Hydrology and Pump Station Design, Oregon72 acre commercial brownfield that underwent remediation and soil removal prior to

development of 20 acre warehouse building. Vitina lead the design of 4 industrial pump stations

to lift the stormwater from the grade level of the entire site to the existing storm drain system in the

streets. Provided detailed modeling of the existing storm drain and proposed site converted 76

percent of the site from pervious to impervious surfaces. Provided the stormwater management

design for the entire site run-off.

St. Anton Place, Menlo Park, CA10 acre industrial property that was redeveloped into 394 apartment units. The sites location is

directly adjacent to the San Francisco Bay, slough and levee system with flood gates

protecting the site from high tides. Vitina performed hydraulic modeling and design to retain the

85th percentile storm during the event due to the public storm drain being over capacity and the

offsite overland release pattern running through the site. The site also required raising the finished

floors above the floodplain elevation and modeling the overland release patterns to ensure

flooding did not occur upstream of the site. For these reasons the site implemented regional

stormwater management facilities that were sized to treat a majority of the stormwater runoff from

the site after the storm event had passed.

Equinix Expansion, San Jose, CAExpansion of Equinix Data Center in south San Jose. Site’s location is in the hydromodification

zone and required onsite underground detention systems in addition to the at grade bio-retention

planters. Vitina performed a 3rd party review of the sites hydrology report and detention

calculations for the client. She also performed during construction erosion control inspections for

the risk level II Stormwater Pollution Prevention Plan (SWPPP) and installation of the detention

system and planters.

FIRM’S

UNDERSTANDING


HMH is a full-service engineering firm with the experience and staff to maintain our status on the SCVURPPP Qualified

Consultants list. The following sections of this document will outline HMH’s strengths and key aspects of our approach to

stormwater treatment design, review and inspection.

KEY STAFF ROLES AND AVAILABILITY

Our staff includes 17 Professional Engineers registered in California, a Certified Professional in Stormwater Quality

(CPSWQ), a Certified Professional in Erosion and Sediment Control (CPESC), a Qualified Industrial SWPPP Practitioner

(QISP) and 3 Qualified SWPPP Developers (QSD) who deliver dependable support and consultation to guide clients from

the entitlement through construction phases of development projects.

Zef Jimenez will be the principal in charge of design, review, certification and inspection of stormwater treatment best

management practices and hydromodification management facilities. Zef will be supported by a team of qualified

engineers who specialize in stormwater management lead by Vitina Mandella, Alan Le and Megan Cronan. Vitina, Alan

and Megan are members of three different departments at HMH (land planning, land development and public works,

respectively) which provides a multi-disciplinary approach to stormwater design, review and implementation. With

trained stormwater review staff in these three key specialties, HMH has the staff and experience to respond appropriately

to a variety of stormwater projects. Our stormwater team members average over 10 years of experience each in design

and review of stormwater treatment measures and have been stormwater reviewers for various local cities. Our flexible

staffing and shared resources allow us to aggressively respond and deliver stormwater projects. Additional information

about HMH’s Stormwater review staff is included in the Resumes and Certification Tab.

URBAN STORMWATER MANAGEMENT

HMH is committed to providing quality civil engineering, land planning and landscape architecture services to private and

public sector clients on projects of varying size and complexity. HMH prepares stormwater management plans that are

consistent with Provision C.3 requirements and tailored to the specific standards of the local agencies. HMH relies on its

years of experience in the field and its team of stormwater experts, civil engineers, land planners and landscape architects

to provide NPDES support services for private and public sector clients throughout the Bay Area.

HMH has a thorough working knowledge of the Municipal Regional Permit (NPDES Permit No. CAS612008, Order No.

R2-2009-0074) and subsequent Amendment (Order No. R2-2011-0083), which contains amended C.3 provisions

implementing mandatory Low Impact Development (LID) measures, Special Projects criteria and their corresponding LID

treatment reduction credits, green roof design and bioretention soil media specifications, and Hydromodification

Management requirements for Santa Clara County. Since the adoption of Order No. R2-2011-0083 by the San

Francisco Bay Regional Water Quality Control Board in November 2011, HMH has developed Stormwater Control Plans

for numerous development proposals categorized as Special Projects, and/or requiring the use of bioretention measures.

HMH has ongoing and recently completed projects in Campbell, Cupertino, Los Gatos, Milpitas, Mountain View, San

Jose, Santa Clara, Saratoga, Sunnyvale and the County of Santa Clara.

HMH prepares plans, reports and specifications related to C.3 compliance for applicant submittals to permitting agencies

within SCVURPPP jurisdiction. HMH also peer reviews plans, documents and specifications prepared by others for

conformance with C.3 provisions, and will identify and provide written documentation of non-compliant issues. The services

we provide typically include site design and source control strategies, treatment facility design and numeric sizing

calculations for flow and volume-based facilities. In cases where a project is subject to hydromodification requirements,

26


HMH will review proposed detention facility designs utilizing hydrology models developed to compare pre-development

to post-development flows (specifically, the BAHM model), and prepare detention sizing calculations to mitigate increased

flows.

Through its CASQA membership and participation in the CASQA BMP Subcommittee and annual conferences, HMH

stays abreast of current issues and developments involving stormwater regulations at the State level, as well as the latest

technological advances.

HMH has maintained close professional relationships with local public agencies. We seek to actively engage local public

agency staff and consultants though collaboration with professional organizations such as the American Planning

Association to sponsor outreach events related to stormwater management and other sustainability-related topics. In the

last two years, HMH worked closely with City of San Jose staff to assist with the City’ss update of their stormwater standard

notes and details and well as provide input and feedback on the City’s internal staff training program for stormwater design

review. Our ability to network through personal relationships with stormwater industry professionals and agency personnel

enables effective coordination for the timely and accurate completion of tasks and delivery of work products. Our goal is to

find solutions agreeable to both project applicants and permitting agencies.

HMH’s experience in stormwater management and involvement in both the private and public sectors place us in a prime

position to provide third party review services that balance the interests of both parties while adhering to State and

Regional codes.

CONTINUOUS STIMULATION HYDRAULIC MODELS

Provision C.3.g of the Municipal Regional Permit requires that projects subject to the Hydromodification Management

(HM) Standard must prevent stormwater discharges from increasing the erosion potential of the receiving stream over the

pre-project condition. Such projects must demonstrate that post-project runoff does not exceed estimated pre-project

runoff rates and durations.

While the inclusion of LID measures and landscape-based treatment controls in the project design can contribute to a

reduction in post-project flows and volumes, they should be used in conjunction with a flow duration control facility to

achieve compliance with the HM standard. Detention facilities can be designed to function as flow duration control

facilities by using continuous simulation hydrologic models that simulate runoff under pre-project and post-project

conditions, generate flow-duration curves, and provide sizing requirements for the facility and its outlet structures. The

basic function of the flow duration control facility is to detain and slowly release that portion of the post-project runoff that

constitutes the increase in volume between the pre-project and post-project condition. The facility should be designed so

that the discharge pattern resulting from the model run matches the pre-project flow-duration curve.

HMH’s stormwater management team includes staff that have received training in the use of continuous simulation models,

including the most recent version of Bay Area Hydrology Model (BAHM 2013). HMH staff have been using the BAHM

model to properly size surface and underground detention storage facilities for development projects located in South Bay

communities including San Jose, Fremont and Los Gatos since 2009.

27


ON-SITE THIRD-PARTY INSPECTIONS

In addition to third party reviews, HMH is applying to be included on the list for consultants qualified for third-party

inspections. The increasing demand from City agencies for third-party inspection has encouraged HMH to acquire

additional staff and training to enable HMH to be qualified for this service. HMH staff has extensive experience inspecting

LID treatment facilities and have attended classes and seminars on C3 design and field inspection. We have been

providing our clients with design and inspection services of their installed post construction stormwater BMP’s for over 15

years. We provided verification that their installation was consistent with their design. Additionally, HMH staff has over 8

years’ experience performing inspections of erosion and sediment controls during construction under the NPDES General

Permit and site specific SWPPP. During these construction inspections our engineers oversaw the installation and protection

of the post construction BMP’s and performed final installation and operation inspections of the post construction BMP’s. In

addition, HMH staff has assisted industrial site owners with inspections of installed BMP’s demonstrating high effluent levels.

Our staff provided the design and oversaw the installation of revised and/or additional treatment controls to reduce the

effluent levels to below the Numeric Action Level (NAL) bringing the site into compliance under the State’s Industrial

Stormwater Permit.

HMH PROJECT EXPERIENCE

Our staff of over 80 employees includes Professional Engineers, Landscape Architects, Planners, and Surveyors. This

diverse collection of technical resources is a key component of HMH’s success. With broad technical and professional

experience in a single office, we possess years of practical knowledge which is easily accessible to all staff.

HMH has numerous recently completed projects in which feature traditional and innovative storm water treatment and

hydromodification systems. More detailed project descriptions can be found in the Qualifications Tab and within our

Key Staff resumes.

For over fifty years, this site has been the home of The Flea Market, providing for its evolution from a small swap meet to a well-known landmark that included over 6,000 vendors, attracting over four million visitors annually. With changing surrounding land uses and the BART extension to the immediately adjacent Berryessa station, the site’s best use has also evolved.

This master-planned, mixed use transit village is the most significant project in Silicon Valley. The 120-acre site has been planned to include up to 2,800 urban residential units (ranging from single-family detached to high rise towers), mixed use and commercial developments, parks, regional trails, a school, and riparian open space along both Coyote and Penitencia Creeks. Significant on-site and off-site infrastructure is required as part of the development including reconstruction and widening Berryessa Road into a 6-lane arterial roadway, vehicular bridge over Penitencia Creek, complete storm drain system with regional solution for stormwater runoff mitigation, major sanitary sewer diversion pipeline, offsetting improvements to surrounding roadway, undergrounding existing overhead utilities, and contributions toward major freeway interchange improvements.

HMH is providing complete services that include Conceptual Master Plans; land use entitlement management and processing; preliminary analysis, master planning and final design for roadway and utility infrastructure; analysis and coordination with the City of San Jose for Citywide Master Utility Plan integration, analysis, layout, feasibility studies, and design for negotiated off-site improvements; design and integration of regional stormwater mitigation facilities; Landscape Architectural design for community open space, trails, and private development; topographic surveys, mapping, and construction staking; and coordination between land owner and developers.

The first phase of this project is nearly complete with 242 single-family detached and attached units. Construction of the next phase of this multi-phased, multi-year project is underway.

This prominent site, located in the center of Santa Clara Valley, boasts a rich history

of discovery, hard work and success. This small group of hills in San Jose has hosted

Tamien people in search of chert, grazing cattle on a dairy farm, AT&T and County

communications facilities, and miners in search of raw construction material and

minerals.

In 1991, the Communications Hill Specific Plan was adopted by the City of San Jose,

creating the groundwork for smart growth development with a new future to host a

master plan to create higher density housing with walkable outdoor amenities that tie

into regional transportation. Now, much of the vision has been built (most of the

design has been performed by HMH), but the last phase of the residential

construction is most significant. The remaining 332 acres will include up to 2,075

residential units, mixed use development with 67,000 square feet of commercial

space, a school, parks, trails, open space, and a 55-acre industrial park for up to

1,440,000 square feet.

HMH is providing complete services that include conceptual site and grading plans;

land use entitlement management and processing; preliminary and final design for

roadway and utility infrastructure; analysis and coordination with the City of San

Jose for multi-modal transportation improvements; feasibility studies, and design

for required off-site improvements; design and integration of regional stormwater

mitigation facilities; Landscape Architectural design for residential neighborhoods;

topographic surveys, mapping, and construction staking; and coordination between

owner, agencies and developers. The first of four phases is now under construction.

HMH was tasked with creating a space that was engaging, unique, team-oriented,

amenity-rich, and reflective of the design trends for office buildings in the area.

Prior to the updates, the layout of the campus had the reception areas facing

outwards, which reduced employee engagement. With the changes, the layout

of the design has it so that the reception areas are facing towards the campus. In

addition to the layout updates, the color palette was also updated to reflect a more

vibrant, young, and fresh feeling of the Silicon Valley Area.

HMH provided landscape architecture, civil engineering, land surveying, and

stormwater compliance services.

Some of the key design elements for the market-ready project include feature walls,

drought-tolerant planting, creative paver design layout, and a nature trail.
