Prior to the issuance of a Final Certificate of Occupancy, the developer shall comply with City of Milpitas provisions for obtaining business licenses (including amendments to existing licenses) for the building occupant.
D. Infrastructure, Grading and Construction. Any and all approvals, decisions, reviews or actions required under this section and required for development within the Milpitas Commercial Specific Plan area shall be ministerial, final and not subject to appeal, and shall be processed pursuant to Section XI-10-
11.07(E), Administration, of this Specific Plan.
1. Infrastructure.
a. General Provisions. Any development in the Specific Plan area shall comply with the following:
i. All existing on-site public utilities shall be protected in place and if necessary relocated as approved by the City Engineer. No permanent structure shall be permitted within City easements and no trees or deep-rooted shrubs are permitted within City utility easements, where the easement is located within landscape areas.
ii. Submittal of the Sewer Needs Questionnaire and/or Industrial Waste Questionnaire is required with any building permit application. Payment of the storm water connection fee and treatment plant fee shall be paid prior to building permit issuance.
iii. Developer must pay all applicable development fees, including but not limited to, plan check and inspection deposit, and two and one-half percent (2.5%) building permit automation fee. These fees are collected as part of the secured public improvement agreement. The agreement shall be secured for an amount of one hundred percent (100%) of the engineer's estimate of the construction cost for faithful performance and one hundred percent (100%) of the engineer's estimate of the construction cost for labor & materials. All fees shall be paid prior to building permit issuance. iv. Before building permit issuance, developer shall obtain design approval from the City Engineer pursuant to Section XI-10-11.07(F), Environmental Performance Standards, of this Specific Plan, for all necessary public improvements along Ranch Drive, including, but not limited to, the installation of new pedestrian crosswalk and ped-flashing warning signals, new mid-block ramp, signage and striping, and installation of new median. Developer shall bond for such improvements and execute a secured public improvement agreement. The agreement shall be secured for an amount of one hundred percent (100%) of the engineer's estimate of the construction cost for faithful performance and one hundred percent (100%) of the engineer's estimate of the construction cost for labor and materials. All public improvements shall be constructed to the City Engineer's satisfaction and accepted by the City prior to building occupancy permit issuance.
v. At the time of building permit application, developer shall pay any project job account balance due to the City for recovery of review fees. Review of any permit submittals will not be initiated until balance is paid in full.
b. Water Facilities. The Specific Plan area will receive water service from the City of Milpitas. The City of Milpitas's Urban Water Management Plan indicates that under normal water years, water supplies are sufficient to serve demands within the City through 2030. Under multiple dry year scenarios, demand is expected to surpass supply as soon as 2010. Because the Specific Plan area has an existing building, that building's water demand is accounted for in the City's water demand projections. Development within the allowable Floor Area Ratio for the Specific Plan area would not create increased potable water demand that would adversely impact the water system. Development may be suspended, however, prior to building permit issuance if necessary to stay within available water supplies and will remain suspended until water is available. The City shall provide Developer with written evidence that available water supplies do not exist prior to suspending any development within the Specific Plan area. The Specific
Plan area is estimated to generate ten thousand nine hundred (10,900) gallons per day of water demand.
Implementation of the Specific Plan will not require new or expanded water facilities.
Development in the Specific Plan area must install the following indoor water conservation measures prior to issuance of the final certificate of occupancy to reduce overall demand for potable water: low- flow or ultra-low-flow toilets and urinals; and sensor-activated faucets in restrooms. c. Wastewater Facilities. The Specific Plan area would convey wastewater via municipal sewage infrastructure maintained by the City of Milpitas to the San Jose/Santa Clara Water Pollution Control Plant. A wastewater trunk line is located in North McCarthy Boulevard from SR-237 to the Milpitas Pump Station located at Dixon Landing Road. The trunk line ranges in diameter from thirty-six (36) to forty-eight (48) inches. Development within the allowable Floor Area Ratio for the Specific Plan area would not create increased effluent generation that would adversely impact the sewer system or treatment plan capacity. Development may be suspended, however, prior to building permit issuance if necessary to stay within the safe allocated capacity at the San Jose/Santa Clara Water Pollution Control Plant and will remain suspended until sewage capacity is available. The City shall provide Developer with written evidence that available sewage capacity does not exist prior to suspending any development within the Specific Plan area. The Specific Plan area is estimated to generate six thousand three hundred ninety (6,390) gallons per day of effluent. Implementation of the Specific Plan will not require new or expanded wastewater treatment facilities.
Development in the Specific Plan area will be required to pay a Treatment Plant Fee, a standard requirement for new development projects.
d. Storm Drains. Implementation of the Specific Plan will not require new or expanded offsite storm drainage facilities. However, at the time of building permit plan check, the developer shall submit a grading plan and a Drainage Study prepared by a registered Civil Engineer that recommends adequate drainage facilities to properly accept and convey drainage flows from the Specific Plan area. The study shall be reviewed and approved by the City Engineer, pursuant to Section XI-10-11.07(E), Administration, of this Specific Plan. Developer shall incorporate the conclusions and recommendations of the approved Drainage Study prior to building permit issuance. e. Solid Waste Disposal. Republic Services provides solid waste and recycling services to the City of Milpitas, including the Specific Plan area. During construction, it is estimated that the Specific Plan area would generate approximately five thousand seven hundred thirty-seven (5,737) tons of solid waste.
During operation, it is estimated that the Specific Plan area would generate approximately 361.7 tons of solid waste annually. Before starting construction in the Specific Plan area, developer shall retain a qualified contractor to perform construction and demolition debris recycling. Developer must document, to the satisfaction of the City of Milpitas, that construction and demolition debris was recycled. Before building permit issuance, developer shall show on-site facilities necessary to collect and store recyclable materials. The facilities shall include receptacles in public spaces that are of high-quality design and identify accepted materials. Business owners in the Specific Plan area must comply with best management practices for the handling of solid and food wastes, as permitted by and in compliance with local and state solid waste disposal regulations.
f. Natural Gas. PG&E will provide natural gas service to the Specific Plan area and has available natural gas supplies and appropriate transmission capacity to serve the Specific Plan area. The Specific Plan area's estimated annual natural gas consumption is 8.79 million cubic feet. g. Police Protection. The Milpitas Police Department will provide police protection to the Specific Plan area. No new or expanded police protection facilities are necessary to serve the Specific Plan area. h. Fire. The Milpitas Fire Department will provide fire protection and emergency medical services to the Specific Plan area. No new or expanded fire protection facilities are necessary to serve the Specific Plan area.
i. Electricity and Telephone. The Specific Plan area is located within PG&E's service territory.
PG&E would provide electrical services to the Specific Plan area. PG&E has available electricity supplies and appropriate transmission capacity to serve the Specific Plan area. The Specific Plan area's estimated annual electricity consumption is 2.37 million kilowatt hours.
Telephone service to the Specific Plan area will be provided by AT&T. j. Schools. Prior to the issuance of building permits, the developer shall pay school impact fees.
Impact fees are currently forty-seven cents ($0.47) per square foot.
2. Project Access. Access to the Specific Plan area allows for safe and efficient travel to and from the area. Administrative provisions and signage of the Specific Plan will facilitate direction and access throughout the area. Public transportation exists in the Specific Plan area and a direct pedestrian connection links the existing retail building with the Ranch Drive sidewalk, allowing for safe and convenient access between the existing retail building and the bus stop. A designated pedestrian connection between the existing retail building and the balance of the McCarthy Ranch Marketplace to the south and Ranch Drive to the north exists and will be maintained with any development of the Specific Plan area.
Vehicular access to the Specific Plan area will be provided by two (2) driveways onto Ranch Drive and a McCarthy Ranch Marketplace driveway entrance located to the southeast of the existing retail building.
The driveways on Ranch Drive are stop-controlled and provide single-lane ingress and egress. Truck deliveries would enter via the northern driveway along Ranch Drive and immediately turn right and travel westbound towards the loading dock. Trucks exiting the site would retrace their path to the northern Ranch Drive driveway.
Prior to the issuance of a Certificate of Occupancy, Developer shall obtain the necessary approvals for the installation of VTA bus stop improvements consisting of retention of the bus stop in its existing location, and installation of a seven-foot by twenty-foot Portland cement concrete shelter pad behind the sidewalk/passenger waiting pad with retaining wall. Bicycle storage facilities shall also be installed prior to the issuance of the final certificate of occupancy. These facilities shall consist of at least one (1) rack located in a visible and convenient location (i.e., near the entrance to the building) and that provides storage equivalent to two (2) percent of the minimum parking requirement in the Specific Plan area.
Developer also shall work with and negotiate in good faith with the adjacent property owner to obtain permission for the design and construction of striped pedestrian crossing and associated median and/or ramp modifications at the shared driveway for McCarthy Ranch Marketplace and Specific Plan area entrances.
3. Grading. Given the relatively level topography within the Specific Plan area, development will result in modest changes to topography and ground surface features. During grading and construction, however, developer shall adhere to all applicable recommendations for abating expansive soil conditions contained in the Geotechnical Engineering Investigation or comparable geotechnical study. Prior to the issuance of grading permits, developer shall prepare and submit a Stormwater Pollution Prevention Plan (SWPPP) to the City of Milpitas that identifies specific actions and Best Management Practices (BMPs) to prevent stormwater pollution during construction activities.
4. Construction. During all construction activities within the Milpitas Commercial Specific Plan area, the following measures shall be implemented:
a. Water all active construction areas and exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) at least two (2) times per day; b. Cover all trucks hauling soil, sand, and other loose materials or require all trucks to maintain at least two (2) feet of freeboard;
c. Pave, apply water three (3) times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites; d. Sweep daily (with water sweepers) all paved access roads, parking areas, and staging areas at construction sites;
e. Sweep streets daily (with water sweepers) if visible soil material is carried onto adjacent public streets;
f. All vehicle speeds on unpaved roads shall be limited to fifteen (15) miles per hour; g. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.
Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used; h. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five (5) minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations). Clear signage shall be provided for construction workers at all access points;
i. All construction equipment shall be maintained and properly tuned in accordance with manufacturer's specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation; and, j. A publicly visible sign shall be posted with the telephone number and person to contact at the City of Milpitas regarding dust complaints. This person shall respond and take corrective action within forty-eight (48) hours. The phone number of the Bay Area Air Quality Management District shall also be visible to ensure compliance with applicable regulations.
5. Fiscal Implementation. Implementation of the Specific Plan including, without limitation, construction of all infrastructure and private facilities contemplated in the Specific Plan, will be financed as follows:
a. All infrastructure necessary to implement the Specific Plan will be privately funded (by way of debt and/or equity financing), except to the extent that the cost of components of the infrastructure is a) funded by development impact fees, fair share contributions and other payments to public agencies and/or b) reimbursed from any public source.
b. All private improvements necessary to implement the Specific Plan will be privately financed (by way of debt and/or equity financing).
E. Administration.
1. Permit Processing. Development within the Specific Plan area that is consistent with the provisions of the Milpitas Commercial Specific Plan and the conceptual site plan, elevations, colors and materials, and landscaping as depicted in Figures XI-10-11-07-6 through -9, and the conditions and requirements set forth in Figure 10, shall be processed under building permit and/or construction plan review and no additional approvals or permits shall be required. Any review or action by City agencies, entities or individuals (i.e., the Milpitas Police Department; the City Engineer; the City Building Department; Planning Director) on such development submittals shall be considered part of building permit and/or construction plan review. The action shall be limited to a determination of compliance with the provisions of the Milpitas Commercial Specific Plan and all applicable building codes and other requirements of the City, County, State and/or other responsible agencies. Building permit and/or construction plan review shall be non-discretionary, final actions that cannot be appealed.
Development that is not consistent with the development standards set forth in the Milpitas Commercial Specific Plan, shall either require a Substantial Conformance Determination, as discussed below, or require approval under the provisions and requirements of the Milpitas Zoning Code for development in the C2 Zone.
Any building permit issuance in the Specific Plan area will be conditioned on the availability of water and sewage capacity as set forth in Sections XI-10-11.07(D)(1)(b) and XI-10-11.07(D)(1)(c). Conformance with the provisions of this Specific Plan do not provide a vested right to the issuance of a Building Permit as water and sewage capacity availability is a material (demand/supply) condition to development on the Specific Plan area.
2. Existing Uses. Operation and maintenance of existing uses or structures in the Specific Plan area are not subject to the provisions of the Milpitas Commercial Specific Plan provided a building permit has been obtained and is still valid at the time of the effective date of the provisions codified in this title. Any expansion or development of existing uses or structures, however, would require compliance with the provisions of the Milpitas Commercial Specific Plan.
3. Substantial Conformance Determination.
a. Purpose. A Substantial Conformance Determination is a mechanism to allow the approval of minor modifications for development under the Specific Plan. A Substantial Conformance Determination may include, but is not limited to, minor modifications to the conceptual plans (Figures XI-10-11.07-6 through-9); inclusion of land uses not listed in Section XI-10-11.07(C)(1) of the Specific Plan; modifications that might be necessary to comply with applicable infrastructure, public services and facilities requirements, and landscape palette; and other issues. A Substantial Conformance Determination does not apply to significant modifications in the basic design of the Specific Plan area; changes to the height or bulk of the approved uses; or increases in the density or intensity of the approved uses unless specifically permitted by the provisions of this Specific Plan.
The purpose of a Substantial Conformance Determination is to ensure orderly development, quality aesthetic design, and safe and harmonious placement of uses within the Specific Plan area. A Substantial Conformance Determination (unless specifically noted otherwise) shall be made by the Planning Director or designee administratively, without the need for a public hearing. In making a Substantial Conformance Determination, the Planning Director or designee shall first make all of the required findings set forth in this section.
b. Guidelines For A Substantial Conformance Determination. The following guidelines explain the requirements for making a Substantial Conformance Determination, and the limits placed on the degree of variance from the provisions of the Specific Plan that can occur as part of a Substantial Conformance Determination.
i. Permitted Land Uses. Land uses not listed as permitted in Section XI-10-11.07(C)(1) of this Specific Plan may be permitted, with a Substantial Conformance Determination, provided that:
(1) The proposed use is compatible with the uses permitted described in Section XI-10-11.07(C)(1) of this Specific Plan; and
(2) The proposed use is similar to and will not cause environmental impacts substantially greater than the other permitted uses set forth within Section XI-10-11.07(C)(1) of this Specific Plan. ii. Infrastructure. Any modifications to the alignment of access roads; parking lot configurations, or adjustments to individual infrastructure facilities plans such as drainage, sewer, water, and utilities shall be subject to a Substantial Conformance Determination by the Planning Director or designee. Prior to making a Substantial Conformance Determination, the Planning Director or designee shall make the finding that the proposed modification will not result in any environmental impacts substantially greater than those which would occur without any modification.
iii. Environmental Performance Standards. The Planning Director or designee may approve minor variations from the environmental performance standards set forth in Section XI-10-11.07(F), Environmental Performance Standards, of this Specific Plan, with a Substantial Conformance Determination. In making such a determination, the Planning Director or designee shall first find that the
proposed variation provides substantially equivalent environmental protection as the originally approved standard.
iv. Conceptual Plan and Other Specific Plan Provisions. Provisions of the Specific Plan including, but not limited to, architectural details; landscape palette; building size, height, bulk, and orientation; parking lot layout; and other plan details may be modified with a Substantial Conformance Determination. In making such a determination, the Planning Director or designee shall be required to find that the revisions requested as part of a Substantial Conformance Determination are consistent with the provisions of the Milpitas General Plan, and will not create impacts substantially greater than those that would have resulted from the original approval of the Specific Plan.
A maximum ten (10) percent modification to permitted lot coverage, setbacks, floor area (other than the maximum allowable with the Specific Plan area), parking and fence and wall heights may be permitted subject to a Substantial Conformance Determination by the Planning Director or designee. In making such a determination, the Planning Director or designee shall be required to find that the revisions requested as part of a Substantial Conformance Determination are consistent with the provisions of the Milpitas General Plan, and will not create impacts substantially greater than those that would have resulted from the original approval of the Specific Plan.
The required parking spaces may be reduced by the Planning Director or designee subject to a Substantial Conformance Determination after preparation of a parking study demonstrating the proposed reduction in parking spaces is justified based on the mix of uses within the Specific Plan area and the use of shared parking between those uses.
A comprehensive sign program shall be submitted to the Planning Director for finding that it complies with the signage requirements of the Milpitas Commercial Specific Plan. Such finding shall be made as a part of building permit and/or construction plan review. Any subsequent sign permit applications that substantially comply with the comprehensive sign program shall be shall be processed as a ministerial building permit and/or construction plan review. Any comprehensive sign program that does not comply with the signage requirements of the Milpitas Commercial Specific Plan shall require a Substantial Conformance Determination.
4. Substantial Conformance Determination Procedure.
a. Application. Applications for a Substantial Conformance Determination shall be made on forms provided by the Planning Director or designee and shall be accompanied by a filing fee, equivalent to the fee for a Site Development Permit application. Applications shall be made by the owner of the property for which the approval is sought, or an authorized agent. b. Hearing. No public hearing shall be required for a Substantial Conformance Determination. c. Action by Reviewing Authority. The reviewing authority for a Substantial Conformance Determination shall be the Planning Director or designee. The reviewing authority shall take action by providing written notice to the applicant or developer approving, conditionally approving, or denying a Substantial Conformance Determination. The action of the Planning Director or designee shall be final with no appeal.
d. Findings. The Planning Director or designee must make a Substantial Conformance Determination if all of the following findings, in addition to those identified above, can be made:
i. The physical characteristics of the site have been adequately assessed, and proposed building sites are of adequate size and shape to accommodate proposed uses and all other features of development. ii. There is supporting infrastructure, existing or available, consistent with the requirements of the Milpitas Commercial Specific Plan, to accommodate the development without significantly lowering service levels.
iii. The development resulting from the determination of substantial conformance will not have a substantial adverse effect on surrounding property or the permitted use thereof, and will be compatible with the existing and planned land uses, as well as the character of the surrounding area. iv. The proposed improvements related to the development resulting from a Substantial Conformance Determination adequately address all natural and man-made hazards associated with the proposed development and the project site.
5. Periodic Review. After receiving a certificate of occupancy, development in the Milpitas Commercial Specific Plan Area is subject to a six-, twelve- and eighteen-month review by the Planning Commission. The review shall be a public hearing to review conformance of the development with the requirements of the Milpitas Commercial Specific Plan.
6. Specific Plan Amendments.
a. Purpose. Specific Plan amendments are governed by Government Code Section 65453 and the Milpitas Municipal Code Section XI-10-57.02.
b. Process.
i. The Specific Plan may be amended or repealed only by a majority of the voters voting in an election thereon.
ii. Notwithstanding subsection (a), upon application of the fee title holder of the Milpitas Commercial Specific Plan area, the City Council may amend the Specific Plan to further the purposes of this Specific Plan, but in no case can such amendment reduce or eliminate the parties' obligation to fund, construct, or cause to be funded or constructed, the public benefits or Environmental Performance Standards required.
F. Environmental Performance Standards. The Specific Plan includes environmental performance standards to ensure that development proceeds with appropriate environmental sensitivity. Environmental studies related to aesthetics, light and glare, health risks, air quality, biological resources, geology, soils and seismicity, hazards and hazardous materials, hydrology and water quality, noise, public services and utilities, transportation and urban decay were conducted for an expansion of the existing retail facility in the Specific Plan area. Environmental performance standards were developed from these environmental studies along with information from the City of Milpitas General Plan.
All environmental performance standards shall be implemented in accordance with the Specific Plan's environmental performance standards and implementation process as outlined in Table XI-10-11.07-6, Milpitas Commercial Specific Plan Environmental Performance Standards. The developer of the Specific Plan area shall bear all costs of implementing the environmental performance standards.

XII-1-3.04 Design and distribution of affordable units
Affordable units shall meet the following requirements:
1. The bedroom mix of the affordable units should be proportionate to the bedroom mix of market rate units, provided that the City may allow a different unit mix to meet other City goals as determined by the City Council.
2. The square footage of the affordable housing units must be reasonably consistent with the market rate units in the development although smaller unit sizes may be allowed by the Director or Building Safety and HousingCity Manager if the developer provides adequate justification and reasons why the provision of small unit sizes would further the City's housing goals and this Chapter.
3. All affordable units shall be reasonably comparable in terms of floor plan and base finish amenities to market rate units in the proposed development.
4. The quality of the exterior design, landscaping, and construction of the affordable units shall be consistent with the other units in the proposed development. When affordable units are built off-site they shall be of equivalent or of higher quality compared with the market rate units.
5. Affordable units shall have the same access to common entrances from the exterior as market rate units.
6. Affordable units shall have the same access to all project amenities and recreational facilities available to market rate units. Off-site projects shall have convenient access to equivalent project amenities and recreational facilities compared to the market rate units.
7. All affordable units shall be reasonably dispersed throughout the project and for residential structures higher than eight stories, the affordable units shall be evenly distributed throughout the bottom 60% of the floors or higher.
XII-1-4.00 Payment of fees in lieu of creation of affordable units Upon request of the applicant and subject to the requirements of this Section 4 as set forth above, the City Council may permit the applicant to pay a fee in lieu of constructing the affordable units that the applicant would otherwise be required to construct pursuant to this Chapter. In-lieu fees shall also be paid for requirements to construct fractional units of less than 0.5 units as set forth in Section XII-1-3.00. The City shall adopt, by resolution, current affordable housing in-lieu fee levels as well as administrative guidelines necessary for the implementation of this Chapter.
Fees paid in-lieu of constructing affordable units must be paid prior to the issuance of the building permit for the project, and fees shall be deposited into the City's Affordable Housing Fund. The in-lieu fee shall be calculated based on the gross square footage constructed for each new residential use, taking into account any fee credits that would be applicable based on existing building area. While accessory dwelling units are not counted towards either calculating or meeting the 15% on-site affordable housing requirement pursuant to Section XII-1-3.00, any payment of in-lieu fees must be based on the total gross square footage of all dwelling units developed as part of the project, including any accessory dwelling units.
Unless otherwise specified by resolution of the City Council or amendment to this Chapter, every July 1, or the following business day, if applicable, the City will adjust the affordable housing fees for inflation using the Engineering News Record Building Cost Index for San Francisco. If this index ceases to exist, the Director of Building Safety and HousingCity Manager shall substitute another construction cost index, which in his/her judgment is as nearly equivalent to the original index as possible.
XII-1-5.01 Applicability
Any non-residential development, applicable under the definition set forth in Section XII-1-2.05, is subject to payment of a non-residential affordable housing impact fee. The City shall adopt, by resolution, current non-residential affordable housing impact fee levels. Every July 1, or the following business day, if applicable, the City will adjust affordable housing fees for inflation annually using the Engineering News Record Building Cost Index for San Francisco. If this index ceases to exist, the Director of Building Safety and HousingCity Manager shall substitute another construction cost index, which in his/her judgment is as nearly equivalent to the original index as possible.
The applicant shall pay the non-residential impact fees prior to issuance of the building permit.
Applicable fees will be determined at time of payment. All payment of fees made to the City under this Chapter shall be deposited into the City Affordable Housing Fund.
XII-2-2.04
"Director" means the City's Director of Building and Housing, who is the person designated by the City Manager to direct and manage the rent review program.

XII-2-4.01
The notice of availability of rent review shall be provided in English and the most commonly used languages within the City as determined by the director based upon the American Community Survey, the most recent census or other reputable source data and shall read as follows:
NOTICE:
Under California Civil Code Section 827(b), a Landlord must provide a Tenant with 30 days' notice prior to a rent increase of 10 percent (10%) or less and 60 days' notice of a rent increase greater than 10 percent (10%). In addition, Chapter 2 of Title XII of the Milpitas Municipal Code requires that a
Landlord must at the same time provide and serve this written notice of the City's Rent Review Program. This program provides a procedure for Landlords and Tenants to meet to discuss issues related to rent increases. Information about this program and a copy of Chapter 2 of Title XII are available on the City's website at www.ci.milpitas.ca.gov, at City Hall located at 455 E, Calaveras Blvd. in Milpitas, California, the Milpitas Public Library located at 160 N, Main St. in Milpitas, California, and other locations designated by the City's Director of Building SafetyCity Manager and Housing. Copies are also available in English and the most commonly used languages within the City as determined by the Director of Building Safety and HousingCity Manager.
You are encouraged to contact the owner or manager of your rental unit whose name is _______ (landlord to insert the name of the Responsible Party) at _______ (landlord to insert email address and telephone number) to discuss this rent increase for your rental unit.
In addition if you have received notice of a rent increase of more than five percent (5%) in the last 12 months, you are also entitled to review by the City's Rent Review Board. To initiate the rent review process, you must request rent review by contacting the Department of Building Safety and HousingCity Manager (landlords will be advised of the name and contact information for the service provider designated by the director that is to be inserted in this notice) within 15 days of the date of the notice of rent increase. Your Landlord will be notified of your request and you will be contacted by a housing professional to discuss the rent increase. Please note that petitioning for rent review does not guarantee a reduction in the rent increase.
At the hearing, the Rent Review Board will make a decision concerning the rent increase. You and your Landlord may agree to accept the Board's decision, The Rent Review Board's decision as to the rent increase is non-binding on you and your Landlord.
Under California Civil Code Section 1942.5 and Chapter 2 of Title XII of the City's Municipal Code, it is illegal for a Landlord to retaliate against a Tenant for lawfully exercising his or her legal rights.
SECTION 3. CALIFORNIA ENVIROMENTAL QUALITY ACT (CEQA)
The City Council finds and determines that the adoption of this ordinance is not a project and is not subject to CEQA review because it does not have the potential for resulting in either a direct physical change in the environment or a reasonably foreseeable indirect physical change, particularly in that it does not alter the use of land or does a most does not do so inconsistently with uses already authorized, prohibited, or regulated by law. (Cal. Code Regs., tit. 14, § 15378.) This ordinance also is not a project because it amounts to general policy and procedure making that does not relate to the enactment or amendment of zoning ordinances or the other activities identified as potential “projects.” (Cal. Code Regs., tit. 14, § 15378(b)(2).) Furthermore, even if considered a project, this amending ordinance is categorically exempt from CEQA review in that it comprises of non-land use regulations or at most minor alterations in land use limitations that do not result in any changes in land use or density (Cal. Code Regs., tit. 14, § 15305, 15378(a)(1)) and by common sense can be seen with certainly that there is no possibility that the activity in question may have a significant effect on the environment particularly in consideration of the activities already permitted, prohibited, or regulated by law (Cal. Code Regs., tit. 14, § 15061(b)(3)). This amending ordinance is also exempt because it does not affect development density established by existing zoning and the City’s General Plan, for which an Environmental Impact Report was already certified, and does not have any project- specific significant environmental effects peculiar to the project or any site. (Cal. Code Regs., tit. 14, § 15183.)
SECTION 4. SEVERABILITY
The provisions of this Ordinance are separable, and the invalidity of any phrase, clause, provision or part shall not affect the validity of the remainder.
SECTION 5. EFFECTIVE DATE AND POSTING
In accordance with Section 36937 of the Government Code of the State of California, this Ordinance shall take effect thirty (30) days from and after the date of its passage. The City Clerk of the City of Milpitas shall cause this Ordinance or a summary thereof to be published in accordance with Section 36933 of the Government Code of the State of California.
CITY OF MILPITAS
AGENDA REPORT
(AR)
Item Title: Approve and Authorize the City Manager or Designee to Negotiate and Execute an Agreement with KONE, Inc. for Library Garage Elevator Modernization (Staff Contact: Luz Cofresí-Howe, Finance Director, 408-586-3111; and Christian Di Renzo, Public Works Director, 408-586-2602)
Category: Consent Calendar-Community Services and Sustainable Infrastructure Meeting Date: 1/7/2025
Recommendation: Adopt a resolution to approve and authorize the City Manager, or their designee, to negotiate and execute a contract for an elevator modernization project for the Library Parking Garage with KONE, Inc. for $464,660 with a contingency of $56,401, subject to an executed amendment, for a total amount not-to-exceed $521,061.
BACKGROUND:
The Milpitas Library facilities and garage are the property of the City of Milpitas. The Milpitas Library lease agreement between the City and Santa Clara County Library Joint Powers Authority, effective starting October 21, 2008, has a term of 30 years with the option of two additional periods of 10 years for a total of 50 years.
The Public Works Department is responsible for maintaining the parking garage and elevators and the exterior of the facility.
The Milpitas Library elevators provide essential public access from the parking garage and are facing significant operational challenges. Many components of the elevator design have become obsolete, resulting in ongoing maintenance and repair challenges. There is a documented history of malfunctions, resulting in substantial repair costs to the City, compromising ADA compliance, and disrupting access for the public. These issues increase the risk of entrapment and safety concerns. Additionally, the lack of available mechanical components, modules, and specific electronics for this type of system further exacerbates the problem.
Since May, both elevators have been non-operational due to vandalism. In September, KONE, Inc. (KONE) successfully restored functionality to one of the two elevator cabs, but the call buttons are still not operational on the fourth floor. Modernizing the elevator cabs with updated components, finishes, and security features is crucial to mitigate vandalism and tampering, which have been identified as contributing factors to multiple system failures.
ANALYSIS:
The proposed upgrade will not just replace the critical elements but also modernize the finishes with tamper- resistant controls and enhanced security features, including manual locking mechanisms. These improvements are expected to significantly reduce incidents of vandalism. The current lead time for materials is 15 weeks, with an anticipated 7 week outage per cab for modernization.
Consistent with the City’s Purchasing Ordinance in the Milpitas Municipal Code, the City where practicable engages in competitive procurement. Nevertheless, Milpitas Municipal Code Section I-2-3.06 Sole Source Procurement specifically authorizes the City Purchasing Agent to determine in writing, after conducting a good faith review of available sources, that only one source exists for the required supplies, material, equipment, or general service, or that there is a compelling reason for using only one source.
The City has an existing contract with KONE for on-call elevator repair services, which extends through August 20, 2025. While this contract did not contemplate a major modernization project for the Library Parking Garage elevator system, conducting a request for proposals (RFP) for these services would be unproductive due to the proprietary track systems of the elevators that only KONE can service. As the current maintenance provider for
these elevators, KONE is already familiar with City-specific infrastructure and operational needs and has a deep understanding of the City elevator systems, facilitating the efficient planning and implementation of modernization efforts. KONE's experience with the City setup ensures smooth integration of new components with the existing infrastructure, reducing compatibility issues. Furthermore, as the incumbent provider, KONE can mobilize immediately without the lengthy preliminary assessments a new service provider, if one were available, would require. This positions them to meet the critical project timeline while maintaining consistency in City elevator controls and maintenance practices, which are essential for long-term operational efficiency and safety. As such, the Purchasing Agent has determined there is a compelling reason for approving KONE as the sole source to perform this elevator modernization project for the Library Parking Garage.
KONE will provide the following services for the repair and modernization:
1. Install modular control upgrades
2. Install vandal resistant fixtures, signals, and security features
3. Install upgraded electronic relays
4. Modernize hydraulic system
The Public Works Department recommends approving up to $521,061 for KONE, which includes a contingency for currently unanticipated additional work that is subject to an executed amendment or change order of $56,401, to modernize the garage elevators. Modernizing the Library elevator system is essential for ensuring safety, efficiency, and reliability for the public. This investment will not only help prevent service disruptions but will also help mitigate health and safety concerns that may arise from outdated equipment. The goal of this modernization project is to provide a more dependable and accessible service for everyone.
POLICY ALTERNATIVE(S):
Alternative 1: Do not approve and authorize the City Manager to execute the agreement with KONE, Inc.
Pros: None.
Cons: Continuing to repair and maintain the outdated elevator system not only risks continued escalating costs, potentially exceeding the cost of the recommended modernization work, but also results in diminished public service and disruptions to operations.
Reason for Not Recommending: Modernizing the elevator system is essential for ensuring safety, efficiency, and reliability for the public. This investment will help prevent disruptions and address health and safety concerns that may arise from outdated equipment, providing a more dependable and accessible service for everyone.
FISCAL IMPACT:
Staff is recommending reappropriating $521,061 from the General Fund Facilities Replacement Reserve to CIP 3406 – City Building Improvements to fund the cost of the elevator modernization project at the Library Parking Garage. Per Council Fiscal Policy No. 53, this reserve is meant to fund major rehabilitation or replacement of City facilities. The current reserve balance is $3,700,000. Of the $521,061 in reappropriated funds, $464,660 will be contracted with KONE, Inc. to complete the project, which includes subcontract expenses for MODA Elevator for cab interior finishes. The additional $56,401 will be held as contingency for currently unanticipated related expenses that may be added to the contract through an executed contract amendment or change order.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
Not applicable. The selection and contractual arrangement do not constitute a project, in accordance with Section 15378 of the CEQA Guidelines. Sufficient funding is in the General Fund Facilities Reserve. As of October 2, 2024, the balance of this reserve is $6.2M.
RECOMMENDATION:
Approve and authorize the City Manager or designee to negotiate and execute a contract for an elevator modernization project for the Library Parking Garage with KONE, Inc. for $464,660 with a contingency of $56,401, subject to an executed amendment or change order, for a total amount not-to-exceed $521,061.

Item Title: Approve and Authorize the City Manager or Designee to Negotiate and Execute a Design Services Agreement with Wilsey Ham for Force Main A Project, CIP No. 6137 (Staff Contact: Christian Di Renzo, Public Works Director, 408-586- 2602; Michael Silveira, City Engineer, 408-586-3303; and Luz Cofresí-Howe, Finance Director, 408-586-3111)
Category: Consent Calendar-Community Development
Meeting Date: 1/7/2025
Recommendation: (1) Approve and authorize the City Manager or designee to negotiate and execute, with approval of the City Attorney, a four-year Design Services Agreement with Wilsey Ham in an amount not to exceed $1,460,412, (2) Delegate authority to the City Manager or designee to execute amendments and change orders as required to extend the Agreement and complete the work for up to a 15% contingency amount; and (3) Delegate authority to the Public Works Director or designee to amend Exhibit "C" entitled Project Schedule of the Agreement as required without additional approvals for the Force Main A Agreement, CIP Project No. 6137.
BACKGROUND:
The City of Milpitas (City) wastewater collection system consists of approximately 160 miles of sewer pipelines, with pipe diameters ranging from 4-inches to 36-inches. The collection system generally flows from east to west and south to north towards the San Francisco Bay. Most of the collection system flows by gravity to the Milpitas Main Lift Station (Main LS) and is then pumped to the San José/Santa Clara Regional Wastewater Facility (RWF) through force mains that are owned and operated by the City of Milpitas.
Force Main A (FMA) is a 36-inch steel pipeline built in 1974 located in a highly corrosive soil environment. It is one of two force mains which convey sewage from the City of Milpitas to the RWF for treatment. The FMA alignment extends approximately 12,000 linear feet, starting at the Main LS crossing into the City San José under Coyote Creek and traversing through the RWF residual sludge management drying beds to terminate at the RWF.
On August 9, 2022 the City conducted a public hearing and adopted the Sanitary Sewer Master Plan (SSMP), which included recommendations to improve/rehabilitate portions of the sewer collection system in addition to FMA. The SSMP provided two options to replace the FMA: (1) commence the design in Fiscal Year (FY) 24/25 or (2) commence the design in FY27/28. Staff evaluated both timeframes and determined that delaying the design to FY27/28 could result in several adverse consequences, including likelihood of increased customer rates and charges, potential increased construction costs due to inflation, and, most significantly, increase the risk of failure. If the FMA were to fail near or under Coyote Creek, it would lead to serious financial and environmental consequences. This failure could result in untreated sewage being discharged into the waterbody, violating the Clean Water Act. Such a violation could subject the City to expensive mitigation costs, potential financial penalties from regulatory authorities, and possibly lawsuits from third-party environmental groups. Additionally, sewer flows would have to be diverted to the smaller 24-inch pipeline, Force Main B (FMB), until FMA is repaired or replaced. Due to the size and alignment of the FMA, repairs or replacement, construction timelines may span three to four years before FMA would be operational. Upon adoption of the SSMP, City Council directed staff to complete a five-year sewer rate study to analyze the impacts of both options on sewer rates and present the findings to City Council.
On December 6, 2022, staff presented the Draft Sewer Rates Study to City Council for review, proposing to begin FMA design in FY24/25 using $6.1 million from sewer revenues and up to $20 million in 30-year bonds.
This strategy aimed to expedite project work, reduce the risk of system failure, and create a more gradual increase in customer rates and charges, ensuring both current and future beneficiaries equitably share the costs of infrastructure investment. The alternative option of delaying the design to FY27/28 assumed all cash funding using sewer revenues which risked an exacerbation of the infrastructure issue, and a greater likelihood of service disruptions that would affect the community, as well as a likely unsustainable spike in customer rates to support the immediate funding need. Upon receiving the Draft Sewer Rates Study, City Council directed staff to proceed with community engagement on the proposed rates, which included beginning the design in FY24/25.
On March 21, 2023, the City conducted a Public Hearing and introduced Ordinance No. 208.55 to approve updated sewer rates for FY23/24 through FY27/28. As part of the adopted 2024-2028 Capital Improvement Program Project No. 6137, funding for the design and construction of FMA (Project) was approved.
ANALYSIS:
On July 18, 2024, the City released Request for Proposals (RFP) 24-RFP931 to seek a design firm with expertise in planning, design, and construction support services for the Project. The scope of work includes three project phases:
Phase 1: This phase consists of tasks primarily focused on Project feasibility, including reviewing existing information, coordinating with internal and external stakeholders including, but not limited to, the RWF, Valley Water and regional and State permitting agencies, evaluating new pipeline alignment options, initiating environmental impacts evaluations, and submitting regulatory permitting applications.
Phase 2: This phase will commence upon completion of Phase 1, after a new FMA alignment has been established and regulatory permits are approved. Phase 2 consists primarily of developing construction documents including, but not limited to, design drawings, technical specifications, engineer’s cost estimates, Project schedule(s) and other supporting documentation, as needed for the public bidding process.
Phase 3: This phase consists of tasks related to construction activities, after the construction contract has been awarded.
The RFP was publicly noticed on the City website and OpenGov, the City e-procurement website, in accordance with City Municipal Code. Upon release, 63 firms downloaded the RFP documents. Three (3) vendors submitted proposal responses by the published closing date of September 3, 2024.
The RFP was evaluated and scored in accordance with the evaluation criteria set forth in the RFP. Following initial scoring, the two highest ranked firms were invited to participate in oral interviews to further discuss their proposals, provide clarifications, and answer questions. One of the two finalists, West Yost & Associates, withdrew themselves from consideration prior to the interview citing current lack of bandwidth to take on the project commitment. Scores for the remaining finalist are as follows:
Evaluation Criteria Max Points Wilsey Ham
Cover Letter & Compliance with RFP 5 3.67
Company Profile 25 18.95
Execution Plan 25 21.25
References 15 11.37
Personnel Assigned 10 6.83
Proposed Compensation 20 17.66
Total Score 100 79.73
Wilsey Ham was the best value proposer in accordance with the evaluation criteria set forth in the RFP.
POLICY ALTERNATIVE(S):
Alternative 1: Not approving a Design Services Agreement with Wilsey Ham.
Pros: None
Cons: Not approving the Design Services Agreement will delay the start of the Project. FMA is one of the most critical components of the City’s sewer system and delaying the Project would risk its failure, which could place undue strain on the City sewer system. It would also be contradictory to SSMP recommendations and prior City Council direction.
Reason for Not Recommending: This would result in delaying construction of a priority capital improvement project, which has the potential to have significant short-term and long-term environmental and financial ramifications for the City.
FISCAL IMPACT:
Should Council approve this contract, the four-year agreement with Wilsey Ham for a Force Main A Project will be for an amount not to exceed $1,460,412. Moreover, the City Manager or designee may extend the agreement and execute amendments and change orders up to 15% as required to complete the work. The funding for this Design Services Agreement was approved in the current Capital Improvement Program budget for Project No. 6137. There is sufficient funding available in the Project budget for the agreement, the contingency, and City administration. Additional funding will be requested during the budget process of the Capital Improvement Program in fiscal year 2026-27 for the approximate amount of $23.4 million to fund the construction of the improvement, construction management and inspection services. The amount of $23.4 million will be funded by $3.4 million in sewer revenues and debt financing of $20 million.

CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
As part of the SSMP adoption, City Council adopted the California Environmental Quality Act (CEQA) Environmental Impact Report (EIR) Addendum (Addendum) to the Milpitas General Plan Update EIR (Milpitas GP EIR; State Clearinghouse No. 2020070348) on August 9, 2022. The City adopted the Milpitas GP EIR on March 9, 2021.
The City was the lead agency for the Milpitas GP EIR. The EIR evaluated potential environmental impacts, which could occur as a result of implementing the Milpitas GP. The impact analysis is intended to programmatically cover the construction and operation of actions to be taken under the Milpitas GP, such as new utilities and other elements of utilities master plans.
CEQA Guidelines (Sections 15162 and 15164) require a lead agency to prepare an addendum to a previously certified EIR, if some changes or additions to the environmental evaluation of a project are necessary.
Preparing an Addendum to the approved Milpitas GP EIR is deemed acceptable to meet the requirements of CEQA. The Addendum summarized the utility master plans as considered in the GP EIR, described additional changes to the Plans, made since the certification of the GP EIR and analyzed any change in environmental effects associated with those changes.
Environmental review of the master plans, along with environmental review prepared for the Certified Milpitas GP EIR led staff to conclude that the master plans would not result in any new impacts not previously disclosed in the Certified EIR, nor would it result in a substantial increase in the magnitude of any significant environmental impact previously identified. For these reasons, an addendum to the Certified EIR met the requirements of CEQA Section 15164. Staff also concluded the proposed master plan changes did not trigger any of the conditions in CEQA Guidelines Section 15162; therefore, a subsequent EIR was not required.
As part of the Wilsey Ham Design Services Agreement, an initial environmental assessment report will be compiled for the Project, to include information concerning existing environmental conditions. The assessment will focus on relevant environmental statutes and regulations, which may include, but are not limited to, the following: CEQA, state and federal Endangered Species Acts, Clean Air Act, Clean Water Act, California Fish and Game code, cultural and archaeological statutes, and noise ordinances. Following the initial environmental assessment report, the Designer will prepare a CEQA Initial Study/Mitigated Negative Declaration (IS/MND followed by a Notice of Intent (NOI) to adopt the MND to fulfill the public noticing requirements of CEQA Guidelines Section 15072. Upon adoption of the MND, the City will proceed with obtaining required regulatory permits for construction of FMA, which include, but are not limited to, applications for the U.S. Army Corps of Engineers 404 permit, the Regional Water Quality Control Board 401 permit, and the California Department of Fish and Wildlife Lake and Streambed Alteration Agreement.
RECOMMENDATION:
(1) Approve and authorize the City Manager or designee to negotiate and execute, with approval of the City Attorney, a four-year Design Services Agreement with Wilsey Ham in an amount not to exceed $1,460,412. (2) Delegate authority to the City Manager or designee to execute amendments and change orders as required to extend the Agreement and complete the work for up to a 15% contingency amount. (3) Delegate authority to the Public Works Director or designee to amend Exhibit "C" entitled Project Schedule of the Agreement as required without additional approvals for the Force Main A Agreement, CIP Project No. 6137.

CITY OF MILPITAS
AGENDA REPORT
(AR)
Item Title: Approve and Authorize the City Manager to Execute a Stormwater Management Facilities Operation and Maintenance Agreement Between the City of Milpitas and Sunnyhills Investors LLC for the Sunnyhills Apartments Project at 1724 Sunnyhills Court (Staff Contact: Christian Di Renzo, Public Works Director, 408-586-2602; and Michael Silveira, City Engineer, 408-586-3303) Category: Consent Calendar-Community Development
Meeting Date: 1/7/2025
Recommendation: Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement between the City of Milpitas and Sunnyhills Investors LLC for the Sunnyhills Apartments Project at 1724 Sunnyhills Court.
BACKGROUND:
On November 17, 2020, the City Council approved the Sunnyhills Investors LLC (Property Owner) application for a Site Development Permit (SD18-0004), Planned Unit Development Amendment (PA19-0002), Tree Removal Permit (TR19-0028) and Environmental Assessment (EA20-0005) to reconstruct the leasing office/community building and construct 44 additional residential apartment units with 87 additional parking spaces and associated site improvements including utilities, landscaping and irrigation, and stormwater treatment measures within an existing 171-unit multi-family dwelling apartment complex on a 12.66 acre site located at 1724 Sunnyhills Court (Project).
The Project is conditioned to comply with State Law and the Santa Clara County Municipal Regional Stormwater NPDES Permit (MRP) issued by the Regional Water Quality Control Board (RWQCB) where new development and redevelopment projects that create and/or replace 10,000 square feet or more of impervious surface are required to incorporate Low Impact Development (LID) post-construction stormwater control measures into their project. LID control measures are considered to be bioretention areas, flow-through planters, permeable pavement, infiltration trenches and tree well filters.
MRP section C.3.h.ii.(1)(a) and Milpitas Municipal Code Title XI Chapter 16 requires property owners of a development project meeting the 10,000 square foot threshold to execute and record a Stormwater Management Facilities Operation and Maintenance Agreement (“Agreement”) with the City for the perpetual operation, maintenance, and annual inspection of LID stormwater treatment facilities.
ANALYSIS:
The Property Owner constructed various stormwater bio-retention treatment areas, low impact development, and integrated management practices for stormwater in accordance with the MRP. The Property Owner will be responsible for the perpetual maintenance and operation of the privately owned stormwater treatment facilities within their private property.
The Property Owner has executed the required Stormwater Management Operations and Maintenance Agreement (“Agreement”) for this Project. The Agreement requires the Property Owner to operate and maintain the installed stormwater treatment facilities in accordance with the MPR and the Property Owner will compensate the City to complete the required annual system inspections.
Staff recommends the City Council approve the Agreement (Attachment A) which has been reviewed and approved by the City Attorney as to form, and by the City Engineer as to content.
POLICY ALTERNATIVE(S):
Alternative 1:
Not approving the Agreement with the City for the operation, maintenance and annual inspection of stormwater treatment facilities.
Pros: None
Cons: The Project will not comply with the conditions of development, the City Municipal Code and the Santa Clara County MRP.
Reason not recommended: The approval of the Agreement allows the City to ensure the Property Owner properly maintains and operates the stormwater treatment facilities in accordance with the Agreement. In addition, the Agreement allows the City to inspect the facilities annually and take enforcement action if the Property Owner is not in compliance.
FISCAL IMPACT:
As required by the Agreement, the Property Owner will pay the City for the required annual inspection of the installed stormwater bio-treatment facilities. No fiscal impact will be realized by the City as a result of this action item.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
The City Council’s approval of the agreement was already reviewed under the California Environmental Quality Act (CEQA) at the time the City Council approved the entitlements for the project through an initial environmental assessment. The Planning Department conducted an initial environmental assessment of the project and prepared an Initial Study and Mitigated Negative Declaration (IS/MND) in accordance with the California Environmental Quality Act (CEQA), including, without limitation, CEQA Guideline sections 15070 et seq. On September 17, 2020, the City posted a Notice of Intent to adopt the MND on the City’s website and the Project site and otherwise complied with the requirements of CEQA Guideline 15072. The IS/MND was available for public review from September 17, 2020, through October 7, 2020. On this basis, the Planning Commission and City Council relied on the previous CEQA review conducted in approving this agreement.
RECOMMENDATION:
Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement between the City of Milpitas and Sunnyhills Investors LLC for the Sunnyhills Apartments Project at 1724 Sunnyhills Court.

Sunnyhills Apartments – Milpitas, CA Page 1 of 3 Ma rch 16, 2021 I. PROJECT DATA
I.A. Project Location and Description
The 2.28-acre site is a portion of the Sunnyhills Apartment Complex located in the City of Milpitas .
The project is within an area bounded by Dixon Landing Road to the North, Washington Street to the South, Arizona Avenue to the East, and the North Milpitas Boulevard to the West.
The existing site is an apartment complex with a combination of landscaped areas and existing buildings, walkways, and parking areas. Runoff currently sheet flows towards the west and is captured by area drains spread throughout the site.
As described in the project Geotechnical Report (prepared by Silicon Valley Soil Engineering and dated 11/2/2020) and applicable excerpts attached as appendix B, the subsurface conditions are generally composed of very stiff clays and silts. These soil types continue to a depth of 18 feet below grade. These silty clays allow an infiltration rate of 0.1 inches per hour. Groundwater was encountered in all borings and stabilized at a depth of 15 feet below the existing grade.
I.B. Proposed Site Description
The proposed development demolishes an existing leasing office and constructs six new two- and three-story apartment buildings for a total of forty-four new dwelling units as well as a new leasing office. The project includes bioretention basins throughout the site and along with storm drain piping and structures which conveys stormwater from the bioretention areas to the existing storm drain system in three locations. Two will be made to manholes on the south side of the project that tie into the existing 42” main. The third will be to an existing catch basin on the west side of the project.
I.C. Opportunities and Constraints for Stormwater Control There are a few opportunities on-site which may be used for storm water control measures. The proposed buildings and parking lot can be graded to flow towards adjacent landscaped areas and bioretention facilities. The existing storm drain pipes and structures that cross the property are fairly deep so there is adequate fall to connect to them and install bioretention measures.
The groundwater table is low enough to allow for infiltration into the ground through the bioretention basins. The poor infiltration rate of the native soil limits the quantity of stormwater handled this way, so most of the stormwater runoff will enter the storm drain system after leaving the bioretention basins.
The project will create more than 10,000 SF of impervious surface and will be required per the Municipal Regional Permit (R2-2015-0049) to utilize low impact development treatment measures (LID). The LID treatment measures are infiltration, evapotranspiration, and bioretention.
The project is not within an area subject to hydromodification management.
II. LOW IMPA CT DEVELO PMEN T DESIGN STRATEGIES
II.A. Bioretention Areas
The project will utilize bioretention basins for both treatment and flow control. Impervious surfaces from the site will sheet flow to perforated curbs adjacent to bioretention areas and allow stormwater to collect, filter, attenuate, and ultimately discharge. Runoff from roofs will collect in downspouts and piped to daylight or bubble up into bioretention areas. A minimum of six (6) inches of ponding
Sunnyhills Apartments – Milpitas, CA Page 2 of 3 Ma rch 16, 2021 depth is provided for each bioretention area that will store and limit rainwater flow to the storm drain system during normal storm events.
II.B. Tree Credits
Tree Credits will be utilized for a portion of the site to offset nominal onsite sidewalk improvements that cannot be directed into the bioretention areas. These areas are kept to a minimum and include a portion of the project site along the northern edge.
III. DOCUMENTATION OF DRAINAGE DESIGN
The individual watershed sizes, an example BMP Sizing Calculation, individual BMP sizing calculations, and BMP details are included in Appendices C through F. All bioretention areas were sized using the uniform flow method and the four percent (4%) rule as described in Appendix D.
These documents are included to ensure that the C.3 provisions of the Municipal regional Permit (MRP) are met by this project and satisfy the stormwater requirements of the City of Milpitas and the County of Santa Clara.
IV. SOURCE CONTROL MEASURES
The following source control measures will be used on site: covered dumpster area drain to sanitary sewer, maintenance, and storm drain labeling. (See Appendix A). These measures will help reduce the pollution entering the stormwater treatment areas and help ensure the efficacy of the treatment measures.
V. STORMWATER FACILI TY MAINT ENANC E
V.A. Ownership and Responsibility for Maintenance in Perpetuity All storm water treatment facilities in this plan will be owned and maintained by the property owner, Sunnyhills Investors LLC.
V.B. Summary of Maintenance Requirements for Each Storm water Facility See the Stormwater Facilities Operation and Maintenance Plan in Appendix G which sets forth a maintenance schedule for each of the treatment facilities built on the site.
VI. PIPE HYDRAULICS AND DRAINAGE SUMMARY
VI.A. Background & Model Criteria
The following section includes a discussion of pipe hydraulics to show the storm drain hydraulic grade line has at least 1 foot of freeboard (per County of Santa Clara requirements) and that the pipe system is sized adequately for a 10-year storm event.
The pipe system was modeled utilizing Storm and Sanitary Analysis extension from AutoCAD Civil 3D 2020 and was performed using the requirements of the City of Milpitas Engineering Guidelines Section XIII. For the purposes of this model, the detention components of this system were considered “full” and were bypassed to develop peak flows in the pipes The model was run with three points of connection to the existing mains, which were assumed to be full and have a starting HGL at the crown of the existing 12” pipe at the tie in connection in the north west portion of the site. This starting HGL was chosen as the highest of the three POCs. A minimum time of concentration of 10 minutes was assumed for this system. The results of this analysis are attached under Appendix I.
Sunnyhills Apartments – Milpitas, CA Page 3 of 3 Ma rch 16, 2021 VI.B. Model Results & Conclusions
The peak flow generated in this model is theoretical to show the pipes as designed are sized sufficiently. The results of the analysis show a theoretical total peak flow rate of approximately 7.61 CFS to the discharge points. As there is no surcharging on any portion of the pipes, we can say that the pipes are sufficiently sized.
The HGL in the model stays about 2 feet below the rim elevations throughout the majority of the system with only two structures closer to, but still exceeding, the 1 foot of minimum freeboard required.
VII. CERTIFICA TIONS
The selection, sizing, and preliminary design of st orm water treatment and other control measures in this plan meet the requirements of the Regional Water Quality Control Board Order R2-2015-0049.

1 INTRODUCTION
Per your authorization, Silicon Valley Soil Engineering (SVSE) conducted a geotechnical investigation. The purpose of this investigation was to determine the nature of the surface and subsurface soil conditions at the project site through fiel d investigatio ns and laboratory testing. This report presents an explanation of investigative procedures, results of the testing program, our conclusions, and our recommendations for earthwork and foundation design to adapt the proposed development to the existing soil conditions.
PROJECT LOCATION AND DESCRIPTION
The project site is located at 1724 Sunnyhills Drive in Milpitas, California (Figure 1 – Vicinity Map). Existing commercial/retail developments bounds the subject site to the west, Dixo n Landing R oad to the nor th, and existing residential developments to the east and south. At the time of our investigation, the site was an irregular shaped, relatively flat parcel of land occupied by multi- unit apartments. Access to the subject property is provided by Sunnyhills Drive from Dixon Landing Road and Sunnyhills Court on Milpitas Boulevard. Based on the preliminary plan prepared by the Project Architect for the subject site, the proposed development, eastern portion of the parcel, will include the removal of the existin g structures and construction of townhomes with associated improvements. Location of the proposed townhomes and our borings are shown on the Figure 2 – Site Plan.
FIELD INVESTIGATION
After considering the nature of the proposed development and reviewing available data on the area, a field investigation was conducted at the project site under the direction of our geotechnical engineer. It included a site reconnaissance to detect any unusual surface features, the drilling of five expl oratory tes t borings to
File No. SV1772
November 2, 2020 SILICON VALLEY SOIL ENGINEERING
2 determine the subsurface soil characteristics, and t he sounding of three penetration tests (CPTs) per ASTM D5778. The borings were drilled and the CPTs were advanced on May 1, 2018. The approximate location of the borings and CPTs is shown on the Site Plan (Figure 2). The borings were drilled to the depths of 20 feet and the CPTs were advanced to the depths of 50 feet below the existing ground surface. The borings were drilled with a truck mounted drill rig using 6-inch diameter solid stem augers.
The soils encountered were logged continuously in the field during the drilling operations. Relatively undisturbed soil samples were obtained by hammering a
2.0-inch outside diameter (O.D.) split -tube sampler for a Standard Penetration Test (SPT), A STM Standard D1586 into the ground at various depths. A 140 - pound hammer with a free fall of 30 inches was used to drive the sampler 18 inches into the ground. Blow counts were recorded on each 6-inch increment of the sampled interval. The blows required for advancing the sampler the last 12 inches of the 18 inch sampled interval were recorded on the boring logs as penetration resistance.
In addition, disturbed bulk samples of the near- surface soil were collected for laboratory analyses. The Exploratory Boring Log contained in the Appendix are a graphic representation of the encountered soil profile; and also show the depths at which the relatively undisturbed soil samples were obtained.
LABORATORY INVESTIGATION
A laboratory -testing program w as performe d to determine the physical and engineering properties of the soils underlying the site.
1. Moisture content and dry density tests were performed on the relatively undisturbed soil samples in order to determine soil consistency and the moisture variation throughout the explored soil profile (Table I).
File No. SV1772
November 2, 2020 SILICON VALLEY SOIL ENGINEERING
3 2. The strength parameters of the foundation soils were determined from direct shear tests that were performed on selected relatively undisturbed soil samples (Table I).
3. Atterberg Limits tests were also perfor med on the nea r-surface soil to assist in the classification of these soils and to obtain an evaluation of their expansion and shrinkage potential (Figure 4).
4. Laboratory compaction tests of the native soil material were performed to determine the maximum dry density per the ASTM D1557 test procedure (Figure 5).
5. One R –Value test was performed on a near surface soil sample for pavement section design recommendations (Figure 6).
6. Two soil samples collected were submitted to Cooper Testing Lab f or corrosivity analysis (Page 18).
The results of the laboratory -testing program are presented in the Tables and Figures at the end of this report.
SOIL CONDITIONS
In Boring B-1, the surface soil consists of 3.0 inches of organic material. Below the organic layer to a depth of 3 feet, a black, moist, very stiff silty clay layer was encountered. From the depths of 3 feet to 8 feet, the soil became dark gray, moist, very stiff silty clay. A color change of brown was noted at a depth of 5 feet.
From the depths of 8 feet to 13 feet, a tan brown, moist, very stiff clayey silt layer was encountered. From the depths of 13 feet to 18 feet, a reddish brown, moist, stiff silty clay layer was encountered. From the depths of 18 feet to the end of the boring at 20 feet, the soil became brown, moist, medium dense silty sand. The
File No. SV1772
November 2, 2020 SILICON VALLEY SOIL ENGINEERING
4 sand was medium grained and poorly graded. Similar soil profiles were encountered in other borings.
Groundwater was initially encountered in all borings at the depth of 19 feet and stabilized to static level of 15 feet after the completion of the drilling operation.
It should be noted that the groundwater table would fluctuate as a result of seasonal changes and hydrogeologic variations such as groundwater pumping and/or recharging. A detailed description of th e soil profile s encountered is presented in Exploratory Boring Log contained in the Appendix.
GENERAL GEOLOGY
The site lies in the Santa Clara Valley, which is part of the Coast Ranges geological province. The Santa Clara Valley occupies the s tructural trough formed by two northwest trending mountain ranges; the Santa Cruz Mountains to the southwest of the valley and the Diablo Range to the northeast. The Diablo Range is predominantly composed of Franciscan Formation, which is uppermost Jurassic to lower Upper Cretaceous eugosynclinal assemblage. The Santa Cruz Mountains are predominantly composed of material formed of Cenozoic shelf and slope deposits. A thick blanket of latest Cretaceous and Tertiary clastic sedimentary rocks and isolated in trusions of serpentine covers large parts of the province.
Folds, thrust faults, steep reverse faults, and strikeslip faults developed as a consequence of Cenozoic deformations that occur very often within the province and some of them are continuing today (CDMG; 1966).
Sedimentary marine strata alternating with non -marine strata record the Quaternary history of the region. The changes of the depositional environment are related to the fluctuation of sea level corresponding to the glacial and interglacial periods. Late Quaternary deposits fill the center of the Santa Clara Valley and most of the strata are of continental origin characterized as alluvial

5 and fluvial materials. The project site is underlain by fluvial deposits (Helley and Brabb, 1971, Rogers & Williams, 1974).
LIQUEFACTION ANALYSIS
A. GROUNDWATER
Groundwater was initially encountered in all borings at a depth of 19 feet and rose to a static level of 15 feet at the end of the drilling operation. Based on the State guidelines and CGS Seism ic Hazard Z one Report 051 [Seismic Hazard Evaluation of the Milpitas 7.5 -Minute Quadrangle, Alameda and Santa Clara Counties, California. 2001 (1/13/06). Department Of Conservation. Division of Mines and Geology], the highest expected groundwater level is approximately 15 feet below ground elevation. Therefore, this depth of the groundwater table will be used for the liquefaction analysis.
B. SUSPECTED LIQUEFIABLE SOIL LAYERS
A computer program named LiquefyPro Version 5.8n (CivilTech Corporation) was used in the liquefaction analysis for CPT-1, CPT-2, and CPT-3. This program is based on the most recent publications of NCEER Workshop and procedure outline in SP117 Implementation. The results show that no potential liquefiable soil layers were identified by LiquefyPro. The liquefaction analysis for CPT -1, CPT-2, and CPT-3 are shown on Figure 7, 8, and 9.
C. CONCLUSION
Since there is no liquefiable soil layer underlying the subject site, the potential for liquefaction is minimal.

GENERAL NOTES
1: Soil classifications are based on the Unified Soil Classification System. Descriptions and stratum lines are interpretive, and actual lithologic changes may be gradual. Field descriptions may have been modified to reflect results of lab tests. 2: Descriptions on these logs apply only at the specific boring locations and at the time the borings were advanced. They are not warranted to be representative of subsurface conditions at other locations or times.

MRP Calculation Worksheet
SANTA CLARA VALLEY URBAN RUNOFF POLLUTION PREVENTION PROGRAM B-14 Appendix B
Section III. Sizing for Flow-Based Treatment Measures, continued
This method uses the Rational Method equation:
Q=CIA
Where:
Q = the design flow in cubic feet per second (cfs),
C = the drainage area runoff coefficient,
I = the design intensity (in/hr), and
A = the drainage area for the BMP (acres)
Step 1. Determine the drainage area for the BMP, A = _____ acres
Step 2. Determine the runoff coefficient, C = _____ from Table B-3.
Step 3. Use a design intensity of 0.2 in/hr for “I” in the Q=CIA equation.
I = __0.2 in/hr___
Step 4. Determine the design flow (Q) using Q = CIA
Q = C I A
Q = (Step 2) (0.2 in/hr) (Step 1)
Q = ______ acres-in/hr
Design Flow, Q = __________cfs10
10 No conversion factor for correct units is needed for the rational formula because (1 acre-in/hr) X (43,560 sq. ft./acre) X (1ft/12 in) X (1hr/3600 sec) 1 ft3/sec or cfs.

CITY OF MILPITAS
AGENDA REPORT
(AR)
Item Title: Approve Final Map and Authorize the City Manager to Execute the Subdivision Improvement Agreement with Toll West Coast, LLC for a Residential Project at 612 South Main Street (Staff Contact: Christian Di Renzo, Public Works Director, 408-586-2602; and Michael Silveira, City Engineer, 408-586-3303) Category: Consent Calendar-Community Development
Meeting Date: 1/7/2025
Recommendation: (1) Approve the Final Map, Tract No. 10626, including all offers of dedications as stated and depicted upon completion and acceptance of improvements; and (2) Approve and authorize the City Manager to execute the Subdivision Improvement Agreement between the City of Milpitas and Toll West Coast, LLC., for a residential project at 612 South Main Street.
BACKGROUND:
On April 4, 2023, the City Council approved a Site Development Permit No. SD22-0007, Conditional Use Permit No. UP22-0003, Vesting Tentative Map No. MT22-0003, and Environmental Assessment No. EA22- 0005 to construct a 57-unit townhome-style condominium subdivision comprised of nine multi-family residential buildings up to 37 feet in height (three stories), with 123 vehicle parking spaces and associated site improvements, located on a 2.35 acre site at 612 South Main Street (Project) by Toll West Coast, LLC (Developer).
ANALYSIS:
The Final Map, Tract No. 10626, for the Project is now complete and ready for approval by the City Council.
The City Engineer has examined the Final Map and determined it is substantially in conformance with the approved Vesting Tentative Map and finds that it conforms to all requirements of the State of California Subdivision Map Act and Milpitas Municipal Code, and the terms and conditions of the Vesting Tentative Map.
The Developer has offered required dedications to the City for public use, including easements for streets, services and utilities, and emergency vehicle access purposes, as depicted on the Final Map. Staff recommends the City Council approve the Final Map and accept the dedications, subject to completion and acceptance of public improvements to be installed by the Developer.
The Developer has agreed to enter into a Subdivision Improvement Agreement (SIA) with the City for the construction of off-site public improvements for the Project which will be completed with the on-site work. The public improvements will be accepted by the City after final map approval and completion of construction. Off- site public improvements to be constructed and accepted by the City include asphalt concrete pavement improvements, concrete improvements including driveway approaches, curb and gutter and sidewalk, landscaping and irrigation, signing and striping, street lights, undergrounding of existing overhead utilities, utility mains and services, and other miscellaneous items of work identified on the improvement plans. The improvements will be completed within one year from the date of the SIA, and the work is guaranteed by bonds or similar securities to be posted by the Developer in the amount of $986,000.00.
The City Engineer has reviewed the public improvement plans (2-1461) and is recommending the City Council approve the Subdivision Improvement Agreement to allow for the construction of public improvements after final map approval.
The parcels associated with the Final Map are subject to annexation into the Community Facilities District No. 2005-1 (CFD 2005-1 Annexation No. 25) and will be brought to City Council for consideration at the same meeting of January 7, 2025.
POLICY ALTERNATIVE(S):
Alternative: Deny approval of Final Map and Subdivision Improvement Agreement.
Pros: None
Cons: The denial of approval of the Final Map and Subdivision Improvement Agreement will cause the parcels to remain vacant and undeveloped. The City would not benefit from the addition of 57 new townhome-style condominiums to its property tax revenues.
Reason for Not Recommending: Staff recommends approval of Final Map and Subdivision Improvement Agreement to allow the Development to move forward.
FISCAL IMPACT:
The Developer reimbursed the City for costs associated with plan review, permitting and construction inspection for off-site public improvements constructed by the Developer. The City will have perpetual ownership and maintenance responsibilities for the improvements following construction and acceptance after the one year warranty period has expired. The Public Works Department provides funding for future maintenance of newly accepted City infrastructure through their operating budget and subject to annual appropriations.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
This project is covered under the scope of activities approved under the Midtown Specific Plan Environmental Impact Report, SCH2000092027, which was certified by City Council on March 19, 2002. On April 4, 2023, the City Council found that the project is exempt from further environmental review pursuant to CEQA Guidelines Section 15332 (In-fill Development Projects) in that the Project is consistent with the General Plan and zoning designation while invoking the State Density Bonus Law waivers from development standards and reduced parking requirements, is located in an urban area that has either been previously developed or adjoins existing qualified urban uses on all of the site’s perimeter and is under five-acres in size, has no value to endangered, rare, or threatened species, would not result in any significant effects related to traffic, noise, air quality, or water quality, and the site can be adequately served by all required utilities and public services.
As a separate and independent basis, the Project is also exempt from further environmental review pursuant to CEQA Guidelines Section 15168 (Program EIR) per the Midtown Specific Plan EIR (SCH2000092027) RECOMMENDATION:
(1) Approve the Final Map, Tract No. 10626, including all offers of dedications as stated and depicted upon completion and acceptance of improvements.
(2) Approve and authorize the City Manager to execute the Subdivision Improvement Agreement between the City of Milpitas and Toll West Coast, LLC.

Item Title: Receive an Update on the Security Improvements at the McCarthy Ranch Sewer Lift Station (Main Lift) and Determine that the Condition Continues to Constitute an Emergency (Staff Contact: Christian Di Renzo, Public Works Director, 408-586-2602)
Category: Consent Calendar-Community Services and Sustainable Infrastructure Meeting Date: 1/7/2025
Recommendation: (1) Receive an update on the security improvements at the McCarthy Ranch Sewer Lift Station; and (2) Determine by a four-fifths vote that the condition continues to constitute an emergency.
BACKGROUND:
Pursuant to Public Contract Code section 22050 and the attached Council Resolution No. 9134, the Director of Public Works, in the case of emergency, may authorize a repair of a public facility and procure the work without giving notice for bids. An emergency is defined as “a sudden, unexpected occurrence that poses a clear and imminent danger, requiring immediate action to prevent or mitigate the loss or impairment of life, health, property, or essential public services.” Additionally, State law requires the Public Works Director, as the City official with delegated authority to take emergency action, to report any emergency authorization and the reason(s) for the authorization to the City Council not later than seven days after the action, or at its next regularly scheduled meeting if that meeting will occur not later than 14 days after the action. Further, the Public Works Director is required to report why the emergency would not permit a delay resulting from a competitive solicitation for bids and the City Council is required to review the emergency action at every regularly scheduled meeting thereafter until the emergency repair is completed. The City Council shall continue to review the emergency action at every regularly scheduled meeting thereafter until the action is terminated. At each review, the City Council shall determine, by a four-fifths vote, whether there is a need to continue the action.
Consistent with applicable State law and Council Resolution, on July 30, 2024, the Public Works Director declared an emergency and authorized the City to contract with Trofholz Technologies and Diamond Fencing to implement various security and access control improvements to the McCarthy Ranch Sewer Lift Station (Main Lift). Further, within the required timeframe the Public Works Director informed the City Council via Information Memorandum on July 31, 2024, regarding the emergency authorization, the reasons for the authorization, and the cost for repair in a not-to-exceed amount of $700,000.
PROJECT/STATUS UPDATE:
The installation of security enhancements by Trofholz Technologies, Inc. has been completed. The materials, hardware, and network connections necessary to operate security cameras, card readers, and motion sensors at the Main Lift facility are now installed and operational. Staff conducted a final inspection of the security enhancement features and concluded this portion of the security improvements project on December 19, 2024.
Diamond Fence Co., Inc. will demolish and properly dispose of the existing fence, and install approximately 1,760 linear feet of new, code-compliant fencing using ClearVU reinforced panels topped with ribbon wire, integrated into the current gate structure. Materials have arrived and fence installation will begin in early January. The estimated project completion date is now anticipated in late January 2025.
FISCAL IMPACT:
Funding for these repairs is available in the City’s Capital Improvement Program (CIP) budget. CIP Project 6124 – Sewer Pump Station Rehabilitation Project will fund the installation of security cameras, card readers, and motion sensors. The funding source of this CIP project is Sewer Infrastructure Fund. The available balance as of 12/18/2024 is $1,277,987.
CIP 6130 – Main Lift Odor Emission Control Project will fund the removal and replacement of the perimeter fencing. The funding source of this CIP Project are Sewer Infrastructure Fund, and Sewer Treatment Fund.
The available balance as of 12/18/2024 is $20,217.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
The emergency repair work is exempt from CEQA, per CEQA Guidelines Section 15301, Existing Facilities and 15302, Replacement or Reconstruction.
RECOMMENDATION:
(1) Receive an update on the security improvements at the McCarthy Ranch Sewer Lift Station. (2) Determine by a four-fifths vote that the condition continues to constitute an emergency.

Item Title: Adopt a Resolution Certifying Election Results and Adding the Property Located at 612 South Main Street into Community Facilities District No. 2005-1 (Annexation No. 25) (Staff Contact: Christian Di Renzo, Public Works Director, 408-586-2602; and Michael Silveira, City Engineer, 408-586-3303) Category: Public Hearings-Community Development
Meeting Date: 1/7/2025
Recommendation: Following receipt of election results from the City Clerk, adopt a resolution certifying election results and adding the property located at 612 South Main Street into Community Facilities District No. 2005-1 (Annexation No. 25).
BACKGROUND:
On April 4, 2023, the City Council approved a Site Development Permit No. SD22-0007, Conditional Use Permit No. UP22-0003, Vesting Tentative Map No. MT22-0003, Density Bonus Permit No. DB22-0002, Tree Removal Permit No. TR22-0014, and Environmental Assessment No. EA22-0005 to allow construction of a 57- unit townhome-style condominium subdivision comprised of nine multi-family residential buildings, and associated site improvements, located on a 2.35 acre site at 612 South Main Street (Project) in the Midtown Specific Plan area which will be constructed by Toll West Coast, LLC (Developer).
ANALYSIS:
The Project is comprised of real property in the City of Milpitas, County of Santa Clara, State of California, described as follows:
•Parcels 1 and 2, as shown on that certain map entitled, "Parcel Map", which map was filed for record in the office of the recorder of the County of Santa Clara, State of California on July 18, 1977 in book 400 of maps, page 39.
The Project is subject to annexation into the Community Facilities District No. 2005-1 (CFD 2005-1). The City has on file a Certificate of Registrar of Voters from the County of Santa Clara certifying that there are zero (0) registered voters within the boundaries of the proposed CFD 2005-1 - Annexation No. 25 for this development.
On January 2, 2025, the property owner voted on agreeing to the proposed annexation. The resolution attached hereto, depending on the results of the election to be determined at the hearing, documents the results of the election for annexation into CFD 2005-1 subject to the provisions of the Mello-Roos Community Facilities Act of 1982, commencing with Section 53311 of the Government Code. While the Act has a number of requirements for annexation and imposition of the special tax, the Developer (as the sole landowner within the annexation territory) has agreed to waive many of the formalities. A copy of the waiver executed by the Developer is on file with the City Clerk.
POLICY ALTERNATIVE(S):
Alternative 1: Deny Annexation of Project to CFD 2005-1 Pros: None
Cons: Denying the Annexation of Project into CFD No. 2005-1 would prevent the City from funding necessary public services through levying special taxes on these parcels.
Reason for Not Recommending: Staff is recommending this action to adequately fund the perpetual maintenance of improvements and services within CFD No. 2005-1.
FISCAL IMPACT:
Staff recommends adoption of a resolution certifying election results and adding the Project into CFD 2005-1 to adequately fund the perpetual maintenance of improvements and services within Annexation No. 25.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA):
This Project is covered under the scope of activities approved under the Midtown Specific Plan Environmental Impact Report, SCH2000092027, which was certified by City Council on March 19, 2002. On April 4, 2023, the City Council found that the Project is exempt from further environmental review pursuant to CEQA Guidelines Section 15332 (In-fill Development Projects) in that the Project is consistent with the General Plan and zoning designation while invoking the State Density Bonus Law waivers from development standards and reduced parking requirements, is located in an urban area that has either been previously developed or adjoins existing qualified urban uses on all of the site’s perimeter and is under five acres in size, has no value to endangered, rare, or threatened species, would not result in any significant effects related to traffic, noise, air quality, or water quality, and the site can be adequately served by all required utilities and public services.
As a separate and independent basis, the Project is also exempt from further environmental review pursuant to CEQA Guidelines Section 15168 (Program EIR) per the Midtown Specific Plan EIR (SCH2000092027).
RECOMMENDATION:
Following receipt of election results from the City Clerk, adopt a resolution certifying election results and adding 612 South Main Street to Community Facilities District No. 2005-1 (Annexation No. 25) ATTACHMENT(S):

Item Title: Receive Progress Report on the Work Completed on the Milpitas Gateway-Main Street Specific Plan (Staff Contact: Jay Lee, Planning Director, 408-586-3077) Category: Community Development
Meeting Date: 1/7/2025
Recommendation: Receive progress report on the work completed on the Milpitas Gateway-Main Street Specific Plan.
BACKGROUND:
The Milpitas Midtown Specific Plan was originally adopted by City Council in 2002 to maximize land use, transportation, and economic opportunities along the City’s historic Main Street and to energize and catalyze mixed-use, transit-oriented development in the Midtown area, also known as the “heart” of Milpitas. Since adoption of the current Midtown Specific Plan, little of the community vision for this area has been realized, and many potential development sites remain vacant and underutilized, especially along Main Street. As part of the update process, the Midtown Specific Plan will be renamed the “Milpitas Gateway-Main Street Specific Plan.” The Milpitas Gateway-Main Street Specific Plan will provide a new vision and strategic policy framework to guide redevelopment and reinvestment in three focus areas and transform this important gateway into an attractive and vibrant destination for the City and region.
On April 6, 2021, the City Council adopted the FY2022-26 Capital Improvement Plan (CIP), which included the Milpitas Gateway-Main Street Plan (Midtown Specific Plan Update) [Plan] as Project No. 3437 (Project), with an initial outlay of up to $960,000 from the Community Planning Fund. On May 26, 2021, the Metropolitan Transportation Commission (MTC) awarded the City of Milpitas an additional $500,000 through its Priority Development Area (PDA) Planning Grant Program to complete the Project.
On September 21, 2021, City Council authorized the City Manager to execute a master funding agreement with the Metropolitan Transportation Commission to receive funding through the PDA Planning Grant Program and a professional services agreement with Ascent Environmental for consultant services to prepare the Project.
Throughout the preparation of the Plan, the Project area expanded to annex adjacent neighborhoods that would benefit from inclusion into the Plan area. An additional redevelopment focus area was also added to maximize the development potential of new opportunity sites. Additionally, City staff determined the scope of work should include preparing zoning regulations and development standards to ensure consistency between the Plan and Milpitas Zoning Ordinance upon Plan adoption rather than amending the zoning map and text later. Furthermore, the existing condition of utilities and infrastructure within the Plan area requires additional analysis and utility improvements to ensure that future development will be adequately served. As such, the professional services agreement with Ascent Environmental has been amended to increase the Project budget from $930,708 to $1,059,708 and extend the termination date from June 30, 2023 to June 30, 2025 to deliver this additional scopes of work.
The work completed thus far is summarized below.
1.Kick-Off Meeting and Site Tour: The Project team held a virtual kick-off meeting on October 26, 2021 to initiate the Project and discuss City goals and objectives, team roles and responsibilities, Project area context and efforts under way, and Plan and focus area boundaries.
2.Material Review and Preliminary Mapping: The consultant reviewed relevant existing and in- progress studies and created a series of maps to depict the local context.
3.Existing Conditions Assessment: The consultant assessed the physical context of the Plan area with a focus on identifying preliminary opportunities and constraints related to land use and development.
Completed deliverables include the Land Use, Zoning and Urban Form Analysis, Market Study, Transportation Analysis, Affordable Housing and Community Benefits Memorandum, and Resilience and Climate Adaptation Assessment. Please refer to the Existing Conditions Memo (Attachment 1) for more information.
4.Community Outreach: To create awareness and excitement about the Project and receive meaningful community feedback, the Project team prepared a Community Engagement Strategy, facilitated two pop-up events, presented at the Council Ad-Hoc Main Street Revitalization Subcommittee, held stakeholder interviews, hosted two community workshops, conducted study sessions with the Planning Commission and City Council, and hosted two meetings with the Technical Advisory Committee.
Please refer to the Council agenda report from April 25, 2023 (Attachment 2) for more information regarding the community outreach and feedback received.
5.Visioning, Scenario Planning, and Plan Strategies and Alternatives: Based on the robust existing conditions analysis and feedback received from the community, Council, and TAC, the Project team prepared a vision memo with the Plan strategies and alternatives related to land use, mobility, and open space. The consultant also conducted a feasibility analysis for three development scenarios to test different development frameworks to ensure that Plan recommendations will be practical and implementable. Please refer to the Vision Memo (Attachment 3) for more information.
6.Draft Plan: The consultant prepared an Administrative Draft Plan for internal review. The Administrative Draft Plan incorporates goals, policies, findings, and strategies from earlier phases of the Project and includes chapters addressing Plan vision and goals, land use and zoning, objective design standards, mobility, and the public realm. Staff, including members of the TAC, reviewed the Administrative Draft Plan and provided detailed feedback to ensure the Administrative Draft Plan addresses City Council priorities and community needs.
7.Environmental Analysis: The consultant initiated the environmental review process pursuant to the California Environmental Quality Act. The Project requires a Subsequent Environmental Impact Report (EIR), which builds off the General Plan EIR as the Project is an implementation of the General Plan.
The Project team prepared a Notice of Preparation and held a public scoping meeting to share the anticipated environmental impacts of the Project and receive preliminary feedback regarding the environmental analysis. The consultant also prepared the Administrative Draft Subsequent EIR, which staff is currently reviewing.
ANALYSIS:
Following staff feedback on the Administrative Draft Plan, the consultant is preparing a Public Draft Plan, which will be released for public review upon completion, to solicit community feedback on the Draft Plan prior to Plan adoption. While the Public Draft Plan is not yet available, a summary of the Plan components and next steps are outlined below.
Vision and Goals
The Plan area is envisioned as a group of neighborhoods that together create a complete community and center for Milpitas. New infill housing and mixed-use development will be paired with complete streets, new urban open spaces, and placemaking to distinguish the Plan area as a walkable and bike-friendly urban community. The guiding principles are organized around four themes: (1) vision and placemaking, (2) land use and development, (3) transportation and access, and (4) open space and community amenities.
The Plan is organized around four focus areas: 1) Main Street District, 2) Crossroads District, 3) Gateway District, and 4) Abbott District. The Plan also identifies the following eight (8) “big moves” to implement the Plan vision:
1. Redesign Main Street as a “shared street” with active, pedestrian-friendly spaces and outdoor dining;
2. Redevelop Serra Center and the Crossroads as a new center for the community;
3. Prioritize commercial activity and active building frontages;
4. Enhance Calaveras Boulevard and Abel Street as multimodal complete street corridors;
5. Create a connected network of new streets, paseos, alleys, and bike and pedestrian linkages to improve access and walkability;
6. Develop a connected open space network with new urban parks and plazas;
7. Integrate streetscape, branding, and public art at gateways, along streets, and in public spaces; and
8. Support district solutions including shared parking and coordinated infrastructure improvements.
Land Use and Zoning
The Plan establishes new mixed-use zoning districts aimed at supporting a mix of residential, retail, entertainment, office, civic, and recreational uses at a variety of scales. The land use strategy emphasizes flexibility and streamlined permitting to incentivize mixed-use redevelopment, especially on identified opportunity sites throughout the Plan area. The Plan increases the maximum floor area ratio (FAR) for nonresidential land uses to encourage commercial development. For residential uses, the Plan provides the following density ranges and heights to encourage redevelopment of underutilized sites into residential development at an appropriate scale in each district:
District Min. Density (du/ac) Max. Density (du/ac) Max. Bldg. Height (ft.) Max. No. of Stories Main Street 20 65 65 5
Crossroads 40 85 85 7
Gateway 18 65 65 5
Abbott N/A N/A 65 N/A
Library 20 65 65 5
Within these density ranges and maximum heights, the expected residential products include townhomes, stacked condos, and apartments. The Plan will also utilize incentive-based zoning to offer various development incentives such as density bonuses and streamlined permitting in exchange for Project features that offer community benefits such as green building, small business retention, public parking, publicly accessible open space, affordable housing, and historic rehabilitation.
In recognition of the importance of local businesses within the Plan area, the Plan identifies retail priority areas and activity streets to require ground-floor retail and well-designed shopfronts along key streets and corners, and active building frontages and robust streetscape improvements along important pedestrian corridors.
Lastly, the Plan establishes moderate parking ratios complemented by a holistic parking strategy to minimize negative parking impacts on existing residential neighborhoods in the area while removing constraints for new development.
Objective Design Standards
The Plan builds on the Citywide Residential and Mixed-Use Objective Design Standards by providing Plan- specific objective design standards that address the following topics: 1) site planning and design, 2) building design and architecture, and 3) pedestrian level design.
Public Improvements
The Plan includes strategies, policies, and specific improvements related to mobility, public realm, and infrastructure and public services to complement and support the development expected in the Plan area.
Mobility
The Mobility Chapter establishes multimodal corridors along Calaveras Boulevard, Serra Way, Main Street, and Abel Street, which are all envisioned as complete streets serving vehicles, transit, bicyclists, and pedestrians. Street cross sections and standards are provided to implement this vision. The chapter also establishes locations and standards for future streets and connections to connect existing roadways and support a more walkable neighborhood grid pattern, while providing policy direction for public transit and public parking.
Public Realm
The Public Realm Chapter establishes policies for new parks, open space, greenways, and plazas within the Plan area to create an interconnected network appropriate for an area with limited undeveloped land. The parks and open space strategy focuses on smaller pocket parks and urban spaces in strategic locations, rather than large parks and open spaces, to ensure existing and new developments are adequately served by recreational facilities. The chapter also covers important topics including creekside open space, underpasses and other infrastructure spaces, privately-owned public open spaces, gateways and wayfinding, public art and murals, and streetscape and landscaping.
Infrastructure and Public Services
The Infrastructure and Public Services Chapter outlines the infrastructure needed to support public services within the Plan area. It sets forth policies and improvement projects for enhancing and expanding public facilities. Topics include storm drainage, flooding, water supply and distribution, sewer, solid waste, energy and technology, fire protection and emergency response, police services, schools, libraries, and childcare.
Implementation
Lastly, the Plan includes an Administration and Implementation Chapter, which outlines a comprehensive list of implementation actions, assigns responsible leads, establishes time frames, and recommends funding options.
The implementation strategy includes both public and private programs and actions to implement the Plan vision, goals, and policies.
Next Steps
The remaining next steps for the Project are outlined below.
1.Public Draft Plan and EIR (late January 2025): Based on staff and community input received, the consultant will refine and finalize the Public Draft Plan and Subsequent EIR for public review and circulation.
2.Final Plan and EIR (May 2025): Following the release of the Public Draft Plan and Subsequent EIR, the Project team will gather final input received during the public review process and prepare the Final Plan and Subsequent EIR.
3.Adoption Hearings (June 2025): The Project team will present the Final Plan and Subsequent EIR to the Planning Commission for recommendation and the City Council for adoption.
If the Plan is adopted, it will go into effect shortly thereafter and City staff will start reviewing development projects within the Plan area against the new land use and zoning requirements. Staff also initiated the Main St. Sense of Place Plan, which will identify specific public improvements along Main Street to implement the Gateway-Main St. Specific Plan, and establish a Plan-specific development impact fee to fund the identified improvements as sites develop on Main Street.
