Harris SUBJECT: Appeal of the Planning Commission's denial of Master Case 90.173 (Tentative Tract Map 49756 and Oak Tree Permit 90-037) to allow for the subdividing of three existing lots Into five single family residential lots for the properties located at 26862, 26864 and 26866 Sand Canyon Road. Applicant: Mr. Steve Parks, Mr. Roy Swank and Mr. Monty Fu DEPARTMENT: Community Development BACKGROUND On November 10, 1992, the City Council heard this Item and continued to It to a date uncertain. The Council directed the applicants to resolve drainage and safety issues associated with the project and that the re -designed project be returned to the Planning Commission for their review and comment prior to being heard again by the Council. On September 15, 1992, the Planning Commission adopted Resolution P92-34 denying Master Case 90-173. The project proposed a zone change from A-1-2 (Light Agriculture - two acre minimum lot size) to A-1-1 (Light Agriculture - one acre minimum lot size) to allow for the subdividing of three existing lots into five or six single family residential lots. Reasons for denial Included project drainage, failure of the project to meet requirements for street frontage on each lot, and safety Issues associated with the existing private driveway accessing the project. Prior to the Council meeting of November 10, 1992, the applicants revised the project requesting that only five lots be considered. This five lot project proposes to split both existing lots 1 and 2 with lot 3 -remaining Intact. The project no longer requires a zone change due to the City's adoption of the Unified Development Code (changing the zoning of the property to Residential Very Low, one dwelling unit per gross acre). PLANNING COMMISSION ACTION The project was heard by the Planning Commission on January 5, 1993. Prior to this hearing, the applicants submitted information attempting to resolve the Issues Identified by the Council. This information included a storm water containment plan and a driveway design plan. Below staff will summarize the proposed plans and Planning Commission comments. They are as follows: The storm water containment system, which proposes the construction of catch and containment basins on lots 2 and 4, would eliminate the Incremental Increase in storm water caused by the addition of two single family residences. However, this system would only slightly Improve the area's existing drainage situation. (The Commission did indicate that this proposal Is beneficial, as it eliminates the Increase In storm water caused by the additional two residences, but that It does not satisfy the Council's request to resolve the immediate area's existing drainage problem.) . APPROVED Agenda Item: • The driveway design plan shows three driveway schemes with each scheme showing a driveway width of 26', but at different grades. The existing Improved driveway width varies between 15 and 20 feet and has a maximum grade of 20% (the driveway area with the 20% slope Is located westerly of lot 1, within the flag strip accessing the development). Scheme 1 proposes to reduce the existing driveway grade from 20% to 17%. This scheme requires the construction of a retaining wall, with a maximum height of 10', along both sides of the driveway. Scheme 2 proposes to reduce the driveway grade from 20% to 15%. This scheme requires the construction of a retaining wall, with a maximum height of 15', along both sides of the driveway. The final scheme proposes to only widen the driveway to 26' In width, which requires a three foot retaining wall on the south side of the driveway. The applicants believe that the widening of the driveway to 26' to accommodate two-way traffic will eliminate the safety concerns associated with the driveway. The Commission, within Resolution P92-24, Indicated that the existing driveway grade is a safety concern. The Commission also Indicated that the other two schemes, while proposing to reduce the driveway grade, create a new safety hazard due to the height of the walls. Additionally, the Commission pointed out that the walls would create aesthetic Impacts. The Commission concluded that the trade offs were not beneficial with any of the attempts to make the access less substandard. As a result of the Commission's comments related to drainage, the applicants' engineer has submitted a conceptual off-site drainage plan. This plan is In addition to the two plans reviewed by the Planning Commission. This plan proposes a system that would carry a portion of storm water runoff from the project site across an adjacent property to the south with an outlet on the north side of Cachuma Lane. Staff has reviewed this plan and foresees the following problems with the system: • The system would be a continuing maintenance Issue, specifically related to who would assume maintenance responsibility of the system. • The system will not resolve the area's existing drainage problems as it only carries the storm water runoff further south to an undefined drainage course. Properties south of Cachuma Lane would not benefit from such a system. It is staff's opinion that this system does not satisfy the Council's request of resolving the area's existing drainage problems. This would not be grounds for denial of the subdivision since the California Subdivision Map Act does not require resolution of existing adjacent problems by a subdivider. The drainage solution was viewed by staff and Commissioners as a potential benefit to the neighborhood which might have been used to offset the substandard aspect of this application in regards to the access. OPTIONS The City Council may: 1) Uphold the Planning Commission's decision, denying Master Case 90-173; or 2) Approve Master Case 90.173, directing staff to prepare conditions and a resolution of approval for the Council's consideration. RECOMMENDATION The Planning Commission recommends that the City Council: 1) Deny Master Case 90-173 (Tentative Tract Map 49756 and Oak Tree Permit 90-037); and, 2) Direct staff to prepare a resolution of denial for the Council's consideration at the March 9, 1993 meeting. coundha9o•171gea ?U3L:" EAR.'IC ?ROCK:U?L: 1.

TRANSFER OF CHAIR Chairman Woodrow handed overthe chairmanship of the meeting to Vice -Chairman Doughman due to a problem with his voice. FLAG SALUTE Commissioner Cherrington led the Pledge of Allegiance to the flag. ROLL CALL The secretary called the roll. Those present were Chairman Woodrow, Vice-Chalrman Doughman and Commissioners Brathwafte, Charrington, and Modugno (who arrived at 7:03 p.m.). Also present were Lynn M. Harris, Director of Community Development; Richard Henderson, City Planner; Tim McOsker, Assistant City Attorney; Brad Therrien, Supervising Civil Engineer; Glenn Ademick, Assistant Planner; and Lucy Lancaster, Commission Secretary. CONTINUED PUBLIC HEARING ITEM 7: TENTATIVE TRACT MAP 49756, ZONE CHANGE 90-011, OAK TREE PERMIT 90-037 (MASTER CASE NO. 90.173) - Located at 26868, 26864 and 26666 Sand Canyon Road Mr. Henderson reported on this request to subdivide three existing lots Into five single-family residential lots. This hem wad denied by the Commission at the September 15,1992 meeting, and subsequently appealed to the City Council by the applicant. The City Council heard the Item on November 10, 1992, and directed the applicant to resolve drainage and access safety Issues associated with the project and that the revised project be returned to the Commission for their review and comment. Assistant Planner Glenn Adamitic presented the slides and staff report. Commissioner Brathwa@e reminded the Commission that when the project was brought before the Commission originally, the adjacent residents were opposed to Improvement on their properties. Chairman Woodrow inquired about the potentiality of Incremental rain Increase to the adjacent properties due to the subdivision. Mr. Brad Therrien, the City's Supervising Civil Engineer, stated_ that the present leach fields would accommodate the Incremental rain runoff. Acting Chairman Doughman opened the public hearing at 6:32 p.m.: Mr. Don Halo, Hale and Associates, 23922 Avenida Crescenta, Sams Clarita, CA. Mr. Hale spoke as engineer for the project and stated that It Is unrealistic for time City to believe that the applicant should bare the full responsibility for mitigating water runoff simply because he owns property on a hili. Mr. Stave Parks, applicant, 26884 Sand Canyon Road, Same Clarita, CA. Mr. Parks stated that he looks forward to reaching an agreement with the Planning Commission this evening so that the project can move forward. Ms. Diane Wilson, 26826 Sand Canyon Road, Santa Clarlte, CA. Ms. Wilson, speaking In opposition to the project, expressed her concerns of maintaining the rural standards of the Sand Canyon area, as well as concerns with the drainage and street Improvements. Ms. Marilyn Keehn, 26800 Sand Canyon Road, Santa Clartta, CA. Ms. Keehn, speaking In opposition to the project, supports the sentiments of the previous speaker, and Is also concerned with the drainage In particular as it Is her property the water flows directly onto. Mr. Don Hale gave a rebuttal to the concams raised. Acting Chairman Doughman closed the public hearing at 8:51 p.m.. Commissioner Brathwalto asked gtwstions regarding the applicant's willingness to meet with the nearby residents, and questions relating to drainage and leach field capacities. Chairman Woodrow asked whether an applicant Is responsible for fbdng previously existing problems. Mr. Henderson stated that the mitigation of preexisting problems are not always made a part of subdivision requirements. Commisalorm Modugno made comments on the driveway safety Issue and the flag lots. Commissioner Charrington commented that the engineer's testimony relating to the mitigation of the incremental rain runoff Is satisfactory to him. Commissloner Charrington added that the roadway Issue is safety versus aesthetica, and that the solution which provides for retaining walls creates a safety factor. The Planning Commisslon asked that staff report to the City Council that the positive does not outweigh the negative in the tradeoff. The Planning Commission concurred with Commissioner Cherrington's summarisation, and Included that they feel that this project should not be held responsible for correcting the pre-existing problem of water runoff. PUBLIC BUSINESS FROM THE FLOOR There was no one wishing to address the Commission. ADJOURNMENT At 9:55 P.M. Commissioner Brathwahe motioned, Commissioner Modugno seconded, and It was carried by a vote of 5-0, to adjourn the meeting to January 19, 1993.

Three existing single family lots exist on the project site. On September 15, 1992, the Planning Commission adopted Resolution P92-34 formally denying Master Case 90-173 (Zone Change 90.011, Tentative Tract Map 49756, and Oak Tree Permit 90-037). The project proposed a zone change from A-1-2 (Light Agriculture two acre minimum lot size) to A-1.1 (Light Agriculture - one acre minimum lot size) to allow for the subdividing of three existing lots Into five or six lots. Encroachment within the protected zone of oak trees was proposed due to widening of the access driveway. Reasons for denial Included drainage Issues, failure of .the project to meet frontage requirements, and safety Issues associated with the existing private driveway accessing the project. The applicants subsequently appealed the Commission's action to the City Council. The applicants, within the appeal letter, requested that the City Council only consider a five lot project. The Council heard the Item on November 10, 1992, directing the applicant to resolve drainage and safety Issues associated with the project and that the re -designed project be returned to the Planning Commission for their review and comment. At this meeting the Council stressed that resolving drainage issues Involves both the correction of the immediate area's existing drainage problems as well as showing that the addition of two single family homes to the project site will not compromise the corrective measures taken to fix the existing drainage problems. The Councll also required the applicants to submit a detailed driveway design which would resolve safety Issues associated with the grade of the existing driveway (portions of the driveway are at or near a grade of 20%) . The applicants have submitted Information attempting to resolve the Issues Identified by the Council. On December 24, 1992, the City's Unified Development Code and Zoning Map went into effect. This action resulted in the re -zoning of the project site to Residential Very Low (RVL - one dwelling unit per acre). The re -zoning of the project site eliminates the need for the zone change requested by the applicants. Agenda Items 7 I-) ANALYSIS: The applicants submitted both a storm water containment pian and a driveway design plan. Staff has reviewed both plans and has the following comments: 1) The proposed storm water containment system, as designed by the applicants' engineer, will eliminate the Incremental Increase in storm water runoff caused by the construction of the two new single family residences. The system proposes construction of catch and. containment basins on proposed lots 2 and 4. However, the proposed system will not alleviate any of the current drainage concerns Identified in the immediate area. In order to eliminate these concerns, off-site improvements would need to be constructed to define a water course which would eliminate the existing sheet flow of water across the properties to the south of the project site. 2) The driveway design plan shows three driveway schemes. Each scheme shows a driveway width of 26', but at different grades. The existing improved driveway width varies between 15 and 20 feet and a has maximum grade of 20% (the driveway area with a 20% grade is located westerly of lot 1 near Sand Canyon Road). Scheme 1 shows a reduction In the driveway grade from 20% to 17%. This reduction would require the construction of a retaining wall on both sides of the driveway. This wall would have a maximum height of 10'. Scheme 2 shows a reduction In the driveway grade from 20% to 15%. This reduction requires the construction of retaining walls with a maximum height of 15'. The final scheme shows the driveway at its existing grade, with widening, which requires a three foot high retaining wall adjacent to the driveway. The applicants believe that the widening of the driveway to 26' to accommodate two-way traffic will eliminate the safety concerns associated with the driveway and that any additional modifications are unnecessary. RECOMMENDATION: Staff recommends that the Planning Commission: 1) Receive. the new information related to the project; and, 2) Provide comments on the project and direct staff to forward these comments to the City Council for their consideration. pingcom149756.gea lei v ey CyN RD. • J �o'0 Vp FWY. 000 pig 4 N MANDAL" SUBJECT =717719 RD: i' SITE 111 3 l i Project Proximity Map r1 y. a .J ' ,1 llaa •� aaa' � O 7. / � . . 1- 2500, • v sa q , +7a 1 / i h • _ 1 •i.• 2Y.. t - -b y � 1 AGENDA REPORT City Manager Approval Item to be presented byy� �/— PUBLIC HEARING Lynn M.

Applicant: Mr. Steve Parks, Mr. Roy Swank, and Mr. Monty Fu DEPARTMENT: Community Development BACKGROUND On September 15, 1992, the Planning Commission adopted Resolution P92-34 formally denying the above referenced project. The project she fronts on Sand Canyon Road and contains three existing single family residences. The site is zoned A-1-2 (Light Agriculture • two acre minimum lot size). The applicants are requesting to change the zone from A-1.2 to A-1-1 (Light Agriculture • one acre minimum lot size) to allow for the subdividing of three existing lots, totaling 7.11 acres, Into six lots or five lots. The project site Is designated RVL (Residential Very Low, one dwelling unit per acre) by the City's General Plan. The project density Is consistent with this designation. The three existing lots each consist of approximately 2.3 acres. The project site has approximately 30' of frontage on Sand Canyon Road. The existing parcels were subdivided as flag lots, each having a 10' wide flag strip extending to Sand Canyon. An Ingress and egress easement was recorded over the 30' access strip for the tots served. This access strip Is paved (a minimum of 20' In width) and has a maximum slope of 200/c. A 20% slope Is the maximum slope allowed by the City's code for a driveway and Is considered sub -standard for a new subdivision. Approval of the project would necessitate the waiving of normally required "street frontage" for the proposed lots. The City's Code requires that each lot have a minimum of 50' of frontage on a street or right-of-way. PLANNING COMMISSION ACTION The project was heard by the Planning Commission on December 3, 1991 and September 1, 1992. At the first hearing, the Commission continued the Item to a date uncertain, directing the applicant to submit a five and six lot project. The Planning Commission considered both a five and six lot project at the September 1, 1992, meeting. Issues raised by the Planning Commission at this meeting were related to the following: 1) Project drainage - (Existing drainage patterns carry water to adjacent properties to the south. The Commission cited concern with the project worsening drainage conditions in the area.) S Master Case 90.173 Page 2 2) Frontage requirements - (The Commission cited the project's failure to meet minimum street frontage requirements, per the City's code. The use of a private driveway to access the development would not provide the minimum 50' of street frontage required by the City's code.) 3) Safety concerns - (Existing driveway grades on the project site exceed 15% and at one point Is 20%. The Commission Indicated that the existing private driveway, Improved to 26' In width, accessing any additional parcels would be unsatisfactory. The existing condition creates a safety hazard that could possibly worsen with the addition of any more single family homes.) A total of three persons spoke In opposition to the project. Staff did receive a total of three letters citing opposition to the project. All three letters were from an adjacent property owner. Following the last hearing on the project, the Commission voted 3-1 to deny the project (both the five and six lot design) due to the above identified Issues. The applicants, within the appeal letter, are now requesting that only the five lot project be considered by the City Council. OPTIONS The City Council may: 1) Uphold the Planning Commission's decision, denying the Master Case 90.173; 2) Approve Master Case 90-173, directing staff to prepare a conditions and a resolution of approval for the Council's consideration. RECOMMENDATION The Planning Commission recommends that the City Council: 1) Deny Master Case 90.173 (Zone Change 90-011, Tentative Tract Map 49756, and Oak Tree Permit 90-037), 2) Direct staff to prepare a resolution of denial for the Council's consideration at the November 24, 1992 meeting.

DENYING MASTER CASE NUMBER 90-173, ZONE CHANGE•90-011, TENTATIVE TRACT MAP NO. 49756, AND OAK TREE PERMIT 90-037. TO ALLOW FOR THE SUBDIVIDING OF THREE EXISTING LOTS INTO SIX SINGLE FAMILY RESIDENTIAL LOTS FOR THE PROPERTIES LOCATED AT 26862, 26864, 26866 SAND CANYON ROAD THE PLANNING COMMISSION OF THE CITY OF SANTA CLARITA DOES HEREBY RESOLVE AS FOLLOWS: SECTION 1. The Planning Commission does hereby make the following findings of fact: a. An application for a Zone Change (ZC 90-011), Tentative' Tract Map (TTM 49756), and an Oak Tree Permit (OTP 90-037) for six single-family lots was filed with the City of Santa Clarita by Roy and Marcia Swank, James and Nancy Denneny, and Monty and Wendy Fu (the •applicants•) on August 9, 1990. Staff was informed by letter on April 30, 1991, that Mr. and Mrs. Denneny were no longer applicants, .being replaced by Mr. and Mrs. Steve Parks. The properties for which this application has been filed are located at 26862, 26864, and 26866 Sand Canyon Road (Assessor Parcel Numbers 2841-019-051, 052, 053), legal descriptions of which are an file in the Department of Community Development. b. This project is a request for a zone change from A-1-2 (Light Agriculture Zone, two acre minimum lot size) to A-1-1 (Light Agriculture; one acre minimum lot size) to allow for the subdivision of three existing lots, totaling 7.11 acres, into six lots containing the following acreage: lot 1 - 1.60, lot 2 - 1.03, lot 3 - 1.09, lot 4 - 1.00, lot 5. - 1.00, and lot 6 - 1.07. The oak tree permit request is to allow for the encroachment within the protected zone of numerous oak trees due to the possible enlargement of an existing driveway accessing the project. d. The subject parcel is designated Residential Very Low (RVL, 0:50 1.00 dwelling units per acre, no midpoint density). The proposed density for the project is approximately .86 units per acre. e. The project site contains three existing single family -residences. The project site is moderately sloped, but does contain hillside areas with slopes in excess of 40x. Existing drainage patterns carry water to adjacent properties to the south. The property was previously subdivided into three single family lots by Parcel Map 8252. The project site has 30' of frontage an Sand Canyon Road. The existing parcels each meet minimum street frontage requirements for flag lots (10'). An ingress and egress easement was recorded over the 30' access strips for the existing lots. The paved portion of the project's existing access varies.. from 20' to 30' in width. A portion of the access strip has a slope of 20Z for approximately 150', which is the maximum allowable slope. pursuant to the City's Zoning Code. RESO P92-34 Page 2 f. The project site lies adjacent to Tract 47785, which contains lots averaging one acre in size. To the south and east lie single family residential lots ranging in size from one to three acres. To the west is Sand Canyon Road. g. The existing residences are each serviced. by a private septic system. The applicant is proposing to service the additional residences with septic systems. h. The applicants are requesting. the removal of the existing flag strip access, replacing it with a private driveway design. This design will require the creation of easements over the access, to service the six lots. This design requires the waiving of the normally required street frontage for the six lots. i. The City of Santa Clarity General Plan contains several goals and policies related to the sensitivity and compatibility of new residential development to existing residential neighborhoods and restricting development where natural hazards are present. These policies include, but are not limited to, Land Use Policies 6.2, and 7.3. J. This project was reviewed pursuant to the provisions of the California Environmental Quality Act (CEQA). k. A duly noticed public hearing was held by the Planning Commission on December 3, 1991 at 7:00 P.N. at the City Council Chambers, 23920 Valencia Boulevard, Santa Clarita. At this public hearing, the Planning Commission voted 3-2 to continue the item to a date uncertain, directing the applicants to resolve issues associated with the project (drainage and non-compliance with the City's Zoning Code) and return to the Commission with both a five and six lot design for the Commission's review and consideration. At this meeting the applicant and applicant's engineer verbally agreed to suspend processing timelines for the project. This was followed up by a letter dated December 4, 1991, from the applicant's engineer agreeing to the suspension of processing timelines. 1. On June 3, 1992, the applicant submitted the revised six lot map. On August 23, 1992, the applicant submitted the revised five lot map. M. A duly noticed public hearing was held by the Planning Commission on September 1, 1992 at 7:00 P.N. at the City Council Chambers, 23920 Valencia Boulevard, Santa Clarita. SECTION 2. Based upon the above findings of fact, oral and written testimony and other evidence received at the public hearing held for the project, and upon studies and investigations made by the Planning Commission and on its behalf, the Planning Commission further finds as follows: a. At the hearings of December 3, 1991 and September 1, 1992, the Planning Commission considered the staff reports prepared for this project and received testimony on this proposal. Testimony from surrounding property owners included concerns that the project would worsen existing drainage problems• and that the project would negatively impact the rural qualities of Sand Canyon. RESO P92-34 Page 3 b. The City's General Plan designation for the project site is Residential Very Low (RVL). The project (six or five lot design) is inconsistent with previously referenced Goals and Policies of the City's General Plan due to the possible worsening of existing drainage conditions and access constraints. The site zoning is A-1-2. C. Pursuant to the State of California Subdivision Kap Act Section 66474, the project (six or five lot design) substantiates the following finding for denial of a tentative map: That th site +s not nhvsicall suitable for the ronose� density of dewelonma,t. (A private.driveway, improved to 26' Ln width, accessing six residential parcels is not satisfactory. Driveway grades exceeding 15Z exist on-site and would not be reduced in conjunction with the project. This condition creates safety concerns that could possibly worsen with the addition of any more single family residences on the project site. Additionally, the project does not complywith City Code Sections 21.24.290 and 21.24.300 which: require a minimum of 50' of frontage at the right-of-vay line. Approving this project necessitates the waiving of the street frontage requirements. Also, Lot 5 on the six -lot proposal lacks easily discernible front, rear, and .side yards due to site constraints associated with the existing homes.) d. Pursuant to Code Section 22.16:150, the project (six or five lot design) fails to substantiate, to the satisfaction of the Planning Commission, the folloving required finding: change of zone . from A-1-2 to A-1- (The th the project, fails to substantiate this i requirement. Concerns cited previously related to access, drainage, and the waiving of frontage requirements are not in conformance with good zoning practice and are not in the interest of public health, safety and general welfare.) SECTION 3. Based upon the foregoing facts and findings, the Planning Commission hereby determines as follows: a• The project (five or six lot design) is not consistent with the City's General Plan. b• The project (five or six lot design) substantiates a finding associated with denying a tract map. C. The project (five or six lot design) fails to substantiate the findings required by Code Section 22.16.150 related to recommending approval of a zone change. . PESO P92-34 Page 4 NOV. THEREFORE, BE IT RESOLVED by the Planning Commission of the City of Santa Clarita, California, as follows: The'Planning Commission hereby denies Master Case 90-173 (Zone Change 90-011, Tentative Tract Map 49756, and Oak Tree Permit 90-037) to allow .for a zone change from A-1-2 to A-1-1 to subdivide three existing lots, totaling 7.11 acres, into six single family residential lots.

Chairman Woodrow opened the public hearing at 7:21 p.m. Speaking for the applicant was the project engineer, Mr. Keith Uselding of Hale and Associates, 26017 Huntington Lane, Unit B, Valencia. Mr. Uselding discussed the project's design, oak tree preservation, the addition of fire hydrants to the neighboring properties, and the attempt at retaining the rural atmosphere of the area. Mr. Don Hale, also of Hale and Associates discussed the drainage issue and their proposed drainage plan. Mr. Roy Swank, 26866 Sand Canyon Road, Santa Clarita, discussed the project history, the costs of the project, the lot configuration, and requested approval of the 6 lot design. If the 6 tot design was not acceptable, he would request that the 5 lot design be approved. Speaking in opposition were the following: Diane Wilson, 26826 Sand Canyon Road, Canyon Country, commented on her concerns regarding drainage onto her property, retaining the rural atmosphere of Sand Canyon, and the safety of. horses. Mr. James Webb, 26826 Sand Canyon Road, Canyon Country, also had concerns regarding drainage. Mr. Webb showed several slides showing erosion and water run off onto his property. Marilyn Keehn, 26800 Sand Canyon Road, Canyon Country, expressed concerns regarding drainage, and would like to seethe 2 acre zoning remain. Mr. Don Hale was then given the opportunity for rebuttal. Mr. Hale stated that the project is within the density shown in the General Plan, and that the engineers have been working with Public Works on innovative drainage solutions. There were then questions of the applicant. At 7:46 p.m., Chairman Woodrow closed the public hearing. Discussion ensued among the Commission Commissioner Modugno motioned to deny the project.

CITY OF SANTA CLARITA STAFF REPORT Zone Change 90-011 Tentative Tract Map 49756 Oak -Tree Permit 90-037 DATE: September 1, 1992 TO: Chairman Woodrow and Members of the Planning Commission yLQ cf` FROM: Lynn M. Harris, Director of Community Development����� PROJECT PLANNER: Glenn Adamick, Assistant Planner II APPLICANTS: Mr. Roy Swank, Mr. Monty Fu, Mr. Steve Parks a LOCATION: 26866 Sand Canyon Road, Sand Canyon area, (Assessor Parcel Numbers 2841-019-051, 52, 53) REQUEST: A zone change from A-1-2 (Light Agriculture Zone, 2 acre minimum lot size) to A-1-1 (Light Agriculture Zone, 1 acre minimum lot size). to allow for the subdivision of three existing lots, totaling 7.11 acres, into six lots containing the following acreage: lot 1 - 1.60, lot 2 - 1.03, lot 3 - 1.09, lot 4 - 1.00, lot 5 - 1.00, and lot 6 - 1.07. Additionally, an oak tree permit is requested because the existing private roadway may be altered. This driveway encroaches into the protected zone of numerous oak trees. BACKGROUND: On December 3, 1991, the Planning Commission voted 3-2 to continue this item to a date uncertain, directing the applicants to resolve issues associated with the project and to return with both a five and six lot design. Issues raised by the Commission included the project's non-compliance with the City's Zoning Code (due to the creating .of a lot that does not contain the required area) and project drainage, the last being identified by a surrounding neighbor as a concern. Additionally, the Commission directed staff to provide information related to the project's consistency with the proposed Sand Canyon Special Standards. The three existing lots each consist of approximately 2.3. -acres. The subdivision requires a change in the existing zoning of "Light Agriculture, 2 acre minimum lot size" (A-1-2) to "Light Agriculture, 1 acre minimum lot size^ (A-1-1). The density of the proposed development is approximately .86 dwelling units per acre, which is within the density range for the Residential Very Low land use designation of the City's it IR General Plan. The project site has approximately 30' of frontage on Sand Canyon Road. The existing parcels were originally subdivided as flag lots, each having a 10' flag extending to Sand Canyon Road. An ingress and egress easement was recorded over the 30' access strip for the lots served. The access strip decreases in width to 20' at a point after the first residence's driveway. The access strip is improved (a minimum of 20' in width) throughout the project and has a maximum slope of 20Z. The applicants are not proposing to remove any of the eleven (11) oak trees on the project site nor is any encroachment planned with the individual driveways or future residences. Possible encroachment may occur if enlargement of the primaryprivatedriveway is necessary. This encroachment is not anticipated to be significant. The existing residences are each presently serviced by a private septic system. The applicant is requesting the removal of the flag strip access, replacing it with a private driveway. This will require the creation of the proper easements (ingress and egress, utility) over the access, to service the six proposed lots. These easements would be shown on the final map. An approval of this configuration would waive the normally required "street frontage" for the proposed lots. ANALYSIS: The applicants have submitted revised maps with project densities of both six and five lots. The five lot design excludes existing lot 3 (the rear lot), subdividing existing lots 1 and 2 into two additional lots. The five lot design (proposed lots 1, 2, 3, 4, and existing lot 3) eliminates. proposed lot 5, a lot which staff cites a concern with and will detail in its review of the six lot design. Additionally, the applicant has relocated the .pad area on lot 4 from its previous location (located directly adjacent to the northern property line) southerly, adjacent to the private driveway servicing the project. This relocation eliminates the need of an ingress and egress easement across property lines to access the pad for lot 4 and eliminates a previous staff concern related to the lots meeting minimum area requirements for the A-1-1 zone. Staff ,favors this design,. believing the site is physically suitable for a density of five lots. The six lot design implements the pad relocation on lot 4 and adds proposed lot 5. Staff still maintains a concern with the configuration of proposed lot 5. The lot lacks easily discernible front, rear, and side yards. Additionally, the lot is similar in design to a flag lot, but does exceed the minimum lot width requirement of 501. The six lot design also requires the use of a shared driveway to.access lots 5 and 6. This shared driveway would be utilized on a small portion of the lot and would not reduce the net square footage of lot 5 below the minimum 40,000. -2- Staff has also compared the project with the proposed Special Standards for Sand Canyon.. The project appears to be in conformance with a majority of the standards, excluding the requirement to extend public sewer to subdivisions containing more than four lots. A public sewer line is located approximately 5,000 feet to the north, at the intersection of Live Oak Springs Canyon Road and Sand Canyon Road. The applicant has received clearance from the Health Department to service each lot with a private on-site sewage disposal system. Staff believes the proposed access (private driveway - 26' in width) is satisfactory to accommodate the. development, is consistent with the proposed Special Standards, and could be supported by goals and policies of the City's General Plan related to maintaining the rural qualities of Sand Canyon. An adjacent property owner cited a concern related to existing drainage problems and the possible negative impacts that may occur with the additional development of three residences. This property is located, directly to the south and is approximately five feet lower than •the lowest part of the project site. Staff has received a preliminary drainage concept in conjunction with the project, and the concept has been approved by the Engineering Division. The Engineering Division indicated that the addition of three single family residences would produce no significant increases in runoff from the site, nor change existing natural flow patterns of the immediate area. Additionally, landscaping added in conjunction with residences may reduce future runoff. As proposed,staff still has concerns with the project density of six lot's. These concerns, which are associated with lot 5, 'include its configuration, similarity to a flag lot, and the use of a shared access driveway. Due to these concerns, staff believes the project fails to substantiate all of the findings associated with approving a tract map, specifically the finding related to the site not being physically suitable for the proposed density of six lots. RECOMMENDATION: Staff recommends that the Planning Commission: 1) Re -open the Public Hearing; and 2) Conceptually approve the five lot design; and 3) Continue the item to the October 6, 1992 Commission meeting, directing staff to return to this meeting with a resolution and conditions approving Tentative Tract Map 49756 (five lots) and -Oak Tree Permit 90-037 and recommending approval of Zone Change 90-011 to the City Council.

Harris, Director of Community Development Glenn Adamick, Assistant Planner II Mr. Roy Swank, Mr. Monty Fu, Mr. Steve Parks 26866 Sand Canyon Road, Sand Canyon area, (Assessor Parcel Numbers 2841-019-051, 52, 53) A zone change from A-1-2 (Light Agriculture Zone, 2 acre minimum lot size)` to A-1-1 (Light Agriculture Zone, 1 acre minimum lot size) to allow for the subdivision of three existing lots, totaling 7.11 acres, into six lots containing the following acreage: lot 1 - .1.60, lot 2 - 1.03, lot 3 - 1.06, lot 4 - 1.04, lot 5 - 1.04, and lot 6 - 1.15. In addition, an oak tree permit is requested because the existing private roadway may be altered. This driveway encroaches into the protected zone of numerous oak trees. PROJECT DESCRIPTION: The applicant is proposing to subdivide the subject three parcels into six parcels. Existing on-site are three lots and three single family residences. The existing lots each consist of approximately 2.3 acres. The subdivision requires a change in the existing zoning of "Light Agriculture, 2 acre minimum lot size, (A-1-2) to "Light Agriculture, 1 acre minimum lot size• (A-1-1). The project site has approximately 30' of frontage on Sand Canyon Road. The existing parcels were originally subdivided as flag lots, each having a 10' flag extending to Sand.Canyon Road. An. ingress and egress easement was recorded over the 30' access strip for the lots served. The access strip decreases in width to 20' at a point after the first residence's driveway. The access strip is improved (20' in width) throughout the project and has a maximum slope of 20Z. The applicant is not proposing to. remove any of the eleven (11) oak trees on the project site nor is any encroachment planned with the individual driveways or future residences. Enlargement of the primary private driveway would result in additional encroachment though it would not be significant. The existing residences are each presently serviced by a private septic system. The applicant is requesting the removal of .the flag strip access, replacing it with a private driveway. This will require the creation of the proper easements (ingress and egress, utility) over the access, to service the six proposed lots. These easements would be shown on the final map. An approval of this configuration would waive the normally required "street frontage" for the proposed lots. SURROUNDING LAND USE/ZONING/GENERAL PLAN CONSISTENCY: As proposed, this zone change and subdivision request for residential development would result in a density of 0.86 dwelling units per acre. This is consistent with the City's General Plan designation of Residential Very Low Density (RVL) (0.5 to 1.0 dwelling units per acre). All proposed lots exceed one .acre in size. The existing zoning, the City's General Plan designations and the existing land uses of the project site and adjacent properties are as follows: ENVIRONMENTAL REVIEW: As part of the project review, an environmental assessment was made to evaluate the impacts of the project. It was. determined that this proposal would have no adverse environmental impacts which could not be avoided through project design and mitigation measures. Subsequently, a draft mitigated Negative Declaration was prepared for this project. INTERDEPARTMENT/INTERAGENCY REVIEW: The project has been distributed to the affected City departments and agencies, and the Community Development Department has received requirements and comments from.the following: �s. -2- City 's General Plan Zone Land Use Project Site RVL (Residential A-1-2 Residential Very Low) North RVL (Residential A-1-1 Vacant, Tract Very Low) 47785 East RVL (Residential A-1-1 Residential Very Low) South RVL (Residential A-1-1 Residential Very Low) Vest RE (Residential A-1-2 Residential Estate) ENVIRONMENTAL REVIEW: As part of the project review, an environmental assessment was made to evaluate the impacts of the project. It was. determined that this proposal would have no adverse environmental impacts which could not be avoided through project design and mitigation measures. Subsequently, a draft mitigated Negative Declaration was prepared for this project. INTERDEPARTMENT/INTERAGENCY REVIEW: The project has been distributed to the affected City departments and agencies, and the Community Development Department has received requirements and comments from.the following: �s. -2- 14 The Engineering/Traffic Division recommends that the applicant: 1) Install a left turn lane for south -bound traffic on Sand Canyon to the project, 2) Participate on a °fair share" basis for improvements from the project site to Soledad Canyon Road with the associated bridge widening over the Santa Clara River and Highway 14, 3) Provide the appropriate sight distance for the project driveway intersection with Sand Canyon road. The Parks ,and Recreation Department recommends that the applicant provide a 15' wide multi -use trail easement to be located adjacent to Sand Canyon Road. The Engineering Division recommends that the applicant offer a portion of right-of-way (52' from centerline), on the project's frontage, as outlined by County Survey Book 3030-1 and the City's General Plan. ANALYSIS: The proposed residential subdivision would not alter any present land uses in the area, as the surrounding uses are residential. The private driveway design would include a driveway width ranging from a minimum of 26' to 301, with 26' being improved (paved) to allow for two-way traffic. A turn around, to the satisfaction of the Fire Department, would be implemented at the terminus of the driveway. The Engineering Division is indicating that this design is satisfactory to accommodate the subdivision. proposal, with the inclusion of a condition requiring the applicant to provide documentation illustrating the use of an easement _ for utilities, ingress and egress. In addition, an agreement for maintenance of this common driveway and easements should be required. The surrounding properties all have satisfactory access available to them and the requirement that this proposal provide a dedicated street would not be necessary. In addition, the requirement of a full right-of-way (60' in width) and improvements would necessitate extensive grading, -oak tree removals, and the purchase of off-site property. Staff believes this private design is'satisfactory based on the above and the following: 1) The project design allows for one point of access off of Sand Canyon Road. The Traffic Division is encouraging proposals to be limited to one point of access off a major highway. Goal 1, Policy 1.10, of the Circulation Element, as summarized, states: Limit the number of intersections and driveways on all major roadways to promote a safe, efficient and. steady flow of traffic. The subdivision proposal utilizes one access point off of Sand Canyon Road to service the project. 2) The utilization of the private drive in place of a fully improved .and dedicated street could be found consistent with the rural character of Sand Canyon. Goal 3, Policy 3.12, of the Land Use Element could further support this: Maintain and enhance the desirable rural qualities found in the certain existing neighborhoods which are rural in character, such as Placerita, Sand, and Hasley Canyons. -3- The density of the proposed development is approximately .86 dwelling units per acre. The City's adopted General Plan indicates. that all lots should have a full acre gross, and 40,000 square feet net, in this category. As shown on the submitted map, the net square footage of each lot exceeds 40,000 (gross square footage minus the access driveway and utility easement), though the net square footage of, proposed lot 3 is not accurate due to the inclusion of the square footage contained within the driveway accessing proposed lot 4. This driveway extends through proposed lot 3 and would require the establishment of an easement. The easement square footage would be subtracted from the existing net square footage of proposed lot 3 and could possibly reduce the net below 40,000 square feet. The project lies adjacent to recently approved Tract 47785 which utilized an average lot size of one acre. To the south of the proposal, are one acre lots utilizing a private driveway and flag lot design. Generally, the proposed lot sizes would be consistent with the surrounding lots, though the configuration of the lots would be inconsistent. The project would not be required to pay any QUIMBY fees, due to the size of the proposed lots exceeding one acre. The applicant has indicated a willingness to contribute a fair dollar amount comparable to QUIMBY fees for the proposal, if a six lot subdivision were to be approved. If QUIMBY fees applied to this project, the fee would be approximately $3.500. This contribution by the applicant would be to the Parks Department for the improvement or installation of park facilities in the Canyon Country area. There are a total of 11 oak trees on the project site. The. proposed enlargement of the existing 20' wide access to 26' in paved width would cause additional encroachment into the protected zone of the affected oak trees adjacent to Sand Canyon Road, though no removals would be necessary. The applicant has submitted an oak tree permit for encroachment. Staff believes that the proposed conditioning of the applicant to submit a driveway design (to the satisfaction of the Director) illustrating this enlargement and its effects on the trees could be satisfactory. Permeable materials and the specific placing of the re -designed driveway, within the existing 30' strip (where it is adjacent to Sand Canyon Road); could be implemented to reduce the existing impacts and possible future impacts upon the affected oak trees. Staff does have concerns relating to the configuration of proposed lot 5. Lot 5 as proposed lacks easily discernible front,rear, and side yards. The applicant has indicated that lot 5 is configured in this manner due to constraints imposed by topography and the existing single family residences located on-site. Staff also has previously cited a concern with the access drive proposed through lot 3 to lot 4. The locating of the pad area of proposed lot 4 closer to or adjacent to the 26' wide private driveway would eliminate the necessity of this driveway. The applicant has indicated that the location of the pad area on lot 4 is due to the existing flat terrain at that portion of the proposed parcel. -4- 11 Pursuant to Santa Clarita Municipal Code Section 22.16.150, in making its recommendation relative to a proposed zone change, the Commission shall consider five principles and standards. Staff believes the project. as proposed, fails to substantiate one of the five findings as follows: Finding Number 4 requires that the proposed zone at such location will �- in the interest of public health, safety and general we and in conformity. with good zoning practice. Staff believes the change of zone, in conjunction with the six -lot proposal, does not satisfy this finding. The concerns illustrated above with proposed parcels 4 and 5 are in conflict with this finding and specifically with good zoning practice. In addition, staff believes the site is not physically suited for the development of six lots. RECOMMENDATION: Staff recommends that the Planning Commission: 1) Open the Public Nearing; and 2) Direct the applicant to re -design the project density to five lots and conceptually approve this design; and 2) Continue the item to a date uncertain, with the understanding that the project timelines will be suspended while the applicant prepares a re -designed project for evaluation. by staff. Upon submittal of a satisfactory re -designed project, staff will return to the Planning Commission with a resolution and conditions approving 'Tentative Tract Map 49756 and Oak Tree Permit 90-037 and recommending approval of Zone Change 90-011 to the City Council.

This design consists of a curb along the south side of the existing private driveway to intercept the surface flows and an onsite catch basin. The catch basin would collect water and carry -south to Cachumma Lane in an underground 12" corrugated metal pipe. The installation of an inverted catch basin/energy dissipater at Cachuma Lane would ensure that the water would exit the pipe without the kinetic energy of a concentrated flow. We have discussed this concept with the property owner to the south (Ms. Wilson). We would need .their offsite approval to install this system. Please review the enclosed concept and contact me to discuss this proposal. Thank you for your continued cooperation and assistance in this matter. Sincerely, D. E. HALE R. C. E. Encl. cc.

Also transmitted herewith are exhibits showing the location of the S.W.R.C.P, components, the special details required to contain the stormwater, a section showing the percolation basin construction, and details proposed for reducing the grade .of the existing driveway. (proposed private street). PROJECT PARAMETERS & OBJECTIVES: Tentative Tract Number 49756proposes a five lot subdivision with three existing single family residences situated on a hillside east of Sand Canyon Road between Cachuma Lane and Mandalay.Road. The natural drainage pattern directs storm water down hill to the south and west, towards the Sand Canyon wash. The current problem exists south of Lot 2 where structures have been constructed in the channel bottom. Currently, during a rainfall event, these structures are inundated by flood water. In an effort to improve the existing conditions and prevent any incremental increase in runoff as a* result of the two new proposed buildings, we propose the following: Design 'a retention system that would contain the runoff from the impervious surfaces of the new structures.. This system would store the runoff underground in percolation basins that would recharge the groundwater in the area. This is an additional benefit to an area that depends on wells for their water supply. The stormwater containment plan would also consist of the planting of native plant species within the relatively barren slopes of Lots 4 and 5. These of antz tr_' 11 sloe: the flow of :nater an -:-:courage Percolation. The plants will also reduce the amount of silt which flows during storms which will assist in minimizing sheet flow volumes. 19 STORMWATER RUNOFF CONTAINMENT CALCULATIONS (Modified from 10/29/92` letter): DETERMINE THE ROOF AREA FOR A 3500 S.F.

DEPTH): 5250/6 = 875 S.F PLAN DIMENSIONS: 20 X 44 CONCLUSION: The stormwater containment plan will control the impact of the incremental increase in runoff from the proposed new construction. This will not only allow for "no increase" in existing flood water, but it should result in a "decrease" inasmuch as the imperious materials will drain 100% to the storage/ recharge basins below grade. Diversion walls would be employed to assure that the areas to be drained are not contaminated with silt from surrounding run off areas.

For reference, my property is approximately 3/4 of a mile north of the project site, just south of Valley Ranch Road. The planned project should -have no significant effect.on the existing oak trees. Additionally, improvements to the roadways and water system are anticipated. This project will provide additional housing sites, which I believe will help to stimulate the local ecomony, while creating an acceptable residential density for the area.

I have several objections to the zone change and I am in agreement with the Planning Commission's Denial of this project. Please consider the following factors and vote against the appeal by the applicants: 1. The.City Development Code has designated a Special Standards District in our area whose purpose is to maintain, preserve and enhance the rural and equestrian character of Sand Canyon. This proposed zone change increases density and alters the rural character of the area. 2. Most current residents surrounding this property are on larger parcels (2+ acres). Most of us have animals. If you continue to approve zone changes, our animals will gradually disappear. Increased density brings in a different type of homeowner and soon our horses, goats, chickens, etc. will be unwelcome. We strongly object to that change in our community. 3. The proposed street configuration and lot division does not follow good planning practices. Existing residences make the lot split awkward. Flag lots are undesirable. 4. Although they do not state an intention to remove oak trees, there is a heritage oak adjacent to the access road.

The application is Zone Change 90-011, Tentative Tract Map 49756 and Oak Tree Permit 90-037. We object to the zone change on the ground that the addition of, three residences at the above location will alter the exist- ing natural drainage of water and cause water, mud and other debris to flow upon and under Cachuma Lane, cross it and eventu- ally end up on Sand Canyon. This will create an unnecessary Civil Liability of the City. Existing development along Sand Canyon has already resulted in .road flooding and blockage. Although grading is not proposed at this time, it is ludicrous to believe that the addition of three residences with landscap- ing will not alter the existing natural flow and create potential damage or injury. In the event you grant the application, the City of Santa Clarita and the proponents are hereby placed on notice that the element of "lack of notice" will not be a defense to any future civil liability arising out of the above project. /.

I have several objections to this project. I want to retain the rural flavor of the canyon and strongly support the SPECIAL STANDARDS DISTRICT created by the, spirit of our community. We love animals, open space, oak trees, and low density. We object to cutting up everyone's acreage to create more lots. Higher densities are appropriate in other areas of our fine city; please preserve the variety of choices available to homebuyers by keeping Sand Canyon rural. Growth will occur naturally as people build out to the current zoning. All zone changes should be carefully reviewed according to the parameters set by the General Plan and the Special Standards District. This zone change request will have a negative effect on the equestrian atmosphere. Currently, horses, goats, sheep, chickens, cats and dogs live at peace in our canyon. Shrinking lot size will bring in people who are not animal -oriented. Eventually animals will be squeezed out. Two of the proposed lots are immediately adjacent to our barn and arena. Will the proposed homeowners like our five horses? We have three acres - our five horses and two dogs don't bother anyone. This project endangers their lifestyle. I have seen what zone changes. did in my parent's neighborhood and horses are no longer welcome. I want to protect the current zoning; I want Sand Canyon to remain rural. The Planning Commission rejected this project for several reasons. Part of their decision was based on the land plan. Due to the existing residences, the street access and lot configuration is awkward. The site is hilly and not conducive to proper planning, given the current home locations. Use of flag lot design is not desirable. My final point concerns drainage. We already receive substantial runoff from the three existing residences. Adding more concrete and roof square footage decreases the absorption of storm water. All of the neighbors to the south of the site are concerned about drainage. This problem will not be minor. We presented slides to the Planning Commission to indicate the current situation and those photographs clearly indicated that more homes would exacerbate the problem unless mitigated by an elaborate drain system. 3a I am a concerned neighbor and an active homeowner in the equestrian community of Sand Canyon. The local homeowners have regularly met to review the various projects going into our area. We have discussed in great detail what standards we want for our community. We all moved into Sand Canyon because of the -Oak Trees, the open space, the lack of street lights and sidewalks, and the atmosphere where animals are welcome. Please help us keep that choice open to future generations. Please deny this zone change. Thank Youl Sincerely, Diane C.

I have several objections to the zone change and 1 am in agreement with the Planning Commission's Denial of this project. I would be negatively impacted by this proposal and feel it is detrimental to the character of our neighborhood. I want to retain a rural atmosphere where animals are welcome and the density is low. After attending several Special Standards meetings, it is clear that Sand Canyon residents are in agreement on that subject. We know that our animals will only be welcome if the lots are large; animals are much more appropriate on two acres than one. Please keep our two acre zoning. In addition, the design of the subdivision is awkward because the site is not flat and the three existing residences are in the way of usual lot line configurations. The flag lots and an atypical access road will have a detrimental effect on our immediate neighborhood and negatively impact the property values. Finally, the increased density exacerbates the current drainage flow across our barn area. The addition of three additional home roofs and concrete areas will decrease the absorption of- storm water and will cause increased flooding for all of the neighbors to the south of the site. Any subdivision, if approved, should be required to mitigate this problem. 1 hope that you will uphold the decision of the Planning Commission.

The tentative map was denied by the Planning Commission by a split vote. on September 1, 1992.• The existing drainage condltions.at this site were a controversial issue at'the;Planning:;Ccimaission hearing, yet no one from .the City's ;Englneering Department . was present to address the drainage.issue::=By;thtsletter I am requesting your presence at the -City Counci.lthearing:In order to have you address the drainage; issue:,;, The City had required the submittal of a drainage; concept;. for this project at the early stages of thedesign:.=The drainage concept was submitted and approved. Assistant Planner Glenn Adamlck and Assistant Engineers Chris Price and Curtis Nay are.famillar with the project and the drainage issue. The following is offered to assist you in the background for this project. As you are aware, by City Ordinance, new construction may not increase drainage and drainage runoff onto adjacent Properties. However, drainage calculations for runoff areas within Los Angeles County have Incorporated conservative design parameters to account for future construction. Therefore, existing drainage facilities should be sufficient for future bulldout construction as well as for existing construction. The exception is that this protection is not valid for existing nonpermitted, unprotected structures occuring In flood plalns and those nonpermltted structures which were constructed prior to the Los Angeles County Building Ordinance. It has never been proven that new construction results In an Increase in drainage runoff. It is assumed that there will be additional runoff simply due to the fact that some of the natural hillside will be covered with Impervious materials. ^, However. It is already assumed that the soll.ls saturated in the calculations for capital floods and no consideration is given to percolation. Therefore, the Imperviousness of the new construction Is irrelevant in the design of capital floods. Imperviousness of building materials may play a part in slight increases In storm water runoff for storms of a lesser magnitude than the fifty year storm. But what is the problem If all projects are to be designed for the fifty year storm? A twenty five year storm with a one percent Increase in runoff should be much less of an Impact than the runoff from the designed event (50 year storm). A good argument can be made for the fact that additional retention is provided In graded pads with on site planting and landscaping. This additional retention may compensate for any additional imperviousness resulting from building construction and/or hardscape. Landscaping on a building pad will most definately Increase the time of concentration and therefore reduce the peak of the storm runoff hydrograph: Nevertheless,"for-areas_such.as Acton,..Los�AngeIes.County has required'the implementatibn "of basln" 0 reduce peak flows -(or to maintain existing dralnage-.,flows) for projects where.new construction is proposed.,i:These storage areas have been added as a precautlon:to insure that existing (calculated) peak flows are not -,exceeded.. It is the belief of Los Angeles.County Staff that the'oaontribution of "additional runoff" which they would attribute' ='to`new- construction would be controlled by these•"Delta Go :basins. - However, they will admit that the water diverted into these basins will not actually reduce the peak flow Inasmuch as it Is taken from the first stream flows of the storm runoff and not from the stream flows at maximum flowrate. Delta 0 basins are objectionable from a standpoint of being an attractive nuisance for children. They are ugly, fenced depressions which attract mosquitos and other unwanted Insects. They emit odors. They require maintenance for Perpetuity. They are unpopular with neighbors wherever they are Installed. There is a concern in the area of the subject project that existing stormwater runoff may be detrimental to nearby property owners. Testimony was given at the Planning Commission hearing that barns and utility buildings (constructed in the floodway) downstream of the project site are flooded each time It rains. The applicants offered a solution to this drainage Issue (as described below). We ask you to review the following proposal and discuss any concerns with us that may come to mind. Furthermore, we ask that you Cor one of your staff) be present to comment on the merits of the following proposed solution. Provide roof gutters at all roofs of.all future structures and conduct all rainwater runoff through the patio. Our report of that Inspection, dated June 27, 1991 (copy attached), once again Identified the drainage problem. Three mitigating measures were Proposed to minimize the contributory drainage onto the patio. A fourth mitigating measure was proposed to preclude "standing water" on the deck, whether the source was drainage from the parking deck or deposited directly onto the patio via rainwater. The crack In the stucco does not appear to represent a structural failure. However, It should of the anticipated rainfall volume.on the Impervious structure during the capital storm.

I own a three acre parcel which I purchased with the intent of raising and riding my Arabian horses in a rural atmosphere. I purchased this property based on low-density zoning in the area. I vehemently object to changing the zoning and the character of the area. There is plenty of density elsewhere in the City. Sand Canyon is intended to have Special Standards which the majority of residents want. Cutting up existing lots so that current owners may sell off a portion of their estate is short- sighted from a planning standpoint and the only justification seems to be greed on the part of those existing owners. The proposed subdivision is awkward. Two of the proposed new lots would be difficult to sell at any price in today's oversupplied real estate market. ,The result does not seem to justify applying for this subdivision. Regardless, I am negatively impacted by their proposal. This subdivision would alter the rural character of my neighborhood by surrounding my equestrian arena with three additional residences. Of major importance is the negative impact of storm water drainage from these three new residences. We currently receive a torrent of storm water through our barn/arena area from the three existing homes. We invited the staff planner to visit the area during the winter rains and .took slides to show that there is, indeed, a negative impact which must be brought to the attention of the Planning Commission. The storm water races through our property, undermines Cachuma Lane as it moves south, and creates a lake on our neighbor's barn area. Any new residential construction will make this bad situation worse. If you approve this subdivision, I would demand that the property owners devise a new storm drain system using sump pumps in order to take their storm water down their access road rather than across our land. 39 There are many other issues important to me as a resident of Sand Canyon. I am worried about the large oak tree which will be damaged if the access road is widened.. I am worried about the lack of infrastructure to support the ever-increasing density in the canyon. Last years rains required periodic closure of Sand Canyon Road due to the inadequate storm drain system. Our neighborhood children do not have a safe walkway along Sand Canyon :Road - additional traffic increases the hazard.' Finally, I hope you rememberthatmost homeowners who have purchased property in Sand Canyon did so because they wanted open space, quality of life conducive to animals, large lots and oak trees. Please deny this proposed zone change and sudivision as it violates the character of the.area.and contributes to the increased density which most homeowners oppose. Thank you.

Wilson 26826 Sand Canyon Road Santa Clarita, CA 91351 I live immediately adjacent to the proposed zone change and subdivision at 26828-26866 Sand Canyon Road. We own a three acre parcel and we strenuously object to changing the zoning to one acre in our'area. We want to retain our rural atmospherewhere animals are welcome and the density is low. The proposed subdivision is poorly designed due to the fact that the three existing residences are in the way of usual lot. line configurations. This requires an awkward street and land plan. This erodes property values and alters the character of the area. This increased density exacerbates the current drainage flow across our property. During the rainy season we have a river, going through our barn and arena area and it undermines Cachuma Lane as it moves southward. If you were to approve this proposal, I would insist that they alleviate the potential damage from storm water by installing a new drainage system. This drainage' system must include sump pumps capable of taking the storm water up their street and down into Sand Canyon. I hope you deny this request for a zone change. Thank you. Sincerely,. Diane C. Wilson 0 To: Planning Commission City of Santa Clarita From: Diane Wilson/ James Webb 1991: 26826 Sand C anyon Road, Santa Clarita 91351 ;i.'• t Re: Zone Change 90-011; Tentative Tract Map #49756 As an immediate neighbor of this proposed project, we are disappointed in the re -zoning of theareainto smaller lots. This project as well as the Cloyd development (Tentative -Tract #47785) have de-emphasized the rural/equestrian flavor of our neighborhood. Our three acre horse property is gradually becoming an anomaly in the area. It appears that we will also be forced to subdivide as larger equestrian properties will eventually not be the "highest and best use" of the land. We cannot stop progress but we do hope all of -the oak trees will be preserved and horse trail access will be protected. Our major concern about this project is the drainage onto our riding arena and barn area. Currently, all three of the existing residences drain onto our property. The Fu's property drains into our barn area and two inches of water stands during the rainy seasons (even under the drought conditions of the past four years). The Swank and Parks' properties drain into our arena creating a river which goes across the arena southward toward Cachuma Lane and the barn area of the lowest property in the area which is adjacent to our site. The run-off from roofs and paved areas of these three proposed new residential lots will have to be channeled and diverted elsewhere or our entire equestrian area will be under water. The soil does not absorb water or drain well so this is of major concern to us. The mitigation of this problem needs to be a condition of this project. VyM-1 MM*Z 11 43 E HALE & ASSOCIATES, Inc.

This design consists of a curb- along. the south side of the existing private driveway to intercept the surface flows and an onsite catch basin. The catch basin would collect .water and carry south to Cachumma Lane in an underground 12" corrugated metal pipe. The installation of an inverted catch basin/energy dissipater at Cachuma Lane would ensure that the water .would exit the pipe without the kinetic energy of a concentrated flow. We have discussed this concept with the property owner to the south (Ms. Wilson). We would need their offsite -approval to install this system. Please review the enclosed concept and contact me to discuss this proposal. Thank you for your continued cooperation and -assistance in this matter. Encl. cc.

Our project was originally heard by the Council in November. At that meeting the Council directed us to analyze specific issues and have the Planning Commission review the project again. We went to the Planning Commission on January 5, 1993. We would like to request a two-week continuance to allow us time to continue to work towards a compromise solution with our neighbors. We participated in a meeting with our nearest neighbor, Mr. James Webb, on Monday, February 15, 1993. During this meeting at the project site, Mr. Webb indicated that additional neighbors would like to be included in the discussion. We would like: some additional time to meet with Mr. Webb's neighbors. Please convey our request for the proposed extension to the City Council. We understand that you cannot grant the extension and that the request must be made to the Council. We will be present to make our request to the Council at the scheduled meeting on February 23, 1993. Thank you for your cooperation in this matter.

Stephen Parks 26864 Sand Canyon Canyon Country, CA 91351 February 13, 1993 The Honorable Jan Heidt Members of'the City Council City of Santa Clarita 23920 Valencia Blvd. Suite 300 Santa Clarita, CA 91355 My dear Mayor Heidt and members of the City Council: g � � 0') 4GMMUOf SSA Gm I am a homeowner in Sand Canyon adjacent to the site which was designated as Master Case 90-173, denied by the Planning Commission and appealed to the City Council. As this case comes before you again for final consideration, I ask that you uphold the decision of the Planning Commission and reject the appeal. Over a dozen letters have been submitted by nearby homeowners for the past six months opposing this subdivision for a number of reasons. Residents on Sand Canyon, Cachuma Lane, Millmeadow Lane and Iron Canyon have raised several issues. I hope that you will review those letters in the public file. My main concerns have been cited both in correspondence and at the city meetings. I agree with staff and Planning Commission members who have denied this project because it does not meet the standards set by the subdivision code in several major ways: 1. The lots do not have adequate frontage on a street - they are flag lots accessed by a private driveway. 2. The driveway access is unsafe and substandard. The steep 20% slope up from Sand Canyon can be altered only by building unsightly retaining walls. The driveway design does not follow good planning guidelines for safety. 3. The drainage from the two new lots exacerbates an already existing problem of erosion and flooding across at least 4 properties located south of this project. The most recent solution proposed by the engineer attempts to resolve the problem on our property and would further concentrate the water onto the other properties. Water does not flow down Cachuma Lane, rather it sheets across the lower properties to the south. The rains this winter have emphasized how much damage flooding can cause. New driveways and homes will add to the runoff. The solution presented by Hale & Associates does not solve the anticipated drainage damage on the four properties to the South. They have failed to provide a system that will meet the needs of the neighborhood. The engineers continued to promise that they could design a satisfactory drainage plan and they have yet to fulfill that promise. In closing, I would like to ask the City Council to deny this appeal and accept the recommendation of the Planning Commission and City Staff. The standards for creating a subdivision must not be compromised on the significant issues of safety, drainageterosion control, and street design without serious consideration. Thank you.
