley on its floodway blocking site ...
Agenda Item #5.5.
... 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 #5.5.
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 #5.5.
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 #5.5.
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.
