Purissima Road that has recently come to my attention. I understand that the decision is being considered by you towards approval for further steps in the process. Our new neighbors, Amin and Suzanne Vandat,. at -26520 Purissima Road, has recently submitted plans for razing down the current house and building a new set of 'structures in its pjace. Because of the location of our land, and where the structure will be, I have serious concerns about its impact on the town's general habitat, and specifically on our lifestyles ; My specific concerns are: By building a large 7000 sgftt two story structure in an area where all other houses are subdued and well -blended with the natural .habitat, this structure .will be serious affront to the Town's charter for preservation.ofthe. rural-atmosphere.ofthe foothills and orderly and unhurried growth. Like a lot of other residents, I moved to Los Altos Hills to enjoy the natural views of the . hills, sky and greenery around me. Like all other of my neighbors I limited my development on my land to give everybody, and- enjoy myself such magnificent' vistas. "The previous owners' house whiclr�-isalso>followed..timsarire..... . principles. But by constructing such a large structure so close to my property line, and at a height that obstructs and boxes in my view from my.,)own living -room -let alone my front yard- I feet the construction of this high structure so close to my property will be robbing me of the most important aspect of Los Altos Hills life that I hold precious. My driveway that goes from the major part of my land to Purissima Road is my only access to the outside world. When this structure comes up, it will obstruct most of the driveway from my direct line -of -sight from my house. This is a major problem because: [Recipient Name] November 21, 2012 Page 2 My children (ages I 1 and 8) play on that driveway quite a bit, and I would be seriously concerned about the prospect of them getting hurt in the process away from my direct view The obstruction could allow people with bad intent the opportunity to sneak in and hide without us being able to see.themcausing serious security issues. We use the east and north side of our land as private backyard where we have. quiet family time =away from gawking eyes. With the new structure so close and so high. -with windows facing our way, we would not have any privacy whatsoever when we use those areas. That will make us feel like a prisoner in our house and would be definitely a big change from our today's lifestyle. - The I-280 highway is on the southwest side of our land, and we have a flat land on the east side of our land that we use for normal backyaid usage. "`While the. highway "produces a lot of noise, today our one-story house obstructs most of it that would have affected that land, while the rest propagates over the rooftop. The new structure is supposed to be a two-story structure. That will' make it a reflector for the noise. that propagates over our rooftop, and'make it bounce back the'noise into the backyard -severely restricting our. quality -of -life. A large part of the neighbor's -structure will be' built in a depression in between our house and Purissima Road. That depression gets filled up with water in heavy rains. Building two houses (one main house, one annexe), a swimming pool, paving structures, and other developments on that land would mean the water would have even less place to go to, and will end up flooding our driveway. Overall, this current building plan -is a serious nuisance, which I respectfully request the Town to obstruct and carefully review for all the above problems it ;may cause. Sincerely, _ Debarag N. and Bishakha Banerjee Debarag N. and Bishakha Banerjee 26570 Purissima Road Los Altos Hills, CA 94022 March 19, 2013 Planning Commission Town of Los Altos Hills 26379` Fremont Road Los Altos Hills, CA 94022 Dear Members of the Planning Commission: I reside with my wife and two small children (ages 11 and 8) at 26570. Purissima Road. My property.is ddirectly adjacent (300 linear, feet across the entire front and right side of my house) to the one at 26520 Purissima Road (Vandat house); which I understand the current owner to have submittedplans for razing down and building a new set of structures in its place. . I. understand.that the.decision is being considered by you towardsapproval for further . steps in the process. My specific; concerns are: • My Property's View Today we enjoy a nice bucolic view o f open skies, open vistas, and many hundreds of yards of native California scenery — without any neighbors' houses, ' fences, or other outdoor structures in our sight. This is: precisely the -reason we moved to Los. Altos.Hills — as I am sure, you all, have - and the reason why.anybody, moving to LAH;values the Town — raising property values: for all. By building so close to our land and by proposing to build a 6 -feet high fence right up to our property line, and by proposing to plant tall trees right next to the line, the Vandats are proposing to rob u§ of everything we hold precious. This will also cost us considerably in terms of the value of our land — bringing our property values_ considerably down. • : My family's Privacy I.have large -window' walls. along the entire front of my house: I am at a higher plane than the Vandat house in. front of me. The Vandats propose to ,build just 30 feet away from the property line. While I understand.this to - consistent with the town's.. guidelines, given the elevation of our land and the unique. situation of their new construction,. the protrusion of their new structure at the Northwest corner and the "in-law quarters" will be able to directly look into our living areas. We too will be able to look into their living quarters, March 19, 2013 Page 2 making it extremely uncomfortable for us. My children often play -in our front yard and meadow, and there would. be no privacy for them whatsoever. When setbacks and other mechanisms were designed, the Town had quiet, nonintrusive residents in mind. However, we have already seen examples of intrusive behavior where the Sheriff s deputies had to intervene to restore peace and quiet when extremely loud music emanating from 26520 Purissima intruded on the privacy of -neighbors on an otherwise quiet Sunday afternoon. If they are allowed to build closer than.they currently are to the property line (along with substructures and pool), the music and the noise from pool parties or house parties would be unbearable, resulting in a complete lack of privacy for us. • Fences and trees coming up to hide our views further The proposed fences and "screening", vegetation at the 26520 Purissima property line will obstruct.our views further, including impeding our visibility down our.long'driveway. We share part of that driveway with our neighbors at 26630Purissima (Mr. and Mrs:. Shakernia), which adds to the vehicular traffic on the driveway. We also jive=quite inland (about 700 feet) compared to the entrance at Purissima. Being able to see Purissima Road from our -house, especially where it meets our.driveway, is of paramount security interest to us. The lack of visibility on my own long driveway could lead toaccidents; say for example — when my eight year old son or eleven year old daughter was walking down the driveway while doing mundane chores'like taking out the trash. That isnot acceptable. It could also prompt miscreants and burglars to.lay in hiding, or otherwise surprise us and other security considerations. • Rural character of the Town is being destroyed It is the charter of the Town to be dedicated to preservation of the rural atmosphere of the foothills'and orderly and unhurried growth.:In fact,in. the 2011 LA-H.Resident<suryey,- 92.6% of residents agreed that the intent of our founding -documents was to-preserve,our= rural environment. The plan for review before you does not preserve that rural environment; 1. it destroys:it. • Mansions of this size relative to their plot size are -obstructive to and'inharmonius with their surroundings A few years ago, a similar question was brought forth for the Planning Commission, where a plan for development of an almost identical structure at 26462 Puh sima Road (only 2 houses away from the one under question today) was presented to the commission. After that house was allowed to be built, -the result has b4.een horrible. The house today looks like an alien structure sitting among surroundings it really does not belong in, while at the same time completely obscuring ;from view the'Kirkpatrick house behind it — which had -been there for 30 years, and decimating the Kirkpatrick property values. March 19, 2013 Page 3 That is the result of allowing mansions of this size in lots that are too small for them. Since that building has been constructed, its neighbors — Bob and Pat Kirkpatrick, and Ken Daniel, amongst others - have regretted the presence of such a house in the neighborhood. (See attached petition from neighbors). I hope the Commission does not repeat the same mistake again. • Water flow Between Purissima Road and Hwy 280, a seasonal water channel runs South -East to North-West. During the rainy season, water flows in from other properties into the land at 26520 Purissima, and then flows through a storm gutter installed under our driveway, before flowing further down. This drainage system had been in place for decades and had been proven to be adequate — till the construction of the mansion at 26462. This January, we observed the extra water resulting from the lack of absorptive surface at 26462 produce so much volume that it clogged up the drainage pipe, and overflew over our driveway by as much as 4 inches — on a year of relatively modest rain. The proposed construction is situated in the same drainage channel, and is expected to add an equivalent load of extra storm water —in addition to :the water already coming down from the North-West. This means our drivewaywould get further inundated at times of storm. Note that this problem is not addressed by the catchment system they intend to implement — as at times of storm the external water flowing through from other land to the North- West is so much that it raises the water table enough to overflow any catchment mechanism. Also, if the experience of allowing the mansion at 26462 is anything to go by, adding such catchment systems has proven to be entirely futile in face of storm water that flows through this part of Los Altos Hills. Overall, this current building plan is a serious nuisance, which I respectfully request the Town to obstruct and carefully review for all the above problems it may cause. Specifically, I request you to mandate:: ... . • Moving the closest parts of the structure as planned another .30 feet North-East of where it is planned. The Vandat property has a lot of land in the front, and the new design can easily be brought forward, closer to Purissima. • Bringing down the roof profile of the higher story by 3 feet • Upgrading the drainage channel situated under my driveway to account for the additional storm -water so that my driveway does not inundate • Require any fencing structure to be set back by 30 feet from the property line • Require any additional screening vegetation to be no more than 6 feet from the ground level —after reaching which height they should be trimmed.

As a result of the developed area at 26462 Purissima Road which is a few hundred feet up -stream from the 26520 Purissima Road lot, existing driveway culverts have been overwhelmed. This has happened during recent and earlier rain storms. This situation occurred during a seasons when rain fall was weU below normal. On March 24, 2011, during that rain storm, there was a short burst of heavy rain. This burst resulted in the flooding situation shown here. This shows our driveway at 26470 Purissima Road, and the driveway at 26500 Purissima Road. The source of this flood water was from the pond that formed behind the culvert, and over the driveway at 26462 Purissima Road shown here. Since rain runs off impervious surfaces quickly, causing flooding, new building requires temporary storage of burst rainfall That is why the county required these pipes to be installed at 26462 Purissima Road. From the Santa Clara County building requirements: Drainage Manual 2007 County of Santa Clara, California Page 77 Stored water in a retention facility shall percolate into the ground and return to its original elevation within 24 hours of the cessation of precipitation from a design 100 - year, 24 - hour rainfall event over the basin's tributary area. I do not think the burst of rain in March 2011 or subsequent storms were 100 year events. I do not think the retention facility was back to its original elevation 24 hours after the rain stopped. The system does not meet flood control requirements or protect down -stream property from damage. However, Residual seepage from this structure long after the end of the rainy season has produced puddles in the neighboring lot. This situation has caused concern regarding the stagnant water and the health effects of a mosquito breeding ground. The rain water containment system required by the county, and increased in capacity by the Town, on this up stream development, failed to meet any flood control objective and created other potential problems Based on this failure, additional MDA for the 26520 nroiect must be denied to avoid additional down stream flooding. G R Kirkpatrick 26470 Purissima Road Los Altos Hills, CA To the Planning Commission, Town of Los Altos Hills ATTACHMWIP PRESERVE THE RURAL CHARACTER OF LOS ALTOS HILLS MAR 2 5 2011) Prevent building mansions on lots that are so small for them that they crowd out the neighbors TOWN OF LOS ALTOS HILLS We thQ.residents of Los Altos Hills cherish the rural atmosphere of the foothills, and urge the Town of LosAitos Hills to uphold, its charter of preservation of the rural atmosphere of the foothills and orderly and unhurried growth by preventing the,building of large mansions on lots that are so small for them that they crowd out the neighbors' views and frontage. Recently the Puriss a Road region of Los Altos Hills has seen a spree -of building oversized mansions on lots that are so small for them that they crow -out the neighbors: These buildings, like the one built on 26462 Purissima Road, look like an:alien structure surrounded by high fen es sitting among surroundings they really do not belong in, while at the same time completely obscuring from view pre-existing houses -behind them. Lately a new plan has been submitted for approval to the Town for constructing such a structure by Amin Vandat at 26520 Purissima Road —and putting up 6-feethgh fencing all around.its property line- thus obscuring other neighbors' houses that lie around it, and sticking up like an alien structure in an area where all other houses are subdued and well -blended with the natural habitat. Overall, this current.building plan is a serious nuisance, which we respectfully request the Town to obstruct and carefully review for - all'the above `problems Itmaycause. Specifically, we request you to mandate: • Moving the closest parts of the structure as planned another 30 feet North-East of where it. is planned Bringing down the'roof profile of the higher story down by 3 feet Upgrading the natural drainage channel running between Purissima and Hwy 280 to account -for the additional storm -water runoffsthat'such structureswould produce • Require ahy fencing structure to be set back by 30 feet from ;the property line • Require any additional screening vegetation to be no more than 6 feet from the ground level Signed Signature Name Address D G BA RA �A Nre I -TU 26 5 77 SS 1 j), Los A LTas 1♦jiLS YasAble" b12 Sjb:� 8 o L A ' ?_(r f v KrSSlivbf a G o� C�V JzpatP 2d1170 PvrrfGimc—, 4 yap"Hi�'rc if2iE' t- 41 o26c/76 P rSs/ I � bo�Kdb �R trT .26g7D Srivt,s.
