YEARSEXPERIENCE 31 EDUCATION M.S., Civil/Structural B.S., Civil Engineering LICENSES Professional Engineer: CA #C40947 Leadership in Energy and Environmental Design (LEED) Accredited Professional YEARSEXPERIENCE 30 EDUCATION M.S., Civil Engineering B.S., Civil Engineering LICENSES Professional Engineer: CA #C37141 Urbanization, occurring in areas such as the Santa Clara Valley, reduces the ability of rainfall to be infiltrated into the soil which contributes to the degradation of stormwater quality and to creek erosion. The reduction in the ability of soil to infiltrate and retain stormwater is caused by many factors including, but not limited to the: 2

5 SANTA CLARA VALLEY URBAN RUNOFF POLLUTION PREVENTION PROGRAM DESIGN, REVIEW AND/OR CERTIFY STORM WATER TREATMENT MEASURES AND HYDROMODIFICATION CONTROL FACILITIES Removal of existing vegetation; Installation of buildings and covered areas; Use of impervious pavement surfaces; and Collection of stormwater directly from impervious surfaces to discharge to an offsite stormwater conveyance (i.e. pipes). The requirements of the Municipal Regional Stormwater NPDES Permit (MRP) are intended to reduce the impacts of future urbanization on the county s creeks and downstream water bodies, such as San Francisco Bay and the Pacific Ocean. During project design, the reduction in impacts is derived from a multi-pronged approach; including site design, source control, treatment, and hydromodification management, where necessary. To comply with the MRP, project designers must incorporate physical elements, such as reduced impervious surfaces, or consider other project alternatives. Flexibility as to how the project achieves compliance is in the designers control. Depending upon the project site, there are some potential constraints to various means of compliance within Santa Clara County. Some issues may include available space, depth to groundwater, and the ability of soils to infiltrate at an acceptable rate, cost, and keeping abreast of the regulations themselves. First, much of the valley is well developed. Many sites are small infill areas which have little available space after the required improvements have been laid out. One way to avoid this issue is to consider site design with the MRP in mind. Site layout, site grading, and opportunities for LID are important components to consider early in the design process. Designers may also investigate options beyond the minimum standards while ensuring sound engineering design principles when incorporating LID elements. Second, the MRP designates minimum depth to groundwater to reduce the potential groundwater contamination resulting from stormwater. In some parts of the County, the groundwater table is close to the surface, precluding the use of infiltration. The rate of infiltration of the site soils can also preclude the use of onsite stormwater retention. Much of the Santa Clara Valley is composed of clay soils, which have low infiltration rates. Both of these issues may be barriers to the use of infiltration or to the design of biotreatment elements. Third, the cost of LID and biotreatment measures can also be an issue. Project budgets often have little flexibility. The use of significant portions of the budget for stormwater infiltration or treatment can be unpopular. For example, pervious pavement and the water quality volume storage beneath it often cost more than traditional pavement. However, one must also consider the overall life cycle cost and the costs of alternative or off-site compliance. Costs must be coordinated and discussed among project team members to select site-appropriate, budget-friendly solutions. Low impact, sustainable solutions tend to provide benefits beyond compliance with regulations. Finally, there are updates to the MRP and the methods of compliance. Some examples of these updates include green roof specifications, biotreatment soil specifications, and implementation dates. To ensure compliance and prevent the need for significant redesign of projects, one must be aware of these changes. One way to keep abreast of changes is to attend training workshops or webinars. It is critical a project s design complies with the permit appropriately. For example, in the past, biotreatment was a primary means of compliance. However, under the MRP, POTENTIALISSUES Available Space Groundwater Depth Soil Infiltration Rate Cost Regulatory Updates 3

6 SANTA CLARA VALLEY URBAN RUNOFF POLLUTION PREVENTION PROGRAM DESIGN, REVIEW AND/OR CERTIFY STORM WATER TREATMENT MEASURES AND HYDROMODIFICATION CONTROL FACILITIES biotreatment (or bioretention) may only be considered after rainwater harvesting and use, infiltration, and evapotranspiration have been deemed infeasible for a project site. In addition, uniform specifications and guidelines are available for LID options such as green roofs and bioretention soils. SCVURPPP s C.3 Stormwater Handbook is an appropriate reference for selection and design of available means of compliance. In some areas of the County, degradation of unlined channels is a concern. The degradation is caused by higher volume of runoff, longer runoff times, and higher creek velocities. Hydromodification Management (HM) controls are necessary to reduce impacts to the creek for projects adding specified amounts of impervious area, in locations designated on the mapping provided in the C.3 Stormwater Handbook. The impacts of development on runoff from a range of storms must be assessed using continuous simulation modeling, such as the Bay Area Hydrology Model (BAHM). The results of this analysis necessitate additional measures beyond those related to stormwater quality. One example is to provide a basin to retain and to meter flows from the site. Issues associated with the incorporation of a basin, whether above or below grade, include: space, other potential uses for the basin, and the outlet diameters. HM controls tend to result in small diameter outflow pipes, which can become maintenance intensive. These outflow pipe diameters may be adjusted after discussion with local agencies, so communication is a key element of their design. Compliance must also be documented and confirmed for each project. The above considerations might not be presented on a set of project construction documents. Therefore, a form of clear, careful documentation will communicate this information to a reviewer. In addition, it may be necessary to provide this documentation to a representative of the Regional Board who is verifying MRP compliance for selected projects. Clear and complete documentation will save staff time and will provide agency staff with confidence that projects within their locality comply. Healthy water bodies benefit residents, users and wildlife. Managing the impacts of urbanization can help create healthier water bodies. HMM understands that continuous hydrologic simulation provides advantages for understanding the potential impacts of hydromodification. The timing of storm events as well as their size can have significant impacts on the severity of hydromodification. For example, a series of small storm events occurring in close succession can have greater detrimental effects than a single, high intensity rainfall. The small storms occurring one after another provides an extended period of time of elevated flow conditions as well as resulting in long durations of fully saturated soil conditions that will limit infiltration. Continuous hydrologic modeling allows for these antecedent moisture conditions to be dynamically calculated within the model rather than having to assume a particular pre-storm condition when individual storm events are simulated. Both long duration low flow conditions and high intensity storm events can result in the most detrimental hydromodification effects. HMM has used a variety of commercial and freely available hydrologic models, including XP-SWMM, EPA- SWMM, and InfoWorks. The use of continuous hydrologic modeling provides a powerful tool to understand these differing impacts. In Santa Clara County, the BAHM software is used to determine a project s impacts to the hydrology and flow-duration coming from a site for a range of storms. This model allows a designer to input the site stormwater routing, including site design measures, LID measures, and hydromodification management measures to verify 4

7 SANTA CLARA VALLEY URBAN RUNOFF POLLUTION PREVENTION PROGRAM DESIGN, REVIEW AND/OR CERTIFY STORM WATER TREATMENT MEASURES AND HYDROMODIFICATION CONTROL FACILITIES compliance. Compliance is only achieved when the proposed site flow duration is equal to or less than that of the existing site for a wide range of storms, specifically 10 percent of the 2-year storm event through the 10-year storm event. When these flow durations are exceeded, designers must modify the various site components until the project s design components achieve compliance. The following projects present the experience of HMM and its staff in the design of stormwater treatment and flow control facilities within the past five years. Santa Clara Valley Water District (SCVWD), Permanente Creek Flood Protection Improvements SANTA CLARA COUNTY, CA Detailed Description of Project: HMM is currently providing design services for the SCVWD for approximately $30 million of flood protection improvements. Improvements include creation of two detention basins located at Rancho San Antonio County Park and a community baseball field in the City of Mountain View. Basins include inlet and outlet pipelines and structures. Design work includes hydraulic and hydrology, geotechnical investigations, civil earthwork/grading, utilities relocations, structural retaining walls and hydraulic structural elements, traffic control, pipelines, landscape designs for parks and ballfields, public outreach, and permitting and coordination with the City of Mountain View, Santa Clara County, and SCVWD. In addition to general project design, the project must comply with the Municipal Regional Permit for stormwater quality and hydromodification management. The 9-acre Rancho San Antonio County Park site is located adjacent to Permanente Creek in the southern edge of Cupertino. The site improvements include a paved parking access roadway, a new parking area, paved and unpaved maintenance access roads, and trails. The project will incorporate bioretention areas, and pervious pavement. The site will minimize impervious surfaces and plans to utilize infiltration to avoid the need for hydromodification management controls. Design for this project is ongoing. The 5-acre McKelvey Ball Park is located adjacent to Permanente Creek on Park Drive in the City of Mountain View. The flood protection, park, and facilities improvements consist of providing both on-site and off-site improvements. On-site improvements include one detention basin, two baseball fields, seating areas, concession and community buildings, parking area, walkways, a mini-park, maintenance access, a pump station, retaining walls, and landscaping. Off-site improvements include realigning utilities, upsizing utilities to maintain hydraulic capacity, realignment and replacement of sidewalk, roadway pavement replacement within the same footprint, and landscaping. The site will incorporate self-retaining areas, bioretention areas, and infiltration beneath pervious play surfacing.

This project is part of a long-term program known as the City s Green Cities Clean Waters Initiative. Diverse Stormwater Best Management Practices (BMPs) were applied to eight blocks of city streets. Selected applications include a stormwater curb extension, infiltration trenches that provide stored stormwater to street trees, and sidewalk planter boxes with inlet channels which collect drainage from the street. HMM worked closely with the PWD to select and apply the most ideal applications in an effort to green the city streets with landscaping while relieving local flooding problems and combined sewer overflow events through infiltration and evapotranspiration of stormwater. This project s ultimate goal was to capture and infiltrate or evapotranspirate the first inch of stormwater runoff, therefore treating the most polluted first flush of any rain event. The Green Streets program was recognized for its long-term ecological and sociological benefits to the community through greening. Town of Los Gatos, Creekside Sports Park LOS GATOS, CA Detailed Description of Project: As a subconsultant to Callander Associates, Renee Crawford served as the drainage project manager responsible for drainage design, stormwater treatment compliance, and SWPPP preparation for Creekside Sports Park. Located adjacent to Los Gatos Creek, the Creekside Sports Park project involved converting an existing 2.8 acre commercial site into a sports park, including a synthetic turf field, new pervious asphalt parking lot, restroom building, and associated utility and surface improvements. The existing site was more than 90% impervious surface with little opportunity for infiltration. The project was designed to infiltrate the water quality volume for more than 80 percent of the site using under-field storage, pervious pavements, and infiltration trenches. For the small areas of impervious surface which could not utilize infiltration, biotreatment swales were provided.
