ITEMS ADDED DUE TO GREEN INFRASTRUCTURE
Storage Stone $298,500 $30/CY (Creekwalk bid) ‐ Assume $35 for a 17% contingency $ 200,970
Additional Trees/Shrubs
Additional Trees/Shrubs $101 840 Bioretention removed from projects, deduct shrub costs from green.

Adequate root volume for trees was a comment from City on original
Silva Cell $97,458 design prior to Silva Cell pilot. Green share of silva cells assumed at 75% $ 106,310
and share of tree costs assumed to be 50%.
ITEMS MODIFIED AS A RESULT OF GREEN INFRASTRUCTURE
8" Asphalt to 8" Porous Concrete (Parking Lane) $63,350 Unit Cost difference too high. Replace with $10/sq. ft.
g p q $ 21,240
Green infrastructure does not require grass areas to be converted to
porous pavers. Therefore, a 50% cost share ($116,250) would appear
Regular Pavers/Top Soil & Seed to Porous Pavers $172,350 more reasonable $ 95,046
Please clarify the assumption for 39% of total traffic control being
Work Zone Traffic Control $56,629 allocated to green. The City indicated that as work preceded block to
block that traffic could be detoured around the block in progress $ 66,806
