The tentative map ind Gated grading for the roadway within the project and two lot Subsequently, the developer has submitted grading plans for the subdivision showing a greater amount of grading than had bee shown on the approved tentative map. This report is to inf rm Council of the extent of change. It is my REC h MENDATION: That Council approve the resolution relative to the grading concept shown on the grading plan. BOA D/COI+IMISSION RECOMMENDATION: The revised grading was rev ewed by the Environmental Review Committee on November 12, 198 A public hearing was not conducted at this meeting. The Com ittee made the following findings and recommendations: 1. The proposed changes are not significant and it is not necessary for the Environmental Review Committee to hold a public hearing on these revisions. 2. That City Council find that the changes proposed will not involve ne w significant environmental impacts and will not require important revisions to the EIR. DIS USSION: The proposed grading as shown on the Tentative Map and described in he EIR for Peppertree Estates, CVT 81-7 is different than indicated on the grading plans submitted by the developer on Sep ember 29, 1981. Ori finally, the plan for this project indicated grading for roa ways and for Lots 14 and 15. Quantities relative to grading sta ed in the EIR were: Cut 4800 cubic yards Fill 7300 cubic yards Import 2500 cubic yards Page 2, Item ~> Meeting Date 12-22-81 The EIR also indicated that five custom homes would be con tructed with grading for those homes. The Tentative Map did not indicate this grading because the extent of grading was un k own . Gra ing plans submitted by the developer indicate grading of each lot to provide pads for future home construction. Areas of nat ral topography would be maintained, especially along Jac randa Drive. Access drives, drainage facilities, utilities and the first five dwelling units would be installed. Volume of gra ing compares as follows: EIR NEW PLAN Cut 4800 7,560 cubic yards Fill 7300 19,200 cubic yards Imported 2500 12,100 cubic yards Ret fining walls would also be installed. They would not be sta dard block walls but rather a system of block which would per it landscaping along its face and easy reconstruction as find vidual lots are built out. The walls would be 5 to 6 feet in hei ht. Split level units (1-4 ft.) are proposed, as well as two story homes. This is a deviation from the one story and split level hom s tailored for each individual lot as originally envisioned. A p imary issue relative to the extent of grading on this site is the retention of mature trees. A breakdown of the trees to be removed and retained relative to the grading as now proposed is as ollows: a. ~ Total number of existing trees 154 b. Number of trees to be removed 1. On hots 1-14 30 2. In street right-of-way 21 3. Total number of trees to be removed 51 c. Number of trees which are dead, declining or insignificant (which are part of the 51) 10 d. Number of trees to be preserved 103 e. Percentage of healthy, significant trees to be removed 26.6$ ~~ /~~33 '~. Page 3, Item 22 Meeting Date 12=x-81 Replacement of all trees removed will be under the direction of the City's Landscape Architect. Alt ough the work shown on the grading plan is different from tha shown on the Tentative Map, the long term condition should be ess obtrusive under this proposal. All lots will eventually be graded on an individual basis if not done no w. We consider a single grading, landscaping, and irrigation plan preferrable to individual development. An overall grading plan will provide for con ise drainage facilities as well as uniform landscaping and irr gation. In addition, replacement of trees removed by the gra ing operation would be completed under one plan thus pro iding continuity and asssurance that the trees will be rep aced . Fiv of the lots will have houses constructed on them by the dev loper. This will provide continuity between the arc itectural design of at least five homes. An ~nalysis of the environmental issues as outlined in a memo to the Environmental Review Committee is attached. Adj~cent property o wners have been notified relative to pla ement of this item on Council's agenda. Sli~es of the Tentative Map and grading plans with slopes and pad delineated are available for Council viewing. FISCAL IMPACT: Not applicable.

Members of the Environmental Review Committee ~ gym: Dou las D. Reid, Environmental Review Coordinato r 9 bject: EIR-81-2 Pepper Tree Estates Background 1. When environmental review for a project has been completed, no 'urther analysis is necessary unless "Subsequent changes are proposed in .he project which will require important revisions of the EIR...due to the nvolvement of new significant environmental impacts..." When significant project revisions (substantial and adverse) are proposed :he Environmental Review Committee is to hold a public hearing to determine f additional review is required. 2. In this case the applicant is proposing project revisions which could significant in nature. The relevent sections of the EIR are as follows: a. It is anticipated that initial construction would create five custom 11homes, with subsequent development consisting of individual lot preparation and house construction for future homebuyers under developer control." Page 11 b. "Project concept plans propose one story and split-level custom homes, individually designed for each lot. Natural landform and existing trees will be retained to the greatest extent possible in order to preserve the existing natural aesthetics of the .parcel. In order to preserve the physical character of the property, land preparation, such as clearing and grading, will be delayed until individual homesite construction is ready to begin. Upon commence- ment, grading operations will be kept to a minimum to promote erosion control and reduce construction noise impacts to adjacent properties." Page 14 c. The construction phase of the project is expected to consist of a "period of initial grading and land preparation, construction of five homes, and then sporadic building of custom homes as the remaining lots are sold." page 18 d. TF~e proposed plan for the Pepper Tree project will moderately alter "the present topography. Lots 14 and 15, which are located in the canyon, will require cut-and-fill grading to produce building pads at the base of the southern slopes of the canyon. The grading involved ~ ~ -, ,~ `~' ,5~ ...,.~ . EC E R-81-2 , 2 with these lots will cover 0.6 acres total. This alteration will involve maximum cut depths of 6 feet and fill depths of 14 feet, with maximum cut slopes of 9 feet (with 2:1 slopes) and maximum fill slopes of 12 feet (with 2:1 slopes). Quantities of material involved are as follows: Cut 4800 cubic yards Fill 7300 cubic yards Imported 2500 cubic yards Presently, no other grading is planned for the other lots in the project. About 1.8 acres of the Pepper Tree property will involve grading for street construction. The development of the remaining lots will cause some slight alteration to the present topography; however, this alteration will be minimal due to the mostly level existing topography and tailored desiggn treatment for each home's placement on individual lots.~~ Page 59 Project Revisions 1. Initially the project was to consist of grading for the installation of blic improvements and utilities and the development of five custom homes. bsequent development would be on a lot-by-lot basis under the control of the bdivider. 2. The developer now proposes to grade each lot in order to provide a pad or future construction. Areas of natural topography would be maintained, especially long Jacaranda Drive. Access drives, drainage facilities, utilities and the first five darelling units would be installed with the first phase. Volume of rading compares as follows: EIR New Plan Cut 4800 7,560 cubic yards Fill 7300 19,280 cubic yards Imported 2500 12,100 cubic yards Retaining walls would also be installed. They would not be standard block alls but rather a system of block which tivould permit landscaping along its face nd easy reconstruction as individual lots are built out. The walls would be ypically 5', but up to 6' in height. One of the lots proposed for development at this time is ~9 which involves he reconstruction of a portion of this retaining wall. (Details will be shown t the Environmental Review Committee meeting.) Split level units (1-4 ft.) are proposed, as well as t~vo story homes. This s a deviation from the one story and split level homes tailored for each individual of as originally envisioned. 3.

The new plan shows substantial fill at the rear of 1 is 8 - 12. The natural topography across these lots drop by about 12' to 30'+ f om the front to the rear property line. Lots 9, 10, and 11 are proposed to be s lit level pads with the reconstructable retaining wall at the top of a slope bank n ar the rear of the lots. It would seem likely that development of these lots o an individual basis would require, because of the topography extensive foundations, r taining walls or fill slopes, No development plans for these lots have been vailable until this time. 4.
