All projects that create and/or replace 10,000 sq. ft. or more of impervious surface on the project site must fill out this worksheet and submit it with the development project application. All restaurants, auto service facilities, retail gasoline outlets, and uncovered parking lot projects (stand-alone or part of another development project, including the top uncovered portion of parking structures) that create and/or replace 5,000 sq. ft. or more of impervious surface on the project site must also fill out this worksheet. Interior remodeling projects, routine maintenance or repair projects such as re-roofing and re-paving, and single family homes that are not part of a larger plan of development are NOT required to complete this worksheet. What is an Impervious Surface? An impervious surface is a surface covering or pavement that prevents the land’s natural ability to absorb and infiltrate rainfall/stormwater. Impervious surfaces include, but are not limited to rooftops, walkways, paved patios, driveways, parking lots, storage areas, impervious concrete and asphalt, and any other continuous watertight pavement or covering. Pervious pavement, underlain with pervious soil or pervious storage material (e.g., drain rock), that infiltrates rainfall at a rate equal to or greater than surrounding unpaved areas OR that stores and infiltrates the water quality design volume specified in Provision C.3.d of the Municipal Regional Stormwater Permit (MRP), is not considered an impervious surface.

Percent Replacement of IA in Redevelopment Projects: (Existing IA Replaced ÷ Existing Total IA) x 100% _______% 3. State Construction General Permit Applicability: a. Is #2.b. equal to 1 acre or more? Yes, applicant must obtain coverage under the State Construction General Permit (see https://www.waterboards.ca.gov/water_issues/programs/stormwater/construction.html) No, applicant does not need coverage under the State Construction General Permit. 4. MRP Provision C.3 Applicability: a. Is #2.d. equal to 10,000 sq. ft. or more, or 5,000 sq. ft. or more for restaurants, auto service facilities, retail gas outlets, and stand-alone uncovered parking? Yes, C.3. source control, site design and treatment requirements apply No, C.3. source control and site design requirements may apply – check with local agency b. For redevelopment projects, is #2.g. equal to 50% or more? Yes, C.3. requirements (site design and source control, as appropriate, and stormwater treatment) apply to the entire site No, C.3. requirements only apply to the impervious area created and/or replaced c. Does the project create and/or replace 5,000 sf or more of impervious surface parking? Yes, C.3. requirements may apply to the entire site – check with local agency No 5. Hydromodification Management (HM) Applicability: a.Does the project create and/or replace one acre or more of impervious surface AND is the total post-project impervious area greater than the pre-project (existing) impervious area? Yes (continue)No – exempt from HM, go to page 3 b. Is the project located in an area of HM applicability (green area) on the HM Applicability Map? ( www.scvurppp.org/hmp-map) Yes, the project must implement HM requirements No, the project is exempt from HM requirements 1 “Retained” means to leave existing IA in place. An IA that goes through maintenance (e.g., pavement resurfacing/slurry seal/grind), but no change in grade is considered “retained”. 2 The “new” and “replaced” IA are based on the total area of the site and not specific locations on site. For example, impervious parking created over a pervious area is not “new” IA, if an equal amount of pervious area replaces IA somewhere else on the site. Constructed IA on a site that does not exceed the total pre-project IA will be considered “replaced” IA. A site will have “new” IA only if the total post-project IA exceeds the total pre-project IA (total post-project IA – total pre-project IA = New IA). 3 Include bioretention areas, infiltration areas, green roofs, and pervious pavement in PA calculations.

Per Cupertino Municipal Code Chapter 19.28.120, the tree must be at least a 24-inch box with low to moderate water using tree that typically grows to a mature height of more than 30 feet, planted at a minimum height of six feet, as measured from adjacent grade. California native trees are preferred. The tree shall be planted in front of new second stories in the center 50% of the front yard setback area. Privacy trees must be a minimum twenty-four (24) inch box tree and eight (8) foot height at planting and privacy shrubs must be minimum ﬁfteen (15) gallons and six (6) feet in height at planting.
