===Assumption Inspections===
Assumption inspections should be a shared responsibility between the property owner or their project manager, the designers (engineering and landscape design professionals) and construction contractors involved in the project. When the municipality is not the property owner, they may choose to not be involved in performing or reviewing such inspection work but should still receive copies of Assumption inspection records so that an inventory database of permanent stormwater BMPs on private property that connect to municipal infrastructure can be developed and maintained. Other terms for such inspections include deficiency, project acceptance or certification inspections.
At a minimum, Assumption inspections should be performed:
#Immediately after site construction (including landscaping) ends (i.e., the deficiency inspection) prior to substantial completion of construction, release of performance bonds (if applicable) and beginning of the warranty or establishment period, and;
#Prior to termination of the warranty or establishment period (e.g., 2 years after substantial completion of construction), release of any maintenance holdbacks (if applicable) and assumption by the property owner.
Feedback from inspections should be used to correct any deviations from the approved design or material specifications not approved through change orders, deficiencies in BMP function due to how it was designed or installed and to initiate follow up to replace failed plantings that are under warranty. Once satisfactory results from Assumption inspections are achieved the performance bond(s) are released and the property owner assumes the BMP and becomes responsible for inspection and maintenance tasks. At this stage, documentation of results from Assumption inspections, and records describing the maintenance tasks performed over the establishment or warranty period should be provided by the consultant or municipality to the property owner. The municipality should also receive this information if they are not the inspector or owner and the BMP qualifies for inclusion in their program. There are a variety of approaches to ensuring thorough and satisfactory Assumption inspections of LID BMPs are completed prior to assumption by the property owner but the following contractual and administrative strategies should be considered.
====Performance Bonds, Letters of Credit and Cash Sureties====
*A common method for ensuring BMPs are ready for acceptance/assumption at the end of construction and prior to termination of the construction contract is to require that a performance bond, letter of credit or cash surety be submitted by the contractor to the property owner as a condition of the contract, ideally in an amount equivalent to the full cost of the work.
**In such cases, construction contracts should specifically require that thorough inspection and testing of the BMPs be completed to the satisfaction of the property owner or their project manager and design consultants as a condition of Assumption, contract termination and release of the performance bond, letter of credit or cash surety.
====Holdbacks in Construction Tenders or Contracts====
*The property owner can specify in construction tenders or contracts to retain a certain percentage of the total value of the work done for a period of 12 months from the date of final completion.
**In such cases, construction contracts should specifically require that thorough inspection and testing of the BMPs be completed to the satisfaction of the property owner or their project manager, design consultants and construction contractors as a condition of Assumption, contract termination and release of the holdback amount.
