TSS removaiBMP's for treatment and detention of stormwater proposed for development of this <br />Property may inc|ude, but shall not be limited to traditional BMP's such as detention ponda, grass - <br />lined avma|ee, rain gonjeno, bioowa|eo, biofiltration ponds and native drought -tolerant plants for <br />landscaping ornon-tnaditiono|.innovative BKAP'o. The technical design oftraditional BK8P'wshall ba <br />inaccordance with the City ofSan Marcos Storm Water Technical Manual. The use nfinnovative or <br />non-traditional BMP's shall be approved by the City and used within the Property when accompanied <br />by supporting documentation (i.e. product research / testing or acceptance from other jurisdictions) <br />illustrating the effectiveness of the ByNP'o in achieving treatment standards identified herein. The <br />technical design of innovative or non-traditional BK8P'm ehoU be in accordance with supplied <br />supporting documentation. Approved vegetative buffers and filters shall not include invasive species. <br />Low Impact Development (LID) techniques allow for greater development potential with |eem <br />environmental impacts through the use of smarter designs and advanced technologies that achieve <br />m better balance between ooneervotinn, gnowdh, ecosystem pro1eotion, public health, and quality of <br />life. VVhora feasible and practical to achieve maximum water quality otondardo, the development <br />within the Property may incorporate various LID tenhniqueo, in one form or another, that work in <br />conjunction with traditional BYNP'stoachieve 8596TSS removal. <br />Development of the Property may incorporate pervious paving materials such as pervious pavers, <br />pervious concrete (grasscrete or ecocrete) or other pervious paving materials where appropriate. For <br />pervious paving materials used, technical documentation demonstrating the pervious nature of the <br />specific system or systems as installed shall be provided and approved by the City. |nthe event that <br />City approved pervious paving materials are utilized, the development of the Property shall receive <br />credit towards the Permitted Maximum Allowable Impervious Cover. <br />During the construction pnomaya, stabilization and protection measures shall be utilized to limit site <br />disturbance tothe construction perimeter (the limits ofconotructiun). The type and adequacy ofthe <br />erosion and sedimentation controls shall be subject to approval of the Director of Development <br />Sen/imsa prior to installation. All erosion and sedimentation controls ehoU be monitored and <br />maintained cdall times during the construction process. Acombination ofvarious approved erosion <br />and sedimentation control measures will beimplemented where appropriate. <br />Discharge of sediment from the construction site shall be minimized and controlled as per applicable <br />City, State and Federal requirements. It shall be the responsibility of the Owner and its contractors to <br />clean upany discharge ofsedimentation from the Property. No construction ahe|| begin until all <br />required City Plans are approved and a stormwater pollution prevention plan (SWPPP) is produced <br />bythe Owner and approved bythe City. Anerosion and sedimentation control program shall include <br />construction sequencing and sedimentation/erosion oonbn| measures to be implemented during <br />construction. The type and adequacy of the erosion and sedimentation controls shall be subject to <br />City approval prior to installation. All erosion and sedimentation controls nhoU be monitored and <br />maintained at all times during the construction promaae, and shall be inspected on an appropriate <br />frequency, as specified in the SWPPP, and results shall be available for inspection by the City at all <br />times. <br />AfuU Water Pollution Abatement Plan (VVH4P) including a geologic assessment and geotechnical <br />repod, prepared by licensed third -party engineer and/or professional geologist selected by the <br />Owner and approved by the City of San Marcos Director of Engineering and Capital Improvements, <br />nhoU be provided by the Owner and approved by the City, prior to the approval of any final plat on <br />the Property or any portion thereof. The WPAP documents shall include construction sequencing and <br />detailed means and methods for drainage and sedimentation/erosion control measures to be <br />implemented during construction. The type and adequacy ofthe erosion and sedimentation controls <br />shall besubject toCity approval prior boinstallation. All erosion and sedimentation controls shall be <br />monitored and maintained at all times during the construction process, and shall be inspected on an <br />appropriate frequency (as specified in the approved WPAP) by a qualified, third -party engineering <br />inspector, and results shall be provided to the City following each inspection. <br />12 <br />3493291.1 <br />
