HomeMy WebLinkAbout3.1 Town Of Los Altos Hills October 28, 1998 Staff Report to the Planning Commission RE: REVIEW OF THE PLANNING DIRECTOR'S DECISION TO APPROVE A SECONDARY DRIVEWAY; LANDS OF SHIDELER; 27994 VIA VENTANA; FILE#175-98-ZP-SD. FROM: Suzanne Davis, Associate Planner SD APPROVED BY: Curtis Williams, Planning Director, RECOMMENDATION That the Planning Commission: Approve the request for a site development permit for a secondary driveway over a private access easement, subject to the recommended conditions in Attachment 1. CODE REQUIREMENTS Section 10-2.301(b)(6) of the Site Development Ordinance states that after notice and public hearing, the Planning Director shall review and act on applications for construction of a private vehicular access or driveway which results in a new or relocated access point to a public or private road. The proposed driveway is already existing, but is not presently paved. BACKGROUND On September 15, 1998, a site development hearing was held to consider the subject application. A number of interested neighbors attended the hea:ing, with both concerns and support being stated for the project. Following discussion and a presentation by the applicant, the Planning Director approved the application subject to conditions (see Attachment 2). DISCUSSION - As noted in the minutes of the September 15, 1998 site development hearing, there was considerable discussion and participation on the part of neighbors who access their properties from Via Ventana. The majority of neighbors supported the request to pave the lower portion of the access easement. Concerns about the proposal include preservation of oak trees, the visual impact of paving the driveway, drainage and safety. Tree Preservation The applicants submitted a letter from the project arborist stating that the oak tree on the Kells/Curtis/Gilbert property would not be adversely impacted (see Attachment 4). The letter also comments that excavation could damage tree roots, although none is proposed Planning Commission • September 15, 1998 Lands of Shideler Page 2 to complete the driveway. No trees or other vegetation are proposed to be removed to complete the paving. Visual Impact The applicants are proposing to use interlocking pavers for the lower driveway. This material is not a solid impervious surface as asphalt or concrete would be, and would allow some water to penetrate through. Stone is a more natural looking material and would better blend with the surroundings. The Commission may view the pavers that are stacked on the site, as well as the existing driveway to the Shideler residence which shows how the paving stones look when installed. Drainage The drainage has been designed so that the run-off to the Kells/Curtis/Gilbert property would not be increased. The driveway would be sloped towards the Shideler's lot and a drainage ditch would be installed along the driveway to direct runoff along the driveway to lower Via Ventana. The applicant has submitted a letter which explains the drainage system in detail (see Attachment 5).- S afety- The City Engineer does not believe that paving the driveway within the lower portion of the access easement presents a significant safety issue if used for ingress only. Signs stating that the road is one-way would be posted at the lower entrance off Via Ventana, and at the juncture of the existing driveway to the Shideler residence. There would also be a gate across the easement so that access is controlled. Because vehicles cannot legally drive down the lower portion of the easement, there will not be left turns made across or in front of the median with the oak trees. The Shidelers have agreed not to place a mailbox or their address at the beginning of the new driveway, so as to not call attention to it (condition #2). The road is proposed to be paved so there is an all weather surface and the applicants and other neighbors with rights to the easement have the convenience to use it to enter their properties from lower Via Ventana. Some neighbors indicated that there are safety concerns with the upper driveway access due to the sharp right turn required from Via Ventana. Lighting The applicants have not requested to install any lighting either at the entrance or along the new driveway. Staff has added a condition stating that no lighting has been approved. If any lighting is desired in the future, it would be required to be reviewed at a site development hearing so that neighbors would have input. Staff is available to answer any questions from the Commission or members of the public. - Planning Commission • September 15, 1998 Lands of Shideler Page 3 ATTACHMENTS 1.

ATTACHMENT 2 Minutes of Site Development Hearing Tuesday, September 15, 1998 City Council Chambers, Town of Los Altos Hills 3:00 to 4:15 pm Staff present: Planning Director Curtis Williams, Associate Planner Suzanne Davis Committee member present: Dexter Hake,Environmental Design &Protection Neighbors present: Jan &Jay Shideler(applicants), 27994 Via Ventana Victoria Gilbert &Kathleen Kells, 27990 Via Ventana Jen-ell Thomas, 27933 Via Ventana Pearl Abbott, 27899 Via Ventana Mary E. Compton, 27855 Via Ventana Anne Ward, 27947 Via Ventana - Robin Knutson, 27999 Via Ventana Tita Ware, 27743 Via Ventana - Staff noted that three letters had been received regarding this application, two insupport of the request and one voicing concerns. -One letter of support represents owners of three separate properties (Mr. & Mrs. Walter Babbitt, Mr. & Mrs. Charles Compton & Pearl Abbott) and the other was from Michael D. Laufer. The letter stating concerns was from Erik&Victoria Gilbert and Pavel Curtis &Kathleen Kells. Jay Shideler explained problems that have occurred on his property and along the private access easement, and went over the proposal to pave a 10 foot wide portion of the easement to allow ingress from Via Ventana. Paving stones would be used which will better blend with the environment, no vegetation is to be removed, the road would be one-way over the lower portion and would be gated to control access. He also addressed safety concerns. • Dexter Hake, Environmental Design & Protection Committee, noted that there are large oak trees in the area, and that they will all be preserved. The EDP Committee had no concerns. Kathleen Kells commented that the issue of using the lower easement road was discussed during the public hearing process for the Shideler's-new residence and that access was not allowed at that time. Mr. Williams noted that the original proposal included access through the median and cutting the median. Staff does not believe any decisions were made that preclude a secondary access to the Shideler property or use of the easement. Site Development Hearing Minutes September 15, 1998 Page 2 Pearl Abbott stated that the Shidelers have a right to use the easement. Victoria Gilbert expressed concerns about drainage. She and her housemates had drainage problems this winter; their property is below the Shideler and Yen properties and they experienced more runoff than in the past. Andy Compton pointed out that the original access to the Jones property (now Yen and Shideler) was from the lower point. The upper driveway isn't the safest location either (nine homes now access from that point). Victoria Gilbert wanted to make sure that adding pavement doesn't increase the drainage problem or direct more water onto her property. Often trucks using the private road can't make the turn at the bottom of the hill. Jerrell Thomas lives between the two access points for the private road and supports the request to pave the lower portion of the easement. Tita Ware is also in favor of the proposed access. Staff noted that the City Engineer has not determined that there is a significant safety issue with the proposed driveway since it is to be used for ingress only. Robin Knutson, speaking for herself and her mother Jeannine Knutson, wanted to make sure that the easement continues to be addressed as such, and that the driveway doesn't become a"road". Anne Ward asked whether the development area for the new driveway is counted against the two properties that the road runs over. Staff answered that the development area would not be counted against any of the property owners with rights to the easement (Shideler, Yen, Laufer, Capiaux, and Kells/Curtis/Gilbert) Kathleen Kells suggested the use of other type of pavers for the lower driveway so that it would be distinguishable from the main driveway and would blend in more and not be as noticeable. She also expressed a concern about the large oak on her property that would overhang the paved driveway. Staff asked the applicants to have an arborist evaluate the oaks along the driveway, to determine that there would not be any adverse impact to the trees. The applicants stated that Barrie Coate has already reviewed the plans and the trees, and that they would request a letter. In addition to evaluating the oaks, the safety issue will be re-evaluated by the City Engineer. Conditions of approval were reviewed, and two conditions were added restricting placement of the address to the upper entrance of the access easement, and requiring Fire Department approval of the new gate to be placed across the entrance of the lower easement.

The PG&E transformer has been moved and all of the work associated with it has been done. Concerning the drainage, I have gone beyond what is necessary to account for even the 100 years flood condition(cloud burst while the soil is super saturated). Here's how it is works: An 8"drain pipe has been placed under the road and extends to the first drain catch basin. From that point onward, the affluent rain runoff is carried through a 6"diameter drain pipe which empties just in front of the storm sewer located at the intersection of Page Mill Rd. and Via Ventana. The 6"drain-pipe will handle any affluent runoff particularly because the grade creates a significant"head"to enhance the transfer flow of water. Any runoff from the lower easement road will run into three drainage catch basins interspersed along this drain-pipe. Since the road has been regraded to slope into the hillside the runoff from the road will be caught in these catch basins. The drainage ditch running above the drain-pipe has been graveled to handle the direct runoff while preventing significant erosion. For the 100-yrs flood condition mentioned above(worst than the cloud burst with saturated soil condition witnessed by your's truly last winter during El Nino), if the 6" drain pipe is insignificant to handle the temporary runoff, the excess runoff flowing through the 8"drain pipe that cannot be ducted away via the 6" drain pipe will be forced up through the catch basin louvers and down the drainage ditch until it reaches Via Ventana. In this mariner, there will never be a situation where excess water will run over the edge of the road into the neighbor's yard. I believe that the erosion and mud problem witnessed last winter has now been totally solved. The entire road has been base-rocked and with the above mentioned other drainage improvements, erosion should be a thing of the past. Particularly if the Town SEP-21-98 08 :55 AM JAY SHIDELER 650 941 5882 P. 02 1')2-z will allow me to pave a ten foot wide road with paver stones, latent erosion will not occur. The meeting we had with the staff last week went pretty well. It was my understanding that if the safety engineer approves the road proposal and if Barrie Coate writes a letter stating that paver stones will not adversely affect the 19"oak tree spaced 22 feet away on the neighbor's yard, then a permit will mostly be issued for me.to continue installing the paver stones. I am faxing to you the letter from Barrie Coate. Please inspect the drainage and paver stone application on the driveway and the upper easement road ASAP so that we can getour bond back.
