64. (MM 9.C.l) The developer's engineering staff and consultants should prepare recommendations and plans for preventing erosion and scour of natural creeks and existing drainageways. The method of creek protection should be chosen in consultation with the Alameda Flood Control District. Plans and recommendations should be provided for construction of concrete "v" ditches on all cut and fill slopes within the subdivision. The City should determine who should own and maintain the project site's creeks and drainage ways. They should not be owned or maintained by any individual homeowner. 65. (MM 9. C. 2) The approved erosion control plans and recommendations prepared by the developer'S staff and consultants should be installed as shown on the approved drawings. The developer'S engineers should provide continuous inspection during construction in order to ensure that the construction work is performed properly. 66. (MM 9.C.3) Planting and hydroseeding should be done to prevent surface (sheet) erosion. Effective erosion control provision should be installed as detailed by the Association of Bay Area Governments. In addition, good construction practices should be followed during grading operations to control wind and water erosion of excavated and exposed surfaces. 67. (MM 9.D.l) All fill placed for SUbdivision roadways and infrastructure should be placed in such a manner so as to minimize differential settlement. The developer's geotechnical and civil engineers should provide detailed recommendations and plans for acceptable cut and fill slope gradients, stripping, preparation of the subgrade to receive fill (inClUding keying, benching and construction of subsurface drains under fill placed on slopes), acceptable fill material, and fill placement requirements (inClUding method of placement and degree of fill compaction). Existing fill on the site which was not properly placed or compacted should be removed and replaced with engineered fill. All fill placed on site should be engineered fill, that is, fill placed in accordance with the recommendations of a geotechnical engineer. 68. (MM 9.D.2) The grading for the subdivision roadways and infrastructure should be performed as recommended by the geotechnical and civil engineers. The developer's engineers should provide continuous inspection when subdivision grading operations are being performed in order to ensure the grading work is being performed properly. 69. (MM 9.D.3) All fill placed during individual lot grading should be placed in such a manner as to minimize differential settlement. A subsurface investigation. by a geotechnical engineer should be performed on each lot before lot grading begins. The geotechnical engineer should provide detailed grading and foundation recommendations for each lot and house. The individual lot owner's geotechnical and civil engineer .
