Livick, P.E.—Su a ising Civil Engineer SUB_ JECT: FINAL ACCEPTANCE OF PUBLIC IMPROVEMENTS FOR TRACT 2307,A 154-LOT RESIDENTIAL SUBDIVISION AT 11855 LOS OSOS VALLEY ROAD [DEVAUL RANCH, LLC AKA SLO ESTATES INC, FRANCISCAN DEVELOPMENT SUBDIVIDER] CAO RECOMMENDATION Adopt resolution (Attachment 1) accepting the public improvements and releasing the bonds for Tract 2307 (Vicinity Map, Attachment 2). DISCUSSION The required subdivision improvements approved with the tentative map, per Resolution No. 8975 (1999 Series) approved October 19, 1999, have been completed to City standards and specifications. The subdivider has requested acceptance'of the public improvements by the City and release of the respective sureties. Public improvements include approximately a 0.93 acre park, 5,500 linear feet of new public streets (including Spooner Drive, Eto Circle, Welsh and Foreman Courts and portions of De Vaul Ranch and Tonini Drives), water, sewer, storm drain and typical utility company mains and services. The final map for Tract 2307 was approved, per Resolution No. 9224 (2001 Series), on September 1, 2001. Included with the final map approval was a subdivision agreement that allowed the Subdivision Labor and Materials and the Faithful Performance bonds to be released "upon City Council acceptance of the subdivision improvements and upon receipt of a guarantee for ten percent of the cost of the public improvements. The cost of the public improvements was estimated to be$4,494,677. The subdivider has provided a surety bond in the amount of$449,468. This guarantee is to insure that the subdivider will remedy any defects in the improvements arising from faulty workmanship or materials or defective construction of said improvements occurring within twelve (12) months after subdivision acceptance, in accordance with City Council Resolution 9313 (2002 Series) and Sections 66499.7 and 66499.9 of the Government Code of the State of California. Remaining Issues The subdivider has proposed that the following two known issues be resolved during the 12 month warrantee period: . Privately Maintained Detention Basin The detention basin located adjacent to Madonna Road near the center of Tract 2307 is generally functioning as anticipated. The basin temporarily detains storm water runoff as mitigation for the (a--4 Final Acceptance of Tract 2307 Page 2 development of the site. The basin also captures and retains sediments, which improves the water quality of the overall tributary area. Nuisance flows are accommodated by a perimeter drainage system comprised of an 8 inch PVC pipe extending to the outflow weir structure. This basin and associated site improvements is privately owned and maintained.by the Homeowners Association (HOA), although the City has easement rights for use of the basin area for recreation purposes (see Lot 151 in Figure 1). 77 ------ !! r /.sy •nr�r` i Al eacrmc 16— , P III I I 11 ��' Catty +�,.I'•, I St A � � CItaPHk 9[uP /�%', 1W 111 P Qm A Q 1.5W o a- _ 0 ii .•' �-—_ �.1i iJi--=--' it aG ..�.. .� 9 . ....,...:..�•o..,., 1 Ito Is It LU W N W r', ,, W II st°.rli Z ff 14:v I i3-' to II 11I I N W ill W I �+ i ttR uD IV it 81. ;II '•- it ; Ftl II ..ter..��.� Y'u t o �J8 �o y' Qit � fi �y'M..r•"r�� •, �'��r'.s.w.s' � ,m��m.®®ELL � w TRACT No. 2307 vaar..mamrnne.rrruw.aam.a yl � a �.•R m waacvrawcnwmwasA:sanw.a. t !

This uncharacteristically high annual rainfall caused a large amount of sediment and eucalyptus debris to be carried from the Irish Hills towards the underground storm, drain systems adjacent to the historic farmhouse. The sediment runoff was enough to cause a partial clogging of the perimeter drainage system, and fill the concrete aprons at the discharge points of the HDPE pipes with sediment. The saturated conditions have made sediment removal from the basin difficult. Once the basin dries, the sediments will be removed and perimeter drainage system in the basin will be cleaned. Much of this maintenance work will be required by the HOA after each rainy season in order to maintain a functioning detention system. Traffic Circle The traffic circle at Eto Circle and Madonna Road still remains a problem with the directional signs being hit and drivers continuing to drive over the center paver area and the edge of the landscaped area. The subdivider has requested that additional "maintenance" improvements, to Final Acceptance of_Tract_2307 the already constructed traffic circle, be deferred to the warrantee period so that Public Works and Fire Department staff can re-evaluate the approved design and work with the subdivider, Home Owners Association and the subdivider'.s engineer to resolve the problem. CONCURRENCES Both the Utilities.and Community Development Directors concur with the recommended action of accepting the public improvements. FISCAL IMPACT Typical maintenance and operation of public facilities will be required for park, street, stormdrain, sidewalk, sewer and water infrastructure. The cost for maintenance and operation of the sewer and water facilities will be, offset by the monthly service charges. The costs for street maintenance and other non-enterprise fund items such as park services, fire protection and police protection are general fund costs.
