This project involves the development of approximately 1,100 acres near Marysville, California, into an eco-friendly, upscale retirement project consisting of approximately 2,000 units, a wellness center and 350 acres of conservation lands. The conservation lands, formerly used for the production of rice, are being converted to wetlands to provide a safe resting area for migratory fowl. PERMCO was responsible for providing a wide range of civil engineering services including project management, aerial topography, site constraints assessments, coordination with Yuba County officials and property owners, lot line adjustments, tentative and final map development, etc.

PERMCO Engineering & Management has served as the City of Clayton's Public Works and Engineering Department for over twenty years, an explosive period which has seen the City double in size and triple in population. Responsibilities include providing plan checking and construction inspection services on all private and municipal projects as well as interfacing with elected and appointed city staff, officials and citizenry. PERMCO's Principal, Rick Angrisani, has served the City of Clayton as City Engineer since 1986, providing project management and civil design while overseeing the construction inspection and management of all projects within the City Limits. Mr. Angrisani is also responsible for the administration of the City's various assessment districts, including a Geological Hazard Abatement District, Street Lighting Assessment District, Community Facilities District and Landscaping/Lighting.

Our on-call contract with Dublin has allowed us to assist the City with over twenty projects since December 2000. Specific duties included civil design, permit-processing and construction document preparation for road improvements (Annual Street Overlay Projects FY2000/01, 2001/02, 2002/03, 2003/04; 2006 Pavement Rehabilitation Project, 2007 Slurry Seal Project, 2009 Pavement Rehabilitation and 2009 Slurry Seal Projects) and bike trail projects (Alamo Canal and Alamo Creek Bikepaths), as well as preparation of PS&E, project award and project completion packages, final reports and invoices for submission to Caltrans in order to expedite the obligation and/or receipt of Federal transportation funding for participating projects.

Services provided to date under this contract include the preparation of detailed project plans, specifications and cost estimates; pavement evaluations; sidewalk, trail and bike path improvements; Storm Water Pollution Prevention Plan (SWPPP) development; and permitting, processing and coordination with Caltrans, Army Corps of Engineers, Department of Fish and Game, East Bay Regional Park District, Zone 7 Flood Control District, and the Regional Water Quality Control Board for funding and permitting approvals.

PERMCO is also under contract to the Dublin Housing Authority to provide pavement and drainage improvement design on an on-call basis. To date, we have provided civil design services on a project to widen and improve an existing fire access road as well as sewer and pavement repairs for the Arroyo Vista subdivision.

PERMCO was responsible for the design and construction management of this project to eliminate the overflow problem existing within the City of Burlingame's interceptor sewer system. PERMCO prepared a final design report and construction documents in 1997 in preparation for the construction management portion of this project. The computer modeling program used in the design (Hydroflow) allowed various methods of flow input, expeditiously changed design parameters, and produced flow tables and HGL profiles. The new designs PERMCO generated with that program allowed the firm to recommend smaller interceptor lines than those presented in the pre-design report. The final phase project entailed installation of approximately 9,000 linear feet of trunk line varying in size between 18 and 48 inches with depths ranging down to 20 feet and an elevation of -8. Construction methods included open trench, pipe jacking, and a significant amount of microtunneling to minimize disturbance to the City's business area.

Various Projects

• Wren Avenue Elementary School – Drop-Off Lane
• Sequoia Elementary School – Creek Erosion Repair and Storm Drainage Improvements
• Loma Vista Adult Education Center – Sanitary Sewer Rehabilitation
• Pleasant Hill Adult Education Center – Parcel Map Development
• Diablo View Middle School – New Construction
• Mount Diablo Elementary School – Slope Repair

PERMCO acted as assessment engineer on the construction management phase of this major community development endeavor funded for approximately $27,000,000 of infrastructure (including $18,000,000 for right-of-way acquisitions, financing and bond issuance costs). Savings in construction costs — PERMCO completed the originally scheduled projects at 15 percent under budget — and unanticipated earned interest allowed the list of improvements to be greatly expanded by the client, thereby increasing the construction budget to approximately $32,000,000 and adding two years to the original construction schedule.

Grading/Infrastructure

For this phase of the Oakhurst Assessment District PERMCO performed construction management of the movement of more than two million cubic yards of dirt and the construction of two miles of streets. Construction of the streets was preceded by the installation of two miles each of sanitary sewers and water mains, 1.5 miles of storm drains, and two miles of gas and electrical facilities. The project involved three-fourths of a mile of a four-lane arterial roadway with curbs, sidewalks and a median island as well as the installation of four traffic signals enhanced with opticom capabilities. The developer of the Oakhurst Country Club conducted the grading in conjunction with the movement of 10,000,000 cubic yards of material. The grading operation addressed the repair of over 80 landslides, which required the removal and replacement of more than 1,000,000 cubic yards of material. PERMCO's responsibilities for that portion of the work included review, approval, and inspection of the grading and landslide repair plans.

In the infrastructure portion of the project, complications arose due to the aforementioned repair or treatment of over 80 landslides, in addition to many springs, old drainage courses, and adverse road bedding conditions. This phase required 700 linear feet of double 6' x 12' box culvert, 400 linear feet of triple 10' x 12' box culvert, 800 linear feet of 84" CIPP, and an 8' x 10' x 15' high dissipater structure. PERMCO's preliminary design review led to the rejection of several proposals which would have significantly affected the existing creeks, including connecting the 84" pipe to the triple box culvert. The final design proposed by PERMCO discharged the 84" pipe into a different section of the creek (from the box culvert) through a unique dissipater structure. PERMCO performed the final plan check and prepared the bid package for the City. After the award of the contract, PERMCO provided the construction inspection and material testing as well as construction administration.

Landscaping Phases 1A, 1B and 1C

These portions addressed the installation of irrigation and landscaping of many miles of arterial roadways constructed previously under different contracts and involved the construction of walls, walkways, horse trails and lighted development identification monuments. Careful coordination was required with two oil companies due to large transmission mains running through the project area. A unique feature of this project was the construction of a large water feature consisting of two ponds connected with waterfalls and decorative spray heads, all of which were environmentally controlled to reduce water usage.

Recreation Facilities

This portion addressed the construction of five large reservoirs, a pump station and park. The community park consisted of three large baseball diamonds, a soccer field, two sets of restrooms, concession stands, bleachers, ADA-accessible tot lot, parking areas, and many picnic areas and hiking trails. The baseball fields were constructed on an imported sand base, requiring the installation of several thousand feet of sub-drains and extremely careful material quality control.
