Summerhill Homes may be building --get your free sand bags from Danville

Original post made by NO ON SUMMERHILL!, Danville, on Mar 16, 2012

Yes, Danville has announced today that is is "once again providing residents with sand and bags to assist in flood prevention and control efforts".

Why is there flooding and erosion in Danville? Because OVERDEVELOPMENT IS CAUSING FLOODING AND EROSION!!

Now Danville is considering the approval of YET ANOTHER DEVELOPMENT that will add to flooding and erosion along Green Valley Creek in the Diablo Road corridor. SUMMERHILL HOMES is seeking to build 123 or more dwellings that will cover many dozens of acres of open agricultural land with impermeable surfaces. What does that mean to the hundreds of homeowners in the Diablo Road corridor that live along Green Valley Creek? EROSION WILL GREATLY INCREASE (because of the higher than normal waterflows that will flow for many hours from SummerHill's detention basin) and FLOODING WILL INCREASE because the detention basin will undoubtedly OVERFLOW from time to time because it is insufficient to handle flows or it is poorly maintained.

Please email Danville Council Members and Planning Commissioners (see Town of Danville website for email addresses) and tell them Danville can SAVE MONEY ON SANDBAGS by VOTING NO ON SUMMERHILL!!

I already have to carry flood insurance because I live on Green Valley Creek. After SummerHill is built, will my already expensive flood insurance rates go up because there will be a greater risk of flooding/erosion damage to my property??

If you have any doubt about the truth of the above statement regarding increased flooding and erosion along Green Valley Creek that will be caused by the 123 or more dwellings of the Summerhill Homes Development, take a look at our current creeks and run-off areas now. The recent rains have GREATLY enlarged them!! Can you imagine what will happen if the Summerhill Home Development is approved?!?

I live near St. Timothy's Church along Diablo Road. The creek has so eroded its banks that the road is nearly collapsing into the creek in a number of places. Who is going to pay to shore up the banks and protect Diablo Road? If you think SummerHill will, I have some property in the desert I will sell you! Guess who paid for the $1 million plus repair of the highly eroded Diablo Road/El Pintado Road bridge and adjacent sidewalk? Developers? Guess again----Danville TAXPAYERS!!

Buncha hysterical hooey. Area didn't flood in last year's season-long deluge, nor at any time since I moved here in the 1970s. Everybody knows that the real problem is traffic, so please don't try to mislead us by cloaking your argument in the environment.

Get together with all the stakeholders, including Summerhill, and get creative -- work it out, instead of cluttering up everybody's lives with this nonsense.

Check your facts, C Mudge. Start by looking at the Contra Costa County Flood Control District's comments to Danville on the Notice of Preparation for the SummerHill EIR. It is well-known that Green Valley Creek has portions insufficient to handle a 25-year Flood. Danville's standard enshrined in its 2010 General Plan is to protect all properties along the creek from 100-year Flood levels. In other words, Green Valley Creek is far from meeting Danville's own standards for flood protection.

Glad you agree traffic is a terrible problem in the Diablo Road corridor. But flooding/erosion is a REAL PROBLEM that SummerHill will worsen.

I can look in my backyard next to the creek and check the facts. No flooding, ever. The only thing with more capacity than that creek bed is your group's tendency toward hyperbole instead of collaboration.

The traffic is nobody's surprise -- it's been that way for 20 years. Work it out, THEN let us all know.

Sorry, C-mudge. You should venture out of your hole a little farther. The entire Green Valley Creek is in a FEMA FLood Zone! Just because you personally have never experienced flooding doesn't mean it does not occur in other reaches of the creek---duh! And let's not forget about erosion, or are you denying that, too? You might ask about that next time you are at work at SummerHill's San Ramon offices.

I'm glad we agree that traffic is a huge issue with teh SumemrHill development. But as to Mudge on flooding/erosion, I'm reminded of the man who looks to the east in the evening, and denies that the sun is setting. Mudge, your backyard is an anecdote, not systematic data. Unless you think the Contra Costa County Flood Control District is also disposed to "hyperbole," I'll just let their concerns about the SummerHill Development speak for themselves. These are their words in response to the Town of Danville’s Notice of Preparation, and are direct quotes:

1.“The developer needs to show that the proposed project will not exacerbate the existing capacity issues on Green Valley Creek by increasing peak volumes and duration.”

2.“We are concerned about the potential for increased erosion within the reaches of Green Valley Creek downstream of this project.”

3.“We are concerned that Green Valley Creek will be affected by the secondary storm drain system, which appears to be designed to prevent minor tributary drainage flows upstream of the proposed development from flowing through the development…”

4.“The Town of Danville (Town) and the Developer should be made aware that residences adjacent to East Branch Green Valley Creek…downstream of the Subdivision, have reported flooding and erosion issues.”

5.“The FC District and the Army Corps of Engineers have performed studies that show that Green Valley Creek downstream of this project does not have sufficient capacity for the 100-year flow event considering the ultimate build-out condition.”

C-Mudge makes a good point - "work it out". That's what we are trying to do. But voicing our views on the project and raising awareness of serious and very real concerns is part of the process of working it out. In addition to concerns about SummerHill's project on traffic, flooding, erosion, the environment, schools, aesthetics, pollution, etc., we are concerned that these issues will be white-washed. C-Mudge is a perfect example of that - he/she denies there is even a problem. But there is a concerned group of ciizens who feel otherwise and have the proof to back up their concerns. Airing those concerns is an important part of "working it out". So I encourage everyone to get involved and look at the facts. We all live daily with the traffic issues. Less obvious is the flooding and erosion issues so I am grateful to the folks who are making us aware. Like someone previous pointed out - that big fix downtown on Front street was caused by erosion which will only get worse with more development along the creeks. And after the developers have made their money we the taxpayers will be left holding the bag and paying the bill. So let's all stop denying there is a problem and instead shine a bright light on it. Then when the facts are available and clear we can do as C-Mudge suggests and work it out. But let's stop the white-wash first.

I have pictures from last year's "deluge" in my backyard! The runoff was unbelievable and at times scary. And, as it has already been said, flooding/erosion are not the only issues. Traffic is a Huge inconvenience for everyone in this area as it is now! Imagine the added traffic from this proposed development. This will come to fruition if everyone doesn't get involved and let the town know that the the proposed project is unacceptable.

You are so right, concerned homeowner. Everyone has to get involved before the Town approves this ridiculous SummerHill Homes project for the Diablo Road corridor. And believe me, I have lived in Danville most of my life, and once a project gets this far, it takes a huge public outcry to derail it. SPEAK NOW OR IT WILL BE OVER BEFORE YOU KNOW IT!!

Elections for town council are in November! Last year, the 2 council members that were up were unopposed so they were automatically returned to office for 4 more years. Let's elect 3 new council members in November and make sure they are ones that will listen to the will of the people, and not be in the pocket of large landownerS and developers looking to reap speculative profits on our backs!
