The tentative map indicated that roughly 12,000 cubic yards of soil would need to be imported to grade the site. The maximum height of fill would be approximately 5 feet. Carlsberg Tract 4974, immediately to the east of the subject site, has dedicated property to the Ventura County Water Works District for the construction of a water tank site. Grading on the water tank site will produce an excess of roughly 18,000 cubic yards of soil that needs to be exported in late March On March 3rd, 1997 the City received a request from Marketplace Properties that they be allowed to receive and stockpile the soil that will be exported from the water tank site (letter attached). As of this date no grading plan has been received for the Marketplace site but the applicant has submitted a proposed stockpile plan (attached). Discussion Marketplace Properties has indicated that it is their plan to go forward with developing the KinderCare portion of the site as soon as a contract is signed. The start of construction date, however, is uncertain. Due to the immediate availability of the soil it is the applicant's desire to receive and stockpile the soil until the grading plan is approved, at which time it will be spread and graded per the approved plan. As such, the applicant has requested that they be allowed to temporarily stockpile the soil for an indefinite period (see revised request letter dated March 7, 1997). The applicant's engineer has stated that he is currently working on the grading plan for the site and that it should be submitted to the City for review shortly. He has also reevaluated the preliminary grading estimate and feels that the development will be able to utilize all 18,000 cubic yards on site due to anticipated shrinkage of the compacted soil. The proposed location of the stockpile will be the southerly portion of the Marketplace site, to a maximum height of approximately 10 feet with positive drainage to the southeast. Sandbags are proposed to control erosion. The existing drainage basin at the southeast corner of the site is shown to be left undisturbed. The truck haul route proposed by the Water Works District will be Peach Hill Road to Spring Road. Direct access from the Carlsberg site is apparently not possible due to the saturated condition of the site. It is proposed that hauling of soil commence late March and should take 2 weeks. Between 1200 and 1800 truck trips will be necessary. Grading plan check fees and inspection deposits will be required based on the yardage of soil imported. A surety is also typically required for such work, based on cost, should the city have to remove the soil or finish the grading if the developer, for any reason, is unable to. Staff would also suggest that, as part of the temporary stockpile permit, the applicant remove the existing slab and chimney on the site. The estimated cost to remove and export the stockpile, remove the chimney and slab, repair the fence and clean up or repair city property, if necessary is estimated to be $95,000 plus a 10% contingency. However, the developer has requested that they only be required to bond for the spreading of the soil - not for import/export and that all sureties be released immediately upon completion of the stockpile. Excluding the cost of import /export would reduce the estimate to $38,000 plus a 10% contingency. It is the applicant's contention that there will be no need to export the soil because the site will need this much earth for future development, even if he is unable to finish grading and the property is developed by someone else. OV(mV2 It is staff's opinion that the stockpile, as proposed, is visibly too high and abrupt and, if left uncompacted, unstable to leave indefinitely. If vegetation doesn't take, sandbags deteriorate, fill slopes collapse, etc. site drainage also may be adversely impacted. A more appropriate stock pile plan might be one that more closely reflects grading as shown on the tentative map, is less visibly obtrusive and is more stable. It is recommended the following conditions be attached to the issuance of a temporary stockpile permit: Special Conditions • Applicant shall submit a surety equal to $95,000 plus 10% contingency for import operations (10% of which is to be retained until such time that final grading and compaction of the site is approved by the City). In addition to all import /export operations, surety shall also cover the repair and maintenance of a 6 foot high fence in good condition around the perimeter of the property. • Maximum height of the temporary stockpile shall not exceed 5 feet. • Fill slopes shall not exceed 4:1. • Stockpile area shall be sandbagged and seeded for erosion control. • Weekday truck traffic on Peach Hill Road shall be limited to the hours of 9:15 a.m - 3:00 p.m • All streets shall be cleaned daily or as requested by the City Engineer. The existing drainage channel shall be protected and unobstructed. • The existing slab and chimney shall be removed from the site prior to the import of soil Summary Due to the immediate availability of soil from the Carlsberg site and the need for soil at the Marketplace Properties site, the applicant is requesting that they be allowed to import and stockpile 18,000 yards of soil for an indefinite period. This soil is proposed to be used for site development by the applicant after a grading plan is approved. The applicant anticipates that construction may commence within the year. Standard grading plan check fees and inspection deposits will be required for the import and stockpile. The applicant, however, requests that he not be required to provide surety for the cost of exporting /importing soil. He also requests that all sureties be released upon completion of the stockpile. Staff feels that a less abrupt stockpile than the one proposed, one more reflective of the approved tentative map, should be placed and that a full surety for all work, including import /export costs, and a reduced surety for maintenance should be provided Recommendation: Authorize staff to issue a temporary stockpile grading permit for the import of 18,000 yards of soil at the Marketplace Properties site, for an indefinite period of time, subject to all standard plan check and inspection fees and each of the special conditions discussed. 000029 Marketplace Properties Real Estate Developmer,' 13522 Newport Avenu( 2 Tustin, CA 92780 (714) 731-8888 FAX (71-4) 7W 7,525 March 7, 1997 Mr. Dirk Lovett City Engineer City of Moorpark 799 Moorpark Road Moorpark, CA 93021.
