The Stormwater Facilities shall be constructed by and have Maintenance performed by the Owner in accordance with the term and conditions of this agreement and the plans and specifications identified in approved Grading Plan Number 13761-G which is on file as a permanent public record in the City of Encinitas. 4. The cost and expense of the Maintenance of the Stormwater Facilities shall be paid by the Owner. The owner is responsible to include necessary provisions in the lease agreement with any present and future tenants that cover the costs of all Stormwater Facilities Maintenance. 5. In the event the Property is subdivided in future, the owners, heirs, assigns, and successors in interest of each such newly created parcel(s) shall be liable under this Agreement for their then pro rata share of expenses reflecting such newly created parcels. r 6. The Maintenance to be performed under this Agreement shall include upkeep, repair, and improvements to adequately ensure the Stormwater Facilities are in proper working order as determined by the City. Upkeep, repair, and improvements under this Agreement shall include, but are not limited to, repairing access roadbeds; repairing, preserving, and providing improvement for the upkeep of drainage structures; removing debris, sediment, oil, grease, and other pollutants as determined by the City; perpetually preserving adequate groundcover and/or other erosion control measures within the Property in order to prevent erosion; and the management of materials, pollutants, and hazardous waste to prevent pollution of the stormwater system or Municipal Separate Stormwater Sewer System (MS4) as referenced in local and State codes. Upkeep, repair, and improvement shall also include other work necessary to repair and preserve the Stormwater Facilities for their intended purposes as well as the restoration of the Stormwater Facilities following any non-permitted modification.

EXHIBIT `C' Minimum Maintenance Requirements for Stormwater Facilities PR-1 Biofiltration with Partial Retention BMP MAINTENANCE FACT SHEET FOR STRUCTURAL BMP PR-1 BIOFILTRATION WITH PARTIAL RETENTION Biofilt ation with partial retention facilities are vegetated surface water systems that filter .water through veget tion and soil or engineered media prior to infiltrating into native soils, discharge via underdrain, or overflow to the downstream conveyance system. These BMPs have an elevated underdrain discharge point that creates storag 2 capacity in the aggregate storage layer.Typical biofiltration with partial retention components include: • Inflow distribution mechanisms(e.g., perimeter flow spreader or filter-strips) • Energy dissipation mechanism for concentrated inflows(e.g.,splash blocks or riprap) • Shallow surface ponding for captured flows • Side slope and basin bottom vegetation selected based on climate and ponding depth • Non-floating mulch layer • Media layer(planting mix or engineered media)capable of supporting vegetation growth • Filter course layer consisting of aggregate to prevent the migration of fines into uncompacted native soils or the aggregate storage layer • Aggregate storage layer with underdrain(s) • Uncompacted native soils at the bottom of the facility • Overflow structure Norm I Expected Maintenance Biofilt ation with partial retention requires routine maintenance to: remove accumulated materials such as sediment, trash or debris; maintain vegetation health; maintain infiltration capacity of the media layer; replenish mulch; and maintain integrity of side slopes, inlets, energy dissipators, and outlets. A summary table of standard inspection and maintenance indicators is provided within this Fact Sheet. Non-Standard Maintenance or BMP Failure If an of the following scenarios are observed, the.>BMP is not performing as intended to protect downstream wate ways from pollution and/or erosion. Corrective maintenance, increased inspection and maintenance, BMP replacement,or a different BMP type will be required. • The BMP is not drained between storm events. Surface ponding longer than approximately 24 hours following a storm event may be detrimental to vegetation health, and surface ponding longer than approximately 96 hours following a storm event poses a risk of vector(mosquito) breeding. Poor drainage can result from clogging of the media layer, filter course, aggregate storage layer, underdrain, or outlet structure.The specific cause of the drainage issue must be determined and corrected. • Sediment, trash, or debris accumulation greater than 25% of the surface ponding volume within one month. This means the load from the tributary drainage area is too high, reducing BMP function or clogging the BMP. This would require pretreatment measures within the tributary area draining to the BMP to intercept the materials. Pretreatment components, especially for sediment,will extend the life of components that are more expensive to replace such as media,filter course,and aggregate layers. PR-1 Page 1 of 11 January 12, 2017 PR-1 Riofiltration with Partial Retention • Erosion due to concentrated storm water runoff flow that is not readily corrected by adding erosion control blankets, adding stone at flow entry points, or minor re-grading to restore proper drainage according to the original plan. If the issue is not corrected by restoring the BMP to the original plan and grade,the [City Engineer]shall be contacted prior to any additional repairs or reconstruction. Other pecial Considerations. Biofilt ation with partial retention is a vegetated structural BMP. Vegetated structural BMPs that are constructed in the icinity of, or connected to, an existing jurisdictional water or wetland could inadvertently result in creation of ex anded waters or wetlands. As such, vegetated structural BMPs have the potential to come under the jurisdi tion of the United States Army Corps of Engineers,SDRWQCB, California Department of Fish and Wildlife,or the U ited States Fish and Wildlife Service. This could result in the need for specific resource agency permits and costly itigation to perform maintenance of the structural BMP.Along with proper placement of a structural BMP, routin maintenance is key to preventing this scenario. PR-1 Page 2 of 11 January 12, 2017 PR-1 Biofiltration with Partial Retention SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR PR-1 BIOFILTRATION WITH PARTIAL RETENTION The property owner is responsible to ensure inspection,operation and maintenance of permanent BMPs on their property unless responsibility has been formally transferred to an agency,community facilities district,homeowners association,property owners association,or other special district. Maintenance frequencies listed in this table are average/typical frequencies.Actual maintenance needs are site-specific,and maintenance may be required more frequently. Maintenance must be performed whenever needed,based on maintenance indicators presented in this table.The BMP owner is responsible for conducting regular inspections to see when maintenance is needed based on the maintenance indicators.During the first year of operation of a structural BMP,inspection is recommended at least once prior to August 31 and then monthly from September through May.Inspection during a storm event is also recommended.After the initial period of frequent inspections,the minimum inspection and maintenance frequency can be determined based on the results of the first year inspections.
